DOZE400TB Commercial Vacuum Sealer 400 mm – 20m³/h

DOZE400TB Tabletop Chamber Vacuum Sealer

The DOZE400TB is a tabletop chamber vacuum sealer equipped with two sealing bars. You can place two bags side by side in the chamber and seal both at once, so this model doubles your output per cycle compared to a single-bar machine of the same size.

The chamber is 440 × 420 × 75 mm, offering more depth than a 50 mm chamber, and each sealing bar handles bag openings up to 400 mm wide. The 20 m³/h vacuum pump quickly evacuates the chamber, keeping cycle times short even at full capacity.

You set vacuum, sealing, and cooling times on the control panel, with ten programmable settings P0–P9. Vacuum time is adjustable from 0 to 99 seconds, and sealing and cooling times from 0 to 9.9 seconds, ensuring consistent results for every bag.

This is still a benchtop unit: about 560 × 500 × 460 mm and 70 kg, runs on a 220 V outlet, and features a stainless steel chamber with a clear lid.

DOZE400TB for Production and Packaging Lines

The DOZE400TB tabletop chamber vacuum sealer is used in food processing, pharmaceuticals, electronics, and chemical industries where airtight packaging is essential to maintain product quality. It fits on a workbench or table and can be part of a small production line or used alone for batch packaging.

Common uses include vacuum sealing meat, cheese, ready-to-eat meals, sauces, powders, seeds, and electronic parts. The double bar setup is ideal for businesses needing to seal two bags per cycle, such as portioning food or assembling kits of small components.

Technical Data

Benefits of the double sealing bars and 20 m³/h pump

• Seal two bags at once. Both 400 mm sealing bars operate simultaneously, doubling your output with just one vacuum sealer.
• 75 mm deep chamber. This is deeper than the 50 mm found in smaller models, so you can seal blocks, trays, or filled bags that need extra space.
• 20 m³/h vacuum pump. Delivers twice the capacity of the 300 model, so the larger chamber does not increase cycle time.
• Ten programmable settings. P0 through P9, each with adjustable vacuum, sealing, and cooling times.
• Handles liquids and powders. The entire chamber is evacuated, so sauces, marinades, and powders stay inside the bag.
• Stainless steel body and see-through lid. The chamber is stainless steel and the lid is transparent, letting the operator monitor the bag throughout the process.

How to use the DOZE400TB and operator guidelines

When using the vacuum sealer, the operator should make sure the bag openings are clean and flat on the sealing bars, since folds or debris can weaken the seal. For bags with liquids or powders, avoid overfilling and do not run the vacuum too long, as this can cause the contents to boil or spill.

How a cycle works

1. Turn on the vacuum sealer and select the program (P0–P9) that matches your product.
2. Place the filled bags in the chamber, making sure the open ends are flat on the sealing bars.
3. Push the lid down, the cycle starts automatically, and the control panel displays the current step.
4. The pump removes air from the chamber, both bars seal the bags, and the seals are cooled.
5. Air flows back in, the lid opens, and both bags are ready at once.

Settings and supplies

• Vacuum time. Adjustable from 0 to 99 seconds. For a stronger vacuum, use a longer time. For liquids, stop before boiling starts in the chamber.
• Sealing and cooling time. Each can be set from 0 to 9.9 seconds. Thicker or aluminum-laminated bags need a longer seal, and the cooling time determines the seal strength.
• Programs. Ten options, P0 to P9, one for each product or bag type.
• Bags. Use smooth chamber vacuum bags, barrier films, or aluminum-laminated bags.
• Filler blocks. If your item is small for the 440 × 420 mm chamber, use a PP or nylon block to fill space and reduce vacuum time.
• Pump oil. Use No.68 or No.100 vacuum oil, fill to between 1/3 and 1/2 of the oil sight glass. Always operate the vacuum sealer with a bag inside.

Before you buy

You’ll find the price listed on this page. Since a chamber vacuum sealer must fit the item you’re packaging, please review these points before placing your order:

• Product size. The chamber measures 440 × 420 × 75 mm, and your filled bag must lay flat inside.
• Bag opening. Each sealing bar handles up to 400 mm, allowing you to seal two bags per cycle.
• Capacity. Processes two bags per cycle at a rate of 20 m³/h. If you need higher output, the DOZE600 double-chamber model lets you load one chamber while the other is running.
• Bench or floor model. This version is designed for use on a workbench. The DOZE400B offers the same chamber and sealing bars, but is built into a cabinet at standing height.
• Gas flush option. This model is for vacuum sealing only. If you require modified atmosphere packaging (MAP), please let us know before ordering.
• Power requirements. Runs on 220 V / 50 Hz single phase, approximately 0.9 kW.
• Collection. The machine is packed in a crate measuring 620 × 570 × 565 mm, with a total weight of about 80 kg. Goods are collected EXW and prices do not include VAT.

Selecting and operating the DOZE400TB vacuum sealer

Frequent issues include overfilling bags, getting product in the sealing area, or setting the seal time too short for thicker or laminated bags, which can result in leaks. Always test new bag types or products with several cycles to confirm your settings. For perishable foods, vacuum packaging helps extend shelf life but does not replace refrigeration; always keep vacuum-sealed products cold as needed for safety and quality.
