The post harvest respiration of fruits and vegetables is a core physiological process that affects their storage quality and shelf life. Research has shown that for every 10mg increase in respiratory intensity of CO ₂/kg · h, the storage period of fruits and vegetables is shortened by an average of 3-5 days. The fruit and vegetable respiration meter provides scientific basis for post harvest physiological research, storage condition optimization, and cold chain logistics management by monitoring key gas parameters such as CO ₂, O ₂, C ₂ H ₄ in real-time.

Typical application scenarios
Cold chain logistics: Real time monitoring of the respiration status of fruits and vegetables during transportation, dynamically adjusting temperature and humidity;
Supermarket retail: Optimize refrigerated display based on respiratory data to extend the shelf life of leafy vegetables;
Modified atmosphere packaging: By regulating the O ₂/CO ₂ ratio, it inhibits mold growth;
Research breeding: Establish a variety correlation database between respiratory intensity and storage tolerance.
In depth analysis of industry pain points
1. The traditional detection mode has four fundamental flaws:
Data isolation: It is difficult to conduct cross batch analysis through manual recording;
Environmental interference: Cold storage vibration affects the stability of infrared sensors;
High cost: Less than 10 batches of daily inspection and measurement for a single device;
Complicated operation: Gas sampling requires professional personnel and is difficult to popularize at the grassroots level.
2. The fruit and vegetable respiration meter completely solves these problems through the following innovative designs:
Dynamic flow control: automatically adjust the sampling flow rate (100-1000mL/min) to adapt to different volumes of breathing chambers;
Seismic structure design: Infrared sensor module suspended installation, stable operation in cold storage environment;
Cloud platform linkage: Real time detection data is uploaded to the enterprise ERP system to achieve automatic adjustment of preservation strategies;
Prefabricated breathing chamber: available in 5 sizes (0.5-5L), covering samples of different sizes from strawberries to watermelons.
The fruit and vegetable respiration meter provides a powerful tool for post harvest scientific research and technological applications through precise sensing technology and intelligent data analysis. This instrument has significant advantages in detection accuracy, ease of operation, and functional scalability, and is driving the transformation of fruit and vegetable preservation technology from empirical judgment to data-driven.
