A comprehensive overview of seven ways to optimise your manufacturing process.There are many benefits of optimising a manufacturing process. These include increased production rates, reduced production costs, improved product quality, and improved resource utilisation rates.The Importance of Optimising Your Manufacturing ProcessManufacturing Process Optimisation is the process of improving an existing manufacturing process to reduce the amount of resources or time needed to produce a product. This is typically done by examining and analysing the current process, identifying potential improvements, and implementing those changes.Continuous improvement is the type of attitude that helps us to reach our goals. It is important to commit to the continuous optimisation of it in order to maximise the efficiency of your plant, bring sustainability and more profit.Since it takes a considerable amount of patience and discipline, it’s beneficial to recognise that manufacturing process optimisation is not a one-off activity. Instead, this is something you have to keep in mind and come back to over time, reviewing every part of the manufacturing process, including your staff, machinery, and resources.A common approach is in implementing lean manufacturing principles into your production line. This will help with increasing productivity, reducing defects, and improving quality.In this article, we review seven ways to optimise your manufacturing process where the John Brooks team can help.Identify manual jobs that can be automated. Examine if your production/assembly line can be more automated or better optimised Get expert help to tackle this one step which slows production. Critically assess the performance of existing machinery. Choose to invest in new equipment or different technology, even when you are on a tight budget. Explore energy-saving opportunities by switching to variable speed drives (AC/DC) and electric over pneumatic control. Identify mission-critical data which can be gathered, monitored and controlled. All of it is now possible with an Industry 4.0 mindset.1. Identify manual jobs that can be automated.Regardless of the product that you manufacture, there is without a doubt, room for more automation especially when you consider jobs that are currently done manually.You can argue that one of your top workers has mastered the craft of doing a particular task with accuracy. But with modern technology, most types of repetitive tasks can be easily done by machines with great precision and exclusion of human error.We are now living in an era where robots are taking over manual jobs, the reality of the market is that before going into the expense of introducing robots, a lot of automation can occur through more traditional industrial automation solutions.The starting point is to examine every part of your production/assembly line to uncover where manual labour is involved. Loading products, packaging, and lubrication are just some of the typical manual jobs that are often overlooked.Could certain manual procedures be automated?For starters, you could be doing more by investing in a machine that can do a task more efficiently, which is usually done by a team of workers. You might think it’s expensive but if you compare the amount that you pay for labor per week to the cost of a single machine, you’d really see how much you can save; not to mention the productivity difference between the two.As specialists in industrial automation, John Brooks team see it as our primary role to help automate mundane manual labour in order to increase productivity allowing more time for other tasks that require expertise, thinking and decision-making abilities.2. Examine if your production/assembly line can be more automated or better optimised.The first step here is to understand the current state of your process. This can be done by collecting data on how long it takes for each step in the manufacturing process, how much time is spent on each step, how many defects are made in each step and what the known issues are?Once you have collected this data, you will want to make sure that you are looking at it from the right perspective. You should not just look at the amount of time that is being spent on a certain task, but also take into account other factors such as defects or quality standards. You want to know how much time is spent on tasks that might be detrimental to the company, or ones that need to be improved upon. This is a good place to start asking tough questions.Is everything working in sync or are some processes too fast or too slow?Is there old equipment that is coming to the end of its life span?Would new controls and software help with monitoring, inventory control, or planning? Could you improve or replace your machines and equipment?John Brooks is an engineering company specialising in Industrial Automation for Manufacturing,  Food and Beverage and their sub inudustries of Dairy Farming and Wine making. We pride ourselves on our history of being able to come up with engineering solutions, recommend and find industrial products to meet our customer’s needs and provide support to them with a personal relationship that matters.3. Get expert help to tackle this one step which slows production.Do you have a feeling there is one step that slows everything down?Even if it seems there is no way to improve or control it automatically and you reached the point when having a human controlling it has become expensive and inefficient, ask the experts because there might be something new available to help now.Working with all kinds of manufacturers for over 50 years, our experience is that there is often just ONE step in the whole production line that slows everything down.While there might be a number of reasons how that happened, the task at hand is to identify this ONE part that slows everything down. Here are some of the common situations we come across:Incorrect choice of equipment (motor or other part creates out-of-sync situation) Mismatch between feeding and processing speed on a conveyor Minor Stops / Idling Loss