Hummus does not pour. It is a thick, sticky paste that traps air, smears across the sealing area of a tub and separates slowly if the processing before it was weak. Those three facts decide which filling and sealing equipment works, and they explain why a filler chosen for sauces or juice usually disappoints on hummus.
Start with the pack, not the machine
The pack format fixes almost every other decision, so settle it first.
| Pack format | Typical use | What it asks of the equipment |
|---|---|---|
| Lidded tubs and cups | Retail shelf, deli counter | Accurate portions, a clean sealing rim, tamper evidence |
| Large tubs and pails | Foodservice, central kitchens | Large doses, fast filling, easy handling |
| Pouches and bags | Bulk catering, ingredient supply | Pump or pressure transfer, seals that hold through product residue |
| Sealed trays | Ready meals, combination packs | Film sealed over a pre-filled tray |
Filler types for a thick paste
A filler built for free-flowing liquids cannot meter hummus. You need positive displacement, which pushes out a measured amount instead of letting the product flow.
- Piston (volumetric) fillers: draw in a set volume and push it into the pack. The most common choice for pastes, and the dose is changed by adjusting the stroke.
- Pump fillers: feed from a hopper continuously, which suits higher speeds and larger containers.
- Net weight filling: doses by weight, which helps when pack weight is regulated, because the density of hummus shifts with its recipe and the air it holds.
Whatever the type, the hopper and product path should be easy to strip and clean. A paste with tahini and chickpea solids leaves residue that has to be removed between products and shifts.
Keep air out of the paste
Trapped air makes fill weights inconsistent and leaves bubbles or pockets at the surface of the sealed tub. Part of this is solved before the filler: on the industrial L120IV and L200IV, an optional vacuum system reduces air in the product. The rest is handled at the filler, by keeping the hopper at a steady level and avoiding settings that whip air back into the paste.
Sealing, coding and inspection
| Closure | Used for | Watch for |
|---|---|---|
| Heat-sealed film | Tubs, cups, trays | Product on the sealing rim causes weak seals |
| Induction seal under the lid | Tubs needing tamper evidence | A clean, flat rim and correct lid fit |
| Snap-on lid | Foodservice tubs | Often paired with a film or liner for tamper evidence |
| Pouch seal | Pouches and bags | Sealing through residue, so check seal integrity regularly |
Each pack also needs a batch code and use-by date that tie it to the batch record, and many producers add a checkweigher and a metal detector after sealing. Your HACCP plan decides which checks are required.
How the line fits together
The cutter mixer works in batches, while a filler runs continuously. A holding hopper or tank between them absorbs the difference. The usual order is:
- Cutter mixer discharge
- Holding and cooling, as set by your HACCP plan
- Filler
- Sealer
- Coding and inspection
- Cartons and palletising
Match the speeds to the rated output. On hummus the L120IV is rated at 700 kg per hour and the L200IV at 1300 kg per hour. A filler that cannot keep up leaves paste waiting in the bowl, while one far larger than the output stands idle. The wider picture of stages and bottlenecks is in our hummus production line guide, and the requirements for retail packs, shelf life and traceability are in the private label hummus guide.
Where HummusMaster fits
HummusMaster supplies the processing stage: cutter mixers from 6 L countertop models to 200 L industrial machines, made by YAZICILAR / KITPRO in stainless steel. Filling and sealing equipment is chosen to suit your pack format, and for a complete line HummusMaster can provide layout planning, installation, commissioning and operator training, so the discharge point and the filler are planned together. Send your pack format and target output with a quote request and we will tell you what fits.
Frequently Asked Questions
What type of filler works best for hummus?
A positive displacement filler. Piston fillers are the most common for thick pastes, and pump fillers suit higher speeds and larger containers. Choose by pack size, speed and how accurate the dose must be.
Can a liquid filler be used for hummus?
Not usually. Liquid fillers rely on the product flowing, while hummus is a thick paste that has to be pushed out in a measured amount.
How do I avoid air bubbles in packed hummus?
Reduce air at the source with a vacuum system on the cutter mixer (optional on the L120IV and L200IV), keep the filler hopper at a steady level, and avoid settings that whip air into the paste.
Should hummus be filled warm or cold?
Chilled hummus is normally cooled before filling, but the filling temperature and holding time are set by your HACCP plan, and shelf life is validated on your own product in its final pack.
How do I match a filler to my cutter mixer?
Compare the rated hourly output of the cutter mixer with the speed of the filler, and put a holding hopper between them. On hummus the L120IV is rated at 700 kg per hour and the L200IV at 1300 kg per hour.
