Specialty Coffee Vending Machine Design

Hello,

We have completely redesigned the machine concept and working methodology. The new approach is aligned with a regular bean-to-cup coffee vending machine, upgraded for specialty coffee output with dual ordering capability (two drinks simultaneously) using two displays and two side-by-side cup dispensing stations.

The system has been simplified significantly by removing CNC/gantry, conveyor, and robotic mechanisms, and is now based on a static modular architecture with pump + pipe-based fluid delivery.

UPDATED SYSTEM OVERVIEW:

• Dual cup dispensing system (left & right)
• Two independent serving positions for parallel output
• Two user interfaces (dual ordering screens)

• Centralized internal modules:

- Coffee grinder + automatic brew group (piston-based with waste ejection)
- Milk tank + heating + frothing system
- Water system

• Fluid delivery:
Tank → Pump → Valve → Pipe → Cup (for both lines)

---

WORKFLOW:

• Dual cup dispensing
• Grinding → brewing (automatic brew group cycle)
• Coffee delivered via piping
• Milk heating & frothing
• Milk dispensed via piping
• Final output at respective station

SCOPE — INCLUDED (IMPORTANT):

2D Engineering Drawings:

- Top, front, and side views with dimensions
- Sectional view showing internal layout

3D CAD Model:

- Complete machine assembly
- Dual cup system
- Internal module placement

Mechanical Design (Basic to Intermediate Level):

- Brew group integration (not redesign from scratch, but proper placement and mechanism understanding)
- Cup dispensing mechanism concept
- Structural layout and mounting approach

Fabrication-Level Drawings (Basic):

- General fabrication drawings for structure and paneling
- Not ultra-detailed production drawings, but build-understanding level

Electrical & Control Architecture (Concept Level):

- Basic control logic flow
- System architecture (PLC/microcontroller level)
- No detailed wiring diagrams required

BOM (Basic/Indicative):

- Major components list:
- pumps
- valves
- grinder
- brew group
- tanks
- No vendor-level deep sourcing required

Fluid System Design (Concept Level):

- Pipe routing
- Pump placement
- Flow direction
- No detailed pressure/thermal calculations required

---

CLEAR LIMITATIONS (TO CONTROL SCOPE):

• No highly detailed component-level mechanical drawings
• No full electrical schematics or panel wiring
• No advanced simulations (thermal/pressure)
• No prototype manufacturing support

---

EXPECTATION:

The output should be:
• Practical and manufacturable
• Clear for next-stage engineering
• Well-structured and modular
• Suitable for vendor discussion and prototype planning

Considering the major simplification in machine architecture and reduced mechanical complexity, I request you to kindly re-evaluate and provide a revised quotation based on this updated scope.

Happy to walk you through the updated design if needed.
