[0046] In specific use, when it is necessary to screen and pack the roasted food, the operation is as follows:

[0047] First, pull the pull-out plate 10 to drive the pull-out plate 10 to block the rectangular blanking frame 15, and then pour the fried food into the outward expansion frame 12 and the fried food box 13, and at the same time control a plurality of heating rods 16 through the electric control heater to perform heating operation. The fried food is located in the fried food box 13, and when it is necessary to evenly heat and stir-fry it, it is also subjected to multi-stage screening operation, which is convenient for later packaging operation, and the driving motor 111 is started. Under the power output of the driving motor 111, the rotating rod 1112, the mounting sleeve and a plurality of flip plates 1111 on the mounting sleeve are driven to rotate synchronously.

Under the transmission of the synchronous belt 114, the second synchronous wheel 1142, the two rotating plates 115 and the rotating connecting rod 1161 are driven to rotate synchronously. At the same time, under the articulation operation, the two ends of each articulated connecting plate 1182 are driven to rotate along the corresponding The rotating plate 115 and the mounting pin are movably hinged, thereby driving each matching connecting plate 118 to be movably hinged along the corresponding two triangular connecting plates 1181 through the mounting pin. When several triangular connecting plates 1181 move synchronously, several fixed connecting plates 117 are driven to move synchronously, thereby driving the multi-stage screening components to move synchronously back and forth. In this way, it is convenient to grade and screen the roasted food through the multi-stage screening components, which is convenient for the multi-stage packaging operation in the later stage. At the same time, one machine can realize multi-functional operation, effectively reduce the cost investment, and increase the practicality of the overall device.

[0049] At the same time, through the coordination of the multi-stage screening components, when the multi-stage screening components move back and forth, see Figure 1 , Figure 3As shown, the fried food first falls into the first screening box 4, and the fried food that meets the secondary screening falls into the second screening box 6 through several first screening holes 17 on the first screening box 4, and the fried food that meets the secondary screening falls into the third screening box 9 through several second screening holes 18 on the second screening box 6, and then the fried food and debris that do not meet the requirements are collected through several third screening holes 19 on the third screening box 9. When classified collection is required, the fried food on the first screening box 4 is collected by the first lower hopper 5, the fried food on the second screening box 6 is collected by the second lower hopper 7, and the fried food on the third screening box 9 is collected by the third lower hopper 8, so as to realize the screening operation of fried food of different specifications, facilitate the screening and packaging thereof in the later stage, and increase the practicality of the overall device.
