Description

Technical Field

[0001] The invention relates to the technical field of scented tea processing, and in particular to scented tea scenting equipment. Background Art

[0002] The traditional scenting process of scented tea includes mixing camellia, scenting, opening, picking, and drying. For multiple scenting processes, the process is repetitive and cumbersome; manual operation is labor-intensive and has high production costs. For example, scenting requires manual stacking of camellia; opening requires manual thinning of camellia to dissipate heat; picking requires manual feeding of vibrating screens. The timing of opening is often based on the fixed interval scenting time, which is unreliable. Public literature also reports some technologies about scenting equipment for scented tea, such as:

[0050] 1. Technical principle of the scented tea scenting equipment of the present invention

[0051] 1. Structural design

[0052] The bracket 6 is welded by square tube as an integral support. The four sets of brake casters 11 at the bottom cooperate with the large load-bearing foot cups 12 with adjustable height to adapt to different work sites. The two sides and the top are welded with sheet metal and the through holes on the top ensure ventilation. The electric control box 9 is placed on the left side of the bracket. The handles 4 are set on the top of the four sides. The front opening and closing door 17 and the transparent acrylic back cover 1 on the back are convenient for operation and observation. The internal center is connected to the automatic opening and closing screening drum 13 through the angular contact bearing 16, the power end rotating shaft 2 and the support end rotating shaft 5. The tea separation channel 14 at the lower right and the flower separation channel 15 at the front left are conducive to the separation of finished products and waste materials. The top center funnel 8 is used for accurate feeding. The power transmission is driven by the servo motor 3 with a right-angle reducer through the coupling 10 to drive the automatic opening and closing screening drum 13 to flip.

[0053] The automatic opening and closing screening drum 13 has an exquisite structure, and the drum 28, drum cover 31, slide fixing seat 25, slide 24 and screen cover 32 work together. The drum cover 31 is welded with the hollow gear 18 and meshed with the motor gear 19. The servo motor 21 drives it to rotate left and right. The waist-shaped countersunk hole inside guides the slide 24 to move. The top slope entrance is convenient for feeding. The circular inlaid groove is equipped with an elastic retaining ring 22 to lock it and rotate synchronously with the drum 28 port. The slide fixing seat 25 is fixed to the drum 28, the slope outlet helps to discharge the material, and the waist-shaped countersunk hole assists the slide 24 to slide on another guide column. The five slides 24 are linked by double guide columns to realize the opening and closing of the drum port. The screen holes at the bottom of the side of the drum 28 and the screen holes of the screen cover 32 are misaligned to control the opening and closing. In addition, the material of the drum 28 is food-grade stainless steel, which not only ensures durability, but also ensures that the scented tea is not contaminated, extending the service life of the equipment while ensuring product quality. Its internal structural design has been precisely calculated, and the parameters such as the diameter and length of the drum 28 and the size and distribution density of the sieve holes have been optimized according to the process characteristics of scented tea making to achieve the best scenting effect.

[0054] The temperature monitoring is accurate. The temperature sensors are evenly distributed on the bottom and sides of the drum 28. The real-time data is transmitted to the touch screen 38, providing a basis for process control. The air nozzle 7 is equipped with a regulating valve to adjust the blowing size according to the working conditions to assist in cooling the camellia. These temperature sensors use high-precision thermistors, which can accurately sense temperature changes of 0.1°C, providing strong support for accurate control of the scenting temperature. The air outlet of the air nozzle 7 is designed as a special fan-shaped structure, which can make the blown airflow cover the inside of the drum more evenly and improve the cooling efficiency.

[0055] 2. Power and control

[0056] The power core is a servo motor 3 with a right-angle reducer, which stably outputs torque to drive the automatic opening and closing screening drum 13 to accurately flip, meeting the needs of different processes. The servo motor has a high-precision position control function, and its encoder resolution is as high as more than 10,000 pulses per revolution, which can accurately control the flip angle of the drum. Whether it is static scenting flowers, turning and mixing tea flowers, or separating tea and flowers, it can accurately position and ensure that each process link is executed in place.

