Description

Technical Field

[0001] The utility model relates to the technical field of grain storage, in particular to a grain and bean storage barrel. Background Art

[0002] Rice, wheat, corn, soybeans, mung beans, red beans, peas and other grains and legumes are an important part of people's daily diet, providing humans with rich nutrients such as carbohydrates, protein, dietary fiber, vitamins and minerals.

[0003] At present, the storage method of grain and bean foods is relatively rough. They are usually placed in a cool corner of the kitchen after being opened from the original packaging. The kitchen has high humidity, high temperature, and large temperature changes. The high temperature and humid environment will seriously affect the quality of grain and bean food materials.

[0004] Some people store them in sealed barrels, but simply sealing them cannot prevent grains and beans from spoiling. High temperatures will accelerate the respiration of grains and cereals, causing their quality to decline, affecting their consumption or even rendering them inedible. For example, Job's tears are prone to a rancid smell in a high-temperature environment, and if the moisture content of grains and beans is high in a sealed environment, it will promote the growth of anaerobic bacteria. For example, soybeans are prone to moisture absorption, fever, mold, and oil-soaked redness during storage. Secondly, grains are living organisms that need to respire. A sealed environment will also affect the respiration of grains, causing the internal structure of the grains to gradually loosen, enzyme activity to decrease, and grains to age. For example, long-term storage of rice in a sealed environment will lead to hardening of the tissue, weakening of flexibility, gluten formation, and shrinkage of the grains, resulting in a decline in steaming quality, reduced viscosity, broken rice, disappearance of fragrance, and a sour taste. Furthermore, in a sealed environment, if the external environment changes significantly, moisture may condense inside the sealed environment and be unable to evaporate, increasing the risk of moisture and mildew in grain and bean ingredients.

[0005] Chinese Patent No.: ZL202121695496.0 discloses an intelligent grain storage and mildew prevention device, including a mildew prevention cover at the top of a storage box, air inlet windows on the four side walls of the mildew prevention cover, an electric fan installed in the middle, an air outlet at the bottom, a ventilation tube rotatably connected to the bottom of the air outlet, a plurality of air outlet holes and a plurality of stirring blades fixedly connected to the outer wall of the ventilation tube, a driving frame slidably connected to the inner and outer walls of the driving frame and a driving rack and a side rack respectively, a gear ring fixedly connected to the outer wall of the ventilation tube, the side rack and the gear ring are meshed, the driving frame is driven by a reversing motor, a discharge port is provided at the bottom of the storage box, and a closing cover is rotatably connected to the bottom, and the closing cover is located at The bottom of the discharge port is sealed. The intelligent grain storage and mildew prevention device uses ventilation, heating and drying to avoid moisture and mildew, prolongs the storage time of grains, and realizes automatic discharge. However, the device is not conducive to the long-term storage of grains. First, the high temperature generated by the electric fan will accelerate the respiration of grains and affect the quality; second, when the ventilation tube and the stirring blades rotate, they will constantly collide and rub with the grains stored in the storage box, which can easily cause the grains to break; third, the "return of the south wind" weather phenomenon in southern my country in spring, the air humidity is close to saturation, and the humid air is heated by the electric fan, so that the humid air is heated into hot and humid air and then overflows through the air outlet on the ventilation tube to the grains at all levels, which will accelerate the mildew of the grains.

[0008] The following beneficial effects can be achieved by using the intelligent grain and bean storage barrel provided by the utility model:

[0009] (1) The refrigeration system in the refrigeration and air supply area reduces the temperature and humidity of the grains and beans stored in the loading area, so that the grains and beans are in a low temperature and dry environment, and the moisture content of the grains and beans is reduced to keep low, thereby preventing internal heat and moisture accumulation, moisture absorption, condensation and mildew; the temperature is lowered to slow down the physiological metabolism of grains and beans, inhibit the growth and reproduction of microorganisms and pests, and thus extend the storage time of grains and beans.

