The present invention relates to a water drying control system for refined cotton. The system comprises a pressing machine and a heat exchanger, a back end part of the pressing machine is provided with a discharge opening, and the system further comprises a control box, a main flap valve, a main drying pipe, a first drying cup, a second drying cup, a first cyclone separator, a first flap valve, a first draught fan, a third drying cup, a fourth drying cup, a second cyclone separator, a second flap valve, a second draught fan, a first infrared ray moisture transducer, a second infrared ray moisture transducer and a third infrared ray moisture transducer. Hot air can be supplemented to change the drying intensity and control the moisture content of the refined cotton of each stage in a reasonable scope, so as to effectively increase the performance.

According to one embodiment, a liquid removal apparatus is configured to remove a liquid by irradiating a laser beam on the liquid. The liquid is adhered to a surface of a member. The apparatus includes a laser light source, and an energy controller. The energy controller is configured to unevenly distribute an energy intensity at an irradiation surface by splitting, into a plurality of laser beams, a laser beam emitted from the laser light source and by overlaying a portion of the split plurality of laser beams at an irradiation position where the liquid is adhered.

A waste management system ad method for processing and reusing organic waste such as food, green compost, and the like. The waste is delivered from a shredder to three sequential augers, each having a rotating shaft and a helically-wound blade spiraling therealong. The blades of the augers compress the waste and extract liquid therefrom to be drained into a tank for subsequent use as a fuel or a fertilizer. The remaining organic waste is then heated and dried in a dual drum dryer. From the dryer, the waste is delivered to a pelletizer having an apertured shaping plate extending thereacross through which the waste is pushed and shaped into solid pellets. The hot and dry pellets are cooled within a dual drum cooler. From the cooler, the organic waste pellets are collected, packaged and distributed.

Disclosed is an apparatus for drying a material, the apparatus including: an air-delivery enclosure with an air inlet and an air outlet through which forced air is directed toward the material; and an ultrasonic transducer connected to the air outlet of the air-delivery enclosure, the ultrasonic transducer including: a first inner surface; a second inner surface, the second inner surface facing the first inner surface, the first inner surface and the second inner surface defining an airflow path through the ultrasonic transducer; a first groove defined in a first inner surface, the first groove including a first flat portion; and a second groove defined in a second inner surface, the second groove including a second flat portion.

A system and method for post-processing of polymeric items having a liquid component and a predetermined heat deflection temperature is provided. The system includes a washing station to spray water at elevated temperature and pressure on the items while maintaining the temperature of the item below the heat deflection temperature. Then using a water distillation system to separate the water from the water mixed with the liquid polymer component by evaporating the water using heating coils with surface that is not conducive to adhesion of the liquid polymer component and then condense the water vapor into liquid water. The system may further include a spin station to separate the liquid polymer component by spinning the item. The system may further include one or more processing stations to rinse the item, dry the item, cure the item, remove the item from a tray to which the item may be attached and clean trays after removing the item. A conveyor system may be used to automate the post-processing of the items.

The disclosure provides a method of forming an acoustical panel base mat, including providing a green board including an alkyl ether sulfate surfactant, wherein the green board includes from about 10 to about 40 wt. % solids, and dewatering the green board slurry to form a dewatered green board, wherein the dewatering comprises supplying hot air and applying a vacuum to the green board.
