Description

Technical Field

[0002] With the widespread application of sweet potato starch in food, chemical industry, medicine and other fields, higher requirements are put forward for the quality and drying efficiency of sweet potato starch. Traditional sweet potato starch drying methods, such as natural drying, have the disadvantages of long drying time, great influence of weather, easy pollution and so on, which cannot meet the needs of modern production. Therefore, the research and development of efficient, energy-saving and environmentally friendly sweet potato starch drying equipment has become an inevitable trend in the development of the industry. The drying of sweet potato starch in the existing technology may rely on more manual operations, resulting in low production efficiency, and manual operations may bring errors and instability. Traditional screening methods may be inefficient and unable to effectively separate sweet potato starch of different particle sizes, affecting the uniformity of the product. The lack of automatic cleaning mechanism makes the discharge funnel and other components easy to be blocked and polluted, increasing the difficulty and frequency of manual cleaning. For this reason, we propose a sweet potato starch drying device. Utility Model Content

[0038] Working principle: The sweet potato starch is first evenly introduced into the spiral conveying device 1 through the discharge funnel 3. The design of the discharge funnel helps to control the flow of materials and avoid blockage or excessive input. The auger 7 in the spiral conveying device 1 is driven to rotate by the auger motor 11 to form a continuous conveying channel. The spiral blades of the auger 7 push the sweet potato starch forward and mix the materials at the same time to ensure uniform heating. During the conveying process, the electric heating sleeve 9 heats the sweet potato starch. The electric heating control cabinet 10 controls the heating power of the electric heating sleeve according to the preset temperature and time parameters to ensure that the sweet potato starch is gradually dried during the conveying process and remove excess moisture. The heated and dried sweet potato starch enters the screening device 2, which is mainly composed of a collecting box 17 and a screening box 19. A filter screen 23 is provided inside the screening box 19 to separate the sweet potato starch into fine material and coarse material. The vibration motor 20 drives the screening box 19 to generate high-frequency vibration, causing the sweet potato starch to form a jumping motion on the filter screen 23, thereby achieving screening. The fine material passes through the filter screen and falls into the fine material bin, while the coarse material remains above the screen and eventually falls into the coarse material bin. The springs 22 installed around the bottom of the screening box 19 act as a buffer, reducing the impact of vibration on the equipment while maintaining the stability of the screening. The cleaning component installed on the top of the discharge funnel 3 is responsible for removing the sweet potato starch attached to the inner wall. Powder, cleaning motor 16 drives rotating base 14 to rotate, drives connecting rod 13 and scraper 12 to rotate, scrapes off the residue on the inner wall, this step ensures the smoothness of discharge funnel, avoids the overall work efficiency being affected by blockage, the sieved sweet potato starch is stored in fine material bin and coarse material bin of collecting box 17 respectively, the fine material can be used for direct packaging or further processing, the coarse material may need to be reprocessed or used for other purposes, according to actual needs, the collected sweet potato starch can be packaged, stored or transported and other subsequent processing steps.
