A continuous ice production device

Abstract

The invention provides a continuous ice particle making device. The continuous ice particle making device comprises an atomizing nozzle, a swirl nozzle, an ice making compartment, a hollow pipe, a hollow circulation nozzle, a mixing chamber, a precooling chamber and the like. Water is atomized to generate water droplets through the atomizing nozzle, low-temperature swirl gas is sprayed through the swirl nozzle, the atomized water droplets are frozen to generate ice particles, and the low-temperature gas passes through the hollow circulation nozzle so as to continuously make ice particles. Under the action of swirl, injection, entrainment and mixing of the swirl nozzle and the hollow circulation nozzle, the ice particles are quickly generated, the particle size is uniform, and the intensity is high; the precooling chamber is precooled to be cool, and the cooling capacity is recycled, so that heat loss of the low-temperature gas is reduced and eliminated, and energy is saved. The system has the advantages of simple structure, small size, light weight and low manufacturing cost and can be used for continuously making the ice particles, and for example, the ice particles can be injected in application occasions such as surface cleaning, derusting, ice storage, food processing and the like.

Description

technical field [0001] The invention relates to an ice particle production device, in particular to a continuous ice particle production device. Background technique [0002] The preparation of ice particles with a certain temperature and particle size is in great demand in engineering. Finding a continuous and instant method of producing ice particles of a specific size, reducing the storage of ice particles and promoting the fluidization of ice particles is the key to accelerating the industrial application of ice particles. [0003] There are three main ways to produce ice particles. One is the physical crushing method of large ice cubes. Generally, ice cubes of appropriate size are first frozen, then crushed, and then sieved to obtain ice particles with the required particle size. It cannot be continuously produced. Round ice particles are produced, and the ice particles are easy to melt during the crushing and screening process; the second is the vacuum rapid cooling me...

[0003] There are three main ways to produce ice particles. One is the physical crushing method of large ice cubes. Generally, ice cubes of appropriate size are first frozen, then crushed, and then sieved to obtain ice particles with the required particle size. It cannot be continuously produced. Round ice particles are produced, and the ice particles are easy to melt during the crushing and screening process; the second is the vacuum rapid cooling method, which requires a complicated vacuum system, which is uneconomical, and the temperature for generating ice particles is high, and the practicability is poor; the third is refrigeration If the agent is in direct contact with the freezing method, the water droplets are easy to burst, and during the freezing process, the bonding phenomenon is serious

At present, although ice pellet production equipment is diverse and the technology is relatively mature, general ice production equipment requires large-scale crushing machinery, the system composition is complex, the volume is relatively large, the ice pellet preparation efficiency is low, and ice pellets need to be refrigerated
