Description

Technical Field

[0001] The present invention relates to the technical field of tangerine peel storage, and particularly to a tangerine peel and tea storage system based on the regulation of biological enzyme activity. Background Art

[0002] The storage of tangerine peel and tea is an important link in production. During the storage process, the tangerine peel and tea are naturally aged. Aging refers to the process in which the tangerine peel and tea gradually change from fresh and bitter to mellow and fragrant through oxidation, enzymatic reactions, and microbial fermentation. The temperature and humidity during the aging process have a significant impact on the oxidation, enzymatic reactions, and microbial fermentation of the tangerine peel and tea.

[0003] In the related art, tangerine peel and tea are usually placed in plastic baskets or barrels and stacked in a warehouse. However, during the aging process, a small amount of water vapor is generated. When the water vapor condenses in the plastic basket or barrel, it will make the tangerine peel and tea damp, prone to blackening, mildew, and deterioration, affecting the color and taste. It is often necessary to take out the tangerine peel and tea for ventilation, consuming a large amount of manpower and material resources. Moreover, the stacked state makes the temperature and humidity distribution in the warehouse uneven, difficult to accurately control, and affects the activity of biological enzymes. Summary of the Invention

[0004] The present invention aims to solve one of the above technical problems. For this purpose, the present invention provides a tangerine peel and tea storage system and a regulation method based on the regulation of biological enzyme activity, which can effectively discharge water vapor and regulate the temperature and humidity in the warehouse, improve the activity of biological enzymes, and improve the quality of aging.

[0036] Referring to Figures 1 to 6 , the present invention proposes a storage system for tangerine peel and tea based on the regulation of bio-enzyme activity, aiming to precisely regulate the temperature and humidity in the warehouse through reasonable structural improvements, enhance the activity of bio-enzymes, and improve the quality of aging.

[0037] During the storage process of tangerine peel and tea, the uniformity and accuracy of temperature and humidity play an important role in the aging effect and final quality. In traditional storage methods, due to uneven distribution of temperature and humidity, problems such as blackening, mildew, and deterioration of tangerine peel and tea may occur, affecting the final product quality.

[0038] The storage system proposed by the present invention includes a warehouse 100 and a plurality of transportation components 200. The warehouse 100 serves as the carrier of the entire storage system, and its storage space is carefully divided into a central area 101 and four peripheral areas 102 surrounding the central area 101 (see Figure 1 ). This layout fully considers the convenience of air circulation, cargo storage, and the movement of transportation components 200 within the warehouse 100. The central area 101 is located at the core of the warehouse 100, facilitating efficient cargo exchange and air circulation with each peripheral area 102. The four peripheral areas 102 are evenly distributed around the central area 101, making full use of the space within the warehouse 100 and also providing a reasonable path for the subsequent movement of transportation components 200 between different areas.

[0039] The moving track 110 on the ground of the warehouse 100 is the basis for the logistics transportation of the entire warehousing system. The moving track 110 is not limited to steel rails, and can also be conveyor rollers, chains, or even virtual robot paths. Between the central area 101 and the peripheral areas 102, the moving tracks 110 are interconnected to form a complete transportation network, enabling the transportation component 200 to freely switch positions between the central area 101 and the four peripheral areas 102, realizing the rapid allocation and uniform distribution of goods.

[0040] The air conditioner equipped in the warehouse 100 is a key device for adjusting the temperature and humidity inside the warehouse 100. The air conditioner adopts advanced refrigeration and dehumidification technologies and can automatically adjust the operating parameters according to the actual temperature and humidity conditions inside the warehouse 100. The air outlets of the air conditioner are distributed on the top walls of both the central area 101 and the peripheral areas 102. The size and position of the air outlets are carefully designed to enable the cold air to be evenly blown to all areas inside the warehouse 100. The angle and wind speed of the air outlets can be adjusted to ensure that the cold air can fully cover the stored items in the warehouse 100, improving the cooling and dehumidification effects. The air inlets of the air conditioner are arranged at the lower parts of the side walls of the peripheral areas 102. The position and quantity of the air inlets are reasonably set according to the requirements of air circulation. The air inlets can suck the air inside the warehouse 100 back into the air conditioner in time for treatment, forming a complete air circulation system, making the air inside the warehouse 100 constantly flow, and avoiding the situation of excessively high or low local temperature and humidity, so as to ensure that the tangerine peel and tea leaves are aged in a suitable environment.

