昇がせき止められ、循環が行われなくなり、以って乾燥
が良好に進まない危険性が大きかった。In the above-mentioned prior art, the drying apparatus having the vertical spiral rotary blade has some problems to be solved in the following points. That is, the material to be dried rises while being placed on the vertical spiral rotary blades that are connected from the top to the bottom while being pressed against the heat transfer surface. However, if the material to be dried is a highly viscous material to be dried, etc., once this material to be dried adheres to one vertical spiral rotary blade or a portion with a heat transfer surface, Since there is no transport path other than the vertical spiral rotary blade, there is a risk that congestion will occur at the above-mentioned adhering portion, and then there will be a dumpling-like expansion and the upper and lower blades will be blocked. Therefore, the rise of the material to be dried is stopped, the circulation is not performed, and there is a great risk that the drying does not proceed well.

った。Further, since the single vertical spiral rotary blade is connected from the top to the bottom and extends in a spiral shape, the clearance between the vertical spiral rotary blade and the heat transfer surface is from the top to the bottom. If the foreign matter present and mixed into the material to be dried is caught in the clearance, there is no escape area for the foreign matter, and the vertical spiral rotary blade may not rotate properly.

燥物が溜った状態が続き易く、乾燥効率を向上させるこ
とが難しかった。Further, in order to raise the material to be dried,
It is lifted by only one vertical spiral rotary blade. Therefore, the amount of the material to be dried is smaller than the total amount of the material to be dried located at the bottom of the drying tank, and it is difficult to bring the material to be dried into contact with the heat transfer surface at an early stage, and It was difficult to improve the drying efficiency because the dried material was likely to remain in the accumulated state.

った。Further, although the vertical spiral rotary blade has a space according to the pitch of the spiral between the upper and lower blades, when the material to be dried is pressed against the heat transfer surface by centrifugal force, Of the heat transfer surfaces between the upper and lower blades, unused heat transfer surface portions were likely to occur. Therefore, the entire area of the heat transfer surface is not used, that is, the area where the material to be dried does not contact is relatively large, and the entire surface of the heat transfer surface has not been effectively utilized.

た。Further, the material to be dried is successively spirally raised from the bottom to the top, and after reaching the uppermost portion, it is dropped and again raised. During this time, heat is applied to the material to be dried from the heat transfer surface to dry it. Therefore, in order to efficiently dry the material to be dried, the vertical spiral rotary blade has the best rotation speed adapted to various materials to be dried. Here, if the vertical spiral rotary blade is rotated at a speed higher than the rotation speed at which the drying efficiency of the material to be dried is higher than that at which the material is dried, the material to be dried does not satisfactorily rise along the spiral, resulting in poor drying efficiency. That is, in order to most efficiently dry the various objects to be dried, adjustment of the rotation speed of the vertical spiral rotary blade is indispensable, and conversely, this adjustment is troublesome.

However, it is difficult to use it when the object to be processed is brought into contact with the heat transfer surface to be heated and then dried.

Even if foreign matter mixed in the material to be dried gets caught in the clearance between the blade and the heat transfer surface, it is easy to escape and it is easier than the total amount of material to be dried located at the bottom of the drying tank. By increasing the amount of material to be dried, the drying efficiency is improved, and the entire heat transfer surface between the upper and lower blades is effectively used, and the rotating speed of the rotating blades does not have to be adjusted to be dried. It is to provide a technique for efficiently drying a product.

Each base blade 5a of the rotary winding blade 5 is continuously rotated in the direction of rotation R. At the same time, the boiler is driven to introduce the steam 7 into the jacket 6 and heat the heat transfer surface 2.

