DZ-400/2S Automatic Filling and Sealing Machine

The DZ-400/2S is an electric-driven machine that automatically fills and vacuum-seals product packages. It is built for efficient, continuous small- to medium-scale packaging with a focus on durability, energy efficiency and ease of operation.

It is suitable for liquids, powders, granules and other commodity products used in food & beverage, chemical and general commodity packaging. Packaging material must be compatible with vacuum sealing and the product’s physical properties.

Sealing lengths are available in 400 mm, 500 mm and 600 mm with a standard sealing width of 10 mm. Typical chamber sizes (L×W×H) are approximately 435×420×40 mm (400 model), 525×420×40 mm (500 model) and 625×420×40 mm (600 model).

The machine uses an electric drive and can be configured for different regional power supplies. Common options include 110 V and 220 V; other configurations (such as 220/380 V) may be available—confirm exact voltage and Hz requirements with your supplier before ordering.

The DZ-400/2S uses a dual vacuum pump arrangement for faster evacuation. Typical rated capacity is around 20 m³/h per pump (dual-pump configuration). For motor power, exact values depend on model and region—refer to the detailed spec sheet from the manufacturer.

The machine has two vacuum chambers that operate alternately. While one chamber is being vacuumed and sealed, the other can be loaded/unloaded—this increases effective throughput and supports continuous small-scale operation.

The unit is compact and weighs approximately 80 kg. It should be placed on a stable, level bench or worktable with adequate ventilation and a properly grounded power outlet sized to the machine’s configured voltage.

The control panel includes a vacuum gauge and controls to set vacuum time, deflation time, sealing time and sealing temperature. Operation is user-friendly—close the vacuum chamber cover, set parameters, and start the cycle. Consult the user manual for recommended settings by product type.

Regular maintenance includes cleaning the stainless-steel chamber, inspecting and replacing worn sealing strips, checking chamber gaskets for leaks, monitoring vacuum pump oil (if oil-lubricated) and keeping heating elements free of residue. Follow the manufacturer’s maintenance schedule for pump servicing.

Common consumables include heat-resistant rubber sealing strips, sealing tape, chamber gaskets and vacuum pump consumables (oil, filters). The manufacturer or distributor typically supplies replacement parts.

Ensure the chamber cover is closed before starting a cycle, use the correct configured voltage and grounding, avoid sealing flammable or highly reactive materials without proper precautions, keep hands clear of sealing bars when active, and train operators in emergency stop procedures.

It can package liquids, but handling high-liquid or free-flowing liquids may require proper dosing/filling equipment and correct bag selection to prevent overflow during vacuuming. For heavy-liquid applications the supplier can advise on compatible fillers or process adjustments.

The product comes with online and video technical support for setup, troubleshooting and maintenance. Warranty terms and on-site support options vary—check with your supplier for warranty length, coverage and spare-parts availability.

Yes. Options commonly include different sealing lengths, chamber sizes, voltage configurations and accessory add-ons. Discuss specific customization or automation integrations with your supplier to match your production needs.

For poor seals: check sealing temperature/time, clean or replace worn sealing strips, verify proper bag placement and absence of debris on sealing surfaces. For weak vacuum: inspect chamber gasket for leaks, ensure vacuum pump is functioning and oil level/filters are correct. If the machine fails to start, verify power, emergency stop status and fuse/circuit protection.
