Problems solved by technology

The process steps are relatively complicated. It is necessary to put the dried semi-finished products into sacks, stack them at a height of 1-2 meters, and place them in a cool place for 10-15 days for stacking and moisturizing. This process not only has many steps, but also takes a long time to process and low efficiency. Moreover, special microwave drying is required, and microwave drying is required after cooking again, which consumes a lot of energy and costs high