Inconsistent supply of materials or parts And moreIt is truly remarkable how many companies choose to tolerate this one part of the process that slows everything down. Not rocking the boat may be an OK strategy, but when it comes to a manufacturing plant, piece of machinery, or cooling tower operation, it’s better to find a solution.Identifying this mission-critical process that slows production is an interesting and sometimes breathtaking process of discovery. It may create a challenge for any engineering mind. And when it is beyond your understanding or knowledge it’s OK to call on experts, who have the luxury of seeing a huge variety of situations across different industries and can help you find a good solution.By getting help from experts, you’d be able to detect certain flaws on your processes that you yourself might have not noticed before. These experts can offer solutions that would greatly benefit, not just one area or part of your whole process but also the entirety of the plant as well.The John Brooks team is often approached to help with "tricky" situations and we are happy to help. We have 55+ years of experience and the combined expertise of our team across three major centres in New Zealand, we have the backing and support of world-leading manufacturers. That is why we can always reach out to manufacturing experts to seek advice and help specifically for your plant situation.Identifying the part of the process that slows production and finding a solution is one of the most rewarding projects. Therefore, examining the production line to identify areas of improvement is a big part of a continuous improvement mentality, which every manufacturer of quality products is committed to.4. Critically assess the performance of existing machinery.Technology is evolving and what was innovative yesterday is no longer the case. It's time to decide whether you should modernise or enhance your machinery, equipment, processes and technologies after mapping your current workflows.Here are some of the questions you might want to ask and discuss internally first before engaging outside expertise:Have you got new machinery on your production lines that is just not the perfect fit and affects the productivity of your plant? Did you know this can be corrected? Click to read about a case study where our team was able to help.You should also take stock of the resources that you have available for improvement and then prioritise them based on the following criteria:Cost of implementation Urgency of need Impact on customer serviceThe choice of engineering equipment for a plant is a critical decision, as it will affect the plant's productivity and the quality of its products.If you are an engineer, you know that choosing the right equipment for a project is not always easy.There are many factors to consider such as production capacity, energy efficiency and costs. These factors play a vital role in engineering projects and decisions.In the engineering industry, engineers often make decisions by calculating formulas and looking at data. There are many different variables that go into their equations and the calculations can be quite complex.When you are faced with complex calculations to understand the performance of your plan, it’s best to call on the help of experts like the team from John Brooks, because most likely we perform calculations like you need a lot more often such as speed and torque requriments of electric motors and gearboxes and know a lot more about hidden challenges, which we can help you solve.5. Choose to invest in new equipment or different technology, even when you are on a tight budget.Efficiency won't be easy to increase no matter how brilliant your personnel are if the machinery in your production facility is old or even malfunctioning.Therefore, make sure you're prepared to spend money on cutting-edge modern machinery to improve the efficiency of the production process. It can help with product quality improvements, as well as reducing waste and improving product flow.Even when you are on a tight budget it’s beneficial to go over an honest assessment of what it cost you in maintenance, repairs, labour, loss of productivity and possibly stress on the business when you continue to use existing machinery and equipment.A comprehensive understanding of costs involved in the upkeep of the current vs the investment required to get new equipment is a useful exercise, which has to be done annually or at least every few years.Why?Because new equipment and new technologies are coming on the market all the time and what was costly and impossible just yesterday is rapidly becoming commonplace today.Here at John Brooks, we keep an eye on new innovations in everything related to industrial automation including industry 4.0 and data-driven control automation. We even manufacture Control Cabinets ourselves to help monitor plant performance remotely.By the way, new equipment does not mean an overhaul of the whole operation. It can be as simple and as effective as changing a DC motor to an AC one or installing of a smaller, yet powerful motor in a tight spot, where previously no motor could fit well.6. Explore energy-saving opportunities by switching to variable speed drives (AC/DC), Electric to PneumaticMany industries worldwide incur a major cost from energy usage. In today's markets, it is essential to reduce costs in order to survive. One way to reduce energy consumption is by using induction motors with AC or DC variable speed drives.A variable speed drive (VSD) is also known as an inverter or variable frequecy drive (VFD). A variable speed drive is an electronic device that allows a power supply to be controlled by varying the frequency and voltage of an alternating current.Variable speed drives are devices that can be used for industrial and commercial purposes. They are capable of controlling the speed of motors, pumps, fans, and other electric machines. Variable speed drives are a type of Variable Speed Drive that can be used to control the speed of motors, pumps, fans, etc.The benefits of using