Description

Feeding device of tea fermentation machine

Technical Field

The utility model relates to a tealeaves fermentation field, more specifically say, it relates to a feed arrangement of tealeaves fermentation machine.

Background

The fermentation of tea leaves is a series of reactions such as oxidation, hydrolysis and the like in the tea leaves under special environment. Of which the most important is the change in tea polyphenol substances promoted by the oxidation promoted by polyphenol oxidase and peroxidase. For example, the processing process of black tea has a 'fermentation' process, in the process, polyphenols in tea leaves generate theaflavin and thearubigins under the action of enzyme, and the substances form the color brightness and the chroma of the black tea soup of our black tea.

For example, chinese patent CN201220675161.7 discloses a tea leaf fermenting chamber, which comprises a chamber body, wherein the lower part of the chamber body is a cubic cavity, the upper part of the chamber body is a circular arc dome, a tea leaf fermenting frame is arranged in the center of the chamber body, an electric humidifier is arranged below the side wall of the chamber body, a ventilation window is opened on the side wall below the electric humidifier, and a window cover is covered on the ventilation window.

However, the sizes of leaves of tea leaves are greatly different from each other before the tea leaves are subjected to a fermentation process, and it is difficult to achieve a desired fermentation effect if the tea leaves are fermented together.

Therefore, a new solution is needed to solve this problem.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model aims to provide a feed arrangement of tealeaves fermentation machine, through the design of fan for tealeaves can be blown away by wind-force, and stops in different positions according to the difference of self weight, realizes the collection of tealeaves.

The above technical purpose of the present invention can be achieved by the following technical solutions: a feeding device of a tea fermentation machine comprises a rack, an elevator bucket connected to the rack, a screening cavity connected to the rack, and a fan communicated with the screening cavity, wherein a feeding hole is formed in the top of the screening cavity and is located right below the discharging position of the elevator bucket; the bottom of the screening cavity is provided with a plurality of discharge ports which are uniformly distributed along the working direction of the fan.

Tealeaves transports through the elevator bucket, and the elevator bucket will load after the predetermined height tealeaves is emptyd vertically downwards in the lifting, and tealeaves passes the feed inlet under the effect of gravity and falls into the screening chamber, and the fan is in operating condition this moment, because the tealeaves that the big tealeaves of leaf type is little is heavy, and the tender leaf is heavier than old leaf because of containing moisture many, and the distance that the tealeaves that weight is different was blown out by same fan is different to fall into different discharge gates respectively and realize collecting.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and examples.

Example (b): a feeding device of a tea fermentation machine is shown in figure 1 and comprises a rack 1, an elevator bucket 2 connected to the rack 1, a screening cavity 3 connected to the rack 1 and a fan 4 communicated with the screening cavity 3, wherein the top of the screening cavity 3 is connected with a top cover 32 through a bolt, a feeding hole 31 matched with the elevator bucket 2 is formed in the top cover 32, and the feeding hole 31 is positioned right below the discharging position of the elevator bucket 2; three discharge ports 33 are arranged at the bottom of the screening cavity 3, and the three discharge ports 33 are uniformly distributed along the working direction of the fan 4.

Tealeaves transports through elevator 2, and elevator 2 will load after the predetermined height vertical toppling over downwards at the tealeaves that the lifting was arrived, and tealeaves passes feed inlet 31 under the effect of gravity and falls into screening chamber 3, and fan 4 is in operating condition this moment, because the tealeaves that the big tealeaves of leaf type is little is heavy, the tender leaf is heavier than old leaf because of containing water is many, and the distance that the different tealeaves of weight were blown out by same fan 4 is different to fall into different discharge gates 33 respectively and realize collecting. After the collection, the leaves can be respectively collected from the angles of humidity and size through screening the leaves according to the size.

As shown in fig. 1 and 2, in order to make the blades blocked by the partition plates 34 and smoothly fall into the discharge port 33, a plurality of partition plates 34 are uniformly distributed at the bottom of the sieving chamber 3, a discharge chamber 36 is defined by the partition plates 34, and the discharge ports 33 are in one-to-one correspondence with the discharge chamber 36. Meanwhile, in order to prevent the partition 34 from blocking the wind direction of the fan, the partition 34 is provided below the fan 4.

In order to make the blades better pass through the discharging hole 33 for collection, the bottom of the discharging cavity 36 is obliquely arranged towards the central position, and the discharging hole 33 is positioned at the lowest part of the discharging cavity 36.

As shown in fig. 1 and 3, two fans 4 are provided, both fans 4 are connected to the sieving chamber 3, and a shock pad is provided between the sieving chamber 3 and the fans 4. In order to avoid that the fan 4 drives a large amount of dust to enter the screening chamber 3 together when in work, a dust screen 41 is arranged on the protective shell.

When the fan 4 works, in order to make the wind power received between the tea leaves similar, the discharge opening 21 of the lift hopper 2 is set to be a rectangle with a low width, and the air cooling fan 4 is arranged along the length direction of the discharge opening 21, so that the distance between the fallen tea leaves and the fan 4 is reduced as much as possible.

In order to keep the circulation of the gas in the splitting cavity, an air outlet 35 is arranged on one side of the screening cavity 3, which is far away from the fan 4, and a separation net is arranged at the air outlet 35, so that the tea leaves which are too light are prevented from floating out of the air outlet 35.

The working process is as follows: tea leaves are transported through the lifting bucket 2, the lifting bucket 2 lifts the loaded tea leaves to a preset height and then vertically and downwards topples the tea leaves, and the tea leaves fall into the screening cavity 3 through the feeding hole 31 under the action of gravity;

then the tea leaves are blown by the fan 4 and fall into different discharge holes 33 respectively according to different weights of the tea leaves to realize collection;

after the leaves are collected, the leaves can be respectively fermented from the angles of humidity and size through screening the leaves according to the size of the leaves.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection.
