Abstract

The invention provides an immersion type fruit and vegetable pre-cooling machine, comprising a first conveying belt, a first pre-cooling unit and a second pre-cooling unit. The first pre-cooling unit is arranged on the first conveying belt, and the second pre-cooling unit is arranged on the first conveying belt and located at the downstream of the first pre-cooling unit. The first pre-cooling unit comprises a first cooling trough and a first cooling water supply device. The first cooling trough is used for containing cooling water. The first cooling water supply device is connected with the first cooling trough and supplies the cooling water to the first cooling trough. The first conveying belt passes through the first cooling trough. The temperature of the cooling water supplied by the first pre-cooling unit is higher than the temperature of cooling water supplied by the second pre-cooling unit. With the adoption of the technical scheme provided in the invention, the problem that as fruits and vegetables are pre-cooled in a single stage, the temperature is reduced too fast and causes cold damage during cold-chain transportation in the late period in the prior art can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of fruit and vegetable precooling, in particular to an immersion type fruit and vegetable precooling 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. Pre-cooled fruits and vegetables will maintain their freshness for a longer period of time. The existing pre-cooling method directly contacts the fruits and vegetables with low-temperature water to reduce the temperature of the fruits and vegetables to complete the pre-cooling. However, when some fruits and vegetables are in direct contact with the water at too low temperature, the temperature will drop too quickly due to the low temperature of the pre-cooling water. , Chilling injury is prone to occur during the later cold chain transportation. [0003] Taking cowpea as an example, cowpea is rich in nutrients, rich in protein, carbohy...
