Gridbots powderSORT is a world-class powder inspection system and AI driven API powder inspection system engineered for pharmaceutical, nutraceutical and food powder manufacturers. Built as a fully integrated powder sorter, it inspects bulk powder for variations in colour, shape, size and impurities above 50 microns — automatically removing them before the material reaches packaging.
The system uses multiple high-speed line-scan cameras mounted in a precision-engineered inspection tunnel together with NVIDIA GPU-based controllers running deep-learning algorithms. The powder sorter identifies hair, insects, black particles, plastic flecks, magnetic contamination and shade variations in real time, and ejects them via high-velocity vacuum nozzles into a separate impurity bin.
Built from Food Grade SS316L with GMP and CFR21 compliance, an inbuilt magnetic sieve, vibratory hopper and automatic clean-in-place purging mechanism, the Gridbots API powder inspection system handles powders from 50 to 2000 microns at output capacity ranging from 100 kg/hour up to 5 tonnes per hour — delivering true Industry 4.0 powder quality control with no moving parts in the inspection chamber.

Pharma Grade Build
The Gridbots powder inspection system is trained on a dataset of over 1.5 million annotated impurity images across pharma APIs, sugar, salt, spices, milk powder, protein powders and chemical powders. Below is a visual catalogue of contaminants that our API powder inspection system detects, classifies and ejects in real time.
Human or animal hair fibres — critical contamination in pharma & food powder.
Whole or part insect bodies — reportable defect in API and food powder.
Carbon, charred material or burnt residue contaminating the powder batch.
Iron, steel or ferrous shavings — removed by inbuilt magnetic grill.
Coloured plastic fragments from packaging or processing equipment.
Translucent glass fragments — critical safety hazard in pharma powder.
Mineral grit or stone particles from raw material or environment.
Off-shade granules indicating moisture, oxidation or contamination.
Lumped or oversized agglomerates outside specification range.
Charred or scorched particles from process overheating.
Plant matter, husk fragments or stem pieces in spice and food powders.
Caked agglomerates from moisture absorption during storage or handling.
GMP compliant Food Grade SS316L body with IP65 ingress protection on camera and controller units. Designed for pharma and food clean rooms.
1000 kg capacity hopper with vacuum auto-feed, level sensor based start-stop control, and inbuilt magnetic grill to remove ferromagnetic contaminants upfront.
Multiple high-speed line-scan cameras with aberration-free lenses inspect every particle. AI classifies impurities including hair, insects, black flecks and shade variations.
Multiple high-speed suction nozzles eject impurities precisely into a separate bin without disturbing surrounding clean powder. Self-contained vacuum unit included.
Three-channel output system with bins or bags for sorted clean API/food powder, impurities and oversize material — ready for direct packaging integration.
Variable output from 100 kg/hour to 5 tonnes/hour depending on particle size and density — scalable to plant requirements.
The Gridbots API powder inspection system ships with a built-in IIoT analytics dashboard. QA managers, plant heads and shift supervisors get live visibility into impurity rates, yield, throughput and batch-wise contamination trends — turning raw camera data into actionable factory-floor intelligence and audit-ready CFR21 reports.
