A liquid filling machine is one that fills the raw material in liquid form into bottles and vials for converting it into a final packaged product ready to be seen on the shelf and sold. A few liquid filling machines are worthwhile mentioning.
Injectable Liquid vial filling machine -This is used extensively for filling up the vials with medicines. It works on the volumetric principle with diving nozzles and a pneumatic system of stoppering rubber on top of the vials. The injectable liquid vial machine has a SS flat conveyor belt on which the vials move and get transferred. The vials are then transferred to the filling station where there are multiple heads and are in the range of two to twelve. The next station is one where a stopper is placed on the head after the precision filling. The major parts of the vial filling machine include a conveyor belt where the vials move on this belt to be transferred and a filling and stoppering machine, where the vials are filled and rubber stoppered so that there is no wastage of medicinal content and accuracy is maintained while filling the vials.
Prefilled syringe filling machine– This kind of machine is used for filling a prefilled syringe and is the aptest for use in pharmaceutical industries. Syringes are loaded on a stainless steel hopper. The pre-filled syringe tray is placed on top of the machine. Syringes move line by line to the filling station where there is an electronic pump. Once the exact volume is filled in the syringes, they move out to an outfeed tray of the prefilled syringe filling machine.
Liquid bottle filling machine– Bottles are filled up with various vicious liquids like oil used for edible purposes and commercial purposes. Bottles can be filled up using the gravimetric or volumetric option. A nozzle option is provided here for filling the bottles. If the liquid is dense or vicious pistons or pumps may be used to apply force to thicker liquids. The liquid bottle filling machine is used to even fill creams and gels. The quick-release nozzles ensure quick and faster flow.
Linear Liquid filling machine– Based on the volumetric principle the linear liquid filling machine cater to a maximum of 1000 ml bottles. The diving nozzle is used to avoid foaming and the nozzle has a suck back arrangement.
Oil filling machine– Automatic liquid filling machines often do a lot of innovations and especially where such machines are fast-moving ones. One such machine is the oil filler machine and the same concept of the line to line inward and outward feeding is used here. Here the oil can be filled in pet bottles, jars, and tins for bulk production and packaging. The automatic eight head twin-track liquid filling with rubber stoppering machine is an ultra-fast and efficient filler of liquid and has a very strong build. The Automatic Rotary piston filling and Capping machine also is a very good one with rotary valve for a drip-proof filling. The speed of such rotary can also be controlled with an AC frequency control system. Some more machines which are in demand are worth mentioning like the Volumetric Oil filling machine for a lube, Engine oil filler, Oils used for medicinal and edible purposes.
Liquid filling machine manufacturers take pride in such machines as they are flexible, versatile, and reduce wastage to zero. The machines are designed as per the need and convenience of the user and the shape and size of the containers they cater to. A Big Industry and bigger returns!