[0010] (2) The loading area and the unloading area are separated by an air supply inclined plate, which makes it easier for grains or beans to slide down and be taken out under gravity. At the same time, it facilitates air circulation, speeds up the discharge of hot and humid air between grains and beans, and effectively prevents insects and rats from entering from the outside and causing pollution. At the same time, by taking grains and beans in and out from the top, no old grains and beans are left.

[0011] (3) The CCD camera can automatically identify the type of stored grains or beans. Combined with the controller, humidity sensor, temperature sensor and refrigeration system, it can control the optimal storage environment according to the identified type of grains or beans, thereby maximizing the freshness and nutritional value of the stored grains and beans while extending the storage period.

[0012] (4) The distance sensor senses the distance between the top of the barrel and the top of the stored grains and beans, and determines the remaining amount of stored grains or beans, thereby realizing an instant reminder function when the storage amount is insufficient, so as to facilitate instant replenishment.

[0014] Two inclined air supply ramps allow the grains and beans stored in the loading area to automatically fall under the action of gravity, and the discharge is smooth, making it easy to take out the grains and beans as needed, and preventing some grains and beans from being blocked from falling due to dead corners, resulting in overstorage; the air supply ramps with ventilation mesh holes facilitate internal gas flow, preventing moisture and heat accumulation inside the grains and beans.

[0015] Preferably, the unloading area includes a storage pipe, a unloading hopper and a unloading pipe, the bottoms of the two air supply inclined plates are fixedly connected to the top of the storage pipe, and the top of the storage pipe is connected to the receiving area; a rotating baffle and a first motor are provided in the storage pipe, the cross-section of the rotating baffle is radial, and the rotating baffle is connected to the power output end shaft of the first motor.

[0016] The grains and beans stored on the air supply inclined plate first slide into the storage pipe under the action of gravity. The falling speed is controlled by rotating the baffle to prevent the grains and beans from directly connecting with the outside world, and to prevent insects and rodents from entering the loading area from the outside.

[0017] Preferably, an inclined baffle is provided above the first motor, the top of the baffle is fixedly connected to the inner wall of the barrel body, and the two ends of the baffle are respectively fixedly connected to the two air supply inclined plates.

[0018] The baffle can eliminate the dead corner above the first motor where grain and beans cannot fall.

[0019] Preferably, the bottom of the storage pipe is connected to the top of the lower hopper, and the bottom of the lower hopper is provided with a lower pipe perpendicular to the storage pipe, and the bottom of the lower hopper is connected to the top of one end of the lower pipe.

[0020] The grains and beans that enter the storage pipe fall downward into the lower hopper at intervals under the control of the rotating baffle. After being concentrated in the lower hopper, they continue to fall downward into the lower pipe, which is convenient for accommodating grains or beans of different particle sizes and preventing large grains and beans from piling up and causing blockage.

[0021] Preferably, a spiral auger is provided in the discharge pipe, and a second motor is fixed to the end of the discharge pipe away from the discharge hopper, and the spiral auger is connected to the power output end shaft of the second motor; an opening is provided at the bottom of the discharge pipe, and the discharge pipe is connected to the bottom of the discharge area through the opening; a pull-out receiving box is provided at the bottom of the discharge area, and a handle is provided on the outer wall of the receiving box.

[0022] The grains and beans that fall into the discharge pipe are pushed to the opening at the other end by a spiral auger, and finally fall downward from the opening into a removable receiving box, so that the falling speed is uniform and there is no blockage when taking out the grains and beans, and at the same time, waste of grains and beans caused by leakage during transportation or shaking is avoided.

[0023] Preferably, a discharge switch is provided on the side wall of the barrel above the unloading area on a side away from the refrigeration and air supply area, and the discharge switch is electrically connected to the first motor and the second motor.

