SOLAR FRUIT DEHYDRATION EQUIPMENT, WITH AROMA RECOVERY SYSTEM

SECTOR OF THE TECHNIQUE

The present invention is included within the sector of the transformative industry of agricultural products and in turn in the renewable energy sector.

BACKGROUND OF THE INVENTION

There are multiple food drying equipment but they differ substantially from the present invention.

Below, different fruit dehydration equipment is shown that has certain drawbacks that the proposed equipment has to solve and, common to all known equipment, is that none of them has an aroma recuperator.

Patent CN106382810A (it has a preheating system by traditional solar collector, of low intensity, it has no aroma recuperator, it is for the typical food drying).

Patent WO2017 / 027813 A1 (it has a configuration of drying trays in a staggered way, however, it is of low calorific energy acquisition, it does not have an aroma recovery system).

Patent CN106403572A (medium and high intensity system for the use of parabolic cylindrical collectors, however, its use is directed only at times where there is direct solar radiation, the system does not have aroma recuperator).

MX patent 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 calorific intensity, does not have a recovery of smell).

GR 20150100307 patent (conventional flat solar collector system, in turn within the dehydration chamber is carried out by thermal conduction, however, it is of low heat power and is only used in hours where there is solar radiation, it does not have a recovery of smell).

EXPLANATION OF THE INVENTION

Solar fruit dehydrator equipment, with aroma recovery system.

The design consists of two structural complexes, which in turn raise two objectives, the first one to recover the organoleptic properties of the fruit (specifically the aroma), and the second one is to provide an efficient caloric intake from solar energy, this last able to provide heat energy even in hours of the day where it is cloudy and / or night.

Regarding the aroma recovery system (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 moisture, 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 a thermal heat bank or “Thermobank” (A) has been incorporated by hand, which allows a conduction of heat transfer by conduction (heat emitted by pipe) (E) from the parabolic cylindrical collector (J) to the Thermobank water (A) for later conduction through the pipe (D) to the dehydration chamber) allowing “calibrate” the ideal temperature and in turn save the heat energy in some "Heat cells" (stones) located in the Thermobank, the latter with the objective that the dehydrator works in hours where there is no intensity of solar radiation (night) and / or is cloudy (low intensity of solar radiation), and emits its heat energy by thermal equilibrium effect (zero law of thermodynamics) with the same destination (dehydration chamber), thus achieving the presence of controlled heat in the product that is in a constant dehydration process.

PREFERRED EMBODIMENT OF THE INVENTION

The solar dehydrator system is provided with a dehydration chamber, where the product (fruits) will be housed and the process of moisture extraction and recovery of organoleptic properties will occur; The chamber is initially made of three faces, two sides and a front of wood material and in turn insulated with expanded polystyrene, the other front face is a wall of stones joined with cement, in turn the external face painted in matt black and additionally attached to a waterproof glass cover 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, the same ones that will have The function set the heat flow (by thermosiphon) towards the chamber. Inside the chamber, are the metal grid trays where the product to be dehydrated will be housed, in the lower part there is a copper pipe, this being the means of transporting the hot fluid coming from the Thermobank. As external elements to the chamber, there is the parabolic cylindrical manifold, 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 pumps that have the function of increasing the speed of heat transfer. The thermobank is a thermally insulated metal box with expanded polystyrene, within it is the presence of stones (large volume), this entire system is flooded in water, which will be transported by insulated copper pipe to the dehydration chamber.

The humidity obtained in the dehydration chamber will be transported by pipelines located at the top of it, to the aroma recovery system, which consists of a condenser and the drainage system, along the system in question is the presence of valves, which act synchronously during the solar dehydration process, the process is linked to a system forced by centrifugal fan.

Claims (2)

1. Solar fruit dehydrator equipment, with aroma recovery system consisting of: to. a dehydration chamber, characterized by having two metal grid trays inside. b. a heat storage bank, characterized by, comprising a thermally insulated metal box (A) and inside stones as a heat storage element. c. Pipes carrying high-density heat transfer fluid (oil). d. Solenoid valves (Q) and check valve (R). and. Centrifugal fan This equipment is composed of a structural complex of synchronized thermal interactions of both condensation and drainage of moisture extracted from the product; where moisture from the dehydration chamber is redirected through an upper duct (O) to a condensation system assisted by conventional refrigeration, in this first process the valves (Pa) will be open, while (Pb) will be closed , this is how the moisture freezes, after having frozen the moisture, the valves (Pa) will be closed and the valve opened (Pb), and at that same moment the drainage process (L) is opened, giving Instead of extracting moisture from the product, the system continues throughout the course being forced by a centrifugal fan (K). The process will be repeated and synchronized according to the humidity parameters shown in the humidity sensor located in the dehydration chamber (N), avoiding sudden temperature changes, thus avoiding the loss of organoleptic properties of the product. 2. Solar fruit dehydrator equipment, with aroma recovery system according to claim 1, wherein the heat energy production system is a complex equipped with a "Heat Storage Bank" system or in this case called: "Thermobank", all this under the contribution of heat energy from the Sun; the system comprises a thermally insulated metal box (A), and in its interior heat cells (stones, as a heat storage element); inside the Thermobank is The copper pipe from the parabolic cylindrical collector (J) that will be responsible for heating a high-density heat transfer fluid (oil) captured in the geometric focus of the parabola, this fluid when heated will be pumped (B) into the interior of the Thermobank, thus heating the water stored in it, it should be noted that the caloric intake is high enough to also heat the stones and thus have a heat source stored for night dehydration processes or in cloudy environments, where the intensity of solar radiation is zero or minimal respectively; the process will be synchronized by solenoid valves (Q) and check valve (R); once the calorific contribution of the system in question is obtained, it will be transported through the copper pipe (D) to the dehydration chamber (N), once the heat has been insufflated to the chamber, the dehydration process will begin, however It is expected that the hot water through the copper pipe that passes under the trays of the product to provide heat to the fruit, will cool, this is how we direct the output of the copper pipe (C) to the Thermobank for heating, thus following a cyclic protocol under the thermosiphon mode, completing the dehydration process in a synchronized manner. In the chamber is where the calorific contribution and the recovery process of aroma and organoleptic properties is present at all times.
