Description

Technical Field

[0001] This utility model relates to the field of jujube bud tea production and processing technology, and in particular to a jujube bud tea fixation device with a layered structure. Background Technology

[0002] Jujube bud tea has high health value due to its rich content of various bioactive substances. It is a health tea made from the tender buds of jujube trees through processes such as picking, fixing, rolling and drying. Fixing is a key step in the production process. During the fixing process, the fresh jujube buds are quickly treated at high temperature to deactivate their internal enzymes and stabilize the quality of the tea. For example, patent CN222217095U discloses a jujube bud tea fixing device, including a fixing tank. An annular sliding assembly is provided on the inner wall of the fixing tank, and a mesh inner cylinder is provided inside the annular sliding assembly. A frame is fixedly connected to one side of the fixing tank, and a drive assembly for driving the mesh inner cylinder to rotate is provided on the frame. A dehumidification box one and a dehumidification box two are respectively provided on one side of the fixing tank, at the top and bottom of the drive assembly. In this jujube bud tea fixing device, during the hot air internal circulation process for fixing jujube buds and leaves, the water vapor in the hot air is first absorbed and filtered by a water-absorbing sponge, which can significantly reduce the moisture content in the hot air. This results in less water vapor flowing into the dehumidification box one, preventing the desiccant from becoming ineffective due to excessive water absorption in a short period, greatly improving the service life of the desiccant, avoiding frequent desiccant replacement, and improving processing efficiency. While the aforementioned jujube bud tea fixation device can first absorb and filter moisture from the hot air using an absorbent sponge, significantly reducing the moisture content of the hot air and resulting in less moisture flowing into the dehumidification chamber, thus preventing the desiccant from becoming ineffective due to excessive moisture absorption in a short period, greatly extending the desiccant's lifespan, avoiding frequent desiccant replacements, and improving processing efficiency, it uses a single-tank fixation structure for direct heating. Single-tank direct heating lacks a pre-fixation treatment step, resulting in high fixation pressure and energy consumption. It requires a one-time high-temperature inactivation of enzyme activity, which can easily lead to incomplete enzyme inactivation and overheating that damages nutrients. Therefore, a jujube bud tea fixation device with a layered structure needs to be designed. Utility Model Content

[0003] The purpose of this invention is to provide a jujube bud tea fixation device with a layered structure, in order to solve the defects of existing jujube bud tea fixation devices, such as high fixation pressure and poor processing effect.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a jujube bud tea fixing device with a layered structure, including a support frame; The top of the inside of the support frame is fixed with a downward-sloping primary blanching box. The inside of the downward-sloping primary blanching box is evenly provided with a single layer of guide plate, and far-infrared heating tubes are evenly installed on the single layer of guide plate. The bottom of the support frame is fixed with a drive mechanism. The output end of the drive mechanism is connected to a self-rotating secondary blanching tank. A second docking solenoid valve and a first docking solenoid valve are respectively installed on the self-rotating secondary blanching tank and the downward-sloping primary blanching box. The support frame is equipped with a dehumidifying circulating heating mechanism, which includes a heating box and a guide plate fixed to one side of the support frame in sequence. A gas discharge pipe and a gas inlet pipe extending into the self-rotating secondary blanching tank are fixed to the guide plate in sequence. An air pump is installed between the gas inlet pipe and the heating box, and a dehumidifying box is installed between the gas discharge pipe and the heating box.

[0005] Furthermore, three single-layer guide plates are provided, a vibration motor is installed on the outer wall of the downward-sloping primary blanching box, and a layered feeding port matching the single-layer guide plates is provided on the top of the downward-sloping primary blanching box.

[0006] Furthermore, the vertical center lines of the first docking solenoid valve and the second docking solenoid valve are on the same vertical line, and both the bottom of the first docking solenoid valve and the top of the second docking solenoid valve are provided with rubber sealing layers.

[0007] Furthermore, the drive mechanism includes a housing fixed to the support frame, and a stepper motor is mounted on the outer wall of the housing, with the output end of the stepper motor connected to a drive gear.

[0008] Furthermore, the top of the drive gear is meshed with a driven gear that is fixed to the self-rotating secondary blanching tank, and both the drive gear and the driven gear are movably connected to the inside of the housing through bearings. An incremental angle encoder is installed between the driven gear and the self-rotating secondary blanching tank.

