DOZE300T Chamber Vacuum Sealer, 260 mm Seal Bar, 10 m³/h

DOZE300T Tabletop Chamber Vacuum Sealer

The DOZE300T is a tabletop chamber vacuum sealer. Place the bag inside the chamber, close the lid, and the machine removes air from the entire chamber, seals the bag, and then releases the vacuum, so the vacuum forms around your product, not just inside the bag. This lets a chamber sealer package liquids, sauces, powders, and marinades that an external vacuum sealer cannot handle.

The chamber measures 385 × 280 × 50 mm, and the single sealing bar is 260 × 8 mm, which is the maximum bag opening the machine can seal. The 10 m³/h vacuum pump delivers a typical cycle time of 10 to 20 seconds, depending on your product and bag size.

You set the times on the control panel and they are saved: vacuum time from 0 to 99 s, sealing and cooling from 0 to 9.9 s each, and ten programs P0–P9 store individual settings, so you don’t have to reprogram for different products.

This is a benchtop model measuring about 490 × 450 × 320 mm and runs on 220 V / 50 Hz, so it fits on a standard worktable. The clear lid lets you watch the entire process.

DOZE300T in Packaging Applications

The DOZE300T is used in small and medium food processing, catering, and commissary kitchens for portioning and extending shelf life of meats, cheese, sauces, and prepared foods. It’s also used in labs for packaging moisture-sensitive samples, and in light manufacturing for packing kits, fasteners, and consumables. Its compact size and single-phase power make it easy to use in offices, technical rooms, and other workspaces with limited bench space.

Advantages of a chamber vacuum sealer

• Handles liquids and pastes. The vacuum is created inside the chamber, so items like sauces, soups, marinades, and pastes stay in the bag and don’t get pulled into the pump as they might with an external vacuum sealer.
• Consistent sealing results. Vacuum, seal, and cooling times are programmed in seconds and saved, so every bag is sealed identically, from the first to the last.
• Ten programmable settings. P0 through P9, so you can store a setting for each product or bag you seal often.
• Reliable seal quality. One sealing bar, 260 × 8 mm, with a silicone backing strip; the strip can hold letters and numbers to emboss a code into the seal.
• Compact for countertop use. Measures about 490 × 450 × 320 mm, runs on 220 V from a standard outlet, and does not require compressed air or three-phase power.
• Extends product shelf life. Removing air reduces oxidation and prevents mold, and soft items take up less space after vacuum sealing.

Cycle Operation

Make sure the bag opening is laid flat on the sealing bar and that your product does not exceed the 50 mm chamber height. Before each run, check that the sealing area is clean and free of product to ensure a proper seal. For liquid products, do not overfill and monitor for boiling during vacuuming, adjusting the vacuum time as needed.

1. Turn on the chamber vacuum sealer and select the appropriate program (P0–P9) for your product.
2. Place the filled bag inside the chamber, making sure the open end is flat on the sealing bar.
3. Push the lid down to start the cycle automatically; the control panel will display the current step.
4. The pump draws air from the chamber for the programmed time, then the sealing bar closes the bag and the seal cools.
5. Air is let back into the chamber, the lid opens, and you can remove the sealed bag and load the next one.

Settings and Supplies

• Vacuum time. Adjustable from 0 to 99 seconds. A longer setting creates a stronger vacuum; for liquids, stop before the product boils in the chamber.
• Sealing and cooling time. Each can be set from 0 to 9.9 seconds. Thicker bags require more sealing time, and cooling ensures the seal is strong.
• Programs. Ten programmable options, P0 through P9, to match different products or bag types.
• Bags. Use smooth chamber vacuum bags, usually 70–100 μm thick; you do not need textured bags for this sealer.
• Filler blocks. If your product is small for the chamber, add a PP or nylon block to fill space and reduce cycle time.
• Pump oil. Use No.68 or No.100 vacuum oil, filling to between 1/3 and 1/2 of the oil sight glass. Always operate the chamber vacuum sealer with a bag inside to prevent premature wear of the heating element.

DOZE300T: Choosing and Integrating

This benchtop chamber vacuum sealer needs a sturdy table and enough height for the lid to open fully. It runs on single-phase 220 V, 50 Hz power, so no special wiring or compressed air is required, making it easy to move as your workflow changes. When adding it to a packing line, consider the cycle time and plan for staging filled bags and removing sealed pouches to keep up with your production rate.

How to operate and maintain the DOZE300T

Regular maintenance includes checking the seal bar and silicone counter strip for any signs of wear, and making sure the chamber and sealing area are always clean. Inspect the lid gasket and hinges from time to time to keep the lid aligned and ensure a proper seal. When switching to a different product or bag, confirm and record the correct program settings to reduce rejects and achieve consistent results. Keep spare heating elements and other consumables on hand for quick replacement when needed.

What to know before purchasing

You’ll find the price listed on this page. Chamber machines are selected based on the size of the items you need to package, so please review the following points before placing your order:

• Product size. The chamber measures 385 × 280 × 50 mm, and the filled bag must fit flat inside. For taller items, consider the DOZE400TB or DOZE400B, which have a 75 mm chamber height.
• Bag opening. Maximum width is 260 mm, matching the length of the seal bar.
• Output. Each cycle takes 10–20 seconds, so you can seal about 3 to 6 bags per minute. For higher throughput, look at the double-bar DOZE400TB or the double-chamber DOZE600.
• Gas flush. This model is designed for vacuum sealing only. If you require modified atmosphere packaging (MAP), please let us know before ordering.
• Power supply. 220 V / 50 Hz, single phase, approximately 0.4 kW.
• Collection. The machine is packed in a crate measuring 590 × 430 × 400 mm and weighs about 40 kg. Goods are collected EXW and prices do not include VAT.
