Dried Lentinus edodes

The drying technology of Lentinus edodes is very important, which plays a key role in the shape, color and flavor of Lentinus edodes. The drying equipment must be dried with a dryer to ensure the quality, and the local drying should be completely eliminated.

When drying, the size and thickness should be separated, the dry and wet should be separated, the mushroom stalk should be placed flat on the drying screen, the mushrooms with small and thick water content should be placed on the bottom layer, and the mushrooms with large water content, thin and small should be placed on the upper layer. Fresh mushrooms with high water content can be dried in the drying room after drying in the sun for 1-2 hours.

① preliminary drying period: the drying temperature should not be too high or too low, and it should be controlled at 35 ℃. At this time, the inlet and exhaust holes should all be opened, the return hole should be closed, and the drying time should be 3-4 hours. Generally, the temperature rises by 1-2 ℃ per hour, and the temperature should gradually rise to about 40 ℃.

② constant speed drying period: after drying for 4-5 hours, the temperature will gradually rise to about 50 ℃, rising about 2 ℃ per hour, and the intake and exhaust holes will be closed by 1/3. This stage is generally dried for 3-4 hours.

③ drying period: when drying for 8-9 hours, the temperature should gradually rise to 55-60 ℃. At this time, the intake and exhaust holes should be closed by 1/2, and the return hole should be opened by 1/2. This stage is generally dried for 1-2 hours.

④ complete drying period: in the last hour, the temperature should be controlled at 60-65 ℃, all the inlet and exhaust vents are closed, and the return holes are all opened, so that the hot air circulates up and down, which can ensure that the bacteria are yellowish and increase the aroma.

Pay attention to five points when drying:

The heating and cooling of ① should not be too fast, but only increase or decrease gradually, otherwise the wrinkling of mushroom cover will affect the quality.

The highest temperature of ② should not exceed 65 ℃, otherwise it is easy to scorch.

③ mushrooms with white or grayish white noodles can be laid flat on the mushroom sieve, spray water evenly on the mushroom noodles (not on the bacterial folds) with a clean sprayer, then put them into the drying room, close the doors and windows for 30 minutes, and then dry normally. If you can't do it at one time, you can do it 2-3 times so that the mushroom noodles are of the same color.

If ④ is not screened, it must be carried out quickly after 5 hours.

Lentinus edodes dried by ⑤ should be packed in time, dried at low temperature and kept away from light.
