Abstract
Description
Technical Field
[0001] This invention relates to the field of tea processing technology, specifically to an intelligent tea brick machine. Background Technology
[0002] The production process of tea bricks generally includes picking, withering, rolling, fermentation, steaming, pressing, and drying. Existing intelligent tea brick machines, such as the WT-II automatic tea brick pressing machine manufactured by Ya'an Wantong Pipe Industry Co., Ltd., include air, pneumatic, steam, conveying, weighing, and hydraulic systems, enabling the automatic integration of steaming and pressing processes. The process involves placing fermented tea leaves into a funnel in a steam pipe. The tea leaves fall evenly onto a conveyor belt within the steam pipe, which transports them towards the hydraulic equipment. During this process, the tea leaves are steamed, softening them. The conveyor belt delivers a fixed quantity of tea leaves to the mold in the hydraulic equipment, where it presses the tea leaves into tea bricks. Workers then remove the pressed tea bricks for the next drying step.
[0003] During tea steaming, a large amount of steam and heat enters the workshop through the opening at the end of the steam pipe near the hydraulic equipment. The steam also contains tea dust. Prolonged inhalation of this tea dust can lead to tea pneumoconiosis, posing a health hazard to workers. Therefore, existing workshops are equipped with dust and air extraction systems to remove the heat, steam, and tea dust generated during tea steaming. The extraction capacity of these systems is typically 7000 m³ / h. 3 The system operates at a rate of / h, ensuring the safety of workers in the workshop. However, the heat and steam drawn away by the suction equipment are directly released into the air, resulting in low utilization of water and heat resources and high production costs.
[0004] To address this, an intelligent tea brick machine is proposed. This machine automatically recovers some steam and filters out tea dust during the steaming process, while reusing the recovered steam to further steam the tea. This improves the utilization rate of water vapor and heat, reduces water and energy consumption, and lowers the production cost of tea bricks. Summary of the Invention
[0005] The purpose of this invention is to provide an intelligent tea brick machine that improves the utilization rate of water resources and heat, and reduces the production cost of the intelligent tea brick machine by recovering part of the water vapor, filtering out tea dust in the water vapor, and then reusing the water vapor for steaming tea, thereby solving the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A smart tea brick machine includes:
[0008] A steam pipe is arranged at an incline. A funnel is fixedly installed on the top wall of the lower end of the steam pipe. A conveyor belt device is installed inside the steam pipe. A gas delivery pipe is connected to the lower end of the steam pipe. A material outlet is opened at the higher end of the steam pipe.
[0009] A forming device is provided on the material outlet side of the steam pipe, and the forming device is used to form steamed tea leaves into tea bricks.
[0010] Also includes:
[0011] A circulation pipe is installed on the top wall of the steam pipe, with one end of the circulation pipe connected to the top wall of the steam pipe near the material outlet. The other end of the circulation pipe is connected to a filter unit for filtering tea dust in the water vapor. The end of the filter unit away from the circulation pipe is equipped with an air intake unit for drawing water vapor from the material outlet into the circulation pipe. The end of the air intake unit away from the filter unit is equipped with a heating unit for intercepting part of the water vapor condensing into water flow and reheating the water flow to form water vapor. The heating unit can increase the evaporation efficiency of the water flow. The other end of the heating unit is connected to the top wall of the steam pipe near the funnel.
[0012] Existing intelligent tea brick machines require opening the gas supply pipe beforehand to pump steam into the steam pipe until it is full of steam, typically indicated by a large amount of steam escaping from the material outlet. Afterward, the operator starts the forming device and conveyor belt, then pours the fermented tea leaves into a funnel. The funnel is not directly connected to the steam pipe; a feeding device exists between the funnel and the steam pipe. This feeding device is linked to the conveyor belt. When the conveyor belt is running, the feeding device allows some tea leaves to fall onto the conveyor belt, ensuring a relatively even distribution. The tea leaves on the conveyor belt are steamed by high-temperature steam, gradually softening them and preparing them for subsequent pressing and shaping. The conveyor belt device works in conjunction with the forming device. When the forming device moves the empty mold to below the material outlet of the steam pipe, the conveyor belt device starts and transports the tea leaves into the mold. When the weighing system of the forming device senses that the weight of the tea leaves in the mold has reached the set value, the conveyor belt device stops. The forming device moves the mold filled with tea leaves to the stamping area and at the same time moves a new empty mold to below the material outlet of the steam pipe.