７，８参照）。By rotating the base blades 5a of the rotary winding blades 5 in the R direction, the objects to be dried 3 are separated by the base blades 5a.
The one end portion 18 is placed on the flat surface 8 of the base blade 5a and moves toward the other end portion 19 side along the base blade 5a. Since each base blade 5a has an elongated shape along the heat transfer surface 2 and the flat surface 8 extends obliquely upward from the one end portion 18 toward the other end portion 19, at this time, the object to be dried 3 is There is an action of being directed upward, and as a result, the material to be dried 3 is dried in the drying tank 4.
While being rolled up in the inner space A, it is pressed against the heat transfer surface 2 by the centrifugal force P while being rolled up (see FIGS. 7 and 8).

げ、カミ込みが継続しない。More specifically, the flat surface 8 of each base blade 5a that exerts a hoisting action on the material to be dried 3 and a pressing action on the heat transfer surface 2 by the centrifugal force P is applied to the heat transfer surface 2. Is elongated along the outer peripheral edge 10a of the flat surface 8 thereof.
Is formed in an arc shape along the heat transfer surface 2, so that the object to be dried 3 is not merely impacted, but the object to be dried 3
It effectively performs the winding action on the heat transfer surface and the pressing action on the heat transfer surface 2. The material to be dried is not moved upward in the drying device by one continuous blade, and the material to be dried 3 is individually wound up by the plurality of base blades 5a and moved to the heat transfer surface 2. It is pressed. For this reason, even the material 3 to be dried having a high viscosity does not adhere to the heat transfer surface 2, and the material to be dried does not stay at a specific position on the heat transfer surface 2. Further, each of the plurality of base blades 5a is independent because it has only a length within the circumferential range of 360 degrees when viewed from the plane and is independent from the outer peripheral end 10a of the flat surface 8 of each base blade 5a and the heat transfer surface 2. Since the clearance U between and is not connected to all the blades, even if foreign matter in the material to be dried 3 is caught in the clearance, it immediately escapes and does not continue to be caught.

Since the width is gradually widened in the direction opposite to the rotation direction R of the base blade 5a, it is effective in preventing foreign matter from getting caught. Therefore, the rotation resistance of the base blade 5a is increased by the foreign matter being caught. It is possible to avoid such a situation and continue smooth operation.

る。Further, since the plurality of base blades 5a can raise the material 3 to be dried located at the bottom of the drying tank 4 for each of the plurality of base blades 5a, the drying tank 4 can be lifted. The amount of the material to be dried 3 that rises is large compared to the total amount of the material to be dried 3 located at the inner bottom portion, and it is easy to bring the material to be dried 3 into contact with the heat transfer surface 2 at an early stage. Drying object 3 at the bottom of the drying tank 4
The scraping plate 20 is picked up by the scraping plate 20 and moves to the flat surface 8. However, when the protrusion 21 is provided at the outermost end of the scraping plate 20, the material to be dried 3 on the outer periphery of the bottom is moved toward the center. You can scoop up the scraping plate 20 while collecting.
Therefore, the dried object 3 to be scooped up by the scraping plate 20
It is possible to bring the material to be dried 3 into contact with the heat transfer surface 2 earlier by further increasing the amount of. In addition, since the material to be dried 3 on the outer periphery of the bottom portion in the drying tank 4 is sequentially moved toward the center by the protrusion 21, foreign matter is present in the clearance U between the outer peripheral end 10a of the base blade 5a and the heat transfer surface 2. Opportunity to get caught is reduced.
Thus, the protrusion 21 has a double action.

The article 3 to be rolled up later pushes up the article 3 to be dried upward, By continuously raising the material to be dried 3, the material to be dried 3 rises over the entire heat transfer surface 2,
The material 3 to be dried can be dried using the entire surface of the heat transfer surface 2. In addition, by rotating the base blade 5a, the material to be dried 3 is rolled up and pressed against the heat transfer surface 2 to be dried, whereby the rotation speed of the base blade 5a is increased to more strongly transfer the material to be dried 3. It can be pressed against the hot surface 2. As a result, the material to be dried 3 is further rolled up along the heat transfer surface, spreads in a thin film over the entire surface of the heat transfer surface 2, and heat is easily transferred to the material to be dried 3.

