Newin NW-WK-RO7 7L Commercial Food Chopper is built for kitchens that process 30-50 kg of vegetables, herbs, or nuts per shift. As a core unit in our hachoir à légumes line, it handles bulk prep for restaurants, central kitchens, and small-scale food processing — no pre-cutting required for most ingredients.
The 750W motor drives a hardened stainless steel S-blade at 1,500 RPM. Bowl is food-grade 304 stainless — not coated aluminum. That matters. Coated bowls chip over time. Solid stainless doesn’t. 7 liters net capacity. For operations needing finer particle control, bol hachoir units with higher RPM and emulsifying capability are available in the same product family.
Dual voltage. 110V/60Hz or 220V/50Hz. (Voltage configuration must be specified at order.) 27 kg net weight — the cast-iron base keeps the unit stable at full speed. No suction cups. No clamping. One person can lift it for cleaning. If your volume exceeds 80 kg/day, contact our team for the 15L or 25L capacity models.
Spécifications techniques
| Paramètre | NW-WK-RO7 | Pourquoi c'est important |
|---|---|---|
| Modèle | NW-WK-RO7 | Identifies the specific 7L capacity unit within the Newin chopper range |
| Pouvoir | 750W | Delivers 1,500 RPM blade speed — enough torque to chop frozen-trimmed vegetables and hard nuts without stalling. Equivalent to 1 HP output. |
| Tension | 110V/60Hz or 220V/50Hz | Dual voltage means no external transformer needed. Specify at order — factory configures accordingly. (North America 110V, Europe/Asia 220V standard.) |
| Capacité | 7L (Net) | Handles 3-4 kg of raw vegetables per batch. Real throughput: 30-50 kg/hour depending on ingredient density. Enough for a 200-cover restaurant’s daily prep. |
| Bowl Material | Acier inoxydable SUS304 | Food-grade 304 stainless resists acid corrosion from tomatoes, citrus, and vinegar-based marinades. No coating to peel into food over time. |
| Matériau de la lame | Hardened Stainless Steel (S-blade) | S-curve blade geometry creates dual cutting zones — bottom edge chops, upper curve pulls ingredients downward for uniform particle size. No unprocessed chunks left above the blade. |
| Poids net | 27 kg | Cast-iron base weight eliminates vibration at full speed. No suction cups needed. The unit stays put on stainless prep tables. Heavy enough to feel solid, light enough for one person to reposition. |
| Dimensions | 310 × 345 × 480 mm | Compact footprint. Fits under standard 600 mm deep countertops. 480 mm height leaves clearance for wall-mounted shelves in small kitchens. |
| Taille du paquet | 440 × 405 × 570 mm | Export carton with 30 mm high-density foam. Stackable 2-high on pallet. 54 units per 20ft container (palletized). |
| Vitesse | 1,500 RPM | Single speed, direct drive. No belt to slip or replace. On/off + pulse function via magnetic safety switch — cover must be locked for motor to engage. |
Newin NW-WK-RO7 vs Industry Standard: What the Specs Actually Mean
| Fonctionnalité | Typical Entry-Level Chopper | Newin NW-WK-RO7 | Real Impact |
|---|---|---|---|
| Puissance du moteur | 500W | 750W | 50% more torque. Chops hard ingredients (carrots, nuts, frozen-trimmed vegetables) without bogging down. 500W units stall on dense loads. |
| Bowl Material | Coated Aluminum / 201 Stainless | Acier inoxydable SUS304 | Coated aluminum bowls degrade within 6-12 months of acidic ingredient contact. 304 stainless is rated for commercial dishwasher cycles and acidic food contact — no coating to peel. |
| Base Stability | Rubber suction feet (12-18 kg) | Cast-iron weighted base (27 kg) | Suction cups lose grip on wet or oily surfaces. Weight-stabilized design stays planted regardless of countertop condition. 27 kg absorbs vibration — not just dampens it. |
| Voltage Flexibility | Single voltage (220V only) | Dual voltage 110V/220V | No step-down transformer needed for 110V markets (North America, Japan, Taiwan). Reduces per-unit landed cost by $30-80 vs transformer-dependent setups. |
| Mécanisme de sécurité | Mechanical microswitch | Magnetic safety interlock | Magnetic switch is sealed — no exposed contacts that corrode in humid kitchen environments. Mechanical microswitches fail after 1-2 years of steam exposure. |

Core Component Breakdown
🔪 S-Blade Assembly — Hardened Stainless Steel
- Matériel: SUS420J2 stainless steel, hardened to HRC 52-55
- Geometry: Dual-curve S-profile. Lower edge chops, upper curve pulls ingredients downward. No unprocessed material left above the blade plane.
- Avantage: HRC 52-55 hardness holds edge through 200+ hours of vegetable processing. Blade replacement is tool-free — spin off the locking nut, swap, re-tighten. 30 seconds.
⚡ 750W Pure Copper Motor — Direct Drive
- Type : Single-phase induction motor, 100% copper winding
- Sortir: 750W input, ~1 HP equivalent mechanical output at 1,500 RPM
- Avantage: Copper windings vs aluminum: 40% lower resistance, 15°C cooler operating temperature under continuous load. Aluminum-wound motors degrade faster in humid kitchen environments. Direct drive — no belt tension to adjust, no belt to slip or replace.
