A tea steam fermentation device

Abstract

This utility model discloses a tea steam fermentation device, relating to the field of tea fermentation technology. The tea steam fermentation device includes a fermentation cylinder, a stirring mechanism, and a steam mechanism. A cylinder cover is threaded onto the top of the fermentation cylinder. The steam mechanism is mounted on the fermentation cylinder and includes a spiral tube and jet nozzles. The spiral tube is fixedly installed on the inner wall of the fermentation cylinder, and at least two sets of jet nozzles are provided on the spiral tube. This tea steam fermentation device, through the spiral tube, sets multiple sets of steam inlet points and distributes them evenly in a spiral manner, ensuring that the steam can evenly contact all the tea leaves, guaranteeing the tea fermentation effect. This solves the problem of some existing devices only introducing steam from one point, which easily leads to uneven steam distribution within the chamber, with higher steam concentration and temperature near the inlet and lower temperature in areas farther away, resulting in inconsistent fermentation levels. This improves the practicality of the device.

Description

Technical Field

[0001] This utility model relates to the field of tea fermentation technology, and in particular to a tea steam fermentation device. Background Technology

[0002] Chinese patent document CN219069352U discloses a tea steam fermentation device, including a box body, a turning mechanism, and a steam mechanism. The box body houses a fermentation chamber. The turning mechanism, mounted on the box body, uses a combination of a motor, a rotating rod, and a turning block to rotate the turning block, thus better turning the tea leaves and ensuring each leaf is fully exposed to steam, accelerating the fermentation process. The steam mechanism, also mounted on the box body, generates steam to ferment the tea leaves. A heating zone is formed between the box body and the fermentation chamber. Steam discharged from the fermentation chamber passes through a permeable mesh into the heating zone, heating the interior of the fermentation chamber. This design saves energy and promotes better tea fermentation.

[0003] However, the above-mentioned device only introduces steam from one point. This single-point air intake method easily leads to uneven distribution of steam in the chamber. The steam concentration and temperature are high in the area near the air intake, while the temperature is low in the area far away, resulting in different degrees of fermentation. Therefore, we propose a tea steam fermentation device. Utility Model Content

[0004] The purpose of this invention is to provide a tea steam fermentation device that can solve the problem of uneven steam distribution in some existing devices.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tea steam fermentation device, comprising:

[0006] A fermentation cylinder with a screw-on lid at the top;

[0007] The stirring mechanism is located on the cylinder lid and is used to stir the tea leaves.

[0008] The steam mechanism, installed on the fermentation cylinder, includes a spiral tube and jet nozzles. The spiral tube is fixedly installed on the inner wall of the fermentation cylinder, and at least two sets of jet nozzles are opened on the spiral tube. Each set of jet nozzles communicates with the interior of the spiral tube. Through the spiral tube, multiple sets of steam inlet points are set and evenly distributed in a spiral manner, so that the steam can evenly contact all the tea leaves, ensuring the fermentation effect of the tea leaves. This solves the problem that some existing devices only introduce steam from one point. This single-point air intake method is prone to uneven steam distribution in the chamber. The steam concentration and temperature are high in the area near the air inlet, while the area far away is lower, resulting in uneven fermentation. This improves the practicality of the device.

[0009] Preferably, the steam mechanism further includes an air inlet pipe and a filling strip. The air inlet pipe is fixedly inserted through the fermentation cylinder. One end of the spiral tube is fixedly connected to the air inlet pipe, and the other end of the spiral tube is also connected to the interior of the air inlet pipe. A filling strip is fixedly installed on the inner wall of the fermentation cylinder. The filling strip can prevent tea leaves from getting stuck in the dead corner between the spiral tube and the inner wall of the fermentation cylinder due to the spiral tube alone, thus preventing tea residue and ensuring the effectiveness of the device. This is beneficial for the promotion and use of the device.

[0010] Preferably, the stirring mechanism includes a servo motor, a rotating rod, and a silicone plate. The servo motor is fixedly installed on the top of the cylinder cover, and the rotating rod is rotatably installed on the top inner side of the cylinder cover. The rotating shaft of the servo motor is connected to the rotating rod for transmission, and two sets of silicone plates are fixedly installed on the outer surface of the rotating rod.

[0011] Preferably, a feed pipe communicating with the interior of the fermentation cylinder is fixedly installed on the outer surface of the fermentation cylinder, and a first flip cover is hinged to the top of the feed pipe.

[0012] Preferably, an exhaust pipe communicating with the inside of the fermentation cylinder is fixedly installed on the top of the cylinder cover, and a second flip cover is hinged to the top of the exhaust pipe.