[0024] The discharging switch can be used to control the start and stop of the first motor and the second motor, thereby facilitating the control of the rotation timing of the rotating baffle and the spiral auger, facilitating the uniform removal of grains and beans, and preventing a large amount of grains and beans from falling and leaking.

[0025] Preferably, an exhaust port is provided on the top partition between the refrigeration air supply area and the loading area, and an air inlet is provided on the bottom partition between the refrigeration air supply area and the unloading area; the refrigeration system includes an evaporator, a condenser, a compressor and an expansion valve, the condenser is arranged on the side of the refrigeration air supply area close to the exhaust port, the evaporator is arranged on the side of the refrigeration air supply area close to the air inlet and is located above the water receiving plate, and the evaporator and condenser are separated by a partition in the refrigeration air supply area.

[0026] The low-pressure refrigerant in the evaporator is compressed into high-pressure hot steam by the compressor, which is condensed into high-pressure liquid in the condenser to release heat. The high-pressure liquid refrigerant is converted into low-pressure liquid through the expansion valve to control the flow of refrigerant entering the evaporator. The liquid refrigerant in the evaporator absorbs heat to lower the ambient temperature of the environment around the evaporator, and then releases heat through the condenser, continuously circulating to achieve refrigeration; the dry and cold air around the evaporator is introduced into the unloading area through the air inlet, and then the dry and cold air is introduced into the loading area from the unloading area through the air supply inclined plate from bottom to top, so as to take away the hot and humid air inside the grain and beans stored in the loading area, and the hot and humid air in the loading area is discharged through the exhaust port. The water vapor and heat in the loading area are reduced through heat exchange, so that the grain and beans are kept in a low-temperature, dry environment, thereby extending the storage period of the grain and beans and maintaining their freshness and nutritional value.

[0027] Preferably, a heat dissipation port is provided on the side wall of the barrel body on the side close to the condenser, and an exhaust fan is provided in the heat dissipation port; an air inlet is provided on the side wall of the barrel body on the side close to the evaporator.

[0028] The exhaust fan in the heat dissipation port can be used to remove the heat generated by the condenser heat exchange and the hot and humid air near the exhaust port in time, and at the same time reduce the pressure near the exhaust port, so that the outside air can be replenished into the evaporator. After absorbing heat and dehumidifying in the evaporator, the air is replenished into the loading area through the air supply inclined plate in the unloading area, taking away the moisture and heat of the grain or beans in the loading area, and then extracted by the exhaust fan. This cycle achieves the purpose of dehumidification and drying.

[0029] Preferably, the water receiving plate is arranged at an angle and the top of the water receiving plate is fixedly connected to the inner wall of the barrel body in the refrigeration and air supply area away from the air inlet. A gap is provided between the bottom of the water receiving plate and the partition. The refrigeration and air supply area is connected with the water receiving area through the gap. A pull-out water receiving box is provided in the water receiving area.

[0030] Since the evaporator is located above the water receiving plate, after the external air enters the refrigeration air supply area under the action of pressure, it first passes through the evaporator and then enters the unloading area through the air inlet. When the external air passes through the evaporator, the low temperature environment on the surface of the evaporator can first cool the passing gas to below the dew point, so that the water vapor in the air condenses into water droplets and adheres to the surface of the evaporator. The collected water droplets can fall on the water receiving plate and are guided by the water receiving plate to be discharged into the water receiving box below the water receiving plate, thereby achieving the purpose of cooling and dehumidifying the air supplied from the outside to the loading area, and preventing the grain and beans in the loading area from coming into contact with the external hot and humid air during ventilation, absorbing moisture and condensing, and causing mildew.

[0031] Preferably, a barrel opening is provided on the top of the barrel body, and the shape and size of the bottom of the barrel cover are adapted to the shape and size of the barrel opening.

[0032] The barrel cover makes it easy to add grains and beans into the holding area inside the barrel.

[0033] Preferably, a sealing ring is provided on the side of the bottom of the barrel cover.

