Automatic filling machine is mainly a small product in the packaging machine. It can be divided into liquid filling machines, paste filling machines, powder filling machines, granule filling machines, semi-automatic filling machines and fully automatic filling lines, in terms of production automation. In recent years, with the QS certification of food products, edible oil producers have started to focus on product quality and packaging, hence the prominence of filling machines among filling machines.

　　According to the filling principle, filling machines can be divided into atmospheric filling machines, pressure filling machines, liquid filling machines, filling machines, paste filling machines, cream filling machines, granule filling machines, powder filling machines, vats and buckets. Diamond-shaped machines and vacuum filling machines.

　　The process of liquid filling machines is generally as follows: empty bottle cases are stacked on a pallet, the conveyor belt is sent out to the unloading pallet machine, the pallet is unloaded, the case is sent out to the unloading machine with a conveyor belt, the empty bottles are removed from the case, the empty case is sent through the conveyor belt to the washing machine, then cleaned and transported to the packaging machine so that the container is transported. Bottles are filled with drinks. The empty bottles from the unloader are sent to the bottle washing machine where they are sterilised and cleaned on a separate conveyor belt. The bottles are inspected by the bottle inspection machine and then enter the washing and sealing machine where they are cleaned to meet the cleaning standards. The drinks are filled into the bottles by the filling machine. The bottles are sealed and transferred to the labelling machine, to the packaging machine, then to the packaging machine and then to the pallet to place the pallets.
