Juice concentration using juice electrolysis generated by solar cells of solar panel

Abstract

Juice concentrates are made by extracting water from freshly squeezed juice. Extracting water from fresh juice today is done by evaporation, freezing of the water, or using diaphragms. During evaporating, freshly squeezed juice is heated in a vacuum below the boiling point to preserve all its beneficial substances. When water freezes, it is removed by cold. When using diaphragms, freshly squeezed juice is passed through a membrane with tiny cells, as a result of which water penetrates through the membrane, and large molecules of freshly squeezed juice concentrate are deposited on the membrane. All these methods of concentrating freshly squeezed juice require large economic costs. The article presents the concentration of fresh juice, using electrolysis of the aqueous component of fresh juice, generated by direct electric current from a solar cell of a solar panel, leading to the formation of negatively charged microdispersed electrolytic hydrogen bubbles and the production of high-quality fresh juice concentrate by flotation of microsolid components of fresh juice with these bubbles. In the process of freshly squeezed juice concentration, water is not removed from the juice, but itself ensures that a high-quality foamy juice concentrate is obtained in an electroflotator-concentrator simply, quickly, and economically (without the cost of electricity).
