1. Atmospheric pressure filling method;

This type of equipment usually raises the storage tank to enhance pressure. Filling is powered by one’s own weight and is suitable for processing juice products such as apple juice, grape juice, etc. with good fluidity and low viscosity.

2. Negative pressure filling method;

According to industry experts engaged in the research and production of weighing juice filling machines, this type of equipment, also known as vacuum filling machines, must ensure that the pressure in the bottle is lower than atmospheric pressure, and then fill the product according to the principle of air pressure balance. This type of equipment generally has a simple structure, but the components have strong airtightness and do not have significant requirements for material viscosity. It can complete the processing of products such as honey grapefruit tea.

3. Pressure filling method;

This type of equipment is used for filling under conditions higher than atmospheric pressure. One method is to use the pressure in 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 filling. Another method is to add a booster piston at the top of the storage tank to assist in completing the machining process. Commonly found in carbonated fruit juice drinks, etc.
