Plant stems are confined in an airtight bag (2), which is void of air, after which ammonia is supplied. After a suitable period of time, the stems are removed and can serve as a food substance. The end piece (nozzle) (1) of a tube (6) is applied firmly against the walls of the bag (2) by means of two nuts (11, 12), a seal (13, 14) being placed between these nuts and the wall (2). An elastic sleeve (5) firmly clasps around the tube (6) and an insertion pipe (4) so as to produce a leaktight connection. A fastener (15) applies the sleeve (5) to the tube (6), and gripping-clamp jaws (7, 8) compress, by virtue of elastic strings (10), the sleeve (5) around the pipe (4). This method supplies a uniform food substance with a low percentage of ash and without residual sediment which could be harmful to animals. <IMAGE> |