[0009] Furthermore, a hollow bearing is provided between the side of the self-rotating secondary blanching tank away from the drive mechanism and the guide plate. Silicone branch pipes are uniformly provided on both the gas discharge pipe and the gas inlet pipe, and a filter cloth layer is provided inside the silicone branch pipe.

[0010] Furthermore, the interior of the dehumidification box is filled with a layer of calcium oxide filler, and the two sides of the dehumidification box are connected to the gas exhaust pipe and the heating box respectively through flanges to form a disassembly and installation structure.

[0011] Furthermore, a temperature sensor and a mesh heating wire are sequentially installed inside the heating box.

[0012] Furthermore, a one-way valve is installed on the gas discharge pipe.

[0013] The present invention provides a jujube bud tea fixation device with a layered structure, the advantages of which are: Equipped with a self-rotating two-stage withering tank, the downward-sloping first-stage withering box uses three single-layer guide plates to achieve layered spreading of buds and leaves. Combined with far-infrared heating tubes and the vibration of a vibrating motor to assist the downward movement, this ensures that each layer of buds and leaves receives heat from all directions. Layered preheating withering can initially inactivate some enzymes. The self-rotating two-stage withering tank, driven by a mechanism, rotates, allowing the buds and leaves to tumble gently within the tank, ensuring even heating and resulting in a more uniform color and taste in the finished product, thus improving the quality of the withering process. Furthermore, the two-stage processing structure enables gradient processing of jujube bud tea withering, improving the uniformity of withering. Additionally, a dehumidification system is activated. The air pump on the circulating heating mechanism extracts the hot and humid gas from the self-rotating secondary blanching tank through the gas discharge pipe. The hot and humid gas enters the dehumidification box, where it is adsorbed by the internal calcium oxide packing layer. The dried gas then enters the heating box, where the mesh heating wires and temperature sensor control the temperature of the dried gas. The heated gas is then returned to the self-rotating secondary blanching tank through the gas inlet pipe, forming a closed-loop cycle of dehumidification, drying, heating, and resupply. The constant temperature heating and gas circulation structure eliminates the need for continuous discharge of hot and humid gas and introduction of cold air, reducing heat loss and achieving energy-saving and efficient blanching. With a driven gear, the stepper motor on the drive mechanism starts, and the output gear drives the driven gear to rotate, which in turn drives the self-rotating secondary blanching tank to rotate. The incremental angle encoder can detect the rotation angle and speed of the self-rotating secondary blanching tank in real time and feed it back to the control system to precisely adjust the output speed of the stepper motor. This allows the buds and leaves to tumble gently in the tank, which helps to avoid product breakage and has the functions of enzyme inactivation blanching and bud and leaf shaping protection.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-5 The present invention provides a jujube bud tea fixation device with a layered structure, including a support frame 1.

[0018] Reference Figures 1-5 The top of the support frame 1 is fixed with a downward-sloping first-stage blanching box 4. The interior of the downward-sloping first-stage blanching box 4 is evenly provided with a single-layer guide plate 11. Far-infrared heating tubes 9 are evenly installed on the single-layer guide plate 11. The bottom of the support frame 1 is fixed with a drive mechanism 3. The output end of the drive mechanism 3 is connected to a self-rotating secondary blanching tank 2. The self-rotating secondary blanching tank 2 and the inclined downward primary blanching box 4 are respectively equipped with a second docking solenoid valve 10 and a first docking solenoid valve 8. A dehumidifying circulating heating mechanism 7 is installed on the support frame 1. The dehumidifying circulating heating mechanism 7 includes a heating box 703 and a guide plate 707 that are fixed to one side of the support frame 1 in sequence. A gas discharge pipe 709 and a gas inlet pipe 710 extending into the self-rotating secondary blanching tank 2 are fixed to the guide plate 707 in sequence. A vacuum pump 708 is installed between the gas inlet pipe 710 and the heating box 703. A dehumidifying box 702 is installed between the gas discharge pipe 709 and the heating box 703. There are 3 single-layer guide inclined plates 11. The outer wall of the downward-sloping primary blanching box 4 is equipped with a vibration motor 5, and the top of the downward-sloping primary blanching box 4 is equipped with a layered feeding port 6 that matches the single-layer guide inclined plates 11. The vertical center line of the first docking solenoid valve 8 and the vertical center line of the second docking solenoid valve 10 are on the same vertical line, and the bottom of the first docking solenoid valve 8 and the top of the second docking solenoid valve 10 are both provided with rubber sealing layers. The heating chamber 703 is equipped with a temperature sensor 704 and a mesh heating wire 705 in sequence. A one-way valve 712 is installed on the gas discharge pipe 709.