[0013] Existing intelligent tea brick machines directly release water vapor into the workshop. This water vapor contains a large amount of heat and 0.7-0.8 g / m³ of oxygen. 3 To eliminate tea dust, existing tea brick workshops are equipped with air extraction equipment to remove the impact of water vapor and tea dust on production. This equipment has an air extraction capacity of 7000 m³ / h. 3 / h. The water vapor that is drawn in is filtered and then directly released into the outside air. This results in a large amount of water vapor and heat not being fully utilized, leading to high production costs for the steaming process of tea bricks.
[0014] Therefore, this invention installs a circulation pipe on the top wall of the steam pipe, with one end of the circulation pipe connected to the top wall of the steam pipe near the material outlet. The suction unit then draws some water vapor into the circulation pipe. The water vapor entering the circulation pipe passes through a filter unit, which removes tea dust. Since there is no continuous heating and the filter element blocks the flow, most of the water vapor becomes water. The water vapor and water then enter the suction pipe, which provides suction to the circulation pipe, drawing some water vapor from the material outlet of the steam pipe into the circulation pipe, reducing water vapor loss within the workshop. The water vapor and water flowing through the suction pipe enter the heating pipe, which reheats the water into steam. The other end of the heating pipe is connected to the top wall of the steam pipe near the funnel. Under the action of the suction pipe, the water vapor in the heating pipe enters the steam pipe to steam the tea leaves. Compared to heating water at room temperature to 100°C to turn it into steam, the water flowing through the heating pipe still retains a significant amount of heat. Therefore, the amount of heat required to heat the water to 100°C is much less. Thus, this invention not only saves water resources but also reduces energy consumption and lowers the production cost of the intelligent tea brick machine. Verification has shown that this invention increases water resource utilization by 45% and reduces production costs by 5%.
[0015] Preferably, a portion of the pipe at the point where the circulation pipe connects to the steam pipe is perpendicular to the ground.
[0016] To reduce the intake of external gases into the steam pipe through the circulation pipe and increase the intake of water vapor-containing gases into the steam pipe, thus preventing a large influx of cold air into the circulation pipe that would cause rapid cooling of the water vapor and waste of heat, this invention tilts the steam pipe closer to the funnel, creating an obtuse angle between the intake direction of the circulation pipe and the forward direction of the conveyor belt. This increases the intake of gases into the steam pipe. Since the steam pipe of the WT-II automatic tea brick pressing machine is inclined, the section of pipe at the connection point between the circulation pipe and the steam pipe can be perpendicular to the ground. A bend design is used at the corners of the circulation pipe to reduce the loss of kinetic energy when the water vapor encounters resistance during its movement.
[0017] Preferably, the filtration unit includes a filtration pipe installed at one end of a circulation pipe. A housing is located in the middle of the filtration pipe. An opening groove is formed on the side wall of the housing. Guide rails are symmetrically installed on the side wall of the opening groove perpendicular to the axis of the filtration pipe. A spring is installed on the side wall of the opening groove away from the opening, facing the opening. A movable groove is symmetrically formed on the side wall of the opening groove. A slanted slider is movably installed in the movable groove via a spring. A frame is slidably installed in the opening groove. A filter element is located within the frame. A sliding groove that mates with the guide rails is formed on the frame. Slanted sliders are symmetrically fixedly installed on the side wall of the frame. A slanted slider is slidably installed on the side wall of the frame where the slanted sliders are installed. A spring is installed on the side of the slanted sliders away from the slanted sliders, and the directions of the slanted sliders are opposite to those of the slanted sliders. The length of the slanted slider is greater than that of the slanted slider. A sealing unit is installed on the side wall of the frame away from the spring.
[0018] Here, a filter element filters out tea dust from the steam in the filtration pipe, preventing the tea dust from circulating and accumulating in the steam pipe and affecting the quality of the tea during steaming. Therefore, the filtration pipe of this invention has a housing in the middle for installing the filter element. The housing has an opening groove, and the two sides of the opening groove are connected to the pipe. The opening groove is used for installing and removing the filter element. Considering the convenience of workers when installing and removing the filter element, the opening groove is optimally oriented horizontally.
