Abstract

The utility model relates to a novel tea drier which utilizes hot air to make the tea dried and comprises a drier base, a cylindrical tea baking room, a sieve outlet and a sieve supporting plate. The tea sieves on which the tea is laid are overlapped in the tea baking room layer by layer and an electric lifting device is used for controlling the elevating of the sieve supporting plate. Through the push fit of the sieve seat supporting plates positioned on the periphery of the sieve supporting plate and the movable sieve seats positioned at the lower part of the tea baking room, the tea sieves are supported out from the lower part of the tea baking room layer by layer. The tea does not need to be stirred in the process of baking. Therefore, the shape of the baked tea is ideal, the tea does not have broken tea and the quality of the tea is good. The tea drier has the advantages of simple structure, convenient and agile operation and good combination property.

Description

Tea drier

The utility model belongs to the oven dry machinery that utilizes hot blast to make tea-drying.

The present tea drier that uses, normally allow tealeaves by transmission or stir mobile mode and in the hot blast chamber, pass through, tealeaves stirs frequently by going into to going out the process intermediate frequency, cause tealeaves form erratic variation, profile is undesirable, and tealeaves makes fannings increase in stirring process again, and tealeaves some tealeaves in moving process blocks, can not withdraw from fully outside the machine, then may in the baking chamber, produce the smell of burning; A kind of drum type brake tea drier that occurs on the present market, whole sieve tealeaves descends step by step, drying course need not to stir tealeaves, its sieve seat supporting plate and under-chassis seat and the peripheral inboard uniform seesaw type portable screen seat in the junction surface in roasting teahouse, complex structure, holder sieve plate lowering or hoisting gear is the hand lever lowering or hoisting gear then, is unfavorable for using.

The purpose of this utility model is the problem that exists at existing tea drier, proposes a kind of reasonable in design, adopts the novel tea dryer of Motorized lift device.

This is newly with the novel cylindrical shape roasting teahouse that comprises, under-chassis seat rest by the bottom, one deck connects one deck and stacks in order to the tea of lay tealeaves sieve in the roasting teahouse, separate by separation frame between the tea sieve, the sidewall in roasting teahouse has a hot air inlet, being right after roasting bottom, teahouse is screening mouth, screening mouth is provided with a supporting plate, this holder sieve plate is supported by a central shaft, connection one makes the device of its oscilaltion on the central shaft, the portable screen seat that is no less than 3 in under-chassis seat and the peripheral inboard uniform setting in the junction surface in roasting teahouse sieves with carriage tea, periphery setting at the holder sieve plate forms the sieve seat supporting plate that ejection repeatedly cooperates with the portable screen seat, the portable screen seat is by the support that is fixed on the frame, can form around sieve seat board and sieve seat board back-moving spring that fulcrum rotates, the sieve seat board has one section to form the arcuation edge that ejection repeatedly cooperates with a sieve supporting plate; A sieve seat supporting plate comprises support and elasticity activity supporting plate, by the torque spring on the connecting axle that is contained between support and the supporting plate to supporting plate with spacing.

The utility model utilizes hot-air seasoning tealeaves, its course of work is as follows: from top to bottom place to hold in the roasting chamber and remain the tea sieve of tea curing leaf, separate by screen frame (unit) between the tea sieve, undermost tea screen frame (unit) drops on the sliding seat, 8～12 tea sieves generally can be placed in the roasting teahouse, hot blast blasts the roasting teahouse by air inlet, tealeaves in the tea sieve of roasting teahouse is dried gradually, moisture content distributes from the nozzle in roasting teahouse, every through a setting-up time, to bake the nethermost whole sieve tealeaves of having dried in teahouse and take out, the superiors in the roasting teahouse put into the tea sieve that holds the tealeaves that remains to be dried by the fire again then, carry out the drying tea leaves operation by this program that picks and places the tea sieve.The method of getting roasting teahouse orlop tea sieve is, start motor, the holder sieve plate is risen, when the holder sieve plate is raised to the holder sieve position of portable screen seat, the sieve seat supporting plate of holder sieve plate periphery pushes away holder sieve position with the portable screen seat, the undermost tea sieve in roasting teahouse is fallen on the holder sieve plate, the tea sieve that the holder sieve plate is carried in the roasting teahouse by Motorized lift device descends then, the holder sieve plate is in the decline process, when contained orlop tea sieve drops to the holder sieve position of leaving the portable screen seat, the portable screen seat automatically resets under the spring force effect, hold the inferior lower floor tea sieve of decline, at this moment motor is turned off power supply, and the holder sieve plate just only is being with orlop tea sieve to drop to screening mouth, from the tealeaves taking-up of here the tea sieve being ined succession and wherein having dried.

The utility model is to tealeaves cycle operation continuously, tealeaves does not produce from going into to going out in drying course and stirs, thereby the original desirable bar shaped of maintenance tealeaves, avoid the generation of fannings, because tealeaves all shifts out with sieve, there is not tealeaves to remain in the roasting teahouse, produce the smell of burning, make tea color U.S., matter is more excellent; This tea drier is simple in structure, flexible and convenient operation, and high efficiency has than the more superior combination property of traditional tea oven dry machinery.
