The Milk Business in Kenya: A Journey from Small Beginnings to Expansive Growth

The dairy industry in Kenya has been experiencing a significant transformation over the years. The advent of technology and innovative solutions has made it possible for entrepreneurs to venture into this business and achieve success. One of the key drivers of this business is the use of milk vending ATM machinesmilk pasteurizers, and milk cooler machines.

Kenya’s vibrant dairy sector is a cornerstone of the nation’s economy, providing a livelihood for countless farmers and ensuring a vital source of nutrition for families. But with a growing population and a rising demand for safe, high-quality milk, the industry needs innovative solutions to bridge the gap between farm and table. This is where milk vending ATMs, pasteurizers, and coolers are playing a game-changing role.

Imagine a world where access to fresh, affordable milk is no longer a daily struggle. Milk ATMs, essentially vending machines for chilled milk, are making this a reality across Kenya. These user-friendly machines dispense hygienically packaged milk directly from a refrigerated storage tank, ensuring its quality and extending its shelf life. Gone are the days of unreliable suppliers and inconsistent quality. Milk ATMs offer convenience for consumers and a reliable market for dairy farmers.

But what about the quality of the milk itself? Here’s where pasteurizers step in. Pasteurization is a heat treatment process that eliminates harmful bacteria from raw milk, making it safe for consumption.

Milk Coolers In Kenya, Things To Note And Where To Buy

Refrigeration is the single most important factor in maintaining the safety of milk. Milk Coolers are engineered to hold milk at temperatures below 40 degrees F which is ideal to protect milk’s quality. The cooler refrigerated milk is kept, the longer it lasts and the safer it will remain. As milk is allowed to warm, bacterial grow more rapidly and quality and safety are diminished. Properly refrigerated at temperatures below 40 degrees F, milk can be safely stored for about two weeks. Investing in a quality milk cooler is an investment in reliability and safety for employees and customers.

Once you’ve decided to purchase a milk cooler in Kenya, you need to choose your milk cooler – so what should you look for? Contact Tassmatt Agency Limited via +254 726410068 Here’s a short list that can help you narrow down your options to make the best decision for your milk cooling operation.

Understanding The Business Of Milk Chilling Machines In Kenya

A cooler is a scientifically designed mechanized machine wherein the power of outside air and water get utilized and this arrangement helps to maintain the target temperature at a constant level. As a result, the new-age machine is tailor-made to cool or heat substances, like milk, water, beverages, chemicals, etc. The machine serves a dual purpose, ideal for both cooling and heating.

This product is suitable for several industries, including dairy, food processing, and beverages.

As in this website, our focus is bulk milk cooler, let’s now shift our focus to the core subject.

The bulk milk chiller is a modular milk chilling system with the efficiency to cool milk from 35-degree C to 4-degree C. Its capacity may vary from one bulk milk chiller sellers in Kenya to another. Depending on the capacity of your dairy unit, you can choose the quantity of milk in the tank.

In case of special requirements, you are empowered to choose the capacity of the tank while placing special orders to manufacturers. There are a few leading Bulk milk cooler manufacturers who hold professional experience and expertise to manufacture tanks according to your dairy unit’s requirements.

How does the bulk milk cooler work in Kenya?

The machine is designed to remove heat from pasteurization and allows milk to cool down to an appropriate temperature. How does it impact? The cool temperature inside the chiller prevents the germination of bacteria and other microorganisms in milk, as a result, milk is protected from getting deteriorated.

This way shelf life of milk gets extended. With this exclusive system, dairy units have ample time to transport the product to different parts of the city and out of the city.

Chilling is a must as expressed in this section, as soon as the milk is received at the chilling centers. Otherwise, it will deteriorate owing to the germination of microbes.

