[Chinese Packaging Network] Today’s title is because a customer from Zhongshan had called Xiaobian to ask for a nitrogen generator in the previous few days. Because he was a food industry, he asked some food preservation and nitrogen production parameters, etc. Xiaobian writes out these parameters and so on.
Product Name: Food Nitrogen Generator
Product features: Traditional food packaging preservation, generally choose to add preservatives or vacuum, but neither method can better extend the freshness and quality of food. Our company has specially developed food nitrogen equipment for food preservation, which is specially used for food preservation, food packaging, and food gas conditioning. Before food packaging, it is filled with sterilized high purity, high Clean nitrogen, so that there is almost no oxygen inside the packaging, so as to prevent oxidation of food, deterioration. This prolongs the freshness and shelf life of foods, and it is based on the physical method of nitrogen filling, which will not harm the human body. This technology has been widely used in foreign countries. Some high-end food manufacturers in China have already put into use. Most of the domestic The food company has done a complete rectification in terms of packaging and preservation. After the nitrogen produced by the food nitrogen generator passes through the sterilizing filter, the cleanliness of nitrogen is very high and has attracted the attention of the food industry.
What are the precautions for nitrogen filling and nitrogen making in the food preservation industry?
1, according to the use of gas pressure and the use of gas flow meter after the production of nitrogen valve, do not arbitrarily adjust the flow to ensure the normal operation of the equipment;
2, nitrogen gas valve opening should not be too large to ensure the best purity;
3, nitrogen analyzer flow meter should be adjusted to 0.5L / h scale;
4. Do not turn the valve that is adjusted by the commissioning personnel so as not to affect the purity;
5, Do not arbitrarily control the electrical devices in the cabinet, do not arbitrarily open the pneumatic pipe valves;
6. The operator should regularly inspect the pressure gauge on the nitrogen generator and make a daily record of the pressure change to prepare for equipment failure analysis;
7. Observe the outlet pressure, flow meter indication and nitrogen gas purity regularly, compare it with the required value, and find that the problem is solved in time;
8, in accordance with the air compressor, dryer, filter, technical requirements of maintenance and maintenance to ensure air quality (air source must be free of oil). Air compressors and dryers must be repaired at least once a year. Replace the wearing parts according to the equipment maintenance and service regulations and perform maintenance.
9. During the working process of air separation and nitrogen making equipment, the carbon molecular sieve has some wear and it is necessary to inspect and fill the molecular sieve once a year.
10. Complete the daily record form.
