[0021] As an alternative to embodiment 1, the heating wire is spirally wrapped around the inner wall of the mixing drum 2, and the heating wire is wrapped with a high-temperature-resistant insulation layer.

[0022] In practical application,

[0023] I. Assembly of the device: First, build the main structure of the feeding drum 1 and the mixing drum 2, and ensure that the connection between the two is sealed and that the raw materials do not leak.

[0024] Install the double-shaft motor 4 on the feeding drum 1 and the mixing drum 2 at appropriate positions, and install two rotating shafts 5 in the feeding drum 1 and the mixing drum 2 respectively in a rotatable manner. Install the stirring paddle 6 on the rotating shaft 5. The stirring paddle 6 is designed in a spiral shape and coated with a wear-resistant coating on the blade surface to enhance the stirring effect and service life.

[0025] Install the auxiliary rotating shaft 7 on the feeding drum 1 and set the propeller 8 on the auxiliary rotating shaft 7. Connect the auxiliary rotating shaft 7 to the rotating shaft 5 inside the feeding drum 1 by belt drive. The belt drive uses synchronous belt drive, and a tensioning device is installed on the synchronous belt to ensure the stability and reliability of the transmission.

[0026] Install the heating wire in a spiral wrapping manner on the inner wall of the mixing drum 2, and wrap the heating wire with a high-temperature-resistant insulation layer to prevent the risk of electric leakage and short circuit, while ensuring uniform heating.

[0027] Install the base 9 at the bottom of the mixing drum 2 and set the conveying assembly on the base 9. The first conveying platform 10 in the conveying assembly is installed in alignment with the outlet end of the mixing drum 2, and the second conveying platform 11 is hingedly connected to the base 9 at one end and has its inlet end corresponding to the outlet end of the first conveying platform 10. Finally, install the angle adjustment telescopic rod 12 between the base 9 and the second conveying platform 11.

[0028] II. Device operation

[0029] Start the double-shaft motor 4, and the two outputs of the double-shaft motor 4 drive the rotating shaft 5 in the feeding cylinder 1 and the stirring cylinder 2, respectively.

[0030] With the rotation of the rotating shaft 5 in the feeding cylinder 1, the auxiliary rotating shaft 7 and the propeller 8 thereon are synchronously rotated through belt transmission. After the raw materials enter from the top of the feeding cylinder 1, the propeller 8 preliminarily stirs and pushes the raw materials, so that the raw materials move along the feeding pipeline to the stirring cylinder 2, preventing the raw materials from accumulating and clogging in the feeding cylinder 1.

[0031] The raw materials entering the stirring cylinder 2 are fully stirred and mixed under the action of the stirring paddle 6 driven by the rotating shaft 5. At the same time, the heating wires on the inner wall of the stirring cylinder 2 are electrified and heated to heat and process the raw materials in the stirring cylinder 2, so that the raw materials reach the required process temperature condition. For example, in food processing, some sauce raw materials are heated and stirred to make them uniformly mixed and reach the appropriate viscosity.

[0032] After the stirring and heating treatment, the raw materials flow out of the stirring cylinder 2 to the first conveying table 10. According to the actual production requirements, the length of the telescopic rod 12 is adjusted to change the inclination angle of the second conveying table 11, so that the raw materials are conveyed to the designated height and position, such as a higher storage tank or other processing equipment.

[0033] II. Working principle

[0034] Power transmission and raw material propulsion principle: the double-shaft motor 4 serves as a power source to provide power for the entire device. In the feeding cylinder 1, when the rotating shaft 5 rotates, the auxiliary rotating shaft 7 rotates through synchronous belt transmission, and the propeller 8 rotates accordingly. The rotation of the propeller 8 generates axial thrust and stirring effect on the raw materials entering the feeding cylinder 1. The axial thrust pushes the raw materials along the feeding pipeline to the stirring cylinder 2, and the stirring effect preliminarily mixes and disperses the raw materials during the feeding process, preventing the raw materials from caking or clogging the feeding cylinder 1.

[0035] Stirring and heating principle: when the raw material enters the stirring cylinder 2, the rotating shaft 5 drives the spiral stirring paddle 6 to stir the raw material. The spiral structure of the stirring paddle 6 produces flow in the radial and axial directions when rotating, achieving sufficient mixing and stirring. The lifting force generated by the rotation helps the raw material circulate in the stirring cylinder 2, ensuring uniform heating of the raw material. The spiral heating wire on the inner wall of the stirring cylinder 2 heats the raw material in the stirring process. The heat is transferred to the raw material through heat conduction and heat convection, raising the temperature of the raw material. Because the heating wire is spiral, the raw material at different positions in the stirring cylinder 2 can be heated relatively uniformly, achieving the desired heating effect and meeting the production process requirements for raw material temperature.

[0036] Conveying principle: the processed raw material in the stirring cylinder 2 falls onto the first conveying table 10 under the action of gravity, and then the angle of the second conveying table 11 and the base 9 is adjusted according to the angle set by the telescopic rod 12, so that the raw material is conveyed to the target position on the first and second conveying tables 10 and 11 under the combined action of gravity and friction. By changing the length of the angle-adjusting telescopic rod 12, the inclination angle of the second conveying table 11 can be adjusted, and thus the conveying height and distance of the raw material can be changed, adapting to different production layouts and discharge requirements.

[0037] The above description is only to illustrate the present application, and it should be understood that the present application is not limited to the above embodiments, and various modifications in accordance with the present application are within the scope of the present application.
