Description

Technical Field

[0001] This utility model relates to the field of tea processing technology, specifically a ventilation system for a row-type tea fermentation room. Background Technology

[0002] Tea fermentation is a crucial step in the production process, directly affecting the aroma, taste, and quality of the tea. Traditional fermentation rooms often rely on natural ventilation or simple mechanical ventilation, which can lead to uneven airflow distribution, causing over- or under-fermentation in some areas and affecting the consistency of tea quality.

[0003] Patent CN218942191U discloses a row-type ventilation system for tea fermentation rooms, including a mounting frame, a ventilation mechanism, and a rotating mechanism. A mounting box is fixedly mounted on the top of the mounting frame. The ventilation mechanism, located inside the mounting box, includes a fan and a duct. A support plate is fixedly mounted on the inner side of the mounting frame, and a fan is fixedly mounted on the top of the support plate. The output end of the fan is fixedly connected to a duct. This row-type tea fermentation room ventilation system can rotate the mounting frame by controlling the start of a motor, thus rotating the tea leaves placed on the frame, reducing obstruction of the tea leaves and facilitating even ventilation. It can also illuminate the tea leaves by controlling the lighting, and allows observation of the tea leaves inside the device through a glass panel, facilitating control of the fermentation time and preventing fermentation failure.

[0004] While the existing technology can improve ventilation by driving the placement rack to rotate via a motor, the fact that multiple placement racks are fixedly installed between two rotating rods makes it very inconvenient to take out and put in tea leaves, thus affecting the efficiency of tea leaf taking out and putting in. In view of this, we propose a row-type ventilation system for tea fermentation rooms. Utility Model Content

[0005] The purpose of this invention is to provide a ventilation system for a row of tea fermentation rooms to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A ventilation system for a tea fermentation room includes a fermentation box for placing and fermenting tea leaves, which is the main structure of the system. A door is hinged to the operating opening on the front side of the fermentation box for easy opening and closing. A rotating rod is rotatably connected between the upper and lower sides of the inner wall of the fermentation box, supporting and driving the rotation of support frames. A motor is installed at the bottom of the fermentation box to drive the rotating rod. The motor is powered by an external power source. Multiple support frames are arranged equidistantly on the rotating rod, and the rotating rod drives these support frames to rotate. Each support frame includes an annular block fixedly connected to the outer wall of the rotating rod. Multiple connecting rods are arranged in a circular array on the outer wall of the annular block. The outer ends of the multiple connecting rods are connected to an annular support plate. Multiple circular holes are opened at the top of the annular support plate. The annular support plate, together with the multiple connecting rods, supports the hollowed-out placement tray.

[0008] A perforated placement tray is placed on top of the support frame. The outer wall of the perforated placement tray has a U-shaped opening to avoid the connecting rod. At the bottom of the perforated placement tray and near the outer edge, there are multiple positioning posts arranged in a circular array. The multiple positioning posts are respectively inserted into multiple circular holes, so that the perforated placement tray can rotate with the support frame. When the perforated placement tray is placed on the support frame, it is first placed between two adjacent support frames, and then the perforated placement tray is moved backward until the end of the inner wall of the U-shaped opening abuts against the outer wall of the connecting rod. Then the perforated placement tray is moved downward so that the multiple positioning posts are respectively inserted into the multiple circular holes, thereby realizing the placement of the perforated placement tray, which makes it convenient for staff to pick up and put down the perforated placement tray, and thus convenient for staff to pick up and put down tea leaves.

