Problems solved by technology

[0006] Secondly, during the growth of ice crystals, the structure of water molecules is reorganized, which will repel the impurities in the water and accumulate in the direction perpendicular to the direction in which the ice peak advances (see Figure 11 ), forming resistance to the growth of ice crystals and slowing down the growth rate of ice crystals

Embodiment 1

[0042] Embodiment 1: see Figure 1-Figure 11 , the manufacturing method of clean transparent ice of the present embodiment, concrete steps are:

[0043] Step 1. Preparation before making ice:

[0044] Set up a supersaturated open area for displacing dissolved air in the ice-making container, specifically: a supersaturated open area is formed from the liquid level in the ice-making container to the upper opening of the ice-making container, and the supersaturated open area maintains communication with the external atmosphere to maintain supersaturation The air pressure in the open area is constant, and a heating and temperature control device is installed on the heat preservation cover to increase the external ambient temperature in the supersaturated open area and reduce the liquid surface tension; Figure 4-6 As shown, a heating and temperature control device is installed in the space of the supersaturated open area to maintain the temperature of the open area. According to...

Embodiment 2

[0053] Example 2: see figure 2 The clean and transparent ice manufacturing device of the present embodiment specifically includes an ice-making container 1, an incubator 2, a heating temperature control device 4 and a water pump 7, the ice-making container 1 is arranged in the incubator 2, and the ice-making container 1 is filled with Water, the refrigeration container is refrigerated by the evaporator or refrigerant, the liquid level of the water in the ice making container 1 forms a supersaturated open area at the upper opening of the ice making container, and the supersaturated open area is kept connected with the external atmosphere, and the top cover of the incubator 2 A heating and temperature control device 4 is arranged on the inside; a water pump 7 is arranged on the inner wall of the ice-making container 1, and the water pump 7 can be adjusted and installed on the ice-making container 1. The water pump is used to flush the crystal interface, dilute or replace the cry...

Abstract

The invention relates to a making method and a making device of clean transparent ice, and belongs to the field of ice making. The making method and the making device solve the problem that an existing ice making technology cannot discharge air dissolved in water in the freezing process. The making method and the making device are characterized in that a dissolved air supersaturated open area is arranged in an ice making container, in particular, the supersaturated open area is formed between the liquid level in the ice making container and an upper opening of the ice making container, the supersaturated open area keep to communicate with external atmosphere, and the temperature of the supersaturated open area is controlled; a mechanical disturbance mode is selected according to the volumeof the ice making container, the crystal interface is washed at a constant flow rate, the dissolved air supersaturated zone formed by the crystal interface is diluted or replaced, the temperature ofthe supersaturated open area is controlled, and the water body liquid level temperature is improved; and a clean transparent ice body is obtained by controlling the physical conditions in the icing environment. According to the making method and the making device, dissolved air and impurities in water are discharged in the icing process, and meanwhile, the ice making device which is simple in structure and convenient to use is provided for making the clean transparent ice.

Description

technical field [0001] The invention relates to an ice manufacturing method and a manufacturing device, in particular to a clean transparent ice manufacturing method and a manufacturing device, belonging to the field of ice making. Background technique [0002] Transparent ice is a kind of artificial ice. Because human intervention in the physical environment of crystal growth during the freezing process forms a clean and transparent ice body, it is called clean and transparent ice. Clean and transparent ice has no air bubbles, impurities and cracks inside the ice body, with uniform density and perfect visual effect. It is widely used in catering, entertainment, ice sculpture, gifts and other commercial fields. [0003] The existing clean and transparent ice production methods include: 1. During the ice-making process, transparent ice is obtained by injecting pressurized air into the water body; 2. Monitoring the TDS (electrolysis) value of the water body, and controlling th...
