[0025] Example 1
[0026] Please see Figures 1-6 This utility model discloses a heating device for food additive production with pretreatment function, including a drying cylinder 2, a hot air duct 21 installed on the side of the drying cylinder 2, and a pretreatment mechanism 1, a dehumidification mechanism 3, and a stirring mechanism 4, wherein:
[0027] The pretreatment mechanism 1 includes a treatment box 11 with an opening at the top. Symmetrically arranged crushing rollers 13 driven by a motor are installed inside the treatment box 11. A feeder 12 is connected to the bottom of the treatment box 11. The feeder 12 is connected to the drying cylinder 2 and is used to convey materials into the drying cylinder 2.
[0028] The stirring mechanism 4 includes a stirring motor 41 installed at the bottom of the drying cylinder 2, and the output shaft of the stirring motor 41 extends into the drying chamber and is equipped with a stirring frame 42.
[0029] The dehumidification mechanism 3 is located at the upper part of the drying chamber and is used to drain the moisture inside the drying chamber.
[0030] Please refer to the appendix. Figure 2 , Figure 3 The processing box 11 has a slot 14 located at the lower end of the crushing roller 13 in the middle. A screen 15 is movably connected in the slot 14. The screen 15 is located at the lower end of the crushing roller and corresponds to the crushing roller 13.
[0031] Specifically, the rotating crushing roller 13 inside the processing box 11 crushes the material passing through the crushing roller 13, causing the adhering or large particles in the material to be crushed and dispersed. The dispersed material falls above the screen 15 and passes through the screen 15 into the conveying cylinder 122.
[0032] Furthermore, the feeder 12 includes a conveying cylinder 122, which is connected to the top of the drying cylinder 2 and has a spiral conveying blade 124 driven by a drive motor 121 installed inside. The upper end of the conveying cylinder 122 is equipped with a feeding seat 123 connected to the bottom of the processing box 11.
[0033] Specifically, the drive motor 121 drives the spiral conveyor blades 124 to rotate, conveying the material entering the conveyor cylinder 122 to the drying cylinder 2.
[0034] Please refer to the appendix. Figure 6 The bottom of the drying cylinder 2 is provided with a discharge port 44, and a discharge cylinder 45 is installed at the bottom of the discharge port 44. A sealing plate 43 extending to the discharge port 44 and closing the discharge port 44 is movably inserted into the side end of the drying cylinder 2.
[0035] Specifically, after drying is completed, the sealing plate 43 is pulled out, and the material is discharged from the discharge port 44.
[0036] Example 2
[0037] Based on the above embodiment 1, please refer to the appendix. Figure 2 , Figure 5 The dehumidification mechanism 3 includes an isolation net 33 installed inside the drying cylinder 2. The isolation net 33 is located at the upper end of the conveying cylinder 122. An upward-facing water receiving trough 32 is installed at the center of the isolation net 33. A condensation platform 31 corresponding to the water receiving trough 32 is installed at the top inside the drying cylinder 2.
[0038] Furthermore, the condensing platform 31 is conical, and a condensing plate 311 corresponding to and cooperating with the water receiving tank 32 is installed on the outer wall of the condensing platform 31. A drain pipe 34 is installed inside the water receiving tank 32, and the drain pipe 34 passes through the water receiving tank 32 and the drying cylinder 2 and extends to the outside of the drying cylinder 2.
[0039] In this embodiment, the moisture in the material is dried into water vapor. When the water vapor floats upward to the condensation platform 31, it comes into contact with the condensation plate 311 and condenses into water. The condensed water flows downward along the condensation plate 311 and finally drips into the water receiving tank 32. The water in the water receiving tank 32 is finally discharged from the drying cylinder 2 through the drain pipe 34.
[0040] The working principle and usage process of this utility model are as follows: Food additive materials (hereinafter referred to as materials) are poured into the processing box 11 from top to bottom. The crushing roller 13 inside the processing box 11 rotates to crush the materials passing through the crushing roller 13, so that the materials that are stuck or have large particles are crushed and dispersed. The dispersed materials fall above the screen 15 and pass through the screen 15 into the conveying cylinder 122. The drive motor 121 drives the spiral conveying blades 124 to rotate and convey the materials to the drying cylinder 2, thus completing the pretreatment of the materials.
[0041] The material entering the drying cylinder 2 falls to the bottom of the drying cylinder 2. At this time, the hot air pipe 21 delivers hot air into the drying cylinder 2 to dry the material. At the same time, the stirring motor 41 drives the stirring frame 42 to rotate, continuously stirring and turning the material, so that the material can fully contact the hot air for drying. At this time, the moisture in the material is dried into water vapor. When the water vapor floats upward to the condensing platform 31, the water vapor comes into contact with the condensing plate 311 and condenses into water. The condensed water flows down along the condensing plate 311 and finally drips into the water receiving tank 32. The water in the water receiving tank 32 is finally discharged from the drying cylinder 2 through the drain pipe 34. Finally, the sealing plate 43 is pulled out, and the material is discharged from the discharge port 44, completing the drying operation.
