CONVECTION DRYERS AND SOVES AND DESDHYDRATATOR
The classification for the dryers is very broad,
however, the most general is given by the
method with which heat transfer is carried out
and the way of elimination of moisture, which
is one of the factors that contributes seriously
to the decomposition of the products, the
design of these simetams of dryers and stoves
is oriented to the drying of all kinds of food,
minerals, among others. For example: grains,
meat, fruits and vegetables, since they have
the necessary characteristics to achieve
optimal drying or cooking of the products .:
a) Convection (dryers in trays or trays, tunnel,
rotary, by
sprinkling, etc.).
b) Conduction (drum dryers, indirect vacuum
dryers with shelves, etc.)
c) Radiation (solar dryers).
In turn, they are subdivided according to the
type of dryer container: trays, drum, tunnel,
spray, etc.
Mixed solar dryer In them the product is
exposed simultaneously to direct solar
radiation and to the air previously heated with
solar energy. They are useful when the area is
insufficient for direct solar drying, with an
adequate circulation of air they can produce a
more uniform drying, their parts
The Solar Collector Which consists of a glass
cover that allows the passage of short wave
solar radiation, an absorbent plate formed of a
uniformly distributed layer of stones that
allows absorbing the short wave radiation by
concentrating it and reflecting it in long wave
radiation. The collector seeks to raise the air
temperature and reduce its humidity.
The drying chamber. It is a closed cabin,
whose dimensions depend on the number of
plants to be dried and the drying process. It
consists of an entrance connected to the exit
of the collector and that allows the entrance of
the flow of hot air, has a system of loading
and unloading of medicinal plants, to control
the process more easily. In the chamber, the
air surrounding the plants (with high
temperature) allows the water contained in
them to be removed. Parts of an indirect solar dryer
Extractor support. It is an isolated duct that allows the
evacuation of the humid air flow from the drying
chamber to the environment. Parts of an indirect solar
dryer Chimene Chamber Collector
STUDY APPROACH
Analysis of the thermal circuit The purpose of this analysis is
to obtain an equivalent resistance (Req) that is the inverse of
the total coefficient of heat losses in a flat plate collector
Energy balance taking into account the heat absorbed, the
useful heat, and the losses in the upper and lower part of the
solar collector with flat plates. The theoretical calculation of
the efficiency of the solar collector of flat plates is executed,
determining the optimum catchment area and the passage
area (air flow), with which the dimensions for the collector
can be optimized (length, width and height) where there is
often a strong loss of heat by convection, conduction and
radiation)
FIRST STAGE: Design of a flat plate solar collector, seeks
to determine the optimum material to be used in the areas of
cover, collector plate, thermal insulation, which are
determined from the solar radiation parameters Incident,
reflection index and coefficient absorption
COMPLEMENTARITY BETWEEN THE SOURCE OF
HEAT AND AN AIR FLOW,
Seeking to reduce the amount of water in
fruits and vegetables, content ranging from 80
to 95% A dehydrator is a device that removes
moisture from food to contribute to its
preservation by more time. Through a source
of heat and an air flow, is responsible for
reducing the amount of water in fruits and
vegetables, content ranging from 80 to 95%
1. Reduction of expenses in your production
process.
2. Less time spent drying the product
compared to the traditional system, which will
allow you to rebound your productivity.
3. Obtaining a quality product with
completely organic characteristics, free of
contaminants by traditional combustion (gas,
diesel or electricity).
4. Use of alternative, clean sources of energy.
5. Being hybrid can be used with equal
efficiency even in winter seasons or in areas
of darkness
6. Conservation of the nutritional conditions
of the product.
7. Low costs for the installation of thermal-
solar equipment, since will use its existing
infrastructure and resources.
