Periodic Reporting for period 3 - MAX-FRESH (Maximizing freshness and minimizing losses of agriculture products through automated atmosphere management in storage facilities)
Okres sprawozdawczy: 2022-10-01 do 2024-03-31
In the MAX-FRESH project, we will develop the innovative ISS-Monitor: world’s first automated multi-species trace gas sensor that can simultaneously and in real-time detect low levels of 7 volatile gases that indicate ripening, fermentation, damage or rotting of stored fruit.
Once unfavorable conditions are detected, the ISS-Monitor will provide automated alerts to enable timely and effective interventions by its customers. The ISS-Monitor has the potential to reduce losses of stored fresh food by 50%, extend storage life with 20%, and reduce post-harvest chemical treatments with 50%.
The MAX-FRESH project builds on a functional prototype of the ISS-Monitor which demonstrated proof-of performance in a relevant environment. During the MAX-FRESH project, we will take the final steps required to launch the ISS-Monitor on the market. To do so, we apply for €2.2 million (77%) from the EC. The MAX-FRESH project will be performed by a complementary consortium of 3 market-leading industrial partners and 1 academic partner, combining cutting-edge technologies with unique expertise. After completing the MAX-FRESH project in 2023, the ISS-Monitor will be ready for market launch. By doing so, the ISS-Monitor will make an impact on the global food production system by contributing to sustainable food production for the ever-growing world population.
The shared goal of the MAX-FRESH consortium is to introduce a commercially viable version of the ISS-Monitor on the market upon completion of this project. To reach this goal, the following project objectives have been set:
Objective 1: Industrial prototyping of the existing advanced ISS-Monitor towards a commercially viable model that meets all technical, qualitative and quantitative requirements.
Objective 2: Optimize software and user-interface of the ISS-Monitor system for automated analysis and alerts and to ensure compatibility and easy integration with current storage monitoring and control equipment.
Objective 3: Set up and scale up ISS-Monitor manufacturing for demonstration and commercialization purposes, and verify that ISS-Monitor meets all regulatory requirements and specifications.
Objective 4: Validate and demonstrate the ISS-Monitor in an operational environment.
Objective 5: Perform business development activities to optimally prepare for market launch and commercialization of the ISS-Monitor.
Three mid-infrared supercontinuum lasers with a total average power of ~450mW, tailored for ISS monitoring systems, were built, tested, and delivered to RU. During RP3, their spectral densities were optimized to maintain uniformity with the RP2 lasers. A compact "Module-laser" was also developed, but its optical power spectral density limited its use in current ISS systems. Additionally, most engineering time in RP3 focused on developing the silica-ZBLAN splice recipe, crucial for the ISS laser's reliability and longevity.
The 3rd MPC version improved on its predecessors but still had issues, particularly with the transmitted laser beam stability necessary for system calibration. Unforeseen outcomes required live testing through three additional design iterations until the project's performance goals were met. To ensure beam stability in a vacuum, the internal volume was doubled, which allowed for screws instead of glue to secure the mirrors. This design change simplified production and reduced labor time, also benefiting end users by making mirror maintenance, such as cleaning, easier.
The ISS2 monitor was completed and tested. The laser's temperature control box malfunctioned, causing instability due to thermal effects. This was resolved by adding tubing for additional isolation and adjusting the laser box's TEC to keep the inner fan running, reducing thermal inertia. The LabView software (ISSPro) was partially rewritten to replace dysfunctional code and improve error handling. Long-term system tests were conducted to identify and fix remaining bugs, with an enhanced fitting algorithm introduced to handle nonlinear baselines. An email service was set up to send daily measurements in Excel format.
After initial testing and bug fixing, ISS2 was moved to WUR in Randwijk for validation, with ongoing support provided. ISS3 was assembled, and the assembly documentation was improved. Additional operational and software manuals were written. Finally, after a service check-up, ISS1 was successfully installed at a storage facility in Belgium.
