Description

Technical Field

[0001] The utility model relates to the field of corn processing, in particular to a cooling spray device. Background Art

[0002] Corn cooling spray is a technology used for post-processing of agricultural products, especially for rapid cooling of corn after harvest. The purpose of this technology is to reduce the temperature in the corn cob to prevent the grain from heating and mildewing, thereby extending the storage time of corn and maintaining its quality. The working principle of corn cooling spray is usually to reduce the temperature of the corn cob by spraying a coolant (such as water). The coolant is sprayed evenly on the corn cob through the spray system, and the heat is transferred to the coolant by conduction, convection and radiation, so that the coolant evaporates and takes away the heat, thereby reducing the temperature of the corn. The benefits of corn cooling spray technology include: Rapid cooling: The temperature of the corn cob can be reduced to the desired level in a shorter time. Energy saving: Spray cooling is generally more energy-efficient than traditional air cooling. Quality retention: Through rapid cooling, the freshness and nutritional value of corn can be better maintained. Extended storage time: The cooled corn can maintain a lower temperature during storage, reducing grain losses.

[0003] After searching, the utility model patent with Chinese patent number CN217817690U discloses a centralized cooling equipment for corn processing, including a cooling box, a controller is installed at the front end of the cooling box, a material guide pipe runs through the interior of the cooling box, a feed hopper is arranged at the upper end of the material guide pipe, a discharge pipe is arranged at the lower end of the material guide pipe, a drainage hole is opened on the outer surface of the side end of the material guide pipe, and a drive motor is installed at the right end of the material guide pipe. By arranging a fan, a heat dissipation groove, a water pump, a connecting pipe and a sprinkler head, not only the cooling effect of the corn is better, but also the cooling water is recycled, thereby saving water resources. By arranging a material guide pipe, a feed hopper, a discharge pipe, a drainage hole, a drive motor, a connecting shaft, a bearing seat and a spiral sheet, not only the contact area between the corn and the cooling water is increased and the cooling time of the corn is shortened, but also the cooled corn is automatically conveyed and collected.

[0004] However, when cooling the corn, the cooling water that contacts the corn and is evaporated by the temperature of the corn will be discharged to the outside, and the water contained in the additional cooling water will be wasted to a certain extent. In addition, since the guide pipe is generally configured to be cylindrical, although its outer surface is provided with drainage holes, the cooling water does not directly contact the corn, which affects the efficiency of corn cooling.

[0005] How to invent a cooling spray device to improve these problems has become an urgent problem to be solved by technicians in this field. Utility Model Content

[0006] In order to make up for the above deficiencies, the utility model provides a cooling spray device, which aims to improve the problem that the cooling water that contacts the corn and is evaporated by the temperature of the corn will be discharged to the outside, and the water contained in the additional cooling water will cause a certain degree of waste. Moreover, since the guide pipe is generally arranged in a cylindrical shape, although drainage holes are opened on its outer surface, the cooling water does not directly contact the corn, thereby affecting the cooling efficiency of the corn.

[0026] When in use, cooling water is added into the cooling chamber 1 through the water inlet pipe 13. After the water is filled, the drain pipe 14 is opened so that the water inlet amount of the water inlet pipe 13 is equal to the water discharge amount of the drain pipe 14. Then the motor 6 and the water pump 15 are started. The water pump 15 extracts cooling water through the water pumping pipe 16.

When the corn reaches the inside of the cooling chamber 1, the cooling water sprayed by the nozzle 18 will act on the corn to cool the corn. The corn will finally be discharged through the discharge hopper 5.

[0027] By setting the "V"-shaped cooling pipe 3 in the cooling chamber 1, the cooling water sprayed from the nozzle 18 can directly contact the corn, so that the cooling water can directly cool the corn, reducing the temperature loss of the cooling water and improving the cooling efficiency.
