Device for cooling fruits and vegetables with cold water

Abstract

The invention discloses a device and a method for cooling fruits and vegetables with cold water. The device comprises a water tank, a conveying belt, a cooler, an electric motor, a temperature measurement device and a control device, wherein the electrical motor drives the conveying belt to convey fruits and vegetables to pass through the water tank, and the cooler cools water in the water tank to be kept at the environment temperature; a data acquisition module and a program control module capable of operating acquired data in real time and sending an instruction are arranged in the control device, the temperature measurement device measures the temperature of the water tank in real time, and the control device acquires the temperature parameters measured by the temperature measurement device in real time and controls the rotating speed of the electric motor and the refrigeration speed of the cooler according to the acquired temperature parameters in real time. The device can intelligently control the temperature in a cooling water tank in a continuous cold water cooling device.

Description

technical field [0001] The invention belongs to the technical field of food cooling processing, in particular to a fruit and vegetable cold water cooling device. Background technique [0002] The cold water cooling treatment of fruits and vegetables is a commonly used method of fruit and vegetable pretreatment. Fruits or vegetables generally need cold water cooling after blanching before being quick-frozen. This process can improve the quality of fruits and vegetables after cooling. [0003] Chinese patent 201420398458.2 discloses a cooling device for fruits and vegetables, which includes a cooling tank. Metal mesh and screens are arranged in the cooling tank in sequence from bottom to top. The two opposite sides of the cooling tank are connected with water pipes through support rods, and the water pipes are evenly opened. Small holes, the side of the cooling tank is provided with a drain port, the drain port is provided with a filter screen, one side of the cooling tank adj...

AI Technical Summary

Problems solved by technology

[0005] It can be seen from the above scheme that water cooling is widely used in fruit and vegetable cooling processing. However, in the cold water cooling process, the ambient temperature of the cooling water is not detected, and the parameters in the water cooling process are not intelligently controlled automatically. This may As a result, the final processing quality of fruits and vegetables will fluctuate, making it difficult to maintain stable quality of processed fruits and vegetables

[0006] Because in the water cooling process, fruits and vegetables are continuously sent into the cooling tank, the feeding of fruits and vegetables to be cooled will definitely affect the cooling water environment, such as the temperature of the cooling water, the change of the cooling water temperature will directly affect the cooling effect of the fruits and vegetables, and then It is difficult to guarantee the final quality stability of cooled fruits and vegetables
