METHOD AND DEVICE FOR AROMATIZATION OF TEA Russian patent published in 1995 - IPC

FIELD: food industry. SUBSTANCE: method involves extraction of aromatizer by the flow of liquefied extractant gas, separation of extract, mixing it with tea, depositing extracted aromatizer substances on tea upon release of pressure and removal of extractant gaseous phase followed by compression, liquefaction and returning to the working cycle. The method produces quick-brewing tea with improved organoleptic characteristics by preserving native aromatic substances and reducing losses of aromatizer active substances, preventing their destruction and bringing down their carryover with grits. The device for realization of said method comprises a chamber divided by vertical partitions into sections which accommodate two superposed latticed belt conveyors for tea and aromatizer, respectively. Each section of the chamber is divided into two compartments by a horizontal porous partition. Each pipe for connection of branch pipes and discharge of extractant has a compressor and a container for liquid extractant. EFFECT: improved functional and operating characteristics. 3 cl, 1 dwg
