干燥

Will be the world's first hot dry sludge treatment technology for the company are the United Kingdom Bradford. In 1910, the company developed the first transgenic kiln drying machine sludge and sludge applied to do the practice into the late 80's, sludge drying technology is gradually paying attention to people, sludge drying technology application and promotion, the promotion of the means of sludge treatment and disposal of the change, this change is mainly reflected in: landfill disposal of sludge prior to drying sludge treatment; the proportion of sludge disposal have been burning large improve; Do sludge Products used as a backland for sale, and other industries have been expanding.

世界上最早将热干燥技术用于污泥处理的是英国的Bradford公司。1910年，该公司首次开发了转窑式污泥干化机并将其应用于污泥干化实践，进入80年代末期，污泥干化技术逐渐为人们所重视，污泥干燥技术的应用和推广，促进了污泥处理处置手段的改变，这种改变主要体现在：污泥填埋处置前，要将污泥进行干燥处理；污泥焚烧处置比例得到了较大提高；干污泥产品作为土地回用的肥源出售，产业规模不断扩大等。

In the preparation of high purity barium carbonate , exist some problems related with metal oxide pollution, control of the amount of the material to be added, moisture content higher then the standard, etc.

为解决高纯碳酸钡生产干燥过程中金属氧化物的污染、入料量不易控制、成品水分超标等生产难题，通过对所用电动离心喷雾干燥机辅助设备、控制系统的改进及干燥状态参数的确定，使高纯碳酸钡产品质量明显提高，其中：w≤5？06，w(H2O)≤0.1%，完全满足PTC用户的要求。

The second stage is to rapidly lift the material to the top of barrel and scatter it in shape of umbrella., hot wind will blow around from the center of the bottom of the barrel.

普通干燥机干燥时，由于原料是静止的，热风穿透不充分，只在局部受热，原料易结块，造成堵塞，故无法达到全面干燥的效果。

Indirectly heating type is mainly suitable for the material with long period of decreasing-speed drying and heat-sensitivity, such as phosphorus fertilizer, congruity clunch and phosphor plaster.

间接加热型主要适用于降速干燥阶段较长的物料和热敏性物料的干燥如：硫铵、有机晶粒、沥青土等。复合加热型主要适用于粉状及较轻物料的干燥如：磷肥、调和粘土、磷石膏等。

The concentration of volatile compounds and the COD value of condensed water were also influenced by the hydrolysis and decarboxylation in this process.

实验结果表明，污泥在干燥过程中会释放出氨气、挥发性有机酸和烷烃等挥发性有机污染物，且升高温度能够降低干燥机出料含水率，并能够通过影响水解及脱羧反应从而增加干燥过程排放的气体量及冷凝水的COD值。

To use vacuum refrigeration drier for an experiment of Oolong tea drying,in which,the tea leaves were dehydrated within drier in low temperature.

采用真空冷冻干燥机进行乌龙茶干燥工艺试验，揉捻叶不经冻结，直接在干燥机内加低温干燥。

Where drying in vacuum over a desiccant is directed in the individual monograph, a vacuum desiccator or a vacuum drying pistol, or other suitable vacuum drying apparatus, is to be used.

要是按着单独文献报道中做真空干燥失重，应该使用这些文献中要求采用的真空干燥器、真空干燥枪或者其他的真空干燥设备。

The most favorite parameters for processing Yuxiangrousi are that the thickness of material is 5mm, the pressure of sublimation is 140Pa, the pressure of desorption is 30Pa, the temperature of heating board is 20℃ by orthogonal experiments.

通过正交试验得出真空冷冻干燥鱼香肉丝的最佳工艺：鱼香肉丝厚度5mm、升华干燥时真空度140Pa、解析干燥时真空度30Pa、解析时加热板温度20℃，影响工艺的主要因素次序为加热板温度、厚度、升华压力和解析压力；以及复水量在原含水量Aw的140%～150%、复水温度65～85℃、复水时间20～30min最好；最后建立数学模型验证干燥时间。

Machine speed, coating self-leveling coatings is short, thick, in order to achieve the same effect of drying, dry time identifying, temperature is higher; machine speed slow, coating leveling, coating it thin, dry period may be shortened, appropriate drying temperature can be reduced.

机速快时，涂层流平时间短，涂层就厚，为获得同样的干燥效果，干燥的时间要认、温度要高；机速慢，涂层流平时间长，涂层就薄，干燥时间可缩短，干燥温度可适当降低。

The kernel shrinkage took place evenly during dehydranon period with a shrinkage rateof 5. 7%一5. 8%;The seed coats shrinkage was, however, uneven, which may be the explanation of occurrence and development of warped plate. Seed volume shrinkage and plate warping took place almost simultaneously at late stage of dehydration.

干燥期间瓜籽种仁发生均匀收缩，收缩率为5.7%~5.8%；但种皮横径收缩率(8.7%)远大于纵径收缩率(4.7%)，种皮的非均匀收缩可能是干燥期间翘板发生与发展的主要原因，体积收缩与翘板几乎同步发生在干燥后期--降速干燥阶段的中期。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
