| Abstract An apparatus for determining one or more optimal operating parameters for debarking wood is provided. The apparatus has a scraper and an actuator configured to adjust the position of the scraper toward a sample portion of the wood to scrape a surface of the sample portion of the wood with a scraping force. The apparatus also has a force sensor operatively associated with the scraper for detecting the scraping force. A light source impinges light on a scraped surface of the sample portion. A light detector detects a light image defined by light from the light source reflected by the scraped surface. A controller is operatively associated with the force sensor and the light detector. The controller has processing means to determine the one or more optimal operating parameters based on signals relating to the scraping force and signals relating to the light image. The one or more optimal operating parameters are relevant to debarking wood proximal to the sample portion. | ||||||

| The present invention concerns a method and an apparatus for defrosting frozen wood prior to debarking. The defrosting method of logs of the invention is based on bringing heat zone-specifically to logs in transfer motion on a conveyor according to their heat receiving capacity immediately from the moment of starting of the defrosting, and at the end of the defrosting process, the heat volume per time unit, supplied at a higher temperature, is only a part of the heat volume of the starting phase of the defrosting process. For instance, it is possible to spray water on the wood to be defrosted so that the row interval of the showers in the initial part of the piping is a fraction of the row interval in the tail end of the piping. In the tail end of the defrosting conveyor steam can also be supplied. |

| Dans un prodédé et une unité mobile pour l'écorçage et/ou l'ébranchage et le dégrossissage en continu, un tronçon de bois effectue un déplacement linéaire grâce à une unité d'avancement (6) comprenant deux cylindres d'avancement en relation l'un avec l'autre, mobiles en direction d'un dégrossisseur (4). Avant l'étape des cylindres d'avancement, une première étape consiste à retirer les branches à l'aide d'une unité d'ébranchage (7) comprenant au moins deux organes à lames, mobiles l'un par rapport à l'autre selon un plan s'étendant essentiellement transversalement par rapport à la direction de déplacement longitudinal du tronçon de bois, lesdits organes étant pressés contre la surface périphérique dudit tronçon. Durant le mouvement d'avance linéaire du tronçon de bois, les branches sont cisaillées ou coupées. Lors de l'écorçage, l'unité d'avancement (6) est suivie par une unité d'écorçage rotatif (5) entourant le tronçon de bois et comprenant un certain nombre d'organes d'écorçage, munis d'éléments conçus pour effectuer la coupe ou pour venir frotter contre la surface périphérique du tronçon de bois. Grâce à la force centrifuge s'exerçant durant un mouvement rotatif par rapport à un plan différent de la direction d'avance du tronçon de bois, lesdits éléments sont pressés contre la surface périphérique du tronçon de bois et, par une opération de coupe, retirent une couche d'écorce entourant le tronçon de bois. | ||||||

| A method and system for detecting and controlling the quality of debarking at the surface of a wooden log provide information on main parameters related to the debarking quality of the log surface, including fiber loss and residual bark. The debarking quality detecting method and system involve measurement of three-dimensional profile of at least a portion of the log surface to generate corresponding profile image data, which is processed to generate data indicative of the texture of the log surface. The texture data is then analyzed to generate resulting data on the debarking quality parameters. That quality indicative information can be generated on a continuous basis to provide an objective assessment of the quality performance in real-time in view of target productivity, and may then be used to perform optimal adjustments of the debarker operating parameters, either manually by the operator or automatically through feedback control. | ||||||
