5. FAQ – ADDITIONAL INFORMATION

Question: How much longer will my products last?

Answer: Typically shelf life of vacuum packed prod-

ucts may be extended three to ve times. It depends,

however, on the type of product, earlier handling,

storage temperature, conditions before and after

packing etc.

Question: What are the advantages of vacuum

packaging my products?

Answer: There are many advantages of vacuum

packing, e.g. longer shelf life, no changes to the

product, no weight loss resulting from evaporation,

easy labelling (date, weight, best before date, pur-

pose), considerable reduction of aerobic bacteria,

easier storage and control of products, reduced

costs thanks to longer storage, possibility of stor-

ing large quantities, excellent appearance of the

vacuum packed product, better protection against

contamination, easier transport of the product,

better appreciation of product quality by customers

and consumers.

Question: How does sealing temperature aect

the sealing of bag?

Answer: Setting sealing temperature (HIGH, MID-

DLE,

LOW) is related to the sealing function, there-

fore if the sealing level is low (1-2 seconds), then

temperature should be set at middle/high level

and if the sealing parameter is high (more than 3-4

seconds), then the temperature setting should be

middle/low. In each case please test the setting on

a bag.

Question: How to select proper vacuum time for

a specic bag and product size?

Answer: The smaller the product is, the longer vacu-

generation time should be set.

Usually 30 seconds is enough to properly pack a 300

product in a small bag (16/23 cm). Moreover, it

is not always necessary to generate high vacuum,

if you want to pack a product without generating

high vacuum, a dozen or so or even a few seconds

of vacuum time will suce. You should always test

your settings and repack the product if necessary.

Question: Can I vacuum–pack liquids/sauces?

Answer: Yes, you can vacuum-pack liquids and sauces.

Question: Can I crop the bag to adjust it to a small

product?

Answer: Yes, you can cut o the open edge of the

bag with scissors or a knife.

Question: If I vacuum package my food products,

will I still need to refrigerate them?

Answer: Yes, vacuum packaging is not a substitute

to refrigeration.

Question: Do I need to heat the machine up before

turning it on?

Answer: In temperature of 18-24°C,

the machine needs max. 3 min after switching on

to be ready for work. If the ambient temperature is

below 18°C, we recommend starting the machine

up 7 minutes after it has been turned on and set-

ting the sealing time at 0 seconds to properly dis-

tribute oil.

Question: What products can be vacuum-packed?

Answer: You can vacuum pack products that are

resistant to vacuum, i.e. any food products, metal

elements, clothing, money etc.

Question: What type of bags should I use for vac-

uum-packing?

Answer: We recommend Victor Vacuum Bags

which are dedicated for our machines. Please con-

tact your distributor or our company.

Question: How often should I replace or replenish

oil?

Answer: Oil should be replaced, i.e. drained after

it turns dark brown (dirty) colour or at least once

every 6 months. Before starting the machine, it is

necessary to ll half of container with oil and then

keep this level by replenishing oil (please check oil

level every month). Oil is delivered with the ma-

chine. We recommend Victor Vacuum Oil.
