Company Profile

Established in 1991, Jiaozuo ZJN Environmental Protection Equipment Technology Co., Ltd(was named Zhuoyue Drying Equipment Factory) is an innovative enterprise who has been specialized in the technology researching, equipment manufacturing and project engineering of drying high humid and viscous materials.


Take “high-efficiency, energy saving, being practical” as the principle, our company dedicates in environmental protection business. With over 20-years striving and innovation, we have got outstanding achievements in drying technology for sludge, solid waste and slags. We are always in the front of domestic drying technology which is rapidly developing. Based on advanced scientific management, integrity and pragmatic spirit, ZJN has won over 100 items of national patents, as well as being awarded many national honors and titles, such as “Identification of scientific and technological achievements”, “China Top 500 Private Technology Enterprise”, “Integrity Model Company”. We also passed ISO 9001: 2008 Quality certification.


Sticking to the combination of production, study and research, we cooperate with School of Environment & Natural Resources of Renmin University of China, Environmental Protection Research Institute of Beijing Institute of Science and Technology, Henan Polytechnic University and establish ZJN Drying Technology Researching Center, which independently designed, researched & developed, then produced the Rotary Harrow Rolling Triple Stage & Multi-loop Drying Equipment. The usage of this equipment made good economic, social and environmental benefits. It has been widely used in many industries such as Paper Making, Textile, Dying, Printing, Electroplating, Leather, Pharmacy, Chemical, Sewage Treatment, Feed, Liquor, Starch and Biological fermentation.
