Novel tube ice machine

Abstract

The invention relates to a novel tube ice machine. The novel tube ice machine comprises a refrigerating system and a tube ice bucket. A refrigerant compressed and condensed by the refrigerating systemis changed into a liquid state, after being throttled, the liquid state refrigerant flows into the tube ice bucket through a liquid inlet tube of the tube ice bucket to be evaporated, heat of water flowing along the outer wall of a heat exchange tube of the tube ice bucket is absorbed, the temperature of the water is lowered, the water is frozen along the tubular outer wall of the tube ice bucket, and ice making is completed; then the condensed gaseous refrigerant which is not completely liquefied is driven to flow into the tube ice bucket to exchange heat with the made ice, ice removing is conducted, ice making and ice removing operation is conducted repeatedly and alternately, and finally tube ice making is completed; and an intelligent valve is further arranged, an outlet communicateswith the liquid inlet tube of the tube ice bucket, an inlet communicates with a throttled refrigerant channel, through the intelligent valve, bidirectional flowing of the liquid refrigerant can be achieved, and the gaseous refrigerant in the tube ice bucket is blocked and flows reversely through the intelligent valve. According to the technical scheme, the intelligent valve controls one-way flowing of the gaseous refrigerant and bidirectional flowing of the liquid refrigerant, the system and control are simplified, and operation is reliable.

Description

technical field [0001] The invention relates to the field of refrigeration, in particular to a novel tube ice machine. Background technique [0002] Tube ice machine is a kind of ice machine. It is named because the shape of the ice cubes produced is a hollow tube with irregular length. The cylindrical hollow tubular ice with an inner hole of 5-15mm and a length between 25mm-42mm has a variety of sizes to choose from. The outer diameters are: 22, 29, 32, 35mm, etc. The hollow tubular ice cubes produced are called tube ice, the contact area is the smallest among the existing ice types in the market, and the resistance to melting is the best. It is suitable for drinking preparations, decorations, Food is kept fresh in ice, etc., so most of them are edible ice. [0003] In use, the common way is to use the refrigeration system to make tube ice, that is, through the evaporation of the refrigerant, absorb the heat of the water flowing along the inner tube wall, so that the wate...

Problems solved by technology

[0003] In use, the common way is to use the refrigeration system to make tube ice, that is, through the evaporation of the refrigerant, absorb the heat of the water flowing along the inner tube wall, so that the water freezes along the inner tube wall, and then pass through the high-temperature refrigerant gaseous state, Melt ice along the inner tube wall, de-ice, and finally complete the production of tube ice. Since the refrigeration system is in operation, frequent ice production, melting and de-icing are required. The high and low temperature refrigerants of the refrigeration system need to be in the tube ice evaporator Alternate flow back and forth, the pipeline system used is relatively complex, and the evaporation pressure of the refrigerant is unstable, resulting in poor reliability and prone to failure when the refrigeration system is running, which affects the normal ice making defects
