Drying, filtration, and washing are production steps that are normally handled by multiple machines. The DNFD Delta Nutsche Filter Dryer surpasses this traditional concept by combining operations and offering a more consolidated and flexible approach to the chemical process.
The DNFD Delta Nutsche Filter Dryer is a batch machine that can perform multiple operations:
The intrinsic flexibility and versatility of the DNFD Delta Nutsche Filter Dryer offers several advantages:
The DNDF Delta Nutsche Filter Dryer was developed as a result of Delta’s more than 50 years’ experience. Direct knowledge of the production process has allowed Delta to make constant progress in the component design:
Delta has developed standard DNFD machine configurations to adhere to the specific production needs for several applications and industries:
In addition, Delta offers a wide production range for the Delta Nutsche Filter Dryer:
As per the Delta Costruzioni Meccaniche philosophy, each machine can be completely customized to the customer’s needs. The following list of DNFD Delta Nutsche Filter Dryer options is only a fraction of the solutions that Delta has developed over the years:
Developments for the DNFD Delta Nutsche Filter Dryer are ongoing. Using its experience and taking into consideration main process needs, Delta designed solutions to improve known process performance issues:
The goal of this device, which further improves the flexible features of the DNFD, is to have the ability to use one machine for:
The Tilting system is based on a mechanism that allows machine body rotation. In the case of partial rotation (15-30°), the system improves machine discharge performance, helping the product move to the discharge nozzle. In the case of total rotation, the machine also becomes (in a tilted position) a reactor, combining reaction, crystallization, filtration, and drying.
Delta Ultra Dry for DNFD
The Delta Ultra Dry is a custom filtering sheet design that allows the blowing of nitrogen from the lower side. The system can have different applications depending on what operation the DNFD Delta Nutsche Filter Dryer is performing:
Delta side withdrawal system (EU patent EP 3 322 498 B1)
The Delta side withdrawal system improves filtration performance, by incorporating the sedimentation behavior of some products (decanting). Some side nozzles allow liquid withdrawal, decreasing filtration time and improving product quality.
