Abstract
Description
Technical Field
[0001] The utility model relates to the field of tea processing equipment, in particular to a tea withering and cooling machine. Background Art
[0002] Withering is a key step in the tea processing process. Its main purpose is to terminate the enzyme activity in the fresh leaves through high temperature treatment to prevent oxidation, while reducing moisture, forming a specific aroma, and improving the quality of the tea. It not only ensures the flavor and color of the tea, but also provides the possibility for the long-term preservation of the tea.
[0003] After withering, the tea leaves need to be cooled in time, otherwise it is easy to become stuffy and heat-reverse, affecting the quality of the tea leaves. The existing cooling after withering mainly relies on manually spreading the tea leaves and letting them cool, which has high labor intensity and low processing efficiency. The purpose of the utility model is to propose a device that can solve the above technical problems. Utility Model Content

[0006] To optimize the above technical solution, further measures are taken: blades are arranged on the side of the column block, and the tea leaves can drive the blades to flip the column block during the sliding process of the conveying trough, which helps to turn the tea leaves over.
[0007] As a further improvement to the above technical solution: the bottom ends of the conveying trough and the collecting trough extend to the outside of the convergence cavity to prevent tea debris and powder from escaping to the outside.
[0008] As a further improvement of the technical solution: the top of the conveying trough extends to the outside of the convergence cavity. Such an extension design is to facilitate the delivery of tea leaves into the conveying trough.
[0009] As an improvement on the aforementioned technical solution: the top, middle and bottom of the convergence cavity are connected to the conveying trough. The purpose of setting the convergence cavity is to converge the airflow to improve the cooling effect of the airflow on the tea leaves, and the three-point connection structure ensures the connection strength while not causing strong interference to the airflow.
[0010] From the above description of the structure of the utility model, it can be seen that compared with the prior art, the utility model has the following advantages:
[0011] The utility model provides a tea withering and cooling machine, which uses a unique annular structure to transport tea leaves and cooperates with a fan to achieve tea leaf cooling. During the process, the air carrying heat will be converged and leave from the top of the convergence chamber to ensure the cooling effect of the air on the tea leaves. In addition, during the transportation process, the debris and dust in the tea leaves will be separated from the tea leaves and collected in a collecting trough, which helps to improve the quality of the tea leaves.

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0017] Example
[0018] See also Figure 1-2 The utility model provides a tea withering and cooling machine, comprising a conveying trough 1, a collecting trough 2, a column block 3, a focusing chamber 4 and a fan 5. The conveying trough 1 is spirally wound from bottom to top, tea leaves are input from the top of the conveying trough 1 and a filter screen 101 is arranged on the bottom of the conveying trough 1.
[0019] The collecting groove 2 is located at the bottom of the conveying groove 1 and is spirally shaped. The collecting groove 2 is located below the filter 101 and surrounds both sides of the bottom of the conveying groove 1. The bottom ends of the conveying groove 1 and the collecting groove 2 extend to the outside of the convergence cavity 4, and the top end of the conveying groove 1 extends to the outside of the convergence cavity 4.
[0020] The column block 3 is installed at the bottom of the conveying trough 1 and can rotate to form a rotating pair with the conveying trough 1. The side of the column block 3 is provided with a blade 301.
[0021] The two ends of the convergence chamber 4 are open. The convergence chamber 4 is arranged outside the conveying trough 1 and the collecting trough 2. The top, middle and bottom of the convergence chamber 4 are connected to the conveying trough 1. The purpose of setting the convergence chamber 4 is to converge the airflow so that the tea leaves can be fully cooled.
[0022] The fan 5 is located at the bottom of the convergence cavity 4 , and the airflow generated by the fan 5 is directed toward the middle of the conveying trough 1 and the collecting trough 2 .
[0023] Working principle: tea leaves are input from the top of the collecting trough 2, and under the action of gravity, the tea leaves can be input along the spirally coiled conveying trough 1. When the tea leaves come into contact with the column block 3, the tea leaves can drive the blades 301 on the column block 3 to rotate the column block 3, so that the tea leaves can be turned over during the sliding process along the collecting trough 2, so that the tea leaves can be evenly cooled. In addition, during the sliding process of the tea leaves in the collecting trough 2, tea debris and dust can be separated from the tea leaves through the filter screen 101 and fall into the collecting trough 2 to be collected uniformly.
[0024] During the cooling process of tea leaves, the airflow generated by the fan 5 passes through the center of the spiral structure formed by the collecting trough 2 from bottom to top, and can fully cool the tea leaves in the collecting trough 2. After the airflow takes away the heat of the tea leaves, it will move upward due to the volume expansion and density decrease due to the heat. These hot airflows will eventually be converged by the convergence cavity 4 and will be concentrated and leave from the top of the convergence cavity 4, ensuring the cooling efficiency of the airflow on the tea leaves.
[0025] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
