Filling machine is suitable for packing all kinds of liquid, paste and powder. It is a kind of automatic packaging machine used in batch production. The main function of the filling machine is to fill the packaging material into a certain container or bag accurately and quickly.
There are different types of filling machines commonly used for different application, including piston fillers, gravity fillers, atmospheric fillers, Net Weigh Fillers, Timed flow volumetric fillers and more.
Piston fillers are the most common type of filling machine. It utilizes a piston mechanism to deliver accurate volumetric volumes at a controlled rate. In combination with the reciprocating cycle and filling nozzle, the piston fillers can steadily and quickly transport the products and complete the packaging process. It is suitable for filling paste, cream and other products with high viscosity.
Gravity Filler is a good choice for products that flow easily by gravity, such as water, beer, and juice, while avoiding overflow and waste. It consists of a hopper, a filling cylinder and a filling nozzle. When the product is put into the hopper, the product enters the cylinder and spills out from the nozzle through a valve-controlled opening.
Atmospheric Fillers are mainly used to fill volatile materials, such as liquid petroleum gas and solvents with a vapor pressure of 64 psig or less. Due to the precise filling valve and precise pressure measuring device, the gas tight filling is complete, and the high temperature ultra-low temperature product is good.
Net Weigh Fillers are mainly used to fill high-precision quantitative packaging, especially powder and granule products, such as cooking powder, feed, seed, salt, etc. They to weigh each batch of products accurately and fill them into the package.
Timed Flow Volumetric Filler can acheive high precision in measuring and filling product. It can pump the product into the package and stop automatically depending on the preset time, hence achieving good consistency and accuracy.
In conclusion, the filling machines have many advantages, such as high productivity, flexibility, accuracy and repeatability. It had been widely used in different industries like food and beverage, pharmaceutical, cosmetic, chemical, dairy and so on. The types of filling machines are different, so customers can choose an appropriate machine according to their production requirement. As long as the filling technology and parameters are selected correctly, the machine can work successfully and help to improve efficiency.
