The application of flake ice machine in concrete cooling/chemical dyestuff

2022-01-25

Theflake ice machine is used in large-scale hydropower dams, nuclear power, high-speed railways, and high-rise building foundations. Large-volume pouring requires temperature-controlled concrete. During the curing process of concrete, the heat of hydration increases the temperature of the concrete by 25°C, resulting in an increase in the volume of the concrete. After curing, the temperature of the concrete decreases and the volume decreases, which usually causes cracks in the dam. Therefore, the initial pouring temperature of concrete should control the corresponding concrete discharge temperature according to different concrete grades, so as to ensure that the maximum temperature of concrete during curing cannot exceed the limit temperature of the design unit.

 

In the construction of large dams and high-rise building foundations, the use of temperature-controlled concrete is required for the pouring of large volumes. Different countries and different construction sites have different requirements for concrete pouring temperature, ranging from 7°C to a maximum of 30°C. But every project requires a well-configured concrete refrigeration system. Among them, the flake ice produced by the flake ice machine is the most effective pre-cooling method. Every 10kg of flake ice can reduce the temperature of one cubic meter of concrete by about 1.2°C to 1.4°C.

During the curing process of concrete, with the release of hydration heat, the internal strength of concrete gradually increases. This phenomenon is not important for small concrete structures, but it is of special significance for dam projects that require a large amount of concrete.

Similarly, in the development of chemical and dye industries, flake ice is indispensable. The flake ice machine produced by CBFI can solve the heat generated by chemical reaction and coupling reaction in the process of chemical industry, dye production and processing, avoid other adverse reactions and produce high-quality chemical raw materials and dyes.

Other applications of flake ice machine:

1. Application of flake ice machine in food processing industry

CBFI flake ice machine is widely used in the food processing industry. After the food is sterilized at high temperature, it is quickly cooled by mixing ice water to avoid bacterial growth and maintain the original flavor of the product; during the rolling and rolling process of sausage production, due to the high-speed rotating rolling The high temperature generated by the friction between the kneading barrel and the ingredients not only promotes the growth of bacteria, but also changes the color and taste of the meat, and will cause defatting (melting of fat) to make the produced sausage bacteria exceed the standard, the color is dull, the taste is hard, and greasy. When flake ice is mixed into sausage ingredients, it achieves rapid cooling and ideal consistency, maintaining product color and taste, preventing skim and improving hygiene standards.

2. Application of flake ice machine in slaughtering industry

With the continuous improvement of people's living standards, the hygiene requirements for food hygiene are becoming more and more strict. Especially for food export processing enterprises, every production process and process has very strict requirements. In terms of poultry slaughtering, according to the relevant regulations of the Ministry of Health of the People's Republic of China, the water temperature in the spiral pre-cooling tank needs to be controlled at 0℃-4℃. It is also necessary to add a large amount of flake ice to the spiral pre-cooling tank to control the water temperature

3. Application of flake ice machine in marine fishery

The CBFI sea water flake ice machine is made of stainless steel, anti-corrosion aluminum alloy and alloy with special surface treatment. Significant savings. Our flake ice equipment is tilted within 35 degrees to keep the water circulating without spilling and in normal use. Small footprint, low noise, energy saving and environmental protection.
