1. Product Overview
LJ Chestnut Brush Roller Washing Machine is a purpose-built industrial cleaning system engineered specifically for fresh chestnuts and hard-shell nuts. Unlike standard vegetable washers that lack the scrubbing power for tough nut shells, this machine combines high-density wear-resistant nylon brush rollers with multi-angle high-pressure water spray nozzles to aggressively yet safely remove stubborn mud, soil, and field debris — including dirt trapped deep in chestnut shell crevices.
The continuous conveyor design feeds chestnuts through multiple brush roller stations, ensuring 360-degree shell coverage and thorough cleaning. Fully fabricated from food-grade SUS304 stainless steel, this machine is the essential first-stage equipment for chestnut processing plants, roasted chestnut factories, and frozen chestnut export facilities worldwide.
2. Core Advantages & Features
Specialized Hard-Shell Cleaning: High-density nylon brush rollers with optimized bristle stiffness provide aggressive scrubbing action to remove mud from chestnut shell crevices — without cracking or damaging the hard shell.
Multi-Stage Brush Design: Multiple brush roller stations (upper and lower) ensure 360-degree coverage, cleaning top, bottom, and sides of each chestnut in one pass.
Integrated High-Pressure Spray: Water spray nozzles positioned above and between brush rollers continuously flush away loosened dirt, preventing re-contamination.
Variable Speed Control: Adjustable conveyor and brush roller speed to match different chestnut sizes, dirt levels, and throughput requirements.
Water Recycling System: Built-in sedimentation tank and filtration system captures soil and debris, reducing water consumption by up to 40%.
Food-Grade SUS304 Construction: Full stainless steel body with smooth weld-free surfaces for easy cleaning and maximum hygiene compliance.
Gentle Product Handling: Despite aggressive brush action on the shell, the machine's design prevents chestnuts from being crushed, scored, or damaged during the cleaning process.

5. Operation & Maintenance Guide
Pre-Start Check: Verify water supply pressure, check brush roller rotation direction, ensure spray nozzles are unobstructed.
Normal Operation: Feed chestnuts evenly via conveyor, adjust speed and water flow as needed. Monitor discharge quality periodically.
Daily Cleaning: After production, flush the brush rollers, sedimentation tank, and conveyor belt with clean water. Remove accumulated debris from the filtration screen.
Weekly Maintenance: Inspect nylon brush bristle wear, clean or replace clogged spray nozzles, lubricate transmission bearings and chains.
Monthly Check: Verify motor and pump performance, inspect electrical connections, check belt tension, tighten all bolts and fasteners.
6. FAQ
Q: Will the brush rollers damage or crack the chestnut shells? A: No. Our nylon brush rollers are specifically designed with optimized bristle stiffness — firm enough to remove caked mud from shell crevices, but flexible enough to prevent shell cracking or surface damage.
Q: Can this machine wash other nuts besides chestnuts? A: Yes. The machine is compatible with walnuts, hazelnuts, almonds, macadamia nuts, and other hard-shell nuts. Brush roller speed can be adjusted for different shell hardness levels.
Q: How does the water recycling system work? A: Used water flows into a sedimentation tank where heavy soil particles settle. Filtered water is recirculated back to the spray system, reducing total water consumption by up to 40%.
Q: Can the machine handle very muddy chestnuts from the field? A: Absolutely. This machine is designed for post-harvest field conditions. For extremely muddy chestnuts, we recommend a pre-soaking stage or adjusting the conveyor to a slower speed for longer brush contact time.
