Background
In the process of the new shift of the demand of people on animal-derived food to quality, the veterinary drug residue in the known animal-derived food gradually becomes one of the main obstacles influencing the development of animal husbandry, so the demand of using green, safe and veterinary drug-free Chinese herbal medicine for animals is increasingly expanded. The traditional Chinese herbal medicine for veterinary use is time-consuming and labor-consuming, and can not meet the requirements of people on the Chinese herbal medicine for veterinary use completely. Therefore, the requirements on production equipment of the Chinese herbal medicine for livestock are increased, and various automatic crushing, mixing and extracting devices greatly improve the production and manufacturing efficiency of the Chinese herbal medicine for livestock and provide a foundation for the automatic intensive development of the animal husbandry.
The veterinary Chinese herbal medicines are generally divided into exterior-releasing medicines, heat-clearing medicines, purgative medicines, digestion-promoting medicines, tonifying medicines and the like according to the properties, the main functions and the taste of the veterinary Chinese herbal medicines, wherein the exterior-releasing medicines are one of the important branches of the veterinary Chinese herbal medicines according to the property and taste, and have the pungent taste and the functions of sweating and expelling muscles. Herba Ephedrae and ramulus Cinnamomi for pungent and warm exterior-releasing herbs, and herba Menthae and fructus Arctii for pungent and cool exterior-releasing herbs. When the extraction mode is utilized to extract the effective components in the ephedra and the mint, the ephedra and the mint are wet materials and do not need to be soaked, when the ephedra and the mint are mixed and crushed, the raw materials are easily adhered to a mixing and crushing device, the waste of the raw materials is caused, meanwhile, the ephedra, the mint and the like have large using amount in the Chinese herbal medicine for livestock, the ephedra, the mint and the like need to be leached for many times, and finally, leaching liquid is collected and purified. At present, the extraction or leaching steps of the existing Chinese herbal medicine for livestock are not generally finished in one step, but need to be carried out in multiple steps, and the raw material is often extruded between two working procedures, so that the solvent in the raw material is extruded as much as possible, and the extraction efficiency is improved. In most cases, the raw material is poured out for extrusion and then poured back into the extraction equipment, which is troublesome in practice.
In addition, a stirring device is required to be arranged in general extraction equipment in order to increase the contact area between the raw material and the solvent, but the solvent and a target substance are emulsified due to long-time stirring, so that the subsequent purification is difficult; however, if the stirring is not carried out, the materials are concentrated at the bottom, and the extraction efficiency is affected.
