Incoming dried spices and herbs typically contain foreign material including: stones and heavy dense material (sand, gravel, dried mud clumps); light material (stems, straw, husks, dust); and metal fragments. Cleaning equipment to remove these contaminants before grinding includes: vibrating flat screens (remove oversize material — large stems, straw, and other items that sit on top of the screen; and undersize fine material — dust, sand — that falls through; the spice is retained in the middle fractions); air classifiers and aspiration systems (a controlled air stream separates light material — empty seeds, dust, light stems — from heavier, denser spice material); destoners (separate dense, heavy material — small stones, glass fragments, dense seeds — from the spice material using a combination of air and vibration; stones and dense material report to one discharge and the cleaned spice to another); magnetic separators and metal detectors (remove ferromagnetic fragments — essential before grinding, as metal fragments cause severe damage to grinder screens and blades); and optical colour sorters (remove discoloured, mouldy, and off-colour spice material — see separate colour sorter page).
Frequently asked questions
Why is stone removal especially important before spice grinding?
Stone and grit removal from spices before grinding is critical for two reasons: first, stones cause immediate and severe damage to grinding machine screens, hammer tips, and blades — a single small stone passing through a hammer mill or pin mill can destroy a screen and halt production for hours; second, stone fragments that pass through a grinder (if the screen is damaged by the stone) contaminate the spice powder with dense mineral particles that are a food safety hazard. Installing a destoner upstream of the grinder is standard practice in any commercial spice grinding operation. The destoner should be checked and cleaned regularly as the reject discharge can become full and the machine can become ineffective if not maintained.
What foreign material screening is required before spice powder is sold to food industry buyers?
Food industry buyers of spice powder typically specify foreign matter content limits: maximum stone/extraneous vegetable matter (EVM) content by weight; maximum sand and silica content (measured by acid-insoluble ash); metal contamination limits (typically set by metal detection sensitivity rather than by chemical analysis); and absence of certain foreign materials by visual inspection. Incoming cleaning and processing equipment must demonstrate capability to produce spice powder meeting these specifications consistently. Retain records of cleaning equipment operation and maintenance as evidence of due diligence for food safety audits. For export markets, the buyer's specification and the relevant food safety standard (BRC, IFS, or SQF) determine the required level of foreign matter control.
