  • Publication number: 20250388984
    Abstract: A system for converting cellulosic feedstock to sugar is disclosed and has a reactor chamber configured receive the cellulosic feedstock, a crusher assembly configured to receive the cellulose feedstock wherein the crusher assembly is configured to grind the mixture under pressure to induce a reaction between the cellulosic feedstock and a natural occurring griding element in the feedstock to produce a grinded mixture and sugar, wherein the crusher assembly comprises rollers.

  • Publication number: 20250223310
    Abstract: A system for converting cellulosic feedstock to sugar is provided. The system comprises a biomass hopper configured to accept raw material, a conveying tube with a conveying screw configured to separate and transport the raw material, a product heater proximate the conveying screw tube, a drop chute in communication with the conveying screw, and a crusher assembly configured to receive the raw material and defining a reaction zone, grind raw material under pressure to induce a solid-solid chemical reaction to produce the sugar, wherein the crusher assembly comprises a pair of rollers configured to crush the raw material therebetween.

  • Patent number: 5935536
    Abstract: Apparatus and method for reclaiming expanded synthetic resin wastes in a form suitable for subsequent injection molding. The apparatus includes a tank containing a solvent having a pump for pumping dissolved resin wastes to an evaporator. The evaporator comprises an endless belt on which dissolved resin waste is deposited and precipitates in the form of a thin film. A heater is disposed below the belt to expedite separation of solute and solvent by evaporation. A blower disposed within a housing enclosing the endless belt establishes air circulation over the belt, further promoting evaporation. The thin film is wound on a roller and subjected to a heated roller to fuse the many thin film strata into a solid, generally cylindrical mass. The solid mass is then comminuted by a granulator. Evaporated solvent is recovered in a condenser and is reused.

  • Patent number: 5891403
    Abstract: The present invention features a portable waste disposal unit designed to receive expanded polystyrene or similar polymeric waste. Waste is loaded into a waste reception chamber via a loading door. Once the loading door is closed and locked, a mechanical ram forces the waste charge downward into a removable tank containing a layer of a solvent such as perchloroethylene and an upper layer of water. The waste is dissolved in the solvent and stored until the tank is either removed or drained and the contents shipped to an appropriate waste recovery facility. The small size of the portable waste disposal unit makes it ideal for location near the source of the waste to be recycled. Significant compacting of wastes such as expanded polystyrene may be realized by dissolving the waste in a solvent such as perchloroethylene. In addition, the first step of a recycling process is effectively accomplished within the inventive unit.
