Cashew nut processing plant

A professional-grade plant must integrate several key stages: Cleaning and Grading (to sort raw nuts by size), Steam Cooking (to loosen the shell), Shelling (automatic or semi-automatic), Drying/Baking (to peel the inner skin), Peeling, and Color Sorting. High-efficiency lines should feature stainless steel 304/316 construction for food contact parts to ensure hygiene and durability.

Buyers must match the plant capacity (typically ranging from 100kg/h to 2000kg/h) with their raw material supply. Fully automatic lines reduce labor costs but require higher technical maintenance, while semi-automatic lines offer flexibility for regions with lower labor costs. Ensure the broken rate of kernels is kept below 5-10% to maximize the market value of the final product.

The machinery must adhere to CE certification for electrical safety and ISO 9001 for manufacturing quality management. Since it involves food processing, the equipment design should facilitate HACCP (Hazard Analysis and Critical Control Points) compliance, featuring easy-to-clean surfaces and food-grade lubricants to prevent contamination.

Industrial cashew plants usually require 3-phase industrial electricity (380V/50Hz or 440V/60Hz). Additionally, the Steam Cooking unit requires a stable boiler or steam generator, and the Pneumatic Peeling machines require a high-capacity Air Compressor. Always verify the total kilowatt (kW) load to ensure your facility's power grid can support simultaneous operation.

Always mandate a Pre-Shipment Inspection (PSI) conducted by third-party agencies like SGS or Bureau Veritas. Request a Live Video Factory Audit and a Running Test using actual cashew samples before final payment. For secure transactions, utilize Made-in-China.com's Secured Trading services to ensure funds are only released upon proof of shipment.

Focus on the Total Cost of Ownership (TCO) rather than just the sticker price. Negotiate for extended warranties (24 months instead of 12), a wear-parts package (blades, belts, and gaskets for 2 years), and on-site installation/training services. Ask for a discount on the MOQ if you are planning a multi-phase expansion.

Cashew plants involve bulky and heavy components; ensure the supplier uses Seaworthy Vacuum Packaging and Steel Crate Reinforcement to prevent rust and mechanical damage during sea transit. Clearly define Incoterms (FOB or CIF) and ensure the Bill of Lading accurately reflects the machinery's HS Code to avoid customs delays.

Prioritize suppliers who provide Remote Technical Support via AR/Video and have a documented 24-hour response policy. Confirm if the supplier provides English-language Operation Manuals and PLC software backups. For large-scale plants, negotiate for the supplier to send engineers for on-site commissioning and staff training.
