Process for treating alfalfa and other cellulosic agricultural crops
First Claim
1. A process for enhancing the cellulose digestibility and true protein availability of alfalfa to enhance the alfalfa as a feed for both ruminants and monogastric animals, said process comprising applying ammonia to the alfalfa for a time period less than about one hour at a treatment pressure in the range of about two atmospheres to about forty atmospheres and at a treatment temperature in the range of about 10°
- C. to about 85°
C. to effect alternation of the cellulose-lignin configuration in said alfalfa, thereby increasing the digestibility of the cellulose in the alfalfa and increasing the availability of true protein from the fibers and from within the cell walls of the alfalfa to both ruminants and monogastric animals.

Abstract
Alfalfa and other cellulosic agricultural crops and crop derivatives are treated with ammonia under pressure to increase the true protein availability and the cellulose digestibility. The materials can be evacuated from the reaction vessel either gradually or explosively, with explosive evacuation providing a dust free product having a greener color. The ammonia is recycled by recovering it and recompressing it for reuse in treating an additional quantity of crop.

4. A process for treating alfalfa to enhance the cellulose digestibility and true protein availability to both ruminants and monogastric animals, said process comprising the steps of:
-
applying ammonia to the alfalfa for a time period less than about one hour at a treatment pressure greater than atmospheric pressure and at a predetermined temperature to effect alternation of the cellulose-lignin configuration in said alfalfa, thereby increasing the digestibility of the cellulose in the alfalfa and increasing the availability of true protein from the fibers and from within the cell walls of the alfalfa to both ruminants and monogastric animals; decompressing the alfalfa and ammonia to an intermediate pressure following elapse of said time period, said intermediate pressure being less than the treatment pressure but greater than atmospheric pressure; recovering a substantial portion of the ammonia at said intermediate pressure; recompressing the recovered ammonia to the treatment pressure for treatment of an additional quantity of alfalfa; and decompressing the alfalfa to atmospheric pressure.
