923,436. Continuous discharge mixers; malt stirrers. J. M. A. MOREL. July 13, 1960 [July 22, 1959; April 25, 1960], No. 24375/60. Class 86. [Also in Groups VI and XIII] Apparatus for the continuous malting of grain, such as barley (see Group VI) comprises a train of carriages 1 to 9, Figs. 1, 2 and 3, running on wheels 14 along rails 15 and moved, one carriage-length per day, through a tunnel having vertical side walls 26, 27. The portion of the tunnel occupied by the carriages 1 to 8 constitutes a malting chamber and the exit portion, occupied by the carriage 9, constitutes a drying chamber. Each carriage has two sheet metal vertical side walls 25 and a perforated, e.g. removable, sheet metal grain-supporting floor 22, which forms the roof of a ventilating compartment 23 having a side opening 24 admitting, successively, air from compartments 28c, 28b, 28a of a ventilating duct lying along the wall 27, and hot air from a compartment 40a thereof. Air, humidified as required, by humidifiers 30c, 30b, 30a, is supplied to the compartments 28c, 28b, 28a by blowers 29c, 29b, 29a. A quantity of grain, equivalent to the desired output of malt per day, is spread, from a hopper 13, on the floor of each carriage before it enters the tunnel. A water-sprinkling trolley 33, connected by flexible pipes 34 to a stationary water pump (not shown) and a grain-turning trolley 32, comprising a motor 35, Fig. 3, driving helical rotary stirrers 37, are moved to and fro in the tunnel along upper rails 31, respectively, over the carriages 1 and 2, in which the grain is steeped, and the carriages 3 to 8, in which most of the germination occurs.
