Two families of vacuum machines, two different economies<\/h2>\n

\u201cVacuum machine\u201d on the RFQ form covers two different technologies. The chamber machine places the entire bag inside a vacuum chamber\u2014air is drawn out of the chamber and the bag simultaneously. The nozzle machine inserts a suction nozzle into the open neck of the bag\u2014the bag is moved, not the chamber. This one-sentence difference determines the machine's cost, speed, and the bag sizes it can handle.<\/p>\n

A strategic comparison of vacuum versus vertical form-fill-seal (VFFS) machine lines is already available. Vacuum packaging vs VFFS<\/a> \u2014 the article answers \u201cdo we need a vacuum at all.\u201d This one answers the second question: \u201cwhich vacuum cleaner.\u201d A depiction of the automatic vacuum lineup in Automatic vacuum packaging machine<\/a>.<\/p>\n

Chamber: bag goes into the box<\/h2>\n

The bag is placed in a sealed chamber; the pump draws air from the entire chamber until the pressure drops; the internal and external pressures of the bag equalize, then the sealing jaws close the bag before air is allowed back in. Results: the deepest vacuum (residual oxygen below 11 ppm), uniform compression, and the option of gas flushing (nitrogen for cheese and soft products \u2014 the bag does not fully adhere to the product).<\/p>\n

Speed: 20\u201340 second cycles \u2014 single table 1\u20132 bags per minute, alternating dual-chamber 3\u20134 bags\/min (operator loads one chamber while the second chamber is running). Bag size is limited by chamber size: the tabletop model accepts A4 bags, the floor model up to 50 \u00d7 40 cm. For meat, cheese, fish, and retail cuts \u2014 this is the standard machine.<\/p>\n

Nozzle: suck the bag necks one by one<\/h2>\n

The suction nozzle is inserted into the neck of the open bag (pre-made 5\u201325 kg bags), the pump draws out the air, and the nozzle is withdrawn as the jaws or clips seal the bag. No chamber means no bag size limit \u2014 this is the only technology for 25 kg rice sacks, 10 kg factory beans, and bulk frozen foods.<\/p>\n

Speed: 20\u201360 seconds per bag depending on size; a conveyor line with 2\u20134 nozzles reaches 4\u20138 bags per minute with two operators. The vacuum is shallower than in a chamber (residual oxygen 1\u201331 ppm) because the bag neck remains open during evacuation\u2014enough for beans and grains, not for fresh meat for weeks.<\/p>\n

Six questions that determine the model<\/h2>\n
    \n
  1. Largest bag size<\/strong> \u2014 immediately closes the chamber\/nozzle debate.<\/li>\n
  2. Targeted residual oxygen<\/strong> \u2014 below 1% (oxide-sensitive fat, meat) = chamber; 1\u20133% sufficient (roasted beans) = both.<\/li>\n
  3. Day bag<\/strong> \u2014 under 200 tables; 200\u20132,000 dual-chamber; large bags 300+ conveyor nozzles.<\/li>\n
  4. Wet or dry product<\/strong> \u2014 liquids boiled at low vacuum (coconut milk, marinades require a chamber with a liquid-stop function or a controlled suction level).<\/li>\n
  5. Gas flush needed?<\/strong> \u2014 cheese, soft products, long-distance export: yes. Standard chamber supported; nozzle limited.<\/li>\n
  6. Pump \u2014 capacity and oil<\/strong> \u2014 dry vs. wet pumps, service reach and maintenance kit prices. The pump is the heart of the machine; the jaw gasket wears out every 6\u201312 months with daily use.<\/li>\n<\/ol>\n
