Specialized cold storage for vegetables is core infrastructure for preserving freshness, extending shelf life, and reducing postharvest losses. Designed around precision temperature control, constant humidity preservation, and energy efficiency, it sets scientific temperature and humidity parameters based on water content, respiration rate, and low‑temperature tolerance of different vegetables, uses properly sized insulation panels, and integrates intelligent monitoring and AI defrosting in compliance with fruit and vegetable refrigeration standards. Widely used in planting bases, wholesale markets, supermarket distribution centers, and processing facilities, it enables zoned, standardized storage of leafy vegetables, root vegetables, cucurbits and solanums, and edible fungi to retain nutrition, texture, and market value, with full customization available for scale, crop types, and turnover cycles.
Its core logic is precise temperature–humidity matching to balance preservation and energy use. Conditions vary sharply by category: leafy vegetables and edible fungi require 0–2°C and 90%–95% high humidity; storage‑tolerant leafy types allow slightly wider ranges. Root vegetables split into low‑temperature (0–1°C, 80%–85%) and medium‑temperature (3–5°C, 70%–75%). Cucurbits and solanums include thermophilic types (8–12°C, 85%–90%) and low‑temperature tolerant types (5–8°C, 80%–85%), all avoiding chilling injury, mold, and dehydration.
Insulation uses certified PU double‑sided color steel sandwich panels: 100 mm for medium‑temperature storage, 150 mm for low‑temperature, 180 mm for ultra‑low‑temperature, with thickness adjusted for climate and size. The system delivers stable temperature and humidity, intelligent remote monitoring, AI defrosting to cut energy use and extend equipment life, independent zoned control, backup power, and full food‑safety compliance. It minimizes postharvest losses, supports long‑term safe storage, and boosts efficiency across the vegetable supply chain.
