Low-temperature hot air circulation vacuum combined drying method for chrysanthemum

Abstract

The invention belongs to the technical field of chrysanthemum processing, and particularly relates to a low-temperature hot air circulation vacuum combined drying method for chrysanthemum; the dryingequipment adopted by the drying method comprises a shell, a U-shaped plate, a hot blast stove, a vibration unit and a rotation unit; the bottom end of the shell is provided with a support and a discharge hole, and the inner wall of the shell is provided with a first hot air port; the hot blast stove is fixed on the outer side wall of the shell, and an output port of the hot blast stove is connected with the first hot air port; the vibration unit comprises a motor, a first rotating shaft and a rotating wheel; the motor is fixed on the outer side wall of the shell; the first rotating shaft transversely penetrates through the shell, and the end part of the first rotating shaft is fixedly connected with the output end of the motor; and the first rotating shaft is symmetrically sleeved with therotating wheels at positions close to the inner side wall of the shell, and the cross section of each rotating wheel is in a conch shape; and the chrysanthemum on the U-shaped plate are dried throughthe matching of the U-shaped plate, the hot blast stove, the vibration unit and the rotation unit.

Description

technical field [0001] The invention belongs to the technical field of chrysanthemum processing, in particular to a low-temperature hot air circulation vacuum combined drying method for chrysanthemums. Background technique [0002] Chrysanthemum, with flowers used as medicine, is a large number of commonly used traditional Chinese medicines, containing ingredients such as inulin adenine, choline, stachydrine, amino acids, acacia, borneol grade dihydroxyacetophenone. Traditional Chinese medicine believes that its nature is slightly cold, bitter and dry. It has the effects of nourishing the liver and improving eyesight, clearing wind and clearing heat, etc. It is mainly used to treat colds, fever, headache, tinnitus, red eyes and swelling, and sore throat; modern pharmacological research shows that the main components of chrysanthemum are volatile oil, flavonoids and amino acids, trace amounts Elements, etc., have multiple effects such as expanding coronary arteries, lowering...

AI Technical Summary

Problems solved by technology

[0003] In order to make up for the deficiencies in the prior art, if the drying temperature of the chrysanthemum is too high, a chemical reaction occurs in the chrysanthemum, and various chlorophylls and vitamins in the chrysanthemum are decomposed. As a result of the problem that chrysanthemums are easily damaged during subsequent storage and transportation, a method of combined drying of chrysanthemums with low-temperature hot air circulation and vacuum proposed by the present invention
