Fruit spray pre-cooling device based on cold accumulation box

Abstract

The invention discloses a fruit spray pre-cooling device based on a cold accumulation box. The fruit spray pre-cooling device comprises a box body, a spray pre-cooling device body, a cooling device, afan, a temperature sensor and a controller; a liquid output port of the spray pre-cooling device body is formed in the upper end in the box body, the temperature sensor detects the temperature in thebox body, when the temperature is higher than a first set value, the controller controls the spray pre-cooling device body to spray cold liquid into the box body, when the temperature in the box bodyis reduced to a second set value, the controller controls the cooling device to provide cold air for the fan to be started for refrigeration, and the controller controls the fan to be started to conduct cold air blowing drying on the interior of the box body, wherein the second set value is smaller than the first set value. According to the fruit spray pre-cooling device, the cooling device provides the cold air for the fan, the fan drives the cold air to flow and be blown to fruits and vegetables in the box body, and therefore remaining condensed water on the surfaces of the fruits and vegetables is blow-dried; the fruits and vegetables are prevented from being corroded by the condensed water, the temperature in the box body is also prevented from rising, and the fruit spray pre-coolingdevice has the advantages of automatic control, pre-cooling and good effect of removing the condensated water on the surfaces of the fruits and vegetables.

Description

technical field [0001] The invention relates to a fruit spray precooling device, in particular to a fruit spray precooling device based on a cold storage box. Background technique [0002] Pre-cooling can reduce post-harvest respiratory intensity of fruits and vegetables, inhibit the release of enzymes and ethylene, reduce the physiological metabolic rate of fruits and vegetables, prevent changes in the quality of fruits and vegetables, and reduce post-harvest losses of fruits and vegetables. The quality and value in the process are of great significance. [0003] The commonly used cold water spray precooling has the advantages of fast cooling speed, uniform cooling, no dehydration phenomenon, simple equipment use, and the advantages of fresh-keeping treatment of fruit and vegetable preservatives can be used at the same time during the pre-cooling process. However, after the fruits and vegetables are sprayed and pre-cooled, there will be more water, and the condensed water ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to solve the existing problem that using a fan to blow off the water on the surface of the fruit and vegetable after spraying and precooling the fruit and vegetable will cause the temperature of the fruit and vegetable to rise, thereby greatly reducing the precooling effect of the fruit and vegetable. It provides an automatic control, precooling Fruit spray precooling device based on cold storage box with good effect of removing condensed water on the surface of fruits and vegetables
