The central Russian black soil area is a world-famous fertile soil belt, producing high-sugar beets and crisp radishes. B***E Agricultural Group is the largest root vegetable supplier in Moscow, supplying Russia's top three supermarket chains and many food processing plants. However, Russia's unique extreme cold climate and soil conditions bring huge challenges to root vegetable cleaning:

Hard-to-remove Frozen Mud: Root vegetables harvested from frozen soil are covered with 2-3cm thick sticky frozen mud, which cannot be melted by normal-temperature cleaning, and manual knocking seriously damages the skin.

High Skin Damage Rate: Delicate skin of beets and taro is easily damaged by uneven force of traditional brush washers, with damage rate up to 18% and high supermarket return rate.

Sediment Residue in Roots: Carrots and parsnips have many root gaps with hidden sediment, low manual picking efficiency. A batch of carrots was once rejected by the EU due to sediment residue.

Winter Freezing Shutdown: Winter temperature drops to -30℃, traditional washing line water circulation system freezes overnight, almost unable to operate from November to March.

Solution: Finding a Cleaning System for Extreme Cold + Sticky Frozen Mud

The client's requirements were clear: normal operation at -30℃, complete removal of frozen mud without skin damage, and meeting EU export standards.

After comparing equipment from Germany and the Netherlands, the client chose our company. Our advantage lies in deep process adaptation for extreme cold environments and frozen mud, not general-purpose machines.

Solution: 4 Customized Designs for Extreme Cold Root Vegetables

1. Hot Water Pre-soaking + Ultrasonic Mud Melting System, 100% Frozen Mud Removal

Constant 45℃ hot water pre-soaking section with ultrasonic cavitation softens and removes frozen mud within 30 seconds without mechanical knocking. Test shows 100% mud removal and 0 skin damage for beets.

2. Multi-stage Flexible Brush Washing, Damage Rate Reduced to 1.5%

5-stage brush roller cage: hard brushes for large mud clods, soft brushes for fine cleaning, polishing brushes for smooth surface. Independent speed adjustment for delicate varieties, damage rate down from 18% to 1.5%.

3. 360° High-pressure Spraying + Special Root Nozzles

8kg/cm2 360° surround spraying with special fan nozzles thoroughly flushes sediment in root gaps. Clean roots pass EU visual inspection system.

4. Fully Enclosed Anti-freeze Circulation System, Normal Operation at -30℃

Heating cable + polyurethane insulation, built-in circulating heating for water tank and pipelines, constant water temperature 15-20℃. 24-hour continuous operation even at -30℃, solving winter shutdown problem completely.
