Abstract
Description
Technical Field
[0001] This utility model relates to the field of rice bran processing technology, and in particular to a refrigeration device for processing high-value-added rice bran products. Background Technology
[0002] In the cold storage of agricultural products such as rice bran, traditional storage equipment generally suffers from drawbacks such as inefficient temperature and humidity control and low space utilization. Existing technologies mostly employ a single refrigeration mode. While they cool the food using compressors, they lack dynamic humidity control mechanisms. When ambient humidity is too high, they can only rely on low temperatures to delay condensation, leading to rice bran easily absorbing moisture and clumping. Conversely, when humidity is too low, they cannot actively humidify, causing accelerated fat oxidation. Furthermore, the rigid storage structure is a significant problem; the shelf spacing is not adjustable, making it difficult to accommodate different sizes of rice bran packaging (5-25kg / bag), resulting in a space waste rate exceeding 30%.
[0003] The sealing performance of existing equipment also has defects. For example, the doors are mostly sealed with ordinary rubber strips, which are prone to aging and deformation after frequent opening and closing, resulting in a cold air leakage rate as high as 15%-20%. This forces the compressor to start and stop frequently, which not only increases energy consumption but also significantly shortens the equipment's lifespan. More seriously, traditional air circulation systems are only equipped with a primary filter, and dust easily accumulates on the evaporator surface, requiring monthly shutdowns for cleaning, which seriously affects continuous operation.
[0004] In terms of humidity regulation, the mainstream solutions are limited to one-way dehumidification. Although they can reduce humidity, they cannot reverse the humidification in the dry season, which causes the moisture content of rice bran to fluctuate by more than ±5%, thus damaging its microecological stability.
[0005] Therefore, there is an urgent need to develop a refrigeration equipment with bidirectional humidity regulation, modular storage architecture, and high-efficiency sealing to solve the systemic defects of traditional technologies, such as inaccurate temperature and humidity control, poor spatial adaptability, and excessive energy consumption, thereby extending the shelf life of rice bran products and reducing operating costs. Utility Model Content
[0006] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a refrigeration device for processing high-value-added rice bran products, solving the technical problem of bidirectional humidity regulation.
[0007] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: A refrigeration device for processing high-value-added rice bran products, comprising: The storage silo is a structural compartment with a central partition dividing it into two parts: a refrigeration compartment and an equipment compartment. Inside the refrigeration compartment, brackets are bolted to both sides, and several sets of support plates are attached to these brackets. Rice bran processing products requiring refrigeration are placed on top of these support plates. The bracket has a sliding groove in the middle, and a protruding positioning block is provided at the corresponding support plate position. The horizontal position of the support plate is limited by sliding the positioning block of the support plate up and down in the sliding groove. In addition, several sets of limiting blocks are provided on the outside of the bracket. The limiting blocks are used to support the support plate, and the position of the limiting blocks can be adjusted according to the usage requirements.
[0008] Preferably, a temperature control mechanism is provided at the back of the refrigeration chamber. The temperature control mechanism includes a temperature control compartment, which is a hollow square frame. A purification channel is provided in the middle of the temperature control compartment. The purification channel is equipped with filter blocks and dehumidifier blocks, which can filter and remove dust and purify and dehumidify the incoming gas, respectively.
[0009] Preferably, an air inlet pipe and an exhaust pipe are respectively provided on both sides below the temperature control chamber, which are used to control the intake and exhaust of gas exchange with the temperature control chamber. The air inlet pipe and the exhaust pipe pass through the side wall of the storage hopper and exchange air with the refrigeration chamber.
[0010] Preferably, the upper outer side of the air inlet pipe is connected to one end of the filter block, and the other end of the filter block is equipped with an air pump. The air pump draws in the air through the negative pressure in the air inlet pipe. The right side of the air pump is connected to the dehumidification block, which dehumidifies the passing air, thus better controlling the humidity of the refrigeration chamber. The end of the dehumidification block is connected to the exhaust pipe, which introduces the dust-removed and dehumidified air into the refrigeration chamber.
