The viscosity of the article: the viscosity of the article changes with the moisture content, the viscosity can make the article round into a block, and stick to the wall of the cylinder, after drying, it is easy to stick to the dust collector and the pipe. In order to deal with this achievement, the suspension type double cone rotary vacuum dryer developed by Changzhou Fanqun Drying Facilities Co., Ltd. adopted pneumatic vibration and complete installation.
Allowable measurement of the item: The allowable measurement is the lowest temperature that the item can accept. Exceeding this measurement will cause the item's valence to change, composite destruction or face change. Heat-sensitive foods can normally be taken within and outside ≤60℃.
Bulk density of goods: Bulk density of goods refers to the quality of goods in department volume. Because the article is a mixture of absolutely dry articles and moisture, the absolutely dry articles are often granular or powdery, because the moisture in the article is not the same as the gap between the particles of the absolutely dry article. Therefore, the bulk density of the original wet article and the article in the drying process is also very different, which must be paid attention to when preparing the raw material.
Slip angle of items: When stacking granular or powdery items, when the angle between the stack of items and the bottom surface increases to this position, the scene of the front items falling down will occur. The angle between the oblique and the bottom of a certain item is called the slip angle of the item. The slip angle is related to the composition, moisture content, particle size and viscosity of the article. Therefore, when designing and choosing a double-cone rotary vacuum dryer, the position of the cylinder and double-cone should be selected according to the slip angle of the article.
