Tremella drying process and tremella drying device

Abstract

The invention discloses a tremella drying process and a tremella drying device. A weighing device is arranged on a drying shelf in a drying room, a material tray for containing tremella is placed on the weighing device, a hot air device capable of blowing to the drying shelf from the upper direction, the lower direction, the left direction and the right direction is arranged, the temperature, the air direction and the air volume of the hot air device are adjustable, the water content of the tremella is calculated through the weight measured by the weighing device in real time, different drying control modes are selected according to the comparison result of the water content of the tremella and the control inflection point value, the hot air device is controlled to carry out drying in different combination modes, and drying is automatically stopped when the water content of the tremella reaches the set value. According to the tremella drying device, the water content is used as a control inflection point value in the drying process, compared with traditional timing drying, the device is more accurate, the uniformity is relatively consistent, the drying effect is better, the device can automatically end the drying process after the water content meets the requirement, the drying time can be saved, long-time drying can be avoided, and energy consumption can be reduced.

Description

technical field [0001] The invention relates to the technical field of drying agricultural products, in particular to a tremella drying process and a drying device thereof. Background technique [0002] The hot air drying technology of agricultural products is a main means of drying agricultural products at present. It is a method of blowing hot air into the drying chamber (drying box) and using convection to exchange moisture and heat with agricultural products, so as to achieve the drying of agricultural products. [0003] At present, the hot air convection method of the white fungus drying process in the market basically adopts the bottom-in and top-out method. When drying in this way, there will be a large difference in the moisture content of the upper and lower parts of the white fungus during the drying process, and the white fungus needs to be manually turned over during the drying process. Or prolong the drying time, need to increase the labor cost or lead to excess...

Problems solved by technology

The drying device disclosed by the former has a complex structure and high cost; the latter proposes to switch the wind direction at regular intervals, which is not quantified enough, especially in different seasons and different batches (such as differences in cleaning and soaking time), and the water content of fresh white fungus is different. , the timing control is not accurate enough; and the fixed side air drying is used, and the air volume during the drying process cannot be adjusted, which will easily lead to serious deformation of the white fungus during the drying process, resulting in poor quality of the white fungus and affecting sales.
