Abstract:
A method for producing organic fertilizer, said method comprising the steps of:injecting a high-velocity air stream and a supply of raw manure into a first cyclonic apparatus comprising an inverted frustoconical chamber, said raw manure having an initial moisture content and an initial live bacteria content, wherein as said raw manure circulates within said first cyclonic apparatus it is progressively pulverized and dehydrated into lighter particles that are drawn to a central low pressure region within said first cyclonic apparatus and expelled upwardly through a transport conduit to an input of a second cyclonic apparatus comprising an inverted frustoconical chamber, said first cyclonic apparatus being physically lower than said input to said second cyclonic apparatus; and receiving substantially all of said lighter particles of said raw manure into said second cyclonic apparatus, said second cyclonic apparatus being substantially larger than said first cyclonic apparatus, whereby the relatively larger size of said second cyclonic apparatus results in a decrease in the air velocity therein, resulting in the settling of substantially all of said lighter particles of said raw manure to a bottom portion of said second cyclonic apparatus as they are further dehydrated, whereby an intermediate organic fertilizer product having a moisture content substantially less than said initial moisture content and a live bacteria content substantially equal to said initial live bacteria content is produced.