🛡️ Magnetic Safety Interlock
- Type : Sealed magnetic reed switch
- Mécanisme : Bowl lid must be fully seated and locked for the magnetic circuit to close. Motor cannot engage with lid open or misaligned.
- Avantage: Sealed design — no exposed mechanical contacts. In high-humidity kitchens, mechanical microswitches corrode and fail within 12-18 months. Magnetic reed switches are rated for 100,000+ cycles. No maintenance.
🏋️ Cast-Iron Weighted Base
- Matériel: Cast iron with epoxy powder coat
- Weight Contribution: ~12 kg of the total 27 kg
- Avantage: Mass-dampened stability eliminates the need for suction cups or clamps. The base stays planted on wet, oily, or uneven stainless prep tables. Epoxy coating resists chipping and is rated for commercial kitchen cleaning chemicals.
Where the NW-WK-RO7 Fits
Chop onions, garlic, herbs, and vegetables for 150-200 covers per shift. 7L bowl handles 3-4 kg per batch. Pulse function for coarse or fine texture control.
Salsa, pesto, hummus, nut butters — 30-50 kg/hour throughput. SUS304 bowl handles acidic ingredients (tomatoes, citrus, vinegar) without corrosion.
Batch prep for 500+ meal services. Dual voltage means one SKU covers both 110V and 220V markets. 27 kg base stays stable during continuous operation.
Nuts, dried fruits, breadcrumbs. 750W motor handles dense loads without stalling. Blade speed optimized for chopping — not puréeing — so you get uniform particle distribution.
Blade life: The S-blade holds its factory edge for roughly 200-250 operating hours under normal vegetable processing. When chop consistency degrades — particles become uneven, some chunks remain unprocessed — it’s time to swap. Replacement takes 30 seconds. No tools.
Bowl cleaning: SUS304 is dishwasher-safe. But hand-wash the blade separately. Dishwasher detergents at 70°C+ will micro-pit the cutting edge over time. Rinse, dry, store. Ten seconds.
Motor cooling: The 750W motor has a thermal overload protector. If the unit stops mid-batch during heavy continuous use, it’s not broken — the thermal cutoff triggered. Let it cool 15 minutes, reset, continue. If this happens frequently, reduce batch size or increase rest intervals between cycles.
Lid seal: The silicone gasket on the bowl lid is a wear item. Inspect every 3 months. If visible cracks or flattening appear, replace. A failed seal lets moisture into the motor housing. Gasket replacement is a $3 part.
Foire aux questions
Q: What is the real daily throughput of the Newin NW-WK-RO7 food chopper?
A: Newin NW-WK-RO7 processes 30-50 kg of vegetables per hour depending on ingredient density. For soft vegetables (onions, tomatoes, herbs), expect the upper end. For hard ingredients (carrots, nuts), plan for 30-35 kg/hour. The 7L bowl holds 3-4 kg per batch. A 200-cover restaurant typically runs 4-6 batches during morning prep.
Q: Can the Newin NW-WK-RO7 handle frozen ingredients?
A: Newin NW-WK-RO7 is designed for fresh and tempered ingredients. It handles frozen-trimmed vegetables (surface thawed, core still cold) without issue. Fully frozen blocks (-18°C) are not recommended — the S-blade geometry is optimized for chopping, not ice crushing. For frozen meat processing, Newin’s frozen meat grinder line is the correct equipment.
Q: What is the MOQ and lead time for the Newin NW-WK-RO7?
A: Newin NW-WK-RO7 MOQ is 1 unit — distributor samples are accepted. Sample lead time: 5-7 days after voltage confirmation. Bulk orders (10+ units): 12-15 days. Container orders (20+ units): 20-25 days with tiered pricing. Sea freight from Shanghai, air freight available for urgent samples.
Q: How does the dual voltage work on the NW-WK-RO7?
A: Newin NW-WK-RO7 is factory-configured to either 110V/60Hz or 220V/50Hz — not switchable in the field. Voltage must be specified at order. The motor winding is wound for the target voltage during assembly. This means no external transformer is needed. North American buyers select 110V; European, Asian, and Middle Eastern buyers select 220V.
Q: How does the NW-WK-RO7 compare to a bowl chopper or vegetable cutter?
A: Newin NW-WK-RO7 is a vertical food chopper — best for chopping, mincing, and coarse puréeing. A bowl chopper (higher RPM, emulsifying capability) is better for fine pastes and meat emulsions. A vegetable cutter with interchangeable discs is better for uniform slices, shreds, and dices. The NW-WK-RO7 sits in the middle: faster than manual prep, more versatile than a single-purpose slicer, less specialized than a high-speed bowl chopper.
Q: Can I customize the Newin NW-WK-RO7 with my brand logo?
A: Newin NW-WK-RO7 supports OEM customization. Laser-engraved logo on the base housing: MOQ 20 units. Custom color (beyond standard silver): MOQ 50 units. Plug type (US/EU/UK/AU): no MOQ, specified at order. Full ODM with custom packaging and manual: MOQ 100 units. Request a quote with your customization requirements.