[0034] The sealing ring can make the barrel lid and the barrel body fit more tightly, and at the same time prevent external hot and humid air or insects and rats from entering the barrel body through the barrel opening. BRIEF DESCRIPTION OF THE DRAWINGS

After being concentrated in the lower hopper 123, they continue to fall downward into the lower pipe 124, which is convenient for accommodating grains or beans of different particle sizes and preventing large grains of grains and beans from piling up and causing blockage.

[0052] Reference Figure 3 As shown, in this embodiment, a spiral auger 1241 is provided in the discharge pipe 124, and a second motor 1242 is fixed to the end of the discharge pipe 124 away from the discharge hopper 123, and the spiral auger 1241 is connected to the power output end shaft of the second motor 1242; an opening is provided at the bottom of the discharge pipe 124, and the discharge pipe 124 is connected to the bottom of the discharge area 12 through the opening; a pull-out receiving box 3 is provided at the bottom of the discharge area 12, and a handle 33 is provided on the outer wall of the receiving box 3.

[0054] Reference Figure 3 or Figure 6As shown, in this embodiment, an exhaust port 141 is provided on the partition 13 at the top between the refrigeration air supply area 14 and the receiving area 11, and an air inlet 142 is provided on the partition 13 at the bottom between the refrigeration air supply area 14 and the unloading area 12; the refrigeration system includes an evaporator 143, a condenser 145, a compressor and an expansion valve, the condenser 145 is arranged on the side of the refrigeration air supply area 14 close to the exhaust port 141, the evaporator 143 is arranged on the side of the refrigeration air supply area 14 close to the air inlet 142 and is located above the water receiving plate 148, the evaporator 143 and the condenser 145 are separated by the partition 13 in the refrigeration air supply area 14, and the low-pressure refrigerant in the evaporator 143 is compressed into high-pressure hot steam by the compressor, so that it is condensed into high-pressure liquid in the condenser 145, releasing heat, The high-pressure liquid refrigerant is converted into a low-pressure liquid through the expansion valve, and the flow rate of the refrigerant entering the evaporator 143 is controlled. The liquid refrigerant in the evaporator 143 absorbs heat to lower the temperature of the environment around the evaporator 143, and then releases heat through the condenser 145, continuously circulating to achieve refrigeration; the dry and cold air around the evaporator 143 is passed into the unloading area 12 through the air inlet 142, and then the dry and cold air is passed from the unloading area 12 into the loading area 11 from bottom to top through the air supply inclined plate 111, so as to take away the hot and humid air inside the grain and beans stored in the loading area 11, and the hot and humid air in the loading area 11 is discharged through the exhaust port 141.

[0056] Reference Figure 3As shown, in this embodiment, the water receiving plate 148 is tilted and the top of the water receiving plate 148 is fixedly connected to the inner wall of the barrel body 1 on the side away from the air inlet 142 in the cooling air supply area 14. A gap is provided between the bottom of the water receiving plate 148 and the partition 13. The cooling air supply area 14 is connected to the water receiving area 15 through the gap. A removable water receiving box 4 is provided in the water receiving area 15. Since the evaporator 143 is located above the water receiving plate 148, the external air enters the cooling air supply area 14 under the action of pressure, first passes through the evaporator 143 and then enters through the air inlet 142. When entering the unloading area 12, when the external air passes through the evaporator 143, the low temperature environment on the surface of the evaporator 143 can first cool the passing gas to below the dew point, so that the water vapor in the air condenses into water droplets and adheres to the surface of the evaporator 143. The water droplets gather and fall on the water receiving plate 148. The water droplets are guided by the water receiving plate 148 and discharged into the water receiving box 4 below the water receiving plate 148, thereby achieving the purpose of cooling and dehumidifying the air supplied from the outside to the holding area 11, and preventing the grains and beans in the holding area 11 from coming into contact with the external hot and humid air during ventilation, absorbing moisture and condensing, and causing mildew.

