一、工作原理与应用范围介绍

Introduction of Working Principle and Scope of Application

将物料放入箱体内的加热管架上的料盘内，然后抽呈真空状态。物料在真空状态下受热干燥，速率会大大加快，同时也节省了能源。物料在少氧、真空状态下脱水干燥出来的产品在色、香、味等方面优于有氧热风干燥。物料中排出的溶剂可通过冷凝器加以回收利用。

方形真空干燥机、圆形真空干燥机适用于状态不稳定物料以及热敏性物料的烘干脱水。由于真空箱内部与外界隔绝，干燥过程接触氧的机会比传统热风干燥少，能有效保护物料氧化的破坏作用。非常适用于回收溶剂的物料干燥以及在干燥工程中有排出有毒、有刺激性气体的物料的干燥与回收处理。属于静态干燥，故干燥物料的形体不会损坏。工作时将粉状、颗粒状、块状、膏糊物料以及浓缩液置于烘盘中进行烘干。该机为分批次间歇干燥生产方式。

       The materials to be dried are placed in the tray on the heating pipe frame in the oven, and the oven will be vacuumized. The drying speed under vacuum state will be increased, thus to save energy. The products dehydrated and dried in the mionectic and vacuum state will be better than that dried by hot air as to the color, smell and taste. The solvent discharged by the materials may be recycled by condenser.

        The square/round vacuum drier is applicable to the drying and dehydration of unstable and heat-sensitive materials. For the inside of vacuum chamber is isolated from the outside, the opportunity to contact with oxygen during the drying is less than that of traditional hot air drying, effectively protecting the materials from oxidative damage. It is applicable to material drying of recovered solvent, and drying and recycling of material with poisonous and irritating gas discharged during the drying. The shape of materials to be dried will not be damaged for it is static drying. The powder, particle, bulk and paste materials and concentrated solution will be placed in the baking tray for drying. The intermittent drying in batch is adopted by the equipment.
