Questions for RFP

Questions to answer per subsystem and subassembly. Use this list to flush out parameters, tolerances, and missing specs before or during RFP work.

1. Fruit intake system

What are the full parameters and tolerances for the feeder body, 90° entry tube (with CIP nozzle), and external duct (oranges from hopper)?
Top-level feeder: photos and Q&A for components not yet covered by the feeding subassembly?
How does the feeder body interface with the enclosure and the extraction/sync fruit support?

CIP vertical cut-out for spray nozzle: when will it be added to CAD, and what are the exact dimensions/position?
90° pipe: confirm equivalent China-available standard (3″ NPS / 90 DN Schedule 5S, 88.9 mm OD, 2.11 mm wall) and supplier.

Fruit support: Confirm target 8° rail angle (vs current 3°) and any tolerance. When will this be updated in CAD?
Fruit support pusher: Proceed with a formed component instead of cut/welded sheet? Material and form spec?
Chute deflectors (WIP): Final geometry and mount details to avoid collision during motion? Material and manufacturability (bent plate)?
Parameters and tolerances for driven bracket (yoke mount holes, alignment to static peelers)?
Parameters and tolerances for driven peelers and central pin?

Yoke: full interface tolerance with cam bearings (drivetrain) and extraction/sync? Alignment to frame?
35 mm drive shafts and LMK35UU bearings: axial location, preload, and mount tolerances?
Transmission mount plate: H7/dowel or other alignment to frame?

34 mm standard connector for juice collector Y-tube: exact part number or spec to send to manufacturer?
Static deflectors (WIP): Final flat-plate geometry, mount to static loaded plate, and clearance vs chute deflectors? Material and manufacturability?
Static peelers: mesh tolerance with driven peelers? Material and finger geometry?
Filter tube: slot dimensions and tolerance for juice flow and plunger pass-through?
Plug cutter: interface tolerance with core ejection plunger and core chute?

Plunger: stroke, diameter, and tolerance with filter tube and plug cutter?
Plunger drive bracket and rods: interface with drivetrain/transmission cycle? 178 mm range confirmation?
Juice outflow collection: routing, connections, and cleanability?

Sumitomo Cyclo 6000 reducer: Provide full specs (ratio, torque, mounting, shaft dimensions).
WEG 22 1450 rpm motor: Provide full specs (power, frame, shaft, protection, terminal box).
V-belt (DIN 2215 17×957, 2-belt, 1000 mm): tensioning procedure and replacement interval?
Cam bearings: interface tolerance with transmission yoke? Lubrication and service?

Peel chute and core chutes: material (e.g. folded sheet), weld spec, and interface with collection/core ejection?
Augers: speed, torque, and interface with third-party equipment (Jiangxi line)?

Loaded mount plate, transmission mount plate, drivetrain mount plate: final H7/dowel positions and assembly sequence?
Leveling feet (6111K669 M24): confirm quantity and load rating for JX floor?

Overcentered hinges: The feeder, drivetrain lid, and plunger lid use overcentered hinges (open position when open, pressure down when shut). Springs and assembly method for these hinges are not designed yet — specify spring type, preload, pivot geometry, and assembly/fastening method.
Plunger cover (#BC4944) and drivetrain cover (#489C26): confirm interface with frame and hinge mounting points; any gasketing or sealing when shut?
Safety: lid switches (see Controls) and access for CIP/maintenance?

Nozzle positions at each peeler and at each 90° tube: flow rate and spray pattern spec?
Pipes feeding CIP nozzles: routing, material, and connection to third-party CIP equipment?

Yoke position / cycle: Encoder or other position detection for cycle and controlled stop — specify solution (TBD / needs further development).
WEG W22 motor: spec sheet and integration with contactor/starter?
Lid safety switches: quantity, position, and interlock logic?

Material for every component: confirm list per subsystem.
Manufacturing method per part (e.g. formed vs welded for fruit support pusher).
Fasteners: Full selection and assembly process per joint.
Tolerancing: How will manufacturers achieve critical interfaces (e.g. H7/dowel)? Post-processing (ream, etc.)?
CAD: Inventor → SolidWorks transition — what is the timeline and who owns conversion?

Jiangxi: confirm interface with Kaiyi or similar orange juicing line (feed in, peels/juice out).
Equipment context: JBT Marel–style; assume Chinese equipment interfaces — any specific standards or connectors?

When answering the questions above, tie evidence to subsystem pages. Gaps that commonly need photos or diagrams:

Add figure: Per-subsystem "proof pack" — one sheet per major interface (feeder in, juice out, CIP, electrical) with dimensions.
Add figure: Alignment / dowel workflow — photos or CAD for frame → plates → peelers chain.
Add figure: DFM risk callouts — welds, drains, and washdown dead zones you want the contractor to address.
