Abstract

Abstract 536,110. Malting. SEARLE, R., and BRIGINSHAW, F. F. Dec. 14, 1939, Nos. 32227/39 and 17635/40. [Class 14 (ii)] Air of different conditions of humidity and temperature is supplied to the different sections of a malting floor either by the use of separate conditioning plant for the air for each section, or of a main conditioning plant with temperature-regulating and humidifying devices in ducts for each section ; or by conditioning the air suitably for passage over the germinating section where it becomes warmed and its humidity reduced suitably for passage over the couch and withering sections. Air from the conditioning plant c, d, Fig. 1, is passed through a duct e and distributing duct f, to the centre of the germinating section 3, 4 and is withdrawn by a duct i at the end of the withering section, a duct g at the beginning of the couch section and a duct h at the end of the germinating section to a common duct k from which it is returned by a fan F, Fig. 3, to the conditioning plant. The refrigerator d of the conditioning plant is cut out of action by cutting off the power by a thermostat controlled by a wet bulb thermometer x in the open air, and the operation is regulated by a thermostat w in the duct e. The supply of external air to the circuit is controlled by dampers o, p, q in the connection between the ducts, regulated by motors r<SP>1</SP>, r<SP>2</SP>, r<SP>3</SP> the supply of power to which is controlled by a thermostat s having its tube r projecting into the duct e. Specification 523,975, [Group XXIX] is referred to.
