A special concentration device for propolis extract

Abstract

The invention discloses a concentration device special for a propolis extracting solution. The concentration device comprises a concentration tank, a vacuum freezing drier, a condenser, an alcohol recovery tank, a vacuum buffering tank and a vacuum pump, and is characterized by further comprising a concentrated solution temporarily-storing tank, a pressure sensor, a controllable valve and a programmable controller, and the concentrated solution temporarily-storing tank and the concentration tank are communicated with a vacuum pipeline so that the concentration tank can conduct continuous discharge in a negative pressure state; the pressure sensor is installed on the alcohol recovery tank, the controllable valve is installed on the vacuum pipeline, the programmable controller is connected with the pressure sensor, the controllable valve and the vacuum pump through signals, and the vacuum pump can be controlled by the programmable controller to intelligently work through dynamic pressure balance. The concentration device has the advantages that the vacuum pump can intelligently work, alcohol loss is greatly reduced, and most importantly, the propolis active ingredient loss is effectively reduced.

Description

technical field [0001] The invention relates to a concentration device, in particular to a special concentration device for propolis extract, and belongs to the field of mechanical technology. Background technique [0002] Propolis is a collection of animal and plant essences, containing more than 300 chemical components, including: aromatics, flavonoids, organic acids, terpenes, vitamins, enzymes, etc., with antioxidant, antibacterial, anti-inflammatory, antiviral, Liver protection and anti-cancer effects. As a natural substance that can improve health and improve physical fitness, propolis has attracted special attention. [0003] Most of the existing propolis extraction processes use alcohol as the extractant, and the concentration step in the process is a very critical step. The quality of the enrichment equipment design determines the quality of the product as well as the cost and efficiency of production. [0004] Existing propolis concentration equipment has many u...

AI Technical Summary

Problems solved by technology

[0005] (1) The vacuum pump works continuously for a long time, consumes a lot of power and wears out quickly;

[0006] (2) The temperature of the alcohol recovery tank is too high, a large amount of alcohol vapor is entrained and taken away, the loss is about 5-10%, and the alcohol loss is large;

[0007] (3) The alcohol recovery tank and the concentration tank can only discharge after returning to normal pressure, and cannot work continuously, which reduces the production efficiency;

[0008] (4) Part of the extract is heated continuously for a long time, and a large loss of active ingredients may reduce the potency of propolis