[0041] During the actual installation process, the selection of the air conditioner needs to be comprehensively considered according to factors such as the area and height of the warehouse 100 and the storage volume of tangerine peel and tea leaves. For example, for a warehouse 100 with an area of 1000 square meters and a height of 5 meters, if the storage volume is large, multiple high-power air conditioners may need to be installed to meet the requirements of temperature and humidity control inside the warehouse 100. At the same time, the position and quantity of the air outlets and air inlets also need to be accurately calculated and simulated tested to ensure that the air can evenly cover the entire space of the warehouse 100.

[0042] The transportation component 200 is the core component for the warehousing system to realize the automatic replacement and movement of goods. The transportation component 200 is located in the storage space of the warehouse 100 and can move flexibly along the moving track 110. The transportation component 200 mainly consists of a moving base 210, a multi-layer cage 220, and two groups of replacement mechanisms 230. Each part cooperates with each other to jointly complete the tasks of goods transportation and replacement.

[0043] The mobile base 210 is the basic support structure of the transportation component 200. Driving wheels are provided on its bottom surface, generally two sets of driving wheels are used, and the moving directions of the two sets of driving wheels are perpendicular to each other, enabling the transportation component 200 to move flexibly in both horizontal and vertical directions. One set of driving wheels can be lifted, and this design has great practicality. When the transportation component 200 needs to change the moving direction, the liftable driving wheels can be lifted to make the other set of driving wheels contact the moving track 110, thereby realizing the direction conversion.

[0044] The driving mode of the driving wheels usually adopts motor drive. The motor transmits power to the driving wheels through a transmission device, enabling the driving wheels to rotate. The transmission device can adopt chain drive. Chain drive has advantages such as high transmission efficiency and strong load-bearing capacity, and can meet the power requirements of the transportation component 200 during the moving process. The rotation speed and torque of the motor can be adjusted according to the load and moving speed of the transportation component 200 to ensure that the transportation component 200 can move stably and quickly. At the same time, in order to ensure good contact and transmission effect between the driving wheels and the moving track 110, the surface of the driving wheels is made of special rubber material, which has good friction and wear resistance.

[0045] The multi-layer cage 220 is fixed on the top surface of the mobile base 210. The multi-layer cage 220 is provided with a plurality of storage cavities distributed vertically. Each storage cavity can accommodate a loading bucket 300. The loading bucket 300 is made of food-grade plastic or metal, and the bucket wall is provided with ventilation holes to meet the good ventilation requirements. The ventilation can ensure that tangerine peel and tea leaves can exchange appropriately with the outside air during storage, which is beneficial to the regulation of the activity of biological enzymes. The size and shape of the storage cavity are designed according to the size of the loading bucket 300 to ensure that the loading bucket 300 can be stably placed in the storage cavity.

[0046] It can be understood that the multi-layer cage 220 can be two layers, three layers or even more layers, designed according to the height of the warehouse 100. Here, two layers are taken as an example for illustration. Refer to Figure 1 and Figure 2 , in some embodiments, the specific structure of the multi-layer cage 220 includes three bottom plates 221 and a plurality of support rods 222. The bottom plates 221 are circular and are provided with a plurality of ventilation holes. The diameter and distribution density of the ventilation holes are carefully designed to ensure the air circulation. The plurality of support rods 222 arranged between the two bottom plates 221 are distributed in a semi-circular shape to form the side wall and the inlet and outlet of the loading bucket 300. This enables the loading bucket 300 to be conveniently placed into and taken out of the storage cavity. The material of the support rods 222 is selected as stainless steel. Stainless steel has good strength and corrosion resistance, which can ensure the structural stability and service life of the multi-layer cage 220. At the same time, the surface of the support rods 222 is smooth-treated to avoid scratching the loading bucket 300 during the process of putting the loading bucket 300 into and taking it out.

[0047] The swapping mechanism 230 is one of the key innovations of this warehousing system and can achieve the swapping of the loading buckets 300 in each storage cavity. Two groups of swapping mechanisms 230 are arranged on the opposite sides of the multi-layer cage 220, and each group of swapping mechanisms 230 includes a vertically arranged conveyor belt 231 and a rotating device.

