ANIMAL FOOD PRODUCT AND METHOD AND APPARATUS THEREFOR

A trub, hops and yeast mix (THYM), a problematic brewery side stream, has high amounts of antimicrobial hop metabolites and positive nutritional effects. Trub, hops and yeast wastes from fermenters, whirlpools, mash tuns, kettles, hopbacks, and grundies with pumps, sanitary piping and storage tanks are combined. Dewatering the mix caused an unexpected improvement in the stability and rheological properties of the THYM, allowing for greater material handling. Dewatering and drying may be by using one or more of filter bags, double drum dryers, rotary dryers, agitated mixing, and flash dryers. A dry product is produced which is suitable for pelletizing and/or packaging. THYM as a feed or supplement can improve weight gain in animals, enhance food flavors, stimulate rumen propionate synthesis, reduce methane production in vitro, increase bovine feed efficiency in vivo, positively alter the gut microbiome.
