The KM-1 is a batch-type root vegetable washing machine produced by STANCOSTROITEL LLC (ООО ПТП "Станкостроитель"), a Russian industrial equipment manufacturer founded in 1989 on the premises of the Yoshkar-Ola Mechanical Plant. With over 30,000 units delivered to bakeries, meat processing plants, canneries, and food service facilities across Russia and the CIS, the company brings deep domain expertise to food-processing machinery.
The KM-1 is designed for washing potatoes, beets, and carrots at vegetable processing enterprises. Its core mechanism is a motorized conical disc rotating at 51 rpm inside a sealed working chamber.
Batches of up to 80 kg are loaded through a top hatch; the vegetables fall onto the disc, travel in a spiral path, and are continuously rinsed by water from a built-in distributor. Short rubber fingers embedded in the chamber walls catch each root vegetable on every revolution, knocking soil and debris free without bruising or breaking the produce—an important advantage when handling fragile crops such as carrots.
When the wash cycle ends, the disc stops, the discharge door (held by a single rotary lever) swings open, and clean vegetables are removed while dirty water drains through a 160 mm stub into the facility's waste line.
Key specifications: throughput 1,000 kg/hr, single-batch load 80 kg, motor up to 4 kW at 380 V, water consumption 1.5–2 m³/hr, overall footprint 1,200 × 1,200 × 1,200 mm, machine weight 310 kg.
