A small pasteurizer typically consists of a stainless steel tank with an electric or steam-powered heating element and a temperature control system. The liquid product is pumped into the tank and heated to the required temperature. Once the set temperature is reached, the product is held at that temperature for the required time to ensure that all microorganisms are destroyed. The pasteurized product is then cooled and pumped out of the tank for further processing or packaging.
The basic components of a small pasteurizer include a heating element, a temperature sensor, and a cooling system. The liquid to be pasteurized is placed in a container, which is then placed inside the pasteurizer. The heating element heats the liquid to a predetermined temperature, typically between 60-85°C (140-185°F), which is maintained for a specific time period to kill any bacteria present in the liquid. The temperature sensor ensures that the correct temperature is reached and maintained throughout the pasteurization process.
Once the pasteurization process is complete, the cooling system is activated to rapidly cool the liquid to a safe temperature for storage. The liquid can then be bottled or transferred to another container for storage. Small pasteurizers can vary in size and capacity, with some models capable of processing as little as 5-10 liters of liquid at a time, while others may be able to handle larger volumes. They are commonly used by small-scale dairy farmers, home brewers, and juice producers who want to ensure the safety and quality of their products.
