A nitrogen generator for the food industry is a kind of equipment used to produce and package food, and its working principle is to remove oxygen from the air, so that the packaged food is in a low-oxygen environment, so as to extend its freshness life. The following is a detailed introduction to the working principle and application of food nitrogen machine.
1.How the food industry actively works with a single order:
The food nitrogen machine is mainly composed of a compressed air system, a separation membrane module and a control system. The workflow is as follows:
Compressed air system: First, the outside air is filtered and purified and then entered into the compressor for compression.
Separation membrane module: After compression, the air enters the separation membrane module, and in this process, the dry and pure, a large amount of stable, reliable, high-quality, high-purity N2 (99.) containing high concentration, pure water, oil, dust, dust-free particles, small and light mass is separated through selective osmosis technology9%）。
Control system: Finally, the control system is used to regulate and monitor the generated pure and dry N2 and deliver it to the place where the N2 needs to be used.
2.Application of nitrogen generator in food industry:
Food preservation: Food nitrogen machine is mainly used in the food industry, which can extract the air in the packaging bag and inject pure dry N2, thereby reducing the oxygen content inside the packaging bag. Doing so can effectively extend the shelf life of food, prevent the growth of bacteria and mold, and maintain the original fresh taste of food.
Food processing: In some special cases, when certain ingredients need to be processed or preserved, the use of food nitrogen machine can play a good role. For example, in wine production, the amount of carbon dioxide produced during fermentation can be controlled by injecting the right amount of N2 into the fermenter;During the roasting process of coffee beans, it can be used to remove excess moisture and odors from the surface of the coffee beans.
Pharmaceutical field: It also has certain applications in the pharmaceutical field. For example, in the manufacture of pharmaceutical powders, in order to avoid problems such as moisture and deterioration affecting the quality, stability and effectiveness of the drug, a food nitrogen machine is usually used to provide a dry environment.
3.Summary:
From the above introduction, it can be known that the working principle of nitrogen generators in the food industry is to provide pure and dry N2 by separating oxygen in the air, so as to extend the shelf life of food and improve product quality. It is used in a wide range of applications, including food preservation, food processing, and medicine. With the continuous improvement of people's requirements for food safety and quality, food nitrogen machine will have a broader development prospect in the future.
