Product Q&A

Q: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.

Q: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.,from10mmto20mm+). You can specify the number of grades and the precise size for each grade to meet your local supermarket standards.

Q:Are the drums and belts replaceable for maintenance or different sorting needs?

Yes. Our blueberry grader features a modular, easy-access design. The grading drums and belts are designed to be easily removed and replaced for deep cleaning or to switch to different grading sizes. This ensures the machine remains versatile throughout the harvest season and simplifies long-term maintenance.

Q:How long is the warranty?

All machines come with a one-year warranty from date of installation.

Q:Do you have people for installation and start up for the machine?

Photos, videos and instructions will be sent to the customer to aid installation and operation of the machinery. If the customer requires additional assistance, an engineer can be sent from China.
