Abstract: An improved condenser system for condensing vapor containing liquid or solid particles to minimize contamination of the condenser system by such particles and to increase the efficiency of liquid processing systems, including extracting particles from the vapor producing processing and cool down of the liquid and returning the particles to the processing container without fouling the condenser system or losing product.

Abstract: An improved condenser system for condensing the by-product of resin cooking processes to minimize contamination of the condenser system by entrained liquid resin particles and to increase the efficiency of resin processing systems, including means for efficiently extracting particles from the vapor produced during processing and cool-down of the liquid and returning said particles to the processing container without fouling the condenser system or losing product. The system also includes design improvements and operation improvements for increasing the efficiency, safety and reliability of the condenser system used in the process of cooling and controlling the processing container.
