Abstract: An air-treating apparatus for dispensing a volatilizable material, such as air freshener fragrance, into the atmosphere of an enclosed area. The apparatus includes a housing and a reservoir of the volatilizable material therein, and also includes a multiple-configured air flow path arrangement which enables air-flow through the apparatus in multiple configurations. The apparatus enables use of the consistent delivery rates of a volatilizable material producing a more consistent delivery rate than normally achieved with such devices.

Abstract: A vegetable oil process and assembly is disclosed for extracting oil from an oil bearing material such as soybean, corn and the like. The process comprises adding at least one reagent to the oil bearing material to form a slurry mixture. The slurry is heated at a preselected temperature for a preselected period of time preferably under a partial vacuum. This processing reduces the phospholipid and trace metal content in the oil extracted from the oil heating material. The oil product produced is light in color, shows no turbidity and exhibits minimal amount of phosphorus, calcium, magnesium and iron. The oil is ready for physical refining.

Abstract: A vegetable oil process and assembly is disclosed for extracting oil from an oil bearing material such as soybean, corn and the like. The process comprises adding at least one reagent and an oil of preferably the same type as will be extracted from the oil bearing material to the oil bearing material to form a slurry mixture. The slurry is heated at a preselected temperature for a preselected period of time preferably under a partial vacuum. This processing reduces the phospholipid and trace metal content in the oil extracted from the oil bearing material. The oil product produced is light in color, shows no turbidity and exhibits a minimal amount of phosphorus, calcium, magnesium and iron. The oil is ready for physical refining.

Abstract: A rendering system and method is provided for the rendering of organic materials into its major components comprising water, fat and solid proteins. The process involves mixing additional fat with the raw material to form a pumpable slurry including fat and water emulsions. The slurry is treated to break the emulsions and insolubilize the protein solids wherein the fat becomes a continuous phase fat in the slurry and the water becomes a continuous phase water. The treating comprises adding fat to the raw material having a temperature within the range of 140.degree. F. to 270.degree. F. in an amount such that the ratio of added fat to the dry defatted solids of the slurry is in the range of 4 to 1 to 6 to 1, respectively. The treating further includes partially drying the slurry such that at least 15 percent by weight of water as measured as a percentage of total water and defatted solids remains with the solids which discharge from the partial drying step as part of the partially dried slurry.

Abstract: An improved rendering process and system including the use of both a slurry evaporator and cooker. Renderable material is ground and mixed with oil to form a slurry which is then cooked under vacuum in an evaporator to remove some moisture. The resulting partially dewatered slurry is partially deoiled, and the solids residue resulting from deoiling is cooked in a cooker to remove additional moisture. The hot vapors generated by cooking the material in the cooker are used in the steam jacket of the evaporator. Preferably the dewatered solids residue from the cooker is further deoiled.
