[0053] In summary,

[0054] When the walnut raw materials are subjected to flash drying, the walnut raw materials are first added to the inside of the upper hopper 2, at which time the walnut raw materials are stratified under the action of the two sets of partitions 407 in the upper hopper 2, then the hot air fan 106, the flash dryer main body 1 and the stirrer 108 arranged in the flash dryer main body 1 are started, then the driving motor 203 is started to rotate the spiral conveying shaft 202, and then the raw materials in the inside of the upper hopper 2 are discharged to the inside of the fixed cylinder 201, and the raw materials are fed to the inside of the flash dryer main body 1 through the spiral conveying shaft 202.

[0055] Further, when the spiral conveying shaft 202 rotates, at which time the first hollow cylinder 401, the second hollow cylinder 402 and the two sets of perforated plates 405 arranged on the outer walls of the hollow cylinders in the inside of the upper hopper 2 rotate equally under the connecting action of the first belt 403 and the second belt 404, at which time the raw materials in the inside of the upper hopper 2 can be preliminarily scattered and mixed under the stirring action of the perforated plates 405.

[0056] And in the process of rotation of the perforated plates 405, the two sets of perforated plates 405 away from the ends of the two sets of hollow cylinders respectively abut against the bottom end faces of the two sets of partitions 407 arranged in the inside of the upper hopper 2, when the perforated plates 405 rotate away to the position not in contact with the partitions 407, the pushing force acting on the partitions 407 disappears, so that the partitions 407 can rotate downward with the support frames 406 as the center under the action of gravity, so that intermittent upward and downward vibration of the partitions 407 is realized, so that intermittent downward discharge of the raw materials on the top end faces of the partitions 407 is realized, so as to avoid the raw materials from being accumulated together, resulting in small gaps for gas flow between the raw materials.

[0057] And at the same time, when the second hollow cylinder 402 rotates, the half gear 602 arranged on the end of the outer wall of the fixed box 601 extending into the inside of the second hollow cylinder 402 rotates equally, when the part of the half gear 602 provided with the clamping teeth contacts the rack 604, at which time the rack 604 and the moving plate 603 arranged on the top end of the rack 604 slide upward along the guide rail 701 under the meshing action therebetween, the knocking rod 605 fixedly connected to one side of the moving plate 603 moves equally, and the moving plate 603 can compress the telescopic rod 606 and the spring 607 in the process of upward movement.

[0058] When the half gear 602 is not in contact with the rack 604, the meshing effect disappears, and the external pressure on the telescopic rod 606 and the spring 607 disappears, so that the elastic force of the spring 607 continuously increases, and the rack 604, the moving plate 603 and the knocking rod 605 move to the position close to the second hollow cylinder 402 under the elastic force of the spring 607, so that the bottom end of the knocking rod 605 collides with the outside of the second hollow cylinder 402. At this time, the second hollow cylinder 402 vibrates under the external impact, and the hole plate 405 connected with the second hollow cylinder 402 vibrates, so that the hole plate 405 is not blocked by the raw materials. The hole plate 405 arranged on the outer wall of the first hollow cylinder 401 and the hole plate 405 arranged on the outer wall of the second hollow cylinder 402 have the same effect.

[0059] In particular, when the air heater 106 is started, part of the dry hot air flows into the inside of the connecting pipe 504 through the gas conveying pipe 505 arranged at one end of the connecting channel 107, and then the hot air enters the inside of the hollow block 502 through the fixed hole 503 arranged on the outer wall of the hollow block 502 and the connecting pipe 504, and then the hot air enters the inside of the two groups of hollow cylinders through the connecting port 501 connected with the hollow block 502, and then the hot air flows into the inside of the feeding hopper 2 through the holes arranged on the outer wall of the hole plate 405 connected with the two groups of hollow cylinders, and the hot air contacts with the raw materials in the feeding hopper 2, so that the hot air preliminarily dries the raw materials.

[0060] Further, after the preliminarily dried raw materials contact with the screw conveying shaft 202, the raw materials enter the inside of the flash dryer main body 1 through the screw conveying shaft 202, at this time, the stirrer 108 continues to stir and scatter the raw materials, and at the same time, the hot air enters the inside of the flash dryer main body 1 through the connecting channel 107, so that the raw materials are subjected to strong shearing, blowing and rotating effects, so that the raw materials with low moisture content and small particle size are carried upward by the rotating air flow, and the raw materials are further dried in the upward process, and the raw materials with high moisture content and large particle size continue to be located at the bottom of the flash dryer main body 1, so that the stirrer 108 and the hot air continue to stir and dry the raw materials.

[0061] Finally, the flash-dried raw materials enter the inside of the cyclone separator 101 through a group of conveying pipes 109, so that the cyclone separator 101 screens the flash-dried raw materials, and the raw materials meeting the requirements are screened into the inside of the collector 102 through a group of conveying pipes 109, and the waste gas generated in the flash drying process enters the inside of the bag filter 103 through a group of conveying pipes 109, and the waste gas is discharged to the outside environment through the exhaust pipe 105 arranged at the induced draft fan 104 after being filtered by the bag filter 103. In the later stage, the flash-dried raw materials can be collected through the discharge pipe at the bottom of the collector 102.

[0062] The foregoing is considered as illustrative only of the principles of the application and the forms thereof which are demonstrated by the described embodiments. Further, those skilled in the art will readily recognize that certain of the above described embodiments can include, inter alia, alternate configurations and steps thereof known in the art. Therefore, there is no intention that this application be limited as described unless by the recitations of the claims that follow, or by appropriate words taken in the broader and / or more general sense.
