Dryer for medicinal, herbs and plants.

LLC "NPK" ENERGOTEK " designs and manufactures drying drums of various modifications , and drying units of other designs ( aerodynamic (vortex, aerofoil, fluidized bed, with full removal ), belt, conveyor) , for drying medicinal plants and other similar materials, productivity from 100 kg to 5 - 10 tons of raw materials per hour.


Depending on the needs of the customer, as well as the size of medicinal plants (chopped stems for 10-30mm or 50-100mm., Chopped mass - 1-2-10mm., Or whole stem (300-1000mm)), various dryers are used to dry medicinal plants. For chopped mass of medicinal plants, a drying drum of the classic, convective type is better suited. Slightly worse - aerodynamic drying units . And for medicinal plants with a solid stem, a drying drum, like an aerodynamic dryer, is not suitable. In such a case, a belt dryer or a conveyor dryer is best. For more information on belt and conveyor dryers, see the respective sections.


Drum dryer for medicinal plants is a classic drying unit. Please do not confuse it with ABM, which is not very suitable for drying medicinal plants (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 medicinal plants, it is possible to dry raw materials of almost any size from 0.5 mm to pieces of 50-100 mm in size, and with an initial moisture content of 20 to 70%. Final humidity - 2 - 15% (the required percentage of humidity is set at the request of the customer). It must also be understood that the larger the material is cut, the worse the drying will be. All other things being equal - a drying drum of the same size, heat generator power, drying temperature, on coarsely chopped material - the productivity will be 10-25% lower than on finely chopped material.

Our drying plants for drying medicinal plants are mainly aggregated with solid fuel heat generators (wood burning stoves, coal furnaces, wood chips furnaces) with or without a heat exchanger, depending on the customer's requirements. 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 (10-20-30mm, 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 1 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 amount to UAH 60-70 per 1 ton of dry raw materials.

  2. In addition to the heat generator, for the operation of any drying unit - a belt dryer or a drum dryer - a smoke exhauster is required, which provides the suction of the necessary combustion air, 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 unit, 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 ordering a dryer in 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.

The warranty for our drying equipment is 24 months .

After the end of the warranty - discount service.
