The cavity 23 and the preheating pipe 30 in the present invention have the function of preheating and heat preservation, which improves the utilization efficiency of steam and reduces energy consumption.
 Preferably, the preheating pipeline 30 in this embodiment is a coiled tube arranged around the outer circumference of the inner tub 21 , so as to facilitate sufficient and rapid preheating of the inner tub 21 .
 Preferably, the preheating pipe 30 in this embodiment is arranged adjacent to the outer wall surface of the inner tub 21 , so as to quickly transfer the heat carried by the steam inside the preheating pipe 30 to the inner tub 21 . In the actual design process, the end of the preheating pipeline 30 in this embodiment is provided with a control valve. After the preheating is completed, it is convenient to discharge the condensed water in the preheating pipeline 30 to avoid condensed water remaining in the preheating pipeline. , in the process of heating the foodstuffs in the inner barrel 21, heat is absorbed to cause waste of heat.
 In this embodiment, the inner tub 21 is provided with a steam heating pipe assembly 40 which is independent of the inner tub 21. The steam heating pipe assembly 40 is connected to the steam inlet, so as to facilitate the delivery of steam into the inner tub 21, thereby facilitating the steaming of food materials in the inner tub 21. . The setting independent of the inner tub 21 here means that the steam heating tube assembly 40 will not move with the rotation of the inner tub 21, and the stationary steam heating tube assembly 40 can evenly deliver steam to the inner tub 21 during the rotation of the inner tub 21 The ingredients in the container are convenient for evenly cooking the ingredients.
 Specifically, the steam heating pipe assembly 40 in this embodiment includes an intake pipe 41 and an exhaust pipe 42, the intake pipe 41 extends along the axial direction of the inner tub 21, the exhaust pipe 42 is obliquely connected to the intake pipe 41, and the exhaust The outlet end of the pipe 42 is located above the intake pipe 41 . Through the function of the air inlet pipe 41, it is convenient to transport the steam to the center of the inner barrel 21, so that the ingredients in the inner barrel 21 can be evenly cooked;
 See you again figure 1 and figure 2 As shown, the bracket 10 in this embodiment includes a first side frame 11 and a second side frame 12 arranged at intervals. During installation, the bucket body 20 is rotatably installed between the first side frame 11 and the second side frame 12 . Of course, in other embodiments of the present invention, the first side frame 11 and the second side frame 12 of the bracket 10 can also be set as an integrated structure, instead of two independent side frames, as long as it is within the concept of the present invention The following other deformation methods are all within the protection scope of the present invention.
 In order to drive the barrel body 20 to rotate, the cooking device in this embodiment further includes a driving device 50, which is drivingly connected to the barrel body 20, so as to drive the barrel body 20 to rotate to fully cook the ingredients in the barrel body 20. Preferably, the driving device 50 in this embodiment is a driving motor. During installation, the first side of the barrel body 20 is installed on the bracket 10 through the support shaft 60, the second side of the barrel body 20 is installed on the bracket 10 through the sliding bearing seat 70, the drive motor is docked with the support shaft 60, and the drive motor rotates. It can drive the support shaft 60 to rotate, and then drive the barrel body 20 to rotate, the structure is simple and easy to realize.
The two ends of the inner barrel 21 in this embodiment are respectively provided with a material inlet 211 and a material outlet 212, and the connection line between the material inlet 211 and the material outlet 212 is perpendicular to the rotation axis of the inner barrel 21, which is convenient for avoiding the driving of the cooking device. device 50. Both ends of the inner barrel 21 are provided with a tapered structure 213, and the feed port 211 and the discharge port 212 are respectively arranged at the tip of the two tapered structures 213, which is convenient for putting materials into the inner barrel 21, and is convenient for putting the inner barrel 21 The ingredients of the food are completely discharged from the inner bucket 21.
 According to the above-mentioned structure, it can be known that the bracket 10 of the cooking device of the present invention supports and fixes the above-mentioned other parts, and has mechanical properties such as strength and rigidity required to ensure stable operation of the equipment.
 The drive motor is the power source for the barrel body 20 to perform the rotary motion.
 One end of the support shaft 60 is connected with the barrel body 20 , the other end of the barrel body 20 is connected with the sliding bearing seat 70 , and the support shaft 60 is assembled in the bearing fixed on the bracket 10 . When connecting, the coaxiality tolerance of the support shaft is within a reasonable range to ensure the smooth execution of the rotary motion. The axis of the support shaft 60 is coplanar with the centerline of rotation of the barrel body 20 and is perpendicular to each other through its midpoint. A heating medium passes through the support shaft 60, and the seals are reliable everywhere.
 The shape of the barrel body 20 in the present invention is in the shape of a waist drum. When rotating around the axis of the support shaft 60, the space at the bottom of the barrel body 20 is constantly changing, causing the material to turn irregularly, so as to destroy the formed material mass. The manholes at both ends of the barrel body 20 serve as the material inlet 211 and the material outlet 212, and a reasonable switching sequence ensures that the material goes in and out smoothly and protects the operator. The preheating pipeline 30 is arranged around the outer circumference of the inner barrel 21, and utilizes the principle of heat conduction to raise the product temperature of the material. Insulation material is added in the cavity 23 between the inner tub 21 and the outer jacket 22 to protect the environment in the inner tub 21 favorably. The steam heating pipe assembly 40 guides the working steam into the inner barrel 21 to directly process the materials.
 From the above description, it can be seen that the above-mentioned embodiments of the present invention have achieved the following technical effects:
 The cooking device of the present invention is a process equipment capable of reducing the amount of condensed water generated and avoiding the occurrence of material agglomeration during the cooking process. When working, when the material is put into the inner barrel, the material is indirectly heated by the principle of heat conduction, and no condensed water is formed in the material during this process. After the preheating is completed, steam is passed through the barrel to cook the material. During this process, the heat preservation function of the cavity of the barrel improves the utilization efficiency of steam and reduces energy consumption.
