DOZE400TB commercial vacuum sealer 400 mm – 20m³/h

DOZE400TB tabletop chamber vacuum sealer

DOZE400TB is a tabletop chamber vacuum sealer with two sealing bars. Two bags are laid in the chamber side by side and both are sealed in the same cycle, so the machine packs twice as much per cycle as a single-bar model of the same size.

The chamber measures 440 × 420 × 75 mm, deep enough for products a 50 mm chamber will not take, and each bar seals a bag mouth up to 400 mm wide. The 20 m³/h pump empties that chamber quickly, so the cycle stays short even at full depth.

Vacuum, sealing and cooling times are set on the panel and stored in ten programs P0–P9. The vacuum time runs from 0 to 99 s and the sealing and cooling times from 0 to 9.9 s, which is what keeps every bag the same.

It is still a bench machine: about 560 × 500 × 460 mm and 70 kg on a 220 V socket, with a stainless steel chamber and a transparent lid.

DOZE400TB in production and packaging lines

The DOZE400TB tabletop chamber vacuum sealer is used in food processing, pharmaceuticals, electronics, and chemical industries where airtight packaging is required to preserve product integrity. It fits on a worktable or bench and can be integrated into small-scale production lines or used as a standalone unit for batch packaging.

Typical applications include vacuum packing of meats, cheeses, ready meals, sauces, powders, seeds, and electronic components. The double bar design is suited for operations needing to seal two bags per cycle, such as portioning food products or preparing kits of small parts.

Technical specifications

What the double bar and the 20 m³/h pump give you

• Two bags per cycle. Two sealing bars of 400 mm work at the same time, so the output is double without a second machine.
• A 75 mm chamber. Deeper than the 50 mm of the smaller models. Blocks, trays and filled bags that will not lie flat elsewhere fit in here.
• A 20 m³/h pump. Twice the capacity of the 300 model, so a bigger chamber does not mean a longer cycle.
• Ten programs. P0 to P9, each with its own vacuum, sealing and cooling time.
• Liquids and powders. The vacuum is drawn in the whole chamber, so sauces, marinades and powders stay in the bag.
• Stainless steel and a clear lid. The chamber is stainless steel and the lid is transparent, so the operator sees the bag through the whole cycle.

Operation and operator tasks with DOZE400TB

During operation, the operator should check that the bag mouths are clean and flat on the bars, as folds or contamination can cause weak seals. For liquids or powders, care must be taken to avoid overfilling bags or running the vacuum too long, which can cause product to boil or spill.

How a cycle runs

1. Switch the machine on and choose a program (P0–P9) for the product you are packing.
2. Lay the filled bags in the chamber, each with its open end flat over one of the two bars.
3. Press the lid down, the cycle starts by itself and the panel shows which step is running.
4. The pump evacuates the chamber, then both bars seal and the seals cool.
5. Air returns, the lid opens and both bags come out at once.

Settings and consumables

• Vacuum time. 0 to 99 s. A deeper vacuum needs longer; with liquids stop before the product starts to boil in the chamber.
• Sealing and cooling time. 0 to 9.9 s each. Thicker and aluminium-laminated bags need a longer seal, and the cooling time is what sets it.
• Programs. Ten settings, P0 to P9, one per product or bag.
• Bags. Smooth chamber vacuum bags, barrier films and aluminium-laminated bags.
• Filler blocks. A small product in a 440 × 420 chamber wastes vacuum time, a PP or nylon block beside it fills the space and shortens the cycle.
• Pump oil. No.68 or No.100 vacuum oil, between 1/3 and 1/2 of the oil window; do not run the machine without a bag inside.

Before you order

The price is on this page. A chamber machine is bought for the product that has to fit inside it, so check these before you order:

• Product size. The chamber is 440 × 420 × 75 mm and the filled bag has to lie flat in it.
• Bag mouth. Up to 400 mm per bar, two bags per cycle.
• Output. Two bags per cycle at 20 m³/h. If that is not enough, the double-chamber DOZE600 works with one chamber while the other is being loaded.
• Bench or floor. This is the bench model. DOZE400B has the same chamber and the same bars on a cabinet, at working height.
• Gas flush. This model packs under vacuum only. Tell us before you order if the product needs a protective atmosphere (MAP).
• Supply. 220 V / 50 Hz single phase, about 0.9 kW.
• Delivery. The machine travels in a crate of 620 × 570 × 565 mm, about 80 kg.

Choosing and using the DOZE400TB chamber vacuum sealer

Common mistakes include overfilling bags, trapping product in the seal area, or setting sealing times too short for thick or laminated bags, which can cause leaks. Always test new bag types or products with a few cycles to confirm settings. For perishable foods, vacuum packaging extends shelf life but does not replace refrigeration; keep vacuum-packed items chilled as required for safety and quality.
