The dosing devices for liquids are independent devices, which are normally mounted to the packaging machines and work together with them. The main function of the dosing device is the separating of the product into predefined doses, which are set by the machine operator. The ready doses are then fed to the packaging machines.
Working method of the dosing devices for liquids:
The dosing devices for liquids are a variety of the volumetric dosing devices, where the dosage is done via the help of a piston. Generally, the dosing device consists of 3 main parts - intake bunker, valve box and a piston. The process of dosing runs in the following consequence:
1. Loading the piston with product
2. Dosing the loaded volume of product
This operation is mediated by the valve box (distributor), which switches from a mode for loading the piston to a mode for dosing the loaded volume of product. The volume of the dose can be regulated by changing the pace of the piston.