[0019] With an external power supply, the fresh jujube buds are fed into the layered feeding port 6 at the top of the downward-sloping primary blanching box 4. The fresh jujube buds are then evenly fed into three single-layer guide inclined plates 11, achieving layered spreading of the buds and leaves and avoiding stacking. At the same time, the far-infrared heating tubes 9 on the single-layer guide inclined plates 11 are activated, releasing far-infrared rays to gently heat each layer of buds and leaves. Meanwhile, the vibration motor 5 is activated, using slight vibration to assist the buds and leaves to slowly slide down the single-layer guide inclined plates 11, ensuring that each layer of buds and leaves is fully exposed to far-infrared rays, completing the layered preheating blanching effect, initially inactivating some enzyme activity and evaporating surface moisture.

[0020] With an external power supply, the self-rotating secondary blanching tank 2 achieves self-rotation through the drive mechanism 3, allowing the buds and leaves to tumble gently inside the tank, ensuring even heating and resulting in a more uniform color and taste in the finished product, thus improving the quality of blanching. Simultaneously, the suction pump 708 on the dehumidifying circulating heating mechanism 7 extracts the hot and humid gas from the self-rotating secondary blanching tank 2 through the gas discharge pipe 709. The one-way valve 712 on the gas discharge pipe 709 prevents gas backflow. The hot and humid gas then enters the dehumidification box 702, where it is absorbed by the internal calcium oxide filler layer 706. The drying gas enters the heating chamber 703. The mesh heating wire 705 inside the heating chamber 703, together with the temperature sensor 704, can control the temperature of the drying gas and ensure that the gas temperature is stable within the range required for blanching. The heated drying gas is then returned to the self-rotating secondary blanching tank 2 through the gas inlet pipe 710, forming a closed loop of dehumidification, drying, heating and resupply. The constant temperature heating and gas circulation structure eliminates the need for continuous discharge of hot and humid gas and introduction of cold air, reducing heat loss and achieving energy-saving and efficient blanching.

[0021] Reference Figures 1-3 The drive mechanism 3 includes a housing 305 fixed to the support frame 1, and a stepper motor 301 is installed on the outer wall of the housing 305. The output end of the stepper motor 301 is connected to the drive gear 302. The top of the drive gear 302 is meshed with a driven gear 303 that is fixed to the self-rotating secondary blanching tank 2. Both the drive gear 302 and the driven gear 303 are movably connected to the inside of the housing 305 through bearings. An incremental angle encoder 304 is installed between the driven gear 303 and the self-rotating secondary blanching tank 2. A hollow bearing is provided between the side of the self-rotating secondary blanching tank 2 away from the drive mechanism 3 and the guide plate 707. Silicone branch pipes 711 are evenly provided on both the gas discharge pipe 709 and the gas inlet pipe 710, and a filter cloth layer is provided inside the silicone branch pipe 711. The interior of the dehumidification box 702 is filled with a calcium oxide filler layer 706, and the two sides of the dehumidification box 702 are connected to the gas exhaust pipe 709 and the heating box 703 respectively through flanges 701 to form a disassembly and installation structure.

[0022] When an external power supply is connected, the stepper motor 301 on the drive mechanism 3 starts, and the active gear 302 at its output end drives the driven gear 303 to rotate, thereby driving the self-rotating secondary blanching tank 2 to rotate. The incremental angle encoder 304 can detect the rotation angle and speed of the self-rotating secondary blanching tank 2 in real time and feed it back to the control system to precisely adjust the output speed of the stepper motor 301, so that the buds and leaves can roll gently in the tank, which helps to avoid product breakage and has the functions of enzyme activity inactivation blanching and bud and leaf shaping protection.
