Abstract

The invention discloses a tea dryer which comprises a hopper used for containing to-be-dried tea, wherein the hopper is arranged on a frame; the hopper bottom of the hopper is composed of a screen; the bottom of the hopper is connected with a hot air pipe which is used for introducing hot air into the hopper so as to dry the tea; an air inlet hole is formed in a hopper wall at an opening of the hopper; the flow direction of the airflow at the air inlet hole inclines downwards, and the periphery of the hopper faces the interior of the hopper; and the air inlet hole is connected with an induced air component. According to the tea dryer with the structure, the possibility that tea dust escapes from the dryer can be effectively reduced, the operating environment of an operator is improved, and the service life of mechanical equipment is prolonged.

Description

Tea drier

Technical field

The present invention relates to Tea Production apparatus field, be specifically related to one and prepare Biluochun tea tea drier.

Background technology

Drying Titian is important operational sequence during green tea is produced, and generally in tea drier, completes, and utilizes hot blast to dry tealeaves.In actual mechanical process, because tealeaves is deposited in tea drier, easily there is the inequality of being heated in tealeaves.Therefore need operating personnel in drying course, constantly to stir tealeaves, and observe the oven dry degree of tealeaves; Tealeaves can produce a large amount of disconnected fannings and tea dirt stirring in process, these tea dirt can be overflowed to fly away at air and neutralize to fall to amassing in plant equipment along with hot blast from dryer, and operating personnel healthy damaged and affect the service life of plant equipment.

Summary of the invention

The object of the present invention is to provide one to prepare Biluochun tea tea drier, it can effectively address the above problem, and avoids tea dirt to overflow from dryer, improves the service life of operating personnel's working environment and prolonged mechanical equipment.

For achieving the above object, the present invention adopts following technical scheme to implement:

A kind of tea drier, it is characterized in that: comprise the hopper for holding tealeaves to be dried, hopper is arranged in frame, at the bottom of the bucket of hopper, be that screen cloth forms, the bottom of hopper with pass into the warm-air pipe that hot blast dries tealeaves to hopper inside and be connected, on the headwall of hopper oral area, be provided with air admission hole, the air flow direction of air inlet position is oblique lower and point to hopper inside by the periphery of hopper, and air admission hole is connected with air inducing assembly.

In such scheme by air admission hole being set on hopper outlet sidewall, air inlet position blows out the wind under oblique, can offset or alleviate like this hot blast upwards in hopper, thereby avoid hot blast that a large amount of tea dust lanes is gone out to tea drier, avoid tea dirt to overflow and fly away the healthy service life that damages and affect plant equipment on operating personnel in air.

Detailed description of the invention

In order to make objects and advantages of the present invention clearer, below in conjunction with embodiment, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.

The technical scheme that the present invention takes as shown in Figure 1, a kind of tea drier, comprise the hopper 11 for holding tealeaves to be dried, hopper 11 is arranged in frame 10, at the bottom of the bucket of hopper 11, be that screen cloth forms, the bottom of hopper 11 with pass into the warm-air pipe that hot blast dries tealeaves to hopper 11 inside and be connected, on the headwall of hopper 11 oral areas, be provided with air admission hole 11a, the air flow direction at air admission hole 11a place is oblique lower and point to hopper 11 inside by the periphery of hopper 11, and air admission hole 11a is connected with air inducing assembly.In the present invention, by exporting at hopper 11, air admission hole 11a is set on sidewall, air inducing assembly just can blow out the wind oblique from air admission hole 11a like this, for offsetting or alleviating in hopper 11 hot blast upwards, thereby the tea dirt of avoiding hot blast to carry in tealeaves is overflowed from tea drier, avoid tea dirt to fly away to the healthy service life that damages and affect plant equipment on operating personnel in air.

When practical operation, sidewall that can hopper 11 is set to sandwich, air admission hole 11a is arranged on the madial wall of hopper 11, and the wall chamber on hopper 11 sidewalls is connected with the bucket chamber of hopper 11 by air admission hole 11a, and wall chamber is connected with the air outlet of air inducing assembly.Hopper 11 can float and be arranged in frame 10, and the driving mechanism that drives hopper 11 to move back and forth in frame 10 is set in frame 10; Hopper 11 specifically can be a cylindrical bucket body, frame 10 can be a casing and forms, and warm-air pipe is arranged on box house, and air admission hole 11a offers along the circumferentially even interval of hopper 11, as the dryer for producing Pilochun (a green tea), it can arrange 6 in even interval on the madial wall in hopper 11 exits.Air admission hole 11a place is provided with baffle plate, baffle plate is connected with the adjusting part of regulation and control air admission hole 11a folding condition, adjusting part comprises an intelligent control switch 16, intelligent control switch 16 is arranged on distribution box 15, distribution box 15 is arranged on casing, control to adjust assembly by intelligent control switch 16 folding condition of each air admission hole 11a is regulated, coincide to heat required environment facies from different tealeaves in dryer or tealeaves different phase.

More preferred scheme is, warm-air pipe is constituted by inner and outer pipe 121,122, outer tube 122 is set in the periphery of inner tube 121, between inner and outer pipe 121,122, the folder chamber of clamping is connected with the wall chamber of hopper 11 sidewalls, the blower fan 14 that air inducing assembly is arranged by warm-air pipe inlet end forms, the air outlet of blower fan 14 respectively and the folder chamber of clamping between the tube chamber of inner tube 121 and inner and outer pipe 121,122 be connected, in the tube chamber of inner tube 121 inlet ends, be provided with the heating component 13 for heated air stream.Blower fan 14 exports Yi road air flow direction inner tube 121 tube chambers like this, after heating component 13 heating, the tealeaves in hopper 11 is carried out to drying and processing, another road air flow stream is blown into hopper 11 chamber of struggling against to hopper 11 wall chambeies through air admission hole 11a and plays the effect that stops tea dirt to escape, when concrete operations, the bottom of casing offers air inlet 101.

In a word, tea drier provided by the invention, it can effectively prevent the effusion of tea dirt, the time is cured in saving, reduces and manually stirs number of times, increases tealeaves degree of being heated evenly, improve tea leaf quality, the service life of lifting operation personnel's working environment and prolonged mechanical equipment.

The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
