Storage of potatoes

«INCOOLS» company specializes in the design of storage facilities for potatoes on a turnkey basis. Each project is developed based on custom criteria of the Customer. We take into account the climate, the location of the future storage, specific aspects of potatoes cultivation, etc. We use the equipment only by proven brands that are favored by the leading agricultural companies in the world.

TECHNOLOGY OF POTATOES STORAGE

Nowadays, the potato yield in most cases is stored in a storage facility in two main ways: in bulk and in containers of different designs / capacity.

Bulk – potatoes are placed in bulk throughout the storage facility, the volume varies from 500 to 3000 tons or more. Please note, that storage facilities for potatoes with bulk storage method allow to use the entire area of the warehouse as efficiently as possible, the ventilation system ensures uniform air ventilation throughout the product, thereby minimizing yield losses. Bulk method, in turn, is divided into:

storage with semicircular channels;
storage with a slotted floor or underground channels.

The disadvantage of the bulk storage method is the inability to separately store different varieties and different fractions of potatoes or onions.

Container – storage facilities for potatoes of this type allow to separate potatoes of different varieties and fractions easily. Container method, in turn, is divided into:

storage with air mixing units
storage with dryer wall of «Reverse Action»
storage with pressure dryer wall
storage with a wall with pillows

The disadvantage of container storage is that it fails to make the most of the usable storage area, compared with bulk storage.

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.

Vegetable storage facilities

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.

Vegetable storage facilities

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.

Vegetable storage facilities

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.
