Further, the first conveyor belt 32 has a bearing portion 321 and an oil filtering portion 323, the bearing portion 321 forms the material bearing position 31, the extruding mechanism 50 and the oil filtering portion 323 are disposed at an interval to form an extruding space, so that the fried food embryo body can be placed on the bearing portion 321, and then the fried food embryo body is driven to the lower portion of the extruding mechanism 50 by the rotation of the first conveyor belt 32, that is, the extruding space is extruded. Furthermore, the bearing portion 321 and the oil filtering portion 323 are both provided with a plurality of oil filtering holes 33 to allow oil to drip.

It should be understood that the carrier 321 referred to in this application is a portion of the first conveyor belt 32 which is offset from the pressing mechanism 50 and is used for carrying the fried food embryo, and the oil filter 323 referred to in this application is a portion of the first conveyor belt 32 which faces the pressing mechanism 50, and the carrier 321 and the oil filter 323 change in real time instead of a fixed portion of the first conveyor belt 32 as the first conveyor belt 32 is driven.

The pressing mechanism 50 further includes a pressing roller assembly 56, the pressing roller assembly 56 is assembled between the pressing portion 521 and the transmission portion 523, and abuts against the pressing portion 521, so that the pressing portion 521 is pressed by the pressing roller assembly 56, so as to further press the fried food embryo, and improve the oil filtering effect.

In some embodiments, the distance between the extrusion roller assembly 56 and the oil filtering portion 323 is adjustable, and the distance between the extrusion roller assembly 56 and the oil filtering portion 323 can be adjusted according to requirements, so as to adjust the height of the extrusion space, so as to be suitable for processing fried food embryo bodies with different thicknesses, or the height of the extrusion roller assembly 56 is adaptively adjusted according to the oil content of the fried food embryo bodies, so as to adjust the extrusion force applied to the fried food embryo bodies, and optimize the oil filtering effect on the premise of ensuring that the shape of the fried food embryo bodies is not damaged.
