hosing 12 a peristaltic pump is a type of positive displacement pump wherein a rotor with a number of rollers shoes wipers or lobes are used to compress flexible tubing as the rotor turns the part of the tube under compression is pinched closed thus forcing the fluid to be pumped to move through the tube additionally as the tube opens to its natural state fluid flow is induced into the pump while other conventional types of pumps can be used a peristaltic pump is used in the enhancement device of the present invention because it will eliminate cross contamination of the enhancement liquid with exposed pump components typically found in other forms of positive displacement or rotary pumps two or more liquid enhancers can be mixed within the liquid mixing container 10 using any conventional technology such as a magnetic stirrer so long as there is no cross contamination between the mixer components and the liquid enhancers liquid enhancers can be maintained at room temperature or heated within the pail heater 14 shown in fig3 the pail heater utilizes any common heating technology such as an electric hot plate the specific amount and type of dry enhancer to be used as determined by the ofc is measured and weighed using the digital scale 2 the kibbles liquid enhancer and or dry enhancer are then placed into the tumbler 3 and rotated for an amount of time sufficient to mix all of the ingredients if necessary to provide sufficient coating of the kibbles the liquid enhancers can be sprayed onto the kibbles utilizing any conventional means such as spray nozzles the enhanced pet food is then emptied from the tumbler 3 using the funnel 7 into the pet food bag.
