The Drum Flaker (Chill Rolls) is a simple and reliable machine that cools and solidifies into flakes liquid neat soap, soap/syndet (“combo”), and syndet products. It has two special, counter-rotating stainless steel rolls equipped with an internal cooling jacket. Cold water is conveyed through a spiral pattern all around the inner surface of the drum to grant uniform heat transmission.
The drums are equipped with rotary joints for proper water distribution and consistent water recycling in a closed circuit when using a water chiller.
Separate motor-reducers drive each drum and the product discharge conveyor. These independent drives allow easy maintenance and flexibility of operation. Liquid soap or syndet slurry is pumped on the rolls that spread it evenly among them, in a 0,3 — 0,5 mm thick layer that is quickly cooled down and solidified. The product is then scraped off the rolls by the doctor blades in the form of flakes and falls onto a discharge conveyor belt.
The Drum Flaker is suitable to produce soap flakes at a temperature of 38-40°C approximately, starting from liquid soap at 80-90°C.
The soap produced throughout this process has no dry specs because of the very limited drying involved.
