Description

Technical Field

[0001] This utility model relates to the field of tea production, specifically a cooling machine for tea production. Background Technology

[0002] In the tea production process, the cooling process is one of the key steps affecting the quality of tea. Tea leaves that have just undergone heat processing such as fixation and rolling are at a high temperature. If they are not cooled in time and effectively, the tea leaves will continue to ferment, causing the color of the tea to darken and the aroma to be lost, which will seriously affect the quality and taste of the tea. Currently, the cooling methods used in tea production have many shortcomings. Although natural cooling is simple and inexpensive, its cooling efficiency is extremely low, it is greatly affected by external factors such as ambient temperature and humidity, and its cooling effect is unstable, making it difficult to meet the needs of large-scale, continuous production. In mechanical cooling methods, some equipment uses either air cooling or water cooling alone. Air cooling equipment typically cools the tea leaves by blowing air onto them with a fan. However, because the tea leaves are piled up, the airflow cannot penetrate evenly, resulting in uneven cooling and some tea leaves not being cooled sufficiently. Water cooling equipment, on the other hand, cools the tea leaves by contacting them with cold water. Although this method is fast, it requires drying the tea leaves, which increases the production process. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a cooling machine for tea production to solve the shortcomings of the prior art.

[0004] The purpose of this utility model is achieved through the following technical solution: a cooling machine for tea production, including a frame and a cooling cylinder installed on the frame. The cooling cylinder is installed horizontally, and a cooling hose is wound around the cooling cylinder. The cooling hose is spirally wound along the axial direction of the cooling cylinder, and a gap is formed between adjacent threaded sections. The two ends of the cooling hose are a cold water inlet and an outlet, respectively. A number of sieve holes are densely opened on the side wall of the cooling cylinder. A suction plate is provided above the cooling cylinder, and a negative pressure cavity is formed inside the suction plate. A number of suction holes are opened at the bottom of the suction plate, and the suction holes are connected to the negative pressure cavity.

[0005] Furthermore, one end of the cooling cylinder is open along the axial direction, and a stirring mechanism is provided inside the cooling cylinder. The stirring mechanism includes a stirring shaft and a motor. The stirring shaft is rotatably installed at the other end of the cooling cylinder along the axial direction. Several arc-shaped blades are fixed on the stirring shaft. The motor is installed on the cooling cylinder, and the output shaft of the motor is connected to the stirring shaft.

[0006] Furthermore, the suction plate is connected to a negative pressure pump via a negative pressure pipe.

[0007] Furthermore, it also includes a base, the frame is hinged to the base, a cylinder is provided between the base and the frame, the cylinder body is hinged to the base, and the telescopic shaft of the cylinder is hinged to the frame.

[0008] Furthermore, a U-shaped seat is fixed on the base, and a horizontal shaft is fixed inside the U-shaped seat. The axis of the horizontal shaft is perpendicular to the axis of the cooling cylinder. The frame is movably sleeved on the horizontal shaft, and the hinge axis of the cylinder is parallel to the horizontal shaft.

[0009] Furthermore, a fan is provided at the open end of the cooling cylinder, and the fan has the freedom to move along the axial direction of the cooling cylinder.

[0010] Furthermore, a push cylinder is horizontally mounted on the base, and the telescopic shaft of the push cylinder is connected to a sliding plate, with the fan mounted on the sliding plate.

[0011] The beneficial effects of this utility model are: 1. The spirally wound cooling hose on the outside of the cooling cylinder forms a full heat exchange contact with the cooling cylinder. The continuous flow of cold water in the hose can quickly remove the heat from the tea leaves. At the same time, the suction plate above the cooling cylinder forms a high-efficiency suction through the negative pressure chamber and suction holes. Combined with the sieve holes on the side wall of the cooling cylinder, it realizes the rapid replacement of hot and cold air. The synergistic effect of water cooling and air cooling greatly improves the cooling efficiency and is not affected by external environmental factors. The cooling effect is stable and reliable.

[0012] 2. The stirring mechanism inside the cooling cylinder is driven by a motor to rotate the stirring shaft and arc-shaped blades, which can continuously turn the tea leaves, so that all the tea leaves can evenly contact the inner wall of the cooling cylinder and the airflow inside the cylinder. This avoids the problem of insufficient cooling in some areas due to the accumulation of tea leaves, and ensures that each batch of tea leaves can achieve a consistent cooling effect, effectively preventing local continuous fermentation from affecting the quality.

