The invention provides a stirring structure in an integrated device for chitin production and belongs to the field of mechanical technology. According to the stirring structure in an integrated device for chitin production, the integrated device for chitin production comprises a fixed mount and a cylindrical shell arranged on the fixed mount. The upper end of the cylindrical shell is rotatably provided with a cover body. The stirring structure comprises a containing cylinder, a base plate and sidewall of which are both provided with through holes. The containing cylinder is rotatably arranged in the inner cavity of the cylindrical shell. A support shaft is fixedly connected inside the containing cylinder. The lower end of the support shaft is rotatably arranged at the central position of the bottom of the inner cavity of the cylindrical shell, and the lower end of the support shaft is detachably connected with the cylindrical shell. The stirring structure also comprises a rotary mechanism which is arranged on the cover body, is detachably connected with the upper end of the support shaft and drives the support shaft to rotate, and a gas transmission device which is arranged on the fixed mount and can transmit air to the bottom of the inner cavity of the cylindrical shell. The stirring structure of the invention has advantages as follows: stirring is convenient; raw materials are not easy to crush; and the stirring effect is good.
