I. Product description and usage
DZ series vacuum packing machine is used for removing air
from the package and sealing the mouth of bag. Vacuum packing
reduces atmospheric oxygen, limiting the growth of aerobic
bacteria or fungi, and preventing the evaporation of volatile
components.
The 2 chambers work in turn: when one chamber is pumping and
sealing , workers can place product to packing on the other chamber,
so that it is more efficient than single chamber.
DZ series double chamber vacuum packing machine combine a
sleekly built and functional design with optimal ease of use and a
long service life. The clever design ensures compliance with the
hygiene standards at all times.

Vacuum pump
Step 1 vacuum. There is an air bag between sealing bar and lid. When
the pump is working, the air in the air bags and vacuum chamber is
vacuumed simultaneously, so that the sealing bars and silicon bars not
close up.
Step 2 thermal seal. When the vacuuming finished, to inflate the air
bags the solenoid YV1 switches on , and the vacuum chamber keep
vacuum.
Step 3 devacuum. To let air enter the chamber, the solenoid YV2
switches on, the chamber open, the entire process is finished.

VII. Programming
1. Vacuum time range: 0 to 99 s.. (Normally 20 s., and for liquid, 25 s is
recommended.)
2. Sealing time range: 0 to 3.5 s.. (normally 1.5 s., and for thick film or
with aluminum layer, 3 s..)
3. Level of sealing temperature: low, medium, high.(for thick film or with
aluminum layer, select 'high')
4. Cooling time (holding time): 2 s. by default. To prevent aluminum from
wrinkle, 15 s. is recommended.
Instruction