[0011] Preferably, the temperature control chamber is equipped with insulation cotton on the outside to prevent the gas from being pressurized during circulation, which would affect the efficiency of the refrigeration equipment. In addition, there is an optimal range for humidity control, so it is necessary to control whether to use dehumidifier blocks for dehumidification according to the usage requirements. A connecting pipe is set between the air pump and the dehumidifier block. A hygrometer is set inside the storage hopper to detect the temperature and humidity of the freezer chamber. A direct connecting pipe is set between the air pump and the exhaust pipe. The direct connecting pipe bypasses the dehumidifier block and connects directly to the exhaust pipe. A humidifying plate is set in the middle of the direct connecting pipe. Solenoid valves are set in the direct connecting pipe and the connecting pipe to control the opening and closing of the channels. They are divided into dehumidification lines and humidification lines. The solenoid valves can be adjusted according to the measurement structure of the hygrometer.
[0012] Preferably, a cover is rotatably installed on the outside of the freezer compartment. The cover is a door panel with a hinged rotation and magnetic attraction control. A sealing strip is provided on the outside of the cover. The sealing strip is a rubber sealing ring, which has better sealing performance.
[0013] Preferably, the equipment compartment includes a compressor, which is connected to the freezer compartment via a refrigeration device passing through a central partition to refrigerate it. A central screen is installed outside the equipment compartment to protect the compressor and perform simple filtration and dust removal.
[0014] (III) Beneficial Effects 1. Precise temperature and humidity control: The temperature control mechanism monitors the humidity data of the freezer compartment in real time through a hygrometer. When the detected value is higher than the set threshold, the solenoid valve of the connecting pipe opens, and the air pump presses the humid air through the filter block to remove dust and into the dehumidification block. The treated dry air is then returned to the compartment through the exhaust pipe. If the detected humidity is insufficient, the solenoid valve of the direct connecting pipe opens, and the built-in ultrasonic humidification plate atomizes pure water, which, together with the air pump, directly injects humidified air.
[0015] 2. Modular storage adaptation: The T-shaped groove of the bracket and the raised positioning block at the bottom of the support plate form a sliding pair. When the single plate bears a load of 50kg, it can still be pushed and pulled with one hand for adjustment. The welding group of each bracket can rotate the limiting block and is fixed to the preset screw hole by the internal hex bolt.
[0016] 3. Long-term operation guarantee: the filter block adopts a PP melt-blown + activated carbon composite structure; the dehumidification block is a replaceable honeycomb ceramic carrier; and the screen in the middle of the equipment compartment is made of stainless steel woven mesh.

[0020] This application provides a refrigeration device for processing high-value-added rice bran products, solving the problem of bidirectional humidity regulation in the prior art. The temperature control mechanism monitors the humidity data of the freezer compartment in real time through a hygrometer. When the detected value is higher than the set threshold, the solenoid valve of the connecting pipe opens, and the air pump presses the humid air through the filter block to remove dust and into the dehumidification block. The treated dry air is then returned to the compartment through the exhaust pipe. If the detected humidity is insufficient, the solenoid valve of the direct connecting pipe opens, and the built-in ultrasonic humidification plate atomizes pure water, which, together with the air pump, directly injects humidified air.
[0021] Example 1 The technical solution in this application embodiment is to solve the above-mentioned modular storage architecture problem, and the overall idea is as follows: like Figure 1 As shown, in view of the problems existing in the prior art, this utility model provides a refrigeration device for processing high value-added rice bran products, including... The storage silo 1 is a structural compartment. A central partition 2 is provided in the middle of the storage silo 1, which divides the storage silo 1 into two parts: a freezing compartment and an equipment compartment. Inside the freezing compartment, brackets 7 are fixed to both sides by bolts. Several sets of support plates 6 are clamped and installed on the brackets 7. Rice bran processing products that need to be refrigerated are placed on the support plates 6. like Figure 2 As shown, a sliding groove is provided in the middle of the bracket 7, and a protruding positioning block is provided at the corresponding position of the support plate 6. The horizontal position of the support plate 6 is limited by sliding the positioning block of the support plate 6 up and down in the sliding groove. In addition, several sets of limiting blocks 9 are provided on the outside of the bracket 7. The limiting blocks 9 are used to support the support plate 6, and the position of the limiting blocks 9 can be adjusted according to the requirements of use.
[0022] The T-shaped groove of the bracket 7 and the raised positioning block at the bottom of the support plate 6 form a sliding pair. When the single plate bears a weight of 50kg, it can still be pushed and pulled with one hand for adjustment. Each side of the bracket is welded with 6 sets of rotatable limit blocks 9, which are fixed to the preset screw holes by internal hex bolts, so that the height of the shelf can be freely positioned between 300-1200mm with a gradient of 50mm.
