[0002] Drum scraper dryers are suitable for drying liquid materials into powder or flakes. However, for high-sugar and high-viscosity liquid materials, conventional drum scraper dryers cannot completely scrape off the material after drying, resulting in a thicker and thicker layer of material sticking to the walls. Ultimately, the material cannot be dried or becomes scorched, making it impossible to operate stably for a long time.

[0003] In view of this, we have launched a special drum scraper dryer for high sugar and high viscosity materials. Utility Model Content

[0004] The purpose of this invention is to provide a special drum scraper dryer for high-sugar and high-viscosity materials to solve the problems mentioned in the background art.

[0018] Preferably, the surface of the scraper is provided with through holes at equal intervals for fixing. The through holes may be used to reduce the weight of the scraper, optimize the structural strength of the scraper, and facilitate installation.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] (1) By using a special anti-stick roller with a special scraper, the feeding method of extrusion coating combined with the scraper and scraping part effectively solves the problem that high sugar and high viscosity materials are difficult to scrape clean after drying, and the thickening of the sticky material on the wall causes the material to not be dried or burnt, so that the equipment can operate stably for a long time.

[0021] (2) By using a uniform feeding method and an efficient drying and scraping process, the material is heated evenly during the drying process, avoiding quality degradation caused by local overheating, ensuring the stability of material quality, and producing products with better quality.

[0022] (3) The heating tube is located inside the anti-stick drum, which can directly heat the material on the surface of the drum, improving the heat utilization rate. The vent is located at the top of the cover, which facilitates the discharge of water vapor and avoids the accumulation of water vapor inside the equipment, which affects the drying effect. The design of the return port allows the material that is not completely dried to participate in the drying process again, reducing material waste and improving production efficiency.
