Embodiment 1
[0021] (1) Pre-drying: Arrange the shiitake mushrooms evenly and neatly downwards according to the gills and put them into the oven. Control the temperature in the oven at 30°C and dry until the water content reaches 75%.
[0022] (2) Slow Su: Take the pre-dried shiitake mushrooms out of the oven and spread them out to dry for 1 hour.
[0023] (3) Drying: After raising the temperature in the oven to 50°C, place the shiitake mushrooms in step (2) in the oven, and raise the temperature in the oven to 53°C within 3 hours. After the top of the mushroom cap of the shiitake mushrooms is wrinkled, Then lower the temperature by 5°C, and dry at a constant temperature until the water content of the shiitake mushrooms is 30%.
[0024] (4) Moisture: Spread the shiitake mushrooms in step (3) to dry at room temperature for 3 hours.
[0025] (5) Shape setting: put the shiitake mushrooms in step (4) into an oven, control the temperature in the oven to 50° C., and then dry at a constant tempe...