[0009] An exhaust vent is located on the top right side of the fermentation box, with a dustproof screen inside to allow air to escape. A partition is located inside the fermentation box, near the left side. A ventilation duct is located on the left side of the partition, comprising a fixed vertical pipe. Multiple fixed longitudinal pipes are arranged vertically at equal intervals on the rear side of the outer wall of the fixed vertical pipe. Multiple air outlet branch pipes are arranged horizontally at equal intervals on the right side of the outer wall of the fixed longitudinal pipe. The output end of each air outlet branch pipe passes through the left side of the partition. An airflow generating assembly is located at the bottom of the fermentation box, comprising a circular pipe containing a fan powered by an external power source. The circular pipe is connected to the fixed vertical pipe via a duct. Airflow is generated by the fan, passing sequentially from the duct and the fixed vertical pipe into the multiple fixed longitudinal pipes, and finally exiting through the multiple air outlet branch pipes. This creates a horizontal, right-facing airflow within the fermentation box, thereby ventilating the tea leaves on the multiple perforated trays arranged in a row for fermentation.

[0010] Preferably, a strip lamp is provided on the right side of the inner wall of the fermentation box. The strip lamp is powered by an external power source and is used for lighting inside the box. A transparent observation window is provided on the front side of the box door to facilitate observation of the tea leaves inside the fermentation box.

[0011] Preferably, the airflow generating component further includes a rectangular shell, the top of which is fixedly connected to the bottom of the fermentation tank, a plurality of air inlets are provided on the rear side of the rectangular shell, the rear end of the circular tube is fixedly connected to the front side of the rectangular shell, and the rectangular shell is in communication with the circular tube.

[0012] Preferably, a first U-shaped limiting plate is provided on the upper and lower sides of the inner wall of the rectangular shell and near the rear side. A first filter plate is slidably connected between the two first U-shaped limiting plates for preliminary filtration of particulate matter in the air. The left side of the first filter plate penetrates through the inner wall of the rectangular shell to the outside, making it convenient for workers to install and remove the first filter plate.

[0013] Preferably, a second U-shaped limiting plate is provided on both the upper and lower sides of the inner wall of the rectangular shell and near the front side. A second filter plate is slidably connected between the two second U-shaped limiting plates. The left side of the second filter plate penetrates through the inner wall of the rectangular shell to the outside, which facilitates the installation and removal of the second filter plate by the operator. The filter hole size of the second filter plate is smaller than that of the first filter plate. The second filter plate provides further air filtration.

[0014] Preferably, the sum of the heights 'a' of the hollow placement plate and the positioning column is less than the distance 'b' between the two adjacent support frames, ensuring that workers can move the hollow placement plate up and down and easily assemble and disassemble it.

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

[0016] 1. This row-type tea fermentation room ventilation system uses a motor to drive the rotating rod and support frame to rotate, so that the tea leaves are evenly exposed to air on the hollow placement tray, improving the uniformity of fermentation and avoiding the problem of uneven airflow distribution caused by traditional ventilation methods.

[0017] 2. The ventilation system of this row-type tea fermentation room adopts a flexible support frame and hollow placement tray design, which can easily disassemble and assemble the hollow placement tray, making it convenient for staff to take and put tea leaves, solving the problem of inconvenience in taking and putting tea leaves in the traditional system and improving work efficiency.

A motor 6 is provided at the bottom of the fermentation box 1 to drive the rotating rod 3 to rotate. The motor 6 is powered by an external power source and drives the rotating rod 3 to rotate. Multiple support frames 4 are provided on the rotating rod 3 in an equidistant arrangement. The rotating rod 3 drives the multiple support frames 4 to rotate. The support frame 4 includes an annular block 40 fixedly connected to the outer wall of the rotating rod 3.

A dustproof screen is installed inside the exhaust vent 10 to allow air to escape from the fermentation chamber 1. A partition 11 is located inside the fermentation chamber 1, near the left side. A ventilation duct 7 is located on the left side of the partition 11. The ventilation duct 7 includes a fixed vertical pipe 70. Multiple fixed longitudinal pipes 71 arranged vertically at equal intervals are located on the rear side of the outer wall of the fixed vertical pipe 70. Multiple air outlet branch pipes 72 arranged horizontally at equal intervals are located on the right side of the outer wall of the fixed longitudinal pipes 71. The output end of the air outlet branch pipes 72 passes through the left side of the partition 11. The bottom of the box 1 is equipped with an airflow generating component 8, which includes a circular pipe 83 and a fan 84 inside the circular pipe 83. The fan 84 is powered by an external power source. The circular pipe 83 is connected to a fixed vertical pipe 70 through an air guide pipe 85. The fan 84 generates airflow, which passes through the air guide pipe 85 and the fixed vertical pipe 70 in sequence into multiple fixed vertical pipes 71, and finally exits from multiple air outlet branch pipes 72. This generates a horizontal rightward airflow in the fermentation box 1, thereby ventilating the tea leaves on the multiple hollowed-out trays 5 arranged in a row for fermentation.

