中文拼音 [jiàngsùgānzào]
降速乾燥
英文
falling rate of drying-
The pulsed fluid beds can overcome these problems, especially for uneasily fluidized and special materials, and it has lower pressure drop, small fluidization velocity, height and saving energy etc
脈沖流化床乾燥器用來乾燥不易流化的物料和有特殊要求的物料,能有效克服上述弊端,且具有壓降低、流化速度小、床層高度小、節能等優點。Results showed that moisture content was mostly removed during sublimation period of freeze - drying, while rapidly dropped during earlier period of air - drying and gradually decreased during vacuum belt drying
結果表明:真空冷凍乾燥物料中的大部分水分在升華階段去除,熱風乾燥初期水分含量迅速下降,真空帶式乾燥物料水分隨時間延長呈比較均勻的下降。During the test, under the certain condition, the prototype can reduces the coal moisture from 20 % to 0. 5 %, the evaporate rate up to 22kg / ( m2. h ), laying a solid and reliable foundation for its industrialization
在試驗中,該機在一定乾燥條件下,可將煤中水分從20降至0 . 5 ,蒸發速率達到22kg ( m ~ 2 ? h ) ,為其工業應用奠定了可靠的理論與實驗基礎。The dehydration time is square of the droplets diameter so the small diameters of the droplets can cut down the drying time then reduce the height of the drying chamber. to the combined spin - flow pressure spray drying, the diameters of droplets are small and the dehydration rate is higher so keeping the qualities of the dried products we can increase the speed of the inlet wind and reduce the temperature of the outlet wind thus can improve the evaporation intensity of the drying chamber and the average energy utilization of the drying equipment
因霧滴的脫水時間與其直徑的平方成正比,減小液滴直徑有利於縮短乾燥脫水時間,可有效降低乾燥塔的高度;由於旋流式組合壓力噴嘴霧化滴徑的減小,脫水速度明顯加快,在不影響乾燥物料性質的前提下,適當提高進風溫度,同時有效地降低排氣溫度,有利於提高幹燥塔的蒸發強度,也有利於提高幹燥設備的平均能源利用率。Abstract : according to analysis of drying characteristics of granular product, the paper dscribed analytical solutions on a single grain with two falling rate drying stages during corresponding falling rate drying periods of deep - bed drying process the changes of drying and physical parameters , and their corresponding relation were discussed. a mathematical model was developed and analytical result was presented by computation. the potential application of this analytical solution was alsogiven in this paper
