Abstract: A plurality of dough pieces are produced using a rotary dough cutter including a shaft, a plurality of walls extending radially outward from the shaft and a plurality of interior blades extending radially outward from the shaft. The plurality of walls define a plurality of dough cutter molds. The plurality of dough cutter molds include a first dough cutter mold and a second dough cutter mold. A first wall of the plurality of walls defines part of both the first dough cutter mold and the second dough cutter mold. Each of the plurality of interior blades is located in one of the plurality of dough cutter molds. The plurality of dough pieces are cut from a dough sheet with the plurality of walls. The plurality of dough pieces are scored with the plurality of interior blades. After scoring, the plurality of dough pieces are proofed and then frozen.

Abstract: A method of forming a methylol urea prepolymer and a particle coated in with the prepolymer. The method involves providing a source of methylol urea and a source of aldehyde and reacting the urea and the aldehyde in the presence of an excess of urea to form the methylol urea prepolymer. The coated particle is preferably a controlled-release fertilizer particle. The particle is a substrate coated with a substantially uniform coating comprising a total nitrogen content ranging from about 39N to about 42N. The coating includes a low molecular weight methylene urea compounds.

Abstract: A process for the chemical treatment of organic waste materials contaminated with a pathogenic microorganism, such as raw sewage, sewage sludge and other organic waste products, and to the treated organic waste material so obtained, which process comprises: prereacting the organic waste material with a water-soluble methylol compound subject to condensation, such as a methylolurea compound, under alkaline pH conditions; and, thereafter, condensing the methylol compound by establishing an acid pH condition to form a solid waste product comprising a condensation polymer containing methylene bridges and a sterile solid waste material.

Abstract: An apparatus for and a process of treating sludge filter cake and the granular product thereof which comprises reducing the particle size and moisture content of the sludge cake, sterilizing the sludge cake by contacting the sludge cake with an N-methylol-urea solution, reacting the N-methylol-urea solution with the sludge cake at a pH of 3 to 5 while agitating the sludge particles to provide a granular-reaction product, and drying the product to provide a granular, high-nitrogen, odorless fertilizer or animal feed supplement product.
