Description

Technical Field

[0001] This utility model belongs to the technical field of yam powder production equipment, specifically relating to a dryer for yam powder production. Background Technology

[0002] Yam powder production requires crushing and drying. Current technology involves pulverizing, mixing, and drying the various materials before packaging. This process uses a crusher and dryer in two separate steps, with crushing preceding drying. To improve yam powder quality, an expansion step is added between the mixing and drying steps. The expanded material is in continuous strip form and needs to be crushed again after drying. Existing dryers cannot meet the requirements of continuous drying and crushing. Therefore, a dryer for yam powder production is urgently needed to solve these technical problems. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by providing a dryer for yam powder production. The dryer includes a drying chamber containing a conveyor. A crusher is installed at the discharge port of the dryer, with the discharge end of the conveyor extending into the crusher's casing. A receiving box is connected to the discharge port of the crusher, and a guide pipe is located at the bottom of the receiving box. This dryer is mainly used for drying and crushing yam powder after the puffing process. The material from the puffing machine enters the conveyor surface and is transported from the feed port of the drying chamber into the dryer for drying. After drying, the material is transported to the discharge port and falls into the crusher. The crushed material enters the receiving box and is discharged by the guide pipe to the next process.

[0004] Preferably, the crusher is a double roll crusher.

[0005] Preferably, the conveyor is a mesh belt conveyor. This can improve the drying effect and efficiency of the material.

[0006] Preferably, the drying oven has a material guiding assembly at its feed inlet. The material guiding assembly includes a horizontally arranged screw and a guide rod. Both ends of the screw are rotatably connected to brackets via bearings. The two brackets are fixed to the frames on both sides of the conveyor. One end of the screw is connected to a reversible motor. Both ends of the guide rod are fixedly connected to the corresponding brackets. The screw has two threaded sliders, each with a guide hole. The guide rod passes through the two guide holes. A horizontal roller is provided between the two sliders. Both ends of the horizontal roller are rotatably connected to the sidewalls of the corresponding sliders via bearing one. A vertical roller is provided on the upper surface of the two sliders. The lower end of the vertical roller is rotatably connected to the corresponding slider via bearing two. This setup allows for the smoothing of continuous strip-shaped materials after extrusion in the extruder, ensuring a more uniform distribution on the conveyor and improving drying efficiency. Specifically, the material passes between two vertical rollers and is placed on the conveyor. The motor drives the screw in both forward and reverse directions, causing two sliders to reciprocate along the screw, resulting in a wave-like distribution of the material on the conveyor surface. This improves the utilization rate of the conveyor surface, further enhancing drying efficiency and subsequent crushing efficiency. During this process, the friction generated when the strip-shaped material contacts the two vertical and horizontal rollers is rolling friction, which does not affect the movement of the material or break it.

[0007] Preferably, the feed end of the conveyor extends from inside the drying chamber, and the material guiding assembly is located above the conveyor outside the drying chamber, which is more conducive to feeding. Working principle: The continuous strip-shaped material discharged from the extruder passes between two vertical rollers and is then placed on a conveyor. The conveyor transports the material into the drying chamber for drying. The motor drives the screw to rotate in both directions, and the two sliders reciprocate along the screw, causing the material to be distributed in a wave-like pattern on the conveyor surface. This improves the utilization rate of the conveyor surface and further enhances the drying efficiency. After drying, the material is transported to the discharge port and falls into the crusher. The crushed material enters the receiving box and is discharged by the guide pipe to the next process.

[0008] This invention has the following advantages: it can continuously and effectively dry and crush materials after drying, with high crushing efficiency and good effect; when the material enters the drying box, it can be sorted to make its distribution on the conveyor more uniform, thereby improving the drying efficiency and subsequent crushing efficiency.

[0013] Example 1 like Figure 1 As shown, this utility model provides a dryer for yam powder production, including a drying chamber 1, a conveyor 5 inside the drying chamber 1, and a crusher 2 at the discharge port of the dryer. The discharge end of the conveyor 5 extends into the casing of the crusher 2, and a receiving box 4 is connected to the discharge port of the crusher 2. A guide pipe 11 is provided at the bottom of the receiving box 4. This dryer is mainly used for drying and crushing after the puffing process in yam powder production. The material 10 from the puffer enters the conveying surface of the conveyor 5 and is transported from the inlet of the drying chamber 1 into the dryer for drying. After drying, it is transported to the discharge port and falls into the crusher 2. The crushed material 10 enters the receiving box 4 and is discharged by the guide pipe to the next process.

[0014] The crusher 2 is a double-roll crusher 2, and the material 10 entering the crusher 2 is crushed by the crushing rollers 3 of the crusher 2.

[0015] The conveyor 5 is a mesh belt conveyor. It can improve the drying effect and efficiency of the material 10.

[0016] Example 2 like Figure 2-4As shown, the difference between this embodiment and Embodiment 1 is that a material guiding assembly is provided at the feed inlet of the drying box 1. The material guiding assembly includes a horizontally arranged screw 8 and a guide rod 9. The two ends of the screw 8 are respectively rotatably connected to brackets 6 through bearings. The two brackets 6 are respectively fixed on the frame on both sides of the conveyor 5. One end of the screw 8 is connected to a reversible motor 12. The two ends of the guide rod 9 are respectively fixedly connected to the corresponding brackets 6. Two sliders 13 are threaded on the screw 8. Each slider 13 is provided with a guide hole.
