Description

A cylinder drying device for quickly drying tea leaves

technical field

The invention relates to the technical field of tea drying, in particular to a cylinder drying device for quickly drying tea.

Background technique

With the continuous improvement of people's living standards, drinking tea and tasting tea have become a symbol of quality of life. However, tea leaves cannot be eaten directly after they are picked from the tea tree. The process is very troublesome, so the tea dryer is one of the indispensable equipment in the tea processing process. The existing tea dryers have some defects in the heating process, for example, the space inside the box dryer is limited. The production capacity is low, and the time required for drying is long. According to this problem, we have designed a cylindrical drying device with reverse flow of hot gas and rotation function.

Contents of the invention

The present invention aims at the deficiencies of the above-mentioned prior art, and provides a cylinder drying device with simple structure, large production capacity, and reverse flow of hot air and tea leaves.

The technical solution adopted by the present invention to solve the above technical problems is: a cylindrical drying device for quickly drying tea leaves, which includes a cylinder with an inclined design, an annular rack is arranged on the outer wall of the cylinder, and the annular rack and the transmission gear mesh with each other , the transmission gear is driven by the drive motor installed on the workbench, the upper end of the inclined cylinder is connected to the feeding chamber, the lower end of the inclined cylinder is connected to the discharge chamber, and the cylinder is provided with a mesh tube , and there is an air flow layer between the outer wall of the mesh cylinder and the inner wall of the cylinder, and the inner wall of the mesh cylinder is provided with uniform lifting plates; the feeding chamber is connected to the heater, and the junction of the heater and the feeding chamber is provided There is a first mesh sieve plate, and an air outlet is provided on the heater; the discharge chamber communicates with the hot gas chamber, and a layer of second mesh sieve plate is arranged at the junction of the hot gas chamber and the discharge chamber, and the hot gas chamber There is an air return port and an air inlet on the chamber. The drive motor drives the transmission gear to rotate, and the transmission gear drives the rotation of the cylinder through the ring rack. The air inlet at the bottom enters, and the gas and solid contact in countercurrent in the cylinder. With the rotation of the cylinder, the tea leaves will flow to the outlet at the inclined lower part of the cylinder due to the action of gravity.

The beneficial effects of the present invention are:

1. There is a net cylinder inside the cylinder, and there is an airflow layer between the outer wall of the net cylinder and the inner wall of the cylinder, part of the hot air passes through the airflow layer, and then flows into the net cylinder through the mesh holes on the net cylinder, so that the tea leaves are not easy to stick on the net drum.

2. On the inner wall of the net cylinder, there are evenly divided lifting boards, which can shake the tea leaves and then sprinkle them, so as to increase the drying surface area, improve the drying efficiency, and at the same time promote the tea leaves to move forward.

3. The feed chamber is connected to the heater. There is a layer of first mesh sieve plate at the junction of the heater and the feed chamber. There is an air outlet on the heater. The air outlet and the return air are connected by an insulating rubber tube. After countercurrent and wet tea leaves, it will become humid air. After the heating air is dried and heated, the hot air is transported from the air outlet to the return air port. The heat loss is ensured through the insulating rubber tube, and the hot air is recycled to improve thermal efficiency.

detailed description

In order to deepen the understanding of the present invention, the present invention will be further described below in conjunction with the examples and accompanying drawings. The examples are only used to explain the present invention and do not constitute a limitation to the protection scope of the present invention.

As shown in Figures 1 to 2, a cylindrical drying device for quickly drying tea leaves includes a cylinder 1 with an inclined design, and an annular rack 2 is arranged on the outer wall of the cylinder 1, and the annular rack 2 and the transmission gear 3 are meshed with each other. The transmission gear 3 is driven by the driving motor 4 installed on the workbench. The upper end of the inclined cylinder 1 is connected to the feeding chamber 6, and the lower end of the inclined cylinder 1 is connected to the discharge chamber 7. There is a net cylinder 17, and an airflow layer 18 is left between the outer wall of the net cylinder 17 and the inner wall of the cylinder 1, and the inner wall of the net cylinder 1 is provided with uniform lifting plates 19; the feeding chamber 6 communicates with the heater 12, The junction of the heater 12 and the feed chamber 6 is provided with a first mesh sieve plate 10, and the heater 12 is provided with an air outlet 8; the discharge chamber 7 communicates with the hot gas chamber 13, and the hot gas chamber 13 A layer of second mesh sieve plate 11 is provided at the junction with the discharge chamber 7 , and an air return port 15 and an air inlet port 16 are provided on the hot gas chamber 13 .

The feed chamber 6 is provided with a feed port 10 , and the discharge chamber 7 is provided with a discharge port 9 .

Both the top and bottom of the cylinder 1 are supported by the roller bracket 5 installed on the workbench.

The air outlet port 14 and the air return port 15 are connected by an insulating rubber tube.

Before using the drying device, the air intake speed of the hot air is controlled at 0.1-0.5m/s, and the relatively slow air intake speed ensures that the tea leaves can be dried without being blown back. The inclination angle of the cylinder 1 is controlled at 8°-12° °, to ensure a slow forward movement of the tea leaves during the drying process.

After the present invention is installed, pour tealeaves into through feeding port 8, when cylinder 1 rotates one circle, the lifting board 19 on the inner wall of mesh tube 17 in cylinder 1 picks up and sprinkles tealeaves once, and Both the first mesh sieve plate 10 and the second mesh sieve plate 11 have a blocking effect on the tea leaves in the cylinder 1, so that air can flow through, and the heating and tea leaves are in reverse contact, greatly improving the drying effect.

Although the embodiments of the present invention have been shown and described, those skilled in the art can understand that various changes, modifications and substitutions can be made to these embodiments without departing from the principle and spirit of the present invention. and modifications, the scope of the invention is defined by the appended claims and their equivalents.
