Conventionally, the kneading operation has been automatically controlled using programs developed by third parties. However, the major drawbacks have been their limited functionality, lack of correspondence to complicated controls, and high cost.

Toshin is now developing its own high-quality software for the control of the kneaders.

Menu for programmed automatic kneading

*	Rotating direction of the blades (normal - reverse)
*	Number of rotations of the blades (0 to 100%)
*	Time or heat termination
*	Air blow operation
*	Dust collecting cover operation (lifting - lowering)
*	Tank stumbling operation (stumbling - horizontal)
*	Pressure lid operation (lifting - cleaning - intermediate - lowering)

Registration of automatic operation program 99 patterns

Characters are used to register the product types. Therefore, the material being processed is identified easily.

Program setting

The program setting can be easily made using the touch panel.
The setting can be transferred after being input by PC (compact flash).

Kneading data registration

*	Electric current
*	Material temperature
*	Rotating velocity of the blades
*	Coolant inlet temperature
*	Coolant outlet temperature
*	Atmospheric temperature

The kneading data recording function is provided as standard.
The data is graphically shown on the panel.

*	Each data can be edited using Excel. The data can be transmitted via e-mail, facilitating the correspondence to the recipients' demand for traceability.
*	Needs for consumables, such as record chart sheets, recording pens, are reduced.

As standard, one shaft has two blades.
In case of "many wing", one shaft has two blades or more.
These blades were designed by enhancing conventional blades. The blades of "many wing" provide sufficient shearing force even when the rotating velocity is low, facilitating the temperature control.

Comparison test between two conventional 2 blades and 4 "many wing" blades

Material	-rubber 76% (Wt) + powder 24% (Wt)
Rotating velocity of the blades	-32rpm

2 blades		4 blades
Kneading for 1 minute and 30 seconds		Kneading for 1 minute and 30 seconds
*Not kneaded sufficiently
: :		: :
Kneading for 4 minutes, completed		Kneading for 4 minutes, completed
		*The material is being finely sheared and dynamically kneaded.

The seal of the blade shaft can be detached easily thanks to the hydraulic cylinder.
The cleaning can be done easily, preventing contamination when changing the compound.
Non-asbestos materials are used.
