Abstract: A process for concentrating a maple sap or sweet vegetal water solution is provided. The process comprises collecting the solution in a tank at temperature T1, wherein T1 is between 4° C. and 10° C.; concentrating the solution by means of a reverse osmosis concentrator to produce a high Brix solution of about 15 to about 40 Brix; heating the high Brix solution of about 15 to about 40 Brix to temperature T2, wherein T2 is between 40° C. and 85° C.; and evaporating the high Brix solution by means of a vacuum evaporator at temperature T3 to produce the concentrated product of about 60 to about 70 Brix, wherein T3 is between 55° C. and 80° C. A system for concentrating a maple sap or sweet vegetal water solution is provided, as well as a concentrated product produced by the process of the present invention.

Abstract: An apparatus for increasing gas components in a fluid uses a controller connected to a network and client device for remote control of fluid flow rates, magnet field intensity, and pressure of fluid based on preset parameters. Conductive wire coiled around a magnet fluid treatment device generates a bidirectional magnetic flux to magnetically treat fluid in the conduit at an entry pressure. A variable frequency generator energizes the wire creating magnetic flux lines to pass through the fluid flow conduit. A gas injector receives fluid at the gas injector entry pressure and lowers the gas injector entry pressure of the fluid to a gas injector discharge pressure. A treatment chamber receives the fluid at a treatment chamber entry pressure and lowers the treatment chamber entry pressure to a treatment chamber discharge pressure. The apparatus causes absorption of increased gas component into the fluid by from 10% to at least 500%.
