After the material falls into the second extension tube 25, the material is located at one end of the second extension tube 25, which is close to the material inlet 212. When the roller set 2 rotates, the second extension cylinder 25 also rotates, and the third guide plate 252 stir-fries the materials so as to dry the materials; simultaneously, the material is conveyed to one end of the second extension tube 25 near the discharge hole 213 through the spiral groove formed between the third guide plates 252.
As shown in fig. 3 to 6, a baffle opening 262 is provided in the middle of the first baffle 26, and the baffle opening 262 communicates with the inside of the second extension cylinder 25 so that the material can fall from the baffle opening 262 into the next cylinder 21.
As shown in fig. 1-7, the first baffle 26, the second baffle 27 and the closing baffle 33 are provided with through holes, which are smaller, on the one hand, to avoid leakage of material from the through holes, and on the other hand, to facilitate air flow in the first extension tube 24 and the second extension tube 25, thereby facilitating evaporation of moisture.
As shown in fig. 3 to 7, an extension plate is fixed to one end edge of each of the first transfer port 241 and the second transfer port 251 near the axis of the drum 21 for preventing the material from leaking out of the first transfer port 241 and the second transfer port 251.
In this embodiment, for the material with less moisture, only a short period of drying is needed, the user only needs to move all the closing baffles 33 to overlap the extending baffles 261, so that the passage openings are exposed, then pass the bolts through the positioning holes 217 and the fixing holes 312 corresponding to the positions at this time, and screw the nuts, so that the positions of the closing baffles 33 can be fixed. After the material is put into the roller set 2, the driver 12 and the heating device are started, the heating device heats and dries the material, the driver 12 drives the roller set 2 to rotate, the first guide plate 211 can stir-fry the material on one hand, the material is prevented from being piled up, the drying speed of the material is improved, meanwhile, the material is pushed through the inclined first guide plate 211, the material can directly pass through each roller 21 in sequence, and the drying of the material is completed.
For materials with more water, because of the long time of drying, the user needs to remove the bolts and nuts on the fixing plate 216 and the limiting plate 311 on part of the rollers 21 according to the water in the materials, so that the transfer devices 3 in the rollers 21 can rotate relative to the rollers 21, at this time, the closing baffle 33 is adjusted to move to the corresponding passage opening positions, so that the closing baffle 33 blocks the passage opening, then the bolts pass through the positioning holes 217 and the fixing holes 312 corresponding to the positions at this time, and the nuts are screwed on, so that the positions of the closing baffle 33 can be fixed. The material is then put into a drum set 2 for drying.
After the material has been placed in the set of rollers 2, the drive 12 and the heating device are activated to dry the material and to move the material in the set of rollers 2 through the respective rollers 21.
When passing through the roller 21 where the closing baffle 33 overlaps the corresponding extension baffle 261, the material is moved from the inlet 212 to the outlet 213 by the first guide plate 211, and then pushed into the next roller 21 by the rotating plate 34.
When passing through the drum 21 with the corresponding passage opening blocked by the closing baffle 33, the first guide plate 211 moves the material from the feed opening 212 to the discharge opening 213, and then is blocked by the closing baffle 33 and the extension baffle 261, and is accumulated there. At this time, a groove capable of containing the material is formed between the rotating plate 34 and the extension baffle 261, and when the rotating plate 34 rotates past the lower side in the drum 21, the rotating plate 34 scoops out part of the material and leaves the material in the groove formed between the rotating plate 34 and the extension baffle 261. When the rotating plate 34 rotates from the lower side to the upper side in the drum 21, the material slides into the first transfer port 241 along the rotating plate 34 by the self gravity, and falls into the first extension tube 24.
After the material falls into the first extension tube 24, the material is stir-fried and dried through the second guide plate 242, and meanwhile, the material moves towards one end of the first extension tube 24 towards the feed inlet 212 until being blocked by the second baffle plate 27.
At this time, when the curved plate 271 rotates past the lower side in the first extension cylinder 24, the curved plate 271 scoops up a part of the material and leaves the material in the grooves formed between the curved plate 271, the receiving plate 272 and the second barrier 27. When the arc 271 rotates from the lower position to the upper position in the first extension tube 24, the material slides into the second transfer port 251 along the arc 271 by the self-gravity, and falls into the second extension tube 25.
After the material falls into the second extension tube 25, the third guide plate 252 stir-fry-dries the material, and simultaneously, the material moves toward one end of the second extension tube 25 toward the discharge port 213 until the material falls into the next drum 21 from the baffle port 262.
In summary, the material increases the distance that the material needs to move from the drum 21 to the next drum 21, thereby increasing the drying time of the material.
Therefore, the user can increase the distance the material needs to move by increasing the number of rollers 21 blocked by the closing baffle 33 and the extending baffle 261 to the discharge port 213, thereby increasing the time for drying the material. Thereby achieving the effect of controlling the drying time.
On the one hand, for the roller 21 with smaller quantity, the distance that the material needs to move can be prolonged through the first extension cylinder 24 and the second extension cylinder 25, so that the roller 21 with smaller quantity can also form a drying channel with longer length, thereby reducing the volume of the roller group 2 and facilitating transportation and storage.
On the other hand, the drying time of the materials is adjusted by increasing or reducing the distance that the materials need to be moved, so that the condition that the drying time is adjusted by adjusting the rotating speed of the roller set 2 is avoided, and the problems that the materials are not thoroughly stir-fried and are easy to stack and insufficient in drying due to the fact that the rotating speed of the roller set 2 is too slow are avoided.
