The grain to be dried is inserted in the apparatus ever\- 10 or 20 minu-tes, and spread in a uniform layer of 3 to 4 ^j^ inches thickness on the up-per apron, from which it descends, passing successively through the othersto the lower apron, and on reaching the latter is deprived of its moisture. F.\IU,I EXGIXEERIXG II59 From this lower apron the dr\ grain is discharged automatically on-to the ground, after being gradually recooled by means of the cold airdrawn in from without through the suction fan D or the tube x. O i. The advantages possessed bj the \asino drier may be summed upas follows: Il6o FARM HXCIXHICKIXC, i) Machine occupying very little floor space, the portable type with9 aprons examined by the writer weighed. 1102 lbs. and measured : length18 ft., width 8 V4 ft., height 10 ft. 2) Simplicity and reliability of the apron tipping mechanism. 3) Great facility in altering the path and temperature of the airused for drying, according to the kind of grain to be dried. 4) Possibility of carrying out very energetic dr>ing by always pass-ing dry air through. 5) High efficiency. 6) I^imited fuel and power consumption (hardly more than i HP). 7) Little labour required : 1 workman to feed the machine and Ito look after the discharge. The output of this drier of course depends upon the degree of drynessrequired. The makers assume that in order to dry paddy which is notover-wet it will suffice to pass it through the machine twice for 15
