Dryer for grape pomace

Сушилка для виноградной выжимки

LLC "NPK" ENERGOTEK " designs and manufactures dryers for grape pomace (waste in the production of wine, grape juice).   


The most optimal unit for drying grape pomace is a drum dryer . Our company has the ability to design and manufacture any drying drum with  productivity in the range from 0.5 tons per hour to 3 tons per hour. If higher productivity is required, our company is ready to offer modular complexes for drying grape pomace with a capacity of 6 tons per hour to 20 tons per hour.


If the grape pomace is planned to be used after drying as a feed or food additive, then it is necessary to remove the grape seeds before or after drying. The removed grape seeds themselves represent a very valuable raw material for the production of grape oil. Our company also produces dryers for drying grape seeds.


A drying drum for drying grape pomace must be aggregated with a heat generator operating either on gaseous fuel (natural gas, propane-butane mixture), or on liquid (diesel fuel, fuel oil, various synthetic boiler / furnace fuels, water-coal fuel), or on solid ( wood-burning furnaces, coal furnaces, multi-fuel (operating both on pellets, briquettes from wood raw materials, agricultural raw materials, and on wood chips, wood, coal - brown, anthracite, coals of grades D and G), pulverized coal injection installations).


Heat generators operating on natural gas are the easiest to maintain and technologically advanced . They can be fully automated and do not require constant monitoring. The only drawback is the cost of natural gas in Ukraine. The cost of drying is 1.5-3 times higher than when working on solid fuels or liquid (synthetic furnace fuels, pyrolysis products of tires, oils). The most significant savings can be achieved using solid fuel heat generators. Among them, the best price / cost ratio * technological effectiveness is possessed by a pulverized coal-fired heat generator.


And the most economical will be a heat generator operating on briquettes from sunflower husk and also on brown coal (pieces of 20-100mm). However, they have significant disadvantages.


  1. All solid fuel heat generators require a stoker for timely fuel supply and ash removal. When using a wood-fired heat generator, it is necessary to constantly monitor the moisture content of the incoming firewood, otherwise the required  thermal power for the drying process will be impossible. You also need a permanent warehouse for firewood with a week's supply, if you do not have a nearby permanent source of 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 25-37 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. Sometimes it is more expedient to install a heat generator that runs on diesel fuel, or on natural gas and not have unnecessary trouble.  

  2. Also, in addition to the heat generator, for the operation of the drying drum , a smoke exhauster is needed , which ensures the suction of the necessary air for combustion, its passage through the drying drum, cyclone and the evacuation of moisture evaporated from the ores. For each capacity in tons per hour, taking into account the humidity at the inlet and outlet of the drying drum, properties of grape pomace, porosity, etc., 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 grape pomace is the presence of a dust-precipitating cyclone . Grape pomace is a low-dusting material, but nevertheless requires a system for capturing small particles. 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 or ordering 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.

Warranty for grape dryers  - 24 months.

After the end of the warranty - discount service.
