SELECTION OF OPTIMAL CONDITIONS FOR THE DRYING PROCESS OF AN AQUEOUS EXTRACT FROM THE AERIAL PART OF SCUTELLARIA ADENOSTEGIA

In order to establish optimal drying modes for an aqueous extract from the aboveground part of Scutellaria adenostegia, the following parameters were studied: solution concentration; solution feed rate; temperature of the drying agent at the inlet and outlet; pressure when the solution is fed into the drying chamber. It was found that in order to obtain a dry extract from the aboveground part of Scutellaria adenostegia, antihypoxic action, an aqueous extract obtained with water at a temperature of 60 ° C must be concentrated to a content of 15% of dry substances and dried in a spray dryer of the nozzle type at the temperature of the drying agent at the inlet – 180 °C, outlet – 80 °C, the feed of the solution at 5 l/h *m3 and at a pressure of 0.2 MPa. This mode provides an output of 17% dry extract.
