YAHE model MAP-YHH400 is a new generation M.A.P. sealing machine combined several national patents in, as following:
ZL201320184529.4  a gas proportioner;
ZL201320166045.7 a film tensioning device for modified atmosphere packaging machine;
ZL20132 0167388.5 a multifunctional modified atmosphere packaging machine;
ZL201220365757.7 a packaging machine;
ZL201220365750.5 a heat-seal device for tray MAP sealing machine;

This machine is featured as high air exchanging rate, less gas mixing accuracy error, high working speed; as added alarm system, error information and troubleshooting instruction, it has very friendly human-machine interface; very easy to perform operation and maintenance. Different programs are preset in the controller for packaging different food products (gas mixing proportion varies for different food products), which helps improve operation efficiency and convenience significantly.
