Berkel Europe Model 20

Manufactured at the Van Berkel’s Patent factory in Rotterdam, Holland, between 1928 and 1936, the Berkel Model 20 stands as a magnificent example of precision mechanical engineering. Closely related to its American counterparts produced at the La Porte plant in Indiana—the U.S. Berkel Model C and the subsequent U.S. Berkel Model 11—the Model 20 is renowned for its advanced carriage movement and exceptional slicing accuracy.

Vintage Berkel Model 20: Engineering Excellence in Flywheel Slicers (1928–1936)

Manufactured at the Van Berkel's Patent factory in Rotterdam, Holland, between 1928 and 1936, the Berkel Model 20 stands as a magnificent example of precision mechanical engineering. Closely related to its American counterparts produced at the La Porte plant in Indiana—the U.S. Berkel Model C and the subsequent U.S. Berkel Model 11—the Model 20 is renowned for its advanced carriage movement and exceptional slicing accuracy.

Mechanical Innovations & Key Features

  • Double Connecting Rod & Carriage Synchronism: The machine features an intricate double connecting rod mechanism beneath the carriage. The main movement rod is synchronized with a second cam connecting rod, driving the balance system and pawl gear for smooth, exact carriage travel.

  • Worm Screw & Dual Transport Movement: The worm screw is positioned under the front carriage near the flywheel. Product tray movement can be controlled either via a right-hand lever on the worm screw for fine adjustment or a center-mounted lever for rapid repositioning.

  • Slice Thickness Range: Cutting synchronism is regulated at the top right of the carriage, offering 14 or 28 positions (depending on the version) to achieve razor-thin to generous cuts ranging from 0.27 mm to 3.7 mm.

  • Rail & Wheel Guidance: The carriage glides smoothly across the machine body using three precision metal wheels guided by a built-in base rail.

  • Blade & Opal Receiving Plate: Equipped with a 370 mm blade, a built-in waste collection drawer at the base, and a white opal glass tray fixed to the lower shoulder for receiving sliced products.

  • Shoulder Evolution: The integrated blade sharpener matches period-correct mechanics, while the shoulder design evolved over time: early versions share the profile of the U.S. Model C, while later variations closely resemble the U.S. Model 11.

Museum-Grade Restoration by The World's Best Slicers

Restoration work carried out in The World's Best Slicers laboratories follows strict historical conservation standards:

  1. Precision Machining & Conservation: Each unit is completely disassembled. Worn components are salvaged using material deposition welding followed by custom milling and turning to return parts to original factory dimensions without unnecessary replacements.

  2. Authentic Vintage Parts: Missing pieces are sourced exclusively from historic production stock or period-correct donor machines.

  3. Eco-Friendly Surface Prep & Paint: Castings undergo cryo-stripping and surface preparation before receiving eco-friendly modern coatings reformulated to match historical color shades.

  4. Authentic Copal Decals: Finishing artwork is strictly applied using period-correct copal paint decals—never vinyl stickers, airbrushing, or modern fantasy graphics.

Certificate of Authenticity: Every restored Model 20 is delivered with an Official Certificate of Originality and Guarantee, ensuring complete provenance for high-end collectors.
