Currently,
we are passing through a very complicated time frame. Most of world population
is suffering from food deficiency and a lesser wasting the food for various
reasons. As we know uncertainty climate, improper availability of land, less
human resource and after all materialistic mentality are some factors for
farming. But we badly need that. Even after harvesting them we are not properly
use them and according to a study the cost of approximately US$ 1 trillion food
are being wasted every year. The time is to think how to distribute or preserve
these foods for a long time. This is so viable to erase the dissimilarities
from our society.
In
order to preserve the food or to increase its longevity freeze drying
technology has emerged as the best one. In some cases, certain types of
chemicals can increase that but its side effect causes numerous health issues.
We
all know that, from a long period of time drying process has been regarded as
the best way to preserve agricultural products. Now scientists have developed
that process named freeze drying technology or popularly known as
“lyophilization”. This process first takes away water or moisture from
products. As we know, water decreases the possibilities of sustainability, so
its first step starts from get rid from water. Then freeze them and placed into
vacuum. In this state, ice changed directly to vapor without becoming liquid.
As a result, absence of water makes those food products more sustainable. After
completion this process, we can found food product as light in weight and can
be placed more in little space. Whenever we want to use them just adding water
can return their old state without changing original flavors, color and
nutrition structure.
This
complex process will be eased by lyophilizer equipment. According
to your need these are available in various sizes. One middle size freeze dryer
will let you use 25-100 square meters shelf area and it has ice capacity of
500-2,000 kg in one batch. The most remarkable thing is that, these models use
radiation mode to heat. In these machines, trays are placed on the trolleys and
carefully moved to the chambers for this reason there is no contact with
themselves. This radiation procedure is suited for loose products such as
vegetables with leaves and fruits.
