Machines and equipment for processing biomass, agro material, agricultural
commodities, cereals, hops, etc.
Our company deals with the design, production, and sale of technological equipment to process
biomass, agro material, wood waste, etc. Our company also designs and produces machines and
equipment to prepare raw materials designated for further processing such as drying, granulation-
pellets making, and briquetting. We produce and deliver belt and drum dryers of wood sawdust,
wood chips, biomass, cereals, hops, hemp, plastic pulp for processing plastic waste, and other
types of operation requiring drying of loose raw material. Another related production program of our
company is production and delivery of augers, transport fans, material dispensers, cyclone
separators of material. We participate in delivering small and large capacity pelleting and
briquetting lines in cooperation with domestic and foreign partners. Our company is situated in our
own administrative and production facility in which are these types of technological equipment
designed, produced, and then shipped to customers. Technological equipment delivered by our
company is produced by our employees and made of domestic and European material and
components of high quality.

Drum dryer SPB30 AGRO
The single-chamber cylinder system is designed to dry mainly vegetable origin material and dry
up to 248 °F (120 °C). The material is poured into the cylinder by rotating the cylinder and moved by
sliding vanes along the entire length of the cylinder. Drying air from the boiler is supplied to the
drying cylinder using transport ventilators. Hot air is supplied by ventilators which are parts of the
boiler and are regulated by the temperature and volume requirements for each zone separately
through the central pipe. The temperature can be set separately for each zone. Excess air is then
extracted from the cylinder by the exhaust ventilator to the centrifugal separator. The system is
designed for drying material with input moisture of up to 90 % and a size of up to 1.97 in (50 mm) to
output moisture of up to 0 %. It is possible to dry commodities such as alfalfa, hops, hemp, forage
stalks, corn, and other cereals. With the modification of the boiler, the dryer is also suitable for
drying wood chips.

Control system and safety of equipment
The set of devices is equipped with safety components, for instance, a safety thermostat of output
temperature, a temperature sensor in the drum, the temperature sensor of fuel feeder, a sensor of
cover closure of the fuel hopper, temperature sensors in boiler chambers, and chimney flap for
leading heat out of the system. The set of devices is connected to a pressure water supply if material
burns in the drum. The drying drum is equipped with a safety thermostat that switches off the boiler
and ventilator if the temperature is exceeded, closes the heat intake into the system, and the
extinguishing process is started with the help of a servo valve and pressure water in the case of
burning. The whole system is controlled by a touch panel where is clearly and graphically displayed
the technology and a state of all components during drying with needed data. In the case of a defect,
the operators are visually warned by red light and acoustic siren. Possible defects are then also
described on display.
