Ice crystal blocking method and device, and ice making machine

Abstract

The invention relates to the technical field of supercooled water ice making, in particular to an ice crystal blocking method and device, and an ice making machine. The ice crystal blocking method comprises the steps that a heating assembly is controlled to heat a pipe body of a supercooled water jet pipe extending into an ice slurry generator for at least a preset time; a detection signal representing the temperature of the pipe body of the supercooled water jet pipe output from a temperature sensor is received; and the detection signal is processed, and a signal representing the working state of the heating assembly is output. According to the ice crystal blocking method, the ice blockage in the pipeline can be prevented, and the ice making efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of supercooled water ice making, in particular to an ice crystal blocking method, device and ice maker. Background technique [0002] Ice blockage is prone to occur during the continuous production of binary ice by dynamic ice machines. Because ice crystals grow rapidly along the supercooled water pipeline to the plate exchange, the current blocking method is mostly to inject water at 0.5°C to form a high-temperature water film on the inner wall of the pipeline. Melting the ice crystals on the tube wall prevents the ice crystals from adhering and growing to the plate and causing blockage. However, due to the non-absolutely homogeneous change process of system pressure and water flow, the high-temperature water film is not easy to form uniformly along the pipe wall, and the temperature changes quickly and it is difficult to control the melting temperature of ice crystals, which eventually leads to ice blockag...

However, due to the non-homogeneous change process of system pressure and water flow, the high-temperature water film is not easy to form uniformly along the pipe wall, and the temperature changes quickly and it is difficult to control the melting temperature of ice crystals, which eventually leads to ice blockage and seriously affects the ice-making efficiency.