[0048] The conveyor belt 231 spans multiple storage cavities and functions to drive the loading bucket 300 to move vertically. The conveyor belt 231 can adopt various forms such as a belt or a chain. For example, the conveyor belt 231 is a belt, and the inner wall of the inner cylinder 232 is provided with a fixed plane, and the fixed plane and the belt are fixed by high-strength glue or bolts, which can ensure a firm connection between the belt and the inner cylinder 232 and prevent loosening or falling off during the conveying process. An active pulley and a passive pulley are respectively arranged at the upper and lower ends of the multi-layer cage 220, and the belt is wound around the active pulley and the passive pulley. The material of the belt is selected as wear-resistant and corrosion-resistant rubber material, which can adapt to the complex environment in the warehouse 100.

[0049] Another example is that the conveyor belt 231 is a chain. An active sprocket and a passive sprocket are respectively arranged at the upper and lower ends of the multi-layer cage 220, and the chain is wound around the active sprocket and the passive sprocket. The inner wall of the inner cylinder 232 is provided with a lock, and the lock adopts a special structural design, which can firmly lock the chain. The installation and disassembly of the lock are convenient and fast, which is convenient for maintaining and replacing the conveyor belt 231 when needed. The chain drive has the advantages of high transmission accuracy and strong bearing capacity, which can meet the accuracy and stability requirements of the loading bucket 300 during the conveying process.

[0050] Refer to Figure 5 and Figure 6, the rotating device includes an inner cylinder 232 and an outer cylinder 233. The inner cylinder 232 is fixed to the conveyor belt 231, and the outer cylinder 233 is sleeved on the inner cylinder 232 and can rotate. The outer cylinder 233 is connected to a driving member 234 to achieve rotation. The driving member 234 can be selected from a motor, a speed reducer, and a driving gear 235. The motor is installed on the outer wall of the outer cylinder 233. The motor uses a high-precision and high-efficiency servo motor, which can accurately control the rotation speed and angle of the outer cylinder 233. The speed reducer is connected to the rotating shaft of the motor. The function of the speed reducer is to reduce the rotation speed of the motor and increase the torque to meet the power requirements for the rotation of the outer cylinder 233. The driving gear 235 is connected to the output shaft of the speed reducer, and a toothed ring 236 meshing with the driving gear 235 is provided on the outer wall of the lower end of the inner cylinder 232. When the motor is started, the rotation speed of the motor is reduced and the torque is increased through the speed reducer, and then the driving gear 235 rotates. Limited by the toothed ring 236 on the inner cylinder 232, the outer cylinder 233 rotates around the inner cylinder 232. The rotation angle of the outer cylinder 233 can be accurately controlled according to actual needs. For example, the outer cylinder 233 can be rotated 90 degrees, 180 degrees, etc. to realize the loading bucket 300 entering and exiting the storage cavity. In addition, the driving member 234 can be selected from other power devices such as a rotary cylinder.

[0051] The outer cylinder 233 is provided with a support arm 237 to connect the loading bucket 300. The shape and length of the support arm 237 can avoid the support rod 222 and can stably support and carry the loading bucket 300 at the same time. The material of the support arm 237 can be selected as aluminum alloy. Aluminum alloy has the characteristics of light weight and high strength, which can reduce the overall weight of the replacement mechanism 230 and improve the operation efficiency of the replacement mechanism 230.

[0052] Refer to Figure 4 , a positioning member 238 is provided on the outer wall of the multi-layer cage 220, and a telescopic bolt is provided on the positioning member 238. The function of the positioning member 238 is to provide accurate positioning for the inner cylinder 232 when the rotating device drives the loading bucket 300 to enter and exit the storage cavity. The telescopic bolt is driven pneumatically or electrically and can quickly extend or retract when needed. When the replacement mechanism 230 moves to the set height, the telescopic bolt extends and inserts into the pin hole on the inner cylinder 232, so that the inner cylinder 232 and the multi-layer cage 220 are relatively fixed, which can ensure the accuracy and stability of the replacement. For example, when it is necessary to take out the loading bucket 300 in a certain storage cavity, the replacement mechanism 230 moves to the corresponding position, the telescopic bolt of the positioning member 238 extends and inserts into the pin hole of the inner cylinder 232, so that the replacement mechanism 230 and the multi-layer cage 220 are fixed, and then the replacement mechanism 230 can accurately take out the loading bucket 300. In addition, the positioning member 238 can also use structures such as magnetic attraction and locking to limit the rotating device as long as the use requirements are met.

[0053] In use, when it is necessary to replace the loading bucket 300 of a certain transportation component 200, the telescopic bolt of the positioning member 238 cooperates with the pin hole of the inner cylinder 232 to fix the replacement mechanism 230 to the multi-layer cage 220. The driving member 234 is activated to rotate the outer cylinder 233, driving the support arm 237 and the loading bucket 300 to rotate together, and the loading bucket 300 leaves the storage cavity. Then the telescopic bolt of the positioning member 238 retracts, and the conveyor belt 231 is activated to bring the loading bucket 300 to the corresponding storage cavity. The two replacement mechanisms 230 operate synchronously to achieve replacement.

