A kind of muddy ice slurry with high ice content and preparation method thereof

Abstract

The invention discloses a muddy ice slurry with high ice content and a preparation method thereof. The ice slurry is composed of solvent, polyvinyl alcohol, glycerol, borax, ethylene glycol, polyoxyethylene sorbitan fatty acid ester and Polyethylene oxide propylene oxide glyceryl ether is prepared; based on the solvent quality, the mass percentages of other components are respectively 0.5-1.5% of polyvinyl alcohol, 1.0-2.0% of glycerol, 0.1-1.0% of borax, Ethylene glycol 1.0-3.0%, polyoxyethylene sorbitan fatty acid ester 1.0-2.0%, polyethylene oxide propylene oxide glyceryl ether 0.1-1.0%, the ice slurry prepared by the invention has good fluidity and does not stick to the wall , so that the ice slurry produced in the same time has a higher ice content rate, which improves the refrigeration efficiency and makes full use of the latent heat of the ice slurry.

Description

technical field

[0001] The invention relates to the technical field of ice slurry preparation, in particular to a muddy ice slurry with high ice content and a preparation method thereof. Background technique

[0002] Ice slurry is a solid-liquid two-phase fluid with good fluidity composed of solution and ice crystal particles. Because of its good heat transfer characteristics and high density of latent heat storage, it is widely used in construction, medicine, food refrigeration, mine cooling and other fields. It has broad application prospects, but the existing ice slurry has poor fluidity, so it is easy to stick to the wall and has a low ice content.

[0003] The existing technologies for preparing ice slurry mainly include supercooled water ice making technology, water jet evaporative ice making, and silicone oil emulsion ice making.

[0004] Supercooled water ice making technology: When water or aqueous solution is cooled to a supercooled state in the evaporating coil, ...
