Fruit and Vegetable Fresh-Keeping System Equipment

The Fruit and Vegetable Fresh-Keeping System Equipment is an intelligent, multi-functional integrated preservation control device developed to address the critical post-harvest challenges of fruits and vegetables: rapid decay, water loss and wilting, oxidative deterioration, and bacterial growth. Unlike traditional cold storage facilities that rely solely on low temperatures, this system integrates six core technologies: precise temperature and humidity control, dynamic modified atmosphere bacteriostasis, micro-ozone disinfection, negative ion purification, ethylene degradation, and intelligent data management.

By comprehensively intervening in the fruit and vegetable deterioration process from multiple dimensions—temperature, humidity, gas composition, microorganisms, and harmful ripening gases—it effectively slows respiration, inhibits bacterial and mold growth, degrades ethylene, and preserves moisture and nutrients. As core supporting equipment for modern agricultural storage, cold chain logistics, supermarket preservation, and fresh produce processing, it significantly extends shelf life, reduces spoilage rates, and solves long-standing industry pain points including short preservation periods, high decay rates, severe water loss, and substantial storage losses.

Industry Challenges and Limitations of Traditional Methods

After harvesting, fruits and vegetables remain living organisms that continue to respire, consuming sugars, water, and nutrients while releasing ethylene—a natural ripening gas. Combined with mold and bacterial growth, temperature and humidity fluctuations, and poor air quality, this leads to yellowing, softening, dehydration, decay, and off-flavors, causing massive agricultural losses.

Traditional cold storage facilities only provide temperature reduction without humidity or gas composition control. Excessively low temperatures often cause chilling injury and dehydration, resulting in dry skin and degraded texture. Conventional preservation equipment has single functions, unable to degrade ethylene or eliminate mold, leading to limited preservation effectiveness. The Fruit and Vegetable Fresh-Keeping System Equipment creates a customized microenvironment adapted to the physiological characteristics of produce, precisely inhibiting respiration, blocking deterioration triggers, and preserving original color, texture, and nutrients for long-term freshness.

Core Advantages

1. Multi-Dimensional Comprehensive Preservation: Extends Shelf Life and Reduces Spoilage

Breaking through the technical bottleneck of traditional single-temperature preservation, this system adopts a five-in-one integrated preservation model: temperature control + constant humidity + modified atmosphere + bacteriostasis + ethylene removal. It targets all core causes of fruit and vegetable deterioration:

· Precisely inhibits respiration to reduce organic matter consumption and delay senescence

· Continuously degrades ethylene gas to prevent the chain reaction of batch ripening and rotting

· Eliminates mold, yeast, and spoilage bacteria at the source

Compared to traditional cold storage, it extends the preservation period of leafy vegetables and berries by 2-3 times, and melons and fruits by 3-5 times. Overall fresh produce spoilage rates are reduced from 20-30% to less than 5%, significantly minimizing agricultural waste and improving economic benefits.

2. Precise Constant Temperature and Humidity Control: Prevents Chilling Injury and Dehydration

Traditional cold storage suffers from large temperature fluctuations and uncontrolled humidity, leading to chilling injury, frost damage, and rapid water loss that causes wrinkling, weight loss, and reduced market value. The Fruit and Vegetable Fresh-Keeping System Equipment features high-precision sensors and intelligent frequency conversion modules, achieving ±0.5°C temperature accuracy and intelligent humidity balancing. It automatically matches exclusive temperature and humidity parameters for different produce varieties, effectively avoiding stress-induced deterioration from temperature fluctuations and maintaining water vapor balance to preserve plumpness, crispness, and bright color.

3. Dynamic Ethylene Degradation and Air Purification: Eliminates Batch Spoilage and Off-Flavors

Ethylene accumulation in traditional storage accelerates ripening and causes batch rotting. Additionally, odors, mold spores, and airborne bacteria from decaying produce further exacerbate overall deterioration. This system incorporates a dedicated ethylene decomposition module and negative ion purification unit that:

· Continuously adsorbs and decomposes ethylene and VOC odors 24/7

· Purifies enclosed storage air in real time

· Kills airborne mold and spoilage bacteria

It completely solves the common problems of "increasing ripeness, increasing decay, spreading odors, and cross-contamination" in traditional storage, ensuring stable preservation of entire batches without off-flavors or mass deterioration.

