The invention discloses a method and equipment for separating tenebrio molitor oil, protein and chitin. The invention discloses the method for separating the tenebrio molitor oil, the protein and the chitin. The method comprises the following steps of S1, screening and cleaning tenebrio molitor; S2, degreasing and drying; S3, crushing and filtering; and S4, cyclone separation. The invention further provides the equipment for separating the tenebrio molitor oil, the protein and the chitin, the equipment comprises a crushing bin, the top of the crushing bin communicates with a storage bin, a mounting bin is mounted at the top of one side of the crushing bin, and a motor is mounted on the side, close to the mounting bin, of one end of the crushing bin. Through rotary connection of a closed roller and a fixed shaft and cooperation of a supporting mechanism and a transmission mechanism, raw materials which do not reach the crushing standard on a first filter plate can be thrown to the position above a first crushing roller and a second crushing roller to be crushed again, and therefore transferring and re-crushing of the raw materials can be automatically completed; and furthermore, the crushing degree of the raw materials is fully ensured, the equipment is more convenient and higher in efficiency, and meanwhile, the filtering effect and the discharging smoothness can be ensured.
