The necessity of high power industrial microwave thawing equipment:

At present, most of the thawing equipment is 2450MHz 1kW, which is synthesized by multi-tube power. The efficiency is low, and the penetration depth of the meat package is shallow. Most of them need to be equipped with steam heating and thawing function before and after thawing. The process is complicated and the operation is inconvenient. However, the domestically produced 915MHz thawing equipment has a power of 20-40kW, the processing capacity of a single unit is limited, which is insufficient to meet the industrial production needs of the food industry.

LD1703 high power industrial microwave thawing equipment uses 915MHz microwave energy generator, which can synthesize power up to 150kW and process 10t per hour.It has high safety.The microwave thawing equipment that meets the demand for high-power production in industrial equipment.

Working principle of LD1703 high power industrial microwave thawing equipment:

When the microwave penetrates the food, the polar molecules such as water molecules in the food oscillate to generate inter-molecular friction. This friction occurs simultaneously in the millions of molecules inside the food, which generates heat inthe material. Since the microwave can penetrate into the frozen material in a large amount, the ice crystals are almost simultaneously heated and melted in the frozen block of the pork during the microwave thawing process.

During this period, the temperature difference between the thawed materials is small, and the difference in water pressure between the muscle fiber cells inside and outside is not large, so there is no obvious problem of juice loss caused by water movement.
