Description

Technical Field

[0001] The utility model relates to the technical field of sweet potato storage devices, in particular to a constant temperature and humidity adjustment cabinet for storing sweet potatoes. Background Art

[0002] Sweet potatoes are a common food crop and cash crop, rich in nutrients such as starch, dietary fiber, and vitamins, and have high edible value and economic value. The storage of sweet potatoes is crucial for ensuring the quality of sweet potatoes and extending their shelf life. Appropriate storage conditions can reduce the rot, sprouting, and deterioration of sweet potatoes, and improve the utilization rate and economic benefits of sweet potatoes.

[0003] Traditional sweet potato storage methods usually stack sweet potatoes in warehouses or cabinets. This method easily leads to poor air permeability between sweet potatoes. During storage, sweet potatoes carry out respiration, generating carbon dioxide and heat. If the air permeability is not good, carbon dioxide cannot be discharged in time, and heat will also accumulate, easily causing sweet potatoes to rot. In addition, stacking sweet potatoes for storage is also prone to causing extrusion damage, further accelerating the rot of sweet potatoes.

[0004] The storage of sweet potatoes requires appropriate temperature and humidity conditions. Traditional storage devices usually cannot accurately control the temperature and humidity. Too high or too low temperature, too high or too low humidity will affect the quality and shelf life of sweet potatoes. For example, too high a temperature will accelerate the sprouting and rot of sweet potatoes, and too high humidity is likely to cause sweet potatoes to mold. Traditional storage devices often can only rely on the natural environment to adjust the temperature and humidity, unable to meet the needs of sweet potato storage. Summary of the Utility Model

[0033] In this embodiment, as a preferred technical solution, the multi-layer storage rack 3 includes a plurality of storage layers 14 distributed vertically. Adjacent storage layers 14 are fixedly connected by vertical rods 15. The storage layer 14 is in a circular ring structure and a passage 6 for the air supply duct 5 to pass through is provided at the center. The side and bottom surfaces of the storage layer 14 are both hollow structures, and a plurality of air outlet holes 16 are provided on the side surface of the air supply duct 5 corresponding to each storage layer 14.

[0034] A constant temperature and humidity regulation cabinet for sweet potato storage further includes a temperature and humidity control unit. The temperature and humidity control unit includes a temperature sensor 18 and a humidity sensor 19 fixedly arranged on the inner wall of the cabinet body 1, and further includes a PLC controller 20 fixedly arranged outside the cabinet body 1. The temperature sensor 18, the humidity sensor 19, the fan 8 and the humidification and temperature increase component are all electrically connected to the PLC controller 20.

[0035] The working principle of the constant temperature and humidity regulation cabinet for sweet potato storage of the present utility model is as follows: The temperature and humidity conditions inside the cabinet body 1 are monitored in real time by the temperature sensor 18 and the humidity sensor 19 in the temperature and humidity control unit. When the temperature or humidity is lower than the preset value, the PLC controller 20 starts the humidification and temperature increase component to work. Air enters the humidification chamber 9 from the air inlet grille 11, the humidifier 12 humidifies the air, and then the air enters the temperature increase chamber 10, and the electric heating coil 13 heats the air. The heated and humidified air is sucked by the blower 4 and sent into the cabinet body 1 through the air supply duct 5. The air outlet holes 16 on the side surface of the air supply duct 5 blow the air evenly onto the sweet potatoes on the multi-layer storage rack 3, providing a suitable temperature and humidity environment for the sweet potatoes. When the temperature or humidity is higher than the preset value, the PLC controller 20 starts the fan 8 to work, exhausting the hot and humid air inside the cabinet body 1 to achieve dehumidification and temperature reduction.

[0036] The using process of the constant temperature and humidity regulation cabinet for sweet potato storage of the present utility model is as follows:

[0037] 1. Preparation work: Check whether all components of the regulation cabinet are in good condition, and confirm that devices such as the temperature sensor 18, the humidity sensor 19, the PLC controller 20, the blower 4, the humidifier 12, the electric heating coil 13 and the fan 8 are operating normally. Set a suitable temperature and humidity range through the PLC controller 20 according to the storage requirements of sweet potatoes.

[0038] 2. Place sweet potatoes: Open the cabinet door 2 and evenly place the sweet potatoes on each storage layer 14 of the multi-layer storage rack 3. Since the storage layer 14 is in a circular ring structure and both the side and bottom surfaces are hollow structures, and a passage 6 for the air supply duct 5 to pass through is provided at the center, good air permeability between the sweet potatoes can be ensured.

[0039] 3. Start the regulation cabinet: Close the cabinet door 2, start the PLC controller 20, and the regulation cabinet starts to work. The temperature sensor 18 and the humidity sensor 19 monitor the temperature and humidity conditions inside the cabinet body 1 in real time and transmit the data to the PLC controller 20.

[0040] 4. Temperature and humidity regulation: When the temperature or humidity inside the cabinet body 1 is lower than the preset value, the PLC controller 20 starts the humidifying and warming component to work. After the air is humidified in the humidifying chamber 9 and heated in the warming chamber 10, it is sent into the cabinet body 1 by the blower 4 through the air supply duct 5 to provide a suitable temperature and humidity environment for the sweet potatoes. When the temperature or humidity inside the cabinet body 1 is higher than the preset value, the PLC controller 20 starts the fan 8 to work, and discharges the hot and humid air inside the cabinet body 1 through the exhaust port 7 to achieve dehumidification and cooling. At the same time, the check valve 17 outside the fan 8 can prevent external air from flowing back.

[0041] 5. Observe the storage situation: Users can observe the storage situation of the sweet potatoes inside the cabinet body 1 at any time through the transparent observation window 21 on the cabinet door 2, without frequently opening the cabinet door, reducing the fluctuation of temperature and humidity.

[0042] 6. Maintenance and upkeep: Regularly check the operation of each component of the regulation cabinet, and repair or replace it in time if there is a fault. Clean the inside of the cabinet body 1 and the multi-layer storage rack 3 to keep the equipment clean and hygienic. Adjust the temperature and humidity settings in a timely manner according to the storage time and quality change of the sweet potatoes.

[0043] The above describes the present utility model and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. All in all, if those of ordinary skill in the art are inspired by it and, without departing from the gist of the creation of the present utility model, design similar structural manners and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present utility model.
