Classification and Application of Filling Machines

filling machine

Filling machines are packaging machines that load precise quantities of packaged products into various containers. From the perspective of material packaging, it can be divided into liquid filling machine, paste filling machine, powder filling machine, particle filling machine; in terms of the degree of automation of production, it can be divided into semi-automatic filling machine and automatic filling production line.

Granule filling machine

The working principle of the granule filling machine:

Granular slurry filling machine is a product that is transformed and innovatively designed on the basis of advanced filling machine technology. It has a simple structure, high precision and easier operation. The filling head adopts the anti-drawing and lifting filling device. The filling valve is controlled by a pneumatic valve, and the filling accuracy is higher. The filling volume and filling speed can be adjusted arbitrarily.

Application of granule filling machine:

Granule filling machine is suitable for small bag packaging of medicine, food, chemical industry, pesticide and so on. It is suitable for the production of granular drugs, sugar, coffee, fruit, tea, monosodium glutamate, salt, seeds, desiccant and other fine particle manufacturers.

Liquid Filling Machine

The working principle of liquid filling machine:

According to the different filling pressure, the liquid filling machine is divided into: normal pressure liquid filling machine, vacuum liquid filling machine and pressure liquid filling machine.

①Atmospheric pressure liquid filling machine performs self-flow filling according to the weight of the liquid. This type of filling machine has greater requirements on the viscosity and gas content of the liquid. According to the filling mode, it is divided into timed filling and constant volume. filling.

②The vacuum filling machine fills the bottle when the pressure in the bottle is lower than the atmospheric pressure. This filling machine has a simple structure and high efficiency, and is generally used for liquids with high viscosity.

③Pressure filling machine refers to filling under the condition of higher than normal pressure. It can also be divided into two types: one is that the pressure in the liquid storage tank is equal to the pressure in the bottle, and the filling is carried out by the liquid flowing into the bottle by its own weight. It is called isobaric filling; the other is that the pressure in the liquid storage tank is higher than the pressure in the bottle, and the liquid flows into the bottle by the pressure difference. this method.

Application of liquid filling machine:

The liquid filling machine is mainly used for liquid filling of lotion, nursing liquid, oral liquid, disinfectant, eye wash, nutrient solution, wine, injection, pesticide, medicine, perfume, edible oil, lubricating oil and special industries.

Gas filling machine:

The working principle of the gas filling machine:

The working principle of the gas filling machine is relatively simple. It directly relies on the booster pump to fill the gas to be filled, which is similar to the pressure liquid filling machine.

Commonly used gas filling objects are: natural gas, coal gas, nitrogen, carbon dioxide, etc. The gas filling machine has high requirements on the working environment, and generally requires filling in a working area with ventilation, low temperature and no open flame.

Application of gas filling machine

Gas filling machines are widely used in the filling and production of various gas products, such as pure oxygen, fresh air, cassette gas, etc.
