An HTST milk pasteurizer, or high-temperature, short-time pasteurizer, treats milk by heating it to a high temperature and holding it at that temperature for a specified period to kill any harmful bacteria. This process also maintains the nutritional benefits of the milk. There are several types of HTST pasteurizers that dairy companies can choose from.
Direct Flow Pasteurizer
A direct flow pasteurizer uses a continuous flow of milk through heating and cooling sections. The milk is first heated using a heat exchanger, where hot water flows parallel to the milk, raising the milk's temperature. Then the milk is cooled down using cold water before going directly to the dairy company's processing lines. Because of the way it works, a direct flow pasteurizer can efficiently pasteurize large volumes of milk in a short time, making it a very popular choice for pasteurizing high volumes of milk. These systems are often associated with HTS Group and HTSW technologies, known for their reliable and efficient performance.
Buffer Tank Pasteurizer
A buffer tank pasteurizer uses a tank to store milk temporarily before or after it is pasteurized. The milk goes through the heating and cooling sections like in a direct flow pasteurizer, but instead of continuously flowing, the milk collects in the buffer tank for temporary storage. This kind of pasteurizer is great for when customers need to process different flavors or types of milk one after the other, as the tank can hold milk that has been processed through the pasteurizer already. Equipment from brands like Milk Pasteurizer Tunnel Pasteurizer and Milk Plate Pasteurizer offer advanced buffering solutions tailored for complex production needs.
Thermal Flare Pasteurizer
A thermal flare pasteurizer heats milk in a series of chambers in a batch process. First, the milk is heated up in one chamber, the milk moves to the next chamber to cool down, and the heat from the first chamber heats the next batch of milk. This process is great for pasteurizing smaller batches of milk quickly and efficiently. It works a little like the buffer tank pasteurizer but takes up much less space, too. Some manufacturers such as Watson Dairy Consulting HTST Pasteuriser have optimized this design for compactness without compromising efficiency.
Injection Pasteurizer
An injection pasteurizer uses steam to heat milk. First, the milk is pressurized to force it to absorb the heat from the steam, then it is heated in the pasteurizing chamber, and finally, it is cooled down in a heat exchanger before going out for processing or bottling. An injection pasteurizer can be very compact in size while still processing a large volume of milk. Leading models like the HT Spray Pasteurizer combine precision engineering with high throughput capabilities, ensuring consistent results across multiple production cycles.
