4).Optimal parameters
Vacuum time should be determined according to the number or size of the vacuum
chamber and the volume of the material. usually, the vacuum function can be set at
between 20 and 40 seconds. If the degree of vacuum is not lower than 0.06Mpa and
then began sealing, the sealing function may not be completed properly.
special packaging for the product may be appropriate to extend the vacuum time.
For example, a relatively high moisture content of the packaging, and other liquids.
22
inflatable function (if have) parameters to be set according to the actual situation.
If the inflatable too much, vacuum lid opens automatically, the program will
automatically terminate.
If Inflatable excessive vacuum reaches higher than 0.06Mpa and begin to seal, the
sealing function may not be completed properly.
sealing function parameters can be set between 1-3 seconds.
If the bags are exceptionally thick or very thin, the temperature can be adjusted to
select high-grade or low-grade.
Note: If the sealing time parameter is too long, the temperature of the heating
plate will be a sharp rise, which will greatly shorten the heating plate and silicone
life.
sealing function parameters have a great impact on the sealing quality, need to
slowly adjust from low to high.
cooling function parameters according to the thickness of the case of the bag
disposed between 1-3 seconds.
5). For packaging liquid products
Machine can be used for packaging liquid products, such as soups, sauces, etc.,
when the packaging of such products, pay attention to spillage.
Liquid will arrive boiling point when the temperature is higher or it reaches a low
pressure, the high temperature of the liquid product will soon reach boiling point
when packed and thus the degree of vacuum may be lower.
We recommend to cool the liquid products before packing to ensure the best
vacuum effect of the product.
6.the best packaging
use the correct style and good quality vacuum bag.
pocket to leave enough space at least 30mm.
