The L-8i is a spray dryer used for research and development. The main body is made of stainless steel, which is excellent for sanitation, and it purifies the drying air with a two-stage air filter to prevent contamination in high-purity products. The enlarged manhole allows for easy internal cleaning operations. The duct from the drying chamber to the cyclone is short, and it connects with a convenient helical clamp, making disassembly easy! *Various options are also available.* 【Features】 ■ Contamination-free ■ Compact and easy to operate and move (with casters) ■ Improved cleanability ■ Two types of product recovery methods ■ Safe and high-performance atomizer ● For more details, please contact us or download the catalog to view.

It is the smallest spray dryer in our equipment lineup. Of course, it can dry raw materials with regular solvents using water, and it can also safely dry raw materials that are difficult to dissolve in water but soluble in organic solvents.

This device has been developed for granulation of fine ceramics, new metals, and inorganic chemicals. Compared to our conventional open-type L and OC models, it is approximately 80% more compact in ground area and about 50% more compact in installation height. Additionally, it comes standard with high-performance hot air filters and bag filters, and is now available at a more affordable price. For more details, please contact us or download the catalog to view.

Spray drying/cooling is possible in an inert atmosphere. Instead of the normally used air atmosphere, nitrogen gas is circulated for spray drying (or cooling) in an inert atmosphere. Not only can the product be processed, but solvent recovery is also possible. For more details, please contact us or download and view the catalog.

In this seminar, you can experience the entire process from the basics of spray drying to actual spraying operations and cleaning. If you want to learn about spray dryers, are interested in trying them but have concerns, or are a new staff member who doesn't fully understand how to use them, please take advantage of this opportunity, which can also serve as training for new employees. ■ Seminar Overview Using the L-8i as the basic model, you will learn about the mechanisms and applications of spray dryers, acquire basic operational skills, and then experience the entire process from starting up the equipment to cleaning, allowing you to gain a deeper understanding of spray dryers.

This device is equipped with a fluidized bed granulator with a stirring mechanism built into the bottom of the spray dryer drying chamber, and further combines a fluidized bed drying and cooling device for finishing drying and cooling of the product, allowing for the continuous granulation (pellet) of products directly from liquid raw materials. ● For more details, please contact us or download and view the catalog.

The spray pyrolysis device that utilizes radiant heat for drying by creating a high-temperature atmosphere inside the furnace required high energy costs due to its heat source being a heater, making scale-up difficult. The production-type spray pyrolysis device replaced the heat source with gas, adopted a jacket structure around the reaction furnace, and enabled the circulation of hot air, allowing for mass production while reducing energy costs compared to conventional machines.

The spray pyrolysis method involves spraying a metal salt solution into a high-temperature furnace, where it undergoes instantaneous thermal decomposition, reaction, synthesis, or calcination to obtain a powder of metal oxide. For more details, please contact us or download and view the catalog.

The special filter cloth (dry) can be easily attached and detached, allowing for quick variety changes by preparing replacement special filter cloths (dry). Additionally, this special filter cloth can be cleaned using a washing machine, significantly improving its washability. It is ideal for granulation and drying of fine ceramics and similar materials.

This device can be safely used for drying and granulating a wide range of raw liquids, including flammable and toxic solvents, as well as low-boiling point solvents (such as methylene chloride), by cooling the circulating gas to -40°C. For more details, please contact us or download and view the catalog.

The "CPL-2" safely dries not only water-soluble raw materials but also highly flammable raw materials that are difficult to dissolve in water and are dissolved in organic solvents, by circulating nitrogen gas in a sealed environment. It can be used with just a power connection and is easy to move with its casters. It is ideal for use in laboratories and development rooms. 【Features】 ■ Compact design for tabletop use ■ All lines from the drying chamber to product recovery are made of stainless steel (SUS304) ■ Each component is lightweight, making installation and disassembly easy ■ Equipped with a touch panel that allows for easy monitoring of the device's status ■ Open operation with only the drying unit is also possible *For more details, please refer to the catalog. Feel free to contact us with any inquiries.
