Abstract: The present invention provides methods and devices for the preparation and delivery of retention and lubricant agents to ingredients to be pelletized through a forming device such as a pellet mill, extruder or otherwise. Through the features of the present invention, a continuous supply of retention and lubricant agent is prepared and delivered to a forming device, which may be automated based upon calculated or measured need of the retention and lubricant agent. In one embodiment, these and other advantageous features are based upon a unique device configured for automated hydration and delivery of alginate to a forming device based upon one or more conditions of the device, forming device or both.
