Full Text FIELD OF INVENTION
The present invention relates to a non Convertional energy based

underground stroge device for model rating cold condition at high attitude for

perentation of fresh vegetable undergroundstructure for moderating extreme

cold conditions at . ,

high—altitude for applications such as commercial
storage of fresh vegetables like potattoes

pumpkins, carrots, radish, turnip, beet root etc.

PRIOR ART Tubers have been the main source of nutrition for the
people of high altitude cold arid climates. The people residing at high altitudes remain cutoff for long
durations at a stretch and therefore have no access to farm, sea and products of the temperate zone. Some of
the regions of these extreme cold arid zones like Ladakh, situated at 8000 to 14000 ft above M.S.L., in
India, have to depend on stored foods during the cold
period. During winter, the temperature, in habitable
o areas of Ladakh drops to, as low as {—) 30 C, while
elsewhere in Ladakh the temperature are even lower.
The traditional storage of vegetables at high altitudes is generally by keeping them in a pit of suitable depth and covering them with dry earth.
One of the disadvantages of using the above method is that it is not feasible at commercial levels.

Another disadvantage of the using the above method is that pit once opened has to be evacuated completely due
to cold injuries causing wrinkled skin and other freeze related damage.
Still another disadvantage of the using the above method is that due to the heat of fermentation getting trapped,
the lower layers of vegetables get spoiled early and become unsuitable for human consumption.
Yet another disadvantage of the using the above method is that only a few vegetables like potatoes, radish and
carrot can be stored for a limited period (using from Dec to Feb each year).
Another method of storage of tuber seed at these places is by digging a pit on a steep slope and there—after
covering the seed with gravel and earth, to avoid snow, sleet and precipitation, from seeping into this space.
One of the disadvantages of the using the above method is that the lower placed tuber mass gets crushed due to excessive loading.
Another disadvantage of the using the above method is that. to avoid the above cited drawback, number of
smaller size pits are dug at regular space. The refilling these several pits during sowing season causes
1abour over head.
Still another method of storage of potato in high altitude areas where the duration of winter conditions
is limited to 2—3 months, is that the seeds are stored in pits which are lined with dry leaves and covered
with straw until they sprout.
One of the disadvantage of the using th« above method is that the seeds may not germinate in regular order and the crop thereafter may mature at different periods causing hardship while harvesting.
According to yet another method of storage known in the art, as per US Patent 4,423,680, involves subjecting of
the organic matter to gradual decompression and cooling to freezing or sub—freezing temperature. In this method
biological activity of the organic matter is suspended during storage, retaining cell structure which returns
to fully normal condition on reconstitution.
One of the disadvantage of using the above method is the high cost of installation of decompression apparatus.
Another disadvantage of using the above method is that the adoption of the technique is difficult for the
generally illiterate people residing at high altitudes like Ladakh in India.
Still another disadvantage of using the above method is that not all the tuber products return to their original shine and flavour on reconstitution.
Further disadvantage of using the above method is that this method is not cost-effective for low valve organic
mass.
Yet further disadvantage of using the above method is that the cellular structure of the tissue may require an
additional process of thawing for return and regaining original appearance and consistency.
OBJECTS OF PRESENT INVENTION
The primary object of the present invention is to provide an underground structure for moderating of extreme cold conditions at high altitudes for storage of fresh vegetables such as tubers, onions, pumpkins, carrots, radish, turnip and beet root.
Still another object of the present invention is to provide an underground structure which is cost effective
for moderating of extreme cold conditions at high a11 i tudes-
Further object of the present invention is to provide an underground structure for moderating of extreme cold conditions at high altitudes, which can be constructed with the raw material generally available at high altitudes.
Still further object of the present invention is to provide an underground structure for moderating of
extreme cold conditions at high altitudes which can preserve fresh vegetables over 6 months, without causing

any damage to the stored organic matter.
Vet further object of the present invention is to provide an underground structure for moderating of extreme cold conditions at high altitudes for storage of organic. matter for long duration of over 6 months without loss of capacity to germinate.
Yet further object of the present invention is to provide an underground structure for moderating of
extreme cold conditions at high altitudes, for storage of organic matter/seeds which is cost—effective and can
be easily adopted by local population at high altitudes.
Even further object of the present invention to provide an underground structure which keeps the cellular suitable for mammal use during the entire period of stor age.

DESCRIPTION OF FIGURES
An embodiment of present Invention will now be illustrated with reference to accompanying drawing, which is intended to illustrate the construction of the apparatus but the invention is not intended to be limited to the construction shown in the drawing but also comprises of modifications or equivalents, within the scope of the disclosures herein.
In the accompanying drawing:
Fig.l: shows the structure of the present invention.
BRIEF DESCRIPTION OF THE ACCOMPANYING DRAWINGS
Referring to Fig.l, the structure of the present invention comprises of rectangular box shaped pit below the ground level (1). The pit has upright masonary walls (8) on four sides, while the masonary wall on fourth side of the pit, has a door (4) and a monoeuvrable ventilator (3) with panelled glass shutter and mosquito proofing mesh. The access to the door (4) is by stairs (5). The floor of the pit is a plain earthen ground (10), over which are placed bailies or round wooden logs (6) having for example about 150 mm dia. The jute bags (7) containing fresh potatoes / vegetables are systematically stacked on the bailies (6) in layers and are arranged with sufficient space between the columns of bags to albw circulation of air, heat of fermentation and heat radiations emitted by earthen floor at night so as to maintain moderated temperature within the structure. The
roof (9) is constructed of wooden planks placed side by side without gap and resting on wooden bailies (2) which are also placed side by side. The walls of the pit have a height of for example about 2.2 meters. There is a space preferably to the level as by way of example of about one-fifth of the height of room, which is kept as a clearance between the wooden roof top (2) and the top of the stacked gunny bags (7). The top (9) of the structure, has also preferably a depth equal to about for example one fifth of the height of the structure below the ground level (1) and this depth i.e space between the ground level and the top (9) of the structure is filled with earth. The height of door (4) is preferably for example approximately 55% of the total height of the structure. The rectangular ventilator (3) has preferably height and length in the preferred ratio of for example 2:3 and its height is preferably about 9-10% of the total height of the structure.
It is to be understood that the structure of the present invention is susceptible to modifications, changes and adaptations by those skilled in the art. Such modifications, changes, adaptations are intended to be within the scope of the present invention which is further set forth under the following claims:-