[0019] When installing the filter element, the operator holds the handle on the side wall of the frame to align the guide rail with the slide groove. Then, the frame and filter element are pushed into the opening groove. The side wall of the opening groove, which connects to the pipe, has a transition fit with the frame to reduce the entry of water vapor and water flow into the opening groove. When the operator pushes the frame close to the bottom wall of the opening groove, the side wall of the frame will contact spring one. At this point, pushing the frame requires overcoming the resistance of spring one. The operator continues to push the frame until the inclined surface of inclined slider two presses against the inclined surface of inclined slider one. At this point, inclined slider one, under the action of inclined slider two, overcomes spring two and enters the movable groove. After inclined slider two passes through the movable groove, inclined slider one, under the action of spring two, extends back out of the movable groove, making a striking sound. Once the operator hears the sound, they can release the handle. At this point, inclined slider one and inclined slider two are vertically aligned under the action of spring one, thus locking the frame in the opening groove. The sealing unit on the frame will then seal the opening groove, preventing water vapor leakage and waste. When the steam pipe is working, the water vapor drawn in from the circulation pipe will pass through the filter element. Since the water vapor entering the circulation pipe is no longer continuously heated, and since the filter element is a PP melt-blown filter element or other water purification filter element with a maximum filtration accuracy of only 60μm, most of the water vapor will be blocked and accumulated after passing through the filter element, and eventually become water flow. The water flow will continue to flow downward along the pipe.
[0020] Before starting the machine each day, staff need to remove the filter element to check for blockages and ensure it can continue to be used. When removing the filter element, staff need to push the handle to move the frame into the opening slot until the vertical surface of the inclined slider three pushes the inclined slider one into the movable slot. After the inclined slider three passes through the movable slot, the inclined slider one extends out of the movable slot under the action of spring two, making a striking sound. Once the staff hears the sound, they can pull the handle to pull the filter element out of the opening slot. At this point, the inclined surface of the inclined slider three will contact the vertical surface of the inclined slider one. Because the spring constant of spring three is less than that of spring two, when the frame moves away from the opening slot, the inclined surface... Slider three will move closer to inclined slider two and eventually fit together with it. At this point, since inclined slider three can no longer move, it will push inclined slider one to overcome spring two and enter the movable groove. Because the length of inclined slider three is greater than that of inclined slider two, when inclined slider three passes through the movable groove, the protruding inclined slider one will not be embedded in the gap between inclined slider three and inclined slider two, but will act directly on inclined slider two. At this point, the operator can completely disassemble the frame for inspection. If the filter element is found to be severely clogged and unusable, it can be cleaned or replaced. After the frame is disassembled, inclined slider three returns to its initial position under the action of spring three.
[0021] The filter unit can also use a Y-type filter for filtration. The Y-type filter has a simple structure and lower cost, but the process of disassembling the filter element is more complicated and it is not suitable for frequent disassembly.
[0022] Preferably, the space for installing the filter element on the frame is circular, and the diameter of the circle is equal to the inner diameter of the filter pipe.
[0023] The filter element is made into a circle with the same inner diameter as the filter pipe, allowing the water vapor entering the filter pipe to fully contact the filter element, thus improving the filtration effect on tea dust. At the same time, it can prevent water vapor from turning into water and flowing to other areas of the filter element that are not in direct contact with water vapor, thus preventing it from flowing down into the air intake pipe and heating pipe in time, which would result in some water accumulating at the filter element and being wasted.
[0024] Preferably, the closing unit includes a guide rod installed on the side wall of the frame away from the spring and perpendicular to the side wall. A cover plate is slidably installed on the guide rod. A baffle is fixedly installed at the other end of the guide rod. A handle is installed at the end of the baffle away from the guide rod. A spring is installed between the cover plate and the baffle. A sealing ring is installed on the side of the cover plate away from the spring.
[0025] When the frame is not in the opening slot, the cover plate remains in contact with the frame under the action of spring four. Because the distance between the baffle and the cover plate is greater than the distance between the baffle and the side wall of the housing when the frame is fixed after entering the opening slot, when the frame is locked in the opening slot, the cover plate will move a certain distance towards the baffle under the action of the housing, overcoming the elastic force of spring four. Since a sealing ring is installed on the side of the cover plate away from the baffle, and a sealing ring is also installed between the cover plate and the guide rod, the cover plate will then completely seal the opening slot under the action of spring four, preventing water vapor leakage and waste. At this time, the handle is installed on the side of the baffle away from the guide rod.
[0026] Furthermore, an annular protrusion can be provided on the side of the cover plate near the frame, and an annular groove can be opened at the corresponding position on the housing. When the cover plate seals the opening slot, the annular protrusion engages with the annular groove, providing better positioning of the cover plate and preventing water vapor leakage due to the cover plate not corresponding to the opening slot. Alternatively, the guide rod can be made into a non-rotating structure, so that the cover plate cannot rotate relative to the guide rod when moving on it.
