Steam-based Pasteurization Tunnel Room Design

Note: Please read before bidding, I have mentioned all the details in the PDF so increasing the bidding price later will not be accepted.

Check the PDF attached for a detailed description.

Objective:
Design a pasteurization room that uses steam to heat 3,200 glass bottles (330 ml each) per batch. The goal is to uniformly raise the bottles from ambient temperature to the pasteurization temperature without localized overheating.

Key Details:
- Bottle & Pallet Setup:
Each crate holds up to 32 (330 ml each).
Each pallet holds 49 crates (7 crates by 7 crates configuration).
Pallet dimensions: 1200 mm x 1000 mm.

Room Layout:
- Designed with front and back doors to allow forklift loading/unloading inside the room.
- Insulated with PUF panels to maintain high thermal efficiency.
- Sufficient headspace required (approximately 2 ft) above the top crate for steam and water spray nozzles (for cooling).

Steam System:
- Direct steam injection with carefully placed nozzles to avoid hot spots and ensure uniform temperature distribution.
- Overhead water spray system for rapid cooling.

Deliverables:
- 3D Model & Layout of the room along with nozzles placed.
- Nozzle/Diffuser Placement & Specifications.
- CFD Analysis and Iterations to confirm uniform heating.
- Recommendation for sensor locations.
- Heating Time Estimates (time required to reach pasteurization temperature).

Required Expertise:
Mechanical or Chemical Engineer with expertise in steam-based systems, thermal processes, and CFD simulation.
