Bulk Storage: A High-Capacity, Cost-Effective Solution

Bulk storage is one of the most widely used methods for preserving vegetables in Russia — and for good reason. Its simplicity, reliability, and ability to handle massive volumes have made it a top choice for producers. Potatoes, one of the most in-demand crops worldwide, are especially well-suited for this type of storage.

Key Advantages

• Supports very high storage volumes

• Ensures stable, uniform temperatures across the entire chamber

• Provides effective ventilation and drying

• Requires minimal technological equipment

• Offers fast construction timelines and budget-friendly installation

Bulk storage is ideal for potatoes, onions, and beets — crops essential to markets across India, Africa, and Saudi Arabia.

Bulk Storage Requirements

Bulk vegetable storage must be fully isolated from the external environment and well-insulated from cold air. Inside the facility, crops are stored in designated sections or rooms.
Depending on the type, variety, and purpose of the vegetables, the number of individual storage compartments can be significant. Each room maintains its own microclimate optimized for a specific crop.

How Microclimate Control Works

At the core of any efficient bulk-storage system is the air-preparation chamber.
It typically consists of one structural wall of the storage building and an internal load-bearing wall.

Airflow Process

1. Fresh air enters the facility through intake valves on both sides of the building.

2. It moves into the air-preparation chamber, where temperature and humidity are adjusted.

3. Regulation is achieved using:

   • Recycle valves

   • Humidifiers

   • Heaters

   • Coolers

4. Once conditioned, the air is pushed into perforated pipes by high-pressure fans.

   • Fans may be mounted directly inside the pipes or positioned on the hollow floor of the chamber.

5. The prepared air then flows through air ducts into the vegetable storage area.

Pipes, Floors, and Air Distribution

Perforated pipes can be made of galvanized steel for extended service life, while wooden pipes offer a cost-effective alternative.

To increase usable capacity, many modern storage facilities rely on a slotted floor system, installed above underfloor air ducts. This design:

• Maximizes available storage space

• Improves the distribution of conditioned air

• Enhances equipment accessibility

• Provides efficient ventilation, humidification, and heating of stored produce

Exhaust air is removed through open intake and recycle valves, where it mixes with fresh incoming air to maintain stable conditions.

To prevent condensation build-up, dedicated fans — some equipped with heating elements — are used to maintain continuous air movement.
