Peelers

Part of the Extraction & synchronisation section. Driven peelers and their mounting/alignment strategy to mesh with collection-side static peelers.

Introduction

Driven peelers mesh with static peelers (collection) during compression to perform extraction. The peeler core geometry is inherited from the commercial machine; the main open work is defining the mounting flange/plate fabrication and an alignment procedure that preserves concentricity and avoids collisions.

Colour key & components

Key components and intent (colours may vary across CAD figures).

Figures

Peeler context is shown in the Extraction main gallery. Add dedicated closeups here later.

• Add figure: driven peeler + fabricated flange/plate concept (lathe-machined flange + welded plate) with bolt pattern.
• Add figure: adjustment → ream workflow for concentricity (which holes are loose-fit vs which are reamed/shoulder-bolted).
• Add figure: clearance at end-of-stroke showing “no collision” requirement and acceptable gap.

Discussion

Rough design & intent

• Core geometry — Peelers are inherited from an existing commercial machine; the intent is to reuse the peeler geometry and build new mounting/adaptation hardware.
• Mounting strategy (open) — Fabricate a mount flange/plate for each peeler by machining a flange (lathe) and welding a plate so the peeler can be bolted to the driven bracket (driven side) or collection mount plate (static side).

Known issues & risks

• Concentricity & collision — Driven and static peelers must be aligned concentrically. Misalignment can cause collision at end-of-stroke and rapid wear.
• Weld distortion — Welding a plate to a peeler risks warping or shifting the peeler axis; fixturing and inspection are required.
• Washdown — This is in the splash zone. Mounting features and fasteners must be hygienic and cleanable.

DFM & manufacturing (China)

• Fixture and inspection — Contractor to propose fixtures for welding/machining the flange/plate and checks for axis runout/concentricity.
• Fasteners — Prefer hygienic fasteners (hex head) and avoid pockets that trap pulp.

Alignment workflow (owner intent)

1. Provide two loose-fit fastener holes (e.g., top-left and bottom-right corners) on each peeler mount for adjustment.
2. Adjust driven and static peelers relative to each other until concentric/aligned.
3. Tighten fasteners to lock, then drill + ream the other two corners through the peeler mount into the bracket/plate.
4. Install shoulder bolts (or dowels) in the reamed locations for repeatable alignment on reassembly.

Questions for contractor

1. Propose practical tolerances and an inspection method for peeler concentricity/alignment that prevents collision and controls wear.
2. Propose the best flange/plate fabrication method (machining route, weld method, fixturing) that preserves peeler axis accuracy.
3. Recommend whether shoulder bolts, dowel pins, or another locating scheme is best for repeatable reassembly in China fab practice.

Interfaces

• Input: Compression stroke from Transmission pushes extraction module into Collection.
• Output: Fruit extraction via driven-static peeler mesh; peel routed to disposal via deflectors/chutes.
• Mount: Driven peelers bolt to Driven bracket. Static peelers bolt to collection mount plate (see Collection).
