Straw/fodder conversion apparatus comprising a sealable bin (10) which can receive straw to be heated in an ammonia laden atmosphere, wherein the ammonia atmosphere is fed to the bin from an expansion tank (18) external to the bin, into which ammonia from a liquefied source is allowed to expand and boil as it warms under the influence of the environmental temperature, generating an ammonia atmosphere which expands naturally through a connecting duct (24) into the bin interior. Heating is preferably provided by a fluid circulating system (28) which includes a duct (38) passing through the expansion tank (18) to enable supplementary heating of the ammonia in the tank in cold weather conditions. <IMAGE> |
