DOZE300T chamber vacuum sealer, 260 mm seal bar, 10 m³/h

DOZE300T tabletop chamber vacuum sealer

DOZE300T is a tabletop chamber vacuum sealer. The bag is laid inside the chamber, the lid is pressed down and the machine evacuates the whole chamber, seals the bag and lets the air back in, so the vacuum is drawn around the product, not only out of the bag. That is why a chamber machine packs liquids, sauces, powders and marinades that an external sealer cannot hold.

The chamber measures 385 × 280 × 50 mm and the single sealing bar is 260 × 8 mm, which is the widest bag mouth the machine seals. The 10 m³/h pump gives a typical cycle of 10 to 20 seconds, depending on the product and the bag.

Times are set on the panel and kept: vacuum time from 0 to 99 s, sealing and cooling from 0 to 9.9 s, and ten programs P0–P9 hold a setting each, so a different product does not have to be set up again.

The machine is a benchtop unit of about 490 × 450 × 320 mm on 220 V / 50 Hz, so it stands on a normal worktable, and the transparent lid keeps the whole cycle in sight.

DOZE300T in packaging operations

DOZE300T is used in small to medium food processing, catering, and central kitchens for portioning and shelf-life extension of meats, cheeses, sauces, and prepared foods. It is also applied in laboratories for moisture-sensitive samples, and in light manufacturing for packaging kits, fasteners, and consumables. The compact footprint and single-phase power allow installation in offices, technical departments, and auxiliary workspaces where bench space is limited.

What a chamber machine does better

• Liquids and pastes as well. The vacuum is drawn in the whole chamber, so sauces, soups, marinades and pastes do not get sucked into the pump the way they do on an external sealer.
• A repeatable seal. Vacuum, sealing and cooling time are set in seconds and stored in a program, so the tenth bag is sealed exactly like the first.
• Ten programs. P0 to P9, one for every product or bag you pack regularly.
• A seal that holds. A single bar 260 × 8 mm with a silicone counter strip; the strip can take letters and numbers, which emboss a mark into the seal.
• It stays on the table. About 490 × 450 × 320 mm, 220 V, a normal socket, no compressed air and no three-phase supply.
• Longer shelf life. Air out means less oxidation and no mould growth, and soft goods take up less room once the air is out of them.

How a cycle runs

Operators should ensure the bag mouth is flat across the sealing bar and that the product height does not exceed the 50 mm chamber limit. Before each cycle, the sealing area should be free of product residue to maintain seal integrity. For liquids, avoid overfilling and watch for signs of boiling during vacuuming, adjusting the vacuum time as needed.

1. Switch the machine on and choose a program (P0–P9) for the product you are packing.
2. Put the filled bag into the chamber with its open end lying flat over the sealing bar.
3. Press the lid down, the cycle starts by itself and the panel shows which step is running.
4. The pump evacuates the chamber for the set time, then the bar seals the bag and the seal cools.
5. Air returns to the chamber, the lid opens and the bag is taken out; the next bag can go in.

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. A thicker bag needs longer sealing, and the cooling time is what makes the seal firm.
• Programs. Ten settings, P0 to P9, one per product or bag.
• Bags. Smooth chamber vacuum bags, typically 70–100 μm; embossed bags for external sealers are not needed here.
• Filler blocks. A small product in a large chamber wastes time, a PP or nylon block put in 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. Never run the machine without a bag inside, as the heating element wears faster.

DOZE300T: selection and integration

The benchtop design requires a rigid worktable with enough vertical clearance for the lid to open fully. The single-phase 220 V / 50 Hz supply avoids the need for special wiring or compressed air, making the unit easy to relocate as workflows change. When integrating into a packing line, consider the cycle time and plan for staging of filled bags and removal of sealed pouches to match the desired output rate.

Operation and maintenance of DOZE300T

Routine checks include inspecting the sealing bar and the silicone counter strip for wear, and keeping the chamber and sealing area clean. The lid gasket and hinge should be checked periodically to maintain alignment and sealing performance. For each product or bag changeover, verify and log the correct program settings to minimize reject rates and ensure repeatable results. Consumables such as heating elements should be kept in stock for timely replacement.

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 385 × 280 × 50 mm, the filled bag has to lie flat in it. For taller products choose DOZE400TB or DOZE400B with a 75 mm chamber.
• Bag mouth. Up to 260 mm, the length of the sealing bar.
• Output. A cycle of 10–20 s means roughly 3 to 6 bags a minute. Above that the double-bar DOZE400TB or the double-chamber DOZE600 is the machine to look at.
• Gas flush. This model packs under vacuum only. If the product needs a protective atmosphere (MAP), tell us before you order.
• Supply. 220 V / 50 Hz single phase, about 0.4 kW.
• Delivery. The machine travels in a crate of 590 × 430 × 400 mm, about 40 kg.
