AS-4 Tray Vacuum Gas Flushing Sealing MAP Packing Machine is

vertical type vacuum and gas-flush pneumatic tray sealing system,

vacuums the tray completely before it inserts gas.The machine is

built in stainless steel for use in hygienicenvironments.The system

is tooled up to your specific tray size and neatly trims the film

around the perimeter of the tray, the wasted film is then taken up

onto the motorized film feeding system.This machine requires a

compressed air connection.

Main Function:

The food trays are manually placed in the tray carrier drawer.As a

safety precaution, the operation is initiated by the two handed

release system.

The tray carrier moves automatically into the machine and the

machine head comes down and seals around the tray carrier.

The large capacity vacuum pump efficiently evacuates the chamber

and the gas-flush is carried out.

The sealing head then moves downcompleting the perimeter sea

around the tray as wellas a neat perimeter cut.

The tray carrier drawer then automatically moves back out to the

operator and the trays may be removed.

While removal and reloading of the trays takes place,the film is

automatically fed to the new position.The new position is

determined by either time,blank film counting

(to calculate the film length of tray for saving the film cost) or by

photocell sensor mark(for printed film).
