The specific operation flow is as follows:

the seventh sliding block 137 is shifted towards the direction that the first rotating block is opened, at this time, the frame 134, which is originally extruded by the seventh sliding block, loses the extrusion of the seventh sliding block, so as to eject outwards under the action of the sixth elastic element 136, at this time, the inclined block located behind the rack is extruded by the extrusion inclined plane in the frame, so as to pull the rack 104 to move downwards, the downward movement of the rack drives the fifth sliding block 1012 to eject outwards, at this time, the fifth sliding block plays a fixing role, and at the same time, the clamping groove 138 on the seventh sliding block extrudes the clamping surface 139 on the fixing rod, so as to extrude the fixing rod 611 to reset, the reset fixing rod drives the blanking turning plate 612 to reset and close, while the seventh sliding block 137 moves, the eighth sliding block is pushed to move towards the tenth cavity 1310, so as to pull the rope 1312, so as to pull the third sliding block 115 apart, so as to separate the first one-way tooth 117 from the second one-, at the moment, the rotation of the blanking turning plate is not limited any more, the working sequence is that the third slide block is pulled firstly, then the fixed rod is driven to reset through the matching between the clamping groove and the clamping surface, at the moment, the rotating rod can be screwed out of the fixed rod, the sealing plate is enabled to turn downwards around the first rotating piece 64 through extruding the sealing plate 65, so that an opening is opened to put materials into the opening, the materials fall on the blanking turning plate for temporary storage, after blanking is completed, the twisting wheel 79 is screwed to rotate, so that the second transmission gear 78 is driven to rotate through the transmission of the transmission block 77, the second transmission gear is matched with the first transmission gear, so that the rotation of the second transmission gear drives the first transmission gear to rotate, the first transmission gear rotates above the feeding barrel, then the third soft film 72 is twisted in a twist form, and a central hole formed by the third soft film in the twisting process of the third soft film becomes smaller gradually, the limit is reached after the reversing to a certain degree, the function of sealing the opening is realized at the moment, the effect of sealing the auxiliary sealing plate is realized, then the seventh sliding block is reversely pushed, the seventh sliding block loses the limitation on the third sliding block and the fixed rod, the frame body is extruded, the fixing of the inclined block is unlocked by the movement of the extruded frame body, so that the fixing of the rack is unlocked, the rack can move freely under the influence of air pressure at two sides,

after the steps are completed, air can be pumped out, the air in the air pumping cavity 62 is pumped out, when the air in the air pumping cavity is pumped out continuously, the air pressure in the air pumping cavity 62 is gradually reduced to form a certain pressure difference with the air pressure in the first air cavity 53, so that the second sliding block 83 obtains upward jacking force through the air collecting groove 84, because the blanking turning plate cannot turn over under the fixation of the fixing structure, a certain degree of force accumulation is carried out, when the first air cavity 81 is filled with air, the third cavity 113 which is connected with the first air cavity through the air collecting groove is also in a closed normal pressure state, at the moment, because the air quantity in the air pumping cavity is gradually reduced, the volume of the air in the first air cavity expands to push the third sliding block to move outwards, so that the convex block and the first one-way tooth on the convex block are pushed to move outwards, the first one-way tooth is clamped on the second one-way tooth on the second block body below, the two are engaged, so that the turning plate can only move in one direction at the moment.

Along with the continuous reduction of the internal air, when the air pressure of the upper air suction cavity is continuously close to the air pressure of the lower upper barrel, the rack continuously moves upwards, the upward movement of the rack enables the fifth sliding block 106 to retract inwards, so that the fixation of the blanking turning plate is lost, the blanking turning plate is overturned afterwards, the material falls from a gap between the blanking turning plates and falls onto the material guide plate, then the dried material enters the lower barrel from the material outlet and is stored, the water is continuously evaporated by the heating of the heating block 48 and is accumulated along the outer wall of the air guide block 43 to the position far away from the center of the top end of the barrel, then the temperature below the condensing tank is far lower than the temperature of the heating part below due to the normal temperature water added in the condensing tank 45, so that the water vapor is condensed at the position and then falls into the upper part of the lower collecting block and is accumulated on the collecting block, and then, after a certain degree is reached, the water in the barrel is pumped out by the water pump 3, the filled lower barrel can be taken down by screwing, at the moment, the air pressure above the lower barrel is normal pressure, so that the feed port is closed, the sealing is completed, the barrel can be sealed for a long time, and the steps are repeated.
