[0002] The instant tea powder high-speed airflow pulverizer is a high-efficiency pulverizing equipment used in the production and processing of instant tea powder. The pulverizer uses high-speed airflow as the pulverizing medium, and accelerates the tea powder particles to a certain speed through high-pressure air. Then, under the action of the airflow, the tea powder collides and rubs against each other in the pulverizing chamber to achieve the purpose of pulverization. The pulverizer has the advantages of fine pulverizing particle size, energy saving and environmental protection, and can effectively improve the quality and taste of instant tea powder;

[0003] The existing high-speed air flow pulverizer for instant tea powder does not crush thoroughly enough in actual application, and some tea powder particles are large, affecting the uniformity and quality of the final product. Secondly, when processing tea powder of different particle size levels, the pulverizer is difficult to achieve effective screening, resulting in insufficient fineness of the particle size distribution and failure to meet the market demand for high-quality instant tea powder. These problems limit the production efficiency and product quality of instant tea powder to a certain extent. Utility Model Content

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] In this embodiment, a plurality of transverse plates 14 are fixedly connected to the top of the rotating cage 11 , and a fixed plate 15 is fixedly connected to the top of the filter screen 13 .

[0023] The horizontal plate 14 can rotate along with the rotating cage 11 and hit the tea powder while rotating, thereby increasing the crushing rate and improving the crushing effect.

[0024] In this embodiment, support rods are symmetrically provided on both sides of the fixing plate 15 , and a circular hole is opened on the top of the fixing plate 15 and penetrates to the bottom.

[0025] The fixing plate 15 is connected to the filter screen 13 through the stem-like protrusions at both ends, and is connected to the impeller 10 through the circular holes, so as to constrain the impeller 10 and reduce the shaking of the impeller 10 .

[0026] In this embodiment, circular holes are opened on the top, bottom and one side of the pulverizer housing 1, and the outer shape of the pulverizer housing 1 is funnel-shaped.

[0027] The crusher housing 1 is used for feeding and discharging materials through the circular hole on the top, and the residual materials can be cleaned by opening the bottom valve 3 .

[0028] In this embodiment, a plurality of plate-shaped protrusions are provided on the outer side of the impeller 10, and a shaft-shaped protrusion is provided in the middle of the impeller 10, and the plurality of plate-shaped protrusions are connected through the shaft-shaped protrusion.

[0029] The plate-shaped protrusions of the impeller 10 can project and fan the passing tea powder while rotating, so that smaller tea powder can pass through the filter screen 13 for secondary screening.

[0030] In this embodiment, a through hole is opened at the bottom of the cover shell 12 , and the diameter of the through hole matches the outer diameter of the filter screen 13 , and a plurality of meshes are opened on the outer side of the filter screen 13 .

[0031] The inner side of the cover 12 can accommodate the filter 13 and intercept the tea powder passing through the filter 13 .

[0032] In this embodiment, a plurality of sheet-like protrusions are disposed in the middle of the rotating cage 11 , and the plurality of sheet-like protrusions are radially and evenly arranged on the outer side of the rotating cage 11 , and a columnar protrusion is disposed on the inner side of the rotating cage 11 .

[0033] The rotating cage 11 is connected to the impeller 10 through a columnar protrusion and rotates together with the impeller 10. The rotating cage 11 can accommodate the crushed tea powder to pass through and screen the tea powder.

[0034] It should be noted that the utility model is a high-speed airflow pulverizer for instant tea powder. When in use, the crushing effect can be increased by the transverse plate 14, and the tea powder can be screened twice. In order to improve the product quality, the specific implementation method is to start the motor 9, and the motor 9 drives the impeller 10 to rotate while the motor 9 rotates. The impeller 10 drives the rotating cage 11 to rotate together. After the rotating cage 11 rotates, it will drive the transverse plate 14 connected thereto to rotate synchronously, and then the air pipe 8 is connected to the high-pressure air source, so that the air passes through the air pipe 8 and blows the high-speed airflow into the interior of the pulverizer housing 1;

[0035] Then the raw materials are put into the inside of the crusher housing 1 through the two feeding ports 5. After entering the crusher housing 1, the raw materials will fall under the action of gravity, and in the process of falling, they will pass through the high-speed rotating cross plate 14, and the cross plate 14 will hit the raw materials to break the raw materials. When hitting the raw materials, the cross plate 14 will eject a part of the raw materials to the inner wall of the crusher housing 1 to break the raw materials again. The broken raw materials fall to the position of the air pipe 8, and are carried by the high-speed airflow blown out of the air pipe 8 to move and cause the raw materials to collide with each other, and are carried by the airflow to collide with the inner wall of the crusher housing 1, so that the raw materials are further broken. Through multiple collisions, the crushing effect of the raw materials is increased.

[0036] After being crushed, the smaller particles move upwards due to their lighter weight under the entrainment of the airflow. The tea powder with small enough particles will pass through the gap of the rotating cage 11, and the tea powder with larger particles will be blocked by the rotating cage 11 and continue to be crushed inside the pulverizer housing 1 until it reaches a size that can pass through the rotating cage 11. After passing through the rotating cage 11, the tea powder moves to the range of the impeller 10, and in the process of passing through the impeller 10, it is impacted by the impeller 10 and thrown toward the filter 13;

[0037] Tea powder smaller than the mesh size of the filter 13 will enter the interlayer of the cover 12 and the filter 13, and will be discharged through the discharge port 1 6 under the blowing of the airflow. Tea powder that has not passed through the filter 13 will move out of the range of the impeller 10 under the blowing of the airflow, and will be discharged through the discharge port 2 7. By performing secondary screening on the tea powder, tea powder of different particle sizes can be classified, which helps to improve the quality of the tea powder and classify different qualities.

[0038] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
