The present invention relates to a roll film shredding device, and more specifically to a roll film shredding device which rapidly and effectively shreds a long object rolled up into a roll shape, and in particular twists and crumples an object and then performs a shredding operation, thereby effectively shredding an object even though the object is thin, flexible and viscid. The roll film shredding device according to the present invention includes a support frame; an object-to-be-shredded introducing member coupled to the support frame; an object-to-be-shredded twisting unit rotatably installed to the object-to-be-shredded introducing member and performing a twisting operation for an object to be shredded; a rotary driver driving the object-to-be-shredded twisting unit to rotate and perform the twisting operation; and a cutter cutting the object twisted by the object-to-be-shredded twisting unit.

A milling system for milling an edible input material into an edible product configuration meeting a product specification includes a plurality of mills arranged in parallel and connected by recycle loops. A measurement system is provided for measuring attributes of the mills and attributes of the edible input material upstream and downstream of the mills. A continuously self-learning control system is provided for performing operations based on a continuously self-learning algorithm. The operations include processing measurement data of the measurement system to control the mills while maximizing particle sizes in the system, and receiving an operator selection identifying the edible input material to be milled and the edible product configuration to be produced by the milling system. The control system initializes and operates the mills based on an initial control model of the milling system associated with the selection, and continuously updates the control model and mill settings.
