1 . INTRODUCTION
The economic and social development of the poorest countries is a variable directly linked to the sustainability , accessibility and cost of energy resources . Which are becoming exhausted day by day making evident the need to implement strategies for saving and efficient use of energy . Especially in the third world , where fossil fuel derivatives are normally used , which are at the limit of commercial exploitation , which has resulted in
an accelerated growth in research and use of alternative sources of energy to be implemented in compliance with with the regulation of three components :
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
Estado actual deshidratador COOK AND STOVE economic , ecological and social , seeking that their technological advances drive in a decisive way the economic development of the agricultural , livestock and mining sectors , allowing them to face economic problems associated with unemployment ; through organized processes marketing of low weight products due to the partial or total loss of the amount of water they contain , which allows them to be sold out of season , also bringing as a benefit the elimination of the waste generated in the process .
2 . STATE OF ART
Design and build a variety of dehydrators and dual-function hybrid stoves capable of using alternative energies : solar energy , biogas .
Looking to generate a commercial project in the e-comerse which requires the optimization of prototypes and an adequate projection of production and marketing costs .
The purpose of drying is to reduce the moisture content of a product to achieve longer storage periods . Quality is evaluated by the amount
of physical and biochemical degradations that occur in the food and depends on temperature , drying time and water activity , due to minimal water activity , microorganisms can not proliferate and are stopped most of the chemical and enzymatic reactions of alteration .
3 . GENERAL CHARACTERISTICS OF SOLAR STOVES
container : trays , drum , tunnel , , 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 . https :// sites . google . com / site / hidraulicatymanzo / luis . cespedes @ outlook . es
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
