1. Drying application of edible fungi/powder products

1, home drying

Shiitake mushrooms are placed on the grill and sent to the drying room for baking. The large and thick layer with high water content should be placed on the upper layer, and the small and thin layer with low water content should be placed on the lower layer. Generally placed 8 to 10 layers. if

Placing too much, it is easy to make the upper, middle and lower layers of the material heating temperature is not uniform. The spacing of each layer should be 30 cm.

2. Temperature control

When the temperature of the drying room rises to 35℃, the mushroom can be dried in the room. When drying, you must first low temperature, and then gradually increase the temperature. Usually an hour to increase the temperature 1-3℃, the highest temperature should be controlled at 80-

85 ° C. Generally, it is required to bake at 35-40 ° C for 6 hours, at 40-60 ° C for 8-10 hours, and at 60 ° C for 2 hours. The higher the water content of shiitake mushrooms, the more time they need to bake at low temperatures

Long. If the baking has just begun, the temperature will rise suddenly, which will cause tissue water loss too fast, so that the mushroom cap is deformed and not rounded, the bacteria fold, the cap cracks, the color turns black, and the enzyme activity is destroyed

Shiitake mushrooms lose their original fragrance. Shiitake mushrooms into the drying room should be continuously baked until dry, heating can not be interrupted, the temperature can not be high and low, otherwise it will make shiitake mushrooms black color, quality decline.

3, humidity control

In the drying process of shiitake mushrooms, in addition to strictly controlling the heating temperature, timely drainage is also an important link. The basic principle of moisture removal two In the early stage of mushroom baking, when the temperature of the drying room is 35-40℃,

Moisture should be drained at full load; When the temperature rises to 40-60 ° C, the moisture can be discharged intermittently. After 60℃, you can not drain moisture. If the moisture is excessive, it is easy to make the mushroom light and white. If the baked mushrooms are soaked in water

The yellow color indicates that the moisture is not good, or the temperature is not enough, especially if the heat is stopped halfway, it is more likely to cause this phenomenon.

4. Quality inspection

When baking to 16-18 hours, you can open the drying room door to test whether the dried mushroom is qualified. During the test, use the material to press the junction between the cap and the stalk. If only traces are shown, it indicates that the drying is qualified

. If the feel is soft, the bacterial fold is also soft, it is necessary to continue drying, qualified drying products are characterized by: there is a special aroma of mushroom; Bacterial fold yellow, bacterial fold upright, complete, non-collapse; The mushroom body does not contain water

More than =13% of the mushroom retains its original shape, the cap is round and flat, and the natural color is maintained.

Second, the advantages of Nysta drying dehumidifier drying solution

(1) The automatic control system can choose the best drying temperature and humidity according to the process requirements of different products, which completely solves the long drying time, high temperature and high energy consumption existing in other drying methods

Many problems, with unparalleled desk characteristics.

(2) The use of high efficiency centrifugal fan, with strong wind, uniform air supply, low noise characteristics, material drying uniform and fast.

(3) No deformation, no cracking, no discoloration, no deterioration, no oxidation, thorough drying, good rehydration after drying, less loss of nutrients, long storage period, more effective protection

Color, aroma, taste, type and active composition of the dried substance.

(4) The unit is integrated design, and the pipeline and power supply can be used on site; Easy to operate, after setting the parameters, you can achieve automatic control, high reliability.

(5) Less investment, quick effect, can be used to transform old kilns, garages, etc., and can be migrated, save land area, etc., simple and convenient.
