Next, the operation of the first embodiment of the stirring heat transfer device according to the present invention will be described. The object to be treated such as the powder or granules or sludge supplied from the supply port 5 is generally operated by switching on the control panel or the like of the stirring heat transfer device A, which is separately installed, so that the rotation drive means 12 is operated. The hollow shafts 8a to 8d in the casing 1 are operated at a rotation speed of, for example, 4 to 15 (rpm) through the operation of the one and the other speed reduction mechanism bodies 10 and 10. Then, the heat exchange medium P such as steam or hot water or cold water is introduced from the heat exchange medium introduction pipe 14 into the hollow shape of the stirring plate 13 through the hollow portions 8e of the hollow shafts 8a to 8d. The object to be processed supplied into the casing 1 is a hollow stirring plate 13 arranged in series in a manner inclined with respect to the longitudinal axis direction of the hollow shafts 8a to 8d,
13 ... is stirred. On the other hand, the heat exchange medium P is circulated from the heat exchange medium inlet 4 arranged in the case body 3, flows into the through hole or the recess of the jacket 2, and the hollow portions of the hollow shafts 8a to 8d described above through the casing 1. 8e
In addition to the operation of the heat exchange medium P introduced into the hollow shape of the stirring plate 13, the object to be treated inside the casing 1 is heated or transferred.

The object to be processed is transferred from one end (front end) to the other end (rear end) of the casing 1 while being heat-exchanged by a series of inclined hollow stirring plates 13, 13. . However, since the plurality of hollow stirring plates 13, 13, 13 near the discharge port 7 are arranged in the longitudinal axis direction of the hollow shafts 8a, 8d, etc., that is, in the direction substantially perpendicular to the hollow shaft length. The horizontal surface of the front surface or the back surface has a function as a stopper when the object to be processed is transferred to the other end (rear end) of the casing 1, and the object to be processed is the hollow stirring plate. It is not pushed further back than 13, 13, 13 and is discharged from the discharge port 7 as a processed object or product, a dried product, or a cake.

As described above, as long as the switch-on operation of the stirring heat transfer device A is continued by, for example, a separately installed control panel, the object to be treated supplied from the supply port 5 is automatically and appropriately stirred and heated.

It is transmitted to the pulley 11c and the first pinion 10e. The pinion teeth 10h of the first pinion 10e have substantially the same diameter as the first pinion 10e and rotate at substantially the same high speed. Since the pinion gear 10k of the second pinion 10f meshing with the pinion tooth 10h has a longer diameter than the pinion tooth 10h, low speed rotation as the first step, that is, first step deceleration is performed.
The pinion teeth 10i of the second pinion 10f have substantially the same diameter as the second pinion 10f, and rotate at substantially the same first stage low speed rotation. Since the pinion gear 10l of the third pinion 10g meshing with the pinion tooth 10i has a longer diameter than the pinion tooth 10i, it rotates at a lower speed than the first step as the second step, that is, the second step deceleration is performed. . Although the pinion teeth 10j of the third pinion 10g have a slightly longer diameter than the third pinion 10g, the third pinion 10g

Since the reduction gear 10m of the first gear shaft 10a meshing with the pinion teeth 10j has an extremely longer major diameter than the pinion gear 10l of the third pinion 10g, the second stage gear is used. The low-speed rotation is executed at a slower third-stage low-speed rotation, that is, the third-stage deceleration. The operation of the third stage low speed rotation is to rotate the reduction gear 10m, that is, the first gear shaft 10a and the hollow shaft 8a at a low speed, and the rotation speed thereof is compared with the rotation speed of the initial-moving motor 11. For example, about 1/50 to 1/200, that is, 4 to 15
The rotation speed is reduced to about (rpm). Then, the reduction gear 10n provided on the second gear shaft 10b that meshes with the reduction gear 10m also rotates in the opposite rotation directions at the same gear speed, and rotates in conjunction with the hollow shaft 8b. Here, the reduction ratio is represented by the number of rotations (rpm) of the motor 11 with respect to the number of rotations (rpm) of the reduction gear 10m.
Various pinion teeth or pinion gears or first and second
By changing the diameter and pitch of the reduction gear or the like provided on the gear shaft, a suitable reduction can be obtained in the hollow shafts 8a and 8b.
