Frequently Asked Questions
Clear answers regarding equipment customization, international shipping, electrical certifications, and overseas commissioning.
Our engineering team starts from your raw material properties (variety, dirt percentage, initial temperature), required hourly input, target cut sizes or dryness, and workshop layout. We provide 2D CAD floor plans, 3D equipment models, and mass balance diagrams to ensure optimal workflow and utility connections.
We provide a 12-month complete mechanical warranty following commissioning. In case of any component defect, free replacement parts are shipped via DHL/FedEx priority air freight within 72 hours. We offer 7×24 online remote video support and can dispatch commissioning engineers to your factory site worldwide.
All parts in contact with food and process water are constructed strictly from certified food-grade SUS304 or SUS316 stainless steel. Conveyor belts are FDA-approved sanitary PU or modular food-grade POM, meeting European CE and North American sanitary food standards.
We accept T/T (30% deposit, 70% before shipment after video FAT inspection) and Irrevocable Confirmed Letter of Credit (L/C at sight). Stand-alone machines typically ship within 15–25 business days; complete turnkey production lines require 35–55 business days.
Yes, absolutely. We encourage clients to courier sample fruits, vegetables, or tubers to our Zhengzhou testing facility. Our technicians will conduct actual washing, abrasive/pneumatic peeling, precision dicing, or freeze-drying trials, providing multi-angle 4K video documentation and lab yield data before contract finalization.
All equipment is thoroughly cleaned, coated with anti-corrosion protective film, wrapped in moisture-barrier heat-shrink foil, and anchored into heavy-duty fumigation-free plywood export crates or strapped directly into 20GP/40HQ/40FR containers using steel cables and chocks.
