The filling machine has a simple structure, high efficiency, and wide adaptability to the viscosity of oil, syrup, fruit wine, and other materials. According to the filling principle, it can be divided into the atmospheric filling machine, pressure filling machine, and vacuum filling machine.
Atmospheric filling machine:
Filling with liquid’s weight under normal pressure. This filling machine can be divided into the conventional filling and constant volume filling. It is only suitable for filling low-viscosity airless liquids, such as milk, wine, etc.
Pressure filling machine:
Used for filling when the pressure is higher than atmospheric pressure. It can be divided into two types: one is the pressure in the liquid storage cylinder is equal to the pressure in the bottle, and the liquid flows into the bottle according to its weight, which is called equal pressure filling; the other is that the pressure in the liquid storage cylinder is higher than the pressure in the bottle. Liquid enters the bottle through the pressure difference and is often used in high-speed production lines. The pressure filling machine is suitable for filling gaseous liquids such as beer, soda, and champagne.
Vacuum filling machine:
Used for filling when the pressure in the bottle is lower than atmospheric pressure. The filling machine has a simple structure and high efficiency and is suitable for the viscosity determination of oil, syrup, fruit wine, and other materials.
Oil filling machine:
It can fill various oils such as edible oil, lubricating oil, peanut oil, soybean oil, etc. It is a filling machine specially developed for oil filling, which can realize the flexibility of manual operation and unmanned operation.
Plug filling machine:
This type of filling machine is widely used in special industries such as medicine, food, daily chemical, petroleum, and agriculture. It can be filled with various liquids and paste products, such as disinfectants, hand sanitizers, toothpaste, ointments, cosmetics, etc.
