Patent CA-2118455-A1 (CA)
Title: Meat trim sorting
Inventor: BROWN GARY
IPC: B07C5/36
Filed: 1994-10-19
Abstract: A sorting system is disclosed for reclaiming lean meat from high-fat meat trimmings. The sorting system includes a meat dicing machine which receives laterally extending whole meat trimmings and which dices such meat trimmings without grinding or extruding, and without disturbing the lateral distribution of the meat. This results in a lateral distribution of meat trimmings, without requiring vibratory distribution which is disfavored in meat processing plants. A wide-belt inspection conveyor is positioned at the downstream end of the meat dicing machine to receive the laterally distributed meat dices. The wide-belt inspection conveyor operates at a greater linear speed than does the meat dicingmachine to longitudinally space the meat dices from each other. An optical inspection and sorting station is positioned at the downstream end of the wide-belt inspection conveyor to differentiate relatively lean meat dices from relatively fatty meat dices and to separate such meat dices from each other.

Filed: 1994-03-15
Abstract: DEVELOPMENT OF A UNIFORM TEMPERATURE GRADIENT IN A BLOCK OF CHEESE     Abstract of the Invention The present invention is directed to a method and apparatus for developing a uniform temperature gradient in a block of cheese.  The apparatus includes a chamber for receiving a cheese block.  The chamber has a uniform cross section and has opposed openings separated by the length of the chamber.  The chamber is surrounded by insulation on the peripheral surface between the openings.  A heat exchange surface is disposed over and closes one of the openings.  A second heat exchange surface is disposed over and closes the other of the openings.  The temperature of the two heat exchange surfaces are different.  When a block of cheese is disposed within the chamber, a temperature gradient can be established in the block of cheese in a relatively short period of time.  Thereafter, the cheese block can be sliced into appropriate sections for determining moisture content as a function of cheese temperature.

Abstract: Sur le marché, il existe une variété d'encens en granules qui se consument en les versant sur un charbon placé dans un encensoir de laiton, de céramique où autres réceptacles résistant ;à la chaleur. Les charbons utilisés sont auto allumant car ils sont enduits de salpêtre. Il s'allume avec une allumette et comme un bâton de fête il pétille quelques instants avant de devenir rouge. Cela est très dangereucx et désagréable, il dégage aussi une fumée toxique. Le charbon est aussi très salissant. Avec le Cérémonial brûleur électrique, le charbon n'est plus nécessaire, il suffit de mettre l'encens sur la plaque chauffante et de mettre le commutateur à "ON". La plaque atteindra sa température maximum qui est pré-ajustée pour une parfaite consommation de l'encens. Le corps cylindrique de métal perforé de toute sa surface, permet une adéquate ventilation permettant donc un refroidissement du corps de l'encensoir et ainsi éviter d'endommager les autres composantes par la chaleur. Le couvercle du cérémonial a la particularité d'avoir une cheminée à son sommet qui permet de brûler sans électricité les encens en bâton en les inserrant le feu vers le bas dans la cheminée.
