1,020,364. Hay &c. pellets. MASSEYFERGUSON SERVICES N.V. Nov. 6, 1962 [Nov. 20, 1961], No. 41890/62. Heading A2B. In a method for forming pellets of cut forage crops, notably hay, wherein the cut crop is picked up and chopped, is entrained in an airstream, is so delivered to a pelletforming mechanism having pellet-forming cells, and the hay against the entries to these cells is urged by successive applications of pressure through the cells and is so compacted, the portion of the crop picked up but not formed into pellets is' collected and redelivered to mix with the crop entering the cells. Moisture, containing if desired binding agents, dietary supplements or preservatives, may be incorporated in the chopped crop. The apparatus includes a pellet-forming mechanism (Figs. 5 and 8, not shown), a delivery duct (Fig. 2, not shown), means to deliver hay or the like entrapped in an air stream to the pellet-forming mechanism, and a return duct (Fig. 2, not shown) for returning air, together with hay which has remained undelivered, back to the delivery duct. The discharge means for the formed pellets may be associated with means (Fig. 10, not shown) for collecting particles detached from pellets and returning such particles to the hay or the like being delivered to the pellet-forming mechanism. |
