The lower opener and closer 214 avoids the lower push block 211, and the reset 115 makes the discharge cover 212 seal the discharge slot.

[0031] Working principle: After the material enters the separation device 107, the motor drive device 110 drives the separation blade 108 to rotate, enabling the material to enter the interior of the heat cylinder 201 through the feed channel 208 and the material channel. The main motor 106 of the motor drives the frying blade 206 and the main gear 207 to rotate. The main gear 207 meshes with the auxiliary gear 203 to rotate, and the auxiliary gear 203 meshes with the secondary gear 202 to rotate. The upper push block 215 on the secondary gear 202 drives the upper opener 209, and the feed cover plate 204 and the upper opener 209 move along with the secondary gear 202. After the material enters the interior of the heat cylinder 201, the upper opener 209 comes into extrusion contact with the upper extrusion block 205, causing the upper opener 209 to avoid the upper push block 215 and be pulled back to its initial position by the auxiliary spring 117 to seal the feed opening. The main motor 106 of the motor drives the frying blade 206 to stir and fry the material. The fan motor 111 drives the exhaust fan blade 112 to rotate to extract the high-temperature gas inside the heat cylinder 201, preventing the material from being damaged due to excessive temperature and making it reach the expected standard. After a period of time, the lower push block 211 on the secondary gear 202 will drive the lower opener 214, causing the discharge cover plate 212 to move along with the secondary gear 202. Then, the lower opener 214 comes into extrusion contact with the lower extrusion block 213, causing the lower opener 214 to avoid the lower push block 211 and be pulled back to its initial position by the reset 115 to reseal the discharge slot. As the discharge cover plate 212 opens the discharge slot, the material falls out of the heat cylinder 201 from the outlet slot and lands on the conveyor belt 103. As the secondary motor 104 drives the conveyor belt 103, the material will be transferred into the collection box 101 (material storage box) along the conveyor belt 103.

[0032] The above is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
