The invention, including those consisting of an opening and closing part for opening and closing the outlet hole while moving the front and rear ends arranged between the hopper opening and closing part relates to a kneading apparatus with the automatic opening and closing means, more particularly the hopper and the extrusion means is a leakage hole formed in the bottom surface in the automatic opening and closing device mounted kneading apparatus, and install a switch for the drive motor on / Off to one side of said dough body portion, and transmitting the rotational force of the drive motor is driven according to the on / Off signal of the switch compressed air by generating, but securely fixed to the cylinder which automatically moves the opening and closing portion in the front and rear ends to the inner dough body portion, the cylinder receiving the rotary force of the drive motor and installed in the air occurs sudanreul dough body portion for generating compressed air, the air generated by the generation means to form the cylindrical body so that the compressed air is introduced, the rear end of the opening and closing parts Bonded and fixed, characterized in that coupling bar is configured such that the first operating infestation by the compressed air flowing into the interior of the cylindrical body.
According to the present invention hameuroseo installed to be operated for opening and closing portion for opening and closing the outlet hole of the hopper by operation, eliminates the need to catch a separate device in order to move the opening and closing part in the middle to create the food by hand, and can improve the sanitary condition of the food, the since the movement of the opening and closing portion is moved to the switch operation can improve the working efficiency of, and may also eliminates the need for mounting the handle so as to move the opening and closing portion expect an effect capable of ensuring a working space.