[0027] Preferably, a proximity switch for detecting whether the frame is installed in a set position is installed on the inner bottom wall of the opening slot, and the proximity switch is electrically connected to the gas pipeline valve.
[0028] If, due to operator error, the filter element is not installed in the opening slot or is not installed correctly, and the gas supply pipe valve is opened to supply steam into the steam pipe, and the motor also starts to drive the fan blades to extract air, most of the extracted steam will leave the filter pipe through the opening slot and drift into the workshop, causing the invention to fail. Therefore, a proximity switch is installed on the bottom wall inside the opening slot as a foolproof measure. When the filter element is installed correctly, the proximity switch is triggered, and only then can the gas supply pipe valve be opened; otherwise, it cannot be opened, thus preventing the invention from failing.
[0029] Preferably, the air intake unit includes an air intake pipe fixedly installed at the end of the filter pipe away from the circulation pipe, a bracket fixedly installed inside the air intake pipe, a motor fixedly installed on the bracket, a fan blade fixedly installed on the output end of the motor, a filter screen to prevent tea leaves from entering the circulation pipe installed at the end of the circulation pipe connected to the steam pipe, and the motor will periodically reverse for a set time.
[0030] The suction unit in this invention uses a motor to drive the fan blades to rotate, creating a negative pressure on the side of the fan blades near the filter pipe. This causes the circulating pipe to draw away the gas from the material outlet of the steam pipe. Simultaneously, pressure is applied to the side of the fan blades near the heating pipe, allowing water vapor from the heating pipe to enter the steam pipe, while preventing water vapor from the steam pipe from entering the heating pipe. Since this invention targets the steam pipe rather than the entire workshop, the suction capacity of this suction unit is 700-800 m³ / h.3 Therefore, a BLDC36 small geared motor with an output power of 30W and a speed of 960r / min can be used. Since the motor and fan blades are located after the filter pipe, they will not be affected by tea dust, but waterproofing is required to prevent water vapor from affecting them.
[0031] To prevent the suction force generated by the intake pipe from drawing tea leaves into the circulation pipe and causing blockage, a filter screen can be installed at the end where the circulation pipe connects to the steam pipe. This filter screen can be made of metal mesh or composite material mesh with large gaps. The filter screen can block tea leaves without affecting the flow of steam. When tea leaves are attracted, although they are blocked by the filter screen, they remain attached to it, affecting the intake unit's suction. Therefore, the motor can reverse at set intervals (0.5h-1h), the reversal time depending on the pipe volume. Reversing the motor switches the circulation pipe from suction to blowing, which blows away the tea leaves attached to the filter screen, preventing them from affecting the filter's permeability.
[0032] In addition to a fan, the intake unit can also use an air pump. The pump draws air in from the direction of the filter pipe and exhausts it towards the direction of the heating pipe. The pump can achieve greater power within a limited volume, but its continuity is poor and it is noisier. The choice should be made based on the actual production needs.
[0033] Preferably, the heating unit includes a heating pipe fixedly installed at the end of the air intake pipe away from the filter pipe. The heating pipe is zigzag-shaped, and part of the pipe is parallel to the ground. A heating component is installed in the horizontal part of the heating pipe, and a platform for stopping the water flow is provided on the bottom inner wall of the horizontal part of the heating pipe.
[0034] The inner diameters of the circulation pipe, power pipe, intake pipe, and heating pipe are all equal to prevent water vapor from accumulating in one place and unable to flow downwards after turning into water. To prevent the water flow rate from being too fast and causing the heating components in the heating pipe to be unable to reheat the water flow into water vapor, this invention sets the heating pipe section parallel to the horizontal plane. Since the intake unit has a very small effect on the water flow, when the water flow reaches the horizontal section of the heating pipe, it will stop there due to the loss of gravity. However, the inner bottom wall of this section of the pipe is flat, and there is a transition area between the flat surface and the other inner walls of the pipe. Therefore, the water flow will spread evenly and straight on it without accumulating, which increases the heating area of the water flow, accelerates the evaporation rate of the water flow, and under the action of the heating components, the water flow turns into water vapor. Then, under the action of the intake unit, it enters the steam pipe from the connection between the heating pipe and the steam pipe and is reused for steaming tea.