an AC or DC variable speed drive are:It is more efficient than a fixed speed electric motor. It can save energy by adjusting the input voltage and frequency to match the output load. It can reduce power consumption by up to 50% in comparison to a fixed speed drive by reducing the speed by 20% when necessary.Did you know that fixed-speed motor load applications which are supplied direct from AC line power can save energy when they are operated at a variable speed?John Brooks in-house engineering team of experts can help you implement an energy-saving solution using a Variable Speed Drive. This also gives you greater control of the motor’s performance. The use of a Variable Speed Drive will ensure optimal and sufficient use of energy and can prolong the life of the motor.7. Identify mission-critical data which can be gathered, monitored and controlled.Data is recognised as a massively important driver for the manufacturing process if only it is gathered adequately.Manufacturing companies prduce huge amounts of data. Yet many are not gathering sufficient mission-critical data to be able to draw valuable insights.Naturally, step number one is to introduce necessary controls that can help you gather, manage and analyse data. The next step is to streamline processes and control data processed that allows for detailed analyses at every stage.Once in place the control system monitors the process 24/7.If that sounds too good to be true, it is actually happening right now. All of it is now possible with an Industry 4.0 mindset and a new era of manufacturing.The increasing digitisation of manufacturing means that more and more plants and factories are using a combination of technologies, Sensors connected to PLC or microcontrollers, Protocol converters to allow the Data to communicate across machines and include taking this data and using the Internet of Things, big data, analytics, and next-generation applications. This shift is already happening, and it's poised to change the manufacturing landscape completely.Industry 4.0 holds a lot of promise for businesses and organisations. One of the most powerful capabilities it offers is the ability to identify faults before they develop. This can lead to increased efficiency and productivity, as well as Optimised product development and supply chains. Additionally, it can improve health and safety in the workplace.Benefiting from better data management will require a big change for many organisations, which will need to start sharing data more freely between different departments that have traditionally operated in silos. This is new territory for the manufacturing industry, and while the potential rewards are great, there are also many challenges to overcome.Process improvement is something manufacturers often don’t know how much they need until they get started and notice the favorable outcomesMany manufacturers don't realise how much they need process improvement until they get started and see the positive results.Here at John Brooks we have fully embraced the new data-driven technology and have taken it a step further.

The DAIRY MGR is an all-in-one solution for automating CIP plant and vat wash routines.John Brooks specialises in technical innovation applying engineering ingenuity and existing technologies to create equipment that helps farmers to conserve energy and resources by optimising fluid pumping.We work for everyone who wants to ease their life by using advances in modern industrial automation engineering. We seek out opportunities to automate the manual or mechanical processes which in turn free up time and ensure more people can finish work sooner to spend more time at home.A perfect example of this would be the DAIRY MGR John Brooks have launched in 2021.The DAIRY MGR is an all-in-one solution for automating plant and vat wash routines for multiple vats, fault monitoring, and recording what was washed and storing these records securely. The best feature being it is compatible with the existing wash infrastructure in the dairy shed allowing to retrofit onto your existing equipment – washtub, pumps and pipes to both the milk pit and the milk vats.What Are the Challenges DAIRY MGR is solving?A Repeatable, Reliable and Automated Cleaning Routine with no standing around to ensure the next step in a wash process is executed.The New Zealand Food Safety Authority has strict guidelines related to cleaning in order to maintain maintaining milk quality standards. You can learn more about them here.There are a number of dangerous microorganisms present in the silage, animal bedding and soil that can infiltrate into the milk being delivered from the bovine. It is important to avoid as many of these dangerous microorganisms as possible especially on sensitive areas like the teats to ensure its cleanliness prior to milking.Even if only 1% of bacteria is left after thorough cleaning, they inevitably continue to grow and over time can contaminate milking machine clusters, milk receivers, milk pipelines and the bulk tank. Without a consistent, established cleaning routine, contamination will build up, especially in hard to reach areas, such as pipeline joints, that are hard to clean.The bacteria affect milk quality because it is breaking down the components in milk. That in turn reduces the shelf life of milk and milk products, and produces off flavours in cheeses and milk powders.That is why to ensure consistent high milk quality it is important to establish a process so that cleaning is done properly and all residues are removed in a timely manner and bacteria are destroyed.While there is an established plant clean in place process, there are number of challenges which have to be addressed. That is the reason why Dairy MGR was developed in the first place.Let’s explore the traditional established plant cleaning process to uncover these challenges, so that the advantages of Dairy MGR can be better understood in relation to these common challenges.Since bacteria is wide spread it can enter the plant from cows skin and the surrounding environment. There are many reasons