Microwave dryers are widely used in food processing. For example, the drying, sterilization and heating of chicken, duck, beef jerky, pork jerky and other products require microwave drying process. If foods such as beef jerky or fish fillets are not sterilized and dried using a microwave dryer, these foods will go bad within three or four days, thus affecting their sales and greatly damaging the economic benefits of the company. However, the food after microwave drying still maintains its original flavor and the shelf life can be extended to about 6 months.

Although microwaves have extremely strong penetrating power, they cannot penetrate packaging made of PET plastic, glass, paper, ceramics, etc., so this involves the issue of food packaging, because PET plastic or glass does not absorb microwaves and cannot It will generate heat. It is a good choice to use these to package food. It is hygienic and can avoid secondary pollution. Why not! In addition, it should be noted that since metal and aluminum foil can reflect microwaves without being penetrated, packaging materials cannot be made of metal or contain metal components.

Finally, I would like to remind everyone that when using a microwave dryer to process bottled food, the food in the package will heat up, causing the air pressure to increase. If it is completely sealed, the air pressure will be too high and the package will break. So, how to solve this problem? Method 1: Microwave sterilization and then seal quickly. Method 2: Place the sealed food in a pressure container and then use microwave sterilization. Method 3: After vacuum packaging, use microwave sterilization equipment to sterilize.
