对流干燥机CDRY

传导 连续 空气

CDry是一种间接加热接触干燥机。固体通过从蒸汽加热的圆盘到施加在圆盘上的液体产品的热传导进行干燥。与其他接触式干燥器相比，其优势在于传热面高得多，同时所需空间小。与对流干燥机相比，接触干燥机有较低的热损失与温暖的排气气流。由此产生的蒸汽以高的水蒸气浓度被除去。这导致较低的蒸汽消耗比对流干燥机。液体从产品罐中泵入循环罐中。悬浮液/溶液然后通过循环泵泵送至各个进料管道。每个进料管将液体产品输送到加热的旋转圆盘的一侧。多余的液体流回循环罐。 The solvent contained in the liquid product (e.g. water) evaporates during one turn of the disc. The dried solid adhering to the heated disc is subsequently scraped off with knives. The degree of drying of the end product can be influenced by the speed of the discs. The resulting dry product is transported out of the dryer via the product discharge. It is also possible to concentrate liquids without producing a dry product. Depending on the material properties of the product in use, the dry material created can have different forms. The exact product behavior can be analyzed with the aid of a pilot plant in Allgaier’s testcenter
