Dryer machine for straw

      ENERGOTEK LLC designs and manufactures drying drums of various modifications, and drying units of other designs (aerodynamic (vortex, aero-fountain, fluidized bed, with full removal), belt, conveyor), for drying straw and other similar materials, performance from 500 kg to 10 tons per hour.
Depending on the needs of the customer, as well as the size of the straw (chopped into 10-30mm or 50-100mm or a whole stem (300-1000mm)), various dryers are used to dry the straw. For chopped straw, a drying drum of a classical, convective type is better suited. A little worse - aerodynamic drying units. And for straw with a whole stem, a drying drum, like an aerodynamic dryer, is not suitable. In this case, it is best - a belt dryer or conveyor dryer. For more information on belt and conveyor dryers, see the relevant sections.
      A drum dryer for straw is a classic dryer. Please do not confuse with an AVM, which is not very suitable for drying straw (since it is less economical (more energy intensive) than convection-type drying units). The main advantage of convection-type drying units that we produce is versatility. In a drum dryer for straw, it is possible to dry raw materials of almost any size from 0.5 mm to pieces with a size of 50-100 mm., And with an initial moisture content of 20 to 70%. The final humidity is 8 - 15% (the desired percentage of humidity is set at the request of the customer). You must also understand that the larger the chopped straw, the worse the drying. Ceteris paribus - the same size drum, heat generator capacity, drying temperature, on coarsely chopped straw the productivity will be 10-25% lower than on finely chopped straw.
      Our drying drums for drying straw are mainly aggregated with heat generators operating on solid fuel (wood fire chambers, coal fire chambers, wood chippers). It is also possible to use heat generators on gas or liquid fuel at the request of the customer.

      The most easy to maintain and economical are heat generators operating on wood / coarsely crushed chips. They are not subject to automation, and require constant monitoring - the presence of a stoker is mandatory. On such heat generators, the lowest cost of drying is obtained — and this is the main advantage of a wood-based heat generator. If you are a supporter of full automation of production, then a heat generator on finely chopped wood chips (10-20-30mm, not more) is more suitable for you. True automation of the process does not completely remove 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 heat generator on wood or a heat generator on wood chips, it is necessary to constantly control the humidity of the incoming firewood, wood chips, since otherwise it will be impossible to achieve the necessary heat output for the drying process. A permanent large warehouse for firewood and a site for the preparation of firewood (unloading, sawing, sorting) are also needed. 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.
       Contrary to established prejudices, rumors, the words of pseudo-experts, it is drying in a classic drying drum for 1 pass with a decrease in moisture, for example, from 20-30 to 8-10%, which 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 energy per 1 ton of dry product than the others. Estimated energy savings compared to other types of drying units common in Ukraine will be 60-70 UAH per 1 ton of dry raw materials.
     In addition to the heat generator, for the operation of the drying drum, a smoke exhaust is required, which ensures 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 inlet and outlet of the drying drum, a smoke exhauster with the necessary parameters is specially calculated, designed and produced.
       The third necessary element for the proper conduct of the drying process of materials is the presence of a dust precipitating cyclone. The parameters of the cyclone depend on the performance of the dryer drum, the amount of moisture removed from the material, such as a heat generator. Therefore, in each case, depending on the configuration, we select cyclones individually.

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

The price is only for a tumble dryer of minimum performance. The price does not include heat generator, cyclone, smoke exhaust.
