The hot air and product are conveyed into the Disperser/Ventilator which breaks up large agglomerates and further completes the mixing process between hot air and product.The hot air and product then enter the vertical column and static classifier where the bulk of the drying takes place. Smaller particles dry immediately, and report to the outlet of the dryer to be conveyed onto the product collection system. The coarser, still wet product is retained in the dryer column until it dries, at which point it is conveyed to the dryer outlet. Large agglomerates tend to collide with each other, thus exposing the wet material to the hot air.Gas heating can be indirect via steam or hot oil or direct fired. Combustors can be designed for gaseous or liquid fuels with controls set up to meet IRI, FM or local standards. The system controls are set up to run in an either manual or automatic mode, with PLC’s used to control the start up and shutdown sequencing if desired.Statistics for our fluid drying equipment process Drying Process:Continuous, direct contact heat transfer from hot gas to productDrying Media: Air, Nitrogen, superheated steamInlet temperature range: 250 to 1,800Outlet temperature range: 180 to 240特点与优势 •干和去附聚物在一个单一的步骤 •粒子粒子碰撞达到优良的产品,而无需移动部件 •极短的停留时间,对温度敏感的产品 •占地面积小,建筑空间的要求^小化 •喷射研磨原则保持在潮湿的饲料颗粒分布存在 •静态分类^大限度地减少产品topsize •高效节能完整的定制设计的干燥系统 工艺说明 加热的低压空气注入通过一系列的喷嘴进入干燥机的干燥室下部 的切线上,建立一个高速循环流动的气体。也成角度的喷嘴,以便排气 每个喷嘴的影响以前的喷嘴的排气。高速粒子之间的碰撞 作为结果的碰撞气流以及自然扩展所产生的涡流发生 气体的喷射而。 材料传送到该系统为一个蛋糕,粉末,或backmized的淤浆,并输入通过旋转干燥器 阀,文氏管,或送纸器。水泥浆也可以被雾化直接在干燥器中时所需的。原料 进入循环热空气的上游侧的第一喷嘴,与离心力所产生的空气 浓缩的材料在喷嘴上方的区域。粒子的粒子碰撞立即开始,松团作用的材料,可以形成硬团聚之前。创建一个巨大的表面积 允许蒸发迅速发生,从而按压在一个非常短的时间内的空气温度。 离心力所产生的干燥机内的再循环气体,迫使较大的颗粒的 周壁。更细的材料的干燥器中的分类器的出口的内半径移向 所在的位置。优良的产品出口随着排气蒸汽干燥器。更大的颗粒或附聚物 再循环到喷嘴面积干燥器中进一步附聚和干燥。 干燥过程:连续直接接触 干燥介质:空气,氮气, 过热蒸汽 进样口温度范围:180至1800 F 出口温度范围:130?1600快 材料停留时间:0.5?2秒 铣削操作:气流粉碎原理, 低压气体喷流 缩写的应用程序列表: 藻酸盐 无定形二氧化硅 啤酒酵母 碳酸钙 硫酸铜 食品级纤维 除草剂 高岭土 金属氢氧化物 金属硬脂酸盐 金属氧化物 云母 有机颜料 药湖 聚合物 淀粉 滑石 乙酸异丁酯FEATURES & ADVANTAGES • Dry and de-agglomerate in a single step • Particle-to particle collisions achieve fine products without moving parts • Extremely short residence times for temperature-sensitive products • Small footprint minimizes building space requirements • Jet milling principles preserve particle distribution present in wet feed • Static classifier minimizes product topsize • Energy efficient complete Custom Engineered Drying Systems PROCESS DESCRIPTION Heated low pressure air is injected into the lower drying chamber via a series of nozzles that enter the dryer on the tangent, setting up a high velocity recirculating flow of gas. The nozzles are also angled so the exhaust of each nozzle impacts upon the exhaust of the previous nozzle. High velocity collisions between particles occur as a result of the colliding gas streams as well as the eddy currents generated by the natural expansion of the jet of gas. Materials are delivered to the system as a cake, powder, or backmized slurry and enter the dryer via a rotary valve, venturi, or feeder. Slurries can also be atomizes directly in the dryer when desired. The feed material enters the recirculating hot air upstream of the first nozzle, with the centrifugal forces generated by the air concentrating the material in the area above the nozzles. Particle-to-particle collisions begin immediately, deagglomerating the material before hard agglomerates can form. A tremendous amount of surface area is created allowing evaporation to occur quickly, thereby depressing air temperature in a very short period of time. Centrifugal forces are generated by the recirculating gases within the dryer, forcing the larger particles to the peripheral walls. Finer material is displaced towards the inside radius of the dryer where the classifer outlet is located. Fine product exits the dryer along with the exhaust gas vapor. Larger particles or agglomerates are recycled to the nozzle area dryer for further de-agglomeration and drying.
