Intelligent drying system for shiitake mushrooms

Abstract

The invention discloses an intelligent drying system for shiitake mushrooms. The intelligent drying system adopts full-computer numerical display and numerical control. The intelligent drying system comprises a control portion and a circulating drying portion, wherein the control portion comprises a frequency converter and a circulating frequency-conversion fan; the connected three-phase electricity of the frequency converter is used as an input end; an output end of the frequency converter is connected with the circulating frequency-conversion fan; the air quantity of the circulating frequency-conversion fan is adjusted according to the set instructions; the circulating drying portion comprises a cooling heat pipe, a heat pump evaporator, a heating heat pipe, a main condenser, a compressor, an auxiliary condenser, a thermal expansion valve and a solenoid valve; and the auxiliary condenser is controlled by the solenoid valve to be started when the temperature is not high enough and disabled when the temperature is high enough. According to the intelligent drying system of shiitake mushrooms, the problem of uneven heated temperature of the shiitake mushrooms during drying can be solved, through full numerical control operation, the labor cost is reduced, and more energy and more electricity are saved.

Description

technical field [0001] The invention relates to the technical field of edible fungus drying, in particular to an intelligent drying system for shiitake mushrooms. Background technique [0002] Shiitake mushroom is the second largest edible fungus in the world and one of the special products in my country. It is known as "mountain delicacy" among the people. It is a fungus that grows on wood. Delicious taste, refreshing aroma, rich nutrition. Shiitake mushrooms are rich in vitamin B group, iron, potassium, vitamin D, sweet in taste and flat in nature. Indications loss of appetite, lack of energy and fatigue. Mushrooms are known as the king of delicacies, and they are high-protein, low-fat nutritional and health food. Usually fresh shiitake mushrooms are not easy to store. Therefore, after the shiitake mushrooms are grown, they need to be dried before being transported and sold, which can extend the shelf life of the shiitake mushrooms. [0003] In the mushroom drying equ...

Problems solved by technology

[0003] In the mushroom drying equipment in the prior art, it is difficult for users to set the air outlet temperature according to their own needs, resulting in uneven heating temperature. It often occurs that several layers have been dried, and some layers are still wet, which is easy to cause Partial deterioration of the shiitake mushrooms occurs during the drying process. In addition, the old fan used in the equipment is noisy
