Berkel Europe Model 9HP Slicer: History, Specs & Restoration

The Berkel Model 9HP flywheel slicer was manufactured between 1936 and 1948 by Maatschappij van Berkel’s Patent N.V. in Rotterdam, Netherlands. Celebrated for its unique mechanical innovations, the Model 9HP features an impressive automatic product-laying mechanism, representing a pinnacle of mid-20th-century Van Berkel engineering.

Technical Features & Mechanical Innovations

• Automatic Product Discharging System: Equipped with an intricate mechanical assembly featuring pointed open discs that catch the freshly cut slice, rotating it toward the collection area, where an open hand-shaped tool places the slice neatly onto the tray.

• Carriage & Bakelite Guides: The carriage slides smoothly along the left side via metallic wheels rolling on a black bakelite guide cast directly into the main machine housing.

• Quick-Release Clamping Carriage: Features an open-type articulated arm, a stainless steel meat plate with an instant coupling mechanism, and an automatic carriage release system at the end of the cutting stroke.

• Protected Helical Gears: Engineered with protected helical drive gears and a covered lead screw (worm gear) for extended longevity and smooth operation.

• Closed Flywheel: Operates via a 340 mm external diameter closed flywheel, decorated internally with the official decal "Van Berkel's Patent".

• Slice Thickness & Sharpener: Driven by a precise 15-position snap-on clock dial regulator, paired with a detachable automatic sharpening assembly.

• Original Finishes: Originally produced in Red, Black, and Ivory colorways.

The Berkel Model 9HP Pedestal

Originally designed for countertop operation, the original Berkel pedestal was offered as an optional accessory. Pairing the slicer with its authentic pedestal allows optimal placement anywhere in the room without taking up counter space, simplifies cleaning, and elevates the striking mechanical presence of the Model 9HP.

Expert Restoration Process by "The World's Best Slicers"

Every Berkel Model 9HP restored in the laboratories of The World's Best Slicers undergoes an uncompromising, museum-grade conservation process:

1. Mechanical Conservation & Recovery

• Conservation First: Complex mechanical components—including the slice-laying disc assembly—are painstakingly repaired and recovered rather than discarded or replaced whenever possible.

• Precision Machining: Components undergo material deposition welding followed by custom turning or milling to restore exact original factory dimensions and mechanical functionality.

• Authentic Replacement Parts: Missing elements are replaced exclusively using original spare parts sourced from historical facilities or period donor machines.

2. Surface Preparation & Eco-Friendly Painting

• Cryo-Stripping: Non-abrasive cryogenic paint removal strips away legacy coatings while protecting the structural integrity of the underlying cast iron.

• Eco-Compliant Paints: Repainted using non-toxic, eco-compliant modern coatings precisely color-matched to historical Berkel color formulas (Red, Black, or Ivory).

3. Traditional Decals & Pedestals

• Authentic Copal Decals: Artwork and branding are applied strictly using traditional copal paint decals matching period color tones. We never use vinyl stickers, airbrushing, or unauthorized fantasy artwork.

• Authentic Pedestals: Supplied strictly with original period pedestals, avoiding non-historical reproductions.

Authenticity & Guarantee

Every restored Berkel Model 9HP is delivered complete with an Official Certificate of Originality and Guarantee, certifying its historical accuracy, mechanical precision, and long-term value.
