CURPOD SPACE SAVR Controlled Atmosphere Curing & Storage Chamber

Overview

The CURPOD SPACE SAVR is a precision-engineered, stainless steel controlled atmosphere chamber designed specifically for post-harvest curing, stabilization, and long-term storage of sensitive botanical biomass—particularly high-value horticultural and herbal materials requiring terpene preservation and microbial inhibition. Unlike ambient or refrigerated storage systems, the SPACE SAVR operates on a closed-loop modified atmosphere principle: it actively depletes oxygen using bottled nitrogen while dynamically regulating CO₂, relative humidity (RH), and temperature via integrated electro-pneumatic valves and centrifugal air circulation. This enables reproducible, data-locked environmental control across extended timeframes—critical for standardizing shelf-life extension, reducing spoilage, and maintaining organoleptic integrity. The system’s vertical architecture and hinged airtight door optimize floor-space efficiency in commercial drying/curing facilities where square-footage cost is a primary operational constraint.

Key Features

• Airtight 304 stainless steel enclosure with gasketed, pressure-rated door—validated for sustained sub-ambient O₂ environments (typically <1% O₂)
• Eighteen (18) standardized RPC slots (15.5″ × 23.5″ × 7.75″) supporting up to 95 lbs of product per unit—designed for seamless integration with existing harvest logistics
• Onboard multi-parameter sensing: electrochemical O₂ sensor (0–25% range), NDIR CO₂ sensor (0–10% range), capacitive RH sensor (10–95% RH), and PT100-class temperature probe (±0.3°C accuracy)
• Programmable dual-gas modulation: independent control of nitrogen inflow and ambient air bleed to achieve and maintain user-defined O₂/CO₂ setpoints without external gas mixing hardware
• Cloud-native firmware with TLS-encrypted MQTT communication—enables remote monitoring, parameter adjustment, and alarm notification via web or mobile interface
• Full-cycle data logging: timestamped readings stored locally (SD card backup) and synchronized hourly to encrypted cloud storage with immutable audit trail
• Automated terpene preservation protocol: maintains low-O₂, moderate-RH (55–65%), and stable temperature (15–20°C) profiles validated to minimize chlorophyll degradation and sugar hydrolysis while maximizing monoterpene and sesquiterpene retention

Sample Compatibility & Compliance

The CURPOD SPACE SAVR accommodates intact or lightly processed plant material—including whole flower, trimmed bud, and cured leaf—in standard RPC containers. Its sealed architecture eliminates cross-contamination between batches and prevents mechanical damage during handling. From a regulatory standpoint, the system supports Good Manufacturing Practice (GMP)-adjacent workflows through its deterministic environmental control and traceable data lineage. While not FDA-cleared as a medical device, its logging architecture complies with foundational elements of 21 CFR Part 11 (electronic records/signatures) when deployed with organizational access controls and periodic validation protocols. Exported CSV logs meet ASTM D8199-22 requirements for environmental condition documentation in agricultural post-harvest applications.

Software & Data Management

The embedded Linux-based controller runs proprietary firmware with RESTful API endpoints for integration into enterprise LIMS or ERP platforms. The cloud dashboard provides concurrent visibility across multiple CURPOD units—operators can view live sensor overlays, compare historical profiles between chambers, and trigger manual overrides or profile swaps. All data exports include ISO 8601 timestamps, sensor calibration metadata, and firmware version stamps. Audit logs record every configuration change, user login, and alarm event—retained for ≥24 months unless manually purged under documented data retention policy. No local software installation is required: browser-based access works on Chrome, Edge, or Safari (v95+).

Applications

• Standardized post-harvest curing of cannabis and hemp biomass to ensure batch-to-batch consistency in moisture equilibration and terpene stability
• Extended shelf-life storage of premium culinary herbs (e.g., basil, mint, oregano) without freeze-drying or vacuum packaging
• Controlled oxidation management for tobacco leaf aging under defined O₂/CO₂ partial pressures
• Research-grade environmental stress testing of plant metabolites under replicated low-O₂, high-N₂ conditions
• QC hold storage for analytical reference materials requiring 12-month stability under inert atmosphere

FAQ

Does the CURPOD SPACE SAVR require external gas mixing equipment?
No. It uses direct nitrogen injection with proportional air bleed—no external blender, mass flow controllers, or CO₂ cylinders are needed.
Can I integrate CURPOD data into my existing SCADA or MES system?
Yes. The REST API and MQTT broker support structured JSON payloads compatible with Ignition, Siemens Desigo, and Rockwell FactoryTalk environments.
What is the calibration interval for onboard sensors?
O₂ and CO₂ sensors are factory-calibrated with recommended field verification every 90 days using certified span gases; RH and temperature sensors retain ±1% and ±0.3°C accuracy over 12 months per ISO/IEC 17025 traceable certificate.
Is the cloud dashboard hosted in a HIPAA- or GDPR-compliant environment?
Data residency is configurable: customers may select AWS us-east-1 (HIPAA-eligible) or eu-west-1 (GDPR-aligned) regions during onboarding.
How is firmware updated?
Over-the-air (OTA) updates are delivered via signed packages; each release includes SHA-256 checksums and changelogs accessible in the admin portal prior to deployment.
