Eqraft Eqrader optical onion and potato grading platforms

The Eqrader optical sorting system inspects individual onions and potatoes inside a dark chamber using near infrared NIR spectroscopy. Evaluating internal tissue, skin blemishes, shape and size, the unit separates damaged produce and grades crop into customizable output categories.

Near infrared spectroscopy inside an enclosed dark room identifies internal decay
Multi-angle digital optical sensors measure profile dimensions, geometry and skin
Individual cup conveyor system with dynamic strain-gauge weighing at high speed
Minimized commercial claims through accurate rejection of hollow or rotting tubers

Enclosed Eqraft Onion Topper cutting systems (KS and KR configurations)

Engineered with high-speed rotating blades, the enclosed Onion Topper severs dry foliage and roots from onions and shallots. An aerodynamic propeller profile establishes internal air circulation that strips loose skins and dust without venting debris into surrounding rooms.

Propeller-shaped cutter arms generate closed circulation to remove dry husk debris
Available in modular compact layout KS or walk-in service enclosure design KR
Quick screen replacement system supported by an integrated overhead crane hook
Hardened cutting knives precision balanced to prevent operational vibration wear

Eqraft Onion Shaver finishing root trimming and cleaning units

The Eqraft Onion Shaver delivers precise finishing cuts to root plates on onions and shallots ahead of packaging. Fine-tuned rotary blades trim root fibers flush with the bulb base without puncturing protective succulent scales, preserving natural storage resilience.

Precision finishing cut of root fibers prior to premium supermarket pre-packaging
Gentle produce progression along vibrating trays prevents scuffing outer skin layers
Adjustable cutting height mechanisms tuned for multiple bulb calibers and varieties
Protection against flesh gouging to stop moisture leakage and bacterial contamination

High-speed Eqraft Baxmatic bagging machines for mesh and paper bags

The Baxmatic bagging station automatically positions, fills and transfers open-mouth wicket bags for onions and root crops. Accommodating woven net, jute, paper and polypropylene sacks from 1.5 to 25 kg, this system eliminates spillage and integrates into downstream sewing lanes.

Continuous throughput rated from 400 up to more than 1,000 bags per operational hour
Versatile handling of wicket mesh bags, woven jute, poly and industrial paper sacks
Automated bag mouth opening check prevents product discharge if bag fails to seat
Direct mechanical linkage to multi-head weighers, carton fillers and sewing lanes

Eqraft combination weighers, bin tippers and surge storage logistics

Eqraft multi-head combination scales and bulk handling platforms provide gentle weighing and smooth crop transfer from storage crates into grading lines. Cushioned bucket liners and variable-speed surge belts protect produce from mechanical shock.

Advanced combination weighing algorithm minimizes giveaway while maintaining rate
Heavy-duty hydraulic and electric tippers for standard agricultural storage crates
Surge bunkers equipped with variable-frequency bottom belts for uniform flow pacing
Tool-less quick-disconnect hoppers allow rapid washdown and soil debris removal

Optical internal rot detection and grading in Eqraft Eqrader units

Eqraft Eqrader optical grading platforms deliver a revolutionary approach to sorting onions and potatoes. The foundational engineering feature is individual tuber evaluation inside a specialized dark chamber using near infrared NIR spectroscopy.

The infrared spectrum penetrates external dry skins, detecting internal rot, hollow heart defects and hidden bacterial decay.

Accurate separation of defective bulbs allows growers to meet strict retail supermarket standards and eliminate commercial penalties.

Multi-angle digital cameras capture diameter, geometry, skin defects and color distribution simultaneously, while individual soft cups deposit product gently into designated output discharge lanes.

Engineering principles of closed onion toppers: KS and KR models

Enclosed Eqraft Onion Topper units (KS and KR configurations) carry forward four decades of design heritage originated by ERC in 1984. The machine shears dry foliage and roots via rotating cutter arms positioned above vibrating screens.

Produce moves along the screen through tuned vibration, aligning stems toward the high-speed cutting edges.

Aerodynamic cutter arms establish closed air circulation within the sealed machine body. This airflow pulls foliage toward the blades and strips dry skins without venting dust into facility rooms.

For routine servicing, an integrated swing crane allows rapid screen replacement for multiple crop sizes without requiring heavy external shop cranes.

Precision root plate trimming with Eqraft Onion Shaver systems

Premium onion packaging demands neat root presentation without damage to bulb tissue. The Eqraft Onion Shaver is engineered for delicate root trimming following initial foliage topping.

The rotary cutting head features micrometer adjustments to trim fibrous root tails flush with the base plate without nicking fresh succulent scales.

Preserving base integrity prevents moisture loss and stops gray mold pathogens from invading stored produce. Smooth produce feeding across polymer-damped vibrating trays eliminates abrasive skin scuffing.

High continuous throughput allows seamless integration between cleaning units and downstream automated bagging machinery.

Automated high-speed bagging with Eqraft Baxmatic packaging units

Eqraft Baxmatic bagging stations automate continuous packing of onions and root crops into wicket mesh, woven and paper sacks from 1.5 to 25 kg. The system automates bag pickup from magazines, mouth opening, product drop and transfer to downstream sewing lines.

Heavy-duty mechanical fingers hold bag collars gently throughout filling cycles.

Optical sensors verify complete bag opening prior to product discharge, preventing floor spillage if packaging material fails to feed correctly.

Direct synchronization with multi-head weighers achieves packing speeds exceeding 1,000 bags per operational hour, substantially reducing labor requirements at packaging bottlenecks.

Multi-head combination weighing and produce protection mechanisms

Forming commercial bags to exact weight targets requires eliminating product giveaway. Eqraft combination weighers calculate multi-bucket combinations with single-tuber precision.

The microprocessor algorithm evaluates radial tray loads continuously, choosing the optimal discharge combination within milliseconds to maintain packaging pace.

All internal contact areas, distribution cones and collection buckets feature food-grade polyurethane damping liners that prevent mechanical bruising during drop sequences. Modular bucket assemblies feature quick-release fasteners, enabling rapid washdown and soil debris cleaning without hand tools.

Preventive maintenance schedule and factory nameplate identification

Long-term reliability of Eqraft grading and packaging installations relies on scheduled preventive maintenance and timely replacement of high-wear parts.

On Eqrader platforms, inspection focuses on soft conveyor cups, optical camera lenses and drive belts, while Topper units require periodic knife and screen damper inspection.

Comprehensive overhaul kits provide timing belts, V-belts, sealed bearings, pneumatic gripper cylinders and inductive sensors. Specifying matching components relies on the machine serial number and equipment model stamped on the factory nameplate issued by Eqraft B.V. in Emmeloord, the Netherlands.
