Description

Technical Field

[0001] The utility model belongs to the technical field of tea processing and relates to a tea fixation machine. Background Art

[0002] Tea fixation is an important link in traditional manual tea-making technology, and this process has a decisive impact on the aroma, taste and color of tea. The main purpose of fixation is to destroy the enzyme activity in tea through high temperature, prevent the fermentation process of tea, and maintain the green color and fresh taste of tea. In the tea-making process, different fixation methods can be adopted, and the common ones are stir-frying fixation, steaming fixation, fixation by a fixation machine, etc. In the existing fixation machines, it is inevitable that there will be debris during the fixation process, and these debris will be mixed into the tea during feeding, thus affecting the quality of the tea and requiring subsequent filtration treatment. Therefore, in order to separate tea and debris while feeding tea and improve production efficiency, it is very necessary to design a tea fixation machine. Summary of the Invention

[0003] The purpose of the utility model is to provide a tea fixation machine aiming at the above problems existing in the current technology.

[0004] The purpose of the utility model can be realized by the following technical solutions: A tea fixation machine includes a frame. It is characterized in that an outer cylinder is inclinedly arranged on the frame, and an inner cylinder is rotatably connected in the outer cylinder through a connecting shaft. The end of the connecting shaft is connected with a driving mechanism. The top of the inner cylinder is provided with a feed inlet, and the bottom of the inner cylinder is provided with a discharge outlet. A cylinder cover is installed at the discharge outlet. A heating component is installed on the connecting shaft inside the inner cylinder. An opening one is arranged at the position corresponding to the feed inlet at the top of the outer cylinder. An exhaust device is installed at the middle position at the top of the outer cylinder. An opening two is arranged at the position corresponding to the discharge outlet at the bottom of the outer cylinder, and the opening two communicates to the outside of the frame. A protrusion is arranged on the frame outside the opening two, and a blowing fan is arranged below the protrusion. The area below the protrusion is a collection area, and the collection area includes a tea collection area and a tea debris collection area. The tea collection area is located in front of the tea debris collection area and close to the protrusion. A guide plate is installed in the tea collection area, and a conveyor belt for transporting tea is arranged at the end of the guide plate.

[0005] The working principle of the utility model is as follows: The tea to be fixed is added into the inner cylinder through the feed inlet from the opening one. The driving mechanism is started to drive the inner cylinder to rotate, and at the same time, the inside of the inner cylinder is heated through the heating component to fix the tea by heating. During this period, the water vapor evaporated by the tea flows out through the feed inlet, and the exhaust device is used to assist in discharging the water vapor out of the outer cylinder. When the tea fixation is completed, the cylinder cover at the discharge outlet is opened, and the tea is led out along the opening two under the action of gravity. Due to the different weights of the tea and the tea debris, under the action of the blowing fan, the tea and the tea debris respectively fall into the tea collection area and the tea debris collection area. The tea in the tea collection area is guided by the guide plate to the conveyor belt and output for subsequent processing.

[0006] The driving mechanism includes a driving motor, a main pulley is installed on the output shaft of the driving motor, the main pulley is connected to a driven pulley through a transmission belt, and the driven pulley is installed at the end of a connecting shaft outside the inner cylinder.

[0007] With the above structure, the rotation of the inner cylinder is realized through the pulley structure controlled by the driving motor.

[0008] A material guiding member is arranged inside the first opening.

[0009] With the above structure, it is convenient to introduce the tea leaves.

[0010] The cylinder cover is installed at the discharge port through a threaded structure.

[0011] With the above structure, it is ensured that the tea leaves will not leak out during the tea fixation process.

[0012] A heat conducting layer is wrapped outside the heating component.

[0013] With the above structure, it is avoided that the tea leaves directly contact the heating component, thus affecting the quality of the tea leaves.

[0014] An opening three is also provided at the position of the blowing fan on the frame.

[0015] With the above structure, the opening three is used as the air inlet of the blowing fan.

[0016] Compared with the prior art, the tea fixation machine has the following advantages: by setting a streamlined structure, while ensuring the tea fixation effect, it can separate the tea leaves and debris during the tea leaf feeding process, improving the production efficiency.
