Applications
Storage, reloading and packaging
Utilizing the modified ambient (inert gas environment)
method in the food processing ensures a multiply extended products
shelf life, unaffected products appearance, and the improved flavor
properties. The functional inert gas is a low-reactive and partially
soluble in products and in packaging materials atmospheric component —
nitrogen. GRASYS nitrogen plants help preserve foodstuff from oxidation processes,
mould dispersal, generation of micro germs and insect pests.
The adoption of GRASYS units designed specifically
for the tasks of alimentary products keep-storing, end products
inert-environment packing, and the provision of a controllable
environment for vegetable store cellars will inevitably relieve you from
a load of problems, which are:
- Oxidation. Oxidants, in particular oxygen, intensively affect non-saturated fatty
acids making such products as butter, margarine, nuts and potato
chips generate unpleasant odors. By the majority of perishable
products the oxidation process can be delayed through the reduction
of the in-package oxygen concentration even below 2%. GRASYS
nitrogen plants will provide you with a 99.9% purity nitrogen
solution.
- Mold dispersal. Mold is one of the major deterioration
drivers in terms of alimentary products. Package inflation with
a high purity nitrogen (up to 98–99.9%) can reliably
block up the proliferation of mold fungi.
- Generation of micro germs. Generation of micro germs, particularly
bacteria, turn foodstuffs into poisonous substances. This process can be stopped
or retarded by the injection of nitrogen & carbon dioxide
mixture into foodstuff package.
- Insect pest. Inert environment is baleful for most types of insects,
and consequently, proves a good protection from insect pest.
Summing up, storage and packing in a modified
environment can help extend product best-before-use life, preserve
its flavor properties, thus, dramatically increasing its competitive
value. Western countries were quick to adopt and are currently
enjoying the modified environment technique for storing and packing
such alimentary products as butter, cheese, juices, beverage, yogurts,
coffee, nuts, potato chips and the number of other products.
The design and operation of the plants
is based on the most advanced hollow-fiber technology of the fifth
generation imparting to them a range of unique advantages:
- Cost efficiency. The cost of nitrogen
produced with the company plans is ten-time less
expensive than that of the nitrogen supplied by the cryogen
or absorbance technologies or ready-bottled nitrogen.
- Dependability. The underlying principle
of company made systems is their outmost simplicity. The units
accommodate no moving components. When the liquefied air is forced
through the membrane system nitrogen is separated from other gases
to be delivered directly to the storage area with the controlled
atmosphere.
- Adjustability. The nitrogen plants
allow for the adjustment of the nitrogen purity up to 99.99 %,
and the output capacity up to 5000 Nm3/hr. Once
recovered, the nitrogen requires no oxygen additions due to its enhanced
purity.
- Designed convenience. Membrane nitrogen
units are fully automated devices and require no personnel
to operate them. The start-up and cut-off periods
last for just a few minutes.
