SIPROMAC INC.
VACUUM PACKAGING MACHINES
1. SETTING UP THE MACHINE:
Before choosing the site for the machine, please consider that you will also need room
for packaged and non-packaged products apart from the space needed for the machine
itself.
Keep in mind that the machine must not be set up upon uneven ground. Especially with
mobile models, the weight of the pump might then cause warping of the machine. Then
the lid will not fit correctly.
Before starting to work, check the oil view glass on the pump, if there is a sufficient
quantity of oil in the pump. Never use oil other than recommanded by the producer.
Never exceed maximum quantity of oil indicated, when adding or changing oil. Verify
weekly.
Normal ambient temperature for the vacuum pump is between 10 to 70
o
C.For
temperature below 10
o
C; it is recommended to use synthetic oil. Please consult
factory and pump manufacturer manual for more information or when ambient
temperature are outside normal limits
2. ELECTRICAL CONNECTION:
Electrical connections must be made by qualified personnel. This person must make
sure that the electrical entries corresponds to the proper voltage and amperage of the
machine. GROUNDING INSTRUCTIONS: This appliance must be connected to a
grounded, metal, permanent wiring system; or an equipment-grounding conductor must
be run with the circuit conductors and connected to the equipment-grounding terminal or
lead on the appliance. A qualified electrician should be consulted if there is any doubt
as to whether an outlet box is properly grounded.
All vacuum machines are supplied with an electrical schematic drawing.
An important step in connecting the machine is to make sure that the pump turns in
its correct rotation.
The pump should not rotate more than 3 to 4 seconds in the wrong rotation or it
may cause serious damage. The proper rotation is indicated by an arrow on the
pump motor.
3. OPERATION:
3.1 Working principles:
A vacuum packaging cycle is made of 3 stages. First the vacuum is made, the air is
completly taken out of the chamber and from bag containing the product. (See figure 1).
Then it is possible to inject neutral gas from the nozzles, if the product is delicate.
Finally, a mechanism pushes the sealing bar to the rubber support to seal the bag.
