Abstract

The invention relates to a mint drying method and mint drying equipment and belongs to the field of drying of products. According to the mint drying method and the mint drying equipment, the method is simple, i.e., the mint is soaked before being dried to remove dirty marks of the mint, and is preheated at the temperature of 25-26 DEG C before being dried at the same time to prevent the damage of the mint caused by non-uniform temperature before the drying of the mint; a controller is arranged in the equipment, the temperature during drying can be controlled well through the detection of a temperature sensor, and the temperature of a drying chamber and the drying time can be gradually controlled by the controller, so that the drying temperature is stable and uniform, the mint drying quality and the mint yield are improved, and the loss of nutritional ingredients in the mint can be avoided; an exhaust fan is arranged on the top of the equipment, so that the constant drying pressure in the drying equipment is guaranteed; meanwhile, the exhaustion speed of the exhaust fan can be adjusted according to the volume, and the drying efficiency and the drying quality are improved.

Description

technical field [0001] The invention relates to a mint drying method and drying equipment, belonging to the field of product drying. Background technique [0002] Mint, named "Yindancao" in the soil, is a Labiatae plant, that is, it belongs to other dry whole plants. It mostly grows beside rivers in mountain wetlands, and its rhizomes grow horizontally underground. It is an aromatic crop with special economic value. The whole plant is green and fragrant. The leaves are opposite, the flowers are small lavender, lip-shaped, and the small dark purple-brown fruits are formed after the flowers. Peppermint is one of the commonly used traditional Chinese medicines in China. It is a pungent and cool antipyretic medicine for sweating and treating influenza, headache, red eyes, body heat, sore throat and gums. [0003] In the mint production process, often due to improper temperature and time control in the drying step, the quality and nutritional content of the mint after drying h...