[0057] The PLC-based automated electric control system is the "smart brain". The electric control box 9 integrates circuit breakers, leakage switches, etc. to ensure safety and stability. The panel start button 33, emergency stop button 34, power knob 35, touch screen 38, etc. realize human-computer interaction and conveniently control all aspects of the equipment. The PLC control system stores a variety of preset scented tea scenting process programs. Users only need to select the corresponding program on the touch screen 38 according to the actual situation of the scented tea variety, raw material ratio, etc., and the equipment can run automatically, which greatly reduces the difficulty of operation and improves production efficiency. At the same time, the system also has a fault self-diagnosis function. Once an electrical fault, motor overload, etc. occur, the fault code can be quickly displayed on the touch screen, which is convenient for maintenance personnel to quickly locate and solve the problem.

[0058] 2. Working Principle

[0059] 1. Preliminary preparation

[0060] The site is in place, turn the foot cup 12 to level the equipment according to the ground conditions, and lock the caster 11 to ensure stability without displacement. During the leveling process, a professional level can be used to assist in measurement, and the horizontal error of the equipment can be controlled within ±0.5mm, providing a stable foundation for the subsequent precise scenting process.

[0061] After the power is turned on, the power knob 35 is turned on, the touch screen 38 lights up, and the initial parameters of the equipment are quickly checked to lay the foundation for the subsequent process. At this time, the system will automatically perform a self-check to check the initial status of key components such as motors, sensors, and electric push rods. If an abnormality is found, an alarm will be immediately prompted on the touch screen to ensure that there are no hidden dangers before the equipment is started.

[0062] 2. Scenting process

[0063] Accurate feeding of raw materials into the barrel: fresh flowers and tea leaves are prepared according to the process formula, and the servo motor 21 is electronically controlled to open the barrel cover 31, and the raw materials are slowly fed into the funnel 8 to prevent clogging, and the cover is closed after feeding. When feeding the raw materials, the feeding speed of the funnel 8 can be controlled by the touch screen 38 according to the requirements of different scented teas. For example, for fresh flowers with delicate petals, a slower feeding speed is used to avoid the petals from breaking and affecting the quality of the scented tea.

[0064] Smart roller operation:

[0065] Static scenting: When the drum is in a vertical state (θ=90°), the internal materials are statically piled, and the floral fragrance slowly seeps into the tea leaves. During this period, the temperature sensor continuously monitors the temperature. During the blooming process of the flowers, the temperature of the camellia pile rises due to heat release caused by respiration and other reasons. The drum will first stir between 0 and 90°, stir evenly, and then place it horizontally at 0°. The drum port and the sieve holes will open automatically, and the air nozzle will then vent air to cool the temperature inside the drum and maintain a suitable scenting temperature to ensure that the floral fragrance is fully integrated into the tea leaves and the tea leaves are not damaged by high temperature.

[0066] Turning tea flowers: In the range of θ = 0 ~ 180°, the drum turns left and right to simulate manual turning and accelerate fusion. The turning speed of the drum can be adjusted according to the characteristics of the raw materials. For loose tea leaves, a slower turning speed is used to prevent excessive breakage of the tea leaves; for fresh flowers with greater viscosity, the turning speed is appropriately increased to ensure uniform mixing.

[0067] Spreading and opening the flowers: The drum is horizontal (θ=0°), the materials are spread, the air nozzle 7 blows air according to the temperature, and the air flow is cooled along the path of the air nozzle→drum port→drum screen, and the valve is adjusted to control the flow. The opening process can not only quickly reduce the temperature of the materials, but also loosen the accumulated materials, increase the oxygen contact area, promote the breathing of the flowers, and release more fragrance. At this time, the material temperature change curve can be viewed in real time through the touch screen 38, and the blowing parameters of the air nozzle 7 can be accurately adjusted according to the trend of the curve.

[0068] Separating tea and flowers: The screen cover 32 is driven by the electric push rod 29, which opens and closes with the roller screen grid, and the port slide cooperates with each other, and the θ flips up and down in a specific range for precise separation. During the separation process, the thrust of the electric push rod 29 can be dynamically adjusted according to the material accumulation. If the material is accumulated too much and the resistance is large, the system automatically increases the thrust to ensure that the screen cover 32 moves smoothly and achieves efficient separation.

