Description

Technical Field

[0002] At present, the single cone dryer is a drying equipment widely used in chemical, pharmaceutical, food and other industries. Its main features are simple structure, convenient operation and high drying efficiency. The single cone dryer is mainly composed of a conical container, the interior of which is usually heated by a jacket. The raw materials enter from the top of the dryer for drying.

[0003] The Chinese utility model with application number CN202321469234.1 discloses a single cone dryer for reducing material residue, including a working tank and a receiving mechanism, wherein a turning mechanism for turning and stirring the material is provided in the middle of the inner side of the working tank, and the receiving mechanism for layered processing is installed on both sides of the inner side of the working tank, and a scraping mechanism for removing the material is provided on both sides of the turning mechanism, and a heating mechanism for heating and drying is provided in the middle of the inner wall of the working tank. Compared with the existing device, the single cone dryer for reducing material residue can rotate together with the rotating shaft through the connecting frame and the scraper plate attached to the inner wall of the tank body, so that the tank wall can be scraped, so that the adhering material can be removed in time, reducing the possibility of material residue.

[0004] When the raw materials are dried using a single cone dryer, in order to determine whether the drying of the raw materials meets the standards, a small amount of sampling of the raw materials in the single cone dryer is required. However, when sampling is performed by opening the discharge port at the bottom of the single cone dryer, the raw materials at the bottom of the single cone dryer are closer to the side wall of the single cone dryer, so the drying effect is better, which may lead to misjudgment of the overall drying effect of the raw materials in the single cone dryer.
