As shown in fig. 1 and 2, the adjustable column set 33 includes a plurality of adjusting columns 331 corresponding to the positions of the pulling columns 3223 and penetrating through the counterweight chamber 313 to the inner side of the induced draft housing 311, a fixing column 332 for clamping the pulling columns 3223 is installed at one end of each adjusting column 331, a sliding sleeve 333 connected with the inner wall of the counterweight chamber 313 is sleeved on the side wall of the other end of each adjusting column 331, a pulling return spring 334 connected with the adjusting column 331 is installed in the sliding sleeve 333, a drawing air bag 335 is installed at the position, corresponding to the sliding sleeve 333, on the outer side wall of the counterweight chamber 313, and a movable air guiding sheet 336 is installed on the adjusting column 331.

In this embodiment, as the lengths of the pulling pillars 3223 are set in a linear decreasing trend, as shown in fig. 1, when the inserting frame 321 is inserted, the shortest pulling pillar 3223 will gradually block the fixing pillar 332 on the longest adjusting pillar 331 to achieve the purpose of connection, the pulling pillar 3223 may be in an L-shaped structure, and a U-shaped groove may be formed on the fixing pillar 332.

In order to achieve the purposes of driving the fixed carrying net 322 to move so as to guide the hot air to move and adjusting the area and time of hot air impact on the surface of the dried tofu, when the dried tofu is put into practice, if the fixed carrying net 322 needs to be driven to shift, the drawing air bag 335 is directly pressed, then the drawing air bag 335 draws out air in the sliding sleeve 333 so as to reduce the pressure, that is, the adjusting column 331 descends and squeezes the return spring 334 to facilitate the subsequent resetting operation, then the descending adjusting column 331 takes the corresponding carrying net block 3221 to descend, and other adjusting columns 331 also operate according to the above operations, then the plurality of carrying net blocks 3221 gradually incline until the state of fig. 2 is presented, and when the drying operation is performed, the area and time of hot air impact can be adjusted through the movable air guide sheets 336.

As shown in fig. 2 and 1, the movable air guiding plate 336 includes a plurality of inclined air guiding plates 3361 having a V-shaped longitudinal section and fitted around the side wall of the adjusting column 331, an adjusting bag 3362 sealingly connected to the inclined air guiding plates 3361 is installed on the side wall of the adjusting column 331, a pair of push plates 3363 symmetrical with respect to the adjusting column 331 is provided through the side wall of the inclined air guiding plates 3361, an air guiding rubber sheet 3364 connected to the inner side wall of the inclined air guiding plates 3361 is installed on one side of the push plates 3363, a threaded post 3365 penetrating the weight chamber 313 to the outside is connected to the other side of the push plates 3363, and a connecting rubber sheet 3366 having an inverted V-shaped longitudinal section is installed between adjacent inclined air guiding plates 3361.

In order to adjust the area and time of hot air impacting on the other side of the dried tofu, in the implementation, the threaded post 3365 is directly rotated to ascend or descend, here, taking fig. 2 as an example, the threaded post 3365 descends, then the descending threaded post 3365 pulls the push sheet 3363 to descend, when the push sheet 3363 descends, the push sheet 3363 slides along the surface of the oblique air guide 3361 and stretches and opens the V-shaped opening of the oblique air guide 3361, in the process, the adjusting pocket 3362 assists the oblique air guide 3361 to expand, the connecting rubber sheet 3366 is gradually deformed to adapt to the pressing force from different directions, and the inclination direction of the wind guide rubber sheet 3364 is changed, namely, the direction of the hot air impacting on the dried tofu along the surface of the wind guide rubber sheet 3364 is changed, and if the hot air impacting time needs to be adjusted, the threaded post 3365 is rotated up and down continuously.

As shown in fig. 3, the alternate driving mechanism 2 includes a rotating frame 201 rotatably connected to the inner wall of the airtight dryer 1, the inner side wall of the rotating frame 201 is connected to the off-axis column 312, and the inner side wall of the rotating frame 201 is provided with a stabilizing column 202;

the airtight dryer 1 comprises a sealing cover 101 sleeved on the outer side of a rotating frame 201, an annular air guide sleeve 102 is installed on the inner side wall of the sealing cover 101, an air induction tube 103 with a V-shaped longitudinal section and used for guiding hot air to enter an air induction cover body 311 is installed on the inner wall of the top of the annular air guide sleeve 102, and an air gathering block 104 with a V-shaped longitudinal section is installed on the inner side wall of the air induction tube 103.

This airtight drying apparatus 1 is when carrying out the stoving operation, induced air cylinder 103 can be direct to coincide with the opening of induced air cover body 311, so that hot-blast ability fully gets into induced air cover body 311, simultaneously hot-blast wind piece 104 that gathers when getting into can play the effect of assembling, make hot-blast direct assemble under impact in one, its velocity of flow direction can light regulation promptly, after later hot-blast stoving completion, remaining hot-blast can assemble in annular air guide sleeve 102 in order to carry out the auxiliary heating, make other dried tofu of not accomplishing the stoving can preheat the operation, and drive mechanism 2 in turn is at the during operation, it drives all induced air cover body 311 movements through rotating turret 201, and stabilizing column 202 can play stable effect, make induced air cover body 311 can not rock about when receiving the wind blow.

Example 2:

the invention also provides a drying method of the intelligent alternate type dried tofu sterilizing and drying device, which comprises the following steps:

s100, carrying the dried tofu through the carrying net block, and inserting the inserting frame into the air inducing cover body to complete loading of the dried tofu;

s200, driving a plurality of induced draft hood bodies loaded with dried tofu to alternately contact the induced draft barrels through an alternate driving mechanism, gathering hot air through an air gathering block and sending the hot air into the induced draft hood bodies, and driving an adjusting column group to move so as to drive a bearing net block to incline;

s300, guiding hot air to pass through the surface of one side of the dried tofu and then contact with the movable air guide sheet through the inclined bearing net block, and impacting the surface of one side of the dried tofu in forest through the movable air guide sheet to complete the operation of double-sided synchronous drying.

The above embodiments are only exemplary embodiments of the present application, and are not intended to limit the present application, and the protection scope of the present application is defined by the claims. Various modifications and equivalents may be made by those skilled in the art within the spirit and scope of the present application and such modifications and equivalents should also be considered to be within the scope of the present application.