[0036] In this embodiment, a strip lamp 9 is provided on the right side of the inner wall of the fermentation box 1. The strip lamp 9 is powered by an external power source and is used for lighting inside the box. A transparent observation window is provided on the front side of the box door 2 to facilitate observation of the tea leaves inside the fermentation box 1.

[0037] Specifically, the airflow generating component 8 also includes a rectangular housing 80, the top of which is fixedly connected to the bottom of the fermentation tank 1, and multiple air inlets 800 are provided on the rear side of the rectangular housing 80. The rear end of the circular tube 83 is fixedly connected to the front side of the rectangular housing 80, and the rectangular housing 80 is connected to the circular tube 83.

[0038] Furthermore, a first U-shaped limiting plate 801 is provided on the upper and lower sides of the inner wall of the rectangular shell 80 and near the rear side. A first filter plate 81 is slidably connected between the two first U-shaped limiting plates 801 for preliminary filtration of particulate matter in the air. The left side of the first filter plate 81 penetrates the inner wall of the rectangular shell 80 to the outside, making it convenient for workers to install and remove the first filter plate 81.

[0039] Furthermore, a second U-shaped limiting plate 802 is provided on the upper and lower sides of the inner wall of the rectangular housing 80, near the front. A second filter plate 82 is slidably connected between the two second U-shaped limiting plates 802. The left side of the second filter plate 82 penetrates the inner wall of the rectangular housing 80 to the outside, making it convenient for workers to install and remove the second filter plate 82. The filter hole size of the second filter plate 82 is smaller than that of the first filter plate 81, and the second filter plate 82 provides further air filtration.

[0040] Furthermore, the sum of the heights 'a' of the hollow placement plate 5 and the positioning column 51 is less than 'b' with the distance 'b' between the two adjacent support frames 4, ensuring that the staff can move the hollow placement plate 5 up and down and smoothly assemble and disassemble it.

[0041] In this embodiment, the ventilation system for the row-type tea fermentation room is used by opening the fermentation box door 2, evenly spreading the tea leaves to be fermented on the perforated placement tray 5, placing the perforated placement tray 5 on the support frame 4, moving the perforated placement tray 5 to avoid the connecting rod 41, and inserting the positioning pin 51 into the circular hole 420 for fixation, closing the box door 2, and turning on the motor 6 and the fan 84. The motor 6 drives the rotating rod 3 and the support frame 4 to rotate, causing the tea leaves to rotate with the perforated placement tray 5. The fan 84 generates airflow, which passes through the air guide pipe 85 and the fixed vertical pipe 70 in sequence into multiple fixed vertical pipes 71, and finally exits from multiple air outlet branches. Pipe 72 outputs a horizontal, right-facing airflow within the fermentation chamber 1, thereby ventilating the tea leaves on the multiple perforated trays 5 arranged in a row for fermentation. This ensures the tea leaves receive adequate ventilation. The fermentation status of the tea leaves can be observed in real time through the strip lights 9 and the transparent observation window. After fermentation is complete, the system is shut down, the chamber door 2 is opened, and the perforated trays 5 are removed, allowing staff to quickly retrieve the fermented tea leaves. The first filter plate 81 and the second filter plate 82 inside the rectangular casing 80 are regularly inspected and replaced to ensure the cleanliness of the air entering the system. In this way, the system can effectively improve the uniformity and quality of tea fermentation.
