    Abstract: Wood chips are fed into a sheath containing two parallel screws that mesh with each other, their respective threads having, at least an upstream series of segments and a downstream series of segments, each of which comprises a drive upstream zone in which the chips are driven downstream and a braking downstream zone through which the chips are forced, the chips thus being driven through the sheath while being braked in the braking zones and while being transformed into fibers. The transit time for which the chips remain in the sheath lies in the range 1.5 s to 80 s, and provision is made for the pressure to be at least substantially equal to 90 bars upstream from the braking zone of the upstream series, so that a temperature lying in the range 120° to 150° C. is reached inside the sheath (10) without supplying external heat.

    Abstract: A method to produce on a commercial scale, high aspect ratio cellulose nanofilaments (CNF) from natural lignocellulosic fibers comprises a multi-pass high consistency refining (HCR) of chemical or mechanical fibers using combinations of refining intensity and specific energy. The CNF produced represents a mixture of fine filaments with widths in the submicron and lengths from tens of micrometers to few millimeters. The product has a population of free filaments and filaments bound to the fiber core from which they were produced. The proportion of free and bound filaments is governed in large part by total specific energy applied to the pulp in the refiner, and differs from other cellulose fibrillar materials by their higher aspect ratio and the preserved degree of polymerization (DP) of cellulose, and are excellent additives for the reinforcement of paper, tissue, paperboard and the like. They display exceptional strengthening power for never-dried paper webs.

  • Patent number: 7954734
    Abstract: Cellulosic biomass is reduced to a micropowder with particles having average diameters below 5-10 micrometers with a significant fraction of the particles have diameters below 1 micrometer. Biomass (e.g., wood, agricultural waste or other plant materials) is first processed into pieces having a maximum diameter of about 10 mm. This is then dried to reduce its water content to no more than about 15% by weight and introduced into a disruptor which reduces the particle size to about 1 mm. Next the biomass is processed with a disc mill where edges of rotating discs travel along a groove pressing and squeezing the biomass, thereby breaking the biomass pieces into smaller and smaller particles. The resulting micropowder is extremely susceptible to enzymatic or chemical hydrolysis into constituent sugars. In addition, the micropowder can be suspended in an air stream and burned directly to provide heat to boilers and similar devices.

    Abstract: An improved brush cutter having an upper feed control member with stop, forward, neutral, and reverse positions also has a lower feed stop member with selectable sensitivity. Another aspect of the invention is to predict the feed roller shutoff point according to the rate of engine deceleration. According to another aspect, when the feed rollers stop feeding material into the cutters, to overcome drag on the cutters, a controller stops the feed rollers and then reverses them for a short time, and then reverses the rollers again if the problem is still present. To prevent jamming, a pressure switch senses when oil in a hydraulic motor system for rotating the feed rollers is too high and the controller momentarily reverses the feed rollers and then causes them to go forward, a cycle which can occur several times until the feed rollers are no longer stalled.

    Abstract: A process for producing water-absorbing polymeric particles comprises the steps of i) drying a hydrogel to produce a dried hydrogel, ii) separating incompletely dried polymeric particles from the dried hydrogel, and iii) drying the separated-off incompletely dried polymeric particles, wherein the separated incompletely dried polymeric particles are comminuted before said drying iii).

  • Patent number: 7654479
    Abstract: An improved brush cutter having an upper feed control member with stop, forward, neutral, and reverse positions also has a lower feed stop member with selectable sensitivity. Another aspect of the invention is to predict the feed roller shutoff point according to the rate of engine deceleration. According to another aspect, when the feed rollers stop feeding material into the cutters, to overcome drag on the cutters, a controller stops the feed rollers and then reverses them for a short time, and then reverses the rollers again if the problem is still present. To prevent jamming, a pressure switch senses when oil in a hydraulic motor system for rotating the feed rollers is too high and the controller momentarily reverses the feed rollers and then causes them to go forward, a cycle which can occur several times until the feed rollers are no longer stalled.

  • Publication number: 20100019073
    Abstract: True zero-clearance cutting on a commercial scale is provided via a cutting area including a sacrifice material that is relatively softer than the cutter. One example is a cutting system which is capable of cutting a material such as, for example, tape or paper, into a fiber or powder. The cutting system includes a cutting blade, typically a rotary cutter, and a sacrificial plate or round bar contacting the cutting blade. The contacting portion has a zero clearance during the cutting operation. A metering mechanism is also provided which is capable of metering the material at a predetermined rate to the cutting blade. A mechanism is also provided for incrementally moving the sacrificial blade towards the cutting blade to ensure that the zero clearance is maintained between the cutting blade and the sacrificial plate, even when the sacrificial plate begins to wear down due to usage.

  • Publication number: 20090302140
    Abstract: A refiner plate assembly and method includes an annular arrangement of adapter subplates that mount to a refiner disk of a disk refiner using a conventional mounting technique, such as bolted in a standard pattern associated with the particular disk refiner. The adapter subplate arrangement remains mounted to the disk and provides a universal mounting surface for an annular arrangement of individual removable refiner segments. A steam and/or accept evacuation channel is provided in this assembly via filter passages at a radially intermediate location in one or more refiner segments which communicate with a recess or channel in one or more associated adapter subplates that direct the steam and/or accepts through outlet ports in the outer rim of the adapter subplate(s). Refining efficiency is provided in a universal refiner plate assembly by eliminating steam volume and already refined pulp from outer portions of the refining zone.

  • Publication number: 20090224086
    Abstract: Cellulosic biomass is reduced to a micropowder with particles having average diameters below 5-10 micrometers with a significant fraction of the particles have diameters below 1 micrometer. Biomass (e.g., wood, agricultural waste or other plant materials) is first processed into pieces having a maximum diameter of about 10 mm. This is then dried to reduce its water content to no more than about 15% by weight and introduced into a disruptor which reduces the particle size to about 1 mm. Next the biomass is processed with a disc mill where edges of rotating discs travel along a groove pressing and squeezing the biomass, thereby breaking the biomass pieces into smaller and smaller particles. The resulting micropowder is extremely susceptible to enzymatic or chemical hydrolysis into constituent sugars. In addition, the micropowder can be suspended in an air stream and burned directly to provide heat to boilers and similar devices.

  • Patent number: 7585665
    Abstract: The present invention is directed to provide an apparatus which is capable of continuously and effectively shattering wastes including organic substances and even such wastes as including fat or other doggy substances suspended in a water, without obstructing an operation of the apparatus. The apparatus comprises a cylindrical vertical housing having annular passages partitioned by adjacent two or more substantially concentric cylindrical walls, a water injection device which produces a pressurized water flow so as to supply high-speed water flows tangentially into the annular passages, and a nozzle which is disposed in any one of the cylindrical walls so as to supply a slurry including organic substance particulates into the high-speed water flows and thus ultrafinely shatters the organic granular substances into particulates having the size of a few micrometers by cavitation effect and/or shearing effect produced in the high-speed water flows.