Chilling has been considered as the most effective method to prevent the deterioration of milk, at the same time, this scientific process doesn’t affect the properties and nutritive value of milk. What an amazing blessing for all of us

STUDY; Facts On ATM Milk Segment In Kenya That Buyers Should Take Note

This article is from a study on the ATM milk market segment in Kenya; as outlined-out by Mr. Julis Mwaura of Tassmatt Agencies Limited, a leading milk ATM entrepreneur in Kenya and the following can be concluded:

    1. The Kenyan ATM milk market is growing but concentrated in a few towns, mainly in Nairobi County and neighbouring counties. However, there is a likely general trend of the market segment spreading to other urban areas if the sector is supported. The future potential of the ATM market segment is in targeting growing urban areas across the different counties and targeting all categories of income earners.
    2. The ATM milk market is expanding based on affordability of milk compared to pasteurized packaged milk and has the potential of expanding the formal milk market share beyond the current 30%. to more consumers.
    3. The flexibility in quantity of milk that is sold through milk ATM market segment has enabled consumers to access pasteurized and potentially safe milk thus contributes to household nutritional security. However, the finding indicate that some ATM milk does not meet the safety standards that comprise its value proposition to consumers and the industry.
    4. Consumer perceptions of milk quality were most important in making decisions about where to purchase ATM milk.
    5. The growth of the milk ATM market is linked to a shift from the initial reliance on imported technology towards more locally fabricated machines, which has reduced reduce the cost of the machines. This has stimulated the development and expansion of fabrication and manufacturing industrial cluster. However, this has led to unregulated fabrication that is compromising the quality of these Milk ATM machines in Kenya.
    6. The business ecosystem around the milk ATM retail market is expanding opportunities for job and business creation. In addition to fabrication of milk ATMs, other businesses that have emerged include milk pasteurizing, transportation, milk cooling systems, milk-handling equipment, servicing of the machines and sale of spare parts for milk ATMs in Kenya.
    7. Future growth of the ATM milk supply chain is anchored on
      i) enhancing design of cost-effective,locally fabricated, automated quality assured machines (including calibration, CIP and improvement in energy efficiency);
      ii) building consumer awareness on quality of ATM milk as pasteurized milk since some consumers perceive it as raw milk, and
      iii) a stronger, well-thought through regulatory framework that are more enabling and supportive of expanding milk ATMs quality-oriented market segment. The gaps in regulations for ATM machines and ATM milk (with regulations still in the draft stage) have implications for consumers and the regulator, in terms of food safety concerns as well as opportunistic behaviour of some fabricators, for example use of non-food-grade materials so machines are cheaper to make. With the relevant policy and regulatory framework being in limbo, there has been a rise of food safety issues in the ATM milk market segment.
    8. In terms of future outlook of the milk ATM market segment, the following can be concluded,based on scenarios built:
      • The business-as-usual scenario (status quo) projects the future potential growth of the ATM milk market segment by factors of 2.1–4.4 over the next 10 years.
      • The ATM milk market segment is likely to grow in the future, but it is sensitive to policy andmarket changes. It has the potential to encroach on the informal milk market segment,offering an alternative source of milk to consumers and resulting in maximum growth by afactor of 5.8 of ATM milk volume supplied over the next decade.


  • The milk ATM market segment has the potential to be a game changer in the process of formalization of the milk marketing sector if supported with relevant policy and regulations. GoK could fast-track policy and regulations to address unsafe operations and improve consumer confidence in the ATM milk product in order to utilize its potential, mainly linked to its price competitiveness, to be a game changer in the process of formalization of the milk marketing sector.
  • Despite ATM milk price competitiveness, food safety issues along the supply chain must be addressed. To enhance safe milk handling along the ATM milk supply chain the ATM business operators supported by Government of Kenya, consumer organisations and other stakeholder need to:o Enhance responsible behaviour along the supply chain through labelling and effective traceability systems, which will enhance consumer trust of pasteurized milk. This will require development and deployment of standard operating procedures at the different nodes of the supply chain.

    o Enhance capacity of the operators through a training programme. KDB can involve other parties to assist in this process, such as the public health department and consumer and food safety lobby organizations. This relates to development appropriate training curriculum and identifying effective means of delivery.

    o Work with other agencies, such as the Kenya Revenue Authority to enhance access to cheap food-grade materials, and with KEBS to development and ensure compliance with fabrication standards, to address the quality issues in ATM milk machines. This also calls for working with industry actors to build capacity for innovation in developing quality, affordable technology that meets the required standards.

    o Encourage private sector investment in expanding the ATM milk market, to develop a strong and robust chain that supplies pasteurized milk to ATM market retail outlets in additional towns.


