vegetable vacuum cooler
the surface of the food
contains a lot of water, due to its higher temperature and water
vapor pressure is also changed. at atmospheric pressure water
evaporation under vacuum is relatively slow, due to resistance to
reduce evaporation speed, so food cooling speed. the food at the
temperature of 35
℃ to 3
℃ about 20min; in the vacuum groove due
to the pressure of uniform, so food precooling homogeneity; cooling
capacity, including loading and unloading time can run two times
per hour; precooling sanitation, no cross contamination.
and not precooling fruits and vegetables compared to, is more suitable
for the long distance trade exports and domestic city arisen
supermarket clean food, clean pollution-free vegetables, wild
vegetables, flowers, edible fungus and preservation process, has a
broad prospect. the practical application proves that, the vacuum
cooling of vegetables, dry surface. fresh green, and directly into
the cold slow blowing cooling of vegetables compared with the
obvious difference.
lettuce in the general environment of shelf for a
period of 3-5 days, vacuum cooling after storage at 1
℃ environment, shelf-life can be
extended to 14 days. can prolong the fresh cut flower vase
period
articles on original senses
and to maintain the quality of the best, but also can improve the
quality of some items, such as the removal of astringency of
litchi
safety, health. high
production efficiency
the body / surface is
smaller than the vegetables, such as cabbage, spinach, leeks and
other leafy vegetables is particularly suitable for the use of
vacuum pre cooling method.
the main characteristics of
coolbest vacuum pre-cooling machine
in 1, the cooling time is
short, only 20~30 minutes, vegetables and can be consistently rapid
cooling to 1~3 degrees c;
2, in the field of orchard
picking operation, can in the first time to eliminate agricultural
and sideline products field heat;
in 3, the vacuum
pre-cooling is clean and sanitary, can inhibit or kill bacteria,
insects and harmful microorganisms, greatly lowering the rate of
decay;
4, even in the rain
harvesting or washed fruits and vegetables, the surface of the
water is in a vacuum state are excluded;
5, configure the brand-name
unit, intelligent automatic control, preventing damage of fruit and
vegetable device, electric open slot door and electric
feed.
by 6, after the pre-cooling
of fruit and vegetable storage transport, and at the end of the
precooling compared its freshness, good taste, high price,
favorable
on sale.
7, convenient operation,
vacuum cooling from restricted packaging, cartons, plastic
packaging products in vacuum cooling,
the cooling speed and
packaging products almost no difference, in the production is very
convenient.
in 8, plc touch screen
control: plc by use of modern large-scale integrated circuit
technology, the strict application of the production process, with
high reliability. from the plc machine circuit, the use of plc
constitutes the control system, and the same scale relay systems,
electrical wiring and switch contacts have been reduced to hundreds
or even thousands of fault, also reduced greatly. in addition, plc
with hardware fault self testing function, failure will give
managers and engineering repair personnel to timely warning
information, to ensure the normal operation of the
system.
