きなトルクが必要となるという問題点があった。By the way, in this conventional screw type heating / cooling device, two screw blades are completely meshed with each other over substantially the entire length of the screw shaft, and the raw material is fed at the groove portion (valley portion) of the screw blade. Therefore, the transfer of the raw material was too fast, and it was difficult to secure the residence time required for heating and cooling. In addition, since the raw material fixed to the inner wall surface of the casing and the screw blades come into contact with the entire outer peripheral surface, the entire outer peripheral surface of the screw blades wears, the repair area at the time of wear increases, and the repair cost increases. Is not easy, and moreover, to prevent wear, the entire outer peripheral surface of the screw blade is sprayed with ceramics,
It was necessary to protect it with hardfacing. Furthermore, the area of the minimum gap between the outer peripheral surface of the screw blade and the inner wall surface of the casing becomes too large, and the raw material may not be scraped off and may be pressed against the inner wall surface to become stuck, and the frictional force also increases and the screw shaft There has been a problem that a large torque is required to drive and rotate the.

An object of the present invention is to provide a screw type heating / cooling device which is easy and requires a small driving torque.

When it becomes, it flows into the lower part of the screw blade from the notch. As a result, the temporary transfer of the raw material is stopped. Then, the raw material that has stopped being transported is not transported, the clew blade makes one rotation, and is extruded by the raw material transported from the rear by the portion without the notch, and the extruded raw material is further transported forward. It Further, the raw material pressed against the inner wall surface of the casing is scraped off by the projections, and the friction of the raw material with respect to the outer peripheral surface of the screw blade is significantly reduced as compared with the scraping on the entire outer peripheral surface having no projections.

る。In the hollow screw shafts 3 and 4, FIG.
A heating medium such as steam or warm water or a cooling medium is supplied as shown in FIG. 2, but a part of this supply medium passes from one end (the right end in the figure) of the hollow screw shafts 3 and 4 through a communication hole (not shown). It flows into the hollow screw blades 5 and 6 and further from the inside of the hollow screw blades 5 and 6 to another end portion of the hollow screw shafts 3 and 4 through another communication hole (not shown). A heating medium or a cooling medium is likewise supplied to the jacket 2. In FIG. 2, 13 is the inflow port, and 14 is the outflow port. A steam chamber 15 is formed inside the casing 1 above the hollow screw blades 5 and 6. In FIG. 1, 16 is a raw material supply port provided on the top wall of the casing 1, 17 is the same discharge port, 18 is a ventilation port, and 19 is an exhaust port.

る。The raw material supplied from the raw material supply port 16 is sent by the hollow screw blades 5 and 6 from the upstream part to the downstream part (in this example, from the left direction to the right direction) in the phase traveling direction, during which the raw material is supplied to the jacket 2. And is heated by, for example, a heating medium flowing in the hollow screw shafts 3, 4 and the hollow screw blades 5, 6. The vaporized gas vaporized by this heating is made into high humidity air by the ventilation air sent from the ventilation port 18 in the vapor chamber 15, and is exhausted from the exhaust port 19.

分にとれ、原料20が全く滞留することなく速く移送され
てしまうという現象を防止できる。When the raw material 20 rises above the hollow screw blades 5 and 6 during the transfer of the raw material, as shown in FIG. 4, the cutout portion 7 of one screw blade 5 becomes a valley portion of the other screw blade 6. When they face each other, they flow into the lower portions of the screw blades 5 and 6 from the cutout portions. As a result, the temporary transfer of the raw material 20 is stopped (Fig. 4 (A),
(B)). Then, the raw material 20 whose transfer is stopped is not transferred, the clew blade 5 rotates once, and the notch 7
The material is pushed out by the raw material 20a transferred from the rear by the non-existing portion, and the pushed raw material is further transferred forward (FIGS. 4C and 4D). That is, according to this, the swelling of the raw material 20 on the upper portions of the screw blades 5 and 6,
The retention phenomenon can be eliminated, the retention time of the raw material 20 can be sufficiently taken, and the phenomenon that the raw material 20 is quickly transferred without retaining at all can be prevented.

がない。Further, as shown in FIG. 5, the raw material 20 pressed against the inner wall surface of the casing 1 is scraped off by the projections 10 and 11, and the friction of the raw material 20 against the outer peripheral surfaces of the screw blades 5 and 6 is caused by the projections 10 and 11. It is remarkably reduced compared to the one scratched on the entire outer peripheral surface. Therefore, the only measure against wear is protrusion 1.
It is only necessary to apply it to Nos. 0 and 11, and it is not necessary to protect the entire outer peripheral surfaces of the screw blades 5 and 6 with ceramic spraying, hardfacing, or the like.

Further, the shapes of the cutouts 7 and 8 and the protrusions 10 and 11 described in the embodiments are merely examples, and the shapes are not limited to these.

能になる等の優れた効果がある。Since the invention of claim 1 has the above-mentioned constitution, the residence time of the raw material can be sufficiently secured and the heating or cooling of the raw material can be favorably performed. In addition, the scraping of the raw material adhered to the inner wall surface of the casing with the scraper protrusion does not generate the force to press the raw material against the wall surface as in the case of scraping with the entire outer circumference of the scrape blade, so the raw material is easily scraped . Moreover, since it is only necessary to take measures against wear on the protrusions, the cost is low and the repair is easy. Furthermore, the clearance between the outer peripheral surface of the screw blade and the inner wall surface of the casing other than the protrusion for the scraper is increased, and the amount of friction is reduced.
There is an excellent effect that the driving torque of the screw shaft can be reduced.