why the milking environment is perfect for bacterial growth. That includes complex pipes architecture full of hard to reach area where residue can build up and create localised clusters feeding the bacteria growth.The end goal is to develop an effective plant cleaning vat routine which can control the presence of bacteria in the plant. That includes control over the quality of the water in order to achieve quality cleaning.Typical minimumal set of activites are required to be carried on a milking plant after every milking or milk vat pickup:Cold water rinse An acid wash An alkali wash at least twice weekly. An acid rinse after every alkali wash.It’s important to understand these three key factors affecting the qualtity of cleaning vat routine to in order to assess the effectivemess and limitations of this minimal set of required actions. TemperatureCold water is not suitable for effective water cleaning because it tends to redeposit the milk residues that needs to be removed and the "rewash" technique will not effectively remove residuals.At the same time when the water is too hot, it leads to breaking down detergents and damages seals and rubberware.The proper temperature to use in vat cleaning routine is 80-85°C when it exits the hot water cylinder. That provides sufficient temperature, which drops down as the water ‘travels’ through the pipes. Hot water wash should be dumped when water temperature reaches 55°C and below as this is considered to be no longer hot enough for effective cleaning of residue.The big question is: how do you control the water temperature without constantly monitoring it in person. The good news is that this water temperature can be monitored and controlled every time saving time and effort, including the need for physically being on site wth the help of DAIRY MGR. TimeIn order to achieve proper cleaning, hot water should contact the surface for at least 4 minutes. This time needs to be increased to a minimum of 7 minutes by re-circulation during an alkali wash.Pre-heating the plant can assist to achieve at least 5 minutes of contact time at needed temperature.For example, for a milking plant the recommendation is to use at least 10 litres of hot water per cluster to ensure sufficient contact time.For the bulk milk tank and all larger tanks,  it is recommended that hot water needs to be a minimum of 2% of the total capacity or 120 litres for 5,700 litre tanks or smaller.The question here is: who is controlling the time to make sure there is sufficient contact time with the surface? And again the good news are that DAIRY MGR can help to control the timing to ensure that hot water has a sufficient time contacting the surface so that residue that creates an ideal environment for bacteria growth can be removed and de-contaminated. Since each wash step is automated there is no downtime where traditionally the next step needs chemical or water added Chemical energyAcid detegrents are required to remove mineral deposits. While they can be used with cold water, they are more effective when used with hot water. Typically acid sanitisers include chemicals that also kill bacteria. They are designed to remain in the plant after washing in order to provide extended protection from bacteria. That is why acid detergents should be always be included in the final wash.Alkaline detergents are needed to remove blood, fat, and protein. If left inside the milk plant long enough, they can damage rubberware so it's important to neutralise the alkaline with an acid wash once they've done their job.  Acid wash helps to neutralise the alkali and complete the process of plant sanitization. The alkaline detergent is almost always chlorinated, or chlorine added.For both types of detergent, too much or too little is not a good option because striving for a greater quality wash and resuction of bacteria contamination, it’s important to aim for the right amount of chemicals used every time.You can only imaging that carefully measuring the right amount of detergent every day may be not the most interesting jobs in the farm. Fortunately today every farmer can choose to leave the job of careful measuring of the correct amount of chemicals required to DAIRY MGR, which was purposely designed to do this exact job right every time.The best thing is that the farmer can monitor what’s going on remotely in real time. This is important because as a responsible farm owner, every dairy farmer pride themselves in attention to detail especially when it comes to cleaniness and sanitisation of their plant.The whole food chain is someone reliant on every farmer delivering best quality milk and that is why Dairy MGR is designed to become a crucial part of everyday milk plant operation.Every farmer is now facing a dilemma, to continue dedicating time measuring chemicals and checking water temperature, or to be monitoring the process remotely from the comfort of their home. All Dairy MGR users need to do is to check their mobile phone remotely to learn that the cleaning routine kicks off with the correct water temperature, right amount of chemicals and is done correctly every time for both the plant and Vat.What is the benefit of DAIRY MGR for the dairy farmer in a nutshell?“For dairy farmer, DAIRY MGR can save 20-30min every single day by establishing control over the correct execution of plant & vat wash routine.”In layman terms, DAIRYMGR allows a farm worker to come home earlier to be with their family.How does it help you to come home earlier? Imagine this: Dairy MGR saves dairy farmers 20-30 minutes approximately every day, it is very reliable and accurate, it does not forget, doesn’t get tired, and initiates the correct wash cycle based on what is scheduled every day, with the right amount of chemicals, this allows the worker to multitask and ensure that you can get home earlier. Or a Full wash routine can be done on the milk vat after the tanker driver picks up the milk. Not just a rinse, so your ready to get straight in to milking particularly in the morning.DAIRYMGR is suitable for use in all types of dairy farms.
