Forced-Air Pre-Cooling & Cold Room Monitoring

1. Overview & Business Value#

This comprehensive operational guide details the architecture, business workflows, configuration parameters, and execution steps for Forced-Air Pre-Cooling & Cold Room Monitoring within SmartERP.

Operate forced-air pre-cooling tunnels, monitor ambient temperature sensors, prevent condensation, and maintain 2°C–4°C cold rooms.

2. Prerequisites & Security Access Groups#

• Required Modules: smarterp_commodity_export, smarterp_agri_traceability
• Security Groups:
  • Cold Chain & Packhouse Officer (Technical ID: smarterp_export.group_export_user)
  • Floriculture Quality Inspector (Technical ID: smarterp_export.group_export_qa)
  • Floriculture Export Manager (Technical ID: smarterp_export.group_export_manager)
• Master Data Dependencies: Greenhouse greenhouse blocks, rose stem varieties, cold storage temperature telemetry (2°C–4°C), Ethiopian Airlines Bole Cargo space bookings, and European auction buyers.

3. Step-by-Step Configuration & Execution#

Step 1: Navigating to the Module Interface#

1. Log into your SmartERP instance at https://smarterp.et/odoo.
2. Open the main App Switcher (grid icon in the top-left corner).
3. Select the Floriculture Export app icon.
4. From the top navigation bar, open Floriculture Export → Greenhouse → Harvest / Cold Chain / Packhouse / Air Waybills.

Step 2: Creating and Parameterizing Records#

1. Click the New button in the top-left control panel.
2. Complete the mandatory fields in the record form:
   • Greenhouse Harvest Batch (Mandatory): Block origin, stem length (cm), and cut date/time
   • Rose Variety & Head Size (Mandatory): Commercial cultivar (Rhodos, Red Naomi, Athena) and bud profile
   • Pre-Cooling Verification (Mandatory): Confirmed forced-air cooling record achieving 2°C–4°C core temperature
   • Bole Cargo e-AWB Number (Mandatory): Ethiopian Airlines booked air waybill identifier
3. Configure optional operational parameters and localized tags as required:
   • Cold Chain Logger ID (Optional): Digital temperature datalogger serial number placed in pallet
   • Auction Consignment Code (Optional): Royal FloraHolland auction lot reference
   • MoA Phytosanitary Seal Number (Optional): Official government export inspection security tag
4. Click the Save icon in the control bar to commit the record.

Step 3: Validating and Processing Transactions#

• State Transitions: Execute operational state progression (Harvested → Pre-Cooled (2°C) → Packhouse Sorted → Cold Truck Transit → Bole Airport Loaded → Cleared).
• Ledger & System Impact: Direct greenhouse labor and packaging costs absorb into crop inventory; e-AWB air freight dispatch recognizes export revenue in foreign currency.
• Audit Verification: Automated recording of author ID, timestamp, and immutable revision history.

Forced-Air Pre-Cooling Dynamics#

Placing packed boxes into static cold rooms results in sluggish heat removal (taking up to 24 hours), causing internal flower sweating and botrytis fungal outbreaks. SmartERP manages Forced-Air Pre-Cooling Tunnels:

• Packed cartons are stacked in parallel rows with an exhaust tarp drawn over the top.
• Powerful centrifugal exhaust fans pull chilled cold-room air through the carton vent holes directly across the flower heads.
• Pulldown temperature from $18^\circ C$ to $< 3.5^\circ C$ completes in 45 to 60 minutes.

Continuous IoT Sensor Telemetry in SmartERP#

SmartERP integrates with Modbus and LoRaWAN wireless temperature sensors:

• Real-time dashboards track temperature and relative humidity ($RH\%$) at 5-minute intervals.
• If cold room temperature rises above $5.0^\circ C$ for more than 15 consecutive minutes:
  • An emergency audio-visual alert sounds in the facility control room.
  • Urgent SMS dispatches to the refrigeration maintenance engineer.

4. Advanced Configuration Points#

• Automated Actions & Scheduled Tasks (Crons):
  • Cold Chain: Alert temperature breach above 4°C (smarterp_export.ir_cron_temp_monitor): Runs every 15 minutes checking IoT temperature telemetry
  • Air Cargo: Track Bole cargo flight departure (smarterp_export.ir_cron_flight_status): Runs hourly checking Ethiopian Airlines cargo flight tracking
• Custom Print Templates & Reports:
  • Cold Chain Temperature Compliance Certificate
  • MoA Phytosanitary Export Inspection Dossier
  • Bole Cargo Air Waybill (e-AWB) & Pallet Manifest
  • Consignment Net Realization & Auction Settlement Summary
• Multi-Company Rules: Record-level security isolation under Company 1 (Ashewa Technology Solutions S.C.), preventing cross-company ledger leakage across parent and subsidiary legal entities.
