Embodiment 1

[0013] Referring to Fig. 1, the preparation method of the dried product of Erigeron breviscapine extract of the present invention is that the density is 1210Kg / m 3 The breviscapine extract 1 is preheated to 45°C in the feed tank 3, and then is evenly coated on the conveyor belt 2 by the screw feed pump 4 at a feed rate of 4kg / h through the distributor 5, and the conveyor belt 2 Run at a speed of 6m / h, and the extract of Erigeron breviscapus moves sequentially along with the conveyor belt 2 through heating section one 6 (temperature is 80°C), heating section two 7 (temperature is 75°C), heating section three 8 (temperature is 70°C), and finally passes through the cooling section 9 (at a temperature of 20°C), forming a porous, loose cake-like dry matter 10, which is scraped off the conveyor belt 2 by the peeler 11 when the dry matter reaches the end of the equipment , fall into the cage pulverizer 13 after being cut off by the cutting device 12, and the dried matter after the pu...

Embodiment 2

[0015] See Figure 1, the density is 1250Kg / m 3 The breviscapine extract 1 is preheated to 45°C in the feed tank 3, and then is evenly coated on the conveyor belt 2 by the screw feed pump 4 at a feed rate of 7kg / h through the distributor 5, and the conveyor belt 2 Running at a speed of 7 m / h, the extract of Erigeron breviscapus passes through three heating sections (operating temperature is the same as that in Example 1) successively along with the conveyor belt 2 to form a porous, loose cake-like dry matter. When the dry matter reaches the end of the equipment, it is scraped off from the conveyor belt 2 by the stripper 11, cut off by the cutting device 12, and falls into the cage pulverizer 13, and the crushed dry matter enters the product collection tank 15 through the discharge device 14 . After analysis, the moisture content of the dried extract of Erigeron breviscapus prepared was 3.22%, and the drying speed was 3.75kg / h.

Embodiment 3

[0017] See Figure 1, the density is 1250Kg / m 3 The breviscapine extract 1 is preheated to 45°C in the feed tank 3, and then is evenly coated on the conveyor belt 2 by the screw feed pump 4 at a feed rate of 10kg / h through the distributor 5, and the conveyor belt 2 Running at a speed of 9.2m / h, the extract of Erigeron breviscapus passes through three heating sections (operating temperature is the same as that in Example 1) successively along with the conveyor belt 2 to form a porous, loose cake-like dry matter. When the dry matter reaches the end of the equipment, it is scraped off from the conveyor belt 2 by the stripper 11, cut off by the cutting device 12, and falls into the cage pulverizer 13, and the crushed dry matter enters the product collection tank 15 through the discharge device 14 . After analysis, the prepared dry product of Erigeron breviscapus extract has a moisture content of 5.802%, which has exceeded the specified range of a moisture content of less than 4%. ...

Abstract

The invention discloses a porous Erigeron brevsicapus extract dry substance and its preparation method. The method comprises pre-heating Erigeron brevsicapus extract in feed tank, spreading uniformly on a convey belt with a distributor, delivering to pass through each heating regions and a cooling region sequentially to form porous, loosened and dried substance, scrapping the substance off the convey belt, cutting off with a cutting apparatus, pulverizing, and collecting. The whole process is performed under vacuum and mild conditions for a short period of time. The produced dried extract has porous and loosened texture, light color, low water content and good dissolubility. The inventive drying method helps to increase the product quality, as compared with the existing vacuum-oven drying method.

Description

technical field [0001] The invention belongs to the technical field of drying traditional Chinese medicine extracts, and relates to a method for preparing porous and loose dried scutellaria scutellaria extract. The dried scutellaria scutellaria extract obtained by the method has light color, low water content, porous and loose, With good solubility, the product quality is greatly improved compared with the ordinary vacuum oven drying method. Background technique [0002] Erigeron breviscapine is the whole herb of Erigeron breviscapine (vant) HangMass, a plant of the genus Erigeron breviscapine (vant) HangMass, commonly known as Erigeron breviscapine. Its medicinal preparation has the functions of promoting blood circulation, removing blood stasis, dredging collaterals and relieving pain. It can be used to treat stroke hemiplegia, coronary heart disease, angina pectoris and myocardial infarction. . Extraction drying is one of the important steps in the production process of ...
