Embodiment 1

[0016] In this example, first crush rehmannia and mugwort leaves into the coarsest powder of 20-80 meshes, and then mix the coarsest rehmannia powder and the coarsest mugwort leaf powder according to the weight ratio of the coarsest rehmannia glutinosa powder: the coarsest mugwort leaf powder 1:0.4 Mix, and then use ultra-fine pulverization equipment, the moisture content of Chinese herbal medicines is ≤ 6%, the medium volume filling rate is 60% to 80%, pulverize at room temperature for 35 minutes to become ultra-fine powder, the particle size of the powder in the ultra-fine powder is D 50 ≤35μm, D 90 ≤75μm, (D 50 ≤35μm means more than 50% of the Chinese herbal medicine particles with a particle size of ≤35μm, D 90 ≤75 μm means that the Chinese herbal medicine particles with particle size ≤75 μm reach more than 90%), and the cell wall breaking rate is not less than 90%.

Embodiment 2

[0018] In this example, first pulverize Ophiopogon japonicus and Artemisia argyi leaves into the coarsest powder of 20-80 meshes, and then make the coarsest Ophiopogon japonicus powder and the coarsest Artemisia argyi leaf powder in the weight ratio of 1:0.3 Mix, and then use ultra-fine pulverization equipment, the moisture content of Chinese herbal medicines is ≤ 6%, the medium volume filling rate is 60% to 80%, and pulverized at room temperature for 40 minutes to become ultra-fine powder, the particle size of the powder in the ultra-fine powder is D 50 ≤35μm, D 90 ≤75μm, the cell wall breaking rate is not less than 90%.

Embodiment 3

[0020] In this embodiment, the asparagus and mugwort leaves are first crushed into the coarsest powder of 20 to 80 meshes, and then the coarsest powder of asparagus and the coarsest powder of mugwort leaves are mixed according to the weight ratio of the coarsest powder of asparagus: the coarsest powder of mugwort leaves 1:0.5 Mix, and then use ultra-fine pulverization equipment, the moisture content of Chinese herbal medicines is ≤ 6%, the medium volume filling rate is 60% to 80%, pulverize at room temperature for 15 minutes to become ultra-fine powder, the particle size of the powder in the ultra-fine powder is D 50 ≤35μm, D 90 ≤75μm, the cell wall breaking rate is not less than 90%.

Abstract

The invention provides a process for machining plant type traditional Chinese medicine ultra-micro powder. The process comprises the following steps: firstly, crushing plant type traditional Chinese medicines which are rich in sugar substance, and folium artemisiae argyi into crudest powder of 20-80 meshes, wherein the plant type traditional Chinese medicines which are rich in sugar substance comprise dried rehamnnia roots, radix ophiopogonis, asparagus cochinchinensis, codonopsis pilosula, cistanche deserticola and polygonatum sibiricum; mixing the crudest powder of the traditional Chinese medicines and the crudest powder of folium artemisiae argyi in a weight ratio of (1:0.2)-(1:1), and further crushing for 15-45 minutes at the normal temperature by using ultra-micro crushing equipment with the medium volume filling rate of 60-80%, so as to obtain the ultra-micro powder, wherein the particle size D50 of the ultra-micro powder is less than or equal to 35 [mu]m, the particle size D90 of the ultra-micro powder is less than or equal to 75 [mu]m, and the cell-wall breaking ratio is not less than 90%. Due to the adoption of the process, the problems in the prior art that the traditional Chinese medicines which are rich in sugar substance can be bonded when being crushed, the particle sizes cannot meet the requirements, the uniformity is insufficient, the heavy metals exceed the standard, the production cost is high, and the like are solved.

Description

technical field [0001] The invention belongs to the technical field of preparation of superfine powder of traditional Chinese medicinal materials for veterinary use, and in particular relates to a processing technology of superfine powder of plant Chinese medicinal materials rich in carbohydrates. Background technique [0002] Plant-based Chinese medicinal materials are the synthesis of various natural Chinese herbal medicines after drying, and contain complex components such as fiber, lignin, starch and sugar. Through the ultra-fine crushing and wall breaking technology, the dry cell wall inside the plant-based Chinese medicinal materials can be crushed and used directly in the formula without decoction, which can greatly improve its bioavailability and effectively improve its medicinal value. Compared with the traditional treatment methods of traditional Chinese medicine, the superfine pulverization and wall-breaking technology can keep some active ingredients of Chinese m...
