Description

Technical Field

[0001] The invention relates to the technical field of vegetable processing, and in particular to a reversible continuous loading vegetable pre-cooling device. Background Art

[0002] The effects of vegetable pre-cooling are mainly reflected in the following aspects. First, pre-cooling can quickly lower the temperature of vegetables, inhibit respiration, reduce the consumption of nutrients and the generation of heat, thereby delaying the aging and deterioration of vegetables. Second, pre-cooling can quickly remove the field heat of vegetables and prevent them from rotting and deteriorating due to high temperatures during transportation and storage. In addition, pre-cooling can also lower the temperature, reduce water evaporation, and maintain the freshness and crisp taste of vegetables. The low temperature environment can also inhibit the growth and reproduction of microorganisms, reducing the risk of vegetable rot and mildew. Through these measures, pre-cooling significantly extends the shelf life of leafy vegetables.

[0003] The vegetable air-cooling precooling device is a highly efficient cooling equipment, mainly composed of a refrigeration system, a fan, an air duct, a temperature control system and a precooling chamber. The device uses forced air circulation for cooling, and uses the cold air flowing through the surface of the vegetables to take away heat and achieve rapid cooling. Its air duct design and temperature control system ensure that the cold air is evenly distributed and the temperature is stable. It is suitable for a variety of leafy vegetables such as Chinese cabbage, spinach, and leeks. The leafy vegetables are transported to the top conveyor belt of the vegetable precooling box body through the lifting device. The leafy vegetables move forward continuously under the drive of the conveyor. At the same time, the humidified cold air flows through the air outlet to cool and precool the leafy vegetables. When the leafy vegetables move to the end of the conveyor belt, they fall to the next conveyor belt and complete the reversal action. They continue to cool and precool on the next conveyor belt. This is repeated several times to complete the precooling operation of the leafy vegetables and finally transport them to the outside of the vegetable precooling box body. During the precooling process, the cold air is reused to save precooling energy.

[0004] When vegetables move on the conveyor belt, there is no function to flip leafy vegetables. During the conveying process, the bottom of the leafy vegetables contacts the surface of the conveyor belt, while the upper part is exposed to the outside, resulting in the upper part of the leafy vegetables receiving more cold air, while the lower part receives relatively less cold air due to continuous contact with the conveyor belt, resulting in uneven cooling of the leafy vegetables during the pre-cooling process and inability to achieve uniform pre-cooling. Therefore, personnel in this technical field provide a flippable continuous loading vegetable pre-cooling device to solve the problems raised in the above background technology.

[0041] Working Principle: When in use, leafy vegetables are first transported to the conveyor belt 204 located at the feed inlet 101 through the lifting device. Multiple servo motors and multiple conveyor rollers 203 are started to rotate. The multiple rotating conveyor rollers 203 drive the multiple conveyor belts 204 to rotate in sequence, facilitating continuous loading of leafy vegetables. Driven by the conveyor belt 204, the leafy vegetables enter the vegetable pre-cooling box body 1 from the feed inlet 101. As the conveyor belt 204 moves, the vegetables gradually penetrate deeper into the pre-cooling box. During this process, the vegetables exchange heat with the cooling medium in the pre-cooling box, such as cold air, to achieve rapid pre-cooling.

Before this, the vegetables are transported by the conveyor belt 204 and fall to the top of the multiple groups of receiving plates 303. At this time, the multiple groups of rotating receiving plates 303 drive the vegetables to turn over, realizing the turning of the vegetables during the transportation process, increasing the contact area between the vegetables and the cold air, and improving the pre-cooling efficiency. At the same time, the turning action of the multiple groups of receiving plates 303 is uniform and continuous, ensuring the stability of the vegetables during the turning process and avoiding damage to the vegetables caused by violent shaking;

[0043] In the process of the multiple groups of conveyor belts 204 conveying the vegetables in sequence, the dirt and water stains carried by the vegetables are still attached to the surface of the multiple groups of conveyor belts 204. At this time, the multiple groups of conveyor belts 204 that rotate in coordination with the multiple groups of second mounting frames 311 and the multiple groups of cleaning brushes 313 are used to clean the dirt remaining on the multiple groups of conveyor belts 204. The cleaned dirt and water stains fall into the interior of the receiving groove 310. At this time, the multiple groups of second rotating rods 309 drive the multiple groups of second rotating rods 309 to rotate, and at the same time, the third belt drives the first gear 317 thereon to rotate. The first gear 317 drives the other groups of first gears 317 to rotate synchronously through the belt, and the multiple groups of first gears 317 drive the multiple groups of second gears 318 to rotate. The multiple groups of second gears 318 drive the multiple groups of extension rods 316 to rotate. The multiple groups of extension rods 316 drive the multiple groups of screw rods 314 to rotate. The multiple groups of screw rods 314 drive the multiple groups of push plates 315 to move inside the multiple groups of receiving grooves 310, pushing the dirt and water stains collected inside the multiple groups of receiving grooves 310 out of their outlets, thereby achieving the function of cleaning the surfaces of the multiple groups of conveyor belts 204;

[0044] The dirt and water stains discharged from the outlets of the multiple groups of receiving grooves 310 enter the interior of the first vertical pipe 502 and the second vertical pipe 505 through the first connecting port 503, the second connecting port 504 and the third connecting port 506 connected thereto. The first vertical pipe 502 and the second vertical pipe 505 discharge the dirt and water stains into the interior of the horizontal pipe 501, and finally discharge the dirt and water stains through the slag outlet 507, thereby realizing the function of discharging the cleaned dirt and water stains.

[0045] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
