Natural Controlled Atmosphere

After Harvest – Natural Controlled Atmosphere Module for Fresh Produce Storage and Logistics

This is a flexible, eco-friendly controlled atmosphere (CA) technology designed to significantly extend the post-harvest shelf life, crispness, and quality of fresh fruits, vegetables, flowers, and mushrooms during storage and transport. Unlike traditional industrial controlled atmosphere systems that require expensive gas injection machinery, heavy electrical infrastructure, or chemical preservatives, the technology creates a self-regulating micro-climate directly inside stackable, modular pallet-boxes.

The system relies on a patented “Tiempo Cap” lid fitted with selective semi-permeable membranes. Placed inside a standard refrigerated room or reefer transport unit, the stored produce’s natural respiration drives the gas exchange, automatically stabilizing oxygen (O2) and carbon dioxide (CO2) levels between 1% and 5% while maintaining nearly 100% relative humidity. This dual optimization drastically slows cellular oxidation and eliminates moisture evaporation, reducing weight loss from standard 10–20% levels down to under 1.5%. The result is a highly adaptable, zero-chemical preservation system that allows growers, exporters, and logistics operators to shift sales windows, reduce post-harvest waste, and maintain field-fresh quality across long-distance distribution networks.

Summary
The technology provides a patented, low-energy post-harvest preservation technology that converts standard plastic pallet-boxes into individual controlled atmosphere storage units. By leveraging selective gas-permeable membranes and natural produce respiration, the system extends storage times by up to 2–5 times without chemical additives or active gas equipment. Deployed in over 35 countries, the technology empowers agricultural producers and logistics operators to mitigate market price volatility, reduce transit losses, and deliver premium produce to remote markets.
Full Specifications
  • Core Mechanism: Passive, natural Controlled Atmosphere (CA) generated via produce respiration and selective membrane diffusion.
  • Gas Regulation: Maintains optimal internal gas equilibrium (O2 and CO2 stabilized at 1%–5%) tuned specifically to the commodity.
  • Humidity Control: Achieves near 100% relative humidity without mechanical misting, preserving crunchiness and structural turgor.
  • Dehydration Reduction: Limits storage weight loss due to moisture evaporation to under 1.5% (compared to standard losses of 10%–20%).
  • Modular Capacity & Form Factor: Standard industrial 610-liter rigid HDPE pallet-boxes equipped with stackable Tiempo Cap lids.
  • Transport Optimization: Modules (e.g., JMT US 9 series) feature nestable/stackable designs, reducing empty return volume by up to 75%.
  • Infrastructure Requirements: Operates within standard cold rooms; requires zero external gas supplies, vacuum pumps, or dedicated electrical wiring.
  • Commodity Versatility: Certified for over 25 fruit types, 20 vegetable varieties, fresh herbs, mushrooms, and cut flowers.
  • Monitoring Systems: Supported by handheld gas analyzers (Tiempo Test series) for non-destructive O2/CO2 level monitoring.