[0013] Preferably, a handle is fixedly installed on the outer surface of the cylinder cover.

[0014] Preferably, the bottom of the fermentation cylinder is integrally formed with a discharge port, and a discharge cover is threaded onto the discharge port.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) The tea steam fermentation device has multiple steam inlet points set up through a spiral tube and evenly distributed in a spiral manner, so that the steam can come into contact with all the tea leaves evenly, ensuring the tea fermentation effect. This solves the problem that some existing devices only introduce steam from one place. This single-point air intake method easily leads to uneven distribution of steam in the box. The steam concentration and temperature are high in the area near the air inlet, while the temperature is low in the area far away, resulting in uneven fermentation degree. This improves the practicality of the device.

[0017] (2) The tea steam fermentation device, through the filling strip, can avoid the dead corner between the spiral tube and the inner wall of the fermentation cylinder caused by only setting the spiral tube, thus preventing tea residue and ensuring the effectiveness of the device, which is conducive to the promotion and use of the device.

[0024] Please see Figure 1-3 This utility model provides a technical solution: a tea steam fermentation device, including a fermentation cylinder 1, a stirring mechanism 4 and a steam mechanism 3. The top of the fermentation cylinder 1 is threaded with a cylinder cover 2. The stirring mechanism 4 is set on the cylinder cover 2 and is used to stir the tea. The outer surface of the fermentation cylinder 1 is fixedly installed with a feed pipe 5 that communicates with its interior. The top of the feed pipe 5 is hinged with a first flap 6. The top of the cylinder cover 2 is fixedly installed with an exhaust pipe 7 that communicates with the interior of the fermentation cylinder 1. The top of the exhaust pipe 7 is hinged with a second flap 8. The outer surface of the cylinder cover 2 is fixedly installed with a handle 9. The bottom of the fermentation cylinder 1 is integrally formed with a discharge port, and a discharge cover 10 is threadedly installed at the discharge port.

[0025] The steam mechanism 3 is installed on the fermentation cylinder 1. The steam mechanism 3 includes a spiral tube 31 and jet holes 32. The spiral tube 31 is fixedly installed on the inner wall of the fermentation cylinder 1. At least two sets of jet holes 32 are opened on the spiral tube 31. Each set of jet holes 32 communicates with the interior of the spiral tube 31. Through the spiral tube 31, multiple sets of steam inlet points are set and evenly distributed in a spiral manner, so that the steam can evenly contact all the tea leaves, ensuring the fermentation effect of the tea leaves. This solves the problem that some existing devices only introduce steam from one place. This single-point air intake method is prone to uneven distribution of steam in the chamber. The steam concentration and temperature are high in the area near the air inlet, while the temperature is low in the area far away, resulting in uneven fermentation. This improves the practicality of the device.

[0026] The steam mechanism 3 also includes an air inlet pipe 33 and a filling strip 34. The air inlet pipe 33 is fixedly inserted through the fermentation cylinder 1. One end of the spiral tube 31 is fixedly connected to the air inlet pipe 33, and the other end of the spiral tube 31 is also connected to the inside of the air inlet pipe 33. The filling strip 34 is fixedly installed on the inner wall of the fermentation cylinder 1. The filling strip 34 can prevent tea leaves from getting stuck in the dead corner between the spiral tube 31 and the inner wall of the fermentation cylinder 1 due to the spiral tube 31 alone, thus preventing tea residue and ensuring the effectiveness of the device. This is beneficial for the promotion and use of the device.

[0027] The stirring mechanism 4 includes a servo motor 41, a rotating rod 42, and a silicone plate 43. The servo motor 41 is fixedly installed on the top of the cylinder cover 2, and the rotating rod 42 is rotatably installed on the top inner side of the cylinder cover 2. The shaft of the servo motor 41 is connected to the rotating rod 42 for transmission. Two sets of silicone plates 43 are fixedly installed on the outer surface of the rotating rod 42.

[0028] Working principle: Open the first flap 6, add tea leaves into the fermentation cylinder 1 through the feed pipe 5, close the first flap 6, connect the air inlet pipe 33 to the steam generator, the steam enters the spiral tube 31 through the air inlet pipe 33 and is ejected from each jet hole 32, and controls the servo motor 41 to start, drive the rotating rod 42 to rotate, and stir the tea leaves with the silicone plate 43. After the tea leaves have fermented, open the second flap 8 to discharge the steam through the exhaust pipe 7, open the discharge cover 10 to collect the tea leaves, and spirally remove the cylinder cover 2 along with the stirring mechanism 4 to clean it and the inside of the fermentation cylinder 1.
