Filler Can Equipment – Can fillers are designed to fill cans with a certain volume of liquid, paste, or other type of product. Can filling machines can be designed with different types of mechanisms to determine the proper volume of product to be filled including, piston fillers, liquid fillers, and pocket fillers. They are similar in operation to liquid and powder filler with the largest difference being that can fillers are specifically designed to handle cans while liquid and powder fillers are designed to handle glass, plastic, and other types of containers.Piston can fillers use a piston to measure out the proper volume of product to insert into the can. As the piston is drawn up, the piston draws in product from the product holding to fill the piston. Once the piston is full, a rotary drum valve, which controls the direction of inflow and discharge of product from the piston, is rotated so that as the piston compresses it will push the product out of the piston and into a can. Once the piston has emptied, the drum valve is rotated back so that as the piston is drawn up, the piston will draw product from the product hold tank. Piston can fillers can be used for liquids and pastes.Liquid can fillers are similar to liquid gravity fillers in that gravity can fillers utilize the pressure of gravity on a liquid product to fill the product into the can. Gravity can fillers plunge a nozzle into the can that has a gasket that forms a seal with the top of the can.
The nozzle on the liquid can filler then opens to allow product to flow from the product hold tank. Once the liquid reaches a level above the filling ports in the nozzle, the head pressure above the liquid in the can is equal to the pressure above the liquid in the product hold tank. Once this occurs, the liquid stops flowing into the can. As the nozzle is raised out of the can, the nozzle closes to prevent more product from entering the can.
We have introduced a new unit designed specifically for open fill of carbonated beverages. We have modified the valves and flow path diameters resulting in a much better flow with less foaming. The new filler is based on our level fill unit with a gas purge cycle and switch that initiates the flow once the can is placed on the shelf. We are estimating about 6 cans per minute with a ~10 second fill time (2 spout, so even faster with 4).
Our Carbonated Beverage Counter Pressure for Cans Filler, This Can Filling Machine has a production rate of approximately 300 12 oz cans per hour. This unique filler has the ability to counter pressure fill cans, purging the cans with CO2 prior to the fill sequence, sealing the cans against the custom stoppers. The fill is automatically stopped once the liquid (foam) reaches the level sensors. The fill process provides for a cleaner can fill, less waste and better dissolved oxygen levels for better taste and better shelf life.
