DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Embodiment 1

[0022] When drying protein powder, the drying device in the prior art uses a stirrer to stir the protein powder synchronously, but a part of the protein powder still contacts the cylinder wall of the heating device for a long time, which not only affects the uniformity of heating of the protein powder, but also leads to poor drying effect. Figure 1-Figure 4 As shown, this embodiment proposes a soy protein powder drying device, which can effectively improve the uniformity and efficiency of protein powder drying. A drying cylinder 2 is fixedly installed on a mounting frame 1 of the device, and a heating plate is arranged inside the side wall of the drying cylinder 2. After power is turned on, the side wall of the drying cylinder 2 will generate heat, so as to quickly heat the scattered and fallen protein powder. A material dispersing mechanism 3 for breaking up and drying the protein powder is provided on the drying cylinder 2, and a cooling and discharging mechanism 4 for receiving the material is provided below the drying cylinder 2. Before the protein powder enters the drying cylinder 2, it will be crushed and broken up by the action of the material dispersing mechanism 3. After drying, the protein powder will fall onto the cooling and discharging mechanism 4 and finally be discharged.

[0023] In order to disperse the protein powder as much as possible during the falling process and improve the efficiency and uniformity of heating, the present embodiment is provided with a material dispersing mechanism 3. Specifically, the material dispersing mechanism 3 comprises a rectangular shell 301 detachably mounted on the upper end of the drying cylinder 2, a feeding funnel 302 is fixedly mounted on the upper end of the rectangular shell 301, a rolling roller 303 is symmetrically arranged inside the rectangular shell 301, and a plurality of convex strips are evenly spaced outside the rolling roller 303, which can effectively improve the crushing effect of the rolling roller 303 on the protein powder. A bulk material mesh plate 304 is coaxially movably installed on the part, and an annular baffle is arranged at the edge of the upper end of the bulk material mesh plate 304 to prevent the protein powder from falling downward from the side when the bulk material mesh plate 304 is shaken; a fixed boss 305 is arranged on the inner wall of the drying cylinder 2, and an exciter 306 for vibrating the bulk material mesh plate 304 is arranged on the fixed boss 305; a discharge circular pipe 307 is connected to the bottom of the drying cylinder 2; after the protein powder enters the feed funnel 302, it will first be rolled by the rolling roller 303, so as to break up a small amount of agglomerated protein powder.

[0024] In order to quickly dissipate the heat remaining in the protein powder after drying and avoid the deterioration of the protein powder after bagging, the present embodiment is provided with a cooling and discharging mechanism 4. Specifically, the cooling and discharging mechanism 4 includes a mounting seat body 401 symmetrically arranged on the mounting frame 1, and each mounting seat body 401 is respectively installed with a feed circular shaft 402, and a conveyor belt 403 is arranged between the two feed circular shafts 402. An inclined scraper 404 is fixedly installed on the outside of the drying cylinder 2. The protein powder after drying will fall onto the conveyor belt 403 through the discharge circular tube 307, and then the protein powder will move synchronously with the conveyor belt 403, so as to realize automatic material connection. The inclined scraper 404 is located above the conveyor belt 403, and the inclined scraper 404 is close to the conveyor belt 403 but not in contact with it. When the conveyor belt 403 moves, the inclined scraper 404 will scrape the protein powder accumulated on the conveyor belt 403 flat.

[0025] In the present embodiment, when in use, the staff will pour the protein powder to be packaged into the interior of the feed funnel 302, and then the protein powder will fall between the two rolling rollers 303 through the feed funnel 302. If there is no agglomeration inside the protein powder, it will directly fall into the interior of the drying cylinder 2 through the rectangular shell 301. If the protein powder agglomerates inside due to moisture absorption, the rolling rollers 303 in a rotating state will automatically crush the agglomerated protein powder, and the crushed protein powder will also fall into the interior of the drying cylinder 2.

[0026] After the protein powder enters the interior of the drying cylinder 2, it will fall onto the top of the bulk material mesh plate 304. At the same time, the bulk material mesh plate 304 will be in an irregular vibration state under the action of the vibrator 306. When the bulk material mesh plate 304 vibrates, the protein powder will be scattered and fall downward. During the falling process, the drying cylinder 2 will dry the protein powder.

[0027] Subsequently, the dried protein powder will fall onto the conveyor belt 403 through the discharge tube 307 and move synchronously with the conveyor belt 403. During the movement, the inclined scraper 404 will spread the protein powder accumulated on the conveyor belt 403, so that the heat inside the protein powder can be quickly dissipated to prevent the protein powder from deteriorating.

[0028] The present embodiment provides a material dispersing mechanism 3, and utilizes the mutual cooperation between the rolling roller 303 and the bulk material mesh plate 304, so that the protein powder can fall downward in the drying cylinder 2 in a dispersed form, which can effectively improve the efficiency of protein powder drying, and prevent a part of the protein powder from being burnt due to long-term contact with the cylinder wall, thereby improving the drying effect; moreover, the present embodiment provides a cooling and discharging mechanism 4, and utilizes the mutual cooperation between the conveyor belt 403 and the inclined scraper 404, so that the protein powder accumulated on the conveyor belt 403 can be automatically spread out, so that the heat inside the protein powder can be quickly dissipated, which can not only help the subsequent packaging operation, but also effectively prevent the protein powder from deteriorating.

[0029] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.
