Types of liquid filling machine

Filling machine is also known as filling equipment, filler, filling system, filling line, filler machine, filling machinery etc in the packaging industry. Filling machine is a device to fill various types of solid, liquid or semi solid products with predetermined volume and weight into container such as bottle, bag, tube, box [ plastic, metal, glass ] etc. In the packaging industries need for filling machines are very high.

Liquid Level Filling Machines

The simplest and probably one of the oldest technologies devised by man was the siphon principle. In this case we are talking about the siphon filling machine. Gravity flow into the tank to a valve that keeps the liquid level even, put some gooseneck valves up and over the tank side and back below the liquid level of the tank, start a siphon and voila, you’ve got a siphon filler. Add to that a little extra framing, and an adjustable bottle rest so you can set the fill level to the level of the tank and we now have a complete filling system that will never overfill a bottle, with no need for pumps etc. Our siphon filler comes with 5 heads (size is selectable) and can produce quite a bit more than many think possible.

Overflow Filling Equipment
In order to speed up the process of filling we have the pressure filling machine. Pressure fillers have a tank on the back of the machine with a valve to keep the tank full either by a simple float valve or by switching a pump on and off. The tank flood feeds a pump which then feeds to a manifold where a number of special overflow filling heads lower down into the bottle as the pump switches on forcing liquid into the bottles at a speedy rate. As the bottle fills to the top, and excess liquid goes back up a second port within the filling head and overflows back into the tank. At that point the pump switches off and any remaining excess liquid and pressure is relieved. Heads come up, bottles index out and repeat the process. Pressure filling machinery can be configured for semi-automatic, automatic in-line filling systems or as rotary pressure fillers for higher speeds.

Volumetric Filling Machines
Check Valve Piston Filler
Check valve piston filling machines use a check valve system that opens and closes on the infeed stroke and discharge stroke. A great feature of this type of filling equipment is that it can self prime to draw product directly from a drum or pail and then discharge into your container. Typical accuracy on a piston filler is plus or minus one-half percent. However check valve piston fillers do have certain limitations in that they cannot run viscous products or products with particulates as both can foul the valves. But if your products are free flowing (meaning they pour relatively easily) this is a great machine for startups and large producers as well.

Rotary Valve Piston Filling Machine
Rotary valve piston fillers are distinguished by the rotary valve which has a large throat opening to allow thick products and products with large particulates (up to 1/2″ diameter) from the supply hopper to flow through unimpeded. Great as a tabletop model or can be ganged for higher production requirements. Fill pastes, peanut butter, gear oil, potato salads, Italian dressing and much more on this type of piston filler with accuracy of plus or minus one-half percent. Fills accurately at a ten to one ratio of the cylinder set.
