Small machine pasteurization

Types of small machine pasteurizations

A small machine pasteurization is a small pasteurization equipment for heat-treating dairy products like milk to kill harmful bacteria. Some common types of small machine pasteurizers are as follows:

• Batch Pasteurizers

  Small batch pasteurization machines are used to process milk in batches. They heat-treat a batch of milk at a specific temperature for a set period, then cool it down rapidly. Milk cooling down after heating is an important feature of batch pasteurizers. Milk is heated in a jacketed cooking vessel with internal temperature control. With less automation and smaller sizes, these batch pasteurizers are suitable for small-scale dairies or artisanal producers.

• HTST Pasteurizers

  HTST stands for High Temperature Short Time. HTST pasteurizers heat milk to a minimum of 72°C for 15 seconds. They use indirect heat exchangers to raise the temperature of the milk quickly. An integrated regeneration system also ensures that energy is used efficiently. Usually, HTST pasteurizers are part of larger dairy processing lines, but some small and mid-sized dairies also have them.

• Homogenizing Pasteurizers

  A homogenizing pasteurizer combines the processes of pasteurization and homogenization in one continuous unit. The process of homogenization breaks down fat molecules in milk so that they remain suspended evenly instead of floating to the top as cream does. These small machines heat milk to the pasteurization temperature, then cool it down rapidly before homogenizing it.

• HTP Sterilization

  A high-temperature processing or HTP pasteurizer uses indirect heating to heat-treat large volumes of liquid food at high temperatures. It is suitable for small-scale food and beverage production lines. HTP pasteurizers are available in fully automated models with touch-screen controls. They also have the energy recycling feature essential for saving energy resources while processing food and liquids.

Specifications and Maintenance of Small Pasteurization Machines

Specifications

Specifications of small-scale pasteurization machines may vary depending on the model and manufacture. However, they generally include the capacity, temperature control, heating system, and power source.

• Capacity: The capacity of a small pasteurization machine is usually measured in liters or gallons. The capacity ranges from 50 to 500 liters per hour.
• Temperature Control: The temperature control system enables the machine to heat the product to a precise temperature. Then, hold it for a specified period before cooling it down. This function is significant for ensuring effective pasteurization and product safety.
• Heating System: The heating system of a small pasteurization machine can either be indirect or direct. The indirect method uses heated water or steam in a heat exchanger to raise the temperature of the product. On the other hand, the direct method uses direct injection of steam into the product.
• Power Source: A small pasteurization machine can come in different power sources, such as electricity, diesel, natural gas, propane, and biomass. An electric pasteurization machine is usually connected directly to the power grid. With an electricity-powered machine, businesses can bypass the need for fuel storage and supply chains.

Maintenance

It is crucial to maintain small-scale pasteurization machines to ensure compliance and optimal performance. Several routine maintenance tasks can help ensure efficiency and safety.

• Cleaning: Regular cleaning is the most important part of maintaining a pasteurization machine. Cleaning helps prevent product contamination and remove any buildup or residue.
• Lubrication: The moving parts of the machine should always be lubricated to ensure smooth operation. Lubricating the moving parts helps reduce any possible wear and tear and minimize friction.
• Inspection: Routine inspection of the machine's components should be done regularly. With routine inspection, operators can quickly detect potential issues or damages and address them immediately.
• Training employees on proper handling and usage of the pasteurization machine is crucial. Training helps ensure safety and prevent unnecessary maintenance or machine breakdown.

Applications of small machine pasteurization

Small-scale pasteurization machines have several applications in different industries. One of the most popular applications is in the dairy industry for milk and cheese. They help eliminate pathogens and make the product safe for consumption. Little machines also preserve the flavor of milk and its nutritional value.

Smaller machines are also used in the juice industry. Fruit juices provide a suitable breeding ground for bacteria. Pasteurizing the juice eliminates these harmful bacteria and extends the shelf life. Small machines are also used to pasteurize liquid eggs and beer.

Besides food and beverages, small pasteurization machines are used in the pharmaceutical industry. They are used to ensure medicines, vaccines, and antibiotics are safe for use and free of harmful microorganisms. Liquid drugs are often sensitive, and heat treatment is used to ensure quality control.

Another industry that uses small pasteurization machines is the cosmetic and personal care industry. Products such as lotions and skin-whitening disinfectants are first pasteurized to eliminate any bacteria or germs that can harm the skin. Using a small machine also increases the shelf life of the products and enhances safety for the consumer.

How to Choose Small Machine Pasteurizations

Before buying any food pasteurizer, the following factors need to be considered:

• Capacity and Size

  Understand the capacity and size of the machine required. Consider the volume of liquid food that needs to be pasteurized per batch or hour. Find a pasteurizer that can handle the desired capacity to meet production requirements. Evaluate the available floor space and determine the compactness of the machine that accommodates business needs.

• Heating Method

  Consider the suitable heating method. Choose a pasteurizer with an efficient heat exchange system that minimizes energy consumption and maintains product quality. Assess the level of automation required. Consider a pasteurizer with automated controls and monitoring systems that ensure consistent pasteurization and simplify operators' tasks.

• Compliance with Food Safety Standards

  Ensure the pasteurization equipment complies with relevant food safety standards and regulations. Verify that the machine is manufactured using food-grade materials and designed for sanitary processing.

• Service and Support

  When it is necessary to replace or repair parts, the process should not be daunting. Go for machines that are widely used and therefore have an available service network. Check the parts availability and compare the service providers to find the best support.
