Keyuan filling machine: common filling methods of filling machines

Do you know the five common filling methods of filling machines? The following filling machine manufacturers will introduce you in detail: Atmospheric pressure method: Atmospheric pressure method is also called pure gravity method, that is, under normal pressure, the liquid material flows into the packaging container by its own weight
.

Most non-gas-liquid materials that can move freely can be filled in this way, such as milk, soy sauce, vinegar,
etc.

Isobaric method: Isobaric method, also known as pressure gravity filling method, is to first inflate the packaging container under the condition of higher than atmospheric pressure to make it form the same air pressure as that in the liquid storage tank, and then flow into the packaging container by its own weight.
inside
.

This method is commonly used in the filling of carbonated beverages, such as beer, soft drinks, sparkling wine,
etc.

Filling in this way can reduce the CO contained in such products and avoid excessive foaming during the filling process, which affects product quality and quantitative accuracy
.

Pressure method: Use mechanical pressure or air pressure to squeeze the material to be filled into the packaging container.
This method is mainly used for filling thick materials with high viscosity, such as filling ketchup, minced meat, toothpaste, etc.
In the filling of soft drinks, the air pressure of the soft drink is directly poured into the uninflated and isobaric bottle, thereby increasing the filling speed, and the resulting foam has a corresponding impact on the quality of the soft drink without glue
.

 　　Vacuum method: The vacuum method is filled under the condition of lower than atmospheric pressure, which can be carried out in two ways: (a) Differential pressure vacuum type, that is, the liquid storage tank is at normal pressure, and only the packaging container is pumped to make it To form a vacuum, the liquid material relies on the pressure difference between the liquid storage tank and the container to be filled to generate flow to complete this method
.

 　　(b) Gravity vacuum type, that is, the liquid storage tank is in a vacuum, the packaging container is first evacuated to form a vacuum equal to the liquid storage tank, and then the liquid material flows into the packaging container by its own weight, which is rarely used in China
.

Vacuum filling has a wide range of applications, and it is suitable for filling liquid materials with slightly higher viscosity, such as oils, syrups,
etc.

It is also suitable for filling liquid materials, such as, etc.
The formation of a vacuum in the bottle means that the contact between the liquid material and the air is reduced, and the shelf life of the product is prolonged
.

 　　Using mechanical pressure or air pressure, the material to be filled is squeezed into the packaging container.
This method is mainly used for filling thick materials with high viscosity, such as filling ketchup, minced meat, and toothpaste.
It can also be used for filling soft drinks such as soft drinks.
At this time, the air pressure of the soda water itself is directly poured into the uninflated isobaric bottle, thereby increasing the filling speed, and the formed foam has a corresponding impact on the filling quality due to the absence of the soda water
.
