China Multicoil Dryer - High-Quality Suppliers & Factory for Efficient Heating and Cooling Solutions
Principle
The Multicoil unit consists of a rotor which forms the indirect contact heating/cooling surface, and a stationary shell or vessel. The rotor consists of a number of parallel coil sets arranged along a central shaft. Each coil set contains a number of concentric tubes. The heat transfer medium may be steam or liquid.
The design of the customized system
Each application of the Multicoil system requires careful investigation of the processing characteristics of the actual product. On this basis, operating conditions and system design are selected. The scope of supply includes complete processing systems or just the Multicoil.
Application Industry
Advantage
The energy consumption of the Multicoil processing system is low compared to systems based on convective heat transfer.
The Multicoil utilizes indirect energy transfer by means (steam, water, thermal fluids). Therefore, the process requires a low flow of air or inert gas only.
Due to the compact design of the Multicoil and the exhaust system, installation costs are low.
Small exhaust gas quantities result in small exhaust gas cleaning systems. As a consequence of the low gas velocities inside the shell, only small fractions of solids are entrained.
Due to the low air/inert gas flow through the Multicoil unit, a significant part of the vapour in the exhaust gases is condensable, thus providing efficient energy and solvent recovery.
Frequently Asked Questions
The Multicoil unit features a rotor with parallel coil sets of concentric tubes along a central shaft. The heat transfer medium (steam or liquid) flows through these tubes, transferring heat indirectly to the product within the stationary shell without direct contact.
Yes. Each system design and its operating conditions are custom-tailored based on a thorough investigation of the processing characteristics of the specific product being handled.
Unlike convective heat transfer systems, the Multicoil system utilizes highly efficient indirect heat transfer, which naturally consumes less energy during operation.
Because the system operates with indirect energy transfer, it requires very little air or inert gas flow. The low gas velocity inside the shell minimizes solid particle entrainment, allowing for smaller, less expensive exhaust gas cleaning systems.
It is highly effective across diverse sectors including the chemical, petrochemical, mining, wood processing, brewing/distilling, food, and pharmaceutical industries.