[0035] The heating element here can be a heating rod, heating resistance wire, etc. Since the water itself retains a lot of heat, the power of the heating element does not need to be too high, generally around 50W.
[0036] In addition to being arranged horizontally, heating pipes can also be arranged at an angle. In this way, the water flow will stop completely at the lowest point of the pipe, but the water will accumulate instead of being spread out in the pipe, which will affect the efficiency of the water flow evaporating into water vapor.
[0037] Preferably, the circulation pipe, filter pipe, air intake pipe and heating pipe are arranged at an angle, and the height of the circulation pipe is greater than that of the heating pipe.
[0038] Since most of the water vapor turns into water after passing through the filter element, the suction unit has a weak traction effect on the water flow, relying solely on gravity to keep it moving. Therefore, the circulation pipe, filter pipe, suction pipe, and heating pipe are all arranged at an angle, with the circulation pipe being taller than the heating pipe. Only in this way can the recovered water vapor be recycled. In this invention, the steam pipe itself is arranged at an angle, so the circulation pipe, filter pipe, suction pipe, and heating pipe only need to be parallel to it. However, if the steam pipe were horizontal, the circulation pipe, filter pipe, suction pipe, and heating pipe would need to be arranged at an angle independently.
[0039] Preferably, the outer walls of the circulation pipe, filter pipe, air intake pipe and heating pipe are provided with heat insulation material.
[0040] To reduce heat loss during the transport of water vapor and water flow in circulation pipes, filtration pipes, intake pipes, and heating pipes, one side of the outer wall of the circulation pipes, filtration pipes, intake pipes, and heating pipes is covered with insulation material, such as polyurethane, glass wool, asbestos, etc.
[0041] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0042] 1. The machine absorbs water vapor from the material outlet of the steam pipe through the suction unit and filters out tea dust from the water vapor through the filtration unit, preventing tea dust from circulating and accumulating in the steam pipe and affecting the quality of the tea during steaming. Then, the water vapor and some of the water vapor condensed into water are reheated and passed into the steam pipe for steaming tea. This improves the utilization rate of water vapor and heat by the intelligent tea brick machine, reduces the consumption of water resources and energy, and lowers the production cost of the intelligent tea brick machine.
[0043] 2. The coordinated movement of the inclined sliders allows operators to easily disassemble the filter element and frame by simply pushing and pulling them. This facilitates filter element inspection and replacement before the intelligent tea brick machine starts operating, preventing filter blockage that could clog the entire pipeline and result in recycled water vapor containing excessive tea dust, thus reducing the quality of the steamed tea. Therefore, this invention reduces the time required for operators to disassemble the frame and filter element, improving work efficiency.
[0044] 3. By establishing a predetermined angle at the connection between the circulation pipe and the steam pipe, the amount of gas drawn into the steam pipe by the circulation pipe is increased, while the amount of gas drawn into the steam pipe from outside the steam pipe is reduced. Since the temperature of the gas outside the steam pipe is low, the greater the amount of gas drawn in from outside the steam pipe, the greater the temperature drop of the recovered steam, resulting in heat waste. Therefore, this arrangement of the circulation pipe in this invention can further improve the utilization rate of recovered steam heat, reduce energy consumption, and lower production costs.

[0054] The following will be combined with the appendix of the present invention. Figures 1 to 8 The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the embodiments of the present invention include, but are not limited to, the embodiments described below. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0055] The terms "first" and "second" appearing in this application are used only to describe the order of objects and not to indicate relative importance or the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the stated features. The term "multiple" appearing in this application means at least two.
[0056] Example 1, Reference Figures 5 to 7 Before the intelligent tea brick machine starts, let's take the WT-Ⅱ tea brick automatic pressing and forming machine manufactured by Ya'an Wantong Pipe Industry Co., Ltd. as an example.
[0057] The worker holds handle 14 and pushes frame 12 5cm into opening slot 7. During this process, the vertical surface of inclined slider three 1103 pushes inclined slider one 1101 against spring two 902 into movable slot 10. After inclined slider three 1103 passes through movable slot 10, inclined slider one 1101 extends out of movable slot 10 again under the action of spring two 902, making a knocking sound. When the worker hears the sound, he can pull handle 14 to pull PP meltblown filter element 13 out of opening slot 7. At this time, the inclined surface of inclined slider three 1103 will contact the vertical surface of inclined slider one 1101. Since the spring constant of spring three 903 is 5N / m and the spring constant of spring two 902 is 10N / m, the spring constant of spring three 903... The spring constant is less than that of spring 902. Therefore, when frame 12 moves away from the opening slot 7, slider 1103 moves closer to slider 1102 and eventually fits against it. Since slider 1103 cannot move further, it pushes slider 1101 against spring 902 into the movable slot 10. When slider 1103 passes through the movable slot 10, the extended slider 1101 acts on slider 1102. At this point, the frame 12 can be completely disassembled for inspection. If the PP meltblown filter element 13 is found to be severely clogged and unusable, it can be cleaned or replaced. After frame 12 is disassembled, slider 1103 returns to its initial position under the action of spring 903.
