In addition, it takes a long time to inject and drain the liquid, and a relatively long cleaning time.
Further, the cleaning nozzle 6 'is inserted into the processing tank 1' from the charging port 17 ', and the operator changes the jet direction of the cleaning liquid from the cleaning nozzle 6' to clean the processing tank 1 'and the rotary blade 2'. However, in this case, since it is inevitable that a blind spot is formed, the cleaning liquid does not reach every corner in the rotary blade 2 'and the treatment tank 1', and cleaning becomes insufficient. It was easy to end up.

Further, the construction of an attempt to improve the cleaning property in the conical stirring apparatus D ′ as described above has already been made, and a part of the processing tank 1 ′ can be freely opened and closed, and the processing tank 1 ′ is moved up and down. Alternatively, attempts have been made to facilitate cleaning by rotating or overturning or by dividing the treatment tank 1 ′ in the vertical or horizontal direction (see, for example, Patent Document 1).
However, in reality, even if such a configuration is adopted, it is difficult to thoroughly clean the inside of the rotary blade 2 'and the treatment tank 1', and the cleaning liquid scatters to the surroundings. Was not completely excluded.

The reservoir cleaning is performed with the operation posture completely positioned in the interior, and then the cleaning posture in which the rotor 2 is completely removed from the processing tank 1 as shown in FIG. It is also possible to perform the final cleaning by ejecting the cleaning liquid from the nozzle 6.
Here, in the reservoir cleaning, after the object to be processed is discharged from the discharge port 18, the cleaning nozzle 6 is attached to one or both of the lid 15 and the processing tank 1, and then the processing tank 1 is filled with the cleaning liquid. In this state, the rotating blades 2 are appropriately stopped and the inner surfaces of the rotating blades 2 and the treatment tank 1 are immersed in the cleaning liquid for an appropriate time. By performing such storage cleaning, most of the object to be processed is easily removed or peeled off from the inner surfaces of the rotor blade 2 and the processing tank 1, so that the amount of cleaning liquid used during finish cleaning is greatly reduced. In addition, the time for finishing cleaning can be greatly shortened.

[Example using a bellows body as a waterproof body]
Next, an example in which the bellows body 51 is used as the waterproof body 5 will be described. The configuration of the main body of the conical stirring processing device D is the same as that of the above-described embodiment, and therefore the description thereof is omitted here.

With the operation posture positioned at the position, a heating medium such as steam or hot water is supplied to the inflow pipe 13 to raise the temperature in the processing tank 1 and supply the object to be processed therein. At this time, the atmosphere in the processing tank 1 is set to a negative pressure by the action of the vacuum pump 103. Further, in this operating posture state, the cleaning nozzle 6 is not attached to either the lid 15 or the processing tank 1.
Then, the motor M is started to rotate the rotary blade 2, and the object to be processed is mixed and stirred by the action of the ribbon blade 23, and drying proceeds by receiving heat from the heat medium.
Thereafter, when the desired moisture value is reached or when a predetermined operation is performed, the discharge port 18 is opened, and the object to be processed is discharged.

(2) Cleaning operation Then, as the mixing / stirring / drying operation of the object to be processed by the conical stirring apparatus D as described above continues, the object to be processed adheres to the inside of the processing tank 1 and the rotary blade 2. Since this is unavoidable, the conical stirring apparatus D is cleaned every predetermined operating time or whenever the material of the object to be processed is changed.

It can be cleaned in a short time. In particular, in the case of this embodiment, the action portion of the cleaning liquid ejected from the cleaning nozzle 6 provided in the processing tank 1 moves in the vertical direction, and therefore, the rotation shaft 21 and the support bar are coupled with the rotation of the rotary blade 2. 22. The ribbon blade 23 can be washed evenly. For this reason, the number of installed cleaning nozzles 6 can be reduced.
Further, since the entire amount of the cleaning liquid after cleaning the rotor blades 2 is introduced into the processing tank 1, the inside of the processing tank 1 is also cleaned, and the total usage can be reduced by effectively using the cleaning liquid.
Furthermore, the amount of cleaning liquid, the setting of the cleaning time, and the like can be appropriately set by visually observing the degree of contamination and the cleaning state of the rotary blade 2 and the processing tank 1.
Further, since the cleaning liquid after cleaning the rotor blade 2 can be discharged together with the cleaning liquid after cleaning the processing tank 1, drainage management can be simplified.

When handling an object to be treated with high viscosity or adhesion, the reservoir cleaning is performed in the operating posture shown in FIG. 4A, and then the processing shown in FIG. As shown in (d), it is possible to perform finish cleaning while lowering the treatment tank 1.
