Drinor Continuous Dewatering Press (CDP) is a unique solution that press water out of biomass. With CDP as an pre-treatment you can increase efficiency of your drying process, and reduce the energy consumption. It is financially gainable, energy saving and a sustainable solution for you and the enviroment.
The technology is a reliable mechanical solution. Biomass such as woodchips and sawdust is transported into a constant cylindrical nip where the water is efficiently removed. This unique solution prevents reabsorption and deliver a constant moisture content down to 30% MC. By using Drinor CDP you will get a tailor made solution that is installed fast and without any process holdups.
Increase the value of your biomass
When industries today process biomass it is often done through several operations. Drying is one of the most expensive steps, where huge amounts of thermal energy is used. Biomass has an unlimited potential to become a solution to replace fossil fuels as an energy source.
Our vision is to increase the utilization of biomass and thereby be part of the change towards a circular bio economy. Our process brings benefits both for the environment and the industry. This is why we created the Drinor Continuous Dewatering Press.
Drinor is an innovative company that provide solutions for a higher utilization of all biomass.
By providing new solutions to the market we want to change the perceptive of biomas potential. We challenge the way biomass is seen and also how to do business within the segment, by providing innovative business models.
Bioenergy is the only option today to become the future on and of switch for energy demand. Biomass has unlimited potential to become the solution to replace fossil fuels as an energy source. Our mission is to be the provider of the solution that make that possible.
Many areas benefit from using Drinor Continuous Dewatering Press
Drinor CDP bring several benefits to the pellet production process. The CDP process removes every ton of water with 95% lower energy consumption than traditional thermal drying systems. When more than half of the water is removed by the press, it is possible to increase the production capacity in combination with the existing drying equipment.
Pellet tests and comparison between dewatered and non-processed sawdust have been performed together with a dedicated science group. They found equal or better pellet quality and performance in comparison to conventional thermal dried biomass.
- Lower energy cost
- Increased production
- Optimized process
With CDP you can dewater residues, sawdust and bark. A dryer biomass increases the energy content and the value. No matter if it is sold for further processing our used within your own energy supply.
- Higher product value
- Lower transport cost
With the CDP a big part of the water is removed from the material and its easier to compress. Approximately 100 kg water is removed from every cubic meter which makes the material lighter. The structure of the material is also change, it is much softer and interlocking in-between the particles makes an high density achievable with low pressure compression.
- Lower transport cost
- Increased transport volume
The CDP can be implemented as an efficient pre-treatment method before biomass is processed into industrial sugars or biogas. The enzymes or other additives will have access to the core of the material and the cracked cell structure will increase the process yield. The water pressed out of the material contains carbohydrates where the level is depending on the chosen process. The water itself can work as an substrate for biogas production.
- Improved process yield
- Efficient pre-treatment
- Easy access for acids and enzymes
There is a clear energy saving potential associated with dryer fuel, a decreased moisture content increases the fuel lower heat value (LHV). It also gives potential positive effect from an increased boiler temperature which will enable a higher power-to-heat ratio. By implementing the CDP and obtaining an dryer biomass the efficiency can be optimized.
- Higher heat value
- Higher power generation
- Optimized efficiency
Research & Technology Centre
Our technology centre in Karlstad , Sweden, is equipped with an pilot CDP that is available for all customers worldwide. For trials and optimization, with an strong focus on more efficient processes and and higher utilization of biomass.
The technology centre is equipped with a pilot of the machine marketed by Drinor. Trials are tailor-made together with our customers to fit their need and to explore the benefit of the CDP process. Extended process control gives our trial facility the flexibility to precisely monitor, easily change parameters and document the process results.
Drinor is co-funded by the Swedish Energy Agency. The Agency is involved in broader international energy research cooperations, which among other things, is about the increased use of renewable energy sources and development of new technologies and systems for energy supply.
Drinor AB develops and provide the market with an innovative mechanical dewatering process, the CDP solution, to facilitate the circular bio economy when utilizing biomass.

Drinor is also a member of the bio-economy cluster Paper Province. For further about how Paper Province transform Sweden into an bio-economy,
Drinor is co-funded by Copolia, who has developed the background technology. For more info regarding Copolia hit the link below.
The region Värmland (Sweden) provides lots of resources, bio material, engineering and process skills and here is also a large existing network and cooperation coordinated by the Paper Province cluster between trade and industry with science knowhow through KAU (Karlstad University).
Drinor was started here as a project to finally find a mechanical solution for dewatering of biomass. The team was constructed with Engineers, Economists and forestry experts to come together around a solution that seems fit for the bioenergy-sector. The project evolved in to Drinor AB, that now are developing the first pilot-machine for industrial use.
