In the actual operation process: firstly, the movable drying rack is positioned outside a drying chamber, and the strip-shaped baffle is supported on the corresponding drying sieve; then, the fresh mushrooms are uniformly placed on the drying sieve, the strip-shaped baffle plates are not provided with the fresh mushrooms, and after the fresh mushrooms are placed on the drying sieve on the movable drying rack, the fresh mushrooms are moved into the drying chamber through the inlet and the outlet and are supported on the floating support bottom plate; after the movable drying rack with the fresh mushrooms placed is supported on the floating support bottom plate, because the fresh mushrooms are heavy, the weight of the movable drying rack acting on the floating support bottom plate is larger than a set value, the movable drying rack and the floating support bottom plate move downwards until the floating support bottom plate is supported on the lower limiting part, so that the strip-shaped baffles in the same vacancy air guide structure are supported on the two corresponding strip-shaped support flat plates, and the strip-shaped baffles are separated from the corresponding drying screens; therefore, the strip-shaped baffle plate of each vacant position air guide structure is separated from the corresponding drying screen, so that a blank part without fresh mushrooms is formed on each drying screen, and the blank part can be used for hot air circulation; meanwhile, after the movable drying rack is moved into the drying chamber, a gap is inevitably formed between the movable drying rack and the inner wall of the drying chamber, and the gap can also be used for hot air flow circulation; therefore, in the initial stage of drying the mushrooms: hot air flow entering the bottom of the drying chamber from the air inlet can flow from bottom to top through a gap between the movable drying rack and the inner wall of the drying chamber so as to ensure that the fresh mushrooms at the peripheral part of the drying sieve can quickly remove moisture on the surfaces of the mushrooms; the mushroom drying sieve can also ensure that the surface moisture of the fresh mushrooms in the middle of the drying sieve can be quickly removed through the circulation of blank parts formed on the drying sieves from bottom to top, so that the problems that the surface moisture of the mushrooms cannot be quickly removed by the mushrooms in the middle of the drying sieve due to the fact that hot air flow is still difficult to circulate in the space in the middle of the drying sieve at the initial stage of mushroom drying, the drying efficiency of the mushrooms in the middle of the drying sieve is reduced, and the drying quality of the mushrooms in the middle of the drying sieve is influenced can be effectively solved;
after the mushrooms are dried for a period of time, the moisture of the mushrooms is reduced, the weight of the mushrooms is reduced, and a certain amount of inward rolling shrinkage is generated at the edges of the mushrooms, so that gaps are formed among the mushrooms on the drying sieve; in the process that the weight of the mushrooms is gradually reduced, when the weight of the movable drying rack acting on the floating support bottom plate is smaller than a set value, the movable drying rack and the floating support bottom plate move upwards at the pre-tightening compression spring until the floating support bottom plate abuts against the upper limiting part, and each strip-shaped baffle plate is supported on the corresponding drying sieve, so that a blank part on each drying sieve, which is not provided with the fresh mushrooms, is shielded again, at the moment, as the mushroom cover edge on the drying sieve is rolled inwards by a certain amount, gaps are formed among the mushrooms on the drying sieve, partial sieve pores of the drying sieve are opened, hot air can directly circulate from bottom to top through the sieve pores of the drying sieve, the drying efficiency and the quality of the mushroom drying subsequent stage cannot be influenced, and the mushroom drying efficiency and the quality of the mushroom drying subsequent stage are ensured.
Further, as shown in fig. 5, a strip-shaped baffle is provided near the middle of the drying screen. The strip-shaped baffles in any two drying sieves which are adjacently distributed are staggered.
Further, as shown in fig. 4 and 5, the vacancy air guide structure further comprises two vertical limiting plates 3.3 arranged on the upper surface of the drying screen. The two vertical limiting plates are parallel. The positioning holes are located between the two corresponding vertical limiting plates, and the strip-shaped baffle is located between the two corresponding vertical limiting plates. So, can avoid the mushroom to enter into between two vertical limiting plates for in mushroom stoving process, the bar baffle can support once more on the stoving sieve that corresponds, shelters from once more with the blank position that does not place bright mushroom on each stoving sieve.
Further, as shown in fig. 1 and 2, the strip-shaped support plates are horizontally distributed, one end of each strip-shaped support plate is close to the inlet and the outlet, and the other end of each strip-shaped support plate extends into the drying chamber. Two strip-shaped supporting flat plates of the same supporting component are positioned at the same height.
Further, as shown in fig. 1 and 2, the floating support structure further includes a vertical support sleeve disposed on the bottom surface of the drying chamber and a vertical guide rod 2.5 slidably disposed in the vertical support sleeve, and a lower end of the vertical guide rod is connected to a lower surface of the floating support bottom plate. The pre-tightening compression spring is sleeved outside the vertical support sleeve. The vertical supporting sleeve forms the lower limiting piece. The upper limiting piece is fixed on the side wall of the bottom of the drying chamber.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and all simple modifications, alterations and equivalents of the above embodiments according to the technical spirit of the present invention are still within the protection scope of the technical solution of the present invention.