[0023] like Figure 3 As shown, a temperature control mechanism 8 is installed at the back of the refrigeration chamber. The temperature control mechanism 8 includes a temperature control chamber 81, which is a hollow rectangular frame. A purification channel is provided in the middle of the temperature control chamber 81. A filter block 85 and a dehumidifier block 87 are installed in the purification channel, which can filter and remove dust and purify and dehumidify the incoming gas, respectively. The filter block 85 adopts a PP melt-blown + activated carbon composite structure, and the dehumidifier block 87 is a replaceable honeycomb ceramic carrier. An air inlet pipe 82 and an exhaust pipe 83 are respectively installed on both sides of the lower part of the temperature control chamber 81. These are used to control the intake and exhaust of gas exchange with the temperature control chamber 81. The air inlet pipe 82 and the exhaust pipe 83 pass through the side wall of the storage hopper 1 to exchange air with the refrigeration chamber. The upper outer side of the air inlet pipe 82 is connected to one end of a filter block 85. An air pump 86 is installed at the other end of the filter block 85. The air pump 86 draws in air through the negative pressure in the air inlet pipe 82. The right side of the air pump 86 is connected to a dehumidification block 87, which dehumidifies the passing air, thus better controlling the humidity of the refrigeration chamber. The end of the dehumidification block 87 is connected to the exhaust pipe 83, which guides the dehumidified and dust-removed air into the refrigeration chamber. The temperature control chamber 81 is equipped with insulation cotton on the outside to prevent the gas from being pressurized during circulation, which would affect the efficiency of the refrigeration equipment. In addition, there is an optimal range for humidity control, so it is necessary to control whether to use the dehumidification block 87 for dehumidification according to the usage requirements. A connecting pipe 89 is provided between the air pump 86 and the dehumidification block 87. A hygrometer 84 is provided inside the storage bin 1 to detect the temperature and humidity of the freezer chamber. A direct connecting pipe 88 is provided between the air pump 86 and the exhaust pipe 83. The direct connecting pipe 88 bypasses the dehumidification block 87 and connects directly to the exhaust pipe 83. A humidifying plate is provided in the middle of the direct connecting pipe 88. A solenoid valve is provided in the direct connecting pipe 88 and the connecting pipe 89 to control the opening and closing of the channel. It is divided into a dehumidification line and a humidification line. The solenoid valve can be adjusted according to the measurement structure of the hygrometer 84.
[0024] The temperature control mechanism monitors the humidity data of the freezer compartment in real time through the hygrometer 84. When the detected value is higher than the set threshold, the solenoid valve of the connecting pipe 89 opens, and the air pump 86 pressurizes the humid air into the dehumidification block 87 (silica gel / molecular sieve composite layer) after the filter block 85 removes dust. The dehumidification efficiency reaches 95%, and the treated dry air is returned to the compartment through the exhaust pipe 83. If the detected humidity is insufficient, the solenoid valve of the direct connecting pipe 88 opens, and the built-in ultrasonic humidification plate atomizes pure water, which, together with the air pump, directly injects humidified air.
[0025] A cover plate 5 is rotatably installed on the outside of the freezer compartment. The cover plate 5 is a door panel with a hinged rotation and magnetic suction opening and closing control. A sealing strip 10 is provided on the outside of the cover plate 5. The sealing strip 10 is a rubber sealing ring, which has better sealing performance.
[0026] The equipment compartment includes a compressor 4, which is connected to the freezer compartment via a refrigeration device passing through the central partition 2 to refrigerate it. A central screen 3 is installed outside the equipment compartment. The central screen 3 of the equipment compartment is made of 304 stainless steel woven mesh, which protects the compressor 4 and provides simple filtration and dust removal.
[0027] Technical effects: Dual-mode humidity control: The innovative dehumidification / humidification parallel air duct switches modes within 5 seconds by triggering the solenoid valve through a humidity threshold.
[0028] Quick-install shelf system: The raised positioning block and sliding groove realize "one push and lock", and a single person can complete the disassembly and reassembly of the shelf within 30 seconds.
[0029] Dynamic airflow management: The negative pressure suction of the air pump 86, combined with the purification channel, forms a directional circulating airflow, avoiding local condensation and achieving a temperature uniformity of ±0.5℃.
[0030] This design significantly improves the adaptability, reliability, and economy of rice bran refrigeration equipment through modular structure, intelligent control, and energy efficiency optimization.
[0031] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
