A Complete Guide on How to Choose a Filling Machine and Maintenance Tips

A jug, a scoop and a scale can fill a few dozen packs a day. Past that, packs start to vary, short fills appear and someone spends the whole day on one repetitive job. A filling machine measures each dose the same way. The trick is to match the machine to the product, because a liquid filler cannot move a paste and a paste filler chokes on pieces. This guide shows how to choose and how to keep a filler accurate.

What Is a Filling Machine?

A filling machine measures a set dose of product and delivers it into a bottle, jar, pouch or container. Piston fillers push a fixed volume; peristaltic fillers squeeze liquid through a tube; powder fillers dose by set quantity; form-fill-seal machines make the pouch as well. The filling machines page lists the eight PackForge models with their rates.

Whatever the type, the operator’s job shrinks to placing and removing containers while the machine measures each dose.

Why Use a Filling Machine?

• The same dose in every pack, within the rated accuracy.
• Fewer short fills on a labelled volume.
• Less spillage and cleaner containers.
• One operator places and removes containers instead of measuring.
• Faster packing: hundreds of packs an hour even on a lever machine.

What Are the Major Types of Filling Machines?

Liquid Fillers

• LF Series pneumatic piston, 10 to 1000 ml, from ₹35,840 + ₹6,451 GST
• MLF200 peristaltic, 5 to 2000 ml, from ₹7,168 + ₹1,290 GST

Paste and Pickle Fillers

• PF Series pneumatic, 10 to 1000 ml, from ₹57,344 + ₹10,322 GST
• MPF50 lever, 5 to 50 ml, ₹13,440 + ₹2,419 GST
• 1000P for pickle with pieces, ₹1,64,864 + ₹29,676 GST

Powder and Pouch Machines

• PGF200 / 999 powder and granule fillers, from ₹22,041 + ₹3,967 GST
• GF100 granule sachet FFS, from ₹87,360 + ₹15,725 GST
• LP1000 liquid pouch packer, ₹1,15,000 + ₹20,700 GST

Understanding Dose Range, Accuracy and Speed

Dose range is the smallest and largest fill a model handles; pick the model whose range centres on the pack you sell most. Accuracy is quoted as a share of the dose (up to 1% on the LF, PF and 1000P, about ±2% on the MLF200) or in grams (±1 g on the PGF200, ±3 g on the PGF999). Speed appears as fills a minute, bottles an hour or bags a minute. Drive – lever, electric or compressed air at 0.4 to 0.6 MPa – decides what you need on site.

A useful habit: when a model’s range spans two of your packs, buy for the pack that sells most, and check the dose on a scale each time you change over.

Filling Machine Features to Look For

Product contact parts that strip down for cleaning.

An agitated hopper where solids and oil separate, as on the 1000P.

No wetted parts for many small products, as with the MLF200 tube.

A suction pipe from the drum instead of a hopper, on the LF Series.

Power-free operation where supply is unreliable, as on the MPF50.

Film-fed pouch making once volumes justify it, on the GF100 and LP1000.

How to Choose the Right Filling Machine?

1. Test the flow: does the product pour, ooze, carry pieces or run as powder?
2. List pack sizes and pick for the best seller.
3. Check the site: compressed air, power and bench space.
4. Count packs per hour and plan for next year’s volume.

For example, a sanitiser maker filling 100 ml bottles would look at the LF100 or MLF200; a ghee packer filling litre jars at the PF1000; a pickle unit at the 1000P; a tea packer at the PGF200; a dairy moving to milk pouches at the LP1000.

Common Filling Problems

Foaming liquids: sanitisers and cleaners foam, which changes the nozzle and the speed – mention it before ordering.

Pieces jamming: pickle needs a wide-bore piston; measure the largest piece and the jar mouth.

Powder bridging: some masalas bridge in a hopper, which changes the recommendation.

Weight not matching the label: a volume filler cannot guarantee net weight; add a checkweigher where weight is the legal basis.

Filling Machine Buying Checklist

• The product: a sample, its thickness at filling temperature, pieces and their largest size, and whether it foams or bridges.
• The packs: every dose you sell, the container or pouch, and the mouth size.
• The count: packs per hour now and next year.
• The site: compressed air at 0.4 to 0.6 MPa, power, bench space and floor.
• The rule: whether the label states volume or weight, and the tolerance you must meet.

Send the list with a product sample and you get a recommendation based on the product, not the brochure.

Where the Filler Sits on a Line

Filling is the first step of a short line. After it, bottles and jars are capped – by hand or on a capping machine – often given an induction foil seal, then labelled on a labelling machine. Pouches filled on a PGF powder filler are closed on a band or impulse sealer. The GF100 and LP1000 do it all in one machine: they form the pouch from film, fill it and seal it. Plan the whole line together so one slow step does not waste the speed of the others.

Quick Examples by Product

• Hair oil and sanitiser in 100 ml bottles: LF100, or the MLF200 for many small lots.
• Edible oil in 500 ml or 1 litre bottles: LF500 or LF1000.
• Ghee in half and one litre jars: PF1000.
• Face cream and balms in 50 g jars: PF100, or the MPF50 without power.
• Mango or lime pickle with pieces: 1000P.
• Tea, masala and coffee up to 200 g: PGF200; sugar and detergent up to 999 g: PGF999.
• Mukhwas and supari sachets: GF100.
• Milk and buttermilk pouches: LP1000.

How to Maintain a Filling Machine?

At every product change: empty and clean the hopper, piston and nozzle.

End of shift: do not leave spiced oil or ghee standing in the machine overnight.

Pneumatic models: keep air dry and at 0.4 to 0.6 MPa.

MLF200: flush or change the tube between products.

Check the dose on a scale at the start of each run.
