DETAILED DESCRIPTION - Flexible solar energy collection system that uses linear parabolic concentrators designed on a small scale, comprises at least one linear parabolic trough comprising: (i) a channel-shaped surface parabolic sectioned into at least two symmetrical parts or panels of equal size, which individually comprises a support frame constructed of metallic material (not restricted to these materials); (ii) a reflector mirror based aluminum foil or a polymeric material mounted on each of the panels described in the previous section and secured by screws, rivets or adhesives; (iii) at least two curved support arches that provide rigidity to the reflective parabolic surface to wind stresses and are distributed longitudinally and located at the rear of the solar collector; (iv) at least three transverse tubular elements joined together with the support ribs, using fasteners such as bolts and threaded bars, the tubular elements provide greater tensile strength to steady the surface geometry dish; (v) a receiver element for concentrated solar radiation, formed by a cylindrical tube made of a metallic material such as copper or stainless steel (not being restricted to these materials) coated with a selective surface to solar radiation and convection losses protected by concentric tube based transparent borosilicate glass; (vi) a heat exchanger system for dehydration product comprising a thermal isolation of the environment, a heat input via a high temperature fluid with the respective output, an array of fans and thermoelectric cells that produce a constant airflow within the chamber; dehydrator transfers its energy to the product by conduction, convection and radiation; and (vii) an electronic control module based solar tracking photovoltaic cells or phototransistors (not restricted to these) which features a solar tracking algorithm embedded in a microprocessor or microcontroller, not restricted to these items, where the system is coupled to an electromechanical actuator which maintains the position of the collector to the sun elevation angle at all times. An INDEPENDENT CLAIM is included for a heat exchanger for high efficiency applications for dehydration of product based on conduction, convection and radiation as primary heat transfer mechanisms, comprising: (a) camera constructed with a metallic material (not limited to these materials) which transfers heat energy from a solar concentrator system coupled to a backup system based on fossil fuels, the thermal energy is delivered to a product which is need to remove a certain percentage of humidity in your physical composition; (b) thermal insulation mineral fiber base, ceramics or polymer, which does not allow the transfer of heat from the chamber to the outside; (c) a coil-shaped pipe leading a high heat transfer fluid into the inside of the heat chamber; (d) an arrangement of two metal plates parallel to each other for thermal energy transferred from a high temperature end of the coil connected to a low temperature plate located at the opposite end; (e) an array of high thermal transfer rods constructed of steel, copper or graphite (not restricted to these materials) interconnecting the two plates parallel to each other; (f) an array of fans operating power based to be lit and causes an air flow from the outside to inwards; (g) a thermoelectric cell array connected to the cold plate heat exchanger and heat sink in contact with the exterior of the dehydrator; and (h) an array of sensors located within the thermal chamber to measure the amount of moisture present and interconnected to an electronic control system which regulates the speed of rotation of the fans.