[0057] Reference Figure 1 As shown, in this embodiment, a barrel opening 18 is provided on the top of the barrel body 1, and the shape and size of the bottom of the barrel cover 2 are adapted to the shape and size of the barrel opening 18, so that grains and beans can be easily added to the receiving area 11 in the barrel body 1 through the barrel cover 2.

[0058] Reference Figure 1 As shown, in this embodiment, a sealing ring 21 is provided on the side of the bottom of the barrel cover 2. The sealing ring 21 can make the barrel cover 2 and the barrel body 1 fit more tightly, and at the same time prevent external hot and humid air or insects, rats, etc. from entering the barrel body 1 from the barrel mouth 18.

[0059] Example 2

[0060] When storing grain or beans, first open the barrel lid 2 to expose the barrel opening 18, then pour the grain or beans to be stored into the barrel body 1 through the barrel opening 18. The grain or beans poured into the barrel body 1 fall on the two inclined air supply inclined plates 111. The storage pipe 122 and the rotating baffle 1221 in the storage pipe 122 are located below the gap between the two air supply inclined plates 111, which can prevent the grain and beans from falling out from the gap between the two air supply inclined plates 111. After pouring, cover the barrel lid 2 and tightly fit the barrel lid 2 and the barrel body 1 through the sealing ring 21 on the bottom side of the barrel lid 2.

[0061] When the intelligent grain and bean storage barrel is working, the ambient temperature of the grain and bean storage can be set by the controller 16 as needed, and the CCD camera 125 can be used to take photos and samples to identify the type of stored grain. Then, the temperature inside the barrel body 1 is controlled within the optimal range by combining the controller 16, the refrigeration system and the temperature sensor 127;

[0062] When the refrigeration system is working, the compressor compresses the low-pressure refrigerant into high-pressure hot steam, which is condensed into high-pressure liquid in the condenser 145, releasing heat. The hot air near the condenser 145 is continuously discharged from the heat dissipation port 147 through the exhaust fan 146. The expansion valve converts the high-pressure liquid refrigerant into a low-pressure liquid and controls the flow of the refrigerant into the evaporator 143. The refrigerant absorbs heat and becomes a low-pressure gas during the evaporation process, which reduces the ambient temperature of the evaporator 143. The refrigerant then releases heat through the condenser 145, and the cycle continues to achieve refrigeration. During the refrigeration process, the heat dissipation fan continuously extracts the hot air around the condenser 145, so that the hot and humid air inside the barrel body 1 is also discharged from the heat dissipation port 147. The internal air pressure of the barrel body 1 is reduced, so that the external air pressure passes through the air inlet 144, the evaporator 143, the air inlet 142 and the air supply inclined plate 111 in sequence, and is replenished into the receiving area 11 in the barrel body 1.

[0063] In the process of external air pressure entering the barrel body 1, when the external hot and humid air passes through the evaporator 143, due to the low temperature around the evaporator 143, the heat in the air flowing through the evaporator 143 is continuously taken away by the refrigerant in the evaporator 143, thereby reducing the temperature of the air replenished into the barrel body 1 from the outside through the evaporator 143. At the same time, due to the low temperature around the evaporator 143, the moisture contained in the external air condenses after encountering the evaporator 143, forming water droplets and adhering to the surface of the evaporator 143. The water droplets condensed on the surface of the evaporator 143 gradually increase and gather, and then drip downward onto the water receiving plate 148 under the action of gravity. The condensed water droplets are guided and discharged into the water receiving box 4 through the water receiving plate 148, thereby reducing the humidity of the air replenished into the barrel body 1 from the outside through the evaporator 143, preventing the external air from entering the barrel body 1 and condensing on the surface of the stored grains and beans, causing the grains and beans to become moldy;