4. Intelligent Variety Adaptation: Customized Preservation for All Produce Types

Different fruits and vegetables have vastly different physiological characteristics. Leafy greens, berries, melons, and root vegetables require distinct temperature, humidity, and gas environments. Traditional equipment cannot provide differentiated control, leading to either over-preservation or insufficient preservation.

The Fruit & Vegetable Fresh-Keeping System has built-in exclusive preservation programs for all categories: leafy vegetables, berries, tropical fruits, root vegetables, mushrooms, and melons. Users can switch to dedicated modes with one click, and the system automatically adjusts corresponding temperature, humidity, purification, and ethylene removal conditions. Custom parameter settings are also supported based on harvest maturity, storage duration, and environmental conditions, enabling refined and scientific preservation.

5. Energy-Efficient, Quiet Operation and Intelligent Unattended Maintenance

Adopting frequency conversion energy-saving technology, the system automatically adjusts operating power based on real-time environmental data, entering low-power standby when conditions are stable and increasing power only when necessary. This achieves over 40% comprehensive energy savings compared to traditional cold storage equipment.

Operation is quiet and stable with no violent vibrations or direct airflow that could damage produce skins. The intelligent cloud management system provides 24/7 real-time monitoring of temperature, humidity, gas concentrations, and equipment status, automatically generating preservation data reports. It supports remote viewing, remote control, and fault alarms, enabling unattended operation and significantly reducing labor management costs.

6. Wide Adaptability and Flexible Installation: Suitable for New and Existing Storage Facilities

With modular design and easy installation, no major structural modifications to storage facilities are required. It is directly compatible with:

· New preservation warehouses

· Traditional old cold storage retrofits

· Supermarket display cases

· Fresh produce pre-cooling rooms

· Cold chain transit warehouses

It can be used for large-scale long-term preservation in production bases and processing plants, as well as short-term shelf preservation in small supermarkets, community fresh stores, and fruit stalls. This makes it the optimal supporting system for upgrading traditional cold storage and reducing losses in fresh produce storage.

Primary Application Scenarios

1. Agricultural Production Base Storage

Ideal for centralized pre-cooling, sorting, and storage immediately after harvest. It rapidly removes field heat, inhibits post-harvest respiration, and solves problems of oversupply and short-term decay during peak harvest seasons. By enabling off-peak sales, it helps farmers increase product premiums and reduce post-harvest losses, promoting standardized and industrialized agricultural storage.

2. Supermarkets and New Retail Stores

Supermarkets and fresh produce stores face the highest spoilage rates due to dense display, poor ventilation, and susceptibility to mold and dehydration. The system can be integrated into supermarket display cases and storage rooms, providing real-time air purification, ethylene degradation, and constant temperature and humidity preservation. It effectively extends shelf life, maintains fresh appearance, and significantly reduces daily spoilage losses to improve store profitability.

3. Cold Chain Logistics Transit Storage

During long-distance transportation and transit, enclosed spaces easily accumulate ethylene and grow mold, leading to mid-transit spoilage. Deployed in cold chain transit warehouses, front warehouses, and sorting centers, the system maintains a stable preservation environment throughout the journey, ensuring freshness from farm to table and solving the industry pain point of broken cold chains and high losses.

4. Fruit and Vegetable Processing Plants

Fruit and vegetable deep-processing enterprises require large-scale raw material reserves. Raw material spoilage, water loss, and deterioration during storage negatively impact processing quality and finished product taste. The system stably maintains raw material freshness, locks in nutrients and moisture, avoids raw material waste, improves product quality, and reduces procurement losses for standardized food production.

5. Community Storage and Institutional Canteens

Schools, enterprises, government canteens, and community fresh storage facilities often face problems of accumulated spoilage due to large storage volumes and unstable turnover cycles. The Fruit & Vegetable Fresh-Keeping System enables long-term preservation, ensuring daily ingredients are fresh, safe, and free from deterioration or off-flavors, reducing food waste and ensuring food safety.
