We were approached by a customer who planned to store up to 1,600 tons of onions for a long period of time. The main task was to build a system that would allow the product to be stored in bulk with minimal losses, stable quality, and the ability to flexibly control the microclimate in the storage facility.
Our task was to design, manufacture, and install turnkey equipment, as well as to ensure convenient control of all systems.
Initial conditions and tasks
Before launching the facility, we received the following requirements from the client:
- storage of onions in bulk in a single storage facility with a capacity of up to 1,600 tons;
- ensuring controlled air supply throughout the entire thickness of the pile, without “dead zones”;
- the ability to operate in different modes depending on the condition of the product and external conditions;
- maintaining a stable microclimate to reduce shrinkage, prevent rotting and sprouting;
- convenient system control, preferably with remote access and recording of key parameters.
The customer needed a solution that would combine active ventilation, cooling and automated control into a single complex.
Implemented solution
We have developed and implemented a set of engineering solutions tailored specifically to this facility.
1. Active ventilation system
An active ventilation system based on direct-action pressure walls was installed for the onion storage facility, using metal air ducts designed for bulk storage.
What this gives the customer:
- even distribution of air throughout the entire volume of the pile;
- the ability to control the intensity of ventilation depending on the stage of storage;
- reduced risk of local overheating or the formation of pockets of spoilage.
2. Cooling system
We selected and installed a cooling system that works in conjunction with active ventilation and allows:
maintain optimal temperature conditions for long-term onion storage;
respond flexibly to changes in external conditions (temperature, humidity);
ensure stable parameters throughout the season.
The system configuration was selected taking into account the storage volume, loading modes, and product quality requirements.
3. Automated control system
We have implemented a separate control system based on our own software development. It includes:
- a control panel with an intuitive interface;
- the ability to remotely monitor key parameters (temperature, ventilation operation, equipment modes);
data collection and storage for further analysis (history of - modes, events, setting changes);
- flexible configuration of operating algorithms for specific customer tasks.
Result for the customer
After the onion storage facility was launched, the customer received:
- a complete onion storage complex with a capacity of 1,600 tons, ready for operation;
- stable microclimate control, which minimizes product losses;
- the ability to quickly change operating modes depending on the condition of the onions and the season;a simple and intuitive tool for managing the facility, including remote access;
- a technical solution that can be scaled or adapted to other vegetable storage facilities.
