Abstract

630,153. Coffee. APPAREILS & EVAPORATEURS KESTNER. Jan. 24, 1947, No. 2335. Convention date, Dec. 23, 1946. [A Specification was laid open to inspection under Sect. 91 of the Acts July 24, 1947.] [Class 129] Powdered green unroasted coffee is treated with a solvent to extract fatty aromatic products and is then further extracted with water or vapour. After removal of the solvent, the two extracts are combined and evaporated to dryness. Finally, the product is heated to develop the flavour. The extraction with solvent takes place in an extractor 1, the laden solvent being collected in a vessel 2 and passed to a distilling column 4, where the solvent is removed. The solvent passes by way of a condenser 5 and a retort 6 to a storage vessel 7, ready for further use. The green coffee passes to an infuser 9, where it is infused with water or vapour. Moisture is removed from the coffee in a drier 10 and added to the infusion juices in a storage vessel 11. The juices, after passing through a reheater 13, are concentrated in a concentrator 13a. The latter is connected to a distillation column 14 for the recovery of residual solvent. The two sets of extracts are combined in a vessel 15 and spray-dried in a drying chamber 17. The resultant powder is passed to an autoclave 23, where it is heated with or without the presence of water vapour to develop the flavour.
