Sunflower husk dryer

Сушилка для лузги подсолнечника

NPK ENERGOTEK LLC designs and manufactures drying drums  various modifications, and, drying units of other designs (aerodynamic (vortex, aerial, fluidized bed, with complete removal),  for drying sunflower husk and other similar materials, with a capacity of 500 kg to 10 tons. per hour for dry product.

Sunflower husk is obtained by cleaning and breaking sunflower seeds. In this technological operation, the sunflower seeds going for cleaning, as a rule, are already dry with a moisture content of 6-10%. And therefore, in most cases it is not required to dry sunflower husks.
However, there are situations when sunflower husks are forced to be stored outside and get wet from precipitation (even if it is under a canopy), or
  during transportation - very often it gets wet, as well as during loading and unloading operations.

In such cases, the husk can gain moisture up to 15-30% and become unsuitable for further use and processing. To solve this problem, sunflower husks must be dried. Drying in a tumble dryer is the most versatile solution. Aerodynamic drying is also possible, but it already has some limitations and disadvantages in comparison with a drum dryer for sunflower husks.


Drum dryer for sunflower husk is a classic drying unit. Please do not confuse it with ABM, which is not very suitable for drying sunflower husks (since it is less economical (more energy intensive) than convection-type drying units). The main advantage of the convection-type drying units that we produce is their versatility . In a drum dryer for sunflower husk, it is possible to dry raw materials of almost any size from 0.5 mm to pieces of 5-10 mm in size, and with an initial moisture content of 15 to 50%. Final humidity - 8 - 15% (the required percentage of humidity is set at the request of the customer).

Our drying drums for drying sunflower husk are mainly aggregated with solid fuel heat generators (wood burning stoves, coal furnaces, wood chips furnaces). It is also possible to use heat generators running on gas or liquid fuel at the request of the customer.

The most easy-to-maintain and economical heat generators are firewood / coarse chips. They are not subject to automation, and require constant monitoring - the presence of a stoker is a must. On such heat generators the lowest cost of drying is obtained - and this is the main advantage of a wood-fired heat generator. If you are a supporter of full automation of production, then a heat generator on finely chopped chips (10-20-30 mm, no more) is more suitable for you. True, the automation of the process does not lead to the complete removal of people from the fuel supply process. All the same, an apparatchik is required who will monitor the operation of the fuel supply systems and remove ash. But at the same time, automatic fuel supply is very expensive for many customers.


When using a wood-fired heat generator or a wood chip heat generator, it is necessary to constantly monitor the moisture content of the incoming firewood, chips, otherwise the required  thermal power for the drying process will be impossible. It also requires a permanent large warehouse for firewood and a firewood preparation area (unloading, sawing, sorting). For example, for a heat generator with a capacity of 1-1.5 MW, the required amount of firewood is 25-38 cubic meters per day, which is equivalent to one truck. Thus, it turns out that, depending on the wishes and needs of the customer, the type of heat generator used is not always obvious.  


  1. Contrary to the established prejudices, rumors, according to pseudo-specialists, it is drying in a classic drying drum in 1 pass with a decrease in moisture, for example, from 20-30 to 8-10%, that is the most economical. Compared to aerodynamic dryers of both drum type (AVM-0.65, AVM-1.5) and tubular (Chinese coils), a standard drum consumes significantly less electricity per 1 ton of dry product than the others. Estimated energy savings in comparison with other types of drying units common in Ukraine will be 50-60 UAH. for 1 ton of dry husk.

  2. In addition to the heat generator, for the operation of the drying drum, a smoke exhauster is required, which ensures the suction of the necessary air for combustion, its passage through the drying drum, cyclone and the evacuation of evaporated moisture. For each capacity in tons per hour, taking into account the moisture content of the material at the entrance and exit from the drying drum, a smoke exhauster is specially calculated, designed and manufactured with the required parameters.

  3. The third necessary element for the correct management of the drying process of materials is the presence of a dust-precipitating cyclone . The cyclone parameters depend on the performance of the drying drum, the amount of moisture removed from the material, the type of heat generator. Therefore, in each individual case, depending on the configuration, we select the cyclones individually.

When buying equipment from our company  we provide all the necessary documents - a data sheet, an operation manual, installation and aggregation schemes with feeding and unloading material. We also provide any feasible advisory assistance in the preparation of project documentation for coordination with government agencies.

Dryers are guaranteed for 24 months . After the end of the warranty - discount service.
