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.

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. 干燥機選型一般會涉及這樣幾個問題：
1、 物料形態(tài)
干燥機選型主要是根據(jù)被干燥物料的形態(tài)來確定，物料形態(tài)不僅決定其干燥方式，同時對干燥機的 能用來進行農(nóng)藥干燥的農(nóng)藥干燥機，是干燥設(shè)備中的一種。農(nóng)藥干燥機在農(nóng)藥干燥處理中很常見也經(jīng)常使用到，所以對其進行熟悉和了解是非常有必要的，這樣我們才能正確應(yīng)用農(nóng)藥干燥機，并使農(nóng)藥良好的干燥。 1.選購時充分考慮相關(guān)因素 在選購農(nóng)藥干燥閃蒸干燥機熱空氣由SXG系列快速旋轉(zhuǎn)閃蒸干燥機入口管以適宜的噴動速度從干燥機底部進入攪拌粉碎干燥室，對物料產(chǎn)生強烈的剪切、吹浮、旋轉(zhuǎn)作用，于是物料受到離心、剪切、碰撞、摩擦而被除數(shù)微粒化，強化了傳質(zhì)傳熱。在干燥機底部，較大較濕的顆粒團在攪拌器的作用下被機械破碎，濕含量較低、顆粒度較小的顆粒被旋轉(zhuǎn)氣流實驗室離心噴霧干燥機傳熱快、水分蒸發(fā)迅速、干燥時間短的特點，且制品質(zhì)量好，質(zhì)地松脆，溶解性能也好，能改善某些制劑的溶出速率，適用于熱敏性藥物，此外，離心噴霧干燥機還可用于制備微囊。染料干燥廣泛采用的方法。將染料霧化而去除水分的干燥方法。適用于各類染料的干燥。可以干燥染料細粉、超細粉、無粉塵粉劑及空心 當我們在挑選農(nóng)藥干燥機時，除了物料的干燥特性外，還需要考慮許多其他因素。下面，就和小編一起來了解一下吧。 挑選農(nóng)藥干燥機的考慮因素： 1、物料的儲存和運輸方式 2、收集干燥產(chǎn)品的設(shè)備以及供熱輔助設(shè)備 |
