TECHNICAL FIELD
The present disclosure relates generally to food preservation device. More particularly,

device, system and method.

BACKGROUND
Post harvest losses of perishable produce like fruits and vegetables is a major concern
in the global food supply chain. Over the years farmers, traders and processing industry
have deployed multiple technologies to reduce post-harvest losses. Large- and small10 scale cold storages is one of the most commonly used methods for food preservation.
However, this method has limitations due to very high capital, operational,
maintenance and supply chain costs. This makes the technology out of reach for small
and marginal farmers who are at the bottom of the value chain and incur maximum
financial losses. Preservation of perishable food by drying is the most ancient process
15 to prevent post-harvest losses. In the modern world many technologies have evolved
for removal of water content from food produce and extending its shelf life up to 12-
24 months. Freeze Drying, Spray Drying, Air Drying, Electrical Oven drying are some
forms of electro-mechanical technologies being widely used in the industry. These
technologies are also capital intensive and out of reach of small and marginal farmers.
20 Farmers in India have depended upon open solar drying mainly for the spices segment
for centuries. From the last 3 decades farmers and women entrepreneurs in DahanuGholvad region of Maharashtra have used open sun drying for the Sapota (Chikoo
Fruit) which ripens on farm and cannot reach the markets. However, there is a lack of
uniformity, shelf life, product quality, taste and texture in this non-standard process
25 which depends on ambient conditions.
There are wide range of experiments that have been done on various available
technologies for improving the product quality and shelf life of Sapota (Chikoo) fruit
and other fruits and vegetables grown in the region. This article is an outcome of these

experiments which has enhanced the efficiency of existing mediums used to lay food
substances inside solar or electric dehydrators. The design principle exhibited in this
article is universal and can be applied to any solar or electrically powered dehydrators
for food or non-food substances. In the various studies conducted on solar energy-based
5 food preservation technologies it was observed that following modes of moisture
removal have been commonly deployed - radiation, convection and conduction. These
traditional modes have been used by humans since ancient times in various
combinations. Advancements in design of solar and electric dehydrators have presented
various means and methods to prevent dust and external matter, retain nutritional
10 content, retain taste, texture and color, reduce process time and so on.
Conventional dehydrators which deploy convection as the primary principle for
extracting moisture from food substances use a “Wire Mesh” or a “Perforated Metal”
tray as the medium to lay food substances inside a dehydrator. These wire mesh or
perforated trays are arranged in a single layer of multiple layers inside the dehydrator
15 depending on the system design. The wire mesh or perforated tray design ensures hot
air (generated by solar or electrical energy) flow generated by a ventilation system
(natural or forced) transmits heat to both the top and bottom of the food substances.
Also, the moisture content that settles down due to gravity gets space to escape from
the bottom of the tray. Convectional dehydrators are however the least efficient design
20 due to heat losses at multiple stages in the process. In these types of dehydrators it takes
18-24 hours to bring down the moisture to less than 10% level due to which the shelf
life of the food substances gets extended to 6-12 months.
Another prior art dehydrators which deploy conduction as the primary principle for
extracting moisture from food substances use a flat metal tray as a medium to lay food
25 substances inside a dehydrator. The flat metal trays absorb the heat (generated by solar
or electrical energy) and transmit it directly to the food substances laid on it. The
moisture content in the food substances starts converting into vapor which is removed
from the dehydrator using natural or forced ventilation. This highly enhances the
efficiency of moisture extraction, and the process time is reduced by 50% compared to
5
convection. The challenge in the conduction method is that the temperature of these
plates cannot be set exactly to the desired limit and if it rises above 60 degrees Celsius
there is a high possibility of loss of nutrients from the food substances. Sugar content
in the food substances can also get caramelized above 60 degrees Celsius and
5 discoloration (blackening) is observed. The design principles of various dehydrators
presented in previous articles speak about enhancing the process through various
techniques to optimize radiation, convection and conduction. The bigger challenge is
however presented by gravity which is not addressed in the earlier designs. It has been
observed that apart from radiation, convection and conduction, gravity plays a major
10 role in removal of water content from the fruits and vegetables. Since the tray surface
is flat, the water content that settles down due to gravity gets accumulated and locked
below the food substance. This accumulation of water below the food substances
adversely impacts the drying process by reducing the temperature of the metal plate.
This accumulated water is locked between the tray surface and the food substance and
15 hence not exposed to direct radiation or convection. Conclusively, convection
principle-based dehydrators use wire mesh or perforated trays to ensure maximum
surface area of the food substance is exposed to the hot air flow. Conduction principles
dryers use a flat metal tray to ensure direct heat transfer, however only 50% of the
surface area is exposed to radiation and convection. Conduction drying is nearly 50%
20 efficient compared to Convection drying in terms of the process time. On flat trays used
in conduction drying water content gets accumulated below the food substances and
reduces process efficiency.
Thus, there is a need for a technical solution that overcomes the aforementioned
problems of conventional dehydrators.

25 In some embodiments of the present disclosure, the plurality of chambers 104a, 104b
and the plurality of metal trays 108a, 108b exhibit a variable size based on size of the
one or more food articles.
In some embodiments of the present disclosure, each metal tray of the plurality of metal
trays 108a, 108b is disposed at an inclination angle ranging from 6 Degrees to 30
11
Degrees that facilitates exertion of gravitational force on water content released by the

from the food substances does not directly come in contact with the food substances on
the lower side of the tray. To prevent this the engravings on the tray are such that water
is obstructed at multiple points. These obstructions slow down the downward flow of
water and ensure direct exposure to radiation and conduction inside the dehydrator for
10 a longer period. This helps the water content to evaporate quickly and eventually the
forced or natural ventilation carries the vapor out from the dehydrator.
In some embodiments of the present disclosure, the one or more food articles are precut as per their properties and placed on the metal surface of the plurality of metal trays
108a, 108b.

of the gravity assisted food preservation device 100, in accordance with an embodiment
of the present disclosure. Each tray of the plurality of metal trays 108a, 108b is
engraved in a mesh structure 302 that facilitates formation of a plurality of micro spaces
and tracks between the one or more food articles. The plurality of micro spaces and the
20 tracks facilitate to guide water content released from the one or more food articles.
Each tray of the plurality of metal trays 108a, 108b is a hollow tray that is filled with
an insulation medium. The insulation medium comprises one of, air and an insulation
material. Each tray of the plurality of trays 108a, 108b comprises (i) a width that is in
a range of 20 millimetres mm to 30 mm, (ii) a length that is in a range of 700 mm to
25 1500 mm, and (iii) a width that is in a range of 700 mm to 1500 mm.
In some embodiments of the present disclosure, the engraved metal surface is engraved
in a unique mesh structure 302 to create multiple micro spaces and tracks between the
food substance that is being preserved and the metal surface. These micro spaces and
tracks ensure that the water content that is released due to gravitational force does not

accumulate below the food substance and reduces the heat in the system. The design
of the engraved metal surface tray is such that there are micro spaces and tracks
between the food substance and the metal surface. The water that settles down due to
gravity does not get locked below the food substance and flows downwards on the tray
5 thereby enhancing the efficiency of the food preservation system.
The gravity assisted food preservation device 100 of the present disclosure is a
balanced combination of ensuring water content that settles down due to gravity is not
locked below the food substances laid for drying inside the dehydrator. The water
content that flows downwards is obstructed at multiple points and its speed is
10 controlled. The slow movement of water ensures there is enough time for exposure to
radiation and conduction. The evaporated water vapor is drawn out from the dehydrator
