Grinding type air drying device for tea polyphenol processing

Abstract

The invention relates to the field of tea polyphenol production and processing, and discloses a grinding type air drying device for tea polyphenol processing. The grinding type air drying device comprises a shell, brackets, an air drying chamber, feeding holes and a discharging hole. A crushing disc of a conical structure is fixedly installed at the position, located at the bottom end of the feeding hole, in the shell, a crushing groove of an arc-shaped structure is formed in an outer ring of the bottom of the crushing disc, a set of rotating grooves are downwards formed in the top end of thecrushing disc, and a set of balls are connected into the rotating grooves in a rolling mode. A set of rolling discs of a conical structure are fixedly connected to the upper sides of the balls, a setof limiting rods are fixedly installed at the tops of the rolling discs, a set of rotating cavities with openings in the lower sides are formed in the upper sides of the limiting rods, two sets of pressing rods of the same structure are arranged on the left sides and the right sides of the rotating cavities, the air drying chamber is arranged in the position, below the crushing disc, of the shell,a vertical rotating cylinder is arranged in the middle of the air drying chamber, and an air heater is fixedly installed in the middle of the interior of the rotating cylinder.

Description

Technical field[0001]The present invention relates to the field of tea polyphenol production and processing, and is specifically a crushed air drying device for tea polyphenol processing.Background technique[0002]Tea polyphenols are generally known as polyphenols in tea, including xylools, glycosides, flavonoids, flavonols and phenolic acids. It is mainly a piece of yellow alcohol (catechin), and catechin accounts for 60-80%. Types of tea polyphenols, also known as tea tanning or tea, is one of the main components of tea color aroma, and is also one of the main components of health care function in tea.[0003]Tea polyphenols in the process of production, in order to facilitate subsequent use, it is necessary to perform corresponding drying treatment, but existing drying methods, typically operate using spray drying, but because tea polyphenols are powdery, Upon drying, if air is wet or in a problem, the problem occurs, the problem occurs, and is not conducive to subsequent drying, th...

AI Technical Summary

Problems solved by technology

[0003] During the production and processing of tea polyphenols, in order to facilitate subsequent use, it needs to be dried accordingly. However, the existing drying methods generally use spray drying. However, since tea polyphenols are in powder form, Before drying, if the air is humid or encounters moisture and the problem of agglomeration, once a block is formed, it is not conducive to the subsequent drying, thus affecting the drying efficiency. Therefore, it is necessary to design a device that can solve the above problems
