Storage of onion

«INCOOLS» designs storage facilities for onion with adjustable gaseous media and different capacities. The incontestable advantage of the «INCOOLS» vegetable storage facilities - we equip storage facilities for onion with a remote monitoring system.

TECHNOLOGY OF ONION AND GARLIC STORAGE

After harvesting, onions are subjected to drying within 1-2 weeks, the next stage - cleaning and sorting. Storage in the refrigerating chamber requires humidity monitoring, the optimal – 80%.

Products are stored:

in bulk – onions are placed in a layer up to 3.5 - 4.5m with active ventilation.
in boxes – root vegetables are placed in boxes with a capacity of 1000-1100 kg. The containers are placed in a specific sequence in accordance with the established storage system in order to ensure effective ventilation of onions inside the container.

EQUIPMENT USED

Vegetable storage facilities

Refrigeration equipment

Refrigeration equipment is necessary for quick and effective cooling of products - this allows you storing vegetables for a long time and without significant losses. We use refrigeration equipment integrated into the ventilation system: special heat exchange equipment for vegetable storage facilities from leading foreign manufacturers.

Longitudinal ventilation system for potatoes storage

Its unique features is that the system uses outside air and supplies it to the storage facility. In most cases we use Dutch equipment. The main tasks of the ventilation system are: drying, cooling and heating products, removing CO2.

Vegetable storage facilities

Pressure drying wall

The storage system allows forcing air through the products. Under high pressure, air is supplied through a pallet hole in the container, the lower part of which is closed by plugs. Given system allows quick drying and coolling the vegetables inside the container. Advantages of the technology: the intensity of ventilation is regulated, effective cooling of products, less energy consumption, the ability to separately store products of different grades.

Dryer wall of «Reverse Action»

A zone of rarefied air (negative pressure) is created between the side walls of the containers, this allows the air flow to quickly pass through the product, drying and cooling simultaneously. Advantages of the technology: all containers are cooled evenly, the ability to store products of different varieties, effective ventilation of vegetables, minimal energy consumption.

Vegetable storage facilities

Humidification system

To avoid shrinkage of the products, vegetable storage facilities are equipped with additional air humidification equipment. This allows to preserve the high quality of the vegetable. Each type of vegetable requires the selection of customized equipment to avoid the appearance of water drops in the atmosphere of the storage facility and on vegetables.

Storage management system

Specially developed software allows monitoring the work of the entire vegetable storage facility. The system makes it possible to regulate the atmosphere in the storage facility depending on external and internal factors. The program notifies of changes, errors, critical temperatures and allows to change the parameters of storage facility remotely.
