Problems solved by technology

[0003] Due to the current application of ginkgo, it is all used in traditional powder, and its powder is relatively coarse, with a particle size of 20-80 mesh (180-1000 microns). The ingredients cannot be released, so traditional powders have a large amount of oral administration, and the onset of action is slow, resulting in waste of resources, and the pollution of the ecological environment due to the discharge of undigested residues into the environment

Embodiment

[0020] Embodiment: the production of superfine ginkgo powder

[0021] Take 50 kilograms of whole herb (moisture content 8.5%), first select impurities, wash with cold water, dry in the air, chop into 3-5 cm long, and dry in a far-infrared oven at a temperature of 50-60°C for 30 minutes. Minutes later, quickly raise the temperature to 100°C, dry for 30 minutes, cool down naturally at normal temperature, store for 4 hours, the moisture content of the medicinal material is 2.6%, and then grind at normal temperature (20-35°C) in three stages (the first stage of mechanical crushing: The average particle size is about 800-1200 microns, the second stage of mechanical crushing: the average particle size is about 300-500 microns, and the third stage of airflow ultrafine grinding: the average particle size is below 10 microns) to obtain the ultrafine powder of hook kisses. Finally, in an environment with a relative humidity of less than 60% at 20±2°C, use high-density polyethylene packa...

Abstract

The invention discloses superfine gelsemium elegans benth powder and a preparation method and relates to a Chinese veterinary medicament, a veterinary natural plant feed additive and a preparation method. The main process comprises the following steps of: cutting selected gelsemium elegans benth into segments of between 3 and 5 centimeters; performing far infrared drying on the segments until the water content of the segments is less than 3 percent; smashing the dried segments at three stages comprising air stream superfine smashing for lowering the average grain size to be less than 10 microns; and removing oxygen and performing vacuum packing so as to obtain a superfine gelsemium elegans benth powder product. Compared with the conventional powder, the superfine gelsemium elegans benth powder of the invention has higher processing quality. The surface area of the superfine gelsemium elegans benth powder product is enlarged, the adsorption capacity is enhanced and the dissolving speed is increased; simultaneously, the broken sporoderm rate of plant cells is increased by superfine smashing, so that the superfine gelsemium elegans benth powder can be easily digested and absorbed by a livestock organism.

Description

technical field [0001] The invention relates to a Chinese veterinary drug and a natural plant feed additive for animals, in particular to a Chinese veterinary drug or a plant feed additive prepared from plant Chinese herbal medicines. Simultaneously, the present invention also relates to a preparation method of the ultrafine ginkgo powder. technical background [0002] Gelsemium elegans is the dried whole herb of Gelsemium elegans (Gardn. et champ.) Benth. Known ginkgo is crushed and sieved to make powder (edited by China Veterinary Pharmacopoeia Committee. Veterinary Pharmacopoeia of the People's Republic of China, 2000 edition, two [S], item 216.) for the treatment of pig dyspepsia, diarrhea and worm accumulation , due to the wide application in veterinary clinics, the reprinted Chinese Veterinary Pharmacopoeia is still recorded in the powdered (powdered) formulation of Gelkin (Chinese Veterinary Pharmacopoeia Committee. Veterinary Pharmacopoeia of the People's Republic o...
