Abstract

The invention provides a multistage fruit and vegetable precooling machine. The multistage fruit and vegetable precooling machine comprises a conveyor belt, a first precooling unit and a second precooling unit, wherein the first precooling unit is arranged on the conveyor belt; the second precooling unit is arranged on the conveyor belt and positioned at the lower reach of the first precooling unit; the first precooling unit and the second precooling unit supply cooling water for precooling fruits and vegetables, the temperature of the cooling water supplied by the first precooling unit is higher than that of the cooling water supplied by the second precooling unit. According to the technical scheme disclosed by the invention, the problem that cold damage is caused for the fruits and the vegetables because the single-stage precooling temperature for the fruits and the vegetables in the prior art is too low can be effectively solved.

Description

Technical field [0001] The invention relates to the technical field of fruit and vegetable pre-cooling, in particular to a multi-stage fruit and vegetable pre-cooling machine. Background technique [0002] At present, in order to ensure the freshness of fruits and vegetables during transportation, some fruits and vegetables are pre-cooled with water. Pre-cooled fruits and vegetables will maintain their nutritional value and commerciality for a long time. The existing water pre-cooling method directly brings fruits and vegetables into contact with low-temperature water to reduce the temperature of the fruits and vegetables to complete the pre-cooling process. However, when some fruits and vegetables are in direct contact with water with too low temperature, they will be cooled in the later stage because the temperature drops too fast. Cold damage occurs during chain logistics and shelf life. [0003] Take cowpea as an example, cowpea is rich in nutrients, rich in protein, carbohyd...
