Freshwater/seawater dual-purpose tubular ice ice maker and its ice-making process

Abstract

The invention discloses a tube ice making machine applicable to both fresh water and seawater, comprising an ice making cylinder and a refrigeration system cooling the ice making cylinder and allowing a refrigerant to flow, wherein the ice making cylinder is successively provided with, from top to bottom, a water dividing tank, a flooded evaporator and an ice discharging mechanism, the flooded evaporator is provided with a refrigerant outlet and a refrigerant inlet respectively allowing the refrigerant to exit and enter, a liquid outlet allowing the gasified refrigerant to be discharged and a heating medium inlet allowing a heating medium to enter, the water dividing tank is communicated with an external water source, the ice making cylinder is provided with a plurality of ice making pipes which penetrate the flooded evaporator and enable the water dividing tank to be communicated with the ice discharging mechanism, and the tops of the ice making pipes are provided with water distributors. Thus, prepared tube ice is more applicable to refrigeration and preservation; the problem that an ice cutter cannot work because the ice cutter is bonded by ice layers is overcome, space for the ice cutter is saved, more ice making pipes can be arranged, and more tube ice can be prepared in a same period of time. The tube ice making machine is applicable to ice making.

Description

technical field [0001] The invention relates to the field of freezing and ice making, in particular to a tubular ice making machine for both fresh water and sea water, and an ice making process of the ice making machine. Background technique [0002] The ice machine usually includes a refrigeration system and an ice-making mechanism. The existing refrigeration system includes a refrigeration system including a compressor, an oil separator, a condenser, a gas-liquid separator, a dry filter, and an expansion valve. The compressor passes through the oil separator. , condenser, dry filter, expansion valve are connected with evaporator, and evaporator is connected with compressor through gas-liquid separator to form a refrigeration cycle. [0003] The fishery industry has a huge demand for freezing and keeping fresh, especially ocean fishing vessels need to be equipped with on-board ice machines to keep the catch from spoiling. But the freezing of seawater is inversely proportio...

Problems solved by technology

Furthermore, the ice blade is formed by processing threaded grooves on the outer surface of a metal cylinder. When the refrigeration temperature is too low for a long time, flake ice will be firmly bonded to the threaded grooves without falling off, which will reduce the ice production; The remaining flakes of ice will also form a block with the ice layer in the cylinder and the skates, making the skates unable to work normally.
