<p>A fertilizer composition which includes an organic manure material, carbohydrate material and water wherein the moisture content of composition is less than 20 % by weight and the said composition has a fibre content of from 10 % to 70 % by dry weight. Also disclosed is a method of making the above composition and an apparatus for manufacturing it. In the figure the illustrated apparatus includes a tip hopper (10) for receiving manure, carbohydrate and fibre of required. From the base of the hopper (10) the raw materials are conveyed by a conveyor (11) to a clod breaker (12). From the clod breaker (12) a second conveyor (13) conveys the material through a sieve (14) which in turn feeds the sieved material to a holding bin (15) via a bucket elevator (16). From the holding bin (15) the material is conveyed to a ribbon mixer (17) where water, adjusting fibre and any other required additives are added during the mixing process. From the mixer (17) the mixture is conveyed via a screw conveyor (21) to a feed conveyor (22) and is thence conveyed into the drying chamber of a horizontal rotating dehydrator (23). A dehydrator outlet (26) is provided at which the dehydrated product material is screwed out of the drum (23) to be thence conveyed by conveyor (27). The material is then screened through a multi-deck screen (30) and is bagged directly to bulker bags (31) ready for transport.</p> |
