Description
Bulk storage of vegetables (bulk)
Bulk storage of vegetables (bulk) is a common and effective method of storing vegetable products. It is widely used for storing potatoes, onions, carrots, beets and similar vegetable products. With the use of the minimum amount of equipment, it is possible to save a large amount of vegetable products, reducing product mass losses by 15%, losses associated with germination and rotting of products – by 3%.
The principle of bulk storage of vegetables is ventilation, which creates the necessary microclimate in the vegetable storage. The air, the temperature of which is previously adjusted, passes through the thickness of the vegetables, blowing each fruit. This allows you to keep the product in the “immediately after harvesting” state.
Ducts above ground
The dimensions of the ventilation ducts is calculatedby the volume of ventilated air and the air speed in the duct. The length of the ventilation dust is limited to 20-25 m, and this has direct consequences how they will be placed: along or across the storage.
To guarantee efficient air distribution, the ducts must slope downwards. The size of the ducts depends on the size of the boxes and the power of the fans.
Undeground ducts
To ensure a good distribution of the supply air, the ventilation ducts should be gradually narrowed. It is also possible to arrange the beams at different distances from each other. The selected distance depends, among other things, on the width of the wooden or concrete beams.
Grid floor
The dimensions of the vgrid floor is calculated by the volume of ventilated air and the air speed in the duct.
With this system, there is a basement under the entire floor area. The floor itself consists of concrete ventilation grids.The basement floor in this system most often has no slope, and all the distances between the slots are equal.
In principle, two alternatives:
- horizontal mounting with a pressure chamber
- vertical mounting in the corridor
