Abstract: A process for preparing a nutritional supplement includes the steps of mixing animal blood solids, hydrolized poultry feathers and animal offal to create a mixture, adding protease enzyme to the mixture (20), digesting the mixture with protease enzyme (28) and drying the digested mixture (38) in order to reduce the moisture content thereof down to 5-8 weight percent. During processing, the digested mixture is never exposed to temperatures above approximately 83° C. so that the blood and offal are not degraded or denatured and remain intact so as to provide full nutritional benefit.

Abstract: A combined spray and rotary drying apparatus includes a spray dryer having a housing defining a spray drying chamber, an annular inlet and an outlet. A burner and atomizer sprayer are provided in the spray drying chamber. The outlet of the spray drying chamber feeds into a rotary drying drum. A raw material feed chute is also provided for feeding raw material of relatively low moisture content directly to the rotary dryer. Methods of drying a raw material and of processing raw animal parts are also disclosed.

Abstract: A combined compactor and material mover is provided. The compactor and material mover apparatus includes a housing defining a compression zone, a mechanism for dumping waste material into the compression zone, and a mechanism for compacting the waste material in the compression zone and moving the compacted waste material into a refuse storage unit. The apparatus further includes a mechanism, in the form of a cam and cam follower, for operatively connecting the dumping and compacting mechanisms to coordinate operation thereof.
