Description

Technical Field

[0001] The utility model relates to a melon seed production device, in particular to a fragrant melon seed storage device. Background Art

[0002] Fragrant melon seeds are a popular nut in China, and a large amount of fragrant melon seeds are consumed every year in the country. The raw material of fragrant melon seeds is dried sunflower seeds. Therefore, the fragrant melon seed production industry needs to be equipped with large-capacity sunflower seed storage bins to temporarily store the raw materials of fragrant melon seeds.

[0003] To have good quality and taste of fragrant melon seeds, the storage conditions of sunflower seeds are crucial: First of all, sunflower seeds should be stored in a low-temperature and dry environment. Generally, the storage temperature is preferably controlled at 18-26°C, the temperature should not exceed 30°C, and the relative humidity should not be too high, generally below 15%, so as to prevent sunflower seeds from getting damp. Moreover, good ventilation can help prevent sunflower seeds from getting damp and moldy. Finally, it should be noted to avoid sunlight irradiation, as direct sunlight may cause the temperature of sunflower seeds to rise, accelerate their oxidation process, and thus shorten the shelf life. Therefore, existing sunflower seed storage devices are generally equipped with a temperature and humidity control system and a ventilation system to monitor the storage environment parameters of sunflower seeds in real time. However, due to the large accumulation of sunflower seeds, the air fluidity of the sunflower seeds deep in the accumulation is extremely poor, and the respiration of sunflower seeds themselves will continuously generate water vapor, carbon dioxide and temperature, which will cause a large difference in the temperature and humidity parameters of the air deep in the accumulation and the air on the surface layer. Over time, it will lead to differences in the quality of sunflower seeds in different regions. To avoid this situation as much as possible, the fragrant melon seed production industry also needs to develop a fragrant melon seed storage device that can achieve uniform control of temperature and humidity. Summary of the Invention

[0004] The utility model provides a fragrant melon seed storage device, which solves the problem in the prior art that it is impossible to ensure that the storage temperature and humidity of fragrant melon seeds at different storage depths are consistent.

[0005] The above technical problems of the present utility model are mainly solved by the following technical solutions: A fragrant melon seed storage device, characterized in that: it includes a storage tank for storing melon seeds, a bracket for fixing the storage tank, an adjustment chamber provided inside the storage tank, and a main pipeline provided inside the storage tank and communicating with the adjustment chamber. An inlet is provided on the upper side of the storage tank, and an outlet is provided on the lower side of the storage tank. A number of hollow and outwardly radiating air outlet rods and air suction rods are provided on the main pipeline, and the air outlet rods and the air suction rods are evenly and alternately distributed with each other; An air inlet pipe and an air outlet pipe communicating with the outside are provided in the adjustment chamber, a ventilation device is provided on the air outlet pipe, and a dehumidification device and a temperature control device communicating with the air inlet pipe are further provided in the adjustment chamber. The air inlet pipe and the air outlet pipe both extend to the inner end of the main pipeline; Plugs that are separated from the inner cavity of the main pipeline are provided inside both the air outlet rods and the air suction rods, ventilation holes are provided on the rod bodies of the air outlet rods and the air suction rods, and a temperature and humidity meter is further provided inside the air suction rods. An intake branch pipe communicating with the inner cavity of the air outlet rod is provided on the air inlet pipe inside the main pipeline, and an air outlet branch pipe communicating with the inner cavity of the air suction rod is provided on the air outlet pipe inside the main pipeline. Electric control valves are provided on both the intake branch pipe and the air outlet branch pipe.

[0006] The working principle of the present utility model is as follows: When the ventilation device, the dehumidification device, and the temperature control device are turned on, the ventilation device starts to suck the air outlet pipe, so that the air outlet pipe and the air outlet branch pipes and the air suction rods communicating therewith are all in a negative pressure state. The air in the storage tank will be preferentially sucked into through the ventilation holes on the air suction rod closest to it. The temperature and humidity meter inside the corresponding air suction rod can detect the real-time air temperature and humidity and send the data to the control center, while the air inlet pipe will supplement the fresh air that has been dehumidified and temperature-controlled to the storage tank through the air outlet rod. Since there are differences in the air temperature and humidity values at different depths in the storage tank, the control center can adjust according to the actually measured values. When it is measured that the air humidity and temperature in a certain area are too high, both the air outlet rod and the air suction rod near this area will remain in the working state; when it is measured that the air humidity and temperature in a certain area are both within the normal value, the air outlet rod and the air suction rod near this area will be closed. The opening and closing of the air outlet rod and the air suction rod are controlled by the corresponding electric control valves. The ventilation device, the dehumidification device, and the temperature control device of the present utility model generally work at regular intervals, starting for a period of time and then stopping for a period of time.

[0007] Further, the storage tank is composed of a stainless steel inner liner and a heat insulation layer wrapped outside it. The heat insulation layer can play a role in insulating temperature, slow down the conduction of heat, and enhance the heat insulation effect of the storage tank.

[0008] Therefore, the utility model has the following characteristics compared with the prior art: 1. By arranging multiple air outlet rods and air suction rods at different heights in the storage tank, the real-time air temperature and humidity in different height ranges can be independently detected, and by controlling the opening and closing of the electric control valves, the areas that do not meet the set values can be ventilated for a long time, while the areas that meet the set values are not supplied with air, which is beneficial to energy conservation.

At different heights, the air outlet rods and air suction rods are evenly staggered with each other, and the distance between adjacent air outlet rods and air suction rods is between 0.4 and 1.0 meters;

[0015] Refer to Figure 1 and Figure 2, an adjustment chamber is provided with an intake pipe 500 and an exhaust pipe 600 communicating with the outside. An exhaust fan device 700 is provided on the exhaust pipe.

Since there are differences in the air temperature and humidity values at different depths in the storage tank, the control center can adjust according to the actually measured values. When it is measured that the air humidity and temperature in a certain area are too high, both the air outlet rod and the air inlet rod near this area will remain in the working state; when it is measured that the air humidity and temperature in a certain area are both within the normal values, the air outlet rod and the air inlet rod near this area will be closed.

The main material of the heat preservation layer is polystyrene foam board (EPS). The heat preservation layer can play a role in insulating temperature, slowing down the conduction of heat, and enhancing the heat preservation effect of the storage tank.

Such changes are not considered to depart from the scope of the present utility model. All such modifications obvious to those skilled in the art will be included within the scope of the present claims.
