Vacuum Roll to Roll Drying System
Suitable for drying cathode/anode elecrodes
Features for Vacuum Roll to Roll (RtoR) drying system
- Energy Saving
By adopting a continuous process, our product eliminates the need for cooling down at each stage of a batch process. This significantly minimizes energy loss, leading to considerable energy savings and the development of more environmentally friendly processes. - Uniform Heating
RtoR drying is a continuous process where the electrode material is coated onto a flexible substrate in a continuous web format. Compared to conventional roll drying, RtoR processing provides uniform product quality. - Reduced Drying Time
RtoR drying is designed for high-throughput production, making it suitable for large-scale manufacturing. It allows for the efficient processing of electrode materials in large volumes. Compared to conventional roll drying, RtoR processing significantly reduces processing time. (12hr→0.6hr). - Cost Efficiency
RtoR processes are cost-efficient for large-scale production due to minimal downtime and reduced manual intervention. They are highly automated, streamlining production. - Space Saving
The vertical arrangement of the heaters reduce the installation space to 1/10 compared to the horizontal arrangement. - Lead time reduction
By adopting a gate valve mechanism, the lead time for product replacement is greatly reduced.
Conventional roll drying in batch process compared with Vacuum Roll to Roll drying system
Batch vacuum drying system requires a lot of factory space compared with RtoR system.
Differences between batch vacuum heating systems
- Heat treatment
The biggest difference between the batch type roll drying process and our RtoR drying system is how we can treat uniform heating to the electrodes. Companies that manufacture electrodes where they have drying process in the production line, they usually face a problem called “Springback Effect”. This is caused when there are temperature differences between the inner part and the outer part of the electrode roll, which then causes the cathode/anode materials to “Spring back” even though they are pressed in the previous processes. - Energy Saving
Since the conventional vacuum heating systems uses nitrogen (N2) to make a “vacuum” atmosphere, the operational cost is significantly high. Also, the structure of the RtoR drying system has a significantly smaller chamber than the conventional systems, power consumption is also dramatically lower. It is estimated have approx. 50% lower power consumption and 100% less nitrogen (not necessary) compared to convetional systems which also has a large impact to CO2 emission!
