What are the differences in the three main filling methods of the filling and sealing machine

The filling and sealing machine is suitable for the production, processing, and manufacturing of products such as fluids, pastes, and thick solids. There are three specific canning methods: normal pressure, negative pressure, and pressure, which are applicable to different product standards.

1. Atmospheric pressure canning method

This type usually raises the storage tank to increase pressure. Using one's own weight as a driving force for canning, suitable for the production and processing of products with good fluidity and low viscosity, such as milk, grape wine, etc.

2. Negative pressure canning method

This type requires the pressure in the bottle to be lower than atmospheric pressure, and then based on the basic principle of air pressure balance, the product is filled and canned. This type of filling and sealing machine generally has a simple structure, but the sealing between components is good, and there is no significant standard for the thickness of materials. It can complete the production and processing of products such as syrup, oil, sauce, etc.

3. Pressure canning method

This type of canning is carried out under conditions higher than atmospheric pressure. One type uses the pressure inside the storage tank to be equal to the pressure in the bottle, and the liquid material flows into the bottle by its own weight, also known as isobaric canning. In addition, there is a type that adds a power assisted piston at the top of the storage tank to assist in completing production and processing. Common canned products include beer, champagne, carbonated beverages, etc.
