Application of freeze dryer in food industry
Freeze-dried staple foodConvenient staple foods mainly include instant noodles, instant rice, convenient porridge, clams, dumplings, buns and so on.
At present, the drying methods for producing convenient staple foods mainly include hot air drying, microwave drying, microwave hot air drying, vacuum freeze drying and the like.
Many scholars have compared these drying methods to find that the convenient staple food produced by vacuum freeze-drying technology has a good taste, the nutrients remain intact, the rehydration is good, the drying effect is obviously superior to other drying methods, and it is especially suitable for nutrition due to low temperature operation. Strengthen the production of food.
The fast-food dumplings through freeze-drying can be soaked in hot water of 90~95°C for 8~10min, and can maintain the original shape and structure of the dumplings, and have better instant dissolution.