[0064] After the outside air is cooled and dehumidified by the evaporator 143, it becomes dry and cold air. The dry and cold air passes through the air supply inclined plate 111 and is replenished into the storage area 11. As the dry and cold air moves upward through the air supply inclined plate 111 and the gaps between the grain and beans stored thereon, the dry and cold air removes the heat and moisture in the grain and beans through the air flow and heat exchange characteristics. The dry and cold air is then sucked by the exhaust fan 146 and discharged out of the heat dissipation vent 147 along with the heat emitted by the condenser 145. This reduces the temperature and humidity in the storage area 11 where the grain and beans are stored, thereby slowing down the physiological metabolism of the grain and beans and inhibiting the growth and reproduction of microorganisms and pests, thereby achieving the purpose of extending the storage time of grain and beans.

[0065] During the cooling process, the refrigeration system monitors the temperature in the receiving area 11 in real time through the temperature sensor 127 on the top of the receiving area 11, and then compares it according to the set temperature range. After reaching the appropriate temperature, the temperature is controlled by adjusting the working state of the evaporator 143 and the operating speed of the compressor until the temperature drops to within the set range, thereby preventing the grain and beans from suffering from cold damage and resulting in quality degradation due to excessive temperature; the humidity sensor 128 monitors the humidity in the receiving area 11 in real time, and controls the cooling capacity of the evaporator 143 by controlling the flow rate of the refrigerant in the evaporator 143 by adjusting the working state of the evaporator 143 and the operating speed and operating time of the compressor, so as to enable the air added from the outside to the receiving area 11 to condense the water vapor in the air when passing through the evaporator 143, thereby preventing the water vapor from entering the receiving area 11 with the air and condensing on the surface of the grain and beans, causing the grain and beans to become moldy.

[0066] The refrigeration system is used to lower the temperature of the grain and bean storage environment, and the temperature and humidity are monitored in real time to keep the grain and beans in a low-temperature, dry environment. The moisture content of the grain and beans is reduced to prevent internal moisture and heat accumulation, moisture absorption, condensation and mildew. The temperature is lowered to slow down the physiological metabolism of the grain and beans, inhibit the growth and reproduction of microorganisms and pests, thereby extending the storage time of grain and beans and ensuring the quality of the stored grain and beans.

[0067] Example 3

[0068] When it is necessary to take out grains and beans, the first motor 1222 and the second motor 1242 are controlled to rotate by the discharge switch 17. When the first motor 1222 rotates, the grains or beans fall onto the top of the rotating baffle 1221 under the action of gravity. Since the cross section of the rotating baffle 1221 is radial, the fallen grains or beans fall between each two adjacent baffles 121 above the rotating baffle 1221, and then are discharged downwardly into the lower hopper 123 as the rotating baffle 1221 rotates. Flexible baffles are installed on the top of each radial baffle on the rotating baffle 1221 to prevent grain and bean particles from getting stuck in the opening between the rotating baffle 1221 and the top of the storage tube 122 during the rotation of the rotating baffle 1221.

[0069] The grain or beans that fall into the lower hopper 123 are guided by the lower hopper 123 to fall into the lower feeding pipe 124, and the second motor 1242 rotates to drive the spiral screw 1241 to rotate in the lower feeding pipe 124, pushing the grain or beans in the lower feeding pipe 124 to the opening at the bottom of the other end of the lower feeding pipe 124. Since the lower feeding pipe 124 is connected with the lower feeding area 12 through the opening, the grain and beans eventually fall from the opening at the bottom of the lower feeding pipe 124 to the receiving box in the lower feeding area 12. After taking out the required amount of grain and beans, the discharge switch 17 is disconnected to stop the rotation of the first motor 1222 and the second motor 1242, and the grain and beans no longer continue to fall downward. The falling speed of the grain and beans is controlled by the storage pipe 122, the lower hopper 123 and the lower feeding pipe 124, so that the grain and beans fall into the receiving box at a uniform speed, which is convenient for controlling the amount of grain and beans received and preventing insects and rodents from entering.