  • Sensitizing consumers and assuring them of quality can grow the market prospect for ATM milk while building on its price competitiveness.
  • With the investments already made by operators, the upcoming regulations should facilitate improvements to the supply chain, for example a phased approach can be developed to stop the use of non-food-grade materials, to safeguard the interest of the investors and move to regulated machines. On the supply side, key enablers for the supply chain are enhancing growth of co-pasteurizers and building stronger linkages between milk ATM machine operators.
  • GoK could enable KDB to strengthen its capacity in terms of enforcement officers, data management systems, ATM milk traceability systems and appropriate systems for registering and monitoring ATMs.
  • Future growth depends on policy and market interventions in the sector by KDB that takes a less prescriptive approach but empowers the different operators along the chain . The interventions to facilitate growth in the milk ATM segment will come not only with finalizing the market and policy direction for the segment but also with meeting KDB capacity needs in terms of enforcement officers, data management systems, ATM milk traceability systems and appropriate systems for registering and monitoring ATMs. Further, increased investments in laboratory capacity and equipment as well as use of technology by KDB (e.g. using geographic information systems to map the milk ATMs and their suppliers) is required to enhance compliance rate.

Milk Cooler Tanks In Kenya, A Sure Bet To Your Milk Cleanliness And Quality

Farmers and Producers know, good milk quality depends on the correct cooling and system cleanliness. 0726410068

Milk cooling has come a long way in the past few decades in Kenya. From the early days of spring water passing through a stack of 10-gallon milk cans, getting milk cold as quickly as possible once it leaves the cow has always been a priority at any dairy farm.

This is for two primary reasons: to inhibit bacteria growth, thereby extending shelf life; and to ensure the milk’s taste, enhancing salability.

Although optimal bacterial growth conditions vary for different organisms, milk is an ideal medium for the growth of many types of bacteria. Milk temperature plays an important role in this growth. Many bacteria types prefer to grow at body temperature of 30ºC to 37ºC, and other psychrotrophic bacteria thrive at cooler temperatures of 4ºC to 10ºC.

To ensure the best milk quality, the goal is to keep these bacteria from making contact with the milk by means of quality herd health procedures, properly tuning milking equipment, ensuring the cleanliness of all milk product surface equipment and employing hygienic operator procedures. The next key defense is cooling the milk from the cow as quickly as possible to a holding temperature of 2ºC to 3ºC, as this will significantly reduce the growth rate of any bacteria present.

Milk cooler tanks have in the recent times became the option of choice across Kenya. These were prominently “open-top models” in capacities usually ranging from 250 to 5000 litres. The open top is preferred for two reasons: They are easier to dump milk into if you were to bring the milk to it in pails, and they are easier to wash with a manual brush. These coolers by tassmatt agencies limited are effective for cooling and particularly well matched for the milk delivery rates of milking systems.

As dairies grew in the late 1960s and 1970s, enclosed horizontal milk coolers became the normal offering. Sizes expanded, automatic wash was offered, and multiple evaporator plates allowed more cooling capacity to handle the higher milk flow rates that were becoming more commonplace. These tanks were able to be bulkheaded into existing milk rooms, which made them an attractive and cost-effective solution.

As dairies grew in the 1970s and 1980s, many started to apply “plate heat exchangers,” which allowed the cold well water used to water the cows to pass through the heat exchanger as a cooling medium to precool the milk from the cows before it entered the milk cooler. This remains a highly energy-efficient method to precool milk, improve overall long-term milk quality and reduce energy costs.

