Analysis of frozen food. The thermal conductivity of the water under the ice is approximately 4 times. Decrease in the rate of heat transfer between artful analysis of frozen food. Microwave to defrost food in small pieces quickly. But the thaw in food is rare in large frozen food (25 kg) are used in industrial processes. Since the water is heated up quickly when the ice began to melt large piece loaf rehydration occurs irregularly. Some of the food may be cooked while some may be appreciated. Therefore modified by reducing the power of the microwave and extend the period of recovery, or use a microwave resonant wave (pulse) to allow time for making a balance of temperature rise. Another application of microwaves is well Frost (defrost) food. Increasing the temperature from -20 ° C. To -3 ° C Which can be used for meat, cut into thin slices. Or lowering the temperature to temperatures below freezing over a bit easier. It is also used in the butter and fat accepted in the privatization did not have many advantages: 1. Faster is better as a lump lump Frost in 10 minutes instead of several days in a cool room. 2. requires less storage space. 3. There was no loss of weight of the ice melted, the yield (yield) and reduced the loss of nutritional value. 4. less labor requirements 5. A better sanitation since the packaging was good spring frost in the storage
system is good 6. Frost better. Thus improving the quality better.
