Also known as "pneumatic dryers," they are the simplest gas suspension dryers with the smallest footprint. A single operation provides mixing, heat transfer, and mass transfer to dry a solid. Residence time within the dryer is very short, usually less than three seconds, producing almost immediate surface drying.Moist, powdery, granular, or crystallized Wet solids discharged from centrifuges, rotary filters, and filter presses Small in particle size Reasonably dry, friable, and not sticky Due to the very rapid drying process, flash dryers are not suitable for diffusion-controlled drying processes. Figure 1 shows a typical drying curve as obtained in a fixed or fluidized bed; the constant drying-rate area where surface moisture is removed is ideal for the flash-drying operation. The process is strictly controlled by the heat input without a residence-time requirement; the drying occurs "in a flash".Relatively simple in operation Take little space Generally require lower capital investment than other types of dryers Excellent choice for processing heat-sensitive or easily oxidized feed materials Product inventory in the flash-drying system is very low Easy to change product or product grade with minimum downtime Control of the flash-drying process is very simple Control system responds very quickly to operational changes Flash drying systems are designed based on feed and product characteristics, available or permissible heating source, and operational safety requirements. Such systems can be designed in a closed-cycle arrangement suitable for evaporation of organic solvents rather than water. The drying gas is inert (typically nitrogen), and the solvent evaporated in the flash dryer is subsequently condensed.Reduced running cost. Continuous producation machine without human touch. Ideal replacement for tray drying of wet cakes. Extramely sticky/pasty wet cake can be handled . Particle size as fine as 500 mesh is achievable. Low residence time-minimum exposure to hear-ratains original product quality. On line particle size reduction-eliminating need of separate pulverizer. Fully automatic - needs little running attention. Negligible material dusting. No products degradation or charring . Proprietary design of disintegrator ensures uniform mixing of wet cake and hot air giving consistent and homogeneous powder quality. High volume processing Large filtering area of bag filter-reduced pressure drop -large savings in power consumption of blower. Measurement of pressure drops at various places facilitates easy troble shooting and maintenance.Our Flash Dryer is a versatile machine and ideal for wet/pasty press cakes. we list below industries where it can be used. Chemicals - Inorganic & Organic Pesticides and Agricultural Chemicals Dyestuff and pigments- Organic & Inorganic Fertilizers,mineral ore Concentrares,technical ceramics food industry,pharmaceutical industry , agricultural extracesTray DryerFlash Dryer 1. Batch Type Operation equipment. 1. Continuous Operation equipment. 2. Extensively labour oriented, as labour is required for changing, arranging trays, pulverizing etc. 2. No manual handling involved hence substantial saving in labour cost. 3. seperate purverizing operation needed. 3. Pulverzing and drying operation takes place simultaneously. 4. Due to considerable manual handling lot of material wastage and dusting takes place. 4. Negligible materail wastage and dusting takes place. 5. The material being stacked in layers in the tray, uniform heating is not quaranteed and hence variation in product quality , moisture content or the possibility of meterial in top layer getting charred exists.. 5. Material being disintegrated uniformaly and thorough mixing of hot air & feed in disintegrator , consistent product quality is ensured. 6. System effciency is low due to: -low inlet air temperature is required to avoid charring of material , hence low thermal efficiency.- Drying time is very high and much heat is wasted in the exhaust. 6.High system efficiency due to :- High inlet air temperature can be used due to unique design of cage mill type disintegrator.- Low pressure drops in various components,requiring less power for blowers.- High efficiency hot Air Generator.- Fully automatic plant. 7. Material has to be conveyed from dryer to purverizer,purverizer to bagging plant.This results in more manpower requirement and higher material wastage. 7.No material coveying needed.bagging plant can be installed directly below bag filter of flash dryer.對于已經工業化的閃蒸干燥設備,閃蒸干燥機理和設備結構并不難掌握,較困難的是針對具體物料調整設備結構以適應被干燥物料的要求。閃蒸干燥設備廠的技術人員多以學機械設備專業為主,他們常把閃蒸干燥設備視為純機械產品。專業的局限使其對物料的物性比較輕視,對物料性質掌握的缺陷導致設備不理想。所以一臺設計成功的閃蒸 真空干燥機的種類有很多,大致有以下幾種: 1.耙式真空干燥機 真空耙式干燥機是一種傳導傳熱干燥器。物料不直接與加熱介質接觸,適用于干燥少量的、不耐高溫和易于氧化的泥狀、膏狀? 污泥烘干機面臨污泥污染的獨家優勢。這些年,中國的環保作業獲得很大發展,國家投入了很多資金進行污水處置,但若是對污水處置的伴生物污泥不進行合理處置的話,又將會構成一個無窮的污染源,損害生態環境,在污泥處置中,堆積和填埋并不是好辦法,不只糟蹋金錢,并且糟蹋土地。這就需求一種污泥無害化處置和使用的技凈化熱風循環烘箱的故障分析與排除 熱風循環烘箱是利用電為熱源,用低噪音 耐高溫的軸流風機對熱交換器以對流的方式加熱空氣,熱空氣層流經烘盤與物料進行熱量傳遞。本設備 采用了百級凈化熱風循環層流凈化技術,備有電腦自控系統,溫度控制技術先進,滅菌干燥可靠,整機噪閃蒸干燥機傷害是指閃蒸干燥機設備運動部件、工具、加工件直接與人體接觸引起擠壓、碰撞、沖擊、剪切、卷入、絞繞、甩出、切割、刺扎等傷害。 用于淀粉干燥生產線中,干燥段主要是用楔形槳葉干燥機以及旋轉閃蒸干燥機組合成的干燥系統。其中旋轉閃蒸干燥機的進料系統是直徑為300mm×3000mm不 |
