Under a severe sludge treatmentand disposal situation in China, Biotechina, under the leadership of Dr. LiGuowen, after years of exploration and innovation, has mastered the coretechnology of Sludge Low-temperature Drying Process and been granted theInvention Patent No. 201310556663.7(a System and Process for SludgeLow-temperature Drying Treatment). The innovative sludge ultra-low temperaturedrying machine of Biotechina, by fully absorbing the essence of foreignadvanced equipment and also by innovating and making breakthroughs based onBiotechina’s years’ scientific achievements as well as its  rich engineering experiences of 18 years, has6, among others, major advantages, ie. advancedness, safety, reliability, high degreeof systematic level, high degree of equipment integration level and reasonablespace arrangement. Biotechina’s ultra-low temperature drying machine completelysolves the technical defects (high energy consumption, low efficiency, odoremission, flying dust, large footprint, low equipment integration level)in thecourse of drying treatment by conventional technical approaches, represents themost advanced application trend in sludge drying and volume reduction domain, andachieves features such as adjustable water content in the discharged mud(watercontent in the dry mud is below 10%), odorless emission(under the lowtemperature condition, organics in sludges don’t decompose), high degree ofintegration level(double-layer per ton water only covers an area of  1.33㎡), highly optimizedsystem(unattended operation, effectively lowering down labor cost), safety andreliability(no organics being decomposed, no flying dust), high energyefficiency ratio(fully enclosed, no heat loss), high durability(Everycomponents of Biotechina’s low temperature drying machine are given fullyconsideration of corrosion resistance, stability and applicability). Corecomponents of Biotechina’s low temperature drying machine are all adopting theinternationally renowned first-class brands, such as GEA、SIEMENS、Schneider、NORD、SEW, etc., ensuring a higher quality of the equipment.

Biotechina’slow temperature drying technology is a treatment technology for drying sludgesby circulating dry and hot air within the system, and the dry and hot air are generatedby the system itself. This technology, by combining the advantages of both heatpump technology and belt drying technology, has a high processing efficiency,low operating temperature, no such risks as dust or explosion, and no secondarypollution of noise or odor. Investment for this equipment is moderate,perfectly meeting municipal sludges’ drying needs.
