What should be paid attention to in the food and beverage industry?

        The food and beverage industries are two different, but interrelated industries, both belonging to the food category. It includes all companies involved in the processing, packaging, and distribution of food ingredients, including fresh, prefabricated food, as well as packaged food, alcoholic beverages, and non-alcoholic beverages.

        With the continuous development of China's economy, the production of food and beverage industry has increased at a high rate in the past few years. In recent years, the growth of the food and beverage industry has slowed down due to the influence of macro economy. In addition, There is an imbalance between popular and unpopular items: for example, the growth rate of liquor products drops sharply, but the leisure food and convenience food segment industries will still maintain a high growth rate in the next few years.In general, despite a slowdown in China's macroeconomic growth rate, the food and beverage industry maintains a strong growth rate, which is expected to be more than 50% higher than global in the next few years.

1. Technology of the food and beverage industry

The food and beverage industry usually requires compressed air systems for processes as follows.

Pipeline transport liquid: milk, soy sauce, pure water, carbonated drinks, beer and yellow rice wine, etc.

During fermentation: stirring of liquid; Let in air to increase the oxygen content. Such as: beer, yellow rice wine, soy sauce and vinegar, etc.

Mix / stirring in the batching process: the method of sending the air flow into the liquid to stir the liquid. Generally use compressed air, sometimes also use carbon dioxide, nitrogen and other inert gas. Such as: soy sauce, vinegar,liquor blending.

Aeration in carbonated beverages:carbon dioxide is fed into a cylinder or gas holder.The carbon dioxide provided by the gas storage cabinet, when the pressure is low, it needs to be pressurized by the carbon dioxide gas compressor and sent into the mixer.

Airflow stretching: PET bottle production.

Transmission device: such as slaughtering industry.

Sterile packaging: Keep the pressure ready with sterile air.

Blow materials, blow away impurities: slaughter industry blow hair, blow broken meat, etc. Biscuit industry blow blowing powder, cleaning equipment. Correction in baking process; The wheat grains are removed by air pressure in beer filtration process.

Extruded material: in the beer industry, after the wort is cooled, sterile compressed air can push out the wort from the thin sheet cooler; filter the sugar industry, squeeze the sponge and squeeze out the sugar juice. Drive the cylinder of the filling machine, generating linear motion.

Inflatable packaging: suitable for items with low vacuum requirements and more inflation.

        These processes will use factory air, vacuum, high pressure or low pressure compressed air. Generally, this kind of compressed air is mainly used in the processing of raw materials stirring, fermentation, bagging, blowing, drying, hot air and tin injection and pneumatic exhaust and a series of production process. Compressed air must be removed from oil, sterilization and deodorization treatment, usually configuration oil-free compressed air as gas source, and then strict post-treatment of compressed air, post-treatment equipment in addition to sterilization filter, also need to configure gas liquid separator,high efficient precision filter, remove the dust in compressed air, water and oil, etc., in order to prevent pollution and accidents. To this end, the food and beverage industry is crucial for compressed air quality. Table 1 shows the most recent international standards for compressed air quality.
