This Dinnissen rotating sieve mixer and blender — sometimes referred to as a rotary sieve or drum sieve — is a compact industrial machine designed for the simultaneous mixing, blending, and size-classification of bulk materials. Dinnissen is a well-established Dutch manufacturer of processing and handling equipment, serving industries such as food, feed, chemicals, and pharmaceuticals with a range of mixing, conveying, and sieving solutions.
The machine is offered used and is located in Barneveld, Netherlands. The type plate is missing, so the exact model designation is unknown; all specifications below are taken from direct inspection of the unit. Construction is dual-material: the housing and screw are mild steel, while the rotating sieves themselves are stainless steel 1.4301 (AISI 304), providing a hygienic contact surface for the product stream. Three interchangeable sieve panels are included, with perforation sizes of 2.5 mm, 3 mm, and 4 mm, allowing the operator to select the appropriate cut point for the application.
The rotating sieve drum measures ø 300 × 800 mm and runs at 81 rpm, driven by a 3 kW motor rated at 400 V and 1,414 rpm. Notably, the motor carries an Ex designation, indicating it is suited for use in potentially explosive atmospheres. The machine is fitted with air-purged glands, which help prevent product ingress at the shaft seals and are consistent with dusty or fine-powder processing environments.
Product enters through a 250 × 250 mm inlet and exits via an 800 × 400 mm outlet. The unit is equipped with a sieve cage assembly and an inspection hatch for routine checks and maintenance access. A switch is included. The overall footprint is 1.70 × 0.75 m, with a total installed height of 0.90 m, making this a relatively compact unit suitable for integration into an existing processing line. The year of manufacture is unknown.
