The two edible fungus and fruit and vegetable freeze-dried food production lines introduced by Jinwo Group, a provincial leading agricultural industrialization leading company, were put into operation in the modern agricultural park of Taling Town, Zhuanghe City. It is understood that this is the largest freeze-dried food production line in our city, and each production line can produce hundreds of tons of freeze-dried foods each year.

No refrigeration equipment is required. As long as it is sealed, it can be stored, transported, and sold at room temperature for a long period of time. It can remain unchanged for three to five years. Since this food has only 5% moisture content, it is of good quality and light weight, which can greatly reduce its operating costs. When fruits and vegetables are lyophilized and eaten, they can be rehydrated in a matter of minutes, just like fresh products. It is understood that the price of freeze-dried foods in the international market is 4-6 times that of ordinary hot-air drying dehydrated foods and is becoming a staple food for international trade. According to the person in charge of the Jinwo Group, the newly-established freeze-dried food production line can produce more than 400 tons of edible fungus and fruit and vegetable freeze-dried foods each year, mainly processed skim mushroom, which ac
