Abstract

164,860. Baker & Sons, Ltd., J., Head, R., and Prescott, W. E. March 17, 1920. Cocoa manufacture.-In a process for reducing cocoa, cornflour, :arrowroot, &c., the material is fed to a conical disintegrating-mill whence it is carried bv a current of air into a sifting-device, the material passing through the sieve being carried off for use while the tailings are ground and returned to the disintegrator. In the arrangement shown, the material passes from a breaker a, such as that described in Specification 155,320, [Class 59, Grinding, crushing, &c.], to a worm conveyer b and elevator d which deliver it to a conical disintegrating mill h, such as that described in Specification 153,332, [Class 59, Grinding, crushing, &c.]. A fan in a casing i attached to the mill h produces a blast of air which carries the material into a sieve k in which rotate beaters n. The materials passing through the sieve k are carried away by a shoot m, while the tailings pass by a shoot p to grinding rolls q, of granite or chilled iron, and thence to the conveyer b.