[0013] 3. The cooling hose adopts an indirect heat exchange method, which does not come into direct contact with the tea leaves, thus avoiding the risk of the cooling medium contaminating the tea leaves in traditional water-cooled equipment. Attached Figure Description

Detailed Implementation

[0015] Example 1 like Figures 1 to 3 As shown, a tea processing cooling machine includes a frame 1 and a cooling cylinder 2 mounted on the frame 1. The cooling cylinder 2 is horizontally mounted, and a cooling hose 3 is wound around it. The cooling hose 3 is spirally wound along the axial direction of the cooling cylinder 2, with gaps between adjacent spiral sections. The two ends of the cooling hose 3 are a cold water inlet and an outlet, respectively. Several sieve holes are densely arranged on the side wall of the cooling cylinder 2. A suction plate 4 is installed above the cooling cylinder 2, forming a negative pressure cavity 5. Several suction holes 6 are opened at the bottom of the suction plate 4, connecting to the negative pressure cavity 5. One axial end of the cooling cylinder 2 is open, and tea leaves are fed into the cooling cylinder 2 through this opening. The spirally wound cooling hose 3 forms a sufficient heat exchange contact with the cooling cylinder 2. External cold water flows in from the cold water inlet and out from the outlet, allowing the cold water to flow continuously within the cooling hose 3 and quickly remove heat from the tea leaves. Since the cooling hose 3 does not completely cover the cooling cylinder 2, the hot air inside the cooling cylinder 2 can be discharged through the sieve holes. The suction plate 4 forms a highly efficient suction through the negative pressure chamber 5 and the suction holes 6, achieving rapid replacement of hot and cold air. The synergistic effect of water cooling and air cooling greatly improves the cooling efficiency and is not affected by external environmental factors, ensuring a stable and reliable cooling effect. Furthermore, the cooling hose 3 adopts an indirect heat exchange method and does not come into direct contact with the tea leaves, avoiding the risk of the cooling medium contaminating the tea leaves in traditional water-cooled equipment.

[0016] Furthermore, the suction plate 4 is connected to a negative pressure pump through a negative pressure pipe, and the negative pressure pump causes the suction hole 6 to generate suction to quickly remove the hot air.

[0017] Example 2 Based on Example 1, such as Figure 1 and Figure 2 As shown, a stirring mechanism is installed inside the cooling cylinder 2. The stirring mechanism includes a stirring shaft 7 and a motor 8. The stirring shaft 7 is rotatably installed at the other end of the cooling cylinder 2 along its axis. Several arc-shaped blades 9 are fixed on the stirring shaft 7. The motor 8 is installed on the cooling cylinder 2. The output shaft of the motor 8 is connected to the stirring shaft 7. The motor 8 drives the stirring shaft 7 to rotate, and the stirring shaft 7 drives the arc-shaped blades 9 to rotate, which can continuously agitate the tea leaves, so that all the tea leaves can evenly contact the inner wall of the cooling cylinder and the airflow inside the cylinder, avoiding the problem of insufficient cooling in some areas due to the accumulation of tea leaves.

[0018] Example 3 Based on Embodiment 2, it also includes a base 10, with the frame 1 hinged to the base 10. A cylinder 11 is provided between the base 10 and the frame 1, with the cylinder body of the cylinder 11 hinged to the base 10 and the telescopic shaft of the cylinder 11 hinged to the frame 1. A U-shaped seat 12 is fixed on the base 10, and a horizontal shaft 13 is fixed inside the U-shaped seat 12. The axis of the horizontal shaft 13 is perpendicular to the axis of the cooling cylinder 2. The frame 1 is movably sleeved on the horizontal shaft 13, and the hinge axis of the cylinder 11 is parallel to the horizontal shaft 13. The tilt angle of the cooling cylinder 2 is adjusted by the telescopic movement of the cylinder 11. After cooling is completed, the open end of the cooling cylinder 2 is deflected downwards, and the tea leaves in the cooling cylinder 2 are discharged in conjunction with the operation of the stirring mechanism.

[0019] Example 4 Based on Example 3, such as Figure 1 As shown, a fan 14 is provided at the open end of the cooling cylinder 2. The fan 14 has the freedom to move along the axial direction of the cooling cylinder 2. A push cylinder 15 is horizontally installed on the base 10. The telescopic shaft of the push cylinder 15 is connected to a slide plate 16. The fan 14 is installed on the slide plate 16. The fan 14 blows air into the cooling cylinder 2 to aerate the tea leaves inside, preventing the tea leaves from accumulating. In conjunction with the stirring mechanism, it can better turn the tea leaves. The push cylinder 15 drives the slide plate 16 to move, which is used to adjust the position of the fan 14 so that the fan 14 is away from the cooling cylinder 2 when feeding the tea leaves, so as not to affect the feeding of the tea leaves.
