Frequently Asked Questions
Key questions customers usually ask before choosing this solution.
Will the grading process damage the natural bloom (powder) of the blueberries?+
Not at all. We use food-grade soft belts and smooth-surfaced drums specifically designed for blueberries. The entire conveying and grading process is optimized to reduce friction, ensuring the delicate white waxy bloom remains intact, which is a key indicator of blueberry freshness for premium markets.
How does FstSort prevent bruising during high-speed sorting?+
Our blueberry grader features a low-drop height design at every transition point. From the feeding hopper to the collection outlets, the blueberries slide gently rather than falling. Combined with adjustable vibration speeds, this design effectively eliminates internal bruising and maintains fruit firmness.
What are the differences between the Drum Grader and the Belt Grader in terms of performance and price?+
The primary differences lie in capacity, cost and fruit handling. Our drum-type grader (300-500kg/h) is a cost-effective, reliable solution for smaller sorting capacity. In contrast, the belt-type grader (1000kg/h) is a premium solution with a higher capacity, higher price point and it features an ultra-low drop height design. The belt system is significantly gentler, providing the most sophisticated protection for the blueberry's bloom and firmness, making it the best choice for high-end export markets.
Can I customize the grading sizes for different blueberry varieties?+
Yes, the grading holes are fully customizable. Whether you are processing wild blueberries or larger varieties like Duke or Draper, we can provide drums with specific hole diameters (e.g., from 10mm to 20mm+). You can specify the number of grades and the precise size for each grade to meet your local supermarket standards.
How many drums or belt sections should I choose for my grading line?+
The configuration depends entirely on the number of size grades you require. Each drum or belt segment is responsible for one specific size level. For example, to sort blueberries into 4 size categories, we would configure a 3-drum or 3-belt system. While the machine length and price will increase with more grading levels, this modular setup allows you to customize the equipment precisely to your local market’s grading standards.
