Filling classification of beverage filling machines

Beverage filling machine can be divided into normal pressure filling machine, pressure filling machine and vacuum filling machine according to filling principle; The normal pressure filling machine is filled by liquid weight under atmospheric pressure. This kind of filling machine is divided into two kinds: regular filling and constant volume filling, which is only suitable for filling low viscosity and gas-free liquids such as milk, wine, purified water, fruit juice drinks, etc. The pressure filling machine is filled at a pressure higher than atmospheric pressure, and can also be divided into two types: one is that the pressure in the liquid storage cylinder is equal to the pressure in the bottle, and the filling is carried out by the liquid self-weight flowing into the bottle, called equal pressure filling; The other is that the pressure in the liquid storage cylinder is higher than that in the bottle, and the liquid flows into the bottle by the pressure difference. This method is mostly used in high-speed production lines. Pressure filling machine is suitable for filling liquid containing gas, such as beer, soda, champagne, carbonated drinks, soda water, etc. The vacuum filling machine is filled under the pressure in the bottle lower than the atmospheric pressure; This kind of filling machine is simple in structure, high in efficiency, and has a wide range of application to the viscosity of materials, such as oils, syrup, fruit wine, etc. The specific need for what kind of filling machine, mainly according to their own beverage is what kind of beverage, with gas without gas, whether there are solid particles and so on to distinguish.
