Many processing processes in the food industry are optimized using vacuum systems. In the process of food packaging, vacuum pumps can be used to expel air, can extend the storage time of food, and can remove odor. The application of vacuum pump in food industry: sublimation, drying, dehydration, vacuum evaporation, degasification, deodorization, sterilization, vacuum preservation, vacuum packaging, etc. Many processing processes in the food industry can be optimized by using vacuum systems. In addition, in the packaging process of food, the vacuum pump can be used to discharge air, can extend the storage time of food, and can remove odor.

Degassing of mineral water

Natural water mineral water contains carbonic acid, minerals and iron. If it comes into contact with air, the iron dissolved in water will oxidize, making the water taste bad. The water needs to be treated with iron at a pressure of about 50mbar, but the carbides in the water are first removed by a vacuum pump and then introduced to produce soda water.

Tea and condiments kill bacteria

Tea and condiments imported from the tropics are placed in containers and then shipped, often with pests, insects, fungi, and bacteria that must be killed first if further processing is required, achieved by placing the containers in vacuums and evacuating the air. Then, steam or germicidal gas is injected into the container.

Sausage production

To produce sausages, the mixed meat is cut into small pieces and seasonings and additives are added. Evacuation of air during cutting and mixing avoids oxidation of the mixed meat, which can affect the taste and appearance of the sausage. A vacuum device was used to evacuate the air at a pressure of approximately 100mbar. The vacuum pump used is not sensitive to the meat and particles pumped out at the same time.

Production of ham

It's hard to see ham dry and smoked on a real mantelpiece. Instead, the ham is made by soaking, which allows the meat to be soaked faster and more directly after the air is evacuated.

Humidity of tobacco products

  Without proper humidification, tobacco products packaged in boxes are too fragile and can break into fine pieces during further processing. A vacuum pump was used to evacuate the air in the box and steam and sometimes aromatics were added.

Vacuum evaporator

A vacuum pump can be used to assist in the evaporation of the liquid material in the mixture. The evaporator is usually a packed tower. According to the actual environmental conditions, the vacuum pump material can be selected from standard materials or stainless steel. Vacuum evaporator can be used in many occasions, such as milk evaporator in milk processing plant, concentrated liquid evaporator in pulp plant, crystallization device in chemical plant and tower evaporator in sugar plant.
