[0019] As Figures 1-2 ​The utility model provides a kind of edible oil expression refining device, including hydraulic column 1 and expression cavity 2, hydraulic column 1 is connected with hydraulic press, hydraulic press is used to control the up-down reciprocating movement of hydraulic column 1 in expression cavity 2, cavity 3 is set in the middle of hydraulic column 1, connecting column 301 is provided in cavity 3, spring 302 is fixedly connected at the top of connecting column 301, spring 302 top is fixedly connected with cavity 3, filter plate 303 is fixedly connected at the bottom of connecting column 301, hydraulic column 1 bottom is also fixedly connected with oil pressing plate 304, opening is set on oil pressing plate 304 for connecting column 301 to penetrate, clamping block 306 is elastically connected on the both sides of filter plate 303, clamping groove 305 is symmetrically set in the inner wall of expression cavity 2.

[0020] Specific: the raw material for oil pressing is put into expression cavity 2, hydraulic machine controls hydraulic column 1 to move down, oil pressing plate 304 and filter plate 303 move down synchronously, until filter plate 303 is in contact with the bottom position of expression cavity 2, filter plate 303 is in contact and cannot move, and clamping block 306 is connected with clamping groove 305, then hydraulic column 1 continues to move down, and hydraulic column 1 drives oil pressing plate 304 to perform a pressing operation on the raw material;

[0021] After one-time oil pressing, hydraulic column 1 moves up to reset, filter plate 303 remains stationary through the clamping effect of clamping block 306 and clamping groove 305, until the spring 302 reaches maximum elastic potential, then the clamping block 306 elastically separates from the clamping groove 305, and then the filter plate 303 drives the raw material to move up and vibrate elastically, thereby loosening the raw material pressed once, facilitating the downward flow of oil, and finally repeating the oil pressing operation.

[0022] After one-time oil pressing, the highest position of oil pressing plate 304 is flush with the outlet of expression cavity 2, to prevent the raw material from splashing out of expression cavity 2 due to vibration.

[0023] It can be understood that: through the elastic vibration of filter plate 303, the raw material is loosened and the oil is extracted, improving the efficiency and oil yield of oil pressing.
