An ultrasonic-assisted heat press machine, includes a frame, a material tank, an extruder, an ultrasonic wave generator, and a heater. The material tank is disposed on the frame and includes a cavity for accommodating an oil-bearing raw material. The extruder is extended in the cavity. The ultrasonic wave generator is disposed on the frame and adjacent to the material tank. The heater is disposed on the frame and adjacent to the material tank. The heater is configured to produce heat to heat the cavity and the ultrasonic wave generator, and regulate the working frequency of the ultrasonic wave generator. When in use, the heater, the extruder, and the ultrasonic wave generator cooperate to separate oil from the oil-bearing raw material in the material tank.

The invention discloses a system for squeezing, smashing and winnowing municipal solid waste (MSW). The system comprises a primary squeezing and smashing, device and a secondary smashing and winnowing device. The system of the invention has good effect m squeezing, smashing and winnowing, can greatly reduce the water content of MSW and efficiently separate the MSW into combustible matters and non-combustible matters, so as to facilitate further subsequent utilization of the municipal waste; moreover, an upper jaw of a jaw crusher is connected with a spring device, so that the squeezing pressure, smashing effect and processing capacity of the jaw crusher can be adjusted according to the amount of the MSW. In addition, the system of the invention is further provided with emergency brake switches, spring protection devices and a sieve, so as to ensure the stability and the reliability of the system.

Various examples of a system for generating a densified product are provided. The system may include an extruder device and a liquid extraction section. The liquid extraction section may receive a material from the extruder device for densification and may then retain solids while permitting extraction of liquids as the material passes through the liquid extraction section under pressure. In various instances, a series of features forms at least a portion of the liquid extraction section and operates to retain the material on one side of the rods while permitting liquid to pass to another side of the features.
