DOZE400B industrial vacuum sealer 400 mm – 20m³/h

DOZE400B floor-standing chamber vacuum sealer

DOZE400B is a chamber vacuum sealer on its own cabinet: the chamber stands at working height, so the operator loads it standing up and no table has to be given up to it. Inside it is the same machine as the tabletop DOZE400TB, a 440 × 420 × 75 mm chamber, two sealing bars of 400 mm and a 20 m³/h pump.

Two bags are sealed in one cycle. The vacuum is drawn in the whole chamber, so liquids, marinades, powders and pastes are packed as easily as dry goods, and the 75 mm depth takes products that will not lie flat in a shallower machine.

The DOZE400B is used in food processing, pharmaceuticals, electronics, and chemical manufacturing, where products require protection from air, moisture, and contamination. It is suitable for packaging meats, seafood, cheese, coffee, spices, powders, pastes, liquids, electronic components, and chemical samples. The machine is designed for medium and large-scale production environments, including packaging lines and packing rooms where shelf life and product integrity are important.

At the workstation, the operator selects a program for the specific product, loads the bags, and monitors the process through the transparent lid. The panel displays the current step, and indicator lights show the cycle status. The operator checks that bag mouths are flat and free of folds on the sealing bars, and ensures the chamber is not overloaded before starting the cycle. For liquids, the vacuum time is set to prevent boiling during the process.

Times are set on the panel: vacuum 0 to 99 s, sealing and cooling 0 to 9.9 s, with ten programs P0–P9, so a change of product is a change of program.

The body is stainless steel with a transparent lid, the machine weighs about 120 kg and runs on a 220 V socket at about 0.9 kW.

DOZE400B vacuum sealer in production and industry

The DOZE400B is used in food processing, pharmaceuticals, electronics and chemical manufacturing. It is chosen where products need protection from air, moisture and contamination. Typical goods include meats, seafood, cheese, coffee, spices, powders, pastes and liquids, as well as electronic components and chemical samples. The machine is suited to medium and large-scale production, packaging lines, and packing rooms where shelf life and product integrity are critical.

In a packing line, the DOZE400B is placed at a workstation where filled bags are loaded into the chamber, sealed, and then moved to boxing or storage. Its floor-standing design keeps worktables clear.

Technical specifications

Operator tasks and process control on the DOZE400B

The operator selects a program for the product, loads up to two bags per cycle, and monitors the process through the transparent lid. The panel shows the current step, and indicator lights signal cycle status. The operator should check that bag mouths are flat and free of folds on the sealing bars, and that the chamber is not overloaded. For liquids, the vacuum time must be set so the product does not boil. The operator removes finished packs and prepares the next cycle. Regular cleaning of the chamber and sealing bars is part of daily use.

Before starting production, check that the vacuum oil is at the correct level and that the sealing elements and seal strips are in good condition. Spare heating elements and sealing strips should be kept on hand for quick replacement.

What the machine gives a packing room

• Working height. The chamber sits on its own cabinet, so it is loaded standing up and the worktables stay free.
• Two bags per cycle. Two sealing bars of 400 mm seal at the same time.
• A 75 mm chamber. Takes trays, blocks and filled bags that a 50 mm chamber will not.
• Liquids and powders. The vacuum is drawn around the product, so sauces and powders stay in the bag instead of being pulled into the machine.
• Ten programs. P0 to P9, each with its own vacuum, sealing and cooling time.
• Built for a packing room. A stainless steel body, an emergency stop and grounding protection, about 120 kg standing firmly on the floor.

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. Longer means a deeper vacuum; 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.
• 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.
• Floor or bench. DOZE400B stands on its own cabinet. If the machine has to go on a table, DOZE400TB is the same machine as a bench model.
• Output. Two bags per cycle. For more, the double-chamber DOZE600 keeps one chamber working while the other is being loaded.
• 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 570 × 630 × 1050 mm, about 130 kg.

Choosing and maintaining the DOZE400B vacuum sealer

Routine maintenance includes checking and changing vacuum pump oil, cleaning sealing bars and the chamber, and inspecting the silicone sealing strips. The stainless steel body and acrylic lid are easy to wipe down and keep hygienic.
