Description

Tea screening device

Technical field

The present invention relates to the equipment in a kind of Tea Processing process, relate in particular to a kind of tea screening device.

Background technology

Tealeaves is deeply by a kind of drink liked of broad masses of the people, it possess natural, healthy, drink characteristics such as facilitating. Along with improving constantly of people's living standard, more and more people is constantly more high to the requirement of tealeaves. Therefore in the course of processing of tealeaves, screening just seems more and more important, can be weeded out by the foreign material in tealeaves by screening, it is possible to improve the quality of tealeaves significantly, also be conducive to the control to frying time and temperature in Tea Processing process simultaneously, be conducive to improving the quality of tealeaves.

The existing process being screened by tealeaves is all generally adopt artificial screening and mechanical grading, the many employing screening sieves of artificial screening, adopt multiple different screening sieve according to different demands, but are needing the requirement of screening too meticulous, needing several different screen clothes to screen, step comparatively bothers. mechanical grading many employings selection by winnowing, selection by winnowing utilizes tender tealeaves and light impurity, the weight of the non-tea type impurity such as sandstone, volume, the difference of shape and face size of keeping out the wind, respectively by the light pornographic movie in tealeaves under certain wind effect, the non-tea type impurity such as sandstone is separated, a large amount of use material loading shaking table or thrust impeller in existing tea-leaf wind selection device, the high-frequency vibration of material loading shaking table is easy to damage the blade of tealeaves, and thrust impeller by rotating, tealeaves stream is thrown to selection by winnowing district when material loading, and the stage entering material and applied thrust easily makes tealeaves sheet impaired. finally all there is a common shortcoming in above-mentioned two kinds of screening methods, is exactly due to the humidity of tealeaves, screening effect can be caused good not.

Summary of the invention

It is an object of the invention to provide a kind of tea screening device so that the breakneck acceleration of tealeaves is fast, effective.

Tea screening device in this scheme, include sieve body, described sieve becomes cylindrical, it is horizontally disposed with vertically, the closed at both ends of sieve, the bottom of sieve is provided with the husky net of sieve, sieve husky side off the net and it is provided with sandstone holder, sandstone holder becomes truncated cone-shaped, fix with screen side walls above it, screen side walls is divided into two parts along the midperpendicular running through axis, wherein a side-lower is tangentially provided with inverted T-shape feed-pipe, the upper opening of feed-pipe is charging opening, another opening is blast orifice, another side of screen side walls is set to screen cloth, screen cloth under be upwards divided into sieve aperture ladder increase three screening areas, each screening area arranged outside has the container shrouded on corresponding screen cloth, the bottom of container is provided with the 2nd husky net of sieve.

The tea screening device of this scheme is adopted to have following advantage: owing to the shape of sieve becomes anti-down cylindrical, tealeaves can rotate around screen side walls after entering below screen side walls with the wind, first due to heavier sandstone, can first fall into the sandstone holder sieving husky side off the net, then more a little bit smaller tealeaves due to wind surface less, can screen in the screening area that screen cloth bottom sieve aperture is less and enter corresponding container, then bigger tealeaves due to wind surface bigger, can continue upwards to move, then screen in the screening area of top, last bigger tealeaves can screen in last screening area, due to have employed a sieve, in screening process, tealeaves can be separated according to different sieve apertures automatically, do not need the power of other mechanical presses, so screening effect is better, and breakneck acceleration is compared to the screening mode of traditional multiple sieves, better effects if.

Preferably, the bottom on described container is also provided with discharge port, and the tealeaves owing to screening can be deposited in the bottom of container under gravity, is therefore that setting can so that container discharge be more easy like this.

Preferably, described feed-pipe is provided with nichrome wire near the position of blast orifice, and first the wind that such blast orifice is come in can be heated up by electric-heating-wire-heating, wind after intensification is when blowing tealeaves, it can be carried out certain drying simultaneously, thus avoid tealeaves to bond, improve screening effect further.

Preferably, being provided with the lid of a sealing above described charging opening, such setting can so that upon completion of the addition by sealing of lid charging opening, avoid unnecessary wind to spill from charging opening, be conducive to improving the screening effect of whole screening device.

Accompanying drawing explanation

Fig. 1 is the structural representation of embodiment of the present invention tea screening device.

Embodiment

Below by embodiment, the present invention is further detailed explanation:

Reference numeral in Figure of description comprises, the husky net 1 of sieve, sandstone holder 2, charging opening 3, blast orifice 4, little screening district 5, middle screening district 6, big screening district 7, container 8, discharge port 9, nichrome wire 10, lid 11.

The tea screening device of embodiment is as shown in Figure 1: include cylindrical metal sieve, sieve is horizontally disposed with vertically, edge and the end plate of sieve arrange metallic framework, the closed at both ends of sieve, the bottom of sieve has been bolted the husky net 1 of sieve, so that changing, it is provided with sandstone holder 2 below the husky net 1 of sieve, sandstone holder 2 one-tenth truncated cone-shaped, above sandstone holder 2, sidewall with sieve is bolted, the sidewall of sieve is divided into two parts along the midperpendicular running through axis, wherein lower right-hand side is tangentially provided with inverted T-shape feed-pipe, the upper opening of feed-pipe is charging opening 3, the lid 11 of a sealing it is provided with above charging opening, another opening is blast orifice 4, feed-pipe is provided with nichrome wire 10 near the position of blast orifice 4, the wind that such blast orifice is come in can first by nichrome wire 10 heat temperature raising, wind after intensification is when blowing tealeaves, can to tea-drying, tealeaves is avoided to bond. another side of screen side walls is set to screen cloth, screen cloth under be upwards divided into three screening areas that sieve aperture ladder increases, be respectively little screening district 5, middle screening district 6 and big screening district 7, little screening district 5, middle screening district 6 and big screening district 7 arranged outside have the container 8 shrouded on corresponding screen cloth, and the bottom of container 8 is provided with the 2nd husky net of sieve, and the bottom on container 8 is also provided with discharge port 9, so that the tealeaves discharging in container is more easy.

The tea screening device of this scheme is work like this: open lid 11, tealeaves to be screened is added from charging opening 3, open the blower fan of blast orifice, tealeaves enters with the wind below screen side walls, and rotate around screen side walls, first heavier sandstone, can first fall into the sandstone holder below the husky net 1 of sieve to be separated, then more a little bit smaller tealeaves due to wind surface less, can screen in the little screening district 5 that screen cloth bottom sieve aperture is less and enter corresponding container, then bigger tealeaves due to wind surface bigger, can continue upwards to move, then in top, sieve district 6 screen, residue tealeaves screens from big screening district 7.

Above-described is only embodiments of the invention, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this. Should be understood that; for a person skilled in the art, under the prerequisite not departing from present configuration, it is also possible to make some distortion and improvement; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.
