The automatic filling machine is mainly used in the processing of fluids, pastes and viscous bodies. Let's take a brief look at these three filling methods.
1. Atmospheric pressure filling
This type of filling machine equipment generally increases the pressure by raising the storage tank. Filling is carried out by the weight of the equipment itself as power, which is more suitable for use in the processing of products with good fluidity and low viscosity.
2. Negative pressure filling
This kind of equipment is usually called a vacuum filling machine, which needs to ensure that the pressure in the bottle is lower than the atmospheric pressure, and the product is filled and filled according to the principle of air pressure balance. The design structure of this filling machine equipment is generally relatively simple, but the air tightness between the various components is relatively good.
3. Isobaric filling
This kind of equipment is mainly used for filling under the condition of higher than atmospheric pressure. One 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.
