Abstract

Inventia se refera la un procedeu pentru producerea aerului cald necesar în uscatorul industrial de legume si fructe, prin încalzirea cu ajutorul unor panouri (captatoare) solare, caracterizat prin aceea ca prin circuit, aerul încalzit cu ajutorul captatoarelor solare este adus în uscator unde se încarca cu vapori de la produsele supuse uscarii, apoi este evacuat într-o camera de pilverizare prevazuta cu separator de picaturi si tratat cu o solutie pulverizata de sare absorbanta (clorura de litiu sau de calciu) si recirculat în continuare în instalatie fara a-l mai amesteca cu aer proaspat din exterior iar într-un al doilea circuit, solutia salina este introdusa în camera de pulverizare unde intra în contact direct cu aerul, dezumidificîndu-l, apoi este trimisa prin pompare pe o suprafata înclinata expusa radiatiei solare, unde solutia se prelinge în pelicula subtire pe aceasta, eliminînd astfel prin evaporare cantitatea de apa preluata în camere de pulverizare, iar în continuare solutia regenerata este trecuta printr-un schimbator de caldura în contracurent cu solutia pompata din camera de pulverizare si în final solutia ajunsa la temperatura si concentratia initiala revine prin cadere libera într-un bazin de stocare de unde este pompata în camera de pulverizare si ciclul se reia.The invention relates to a process for the production of the hot air required in an industrial dryer for fruit and vegetables by heating with solar panels, characterized in that by the circuit, the air heated by the solar collectors is brought to the dryer where it is charged with vapors from the products to be dried, then discharged into a drip chamber equipped with a drop separator and treated with a spray solution of the absorbent salt (lithium or calcium chloride) and further recirculated to the plant without further mixing with fresh air from the outside, and in a second circuit, the saline solution is introduced into the spray room where it comes into direct contact with the air, dehumidising it, then it is sent by pumping onto a sloping surface exposed to the solar radiation where the solution flows into thin film thereon, thus eliminating by evaporation the amount of water taken up in the spraying chambers, and b the regenerated solution is then passed through a counter-current heat exchanger with the pumped solution in the spray chamber and finally the solution reached the temperature and the initial concentration returns by free fall into a storage tank from where it is pumped into the spraying chamber and the cycle is resumed.
