Applications of DZ400 Vacuum Packaging Machine

• Food Processing: Vacuum packaging for meat, fish, cheese, and prepared foods. The 304 stainless steel chamber is ideal for food contact applications and easy sanitization.
• Small Food Businesses: Packaging for delis, butcher shops, and small food producers. The economical single chamber design is cost-effective for lower volume operations.
• Medical and Healthcare: Vacuum sealing for medical instruments, sterile supplies, and healthcare products requiring airtight, contamination-free packaging.
• Electronics: Packaging electronic components, circuit boards, and sensitive devices to prevent moisture, oxidation, and static damage during storage and shipping.
• Hardware and Industrial: Vacuum packaging for metal parts, tools, and industrial components to prevent corrosion and oxidation during long-term storage.
• Agricultural Products: Vacuum sealing for seeds, nuts, dried fruits, and agricultural products to extend shelf life and maintain quality.

304 Stainless Steel: Why It Matters for Food Packaging

The DZ400 uses 304 stainless steel for its vacuum chamber, which is the industry standard for food-grade equipment. 304 stainless steel contains 18% chromium and 8% nickel, providing excellent corrosion resistance, acid resistance, and heat resistance. This material is non-reactive with food products, does not leach chemicals, and can withstand repeated cleaning with sanitizing chemicals.

Compared to painted carbon steel or lower-grade stainless steel, 304 stainless steel provides superior hygiene, easier cleaning, and longer service life. It is resistant to food acids, salt, and common cleaning chemicals. For food processing applications, 304 stainless steel is essential for compliance with FDA, CE, and international food safety standards. The material also maintains its appearance over time, without rusting or deteriorating in humid food processing environments.

Frequently Asked Questions

What sealing length options are available for the DZ400?

The DZ400 is available with sealing lengths of 400mm, 500mm, 600mm, or 800mm. The sealing length determines the maximum bag width the machine can accommodate. The 400mm model is the standard configuration, suitable for most food packaging applications. The 500mm and 600mm options are recommended for larger products or multi-item packaging. The 800mm option is for industrial applications requiring very large bags. The sealing length is fixed at the time of manufacture and cannot be changed after purchase.

Can the vacuum chamber depth be customized?

Yes, the vacuum chamber depth can be customized according to your product size requirements. The standard chamber depth is 100mm, but we can manufacture chambers with depths of 150mm, 200mm, or custom depths up to 300mm. Deeper chambers accommodate taller products such as bottles, jars, or tall food containers. When ordering, please specify your required chamber depth or send us your product dimensions for a recommendation.

How does the DZ400 compare to the VM series?

The DZ400 is a single chamber machine, while the VM series includes both single and double chamber models. The DZ400 is more economical and simpler in design, making it ideal for small operations with lower packaging volumes (50-150 packages per hour). The VM series offers higher throughput with double chamber designs, more powerful vacuum pumps, and more advanced control systems. Choose the DZ400 for cost-effective small-scale packaging, or the VM series for higher volume operations.

What type of vacuum bags should I use?

The DZ400 uses standard flat vacuum bags (not embossed/channel bags) since the entire bag is placed inside the vacuum chamber. We recommend bags made from PA/PE (nylon/polyethylene) or PET/PE composite materials with a thickness of 0.08-0.15mm. The bag width should not exceed the sealing length of your machine. For products with sharp edges, use thicker bags (0.15-0.20mm) or add bone guard strips. We can supply compatible vacuum bags in various sizes.

How do I clean and maintain the machine?

Daily cleaning involves wiping the chamber interior with a food-safe sanitizer and drying with a clean cloth. The sealing bar should be cleaned of any adhesive residue after each use. Weekly maintenance includes checking the lid gasket for wear, cleaning the vacuum pump exhaust filter, and inspecting the heating element. Monthly maintenance includes checking and changing the vacuum pump oil, inspecting electrical connections, and verifying the accuracy of the vacuum gauge. The 304 stainless steel chamber is easy to clean and does not require special cleaning agents.

Is the machine suitable for commercial food production?

Yes, the DZ400 is suitable for commercial food production with its 304 stainless steel construction, CE certification, and food-grade design. It is commonly used in butcher shops, delis, small food processing facilities, and restaurants. For larger commercial operations processing more than 150 packages per hour, we recommend upgrading to a double chamber VM series machine for higher throughput.

What is the delivery time and shipping method?

Standard DZ400 models are typically in stock with 7-15 days delivery. Custom configurations with specific sealing lengths or chamber depths require 20-30 days production time. We ship worldwide via sea freight (economical for heavy machines) or air freight (faster but more expensive). The machine is packed in a wooden crate for secure transport.
