Problems solved by technology

The device uses a fan to blow the wind into the middle ventilation pipe, and the air is released through the ventilation holes provided around the ventilation pipe. The temperature can be reduced to the same level, which overcomes the shortcomings of the traditional bottom ventilation and cooling, and has a water spray function. After washing and cooling by spraying water, the cylinder rotates and the middle pipe is ventilated horizontally to accelerate the cooling and dehydration treatment. The cooling speed is faster than Conventional bottom ventilation cooling is 1.5-2 times faster

Abstract

The invention discloses a movable agriculture product precooling device and precooling method, and belongs to the technical field of fresh keeping of agriculture products. The movable agriculture product precooling device comprises a collector drum body, a barrow and a ventilation pipe, wherein the collector drum body and the ventilation pipe are coaxially fixed on the barrow; the ventilation pipe is arranged in the collector drum body, and the bottom of the ventilation pipe communicates with a fan; the fan is fixed on the barrow, and ventilation holes are formed in the collector drum body and the ventilation pipe in a circumferential direction; a water way is also arranged on the body of the ventilation pipe, and the water way is arranged in the length direction of the ventilation pipe between adjacent ventilation holes; water dispersing holes are uniformly formed in the water way in the length direction of the ventilation pipe; and the water way communicates with one water supply water pump which is fixed on a movable device. The movable agriculture product precooling device has the function of spraying water, after water is sprayed for washing and the temperature is reduced, through rotation of a drum and transversal ventilation of a middle pipe, reducing of temperature and dehydration treatment are accelerated, and the speed of reducing the temperature is 1.5-2 times higher than that of reducing the temperature in the manner of ventilation in bottom in the prior art, and the movable agriculture product precooling device can complete treatment of reducing the temperature or reducing moisture for agriculture products in various occasions.

Description

technical field [0001] The invention belongs to the technical field of fresh-keeping of agricultural products, and in particular relates to a mobile pre-cooling device and a pre-cooling method for agricultural products. Background technique [0002] Low temperature is an important factor to ensure the freshness of agricultural products. Low temperature is beneficial to reduce the physiological metabolic process of agricultural products, reduce the activity of enzymes in tissues and inhibit the infection of harmful organisms, thus effectively prolonging the freshness and storage period of agricultural products. The freshly harvested agricultural products carry a lot of field heat. If the agricultural products are not pre-cooled in time, the air exhaled by the agricultural product tissue under low temperature conditions will easily produce condensation water and adhere to the surface of the product, leading to microbial growth or infection. Tropical and subtropical fresh agri...
