Vacuum pump is a large quantity and wide range of products, directly affecting the performance and quality of vacuum complete sets of equipment.The market for vacuum pumps changes dynamically according to the needs of users, and the application of vacuum pumps is becoming more and more widespread, and the speed of its market development can be described as changing day by day, and it changes dynamically according to the changes in user needs almost every moment.

Many processes in the food industry are optimized by vacuum systems.Vacuum pumps can be used to expel air during the food packaging process, which can extend the storage time of food products and remove odour.

Vacuum pumps in the food industry: sublimation, drying, dehydration, vacuum evaporation, degassing, deodorization, sterilisation, vacuum preservation, vacuum packaging and so on.

Many processes in the food industry can be optimized by using vacuum systems.

In addition, vacuum pumps can be used to expel air during the packaging of food, which can extend the storage time of food and remove odour. Below we give examples of specific application scenarios for vacuum technology.

l Mineral water degassing

Mineral water from natural sources contains carbonic acid, minerals and iron.If exposed to air, the iron dissolved in the water will oxidise and make the water taste bad.

The water needs to be de-ironed at a pressure of about 50 mbar, although first a vacuum pump is used to remove the carbide from the water before it is introduced and used to produce soda.

l Deodorisation of salad oils and fats

Prolonged exposure can cause odour to develop in salad oils and fats.Before they can be further treated, the oxides must be removed.This can be achieved by injecting steam, which absorbs odour, and then using vacuum equipment to remove the steam.

l Tea and spices

Tea and spices imported from the tropics are placed in containers and then loaded onto ships, often carrying pests, insects, fungi and bacteria that must first be sterilised if they are to be further processed, which is achieved by placing the container in a vacuum vessel and evacuating the air.The container is then filled with steam or sterilising gas.

l Sausage production

To produce sausages, the meat mixture is cut into small pieces and seasonings and additives are added.Evacuating air during the cutting and mixing process prevents the mixed meat from being oxidised, which would affect the flavour and appearance of the sausage.A vacuum unit is employed to evacuate the air at a pressure of about 100 mbar.The vacuum pump employed is insensitive to the meat and particles pumped together.

l Ham production

You'd be hard pressed to see a ham dried and smoked over a real fireplace.Instead, hams are made by immersion, which allows for a quicker and more immediate soaking of the meat after the air has been evacuated.

l Tobacco products humidification

Without proper humidification, tobacco products packaged in cartons are too fragile and can be broken down to a fine powder during further processing.A vacuum pump is used to evacuate the air from the box, and steam and sometimes aromatics are added.

l Vacuum evaporator

Vacuum pumps can be used to assist the evaporation of liquid substances from a mixture.The evaporator is usually a packed tower, according to the actual use of environmental conditions, the vacuum pump material can be selected from standard materials, can also choose stainless steel.Vacuum evaporator can be used in many occasions, such as milk processing plant in the milk evaporator, pulp plant thick liquid evaporator, chemical plant crystallisation device and sugar factory tower plate evaporator.
