Abstract

307,591. Chaliha, J. P. Feb. 6, 1928. Tea manufacture. - Tea is fired or treated preparatory to withering in a chamber under reduced pressure at a temperature of 160‹-210‹ F., e.g. at 180‹ F. or at 200‹ F. under 15 or 23.5 inches of mercury pressure respectively and fermented in a cool moist draught. The air and moisture are sucked out by a pump connected by tubes 6, 7 to the chamber, which is jacketed on four sides and has two opposite air-tight non- jacket doors. Water is circulated through the jacket and through pipes 8 in the chamber. The tea is also fermented in the chamber, cold water being circulated in the jacket. Water is also placed in open receptacles 10 arranged 1 inch below trays carrying tea in the chamber, and with the vacuum pump a cool moist draught is obtained, the doors being open. The tea is placed 1 inch deep in trays T1 - - T6 of perforated metal, wire netting or hessian cloth, resting on ledges 9 perforated to allow air circulation. Mechanical tea spreaders and stirrers may be used.
