Microwave Pasteurization
Microwave can mutate proteins and physiologically active substances in bacteria, molds, eggs, etc., leading to delayed growth and death of microorganisms, and then achieving sterilization. Microwave sterilization temperature is lower than the conventional method. It is a new method to maintain food flavor and nutrition and prolong the shelf life. It is widely used in flour sterilization, insecticide, dehumidification and mold removal. The characteristics of microwave sterilization flour are reflected in the following aspects. 1. Fast sterilization. Microwave needn’t to heat the environment firstly, directly acts on the flour. And the temperature rises quickly, achieving the purpose of sterilization. In general, the sterilization temperature of the conventional method is 120 ° C - 130 ° C, the time is about 60 minutes. But microwave sterilization only needs about 1.5 to 3 minutes under 70 ° C - 105 ° C. Microwaves killing E. coli in flour take only 30 seconds. 2. Maintain nutrients and traditional flavor Microwave energy achieves bactericidal effects at lower temperature and shorter periods of time. The sterilized flour retains more nutrients and flavors such as color, aroma, taste and shape. 3. Saving energy Microwave acts directly on the flour, thus avoiding energy loss during heat transfer. In comparison, it can generally save 30%-50% energy. 4. Even and thorough Microwaves have selective properties, such as the ability to absorb more microwaves in areas with high moisture content, avoiding the consequences of breeding mold. Because the microwave has a penetrating effect, when the food is processed as a whole, the surface and the inside are simultaneously acted, so the sterilization is uniform and thorough. 5. Safe and harmless Microwave sterilization is a physical sterilization method that kills bacteria, molds and eggs without the addition of chemical preservatives. The sterilization process does not produce the residual toxicity or radioactive substances, and the sterilized flour is safe and harmless. 6. Easy to control The microwave sterilization equipment can be used immediately when opened. The operation is flexible and convenient, the microwave power is adjustable, and the operation is convenient. Microwave sterilization equipment can also be used for sterilization of food products, vegetables, dairy products, condiments, spices and other foods. It is the best choice for modern mechanized sterilization.Contact us/ [email protected]
