Claim:
1. A system for cleaning and disinfecting allograft material, the system comprising: a sterile bag having an outer wall configured to withstand compressive forces, a pair of paddle contact sections, and an allograft retaining section separate from the paddle contact sections; a motorized paddle blender having at least two paddles, each having a compressive surface configured to apply compressive forces onto the sterile bag at the pair of paddle contact sections, a motorized portion to actuate the at least two paddles, and a door component configured to hold the sterile bag adjacent the at least two paddles, wherein the at least two paddles and the allograft retaining section are configured to prevent the at least two paddles from compressing the allograft material when the compressive forces are applied onto the sterile bag at the pair of paddle contact sections; and a hollowed port system within each of the at least two paddles, the hollowed port system comprising inflow and outflow ports in fluid communication with a hollow interior of each of the at least two paddles, wherein throughout an actuation cycle of the at least two paddles, temperature-controlled solution constantly flows into each of the inflow ports, across the compressive surfaces of each of the at least two paddles, and out each of the outflow ports, providing a constant flow of the temperature-controlled solution across the compressive surfaces of each of the at least two paddles such that the compressive surfaces resist frictional heating and maintain a constant temperature throughout the actuation cycle; and further comprising an internal screen defining the allograft retaining section at a central location between the pair of paddle contact sections, the central location defined by the internal screen configured to retain the allograft tissue between the pair of paddle contact sections to prevent tissue pummeling and to allow turbulent fluid flow therethrough, wherein the door component, the at least two paddles, the pair of paddle contact sections, and the central location of the allograft retaining section are configured with respect to one another to locate the compressive forces onto the sterile bag on the pair of paddle contact sections at positions away from the central location of the allograft retaining section so as to in turn provide a non-contact area at the central location to prevent application of the compression forces to the allograft material.
