Both ends of the moving column 49 are slidably set in the transverse groove 43, and the top of the moving frame 48 is fixedly installed on the drying screen 25.

When the fried food to be dried and de-oiled enters the position above the drying screen 25, the drying motor 15 is started to rotate the adjusting screw 28, so that the adjusting disk 27 drives the multiple adjusting frames 30 to move downward along the adjusting groove 38. Then, with the cooperation of the above-mentioned hinge part and the moving part, the multiple drying screens 25 are rotated to a certain angle along the edge of the drying plate 24, so that the fried food can be effectively discharged.

Example 2

In order to further ensure the effective separation of the residue and the fried food, and to also utilize the heat for secondary drying and de-oiling, the present invention also provides another embodiment. The difference between this embodiment and the above embodiment is that a drying ring 33 is installed on the inner wall of the drying tank 1 located on the lower side of the de-oiling plate 22, and the drying tank 1 is also provided with a blowing mechanism for introducing heat into the drying ring 33.

The blowing mechanism includes a blower 4 installed on the outer wall of the drying tank 1, the blower 4 is connected to the drying ring 33, and a plurality of inclined blowing pipes 34 are installed on the inner wall of the drying ring 33.

The other end of the drying pipe 35 is connected to an exhaust pipe 8 arranged on the outer wall of the drying tank 1, and an exhaust pump 7 is installed on the exhaust pipe 8. A plurality of recovery blades 19 are also installed on the stirring shaft 13 located on the inner side of the recovery hood 16, thereby accelerating the introduction of heat carried in the oil vapor into the interior of the recovery hood 16.

When the fried food after drying and deoiling is located on the drying screen 25, the blower 4 and the exhaust pump 7 are started. The exhaust pump 7 sucks the oil vapor originally generated by high-temperature evaporation in the deoiling area into the drying tube 35. At the same time, the blower 4 blows air into the drying ring 33, so that the heat carried by the drying tube 35 is blown to the fried food on the drying screen 25 through the blowing pipe 34. On the one hand, the fried food is dried and deoiled for the second time. On the other hand, it also accelerates the separation and falling off of the residue on the fried food, further improving the drying quality.

In summary, the fried food is first introduced into the drying tank 1 through the feeding hopper 9, and then the excess oil contained in the fried food is fully discharged on the de-oiling plate 22 in the de-oiling area of the drying tank 1 with the cooperation of the heating de-oiling mechanism, and then the residue attached to the de-oiled fried food is dried and separated on the drying screen 25 in the drying tank 1 with the cooperation of the air-blowing de-slag mechanism, and the residue and secondary oil are discharged through the drying hole 37, and finally the drying motor 15 is started, and then the de-oiled and de-slaged fried food is discharged with the cooperation of the adjustment component. The whole operation process is quick and convenient, and it is worth promoting and using.
