Commercial Single Chamber Vacuum Packing Machine (DZ-400S)

The CECLE Commercial Single Chamber Vacuum Packing Machine (Flagship Model DZ-400S) is an industrial-grade vacuum packaging equipment engineered specifically for food processing, culinary kitchens, pharmacies, medical herb dispensaries, and industrial parts packaging. It utilizes a deep enclosed vacuum chamber, thoroughly breaking the limitations of traditional external suction edge sealers. It can perfectly handle liquids, high-moisture foods, and fragile medical herbs without drawing liquids into the pump or crushing fragile items. Driven by a high-displacement industrial rotary vane vacuum pump (20m³/h) + microcomputer digital control system + robust 400mm double sealing bars, this equipment can extract up to 99.9% of the air/oxygen, significantly extending shelf life, preventing oxidation, and inhibiting the growth of aerobic bacteria. The equipment features a heavy-duty all-stainless steel floor-standing chassis design, with universal wheels at the base for easy mobility. It is the ultimate benchmark choice for commercial operations seeking reliable, high-speed, and high-airtightness packaging.

CECLE Commercial Single Chamber DZ-400 Medical Herbs & Food Vacuum Packing Machine

1. Product Overview

1. Basic Equipment Information

  • Product Name: Commercial Hot-Selling Medical Herbs, Food & Liquid Vacuum Packing Machine (Single Chamber DZ Series)
  • Core Model: DZ-400S (Supports upgrade to DZ-500S / DZ-600S within the same series)
  • Equipment Type: Floor-standing Single Chamber Vacuum Sealer
  • Market Positioning: Designed for restaurants, butcher shops, medical herb clinics, liquid/sauce production facilities, electronic component manufacturers, and high-capacity commercial prep kitchens.

Engineering & Manufacturing Highlights:

  • Industrial Rotary Vane Vacuum Pump: Equipped with a 0.9KW heavy-duty oil-lubricated vacuum pump with a pumping speed of up to 20m³/h, capable of rapidly reaching absolute vacuum levels. It can withstand continuous commercial workloads and ensures maximum air extraction.
  • Deepened Stainless Steel Vacuum Chamber: The vacuum chamber and outer casing are made of thick, food-grade 304 stainless steel. The base depth is 70mm and supports height customization (100mm/200mm/300mm), accommodating large cuts of meat, bulk medical herbs, or large-capacity liquid bags.
  • Microcomputer Digital Control Panel: Equipped with an intuitive, waterproof digital interface, allowing precise adjustment of "Vacuum Time", "Sealing Time", and "Cooling Time".
  • True Liquid Handling Capability: Because the pressure in the entire vacuum chamber (inside and outside the bag) drops proportionally at the same time, liquids (soups, marinades, herbal extracts) can be safely kept in the bag during the vacuum cycle, perfectly sealed without messy spills.

2. Core Functions & Working Principles

  • Atmospheric Evacuation: Close the lid to form an airtight seal. The vacuum pump starts, quickly pumping out the air in the entire vacuum chamber (including the inside of the unsealed bag containing the product).
  • Impulse Heat Sealing: After reaching the target vacuum degree, the pneumatic airbag pushes the heat-sealing bar tight against the packaging bag. An electrical impulse heats the Teflon-coated nichrome wire, fusing the bag layers together to form a permanent airtight seal.
  • Pressure Restoration & Cooling: Normal air pressure is instantly restored in the vacuum chamber. This pressure difference makes the bag shrink tightly around the product. The pneumatic hydraulic rod automatically releases and pops open the lid.

3. Core Value: Why Choose DZ Series Chamber Sealers?

  • Complete Oxygen Elimination (Shelf Life Extended 5x): Removes oxygen to prevent oxidation, discoloration, and mold. Medical herbs retain their essential oils and efficacy; meat avoids freezer burn; dry goods stay crisp for months or years.
  • Universal for All Mediums (Dry, Wet, Liquid, Powder): External suction sealers struggle to handle liquids and fine powders. The DZ series handles them effortlessly.
  • Massive Savings on Consumable Costs: Chamber sealers use standard smooth commercial vacuum bags (flat bags). These smooth bags are much cheaper than the textured bags that household machines must use, drastically reducing long-term operating costs.

2. Standard Operating Procedures (SOP) & Production Workflow

To ensure perfect sealing airtightness and prolong the service life of the vacuum pump and heating elements, please strictly adhere to the following protocols:

1. Bag Preparation & Product Loading

  • Select the Right Packaging Bag: Use standard smooth commercial vacuum bags. Ensure the bag is wide enough for the product but must be within the sealing bar length limit of the machine (e.g., 400mm for DZ-400S).
  • Leave Top Space: When packaging liquids, sauces, or large pieces of herbs, leave at least 2 to 3 inches (5-8 cm) of empty space at the top of the bag. This ensures the sealing area remains clean and flat.
  • Clean the Sealing Area: Wipe away any moisture, grease, or herbal dust from the inside top opening of the bag. Contaminants can cause weak or leaking seals.

2. Programming the Digital Control Panel

  1. Power On: Turn on the main power switch.
  2. Set Vacuum Time: Usually between 15 to 30 seconds, depending on the size of the product and packaging bag. (Note: For fragile herbs or soft bread, please reduce the time to avoid crushing).
  3. Set Sealing Time: Usually between 1.2 to 2.5 seconds, depending on the thickness of the vacuum bag.
  4. Set Cooling Time: Usually set to 2.0 to 3.0 seconds, allowing the heated and melted plastic to solidify under pressure before opening the vacuum chamber.

3. Preventative Maintenance & Vacuum Pump Care

  • Vacuum Pump Oil Change (Crucial):
  • First Oil Change: Must be performed after the first 100 hours of operation.
  • Routine Oil Change: Change the oil every 250 to 300 hours of operation, or whenever the oil in the sight glass appears cloudy, emulsified, or dark.
  • Sealing Bar Maintenance: If the high-temperature Teflon tape turns brown, tears, or sticks to the bags, please replace the Teflon tape and heating wire immediately to prevent short circuits.

4. Frequently Asked Questions (FAQ)

  • Q: Can this machine vacuum package liquids like soups or medical herbal extracts?
  • A: Absolutely. Chamber vacuum packaging machines are the only devices that can truly vacuum package liquids. Because the pressure drops uniformly across the entire vacuum chamber, liquids will not boil over or get sucked out of the bag during the vacuum stage.
  • Q: Why does this machine require pump oil? What kind of oil should I use?
  • A: The machine is equipped with a 0.9KW industrial-grade rotary vane vacuum pump (displacement 20m³/h) to achieve maximum air extraction and commercial longevity. Pump oil is used to lubricate the vanes and dissipate heat. You should use dedicated vacuum pump oil (usually ISO VG 32 or 68, subject to the manual).
  • Q: Will it crush my fragile medical herbs or soft foods?
  • A: If set to maximum vacuum, atmospheric pressure might crush fragile items. To prevent this, you simply need to reduce the "Vacuum Time" on the digital panel, thereby creating a "partial vacuum" that preserves the product without destroying its physical structure.
