Food carbon dioxide recovery device

This recovery device consists of defoaming, water washing, air storage bag, compression, adsorption, drying, refrigeration, storage tank, vaporization and filling units. It is used to recover the carbon dioxide produced during beer or alcohol fermentation and purify it for use. Use, the specific process flow is as follows:
The carbon dioxide gas produced during the fermentation process is first washed away by the demister and then flows to the water washing tower. The water washing tower and potassium washing tower are filled with packing and equipped with a circulation system.
The 1# water washing tower can recover the alcohol in the CO2 gas and wash away the water-soluble impurities. The potassium scrubber can utilize the strong oxidizing property of potassium permanganate to oxidize organic impurities in CO2 gas.
2 # Water washing tower recovers the remaining part of CO2 gas. The carbon dioxide gas is compressed to 1.6-2.0Mpa with the help of a two-stage carbon dioxide oil-free lubrication compressor and then sent to the adsorption tower. In order to ensure the stable operation of the carbon dioxide compressor, an air bag is installed between the water washing tower and the carbon dioxide compressor. The compressed gas is purified by the adsorption tower and drying tower, and the purified carbon dioxide gas is condensed into a -18° liquid in the carbon dioxide condenser; the cold source of the condenser is provided by the refrigeration unit. Liquid carbon dioxide enters the tank and survives. When the user needs to use gas, the liquid carbon dioxide is heated by the vaporizer at a constant pressure, turns into gaseous carbon dioxide, and is then reduced to the pressure required by the user through the pressure reducing valve for use. If canning is required, fill the liquid carbon dioxide in the storage tank into the cylinder through the canning pump.

In our daily lives, carbon dioxide is a colorless, odorless and imperceptible gas, but it is an important part of our surrounding environment. In many fields such as industry, agriculture, energy, and environmental protection, carbon dioxide plays an irreplaceable role. Especially in the food industry, the application of carbon dioxide is even more extensive and important. Therefore, the application of food carbon dioxide recovery devices is attracting more and more attention.

Food carbon dioxide recovery device is a device used to recover carbon dioxide generated during food processing. Through this equipment, carbon dioxide produced during food processing can be collected, purified, compressed and liquefied, thereby realizing the reuse of carbon dioxide. This recycling device has broad application prospects in the food processing industry.

First of all, carbon dioxide is an important protective gas during food processing. In fields such as fruit and vegetable preservation and meat refrigeration, carbon dioxide can effectively inhibit the growth and reproduction of microorganisms, thereby extending the shelf life of food. At the same time, carbon dioxide can also be used for gas exchange during food packaging and transportation to maintain the freshness and taste of food.

Secondly, carbon dioxide can also be used for cleaning and disinfection during food processing. In the food production line, cleaning and disinfection of machinery and equipment are essential links. The use of carbon dioxide cleaning agents for cleaning and disinfection can not only remove residual dirt and bacteria, but also avoid secondary pollution caused by the use of chemicals.

In addition, carbon dioxide can also be used to make beverages and food additives. In drinks such as carbonated drinks and beer, carbon dioxide can increase taste and refreshment. At the same time, carbon dioxide can also be used to make food additives, such as edible dry ice.

In summary, the application of food carbon dioxide recovery devices is of great significance to the development of the food processing industry. By recycling and reusing carbon dioxide, we can not only reduce environmental pollution, but also achieve efficient use of resources. In the future, as people pay more and more attention to environmental protection and resource utilization, the application of food carbon dioxide recovery devices will become more and more widespread.
