Description

A device that is used for traditional chinese medicine gardenia to adopt heat treatment

Technical Field

The invention relates to the field of traditional Chinese medicine processing, in particular to a hot water treatment and condition control device for picked traditional Chinese medicine gardenia fruits.

Background

Cape jasmine fruit (ZhiziGardenia jasminoides Ellis) alias name: gardenia jasminoides Ellis, Gardenia jasminoides Ellis and Cinobufagin are fruits of Gardenia jasminoides Ellis of Rubiaceae. The cultivation method is characterized in that the cultivation method grows in irrigated areas or forests of open fields, hills, valleys, hillsides and creeks at the altitude of 10-1500 meters, is produced in the south of Yangtze river basin in China, and is distributed in most provinces such as Jiangxi, Sichuan, Chongqing, Hunan and Fujian, wherein the cultivation area of Fujian, Jiangxi and Chuan Yu is the largest.

The fructus Gardeniae dried fruit is traditional Chinese medicine (whole fruit is used as medicine generally), has a longitudinal diameter of about 2.15-4.29cm and a transverse diameter of about 1.48-3.58cm, and has effects of protecting liver, promoting bile flow, lowering blood pressure, tranquilizing, stopping bleeding, and relieving swelling. Is used for treating icteric hepatitis, sprain, contusion, hypertension, diabetes and other diseases in traditional Chinese medicine clinic. Not only is used for synthesizing medicinal preparations for protecting nerves, relieving fatigue, preventing cardiovascular and cerebrovascular diseases and the like, but also is widely used for producing natural pigments.

The heat treatment is the most common treatment mode of the gardenia at present, and the reasonable hot water treatment for heat drying can better improve the content of main active ingredients (such as geniposide and crocin) in the fruits, and the general improvement rate is about 10 percent. 2015 edition of Chinese pharmacopoeia describes the heat treatment mode of gardenia by steaming to upper air or slightly scalding in boiling water, and related researches also show that the heat treatment mode can also influence the content increase rate of geniposide and crocin, such as steaming times, intermittent heat treatment, heat treatment time, temperature, drying mode and the like. The traditional heat treatment mode mainly adopts steaming in a steamer, the device is single, the temperature and the time cannot be accurately controlled, the steam manufacturing process is high along with energy consumption, the volume of equipment is limited, and the continuity and the consistency of treatment cannot be ensured.

1. the whole process only needs to add the gardenia fruits at the feeding port manually, collects the processed materials at the discharging port, and can add repeatedly according to the times of processing required to perform intermittent heat treatment.

2. The heating temperature and the processing time can be controlled, when the water temperature reaches the set temperature, the sensor responds, the singlechip controls the heater to be powered off, the water heating is stopped, the energy-saving purpose can be achieved, and when the water temperature is lower than the preset temperature by 0.3 ℃, the heater is powered on again. The conveying belt is influenced by the rotating speed of the motor, and the control of the processing time can be realized by changing the rotating speed gear of the motor through the single chip microcomputer.

3. The atomization spraying can quickly disperse the heat of the hot water to the surface of the gardenia fruit, thereby increasing the heat transfer area and the heat transfer efficiency, and reducing the speed of water evaporation and dissipation due to the fact that the atomization spraying is carried out at the temperature of below 100 ℃.

4. The waste water that washes after atomizing and spraying wet gardenia fruit gets into bottom of the organism through the filter plate under the action of gravity, remains partial heat, and heatable and cyclic utilization have reduced moisture and thermal loss simultaneously again.
