Cocoa paste conversion to chocolate - in thin films on heated deflection compensated rolls

摘要

A granular crystallisable paste is converted to a product with a fine and homogeneous size consisting, specially of cocoa paste to chocolate paste, by roasting in a thin layer. This is applied by a spreader roll to an internally heated roll with a shell rotating around a stationary core. The core includes hydraulic plungers which are applied to the shell and compensate for any deflection. Process does not require highly skilled personnel. The equipment is less costly and takes up less floor space. The thin film results in short diffusion and thermal paths.
