A drum dryer is a conduction heating type dryer that introduces a heat medium (usually steam) into the interior of a rotating drum (cylinder), supplies liquid raw materials to the heated drum, and simultaneously performs evaporation and concentration while adhering the material in a thin film to the surface of the drum, allowing for rapid evaporation and drying. As the drum rotates once, the dried material is continuously scraped off the surface of the drum with a fixed knife.

A vacuum drum dryer refers to a type of drum dryer that incorporates the mechanism of a conventional atmospheric drum dryer into a vacuum chamber, enabling continuous operation under reduced pressure conditions.

Katsuragi Industrial's heat recovery drum dryer was developed with the aim of reducing equipment costs and running costs. Normally, the exhaust (evaporated vapor) from a dryer is released into the atmosphere, but this exhaust is recovered through a scrubber condenser and heat recovery unit, and the recovered heat is used for pre-concentration. By implementing this pre-concentration, a smaller drum dryer can be adopted, successfully reducing steam consumption by approximately 40% compared to our previous models.

Conventional sludge dryers generally use conduction heating dryers. However, when drying dewatered sludge or food residues, conduction heating dryers face issues such as the material adhering to the heat transfer surface during the drying process and the material becoming granular or clumpy, making drying difficult. The sludge dryer (D.A.C.) developed by Katsuragi Industries Co., Ltd. has solved all these problems at once.

The double-cone dryer is a batch-operated conductive heat transfer rotary dryer, primarily suitable for vacuum drying of powdery and granular materials. The main body is a jacketed tumbler, where the raw material is loaded to 30-50% of its full capacity and dried while repeatedly stirring and dispersing through rotation.

In the chemical industry, there are many processes for cooling and solidifying substances in a molten state. However, if these are solidified by being placed in molds through batch operations, it cannot handle large-scale processing and presents many difficult issues in rough crushing, grinding, weighing, and bagging operations. The cooling and solidifying device, the drum flaker, addresses this by continuously forming the molten substance into flake form during the cooling and solidification process, resulting in several advantages: 1) It becomes easier to re-dissolve. Additionally, the working environment improves compared to powdered products. 2) Weighing and bagging operations become easier and can be automated.

This is an introduction to the "Coil Concentrator," a type of concentrator that coils pipes and rotates them within a concentration tank while sending steam into the pipes. 【Features】 - Since the rotating coil serves as the heat transfer surface, there are no blockages or scorching caused by concentrated substances inside the pipe. - There is no occurrence of hard scale due to dry running or overheating, allowing for long-term continuous operation. - Concerns about the generation of concentrated substances or decomposition products seen in localized heating, as well as the accumulation of sludge in stagnant liquid areas, are unnecessary. - It has excellent control for high-concentration production equipment during continuous operation, making it suitable for automation, labor-saving, and enabling the production of uniform products. - It demonstrates sufficient and stable performance with only 1/2 to 1/5 of the heat transfer area of conventional concentration devices, making it very compact and requiring no installation space. - It can operate under any pressure, whether in a vacuum or at atmospheric pressure, and can be operated under temperature conditions suitable for the liquid properties, preventing product degradation and discoloration. *For other functions and details, please download the catalog or contact us.*
