Steam Pipe Indirect Heating Dryer for chemical petroleum light industry metallurgy
Application of Steam Pipe Indirect Heating Dryer :
Heating pipes through steam pipe indirect heating dryer provides required heat for drying wet material which is one kind of heat conduction type drying equipment open type and closed type are included. It is widely applied in chemical petroleum light industry metallurgy building materials industries etc. Main difference between steam pipe indirect heating dryer and normal rotary dryer is that it equips with steam heating pipes inside of the cylinder 1-3 circles of pipes are installed in concentric circles inside of the dryer cylinder one end is installed above drainage separation chamber of pipes collecting box at the outlet of the dryer. The other end is installed on tube sheet of the ventilation head with thermal expansion structure. Seam hot water and other heat carriers are fed in through steam journal pipe and distributed to each heating pipe through pipes collecting box. While condensate water gathers at header because of dryer slope and then discharge at steam journal pipe. Material is dried by lifting and mixing of heating pipe and moved from higher side to lower side because of dryer slope. Finally it discharges at the end of discharge funnel. Water vapour goes out by induced draft fan or natural ventilation. If it is organic solvent after vaporization it can be recycled by seal system. Inert gas can be used repeatedly.
Performance features of Steam Pipe Indirect Heating Dryer :
1. The needed investment is only 1/6 of foreign import product.
2. The final moisture of the materials is ensured to be below 0.5%, making it the first choice of dry-mixed mortar and slag powder production line.
3. The self heat preservation heat efficiency of the cylinder can reach as high as over 70%, thus improving the heat efficiency by 35%.
4. The fuel can be coal, gas and oil, and it can be used for drying lump, granulous and powdery materials whose granularity is below 20mm.
5. Compared with monocular dryer machine, its floor space is reduced by about 50%, infrastructure investment reduced by about 50% and electricity consumption reduced by 60%.
6. The needed final water content index can be easily regulated according to customers’ requirement.
7. The temperature of the air out is low and the service life of the dust removing equipment is long.
8. It needs no rack wheel and pinion driving, but uses riding wheel for transmission.
Working Principle of Steam Pipe Indirect Heating Dryer :
Materials enter the inner side of the drum through the feeding device to realize current flow drying process, and then the materials enter the middle layer of the inner wall through the other end to realize counter current drying process. They are lifted in over and over in the middle layer which advance in two-steps forward and one-step back way. The three-drum dryers absorb heat from both inner drum and middle drum, which extend the drying time and realize the best drying condition. Finally, materials fall into the external layer of the drum from the other end of the middle layer, processing in a rectangle multi-loop way. The dried materials move quickly out of the drum under the hot air, while the wet ones remain because of their own weight. Materials are dried completely inside the rectangle shoveling plate and then cooled by the single drum cooler, thus finishing the whole drying process.

Through continuous exploration and practice, the company has developed the advantages of low investment, high efficiency, low operation cost, high product quality and convenient control and operation. The microwave frequency thawing equipment with microwave frequency of 915MHz and output power of 20kw-200kw is above. For food processing enterprises such as chain fast food industry in China, food thawing is provided, and the improvement of food thawing technology in China is also renewed. The benefit is not only "farsightedness", but also at the foot of the eyes. According to experts, the traditional food thawing are based on heat conduction method, material surface temperature is higher than the internal temperature in the thawing process, inevitably there will be drop loss, which will increase the business loss. If merchants use microwave dryer, Steam microwave Pipe Indirect Heating Dryer for chemical petroleum light industry metallurgy power, material temperature and transmission speed can be used to achieve adjustable linkage, and the overall heating process control advantages can greatly reduce material consumption and improve food utilization. In addition, as the microwave thawing only needs electricity, no need to consume a lot of water, in the low carbon era, this is not lost a recommended fashion trend.
microwave dryer is a new type of environmental protection drying method. When dry, Steam microwave Pipe Indirect Heating Dryer for chemical petroleum light industry metallurgy directly to the medium molecules converted into heat, because the Steam microwave Pipe Indirect Heating Dryer for chemical petroleum light industry metallurgy penetrating performance of heating medium and at the same time, no need to heat conduction, so the heating speed is very fast, the water content below 30% of the food, the drying speed can be shortened hundreds of times.
microwave dryer advantages of equipment
1, microwave dryer, short, fast
Conventional thermal sterilization is used to transmit heat from the surface of the food to the interior through heat conduction, convection, or radiation. It often takes a long time to get the germicidal temperature. The Steam microwave Pipe Indirect Heating Dryer for chemical petroleum light industry metallurgy is the direct interaction between microwave energy and microorganisms such as food and bacteria. The interaction between heat effect and non thermal effect can achieve fast warming and bactericidal action, and the processing time is greatly reduced. The sterilization effect of various materials is usually 3-5 minutes.
2, Steam microwave Pipe Indirect Heating Dryer for chemical petroleum light industry metallurgy low temperature sterilization keep the nutrition and traditional flavor The Steam microwave Pipe Indirect Heating Dryer for chemical petroleum light industry metallurgy is through special heat and non thermal effect sterilization, compared with conventional thermal sterilization, it can get the desired disinfection effect at relatively low temperature and short time. Practice shows that the general sterilization temperature can reach the effect at 75-80 degrees centigrade. In addition, microwave dryer processed foods can retain more nutrients and color, aroma, taste, shape and other flavors, and have puffing effect. For example, the vitamin C retained in vegetables treated by conventional heat treatment is 46-50%, while that in microwave treatment is 60-90%, while that in conventional heating is 58%, while that in microwave heating is 84%.
3 microwave dryer and Steam microwave Pipe Indirect Heating Dryer for chemical petroleum light industry metallurgy save energy Conventional thermal sterilization often has heat loss in the environment and equipment, and microwave is directly treated to food, so there is no extra heat loss. In addition, the conversion efficiency of the electric energy to the microwave energy is in the 70-80%, and the power is generally reduced to 30-50%.
