It can be applied to the sterilization process of bagged snacks, meat products, desserts, pastries, soy products, flowers, edible mushrooms, whole grains, dried fruits, snack foods, food additives, puffed products and other foods.

Seven advantages of microwave sterilization equipment for box type food sterilization：
1. Short time and fast speed.
Box type microwave sterilization equipment transfers heat from the surface of an object to the interior through thermal conduction, convection, or radiation. It usually takes a long time for the interior of an object to reach the required dryness and sterilization temperature. The medium is composed of polar and non-polar molecules. Under the action of electromagnetic fields, these polar molecules change their orientation from their original random distribution state according to the polarity of the electric field. However, under the action of high-frequency electromagnetic fields, these orientations constantly change according to the frequency of the alternating electromagnetic field, which causes molecular motion and friction with each other, thereby generating heat. At this point, the field energy of the alternating electric field is converted into thermal energy in the medium, causing the temperature of the medium to continuously rise. So microwave heating is the loss of electric field energy by the dielectric material itself. Therefore, the microwave heating treatment time is greatly shortened, and at a certain power density, satisfactory results can usually be achieved in just a few seconds and minutes.
2. Low temperature drying sterilization to maintain nutrition.
The box type microwave sterilization equipment has dual sterilization functions of rapid heating with thermal effect and non thermal effect. Compared with traditional hot drying and sterilization, it can achieve the desired drying and sterilization effects at lower temperatures and in shorter times. The general sterilization temperature is 65-70 ℃. c. 75-80. c or 103-121. c、 Time of 3-8 minutes can preserve more nutrients and flavors such as color, aroma, taste, and shape. For example, vegetables treated with conventional heat can retain 46-50% of vitamin C, while microwave treatment can retain 60-90%, conventional heating can retain 58%, and microwave heating can retain 84%.
3. Save energy.
The microwave power conversion efficiency is high, generally above 70%. Microwave directly processes food, and the heating box itself does not heat up, without additional heat loss, which can save energy by 30-50%.
4. Thoroughly unify.
Traditional thermal drying and sterilization start from the surface of the material and then transfer to the interior of the material through thermal conduction. There is a temperature difference between the inside and outside of the material, and the consistency of drying and sterilization effects between the inside and outside is poor. In order to maintain flavor and shorten processing time, the internal temperature is often insufficient, which affects drying and sterilization effects. This phenomenon can be improved by increasing the processing temperature, but the quality of the color, aroma, taste, and shape on the surface of the product will decrease. Box type microwave sterilization equipment has penetrability, and its surface and interior work simultaneously, ensuring that the internal and external temperatures reach the required value together, thus achieving uniform and thorough drying and sterilization.
5. Easy to control and achieve automated production.
The microwave drying and sterilization equipment for food is easy to operate, control, and has no thermal inertia. It can be processed according to different food processing specifications, reducing the number of production operators and lowering production costs.
6. Simple equipment and advanced technology.
Compared with conventional sterilization, box type microwave sterilization equipment does not require boilers, pipeline systems, coal yards, and transportation vehicles, only basic conditions such as water and electricity, no special requirements for the workshop, less investment, and quick results.
7. Microwave equipment has no high temperature, helpless heat, does not generate heat itself, and has no thermal radiation. It can greatly improve working conditions, and the equipment structure is compact, saving factory space.
