FIG. 1 is a simplified front view of a pan in a first embodiment of a rotary stir-fry apparatus according to the present invention. It is a simplified front view of a pot in a 2nd example of a rotary type frying and roasting device concerning the present invention.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  The apparatus according to the present invention performs stir-fry cooking or roasting well in a short time and evenly by controlling the power of the burner heating the pan while automatically rotating the pan based on the temperature of the pan. However, in the present embodiment, the rotary frying and roasting apparatus in the form of supporting the pan sideways is supported as a representative example, but the present invention is not limited thereto, and the central axis of the pan is inclined. It is possible to provide a rotary frying / roasting device in a form to support or a form to support in a state where the pot is stood upside down.

  The pot 11 has a substantially cylindrical shape with one end being a closed end and the other end being a material receiving port 12, and the material receiving port 12 is turned over so that it is on the left side in the drawing. The pan 11 is formed of a conductive member, and is preferably a lightweight member such as stainless steel. In addition, a pan lid (not shown) is put on the material receiving port 12 during operation of the rotary stir-fry and roasting apparatus.

  Further, the pan 11 is disposed at the lower part of the outer peripheral surface near the material inlet 12 of the pan 11 and rotatably supports the pan 11, and the cylindrical closed end outer axial center extension of the pan 11 It is rotatably supported by a hollow shaft 1 cantilevered on a line. The hollow shaft 1 is rotatably supported by a flange type bearing 14 attached to a housing 40 and is inserted through a hollow chain / sprocket 15 and a cylindrical slip ring 5. The slip ring 5 is provided with a metal brush 50. Reference numeral 51 denotes a lead wire connecting the metal brush 50 and the temperature controller 53.

  When the motor 20 rotates, the force of the motor 20 is transmitted to the chain / sprocket 15 via the pan rotation drive chain 21 to rotate the hollow shaft 1. Since the pan 11 rotatably supported on the hollow shaft 1 is integrally fixed to the shaft center in common, the pan 11 also rotates when the hollow shaft 1 rotates.

  The pan receiving roller 13 is formed of a conductive material, and a lightweight member such as, for example, stainless steel is desirable. Moreover, the pan receiving roller 13 is supported by and attached to the housing 40.
