Embodiment 1

[0021] see figure 1 , this embodiment will have a density of 1295kg / m 3 The kudzu root extract 1 (moisture content 40%) is preheated to 55 ℃ in feed tank 3 by screw feed pump 4 by the feeding speed of 6.0kg / h, is coated on conveyer belt by distributor 5 equably 2, the conveyor belt 2 runs at a speed of 6.0m / h, and the kudzu root extract moves through the heating section 6 (the temperature is 65° C.), the heating section 7 (the temperature is 60° C.), the heating section 8 ( temperature is 60° C.), and finally passes through the cooling section 9 (the temperature is 20° C.) to form a porous, loose cake-like dry matter 10 . When the dried material reaches the end of the equipment, it is scraped off from the conveyor belt 2 by the peeler 11, cut off by the cutting device 12, and then falls into the cage type pulverizer 13, and the pulverized dry material enters the product collection through the discharge device 14 tank 15. After analysis, the prepared kudzu root extract dried...

Embodiment 2

[0023] The kudzu root extract density of this embodiment is 1362kg / m 3 (moisture content 35%), other operating conditions are with embodiment 1, and the moisture content of prepared kudzu root extract dry matter is 3.14%, and drying speed is 3.76kg / h. Production capacity is increased compared with embodiment 1.

Embodiment 3

[0025] The temperature of the heating section 6 of this embodiment is 80°C, the temperature of the heating section 7 is 75°C, the temperature of the heating section 8 is 65°C, the feed rate is 8.0kg / h, and other operating conditions are the same as in Example 1. The moisture content of the paste dried product was 2.96%, and the drying rate was 4.53kg / h.

Abstract

The invention discloses a new drying process for kudzu root extract of Chinese medicine. Kudzu root extract (1) is preheated in a charging stock tank (3) and evenly coated on a conveyer belt (2) by a screw charging pump (4) through a stock distributing gear (5). Under the vacuum condition, the kudzu root extract (1) moves and passes through heating sections (6) (7) (8) in sequence as along with the conveyer belt (2), and goes through a cooling section (9) at last, forming a porous, loose and cake-like dry substance. By adopting the method, the kudzu root is dried step by step under the vacuumconditions; the whole drying process is mild and short in time. The obtained dry substance is a porous and loose medium, which has the advantages of light color, low water content and good solubility. Operating environment is totally enclosed to prevent people from the cross infection between people and material, which meets GMP requirement. Compared with the drying method of a vacuum baking ovenoperated by hand, the whole drying process realizes continuously full automatic control and greatly reduces labor intensity and improves production efficiency.

Description

technical field [0001] The invention belongs to the technical field of drying traditional Chinese medicinal extracts, and in particular relates to a new drying process for traditional Chinese medicinal kudzu root extracts. Background technique [0002] Pueraria lobata is the dried root of Pueraria lobata or Puerariathomsonii Benth, a leguminous plant. It has the effects of relieving muscle and reducing fever, promoting body fluid, promoting rash, promoting yang and relieving diarrhea. It is used for exogenous fever, headache, stiff neck and back, and thirst. The drying of kudzu root extract is one of the important steps in the production process of kudzu root preparation, which has a great influence on product quality. At present, the drying methods of kudzu root extract mainly include vacuum oven drying and spray drying. Patent 01113473.9, the title of the invention is "A Preparation Method of Compound Chinese Medicine Extract", which involves drying kudzu root extract by ...
