According to the filling principle filling machine which kinds?

Liquid filling machine according to the filling principle can be divided into atmospheric pressure filling machine, pressure filling machine and vacuum filling machine. Atmospheric pressure filling machine is under atmospheric pressure filling by liquid weight. This type of filling machine is divided into two kinds of timing filling and fixed capacity filling, only suitable for filling low-viscosity liquids that do not contain gas, such as milk, wine and so on. Pressure filling machine is higher than the atmospheric pressure for filling, can also be divided into two kinds: one is the pressure in the reservoir cylinder and the bottle pressure is equal, by the weight of the liquid into the bottle and filling, known as isobaric filling; the other is the reservoir cylinder pressure is higher than the pressure in the bottle, the liquid flows into the bottle by the pressure difference, high-speed production line is used in this way. Pressure filling machine is suitable for gas-containing liquid filling, such as beer, soft drinks, champagne and so on. Vacuum filling machine is filling under the pressure in the bottle which is lower than the atmospheric pressure. This filling machine has a simple structure, high efficiency, and a wide range of viscosity of materials, such as oil, syrup, fruit wine, etc. can be applied. Oil Filling Machine It can fill all kinds of oils, such as edible oil, lubricating oil, peanut oil, soybean oil and so on. This kind of filling machine is specially developed for oil material filling filling machinery, can realize the flexible configuration of manual and unmanned operation.
