The main shaft with shovels is regulated by frequency converter to achieve an optimal adjustment to the process. The special mixing elements rotate in the cylindrical drum, which is equipped with a heating/cooling jacket, and generate a three dimensional movement of the product (mechanically generated fluid bed). The resultant frequent contact of particles with the heat transfer surface reduces the drying times to a minium.Standard Configuration The product movement creates an intensive contact of individual product particles with the heated wall of the machine and at the same time treats the product as gently as possible. Rotating choppers, installed inside the drum, provide additional dispersion during possible product transition phases and are available as an option. Fine particles in the solvent vapours are collected by a pneumatically cleaned filter mounted on the machine and are returned to the product bed for drying.Range of Application End and intermediate pharmaceutical products Chemicals Recyling Different types of sludge Moulding, friction and fibre compounds Dyestuffs Plastics (fibre polymers) Agrochemicals Chemical specialities |
真空干燥設(shè)備的儀表盤讀值與真空室內(nèi)玻璃棒溫度表讀值不相同的緣故:通常情況下,電加熱真空干燥機(jī)選用先加溫式壁,再根據(jù)朝向壁的輻射源加溫鋼件的方式;那樣,控溫器溫度感應(yīng)器就能夠安裝在式外墻壁,控制器能夠一起接受熱對(duì)流、傳輸和輻射源。 與一般普通干燥機(jī)相比,真空干燥機(jī)具備以下優(yōu)勢(shì):1、對(duì)于不容易干燥的樣品,例如粉末或其他顆粒狀樣品,使用真空干燥法可以有效縮短干燥時(shí)間;2、與依靠空氣循環(huán)的普通干燥相比,粉末狀樣品不會(huì)被流動(dòng)空氣吹動(dòng)或移動(dòng);真空干燥機(jī)的結(jié)構(gòu)及工作原理;3、真空環(huán)境大大降低了需要驅(qū)除的液體的沸點(diǎn),所以真空干燥可以輕松應(yīng)用 假如程序流程是根據(jù)加溫隨后真空實(shí)際操作的,則加溫氣體為當(dāng)機(jī)械泵工作中時(shí),必定會(huì)給機(jī)械泵產(chǎn)生發(fā)熱量,造成機(jī)械泵溫度上升,進(jìn)而減少機(jī)械泵的高效率。 真空干燥機(jī)加溫后的汽體被正確引導(dǎo)到真空壓力表,真空壓力表會(huì)造成溫度。假如溫度超出真空壓真空干燥機(jī)是通過抽去包裝容器內(nèi)部空氣達(dá)到預(yù)定真空度后,去除容器內(nèi)部件水分的設(shè)備。干燥工作時(shí)候,罐內(nèi)處于真空狀態(tài),夾套通熱水(或蒸汽、導(dǎo)熱油)加熱,隨著罐體低速回轉(zhuǎn),物料在罐內(nèi)不斷上下、內(nèi)外成菱形軌跡運(yùn)動(dòng)并吸收蒸發(fā),水蒸汽通過真空管路連續(xù)不斷排出,達(dá)到物料干燥目的。在干燥混合物的同時(shí),按客戶要求內(nèi)置噴 我們研究了一種干燥方法,該方法可使皮革在真空干燥機(jī)下進(jìn)行干燥作業(yè)并依次拉伸以提高面積產(chǎn)量。真空干燥在低溫下提供快速的速度,這對(duì)于易受熱損壞的無(wú)鉻皮革是有利的,在真空干燥后添加切換動(dòng)作可以顯著增加面積產(chǎn)量。 使用統(tǒng)計(jì)實(shí)驗(yàn)設(shè)計(jì),我們制
