Low cost Vacuum Rake Dryer environmental friendly

The Rake dryer is a horizontal, batch-type vacuum drying equipment featuring a cylindrical shell with a jacket. Inside the cylinder are a low-speed stirring shaft and rake teeth. After material is fed through the top inlet, steam, hot water, or thermal oil is circulated within the jacket to provide indirect heating. The rake teeth operate in a cycle of forward rotation—stop—reverse rotation, controlled by a time relay, continuously moving the material axially and constantly renewing its surface. Moisture evaporates under heat and is then removed by a vacuum pump. This design ensures high thermal efficiency, enabling the final moisture content of the dried product to be reduced to approximately 0.5%.

This equipment is particularly suitable for processing materials that are prone to oxidation, heat-sensitive, explosive, or containing organic solvents, and is widely used in industries such as chemicals, and food. Operation under vacuum lowers the boiling point of solvents, preventing oxidation and degradation of materials while facilitating recovery of volatile components. Its main drawbacks include relatively long drying times and lower production capacity due to batch operation, as well as a complex structure and higher cost, making it unsuitable for applications requiring frequent changes in product types.

"New beginnings bring renewal." In 2004, as China's drying industry entered an era of increasingly fierce and chaotic competition, "Yixin Drying" was born. Facing a challenging and difficult path ahead, Mr. Li Bayi, the company’s founder and general manager, established from the outset the core philosophy: "Thinking of you at every step." This means thinking more deeply and thoroughly for customers, employees, superiors, and subordinates alike—ensuring that everyone considers others' needs with greater care and attention. Under this guiding principle, the entire company maintains a rigorous work ethic and a spirit of continuous improvement, driving constant innovation in products and technology. Over the past decade, "Yixin Drying" has steadily grown and advanced, earning a stable customer base across chemical, environmental protection, mining, battery, and other industries. Its products have received widespread acclaim and built a solid reputation for quality and reliability.

With China's rapid economic growth and the gradual improvement of laws and regulations, low environmental standards and high energy consumption have become bottlenecks restricting the development of the drying industry. To address these challenges, "Yixin Drying" has accelerated innovation by absorbing and integrating advanced technologies in drying, mixing, and granulation equipment. Through collaboration with multiple domestic technical partners, the company has developed a series of high-efficiency, low-energy-consumption drying systems that are user-friendly, feature advanced control systems, and meet environmental standards—meeting diverse process requirements for drying, mixing, and granulation across various industries. To help clients experience the drying process firsthand and evaluate results directly, the company has established a state-of-the-art testing center where customers can conduct trials with their own materials.

With continued support and encouragement from clients across all sectors, the "Yixin team" is committed to consistently delivering outstanding industry products characterized by excellent design, advanced technology, and superior craftsmanship to serve its valued customers.
