Continuous, gentle-flow salad processing engineered to eliminate cut-edge browning, flush heavy debris, and achieve under 3% residual moisture. From raw leaf intake to packaging-ready crisp greens without mechanical cell rupture.
High-Throughput Produce Automation
For commercial pre-cut salad packhouses, airline catering kitchens, and institutional food service providers, maximizing marketable shelf life while controlling microbial risk is a non-negotiable operational priority. Traditional batch dunk tanks and labor-heavy centrifugal basket spinners create uneven moisture retention, excessive handling damage, and product decay.
The Fuma Automated Fresh-Cut Salad Processing Line establishes a synchronized, continuous workflow designed specifically for tender leafy crops—including iceberg, romaine hearts, baby spinach, arugula, and butter lettuce. Engineered to comply with sanitation standards in the U.S. FDA Guidance for Fresh-Cut Produce, the line integrates surgical-precision slicing, dual-basin vortex submersion washing, high-frequency vibratory drainage, and continuous helical spin drying into a unified, hygienic process.
Manual handling bottlenecks, product bruising, and uncontrolled free water directly undermine retail packaging visual appeal and commercial profitability.
Dull blade impact or aggressive mechanical tumbling breaks leaf plant cells, triggering rapid polyphenol oxidase (PPO) release that causes pink cut margins and decay within 48 to 72 hours.
Fine field sand, soil agglomerates, and field insects adhere to crinkled foliage like frisée and spinach, escaping simple bubble agitators and prompting customer chargebacks.
Batch basket spinners depend on operator judgment, creating erratic wet pockets in bags that breed anaerobic bacteria, cause soggy rotting, and cloud retail pillow packs.
A synchronized, automated line footprint that eliminates intermediate manual transfers, lowers labor requirements, and safeguards hygienic integrity.
Dried leaves feed onto an inclined food-grade cleated elevator for immediate delivery to multi-head combination weighers, pillow-bag vertical form-fill-seal (VFFS) systems, or modified atmosphere packaging (MAP) clamshell tray sealers.
All processing units are modularly configured to align with facility footprint, layout geometry, utility connections, and target batch volumes.
* Electrical specs: 380V/50Hz 3-Phase, 220V/60Hz, or 480V/60Hz custom industrial power configurations. Fully CE certified.
Constructed according to EHEDG sanitary design guidelines. Open tubular frames eliminate hollow crevices, while all contact welds are seamlessly ground and acid-passivated to prevent biofilm buildup.
Heavy-duty dual-layer wedge wire filtration captures floating debris and suspends grit before water recirculates through primary hydro-jets, cutting clean water consumption by up to 65%.
Centralized IP65 touchscreen console stores distinct processing recipes (e.g., romaine, baby arugula, shredded cabbage). Automatically adjusts water jet pressure, belt travel, and centrifuge RPM with one touch.
Quick-release belt tensioners, hinged tank inspection lids, and large bottom drainage valves facilitate comprehensive daily CIP sanitization within 40 minutes, minimizing changeover downtime.
From tender organic micro-greens to dense shredded brassicas, Fuma processing lines maintain produce integrity across varied commercial varieties.
Baby spinach, wild rocket/arugula, corn salad, baby butterhead, red mustard, and watercress.
Crisphead iceberg, romaine hearts, lollorosso, escarole, radicchio, and Chinese cabbage.
Green and red cabbage shreds, savoy leaves, and root matchsticks (carrots and daikon).
Coriander, flat-leaf parsley, basil leaves, chives, mint tips, and fresh dill sprigs.

Detailed operational answers for plant managers, sanitation superintendents, and operations directors.
Cut-edge pinking is triggered by cellular crushing under dull or slow blades, which exposes phenolic compounds to air. Fuma incorporates ultra-sharp, high-velocity curved slicing knives that execute clean shear cuts across fibers without pinching cellular membranes. Cut produce immediately drops into a chilling vortex water channel that washes away released cellular juices, effectively halting oxidation before browning starts.
Manual batch spin dryers demand multiple dedicated operators to continually load, balance, spin, and manually dump plastic baskets—an intensive labor bottleneck that causes substantial impact bruising. Fuma continuous centrifugal dryers utilize an inclined, rotating perforated drum with internal helical flights: leafy greens enter non-stop, expand smoothly over the cylinder surface under low-friction centrifugal force, and discharge continuously. This slashes labor requirements by up to 70% while guaranteeing uniform residual moisture below 3%.
Separation relies on fluid density dynamics inside the two-stage vortex washer. Heavy mineral sand and soil settle downward through quiescent perforated plates into tranquilized bottom collection funnels where turbulence cannot pull them back into the main stream. Simultaneously, light floating foreign matter (small insects, floating weed fragments, seed hulls) is channeled toward a motorized rotary wedge-wire drum that continually scoops them into an external waste trough.
Yes. All contact surfaces are manufactured from premium AISI 304 stainless steel (with optional AISI 316L for elevated halide concentrations). The wash tanks are engineered with specialized dosing ports, sanitary sensor wells for pH/ORP monitoring, and ozone diffuser connections, ensuring stable sanitizer parts-per-million (PPM) concentrations in full compliance with international HACCP and GlobalGAP criteria.
The centrifugal dryer outfeed aligns with sanitary inclined cleated Z-conveyors, delivering a steady salad stream to multi-head combination weighers, pillow-bag VFFS units, or MAP tray-sealing lines. The line's central PLC includes digital interlocking signals: if the packaging line pauses or an error occurs, the upstream line gently regulates infeed speed or pauses wash flow without product stagnation.
Whether planning a compact 600 kg/h salad line or a fully integrated 3,000 kg/h automated commissary plant, Fuma engineers provide comprehensive machinery configurations, water reclamation layouts, and packaging synchronization.