[0069] Intelligent temperature control throughout the process: The temperature sensor monitors in real time. When the temperature is abnormal, it automatically triggers the drum to stir or the air nozzle to cool. The camellia is stirred and left to stand after it reaches room temperature. Multiple scenting can improve the efficiency and quality. Each temperature control adjustment will be recorded by the system to form a temperature control log, which is convenient for subsequent analysis of the temperature change law during the scenting process and optimization of process parameters.

[0070] 3. Final finishing touches

[0071] When the scenting reaches the standard, the equipment stops, the front door 17 is opened, and the tea leaves and flower residues are discharged and collected through the corresponding separation channels. The acrylic back cover 1 assists in observing the residues and ensures that the equipment is clean and ready for the next use. When cleaning the equipment, compressed air can be used to purge the hard-to-reach corners inside to ensure that there is no residual material, prevent bacteria from growing, and affect the quality of the next batch of scented tea.

[0072] 3. Usage

[0073] 1. Site installation and debugging: Choose a ventilated, flat, dry site to place the equipment, turn the foot cup 12, refer to the horizontal mark to level it, and lock the casters 11. When choosing a site, try to stay away from water sources, heat sources, and strong electromagnetic fields to avoid affecting the electronic components of the equipment and the quality of the scented tea. After the leveling is completed, a simple equipment stability test can be performed, such as gently pushing the equipment to observe whether there is displacement or shaking to ensure that the equipment is reliably installed.

[0074] 2. Inspection before startup: Open the electric control box cover 36, check the circuit breaker and other components, close the cover and turn the power knob 35 to light up the screen, check the temperature, motor and other initial parameters. During the inspection, you should also check whether the line connection is loose and whether the plug and socket are in good contact. If any problems are found, tighten or replace them in time to ensure safe startup.

[0075] 3. Raw material feeding operation: Prepare the materials according to the process, and the touch screen 38 controls the servo motor 21 to open the barrel cover 31, and slowly feed the materials through the funnel 8 to avoid blockage, and close the cover after feeding. Before feeding the raw materials, the raw materials can be preliminarily screened to remove impurities, dead leaves, etc. to improve the quality of the scented tea. At the same time, in order to ensure the accuracy of the amount of raw materials fed, an electronic scale can be used to weigh the flowers and tea leaves fed each time, and the data can be recorded to facilitate the subsequent optimization of the formula.

[0076] 4. Full control of the production process: The touch screen 38 sets the roller turning speed, time, temperature threshold, etc., and press the start button 33 to start the operation. During operation, the screen is monitored, the temperature is adjusted by the air nozzle 7, and the material blockage is handled by the emergency stop 34. During the monitoring process, the operator should record key parameters such as temperature, roller turning angle, electric push rod stroke, etc. at regular intervals to form a production record for tracing and analyzing product quality problems. If the equipment encounters abnormal vibration or abnormal sound, the emergency stop button 34 should be pressed immediately to find out the cause.

[0077] 5. Discharging and cleaning: When the scenting is in progress, the machine stops automatically or manually, the drum stops and the drum cover 31 is opened, and the tea leaves and flower residues are collected separately, and the internal residues are cleaned. When discharging, a special collection container can be used to hold the tea leaves and flower residues separately to avoid confusion. The collected tea leaves should be dried, packaged and processed in time, and the flower residues can be treated in an environmentally friendly way or reused. When cleaning the equipment, pay attention to protecting precision parts such as temperature sensors and electric push rods to avoid collision damage.

[0078] 6. Shutdown maintenance: Turn off the power (turn the power knob 35), clean the equipment of dust, regularly oil the rotating and transmission parts, check the wear of wearing parts and replace them. After shutting down, you can use a dust cover to cover the equipment to prevent dust accumulation. The regular maintenance cycle depends on the frequency of use of the equipment. Generally, when it is used frequently, a comprehensive maintenance is performed once a week; when it is used less frequently, maintenance is performed once a month. During the maintenance process, if it is found that the wear of wearing parts is close to the replacement standard, spare parts should be prepared in advance and replaced in time to ensure that the equipment is in good operating condition at all times.