[0054] The replacement mechanism 230 operates according to the above steps. First, the loading bucket 300 in the storage cavity is taken out, and then the loading bucket 300 is transported to another storage cavity or flipped as needed. This can not only achieve the replacement of the loading bucket 300, but also help to flip the tangerine peel and tea leaves in the loading bucket 300, enabling them to come into contact with the cold air more evenly, avoiding some tangerine peel and tea leaves from not being able to contact the cold air for a long time, and thus improving the uniformity of temperature and humidity distribution.

[0055] In some embodiments, a first temperature and humidity sensor is provided on the outer peripheral wall of the warehouse 100, second temperature and humidity sensors are provided on both the bottom wall and the top wall of the peripheral area 102, and third temperature and humidity sensors are provided on both the bottom wall and the top wall of the central area 101. The first temperature and humidity sensor, the second temperature and humidity sensor, the third temperature and humidity sensor, the air conditioner, and the transportation component 200 are all electrically connected to the controller.

[0056] The first temperature and humidity sensor uses a high-precision digital temperature and humidity sensor, with a measurement range of temperature -20°C - 60°C, humidity 0% - 100%RH, and a measurement accuracy of temperature ±0.5°C, humidity ±1%RH. It is used to monitor the temperature and humidity of the external environment of the warehouse 100 in real time. Since the outer peripheral wall of the warehouse 100 may be affected by the external environment, such as sunlight irradiation and external air flow, the temperature and humidity changes at this position are relatively large. By setting the first temperature and humidity sensor, the degree of influence of the external environment on the temperature and humidity inside the warehouse 100 can be understood in a timely manner, providing a reference basis for the regulation of the air conditioner.

[0057] The second temperature and humidity sensor also uses a high-precision digital temperature and humidity sensor, and its performance parameters are similar to those of the first temperature and humidity sensor. The second temperature and humidity sensors are respectively provided on the bottom wall and the top wall of the peripheral area 102. Its function is to monitor the temperature and humidity at different heights inside the peripheral area 102. Since the cold air blows downward from the air outlet on the top wall, the temperature and humidity may change during the descent. Therefore, by setting temperature and humidity sensors on the bottom wall and the top wall, the temperature and humidity distribution inside the peripheral area 102 can be comprehensively understood.

[0058] The third temperature and humidity sensor also uses the same high-precision digital temperature and humidity sensor, which is installed on the bottom wall and the top wall of the central area 101. The third temperature and humidity sensor is used to monitor the temperature and humidity in the central area 101. The central area 101 is an important area in the warehouse 100, and its temperature and humidity conditions have an important impact on the storage environment of the entire warehouse 100. By setting the third temperature and humidity sensor, the temperature and humidity changes in the central area 101 can be grasped in a timely manner, so that the air conditioner can be adjusted in a timely manner.

[0059] The controller uses a programmable logic controller. For example, PLC has the advantages of high reliability, strong anti-interference ability, and flexible programming. The PLC is connected to each temperature and humidity sensor, air conditioner, and transportation component through data lines, receives the data fed back by the temperature and humidity sensors in real time, and controls the air conditioner and transportation component according to the preset program.

[0060] In order to facilitate the operator to monitor and manage the storage system, a human-machine interface (HMI) is also provided. The HMI uses a touch screen display and is installed in the control room of the warehouse. The operator can view information such as the temperature and humidity data in the warehouse and the operating status of the equipment in real time through the HMI, and perform corresponding operations and settings.

[0061] A second aspect of the present invention proposes a regulation method, which is applied to the above storage system and includes the following steps.

[0062] S100. Data acquisition step

[0063] First, the temperature and humidity data outside the warehouse are obtained through the first temperature and humidity sensor, which can reflect the changes in the external environment of the warehouse and provide a reference basis for subsequent regulation. The temperature and humidity data at the top and bottom of the surrounding area are obtained by using the second temperature and humidity sensor, and the temperature and humidity data at the top and bottom of the central area are obtained through the third temperature and humidity sensor. Through multi-region and multi-point data acquisition, the temperature and humidity distribution in the warehouse can be comprehensively understood, providing accurate data support for subsequent calculations and judgments.

