Product Overview – Two Independent Solutions for Chestnut Processing
Fstsort offers two separate pieces of equipment for chestnut processing. You can purchase them individually or combine them into a complete line.
Product | Function | Best for |
|---|---|---|
Chestnut Washing Line | Cleaning + manual sorting | Customers who only need washing and defect removal |
Drum Screen Grader | Automatic size sorting by diameter | Customers who need graded chestnuts by size |
💡 Combine them: Washing Line → Drum Screen Grader = Complete washing + grading line.
Product 1 – Chestnut Washing Line
Description
This Fstsort chestnut washing line is designed for nuts like chestnuts and macadamia. It consists of:
Bubble washing tank – with backward spray and debris filter
Water sprinkles & brushes – deep cleaning
Air blowers – removes surface moisture
Roller inspection table – for manual sorting of defective nuts
✅ No automatic grading – this line is for washing and manual sorting only.
Key Features
High efficiency
Gentle on nuts – reduces cracking
Variable speed
Customizable capacity
CE certified
Bubble Washing Tank – Detailed Design
Our bubble washing tank is specifically designed for chestnuts, which often come with dirt, leaves, and other debris.
How it works:
Feature | Description |
|---|---|
Bubble generator | Creates turbulent water to loosen dirt and debris from chestnut surfaces |
Backward spray nozzles | Spray water backward, pushing chestnuts forward toward the elevator – no mechanical pusher needed |
Filter screen | Separates debris (leaves, stems, mud) from the water; debris is directed to a small side tank for easy removal |
Water circulation | Efficient water use – debris is filtered out before water is recirculated |
✅ Benefits: Continuous operation, less manual cleaning, better water efficiency.
Roller Inspection Table
Stainless steel rollers rotate slowly
Workers manually pick out defective or damaged chestnuts
Gentle handling – rollers reduce hand fatigue

Product 2 – Drum Screen Grader (Chestnut Size Sorter)
Description
The Fstsort drum screen grader is specifically designed for size sorting chestnuts by diameter. Unlike roller graders (which are not suitable for chestnuts), the drum screen grader uses round holes and gentle tumbling action – the preferred method for chestnut packers worldwide.
How It Works
Chestnuts enter the rotating drum
As the drum turns, chestnuts fall through round holes of increasing sizes
Each size falls into a separate outlet
Gentle tumbling – no cracking or jamming
Key Features
Round holes – match the natural shape of chestnuts
Gentle tumbling – no crushing or jamming
Consistent sizing – accurate diameter separation
High capacity – up to 5–10 t/h
Low maintenance – simple design, easy to clean
Adjustable grades – change drum screens for different size ranges
Specification – Drum Screen Grader
All parameters are customizable.
Parameter | Reference Range | Customizable |
|---|---|---|
Capacity | 3–8 t/h | ✅ Yes |
Number of grades | 3–6 | ✅ Yes |
Hole sizes | Customizable by diameter | ✅ Yes |
Material | Stainless steel (food contact) | ✅ Yes |
Voltage | 380V | 220V, 415V, 60Hz available |
Common Grade Sizes for Chestnuts (Example)
Grade | Diameter Range | Typical Use |
|---|---|---|
Small | < 20 mm | Processing, peeling |
Medium | 20–25 mm | Retail, fresh market |
Large | 25–30 mm | Premium retail |
Extra Large | 30-35mm | Specialty, export |

Frequently Asked Questions
Key questions customers usually ask before choosing this solution.
What is the difference between the washing line and the drum screen grader?+
Washing line – cleans chestnuts and provides a roller inspection table for manual sorting. No automatic grading. Drum screen grader – automatic size sorting machine. Use it alone or after the washing line.
How does the bubble washing tank remove debris from chestnuts?+
The tank generates bubbles to loosen dirt, while backward spray nozzles push chestnuts forward toward the elevator. A filter screen separates debris (leaves, stems, mud) from the water and directs it to a small side tank for easy removal. This design ensures continuous operation with less manual cleaning.
How many grades can the drum screen grader have?+
We offer 3 to 6 grades as standard. A 5-grade configuration is very common for chestnuts, for example: Grade 1: < 20 mm Grade 2: 20–25 mm Grade 3: 25–30 mm Grade 4: 30–35 mm Grade 5: > 35 mm You can customize the diameter range for each grade to match your market requirements.
Do you offer a hot air dryer for complete drying?+
Yes. We can add a hot air dryer after the air blowers if you need chestnuts completely dry for bagging or long-term storage.
