​Drinor demos Continuous Dewatering Press (CDP) for potential customer

In December 2014 Drinor unveiled their innovative dewatering press, since then the focus has been on the commercialization. A contact is established with FPInnovations in Canada. It is an organization that works to support the Canadian forest industry, by help resolving technical obstacles. Now the hope is that Drinor can provide them with a possible latest solution.

FPInnovations Vice President, Dominik Roser, is on site to oversee Skogforsk and Drinor test drive the different materials which are then taken for analysis.

- We process chips, forest residues and bark. Today we push the machine to see what we can get for moisture level and particle size to see if there is potential for the Canadian forestry. It is hoped that the press fulfills a purpose so that they are interested in buying a press, explains Alexander Thelander, Drinors marketing director.

Facilitates drying and transport

The advantages gained by pressing the fibers are energy savings and make them easier to transport. Materials pressed becomes lighter, more malleable and takes up less space when the fibers contain less water. You can use one railway wagon in stead of three when the softened chips are shipped. Dewatering is expected to reduce energy consumption in the Swedish sawmills and bioenergy production corresponding to the heating of 25,000 houses. There are several different advantages using the dewatering process.

The Canadian forest industry wants to know more precisely what the potential it has for them. During the two days Drinor are visited by the FPI and Skogforsk they made several tests of different materials. Furthermore done some special tests such as the press of salt water.

- In Canada, the problem is to fleet the bark, so we have made salt water that we have soaked the bark in order to see how the press works there, says Thelander.

Results at the end of the year

The materials used in the test run is from Swedish forests, but corresponds to what one might find in Canada. The chips, logging residue and bark tested in the machine will be brought to the Skogforsk in Uppsala, hired by FPI to analyze the samples. Where it will be placed in a drying cabinet.

- The standard is that it dries in 48 hours, says Johanna Enström that are the representative on site from Skogforsk. She estimates that the results are expected to be complete by year-end. Alexander Thelander, however, is optimistic.

- I believe in this. They turn to us for the latest technology and it is great acknowledgement for us.
