Impurity removal system for mesona chinensis liquid

Abstract

The invention discloses an impurity removal system for a mesona chinensis liquid. The system comprises a filtering device arranged between a boiling extraction process and a concentration process; the filtering device is communicated with an extraction pot and a liquid storage tank through a liquid inlet main pipe and a liquid outlet main pipe respectively, and composed of multiple reverse parallel conical cylinders (No.1, No.2, No.3,...,No.N); an impurity removal port is arranged at the bottom conical tail of each conical cylinder; the liquid inlet of each conical cylinder is arranged on the cylindrical wall at the upper part of the conical cylinder and tangentially communicated with a liquid inlet pipe; the liquid outlet of each conical cylinder is arranged at the top of the conical cylinder and connected with a liquid outlet pipe; each liquid inlet pipe is communicated in parallel with the liquid inlet main pipe, and each liquid outlet pipe is communicated in parallel with the liquid outlet main pipe; and each liquid inlet pipe and each liquid outlet pipe are respectively provided with a control valve. According to the invention, because the combined conical cylinders are used as a filtering device, the filtered impurities can be discharged anytime so as to avoid the influence on the normal conveying of the mesona chinensis liquid between the previous process and the next process and guarantee the normal production.

Description

(1) Technical field: [0001] The invention relates to a liquid filtration system, in particular to a system for removing impurities of grass jelly liquid in the preparation process of grass jelly. (two) background technology: [0002] Grass jelly (Mesona chinensis), also known as jelly grass and fairy grass, is an important medicinal and edible plant resource. The stems and leaves are collected and dried to become dried grass jelly for later use. The dry grass jelly contains about 70% carbohydrates, rich in polysaccharides, pigments, blood pressure-lowering factors ursolic acid, oleanolic acid, fragrant tree essence and sitosterol, sitosterol, sitosterol glucose and a variety of anti-inflammatory agents. Trace elements beneficial to the human body have health effects such as improving human immunity, lowering blood pressure, lowering blood sugar and inhibiting tumors. [0003] The total extracts of grass jelly are collectively called grass jelly, which can be used as raw ma...

Problems solved by technology

[0004] Filtration and impurity removal of the extract is an important link in the production process of jelly jelly powder, which determines the coherent production between the boiling process and the concentration process. Traditional filtration and impurity removal uses sieve filtration. Due to the unique gel performance of jelly jelly liquid, The viscosity of the liquid is high, and the flow rate of the sieve is already low. In addition, the sediment and branches and leaves left in the grass jelly extract (residual in the grass washing process) will gradually block the mesh, resulting in a further decrease in the liquid flow of the jelly grass. To meet the supply required by the next process, it is necessary to stop production and clean the screen from time to time, resulting in interruption of the process and seriously affecting production
