Description
Technical Field
[0001] The utility model relates to the technical field of drying equipment, in particular to a drug raw material steam drying device. Background Art
[0002] The production process of the tablets that people take when they are sick is mainly to first soak the required medicinal materials in a solvent, dissolve the medicinal ingredients in the medicinal materials into the solvent, and then filter and separate the medicinal materials and the solvent. The solvent containing the medicinal ingredients is concentrated and purified into a paste or directly into powder, and then the powder is squeezed into tablets. In this way, the production of tablets is completed.
[0003] The concentration and purification in the production process of tablets is the baking process of the solvent. In this process, a purification tank or a concentration tank is used. The solvent is injected into the concentration tank, and the solvent is heated by a heating device, so that the solvent is continuously evaporated, thereby achieving drug concentration. Most common concentration tanks use electric heating plates for drying and heating, which easily causes the powder attached to the inner wall of the concentration tank to burn. Therefore, it is often necessary to continuously stir the medicine during the drying process to avoid this problem as much as possible. However, it should be noted that the medicine is taken out after it is dried into powder. Many designs are to set a conveying pipe at the bottom of the concentration tank, and a valve is provided in the conveying pipe. The powder is transported by opening and closing the valve. However, in this design, during the drying process, the part between the port of the conveying pipe and the valve will always be filled with medicine, and there will be no heating equipment around the conveying pipe. Therefore, this part of the medicine cannot be fully dried. It can only wait for the upper layer to gradually become powder, and the solvent in the lower layer will gradually penetrate into the upper layer. This causes this part of the powder to always have moisture residue and sticky, and it is not convenient to wash the concentration tank. After flushing, there will always be residue.
[0004] To this end, the utility model provides a drug raw material steam drying device, which improves the drying and concentration quality of the drug and makes it more convenient to take out and wash after the drug is powdered. Utility Model Content
