A system for processing a stream of livestock feed, the system comprising:

• a pump operatively connected to an additive tank and in fluid communication with a spray nozzle to move liquid additive from the additive tank to the spray nozzle;
• a mix housing defining a mix chamber and a mix chamber opening, the mix chamber opening providing access to the interior of the mix chamber, the mix housing comprising a first end, a midsection, and a second end;
• an actuating device disposed within the mix chamber, the actuating device configured to move the stream of livestock feed from the first end to the second end of the mix housing;
• a spray housing defining a spray chamber and a spray chamber opening, the spray housing coupled to the mix housing between a midsection of the mix housing and a first end of the mix housing, the spray chamber in fluid communication with the mix chamber through the mix chamber opening and the spray chamber opening;
• the spray nozzle configured to spray a fog of liquid additive into the spray chamber, which passes through the spray chamber opening and the mix chamber opening into the mix chamber and deposits onto the stream of livestock feed as it passes through the mix chamber;
• a steam chest comprising a steam chest housing, the steam chest housing in fluid communication with the mix housing;
• and
• a steam chest thermometer configured to measure the temperature within the steam chest housing.
