Filtering device for preparing colquhoumia root slice extract

Abstract

The invention discloses a filtering device for preparing a colquhoumia root piece extract. The device comprises a heating unit, an extrusion unit for extruding decocted colquhoumia root pieces, a lifting unit, an exhaust unit for pressure relief and exhaust, a rough filtration unit and a fine filtration unit, a first discharging port of the heating unit corresponds to a feeding port of the rough filtration unit, a second discharging port of the heating unit corresponds to a feeding port of the exhaust unit, a first feeding port of the heating unit corresponds to the outside, a second feeding port of the heating unit is communicated with a discharging port of the fine filtration unit, and a third feeding port of the heating unit is communicated with a discharging port of the exhaust unit. And a discharge port of the rough filtration unit corresponds to a feed port of the fine filtration unit.

Description

technical field [0001] The invention relates to extract preparation equipment, in particular to a filter device for preparing the extract of Huobahua root slices. Background technique [0002] Huobahuagen Tablet is a traditional Chinese medicine immunosuppressant made from the traditional Chinese medicine Huobahuagen as the main raw material. Because of its good anti-inflammatory and immunosuppressive effects, it has been widely used as a traditional Chinese medicine immunosuppressant in the treatment of various autoimmune diseases. Immune diseases, such as rheumatoid arthritis, lupus erythematosus, chronic nephritis, psoriasis, etc. At present, the method used for Huobahuagen tablets is water decoction and alcohol precipitation. After alcohol precipitation, the extract is filtered with a double filter, and the filter screen is silk cloth. This method cannot remove the turpentine and other mucilage in the extract, resulting in serious wall sticking of the filtrate during th...

AI Technical Summary

Problems solved by technology

This method cannot remove the turpentine and other mucilage in the extract, resulting in serious wall sticking of the filtrate during the concentration process, resulting in waste of materials and reduced efficiency. At the same time, the filtration is not fine, and the filtrate contains more impurities. It is difficult to granulate the paste, and it needs to be granulated twice. The hardness of the plain tablet is 3.5-4.0kg / cm 2 , fail to meet the process requirements, the product quality is unstable, and time-consuming and energy-consuming
