    Equipment solar dehydrator of fruit with aroma recovery system using solar energy, which consists of two sources of heat input (trombo wall and parabolic cylindrical collector), in turn the adaptation of a thermobank to achieve the calorific balance by reducing the high temperatures obtained in parabolic cylindrical collector and/or as a reserve complement of heat energy in hours where the solar radiation is weak or zero (by heat piles, stones). Inside the dehydration chamber there is a duct consisting of three valves which act synchronously to let the moisture of the product pass, condensing it, draining it and finally returning it to the chamber, all forced by a centrifugal fan, thus avoiding the loss of the aroma of the product (fruit) and other organoleptic properties. The temperature and humidity monitoring is by means of temperature and humidity sensors provided with current by solar panels. (Machine-translation by Google Translate, not legally binding)

    [0002] SOLAR FRUIT DEHYDRATOR EQUIPMENT, WITH RECOVERY SYSTEM
    [0003]
    [0004] TECHNICAL SECTOR
    [0005]
    [0006] The present invention is included within the sector of the transformative industry of agricultural products and in turn in the renewable energy sector.
    [0007]
    [0008] BACKGROUND OF THE INVENTION
    [0009]
    [0010] There are multiple food drying equipment but which differ substantially from the present invention.
    [0011]
    [0012] In the following, different fruit dehydration equipment are shown which present certain drawbacks that come to solve the proposed equipment and, common to all the known equipment is that none of them has an aroma recuperator.
    [0013]
    [0014] Patent CN106382810A (it has a system of preheating by traditional solar collector, of low intensity, it does not have aroma recuperator, it is for drying ripico of food).
    [0015]
    [0016] Patent WO2017 / 027813 A1 (it has a configuration of drying trays in a staggered way, however, it has a low calorific energetic acquisition, it does not have an aroma recovery system).
    [0017]
    [0018] Patent CN106403572A (medium and high intensity system by the use of parabolic cylindrical collectors, however, its use is only directed to hours where there is direct solar radiation, the system does not have aroma recuperator).
    [0019]
    [0020] Patent MX 2015008669A (system that uses traditional solar collectors, in turn uses photovoltaic panels as a source of electrical energy for the sensors, the proposed system is of low intensity calorifies, does not have recuperator of to Rome).
    [0021]
    [0022] Patent GR 20150100307 (system by conventional flat solar collector, in turn inside the dehydration chamber is carried out by thermal conduction, however, it is of low calorific power and is only used in hours where there is solar radiation, it does not have recuperator of to Rome).
    [0023]
    [0024] EXPLANATION OF THE INVENTION
    [0025]
    [0026] Dehydrator solar fruit equipment, with aroma recovery system.
    [0027]
    [0028] The design consists of two structural complexes, which in turn raise two objectives, the first to recover the organoleptic properties of the fruit (specifically the aroma), and the second is to provide an efficient calorific contribution from solar energy, this The last one capable of supplying energy warms up during the day when it is cloudy and / or at night.
    [0029] For the system of aroma recuperator (T), it will be able to capture the moisture coming from the fruit, coming from a first outlet pipe (O), passing through valves (Pa) Y (Pb), which will synchronize the passage of humidity, until reaching the condensation process by assisted conventional refrigeration (LL), and drainage (L); the process will be forced by centrifugal fan (K). Secondly, with regard to the efficient calorific contribution, a design of thermal heat bank or "Thermobank" (A) has been incorporated by hand, which allows a heat transfer process by conduction (heat emitted by pipeline). (E) coming from the parabolic capillary collector (J) to the water of the Thermobank (A) for its later conduction through the pipe (D) to the dehydration chamber) allowing to "calibrate" the ideal temperature and at the same time save the calorific energy in some "Heat batteries" (stones) located in the Thermobank, the latter with the objective that the dehydrator work in hours where there is no intensity of solar radiation (night) and / or this cloudy (low intensity of solar radiation), and emit its energy is calorified by the effect of thermal equilibrium (zero law of thermodynamics) with the same destination (dehydration chamber), thus achieving the presence of controlled heat in the product that is in a process of dehydration or constant.

    [0051] PREFERRED EMBODIMENT OF THE INVENTION
    [0052]
    [0053] The solar dehydrator system is equipped with a dehydration chamber, where the product will be housed (fruit) and the process of moisture extraction and the recovery of the organoleptic properties will take place; the camera is initially made of three sides, two sides and a front of wood material and isolated polystyrene expanded, the other front is a wall of stones joined with cement, in turn the outer side painted matt black and additionally joined to a cover of waterproof glass whose side face is inclined to obtain a greater number of incident solar rays and therefore a greenhouse effect; This wall has holes in the top and bottom, which will have the function to establish the calorific flow (by thermosiphon) towards the chamber. Inside the chamber, there are the metal grid trays where the product to be dehydrated will be housed, in the lower part there passes a copper pipe, this being the means of transporting the hot fluid coming from the Thermobank. As external elements to the camera, there is the parabolic cylinder collector, whose focal axis is made of thermally insulated copper pipe, the horizontal parabola is made of stainless steel, accompanied by a system of valves and pump that have the function of increasing the speed of heat transfer. The thermobank is a thermally insulated metal box with expanded polystyrene, inside it is the presence of stones (large volume), this whole system is flooded in water, which will be transported by insulated copper pipe to the dehydration chamber.
    [0054] The humidity obtained in the dehydration chamber will be transported by ducts located in the upper part of it, to the system of aroma recuperator, which consists of a condenser and the drainage system, throughout the system in mention is the presence of Valves, which act in a synchronized manner during the process of solar dehydration, the process is linked to a system forced by centrifugal fan.
