概述 Descriptions
◎ 滾筒干燥機(jī)是一種內(nèi)加熱傳導(dǎo)型轉(zhuǎn)動(dòng)連續(xù)干燥設(shè)備。旋轉(zhuǎn)的滾筒 通過(guò)其下部料槽,粘附著一定厚度的料膜,熱量通過(guò)管道輸送至滾筒 內(nèi)壁,傳導(dǎo)到滾筒外壁,再傳導(dǎo)給料膜，使料膜中的濕份得到蒸發(fā)、 脫濕、使含濕分的物料得到干燥。干燥好的物料被裝置在滾筒表面 的刮刀鏟離滾筒,到置于刮刀下方的螺旋輸送器,通過(guò)螺旋輸送器再 將干物料集中、包裝。

■ 特點(diǎn) FeAtUres
◎ 熱效率高。因滾筒干燥機(jī)傳熱機(jī)理屬熱傳導(dǎo),傳熱方向在整個(gè)操作周 期中保持*,除蓋散熱和熱輻射損失外,其余熱量全都用于筒壁濕料膜 的蒸發(fā)上,熱效率可達(dá)70%-80%.
◎ 操作彈性大,適用性廣?？烧{(diào)整滾筒干燥機(jī)的諸多干燥因素。如進(jìn)料的 濃度、涂料料膜的厚度、加熱介質(zhì)的溫度、滾筒的轉(zhuǎn)動(dòng)速度等,都可以改 變滾筒干燥機(jī)的干燥效率,且諸多因素互無(wú)牽連。這給滾筒干燥操作帶來(lái) 很大方便,使之能適應(yīng)多種物料的干燥和不同產(chǎn)量的要求。
◎ 干燥時(shí)間短。物料的干燥周期一般只有10-300秒,適合于熱敏性物 料。若將滾筒干燥機(jī)設(shè)置在真空器中,則可在減壓條件下運(yùn)行。
◎ 干燥速率大。由于涂抹于筒壁的料膜很薄,一般在0.3-1.5mm,且傳 2 . 熱、傳質(zhì)方向*,料膜表面可保持20-70kg .H 2O/m h的蒸發(fā)強(qiáng)度。
◎ High heat efficiency. The principle of heat transfer of the roller drier is heat conduction and the conducting direction keeps uniform in the whole operation circle. Except heat loss of end cover and radiation loss, all heat can be used for evaporating the damp materials on the wall of the roller . The efficiency can reach 70-80%.
◎ large operation elasticity and wide application. various drying factors of the drier can be adjusted, such as concentration of feeding liquid,thickness of material film, temperature of heating medium,rotating speed of the roller etc.which can change drying speed of the drier.As these factors have no interrelations each other,it brings great convenience to drying operation.and makes it applicable to dry various materials and to meet different requirements of production.
◎ Short drying period.the drying period of materials is normally 10 to 300 seconds,so it is suitable for heat-sensitive materials.It also can be reducing pressure operated if it is put in vacuum vessel.
◎ Fast drying rate.As film of materials coated on the wall of the roller is very thin. Normal,thickness is 0.3 to 1.5 mm,plus directions of heat and matter transmitting are 2 . identical, the vaporing strength on the surface of the film can be 20-70 kg.H 2O/m h.

■ 應(yīng)用 ApplicAtion
◎ 適用于化工、染料、制藥、食品、冶金等行業(yè)液體或較粘稠物 料的干燥。
◎ It is suitable for drying liquid raw materials or thick liquid in the field of chemical, dyestuff, pharmaceutical, foodstuff, metallurgy industry and so on.
