Plant polyphenol concentrating device

Abstract

The invention discloses a plant polyphenol concentrating device. The plant polyphenol concentrating device comprises a tank and a scraper mechanism arranged in the tank; the tank comprises a tank body, an upper cover and a lower cover; the tank body is of an inner hollow structure; a jacket used for a steam chamber is formed on the outer side of the tank body; the lower cover is connected with a lower opening of the tank body; a lower support plate supported on the lower cover is arranged at the lower opening of the tank body; liquid guiding holes, for guiding concentrated liquid into the lower cover, are formed in the lower support plate; and a support platform, for running fit with the lower end of a rotating shaft, is arranged on the lower support plate; the device is simple in structure and convenient to use; through the arrangement of the lower support plate and the support platform arranged on the lower support plate, the lower end of the rotating shaft can be matched with the support platform in a running fit manner, so that the lower end of the rotating shaft is less likely to sway during a working process, and a collision between scrapers and the inner wall of the tank isavoided, a concentration effect is ensured, the damage to the scrapers or the inner wall of the tank is reduced, and the service life is greatly prolonged.

Description

technical field [0001] The invention relates to the technical field of polyphenol production and concentration, in particular to a plant polyphenol concentration device. Background technique [0002] Plant polyphenols are the general term for polyhydric phenolic compounds, which widely exist in plants, participate in the process of plant growth and reproduction, bring colorful colors to plants, endow plants with sour, sweet, bitter and astringent tastes, and help plants defend against pathogens , pests and other hazards. Plant polyphenol protrusions generally go through the following steps: ester aqueous phase transfer extraction-concentration-refinement phase inversion-drying, and the concentration step is carried out by a concentrator. Concentrators for polyphenol production mostly use scraper-type concentrators, also known as scraper evaporators, which have heating steam jackets inside their shells and rotatable blades (scrapers) inside. Entering in the tangential direc...

AI Technical Summary

Problems solved by technology

In the existing scraper concentrator for polyphenol production, the scraper is driven by the rotating shaft, and the scraper will be resisted by the concentrated liquid during the rotation process, which requires a high connection strength between the scraper and the rotating shaft. Most of the existing scrapers are simply connected to the rotating shaft through connecting rods. The lower end of the rotating shaft is located in the tank without any support. In actual use, the rotating shaft that drives the scraper to rotate is easy to shake and affect the equipment. safe to use