As years have passed, the enclosed horizontal milk cooler offerings have increased to sizes up through 30,000 litres. Many improvements in evaporator, refrigeration unit, wash system and control designs have improved efficiencies and provided many beneficial features.

Many dairies have grown and expanded to larger tank sizes and, in many instances, they use multiple tanks to allow multiple truckloads to be picked up at one time.

In-line cooling, often referred to as “instant cooling,” was developed in the late 1980s and applied to resolve these high milk flow rate cooling requirements. By using large-horsepower condensing units to cool a closed-circuit propylene-glycol solution, the capacity to cool large-volume milk flow became available. The chilled glycol solution was pumped through multiple sections of a high-flow plate heat exchanger.

As the milk was transferred from the milking parlour, it was first precooled with well water, then instant cooled immediately to the desired holding temperature as it passed through the chilled glycol heat transfer section. The instant cooling evolution was a great advancement toward the goal of cooling the milk to holding temperature as quickly as possible. Additionally, reaching cold milk holding temperature without constant milk cooler agitation provides milk quality advantages of reduced milk cell damage and elevated fatty-acids caused by extensive agitation and milk mishandling at warmer temperatures.

It should also be mentioned that instant cooling benefits for overall milk quality are not only associated with high-milk flow barns. Additionally, dairies appreciated having the milk instantly cooled to holding temperature before it entered the buffer tank and while the primary tank was being emptied and washed.

The ability to instant cool the milk also offered options such as pumping directly into transport trucks. This was seen as a significant advantage to large dairies, as often the capital cost of the truck was incurred by the hauler or milk receiver. Typically, the ongoing wash and maintenance costs were also passed on.

However, there were drawbacks with this type of system as well. First, the capacity of the cooling had to be sized to handle the peak milk flows rather than the average, as the milk was only passed through the plate heat exchanger once for a few seconds. Redundancy in condensing units was a must as well, for no opportunity to run at partial capacity was allowed. Additionally, in-line cooling, by its indirect nature (refrigerant to glycol to milk), could be approximately 20% less energy-efficient than traditional direct-expansion refrigeration in a milk cooler.

Scheduling trucks and drivers had their own headaches as well. The constant shuffling of trailers, evolving transportation laws and pushback from milk processors regarding load delivery times were often a hassle. This concern has only grown.

This trade-off has caused many to evaluate and decide to come back to on-farm storage with instant cooling. New advances in designs of vertical milk storage (silos) has included more capacity for direct-expansion cooling in these vessels, which can reduce the back-up redundancy that may be needed in the in-line cooling processes.

In some instances, peak milk flow loads can be handled by this extra cooling capacity now available on the newer silos. The capacity to hold a couple days of milk production provides significant insurance for truck failures, plant downtime, weather concerns, etc. Also, many expanding dairies recognize that a vertical silo installed on an exterior foundation and concrete slab can be much more cost-effective than incurring extensive construction costs to increase their milkhouse size and floor space to add more or larger horizontal milk coolers.

One of the most significant changes we see entering the marketplace today is in new control offerings for on-farm cooling and storage. Controls that can provide remote access to temperature and milk volume are now available. These have the option to send pickup alerts to the haulers, notifying them that the vessel is loaded to the proper level and at desired temperature.

They also provide the regulatory records for extended time and temperature recordings, eliminating the need for paper-and-ink recorders. Remote access is now available, allowing electronic milk volume level sensing; milk, wash and chiller glycol temperatures; refrigeration unit operating pressures and conditions; critical alarms; and historical data to be viewed in real time from any smartphone, tablet or computer with an internet connection.

It is safe to say that on-farm milk cooling, milk atm vending machine and milk pasteurizers has evolved over the past years, but as we look into the “future,” we can promise that it’s not over yet. end mark
