Condition: used, Year of construction: 1996, functionality: fully functional, overall weight: 1,750 kg, total width: 1,120 mm, total length: 3,750 mm, number of chambers: 1, Equipment: documentation/manual, For sale: a high-performance fluid bed dryer from the renowned manufacturer Buhler, model OTWG-280. This is a horizontally constructed machine designed for the continuous thermal processing of bulk and granular materials. With its sectional design, the machine can function both as a dryer and a cooler, making it an extremely versatile element of any production line. The machine utilizes the principle of fluidization. The process involves blowing hot (or cold) air through a perforated base holding the raw material. The air lifts the material particles, forming a so-called "fluidized bed." In this state, each particle is surrounded on all sides by the heating/cooling medium, providing: - Instant heat exchange (significantly faster than drum dryers) - Uniform drying with no risk of localized overheating - Gentle product handling – minimal risk of mechanical damage to raw materials Nodpfsy D Iiujx Aqvolb We have two OTWG 280 units and one OTWG 90 unit available. The price for the OTWG 280 is listed in the advertisement. OTWG 90 price: 40,000 EUR.
