製造することは困難であつた。"Problems to be Solved by the Invention" In the conventional vacuum granulation apparatus described above, when a binder solution is added by spraying, depending on the properties of the material, the material may easily adhere to the inner surface of the main body.
Since the granules that are being formed often adhere to each other, resulting in oversized granules, there is a limit to the material powder that can be granulated, and it has been difficult to produce granules with uniform granules in large quantities.

スペースを広く要する等の欠点があつた。 In addition, conventional equipment does not have coating or drying functions, and for coating or drying, the granulated granules must be taken out of the container and transferred to coating equipment or drying equipment, which takes a long time in the manufacturing process. In addition, each of the processes of granulation, drying, coating, and drying must be carried out in separate apparatuses, which has the disadvantage of requiring a large installation space for the series of apparatuses.

機構を設けたものである。"Means for Solving the Problems" In order to achieve the above-mentioned object, one of the vacuum granulation apparatuses according to the present invention, in the above-mentioned apparatus having a conventional structure, swings or horizontally granulates the spherical container. The drive mechanism is provided with a drive mechanism that alternately rotates a predetermined angle in forward and reverse directions with respect to a rotation center.

定量の材料を容器に投入し、撹拌羽根を回転させ
ると材料が混合ないし練合される。"Operation" According to the vacuum granulation apparatus according to the present invention described above, when a predetermined amount of materials is put into a container and the stirring blade is rotated, the materials are mixed or kneaded.

転に伴なう材料の転動によるものであるが、容器
の揺動又は正逆交互の回転がこれをより円滑にな
るように補助する。 This granulation action in a narrow sense is mainly due to the rolling of the material as the stirring blade rotates, but the rocking of the container or the alternating forward and reverse rotation assists in making this more smooth.

ないし練合した材料の容器本体内面への付着が防
止され、形成されつつある粒相互の付着も極めて
抑制される結果、円滑に造粒が行なわれる。 That is, as the container is rocked or rotated alternately in forward and reverse directions, the material flows alternately in the opposite direction to the rocking or rotating direction due to the action of gravity. As this movement and the movement caused by the rotation of the stirring blade are constantly applied to the material in a superimposed manner, the material or the particles being granulated roll in various directions in a complicated manner. This prevents crowding or adhesion of the kneaded material to the inner surface of the container body, and also extremely suppresses adhesion of particles that are being formed to each other, resulting in smooth granulation.
材料の性状によつては、さらにスクリユー羽根
を高速回転させて材料に風を送りながら造粒すれ
ば、材料の容器本体内面への付着や造粒されつつ
ある粒相互の付着がよりよく防止される。 Depending on the properties of the material, if the screw blades are rotated at high speed to blow air through the material during granulation, it may be possible to better prevent the material from adhering to the inner surface of the container body and the particles being granulated from adhering to each other.

動きは、前述の狭義の造粒中におけるそれと全く
同じであり、したがつてその作用も同じである。 When granulation is completed, the inside of the container is maintained at a predetermined reduced pressure and temperature, and the container is dried by rotating the stirring blade while rocking or rotating the container in forward and reverse directions as described above. The movement of the grains during this drying is exactly the same as that during granulation in the narrow sense described above, and therefore the action is also the same.
粒が乾燥したならば、容器内を所定の減圧状態
及び温度に保ち、容器を前述のように揺動又は正
逆に回転させながらコーテイング液をスプレー装
置により供給する。 Once the grains have dried, the inside of the container is maintained at a predetermined reduced pressure and temperature, and the coating liquid is supplied by a spray device while the container is rocked or rotated in forward and reverse directions as described above.
コーテイング後、容器内を所定の減圧状態及び
