VACUUM MACHINE DEFINITIONS & OPTIONS

Back to Vacuum Machines Definitions Vacuum Pack Options

DEFINITIONS
Chamber Vacuum Machine	A vacuum machine with a stainless steel box (chamber) that has a seal bar or bars to seal the pouch. The air is pulled from the entire chamber during the vacuum process, the bag is sealed and then the air is let back in the chamber. Uses the flat, commercial vacuum pouches.
Clamp-Style Vacuum Machine	A Home Type Vacuum Machine that must use a channel vacuum pouch.
Clean Room Compatible Vacuum Machines	Vacuum machines that use a compressed air venturi vacuum pump. Most are Retractable Nozzle Machines
Double Chamber Vacuum Machine	A chamber vacuum machine that has two vacuum chambers speeding up production by 30 to 40%. May have two separate chambers or a swing lid where the two chambers share a lid that swings from one side to the other to effect the vacuum and seal.
Gas Flush	A system on a vacuum machine that injects an inert gas such as nitrogen or carbon dioxide into the pouch creating a pillow pack. More info can be found here.
Home Type Vacuum Machine	A smaller, clamp-style vacuum machine that must use a channel vacuum pouch to remove the air.
Inert Gas Kit	Same as Gas Flush.
Pillow Pack	A loose vacuum package created with Gas Flush.
Retractable Nozzle Vacuum Machine	A table-top vacuum machine that clamps the open end of the pouch shut while the air is being evacuated through a retractable snorkel or tube that pulls the air out of the pouch. These machines are normally clean room compatible since they have a compressed air venturi vacuum pump. Uses the flat, commercial vacuum pouches.
Seal Bars	Seal bars are found on all vacuum machines. They are the part that actually seals the bag via impulse seal (time) or validatable seal (temperature) control. The length of the seal bar is the length down the bar (or the biggest pouch opening you can place on the bar); the seal width is the actual width of the seal element (1/8", 4mm, 1/4", etc.) There can also be on some seal bars a cut-off element which is a round wire that runs parallel to the main seal element. This allows the excess end length of a pouch to be removed after sealing.
Table Top Chamber Vacuum Machine	A smaller chamber machine that is short enough to sit on a table.
Validatable Vacuum Machines	Used in critical sealing applications (medical, pharmaceutical, labs, etc.) where the pouch seals MUST meet rigid quality control standards. Validatable machines generally seal by temperature, not by time.
Vacuum Pouch	Vacuum pouches are the bags used for vacuum packing and are usually made of multi-layered nylon and polyethylene. Other materials are added to some pouches for specific purposes such as higher oxygen barrier for products that must be kept away from oxygen. Pouches are available in two different types: flat, commercial pouches and channel pouches for the home style machines. More on pouches here.

VACUUM MACHINE OPTIONS
Not all options available on all machines!

Gas Flush A system on a vacuum machine that injects an inert gas such as nitrogen or carbon dioxide into the pouch creating a pillow pack. More info can be found here.

Slant Tray A stainless steel fixture that fits inside the chamber to allow packaging of liquids and/or loose items (beads). The slant tray angles down from the top of the seal bar to the opposite side of the chamber so gravity can keep the liquids in the pouch.

Seal Bar Options Lets you improve the quality of the seal by either increasing the seal element width or by replacing a cut-off wire with another seal element. The two 4mm seal option is definitely a better seal IF you don't need to tear-off any excess bag length.

Forming Box Larger Picture
The forming box is a mold used for forming “coffee” or whatever type of product into the shape of a square or “brick”. Only available with the MVS-38.

Increased Chamber Height A taller lid available on some chamber machines to allow packing higher product than normal.

Bi-Active Sealing A sealing system that has elements on BOTH sides of the seal bar (top and bottom). This is required when sealing folded (gusseted) or very thick vacuum pouches.

Voltage Options An electrical option that lets you change the standard voltage and/or phase of the machine. Most larger chamber machines come standard as 208 volt/60/3 phase. The option on them is to go to 220 volt/60/1 phase for facilities that do not have three phase power. The horsepower (power) of the pump usually lower, too.

Stainless Construction Machines that have this option available are made of easy-to-clean stainless steel. This is an important option for medical and pharmaceutical plants where cleaning is an important step. Our chamber machines come standard in stainless steel.
