Large vegetable specific intelligent cold storage system, fresh wholesale full chain preservation solution
Core parameter comparison table
(Based on the scenario test of daily turnover of 100 tons of vegetables and annual storage of 20000 tons)
| Parameter Category | Core Indicator |
| Effective storage capacity | Single storage capacity 6000-15000m ³ (with a floor height of 5 meters), modular expansion up to 30000m ³, supporting flexible zoning in multiple temperature zones |
| Temperature and humidity control |
precise zoning management: Leafy vegetables: 0 ℃~4 ℃, humidity 90% -95% |
| Pre cooling efficiency | Fresh vegetables drop to target temperature within 3 hours of storage, with a decay rate of<1.5% (industry average 4% -6%) |
| Energy consumption performance | Daily energy consumption per ton of storage is 0.38kWh, equipped with a heat pump waste heat recovery system, saving about 180000 kWh of electricity per year |
Adaptation scenarios: pre cooling and temporary storage of leafy vegetables, long-term storage of root and stem crops, sorting and processing of fruits and vegetables, centralized distribution before cold chain transportation
Analysis of the core concerns of vegetable wholesalers
1. Preservation and Loss Control
• Modified Atmosphere Preservation Technology:
Intelligent regulation of O ₂ and CO ₂ concentrations (such as controlling O ₂ in leafy vegetables at 2% -5% and CO ₂ ≤ 3%), inhibiting respiration and extending shelf life:
The shelf life of spinach has been extended from 3 days to 7 days;
The weight loss rate of broccoli has decreased from 5% to 0.8%.
Dynamic humidity management system:
The warehouse is equipped with ultrasonic humidifiers and dehumidifiers, with humidity fluctuations of less than 3%, to prevent wilting of leafy vegetables or mold growth of roots and stems.
• Dynamic humidity management system:
The warehouse is equipped with ultrasonic humidifiers and dehumidifiers, with humidity fluctuations of less than 3%, to prevent wilting of leafy vegetables or mold growth of roots and stems.
• Layered temperature control design:
The upper low-temperature zone (0-4 ℃) stores leafy vegetables, the middle normal temperature zone (8-12 ℃) stores fruits and melons, and the lower constant temperature zone (4-10 ℃) stores roots and stems, isolated by airtight doors to reduce cross contamination.
2. Improve supply chain efficiency
• Rapid pre cooling system: When entering the warehouse, a "forced convection pre cooling table" is used to lower the temperature of 20 ℃ vegetables to the set temperature within 20 minutes to prevent thermal accumulation and decay.
• Intelligent warehouse layout: equipped with RFID shelf management system, supporting storage by variety, origin, and maturity classification, improving picking efficiency by 35%.
• Seamless connection of cold chain: The warehouse is directly connected to a low-temperature platform (temperature 0-5 ℃), and there is no need for secondary heating when connecting refrigerated trucks, with a temperature difference of less than 2 ℃ throughout the entire process.
frequently asked questions
Q1: How to quickly adjust storage parameters based on vegetable types?
A: One click switch between preset scenarios such as "leafy vegetable mode" and "root and stem mode" through the touch screen interface, or customize temperature and humidity curves.
Q2: How can cold storage prevent condensation on the ground from causing decay?
A: Moisture proof aluminum foil and diversion channels are laid on the ground inside the warehouse, and a floor heating system is equipped to maintain the surface temperature 1 ℃ above the dew point and prevent water accumulation.
Q3: How to avoid temperature fluctuations in the warehouse after large-scale procurement?
A: Configure a buffer pre cooling chamber (capacity 500m ³) to cool vegetables in batches before transferring them to the main warehouse, reducing the impact of heat load inside the warehouse.
The three core pain points of loss control, sorting efficiency, and compliant operation from the field to the terminal are optimized for full process preservation through dynamic air conditioning technology, multi-layer temperature control design, and intelligent warehouse management. Assist wholesalers in reducing losses, improving turnover efficiency, and enhancing market competitiveness through data-driven management.