[0064] S200. Data processing and calculation step

[0065] After the controller receives the data from each sensor, it will perform a series of calculations and analyses. First, calculate the temperature difference C1 between inside and outside the warehouse, where the temperature inside the warehouse is the average value of the temperature values of each sensor; the temperature difference C1 can intuitively reflect the influence degree of the external environment of the warehouse on the internal temperature of the warehouse. Secondly, calculate the maximum change values A1 of the temperature and humidity at the top and bottom of the surrounding area within half an hour, and the maximum change values A2 of the temperature and humidity at the top and bottom of the central area within half an hour respectively. It can reflect the fluctuation of temperature and humidity in different areas inside the warehouse and provide a basis for subsequent regulation decisions.

[0066] S300, Regulation Operation

[0067] When the controller determines that the temperature difference C1 is greater than the set value, the external environment of the warehouse will have a greater impact on the internal temperature of the warehouse. At this time, the controller will send a start command to the air conditioner. After the air conditioner starts, it will supply cold air to the surrounding area and the central area to reduce the temperature in the warehouse, thereby maintaining the stability of the temperature in the warehouse.

[0068] When the controller determines that the maximum value A1 of the temperature and humidity changes at the top and bottom of the surrounding area is greater than the set value, the temperature and humidity in the surrounding area fluctuate greatly, which may affect the quality of the tangerine peel tea stored in this area. At this time, the controller will control the transportation component in the surrounding area to start. The transportation component exchanges the loading buckets in multiple storage chambers through two sets of exchange mechanisms, so that the loading buckets originally in different temperature and humidity environments are exchanged in position, thereby helping to balance the temperature and humidity distribution in the surrounding area and reducing the impact of temperature and humidity fluctuations on the tangerine peel tea.

[0069] Similarly, when the controller determines that the maximum value A2 of the temperature and humidity changes at the top and bottom of the central area is greater than the set value, it will control the transportation component in the central area to start, and exchange the loading buckets in the storage chamber through the exchange mechanism to balance the temperature and humidity distribution in the central area.

[0070] The temperature and humidity in the warehouse adopt the PID control method, and the target temperature is set to T set , then the temperature deviation is ΔT = T set - T0, where T0 is the temperature in the warehouse, which is the average value calculated from the temperature values of each sensor in the warehouse; the temperature regulation equation is: where K p , K i , K d are the measured proportional, integral and differential coefficients. At the same time, the difference ΔT1 between A1 and the set value, and the difference ΔT2 between A2 and the set value are set. μt needs to add a compensation value, and the compensation values are 1% * ΔT1 and 1% * ΔT2.

[0071] It can be understood that the humidity regulation equation is basically the same as that of the temperature, and the above can be referred to.

[0072] Furthermore, through more in-depth analysis of temperature and humidity data, more precise control of the transportation component is achieved, further improving the effect of warehouse temperature and humidity regulation.

[0073] The controller calculates the difference B1 between the maximum value and the minimum value of A1 within 12 hours, and the difference B2 between the maximum value and the minimum value of A2 within 12 hours. These two differences can reflect the overall situation of temperature and humidity fluctuations in the surrounding area and the central area over a long period of time, providing a more comprehensive basis for subsequent regulation decisions.

[0074] When the controller determines that B1 is less than or equal to B2, it indicates that the temperature and humidity fluctuations in the peripheral area are smaller than those in the central area. The transportation components in the peripheral area and the central area maintain their positions unchanged to maintain the current relatively stable temperature and humidity distribution state.

[0075] When the controller determines that B1 is greater than B2, it indicates that the temperature and humidity fluctuations in the peripheral area are larger than those in the central area, while the temperature and humidity fluctuations in the central area are relatively smaller. At this time, the controller will control the transportation components in the peripheral area and the central area to start, and exchange at least some of the transportation components in the peripheral area with the transportation components in the central area. Through this exchange, the loading buckets originally in the area with large temperature and humidity fluctuations can be moved to the area with small temperature and humidity fluctuations, thereby helping to balance the temperature and humidity distribution in the warehouse and improving the storage quality of tangerine peel tea.

[0076] The transportation components move along the moving track, and through the instructions sent by the controller, the exchange of transportation components between different areas is achieved. At the same time, in order to ensure the smooth progress of the exchange process, it is necessary to precisely control the moving speed, position accuracy, etc. of the transportation components to avoid damaging the loading buckets in the storage cavity.

[0077] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art to which the present invention pertains, various changes can be made without departing from the gist of the present invention.
