In the processing of the food and agricultural products, we would always meet some questions of killing enzyme. For example, the flour made from grain, whose active enzyme is very strong. We should kill them. Overwise the bread used the flour have bad taste. It also has problems if the flour use in other aspects, such as adhesives, intensifier, filler. The common methods of killing enzyme is that heat the flour to 64℃. This will lead to the loss of water in flour and need to dispose again. But only need a few seconds if use microwave. It can kill a large number of microorganisms in flour and couldn’t influence the characteristic of the flour. For example the slaking of the sea cucumber. The traditional method is by dehydrating and flooding sostenuto. The nutrition of the sea cucumber will be lost. Now the sea cucumber just need to be cooked at low temperature. Microwave sterilization is the result of the thermal effect and biological effect. Thermal effect is to make the protein denaturation and kill microorganisms.
Microwave heating is a new method of heating. It’s no pollution, no energy consumption. It can heat equably and needn’t heat conduction. The materials warm inside and outside at the same time. The speed of drying is quick. This machine can adjust the speed by itself. Adjust power according to temperature automatically. Adjust the heating time combining the temperature automatically. Increase power combining speed automatically. It is suitable for large quantities of nuts. Such as walnuts, chestnuts,almonds, pistachios, walnuts, sunflower seeds, watermelon seeds, pumpkin seeds, peanuts, hazelnuts, torreya grandis,nuts,etc.
