[0021] Example 1

[0022] See figure 1 :The preparation method of the dried extract of total glycosides of rehmannia glutinosa leaves of the present invention is to adjust the density to 1165kg / m 3 , Rehmannia glutinosa leaf total glycosides extract 1 is preheated to 30℃ in the feed tank 3, and the screw feed pump 4 is fed at a feed speed of 1.40kg / h, and the swing angle of the pendulum bar is 50° evenly through the distributor 5 Coated on the conveyor belt 2, and the conveyor belt 2 runs at a speed of 2.4m / h. Under vacuum conditions (-0.1~-0.01MPa), the Rehmannia glutinosa extract 1 moves through the first heating section 6 (temperature Is 75°C), the second heating section 7 (temperature is 75°C), and finally passes through the cooling section 8 (temperature is 35°C) to form a porous, loose cake-like dried substance 9. When the dried substance reaches the end of the equipment At this time, the stripper 10 is scraped off the conveyor belt 2, cut by the cutting device 11, and fal...

Abstract

The invention relates to a preparation method of a rehmannia leaf total glycoside extract dry product, which comprises the steps: firstly, the rehmannia leaf total glycoside extract is preheated in a charging stock tank and then uniformly coated on a running conveyor at the speed of 2-8m/h by a screw charging pump according to the 1-2.5kg/h charging speed through a distributing device; in the vacuum condition, the rehmannia leaf total glycoside moves and passes through a first heating section and a second heating section in sequence, and finally a cooling section to form porous and loosened caky dry product; when the dry product reaches the tail end of the device, the dry product is shaved off from the conveyor by a stripper, cut off by a cutting device and falls into a stranding cage pulverizer; and then the crushed dry product enters a product collecting tank by a discharging device. The obtained dry product is characterized by having low water content and good solubility, and being porous and loosened. Compared with a common vacuum oven drying method, the quality of the product obtained by the method is considerably increased and is beneficial to the follow-up preparation technology of the rehmannia leaf.

Description

Technical field [0001] The invention belongs to the technical field of dry extracts of traditional Chinese medicine, and specifically relates to a method for preparing a dried product of total glycosides of rehmannia glutinosa leaves. Background technique [0002] Rehmannia glutinosa leaves are dried leaves of Rehmannia glutinosa Libosch, a plant of the Scrophulariaceae family. Rehmannia glutinosa leaves are mainly produced in Huaiqing area of ​​Henan Province, and are also wild and cultivated in Shaanxi, Hebei and other places in my country. Modern pharmacological studies have shown that the main ingredient contained in Rehmannia glutinosa leaves is the total glycosides of rehmannia glutinosa leaves. The total glycosides of rehmannia glutinosa leaves have the effects of nourishing yin and invigorating the kidney, cooling blood and activating blood, and semen infusion to stop bleeding. It can be used to treat proteinuria, hematuria, and chronic glomerulonephritis; it belongs to ...
