Abstract

The utility model discloses a novel tea screening device. According to the device, an upper screening net and a lower screening net are arranged in a screening machine; the screening machine is separated into an upper screening chamber, a middle screening chamber and a lower screening chamber through the upper and lower screening nets; the upper screening chamber and the lower screening chamber are respectively and correspondingly communicated with an upper discharge opening and a lower discharge opening; an upper discharging transmission belt and a lower discharging transmission belt are arranged in front of the upper and lower screening chambers and the upper and lower discharge openings which are correspondingly communicated with one another; the middle screening chamber is communicated with a winnowing chamber; and the winnowing chamber is communicated with the lower discharge opening and a middle discharge opening. The tea is selected by utilizing multi-section screening, and tea blocks are directly separated from tea dust; a winnowing machine is additionally arranged, and powder and other impurities in the refined tea are removed, so that the tea refining rate is greatly improved; and moreover, the novel tea screening device is high in continuity and high in degree of automation, and the labor intensity of a worker is effectively reduced.

Description

A kind of novel tea screening plant

Technical field

The utility model relates to tea making technology, refers in particular to a kind of tea screening device.

Background technology

Tea Processing is a numerous and diverse job, and each tealeaves monomer generally will be through the quality of tens roads even twenties procedure guarantee final finished.And an important indicator of evaluation tea quality is evenness.Evenness refers to the degree of consistency of a collection of tealeaves physics and chemistry shape.Which kind of teas all requires tealeaves evenness good.The main tea screening equipment that adopts carries out sifting sort to tealeaves at present, what generally adopt in the Tea Processing industry is the plane rotary strainer, but in the prior art, often only adopt a standard to screen tea raw material, so just cause and the meticulous inequality of tealeaves after screening, still occurs, the situation that impurity is more, such tea raw material is carrying out wind-force when sorting, single wind speed is wanted the tea raw material of alignment processing thickness inequality, so that the impuriting rate of equipment reduces greatly, also increased difficulty for the processing of later stage operation.

The utility model content

For the deficiencies in the prior art part, the utility model provides a kind of novel tea screening plant.This device has promoted the impurity elimination usefulness of tealeaves in Preliminary screening greatly by the combination of two sections screenings and selection by winnowing.

For achieving the above object, technical solutions of the utility model are:

A kind of novel tea screening plant is characterised in that: this device mainly is comprised of charging transport tape and a screening machine, is provided with upper and lower two-layer screen cloth in the described screening machine, and upper and lower floor screen cloth is separated into three screening of upper, middle and lower floor chamber with screening machine; Described upper and lower floor screening chamber respectively correspondence is communicated with upper and lower floor discharging opening, is provided with upper and lower floor discharging transport tape before the corresponding upper and lower floor screening chamber that is communicated with and the upper and lower floor discharging opening; Screening chamber, described middle level is communicated with a selection by winnowing chamber, and this selection by winnowing chamber is communicated with lower floor's discharging opening and a middle level discharging opening.

The usefulness of technique scheme is:

The utility model utilizes the multistage sub-sieve that tealeaves is sorted, the tealeaves of screening chamber, upper strata is the larger tea group of particle take epimere tea as the master, screening chamber, middle level is that stage casing tea is the selected tealeaves out that regulations require, and lower floor screening chamber is tea dust, and tea group, tea dust are directly separated.Set up winnowing machine and further remove foreign material such as bisque in the selected tealeaves, so that the refining rate of tealeaves has had great lifting.The utility model equipment continuity is strong, and automaticity is high, effectively reduces workman's labour intensity.

Description of drawings

Fig. 1 is the structural representation of the utility model tea screening device.

The specific embodiment

The utility model now is described in conjunction with the accompanying drawings and embodiments.

A kind of novel tea screening plant as shown in Figure 1, this device mainly is comprised of charging transport tape 1 and a screening machine.

Be provided with upper and lower two-

layer screen cloth

21,22 in the described screening machine, upper and lower

floor screen cloth

21,22 is separated into three screening of upper, middle and

lower floor chamber

31,32,33 with screening machine.

Described upper and lower

floor screening chamber

31,33 respectively correspondence is communicated with upper and lower floor discharging opening 51,53, the corresponding upper and lower floor that is communicated with

screen chamber

31,33 and upper and lower floor discharging opening 51,53 be provided with upper and lower floor discharging

transport tape

41,42 before.

Screening chamber, described middle level 32 is communicated with a selection by winnowing chamber 43, and this selection by winnowing chamber 43 is communicated with lower floor's discharging opening 53 and a middle level discharging opening 52.

As shown in Figure 1, tea raw material enters the upper strata screen cloth 21 of screening machine through charging transport tape 1, screen cloth 1 sieves tealeaves through behind the transverse judder, the tea group that particle is larger stays screening chamber 31, upper strata, the tealeaves that particle is less then enters screening chamber 32, middle level by upper strata screen cloth 21, comes on the lower screen 22.Lower screen 22 further sieves tealeaves through transverse judder again, and tiny tea dust is come lower floor screening chamber 33 by lower screen 22.Remove the selected tea of tea dust and then still stay screening chamber 32, middle level.

The tea group of screening chamber 31, upper strata is sent out via upper strata discharging opening 51 after 41 transmission of upper strata discharging transport tape, and tea group is collected and is used as him.The tea dust of lower floor screening chamber 33 is sent out via lower floor's discharging opening 53 after 42 transmission of lower floor's discharging transport tape.The selected tea of screening chamber 32, middle level directly falls into selection by winnowing chamber 43, through the wind-force effect tiny tea dust and bisque is blown out and fall into lower floor's discharging opening 53; The tealeaves of removing the selected mistake of tiny tea dust and bisque through selection by winnowing chamber 43 then falls into middle level discharging opening 52 and spreads out of, and namely gets the tealeaves that final cleaning is crossed.

Because lower floor's discharging opening 53 directly links to each other with selection by winnowing chamber 43, therefore should bind cloth bag or the polybag of collecting tea dust at discharging opening, prevent that tea dust from flying upward in the utility model.

Claims
