Microwave defrosting refers to the method of defrosting frozen food under the action of certain frequency electromagnetic wave. Compared with traditional natural defrosting, water immersion or water drenching defrosting, it has prominent advantages of short time, uniform internal and external heat, reduced meat loss, no loss of nutrients, clean environment and high product hygiene standards.
Frozen chicken microwave defrosting machine is a kind of special equipment for defrosting frozen food. The microwave defrosting equipment is composed of a tunnel-type microwave generator box and a conveyor belt.In order to adapt to different sizes of meat defrosting required speed, the speed of transmission using frequency control.
Advantages of frozen chicken microwave defroster:
- Refrigeration system of frozen chicken microwave defrosting machine: fully automatic control of refrigeration temperature, ensure the quality of frozen products, keep the product fresh, efficient and safe.
- Circulating air system of frozen chicken microwave defrosting equipment: it is made of 304 stainless steel.The fan adopts high-quality axial flow fan, which is safe and stable to ensure food hygiene requirements.
- PLC automatic control system of frozen chicken microwave defrosting machine: humanized control, high automation precision, accurate temperature curve display, automatic control, a variety of defrosting methods.
- Microwave frozen chicken defrosting machinetakes less time and has good product quality. Take defrosting tuna as an example, it can be defrosted to cut with a knife, microwave defrosting only takes 28.5 minutes, while air defrosting takes 16 hours, with no loss of nutrients,low water loss rate, maintain the original color of the product.
- Microwave defrosting equipment for frozen chicken has germicidal effect, inhibits the growth of microorganisms, and defrosting food is not contaminated.
- The microwave frozen chicken defrosting mechanical device occupies a small area, saving site investment and labor costs.
- Microwave frozen chicken defrosting machine can realize continuous production, which will not generate high temperature, reduce shutdown and cooling time, and greatly improve production efficiency.

Examples of traditional defrosting processes:
1.Air defrosting
Move frozen meat to defrost room, heat exchange defrost by air medium and frozen meat.
This is an original defrosting method with low cost and convenient operation, but the defrosting speed is slow.
Defrosting in high temperature , there is a big temperature difference between the surface and the inside of the meat, which is likely to cause discoloration, drying, dust contamination, breeding bacteria, etc. In defrosting with air, certain wind speed, temperature, humidity and other factors must be considered to ensure product quality.
2.Liquid defrosting
Liquid defrosting method is mainly the method of water immersion or spray.
High water consumption,makes part of the protein and extract lose, change color, fragrance. The water temperature is 10 ℃, defrosting 20 h; The water temperature is 20 ℃, defrosting 10 ~ 11 h. And the meat that finished defrost, because of the wet surface,need to put in the air temperature around 1 ℃ under the condition of dry.
Working principle of frozen chicken microwave defroster:
Frozen chicken microwave defrosting machine heating frozen goods rapidly which at -42 to -18 degrees , so that both inside and outside of the frozen defrosting at the same time to -2 degrees Celsius state without water dripping.
Using microwave heating, low energy consumption, small temperature difference between inside and outside,the material is basically intact during defrosting, defrosting speed, can effectively keep the original flavor, color and nutrition of food.
At the same time has a strong bactericidal effect. With the continuous development of microwave technology, we believe that microwave defrosting devices and microwave drying equipment and other advanced microwave equipment will be preferred in factory processing machinery and equipment.
