Did you know pneumatic filling machine can reduce filling time and cost? Filling bottles, containers, pouches are things of the past. With modernization, new advance techniques are emerged to skyrocket your business. Indeed, labor is essential but machine can fast your work with much accuracy and efficiency.
In this buying guideline, we are going to discuss how pneumatic filling machine can speed up your company’s production, especially food, pharmaceutical, nutraceutical, and chemicals. We will provide images to help your good understanding.

1.What is Pneumatic Filling Machine?

Pneumatic Filling MachineThese machines are employed in various wide ranging industries for instance pharmaceutical, food, cosmetic, and chemical for filling of liquid of varying viscosity.

Pneumatic filling machines are driven by compressed air rather than electric source hence are also known as air driven filling machines. They utilize vacuum pressures for instant drip free gravity based filling.

These equipment use of compressed air and are comprised for less movable parts than their electric counterparts. Pneumatic filling machines are highly accurate and precise since they fill right volume of liquids that can be adjusted according to requirement.

2.What Are The Components Of Pneumatic Filling Machine?

Pneumatic filling machines are cutting-edge innovations in which each component works as a group and in synchronicity for efficient and quick filling.

Learning about different parts of these machines assists you in troubleshooting and repairing these equipment.

Some basic parts of pneumatic filling machines are:

  • Hopper

HopperIt is the cone-shaped structure in which bulk quantity of raw materials are stored prior to the filling. From here, the raw materials or liquids go to filling station.

  • Filling station

Filling stationThis part is comprised of filling head and nozzles. The latter are used for dosing accurate quantity of liquid materials into bottles or cans. Cut-off nozzles are used for clean filling and to prevent wastage of product. The filling head goes up and down while filling.

  • Main Cylindrical Piston

Main Cylindrical PistonIt is a movable component enclosed within a cylinder. The air moves the piston which then transfers the force from compressed air to filling station.

  • Adjustable Sensor

This sensor or handle located at the top is rotated manually for quick movement of sliders which in turn leads to fast filling.

  • Gas Pressure Gauge

Gas Pressure GaugeThis gadget measures the intensity of compressed air pressure. It has is marked with scales and helps in maintaining right pressure for filling. Gas pressure gauge ascertains that there are no leakages in gas pipe.

  • Air Pressure Knob

These knobs are rotated clockwise or anticlockwise for adjusting the pressure for proper performance of pneumatic filling machines. This component is essential in maintaining the steady gas pressure by its locking mechanism.

  • Foot Switch

Foot SwitchIt is used for operating the machine manually. Pressing this component turns on the equipment. Foot switch is a safety switch used for breaking the circuit and shutting down the pneumatic filling machines.

  • Pneumatic System

 

Pneumatic SystemIt consists of compressor, air reservoir and valves. The function of compressor is to change normal air into compressed air while air reservoir stores this compressed air. The valves are employed for controlling the air pressure.

  • Operation Interface

Operation Interface

These touch screen interface is present in automatic pneumatic filling machines for easy and trouble-free programming of operational parameters. Data recipes are stored on HMI that make format change effortless and quick.

9.Pneumatic Filler VS Electric Piston Fillers

Both these equipment are types of filling machines but there are some major differences between two fillers. These differences are discussed below:

Pneumatic FillerElectric Piston Fillers
Pneumatic Filler

Electric Piston Fillers

These systems are powered by compressed air so are known as air driven fillers.These instruments are driven by electric current which move piston so these are called cam-driven piston filers.
These fillers are comprised of less number of parts hence the maintenance and cleaning of this assembly is quite easy.They have more moving parts hence cleaning and maintaining these fillers take some time.
The speed of machine is fixed during each filling cycle. Filling and return stroke is executed by same speed.Electric piston fillers can use different speed during filling operation. The speed can be adjusted either during fill stroke or on back stroke.
These are employed for filling viscous liquid materials that contain chucks or particulates. These products are filled in simple style jars.These devices are designed for filling foamy, delicate or foamy liquids that are usually loaded in long neck bottles like olive oils, chili sauce etc.
Pneumatic filler work best with flammable liquids since there is no chance of spark during filling.They are not used for filling flammable products since static charge can cause fire incidents.
