The present invention is an apparatus for spraying a liquid onto pelleted feed, having a hopper with a gate for selectively holding or allowing the dropping of dry pellet feed, a spraying chamber below the hopper with an upper portion to receive the dropping dry pellet feed from the hopper, and a cylindrical lower portion, a cone operably attached to a motor, the cone rotatably disposed within the upper portion of the spraying chamber to direct dry pellet feed received into the upper portion into a single layer of falling feed around a circumference of the lower portion, an enzyme chamber, and a nozzle rotatably disposed within the lower portion to substantially evenly spray an amount of liquid from an enzyme chamber on the single layer of falling feed.
