Abstract
A method and a device to be used in the process of manufacturing plates, such as fiberboards or the like boards, where the raw material in form of bio-mass particles, such as wood fibers or the like, applied with a thermosetting binder is spread onto a forming belt to form a mat, and where said mat by means of a hot press is compressed into the desired thickness of the finished plate and the thermosetting binder is hardened. According to the inventing a system and corresponding method for manufacturing biomass-based products is provided that has enhanced efficiency due to the application of ultra sound.
Claims28
A system for enhancing manufacturing biomass-based products, the system comprising:
- a dryer (101) for receiving an airborne flow of fibres or biomass particles (105),
- a binder applicator (102;
- 401) for applying a binder solution to an airborne flow of fibres (105) received from said dryer (101),
- a forming station (103) for producing a fibre or biomass mat (110) from an airborne flow of fibres being applied with said binder solution and being received from said binder applicator (102, 401),
- characterized in that said system further comprises one or more of:
- at least one ultrasound device (301) adapted, during use, to apply ultrasound to the airborne flow of fibres (105) after said binder solution has been applied and before said airborne flow of fibres (105) is processed in said forming station (103),
- at least one ultrasound device (301) adapted, during use, to apply ultrasound to the airborne flow of fibres (105) in said forming station (103) in connection with the production of said fibre or biomass mat (110), and
- at least one ultrasound device (301) adapted, during use, to apply ultrasound to said fibre or biomass mat (110) after it has been produced by said forming station (103).
A method of enhancing manufacturing biomass-based products, the method comprising:
- drying, by a dryer (101), an airborne flow of fibres or biomass particles (105),
- applying a binder solution, by a binder applicator (102;
- 401), to an airborne flow of fibres (105) received from said dryer (101),
- producing, by a forming station (103), a fibre or biomass mat (110) from an airborne flow of fibres being applied with said binder solution and being received from said binder applicator (102, 401),
- characterized in that said method further comprises one or more of:
- applying ultrasound, by at least one ultrasound device (301), to the airborne flow of fibres (105) after said binder solution has been applied and before said airborne flow of fibres (105) is processed in said forming station (103),
- applying ultrasound, by at least one ultrasound device (301), to the airborne flow of fibres (105) in said forming station (103) in connection with the production of said fibre or biomass mat (110), and
- applying ultrasound, by at least one ultrasound device (301), to said fibre or biomass mat (110) after it has been produced by said forming station (103).