[0058] After inspecting the PP meltblown filter element 13, the operator holds the handle 14 on the side wall of the frame 12, aligns the guide rail 8 with the slide groove, and then pushes the frame 12 and the PP meltblown filter element 13 into the opening groove 7. When the operator pushes the frame 12 17cm, the cover plate 16 will contact the outer wall of the housing 6. When the operator continues to push the frame 12, the cover plate 16 will overcome the resistance of the spring 904 and move closer to the handle 14. At this time, the side wall of the frame 12 will contact the spring 901. The pushing of the frame 12 needs to overcome the resistance of the spring 901. When the operator pushes the slider 18cm, the inclined surfaces of slider 1102 and slider 1101 press against each other. At this time, slider 1101, under the action of slider 1102, overcomes spring 902 and enters the movable groove 10. After slider 1102 passes through the movable groove 10, slider 1101, under the action of spring 902, extends out of the movable groove 10 again and makes a knocking sound. When the operator hears the sound, they can release handle 14. At this time, slider 1101 and slider 1102 are vertically aligned under the action of spring 901, so frame 12 is locked in the opening groove 7. Proximity switch 22 is triggered, the gas pipe valve can be opened, and cover plate 16 will completely close the opening groove 7. At this time, the intelligent tea brick machine can be started to produce tea bricks.
[0059] refer to Figures 1 to 4 as well as Figure 8 When the intelligent tea brick machine starts production.
[0060] The staff first opened the gas supply pipe, the BLDC36 mini geared motor, and the heating rod to fill the steam pipe 1 with steam. Since the steam pipe 1 only has one opening at the material outlet, the water vapor will drift towards the material outlet. The BLDC36 mini geared motor drives the fan blade 20 to rotate, creating a negative pressure on the side of the fan blade 20 near the filter pipe 5 and pressurizing the side of the fan blade 20 near the heating pipe 21. When the water vapor approaches the connection hole between the circulation pipe 4 and the steam pipe 1, the suction will draw some of the water vapor and outside air from the steam pipe 1 into the circulation pipe 4. The water vapor entering the circulation pipe 4 will enter the filter pipe 5 and be filtered by the PP melt-blown filter element 13. Since the water vapor entering the circulation pipe 4 is no longer continuously heated, most of the water vapor will turn into water after passing through the PP melt-blown filter element 13. The water will continue to flow down the filter pipe 5 into the air intake pipe 18. The water vapor and water entering the air intake pipe 18 will enter the heating pipe 21 along the pipe and eventually flow to the horizontal surface of the horizontal part of the heating pipe 21. Since the air intake unit has little effect on the water flow, when the water flow reaches the horizontal part of the heating pipe 21, it will stop here due to the loss of gravity. However, the inner bottom wall of this section of the pipe is flat, so the water will spread evenly on it and will not accumulate. Under the heating of the heating rod, the water flow will be heated to 100°C and turn back into water vapor. Then, under the action of the fan blade 20, the water vapor will enter the steam pipe 1 from the connection between the heating pipe 21 and the steam pipe 1 and be used again to steam the tea.
[0061] Five minutes later, the staff reduced the output of the gas supply pipe by 40%, then put the fermented tea leaves into funnel 2, and then started the conveyor belt device 3 and the forming device to produce tea bricks.
[0062] One hour later, the motor drives the fan blades 20 to reverse direction for 1 minute. This reversal creates a pressurized side of the fan blades 20 near the circulation pipe 4 and a negative pressure side on the other. At this time, the circulation pipe 4 will spray air into the steam pipe 1, blowing away any tea leaves that may be adhering to the filter screen 24, thus preventing the tea leaves from affecting the filter screen's permeability. After one minute, the motor resumes forward rotation.
[0063] Verification has shown that this invention increases water resource utilization by 45% and reduces production costs by 5%.
