300 milk pasteurizer

Types of 300 milk pasteurizers

A 300 milk pasteurizer is used to heat milk and kill bacteria and pathogens in dairy products. There are several types of milk pasteurizers available on the market.

• Batch Pasteurizers

  The batch pasteurizer heats a specific batch of milk. The milk is heated to the required pasteurization temperatures and then cooled down to temperatures below 4°C. This process can take anywhere between 30 and 60 minutes, depending on the capacity of the pasteurizer. The main advantage of this type of pasteurizer is that it maintains the nutritional value of the milk. It is also easy to operate and control. Some pasteurizers also have the option of batch homogenization. In this case, the cream on the milk is emulsified and mixed back into the milk.

• Continuous Flow Pasteurizers

  In a continuous flow pasteurizer, milk is heated and then cooled as a constant flow stream. This pasteurizer uses plate heat exchangers to heat the milk to the required temperature and cool it down using either direct or indirect methods. The same process as in the batch pasteurizer occurs. Because of the constant flow in the continuous flow pasteurizer, larger quantities of milk can be processed. The equipment is also more compact in size. However, the seasonal fluctuations in milk availability make this equipment suitable for large-scale dairy industries where all refrigerants are used all year round. The capital and operating cost of the continuous flow pasteurizer will be much higher compared to the batch.

• Direct and Indirect UHT Pasteurization

  UHT (Ultra High Temperature) pasteurizers extrude milk at high temperatures (125°C to 140°C) for a few seconds using plate heat exchangers. The milk is then cooled rapidly. Some UHT pasteurizers can also homogenize milk. Once the milk is heated, it is filled into aseptic containers. An advantage of the UHT process is that it extends the shelf life of the milk and dairy products.

• HTST Milk Pasteurizer

  A high-temperature short-time pasteurizer heats milk to at least 72°C for 15 seconds. It has a similar working mechanism as the UHT pasteurizer but not at ultra-high temperatures. The HTST pasteurizer is more commonly used in the dairy industry. Once milk is heated to the desired temperature, it is cooled down to 4°C and stored at this temperature until it is used.

• Microflavor Pasteurizer

  This type of pasteurizer is mostly used in cheese manufacturing. It is a batch pasteurizer that cools milk by circulating chilled water or brine through a double wall.

• Homogenizer Milk Pasteurizer

  A homogenizer pasteurizer breaks down fat molecules in milk into smaller particles. This process ensures that the milk is distributed uniformly. Some pasteurizers have the homogenization feature, while other appliances have it separately.

The type of 300-liter milk pasteurizer chosen will depend on various factors, such as the capacity of the appliance required, whether the appliance is to be used in a dairy farm or dairy processing facility, the budget, the required features, whether the appliance is to be used for other dairy products, and the technical expertise of the operators. Depending on these preferences, all kinds of milk pasteurizer appliances can be found on the market.

Specification and maintenance of 300 milk pasteurizers

• Capacity: The capacity is the maximum amount of milk that the pasteurizer can process in one batch. A 300 milk pasteurizer indicates that the machine can handle up to 300 liters of milk per batch.

• Quality assurance:300 milk pasteurizers must comply with internationally recognized standards and regulations for dairy processing equipment, such as ISO certification.

Regular maintenance and cleaning of the milk pasteurizer is essential to ensure its proper functioning, consistent performance, and prolonged lifespan.

• Daily cleaning and sanitization:Always adhere to the pasteurizer manufacturer's cleaning and sanitization instructions. Before cleaning and sanitizing, ensure that the milk pasteurizer is switched off and disconnected from the power supply. After processing the dairy product, thoroughly clean and sanitize all parts of the pasteurizer that come into contact with milk or dairy products, including tanks, pipes, valves, heat exchangers, and homogenizers.
• Routine maintenance：Create a maintenance schedule for the milk pasteurizer that includes tasks such as inspection, lubrication, replacement of wearing parts, and calibration of instruments. Adhere to the schedule to ensure the equipment remains in optimal condition. Regularly inspect critical components of the milk pasteurizer, such as heating elements, temperature sensors, homogenizers, pumps, and valves, for signs of wear, damage, or leaks. Perform necessary maintenance operations like cleaning, tightening, adjusting, or replacing parts to ensure proper functioning.
• Safety precautions：Always disconnect the power supply and water pipes of the milk pasteurizer before carrying out any maintenance or repair operations. Carefully read the instruction manuals for the tools and replacement parts used. Ensure that the tools and replacement parts are of the correct type and are suitable for the milk pasteurizer model. Ensure the working environment is well-ventilated, with sufficient lighting to prevent accidental injuries or operational errors.
