Spice and seasoning processing — machinery overview
Spice and herb processing machinery handles the preparation of raw dried spices and herbs into finished ground, crushed, or whole-spice consumer and food service products. A typical spice processing line includes: incoming raw material inspection and cleaning (removing stones, stems, and foreign material using air classifiers, destoners, and vibrating screens); drying (reducing moisture to the target level for safe grinding and storage — typically below 10–12% moisture); size reduction (primary and secondary grinding using hammer mills, pin mills, disc mills, and impact pulverisers to achieve the target particle size); sifting and classification (removing oversize particles); blending (for seasoning and spice blend production — ribbon blenders, paddle blenders, and rotary drum blenders); filling and packing (sachets, jars, pouches). Spice grinding generates fine, combustible organic dust — dust explosion risk management (ATEX compliance, dust extraction, earthing, controlled spark generation environments) is a serious safety requirement that must be built into the plant design from the outset.
Frequently asked questions
What particle size specifications are typical for commercial ground spices?
Ground spice particle size is typically specified in mesh size (US mesh or BS sieve equivalent) or in microns (µm) using laser diffraction. Common commercial specifications include: fine ground (for consumer sachets and food ingredient use) — 40–80 mesh (177–420 µm); standard ground (general consumer pack) — 20–40 mesh (420–840 µm); coarse crushed or cracked — 5–20 mesh (840 µm to 4mm). The exact specification depends on the spice type, the end application, and the buyer's or retailer's specification. Request that the grinding machine supplier provide test data from grinding trials on your specific spice or herb to verify the achievable particle size distribution before purchase.
