Description

Green tea processing device

Technical Field

The invention relates to the technical field of tea processing, and particularly relates to a green tea processing device.

Background

Fresh tea leaves are processed into final finished products through a plurality of procedures such as sunning, screening, fixation, rolling, fermentation, drying and the like, and each procedure has very important influence on the quality of the tea leaves. Because the green tea is not fermented in processing, the influence of green removing on the color of the green tea is very important. The traditional green tea enzyme deactivating method generally adopts manual operation, namely, tea leaves to be processed are put into a frying pan and then manually stir-fried to complete enzyme deactivating; according to the method, the stir-frying is carried out by hands, on one hand, bacteria are easy to breed, on the other hand, the stir-frying frequency is different, so that the stir-frying is easy to be uneven, and in addition, the labor intensity of manual stir-frying is higher, so that the method is not suitable for large-scale production and processing.

In order to solve the problems, a drum-type enzyme deactivating machine is mostly adopted in the prior art, tea leaves to be processed are mainly put into a drum, the drum is utilized to rotate to drive blades in the drum to rotate, the drum is heated in the process, so that moisture in the tea leaves is rapidly evaporated, and enzyme deactivating is completed.

Although the roller type green removing machine solves the defect of manual stir-frying, the roller type green removing machine still has some points to be improved: the cylinder is the mode down that completes, because tealeaves rotates along with the cylinder, consequently tealeaves mainly is with the contact of cylinder wall, and the tealeaves after being heated takes place to curl easily, leads to whole bud leaf dehydration unbalance easily under this condition, and the tealeaves edge dehydration is fast and more promptly, and the central dehydration of tealeaves is slow and less to cause tealeaves to complete inhomogeneous problem.

The invention aims to provide a green tea processing device to solve the problem of uneven fixation of tea leaves in the prior art.

In order to achieve the purpose, the technical scheme adopted by the invention is as follows:

the green tea processing device comprises a rack, wherein a frying pan, an air supply box and an air guide chamber are arranged on the rack, a cavity communicated with the air supply box and the air guide chamber is formed in the frying pan, an air outlet is formed in the air guide chamber, a turbine is rotationally connected in the air guide chamber, and the turbine is coaxially connected with a sector gear; the tea leaf extruding and stirring machine is characterized in that a sliding plate and a sliding block are connected to the machine frame in a sliding mode, a first spring is connected between the sliding plate and the machine frame, a rotating shaft penetrating through the sliding plate is connected to the sliding plate in a rotating mode, one end of the rotating shaft is connected to the sliding block in a rotating mode, a first torsion spring is connected between the rotating shaft and the sliding block, a flat plate used for extruding and stirring tea leaves is fixedly connected to the other end of the rotating shaft, a first gear capable of being meshed with a sector gear is fixedly sleeved on the rotating shaft, a second gear capable of being meshed with the sector gear is connected to the machine frame in a rotating.

The principle of the invention is as follows: the tea leaves to be processed are put into the frying pan, the frying pan is heated by supplying hot air with appropriate temperature into the cavity of the frying pan through the air supply box, so that the air supply box can be adjusted in advance according to the type of the tea leaves to set the temperature of the hot air so as to realize better fixation. Because the air guide chamber is communicated with the cavity, hot air which is heated in the cavity enters the air guide chamber and is discharged from an air outlet on the air guide chamber; in the process, continuous air flow is formed in the air guide chamber, the air flow is used as a driving force to drive the turbine to rotate, and the turbine intermittently drives the first gear and the second gear to rotate through the sector gear; when the second gear rotates, the cam is driven to rotate, the sliding plate can reciprocate under the action of the first spring and the cam, the sliding rod can drive the rotating shaft to reciprocate, and the rotating shaft is connected to the sliding block in a rotating mode at the moment, and the sliding block is connected to the rack in a sliding mode, so that the sliding block can support the sliding of the rotating shaft. In the process, the rotating shaft drives the flat plate to move back and forth, when the flat plate is close to the frying pan, the tea is pressed in the frying pan, so that the tea is stewed and pressed, the tea is enzyme-deactivated and thoroughly deactivated, and the red stalks are prevented from being generated; when the flat plate is reset, the sector gear rotates to be meshed with the first gear, the flat plate is driven to rotate through the rotating shaft at the moment, tea leaves are stirred, the braised and pressed tea leaves are shaken and dispersed, evaporation of water is accelerated, and meanwhile the first torsion spring deforms; when the sector gear is separated from the first gear, the first torsion spring restores deformation and drives the flat plate to reversely reset through the rotating shaft, and the flat plate is used for stirring the tea again in the process so as to accelerate enzyme deactivation.

Further, an inner cavity is arranged in the flat plate, a through hole is formed in one side, facing the frying pan, of the flat plate, a guide pipe is communicated between the cavity and the air supply box, and a valve is installed on the guide pipe. When the flat plate extrudes the tea leaves, the valve is opened to communicate the inner cavity and the air supply box, at the moment, hot air enters the inner cavity, is discharged from the through hole and flows into the tea leaves to directly heat the tea leaves, and the stewing and pressing effects are promoted. When the flat plate is far away from the tea or is stirred, the valve is closed, hot air is not discharged from the through hole any more, and the tea can be prevented from being blown out of the frying pan. The air quantity of the through hole can be controlled by adjusting the valve, so that the effect of adjusting the stewing pressure is achieved.

Furthermore, a valve rod is arranged on the valve, a second spring is connected between the valve rod and the guide pipe, a wedge groove is formed in the valve rod, and a wedge rod used for abutting against the wedge groove is fixedly connected to the sliding plate. When the sliding rod drives the flat plate to be close to the tea leaves, the wedge rod is driven to move, when the flat plate is in contact with the tea leaves to extrude the tea leaves, the wedge rod is just inserted into the wedge groove, the valve rod is pushed through the wedge groove, the valve is opened, and hot air in the air supply box enters the inner cavity. Through setting up the wedge rod, utilize the reciprocating motion realization of slide to the automatic start-stop of valve, need not manual operation, make this device more automatic.

Further, the edge of the flat plate is arc-shaped. When the flat plate rotates, the arc-shaped structure and the inner wall of the frying pan form point contact, so that the abrasion is reduced, meanwhile, the tea leaves can be prevented from being broken by rubbing, and the quality of the tea leaves is ensured.

Further, the frying pan comprises an inner wall and an outer wall, wherein the inner wall is provided with a heat conduction layer, and the outer wall is provided with a heat insulation layer. Set up the heat-conducting layer, can transmit hot-blast temperature for tealeaves fast for the green-removing of tealeaves, and set up the insulating layer, can reduce thermal scattering and disappearing, play heat retaining effect.
