Freeze Dryer Food Fruit Vacuum Freeze Drying Machine Freeze Dryer
Equipment for food flower candy soup
vacuum freeze drying is the removal of water or other solvents from
the frozen samples. During the whole drying process, the sample is
in liquid state and the temperature is generally lower than -10.
The purpose of vacuum freeze drying is to restore the original
characteristics of the sample after rehydration.
Because the drying process is carried out at low temperature, it
can be used for some materials such as proteins, which are easy to
be denatured at high temperature, and can ensure that the
properties of other compounds will not change.
Most of the biological products, such as tissues, tissue extracts,
bacteria, vaccines and serum, were changed into dry samples by
vacuum freeze-drying. Vacuum freeze drying is the most gentle
process to preserve the biochemical properties of sensitive tissue
or other tissues. It is also the best method for drying inorganic
materials, such as nano particles, because the surface area of
particles is almost unchanged.
Product application
Vacuum freeze drying technology, also known as sublimation drying,
is a method of pre-freezing water-containing substances and
sublimating the water under vacuum. The original biological and
chemical properties of freeze-dried products remain basically
unchanged and are easy to store for a long time. After adding
water, it can be restored to the state before freeze-drying and
maintain its original biochemical characteristics. Therefore,
vacuum freeze-drying technology is widely used in medicine, food,
chemical industry, biological products and other
fields.Freeze-dried food can be stored for up to 25 years.
Freeze-dried food is ideal for home storage.
The samples with high acid or solvent content can not be dried in
the absence of special protection (if necessary, please contact the
service department), otherwise the freeze dryer may be corroded.
When drying containing azide should pay more attention to it,
because with copper or other non ferrous metal reaction will
explode.

Attentions
- Must use a grounded power outlet.
- Working environment temperature≤32℃, the humidity≤80%.
- After drying finished, open the vent valve to inflate air at first,
then close the vacuum pump to prevent sample contaminated by the
pump oil. If a sudden power outage, open the vent valve
immediately, and take out the samples as soon as possible, properly
stored.
- Keep the seal ring clean, and cannot Scrub with organic solvents.
- Replace the vacuum pump’s oil after working 100 hours, check and
maintenance the pump regularly.
- Do not frequently switch power supply and refrigerator, If the
refrigerator is shut down caused by operation, at least three
minutes to wait, and then restart the refrigerator
Product details
Installation step
(1)Open the package, check the components according to the packing
list;
(2)Fill the pump’s oil into pump to the middle of the level guide.
Remark: Please using required oil type;
(3)Connect the pipe between pump and dryer by connectors. One side
is fixed on pump’s air inlet, the other side is fixed on dryer’s
vacuum outlet;
(4)Connect the pump’s power plug into dryer’s vacuum pump power
outlet;
(5)Connect the power wire to dryer’s main power outlet, other side
connect to power supply(with ground wire );
(6)Turn on the switch, test step by step according to the
instructions. When all the technical data are satisfy (including
vacuum <15Pa, condenser chamber’s temperature <-35℃), the
dryer could be put into usage.
