Microwave ripening technology has been widely used in whole grains in recent years. Mr. Zheng from weifang, shandong province wanted to ripen fresh corn by the effect of microwave.And at the same time in the vacuum has sterilization effect, which can be preserved for a long time to eat.At present, Mr. Zheng has established cooperative relations with many local supermarkets, and he wants to supply corn to supermarkets as a new product after it is matured in vacuum packaging.
According to the request of Mr. Zheng.We use vacuum package to pack fresh corn.Then the microwave equipment was used for curing experiments.It was found that the temperature should not increase too fast during the whole maturation process.If the temperature rises too fast, bags will swell to different degrees, which may eventually cause the vacuum bag to burst.In this way, the temperature was slowly raised during the experiment. The microwave power should be lowered if there was bagging phenomenon through the monitor, and the material should be reheated and matured after moderate cooling.
After several experiments, the microwave ripened fresh corn has a good taste and a crisp impression.At the same time, the double function is achieved, and the sterilizing effect is realized in the ripening process.Through the exploration of the experiment, the customization of this set of equipment should be increased technically on ordinary equipment, and a certain cooling system should be added.In this way, the cooling system will be opened when the bagging phenomenon happens again, and the raw material will be restored to its initial state at the fastest speed, which is convenient for the second curing and heating up.
As an experimental machine, Mr. Zheng plans to purchase 20KW equipment at first and upgrade the power of the equipment with the expansion of business at the later stage.