The other side has an evaporation surface F that comes into contact with the air in the space A in the drying tank 4 (FIG. 8). Then, the material 3 to be dried, which is in contact with the heat transfer surface 2, undergoes a certain amount of water evaporation on the spot due to the heat from the heat transfer surface 2. The material 3 to be dried, which has a low water content due to evaporation of water during contact with the heat transfer surface 2, moves to the evaporation surface F so as to replace the material 3 to be dried having a high water content. The material 3 to be dried that has moved to the evaporation surface F is exposed to the air in the space A, so that the water evaporation further proceeds.

Is intermittently pushed, and the material to be dried 3 rises along the heat transfer surface 2. That is, the material to be dried 3
Moves up from the heat transfer surface 2 to the evaporation surface F, and rolls up along the heat transfer surface 2 and rises.

When the base blades 5a rotate, the material to be dried 3 is rolled up by the respective base blades 5a, and as a result, the material to be dried 3 is rolled up. At this time, attention is paid to the movement of the material to be dried 3 near the two base blades 5a among the plurality of base blades 5a.

On the other hand, the material to be dried 3 located above the base blade 5a located on the downstream side is about to jump out obliquely upward from the base blade 5a located on the downstream side. That is, there is a portion where the flows of the two materials to be dried 3 overlap, and a turbulent flow occurs at the overlapping portion.

効果的に行うものである。As described in detail above, according to the present invention, the plurality of base blades respectively wind up the material to be dried, press it against the heat transfer surface, move it from the heat transfer surface to the evaporation surface, and along the heat transfer surface. Therefore, the water content of the material to be dried decreases as the material to be dried rises, and the dried material can be obtained in the upper part of the drying tank. Since the material to be dried is rolled up and pressed against the heat transfer surface to dry it, it does not easily adhere to the blades or heat transfer surface even if it is a highly viscous material to be dried. Since the temperature is raised over the entire heat transfer surface, the material to be dried does not stagnate. Moreover, the flat surface of each base blade that exerts a hoisting action on the material to be dried and a pressing action on the heat transfer surface by a centrifugal force is an elongated shape along the heat transfer surface and extends from one end to the other end. Since it extends diagonally upward, it does not just give a shock to the dried object,
It effectively performs the hoisting action on the material to be dried and the pressing action on the heat transfer surface.

である。Further, since each of the plurality of base blades is independent and has only a length within the circumferential range of 360 degrees when viewed from the plane, the outer peripheral edge of the flat surface of each base blade and the heat transfer surface are independent. Since the clearance between the blades is not continuous over the entire blade, foreign matter in the material to be dried does not get caught in the clearance.
In particular, if the clearance is gradually widened in the direction opposite to the rotation direction of the base blade, it is effective to prevent the foreign matter from getting caught.

を向上させ易い。Further, by the plurality of base blades, the material to be dried located at the bottom of the drying tank can be raised by the plurality of base blades, and the total amount of the material to be dried located at the bottom of the drying tank can be increased. As compared with the above, the amount of the material to be dried increases, and it is easy to bring the material to be dried into contact with the heat transfer surface at an early stage, and thus it is easy to improve the drying efficiency.

It is effective for scooping up the material to be dried and can further increase the amount of the material to be dried, and the material to be dried located on the outer periphery of the bottom of the drying tank has a rotating shaft. Since it is moved toward the center, it can also contribute to the prevention of the above-mentioned clogging.

By doing so, the material to be dried rises over the entire heat transfer surface, and the material to be dried can be dried using the entire surface of the heat transfer surface. Can be used for.

伝わり易く、乾燥効率も向上する。In addition, by rotating a plurality of base blades, the material to be dried is pressed against the heat transfer surface to be dried while rolling up the material to be dried, so that the material to be dried is more strongly transferred by increasing the rotation speed of the base blade. Can be pressed against hot surfaces. As a result, the material to be dried further rises along the heat transfer surface, spreads in a thin film over the entire surface of the heat transfer surface, heat is easily transferred to the material to be dried, and drying efficiency is also improved.
