摘要:
A vegetation tray includes a base. The base is formed from a thin wall having a plurality of spaced peaks and valleys. A plurality of apertures are in the base. The apertures enables passage of air for drying vegetation on the tray. A boundary wall extending from the base.
摘要:
A method for the treatment of wood or wood products, in which method moist wood or wood products (1) are first dried by pressing and further by heating so that a desired degree of dryness is reached. In the first stage, the wood or wood products (1) arranged between treating elements (2) are pressed between the treating elements (2) so that liquid is removed from the wood being treated. In the method, as a result of the combined effect of the pressure, the liquid and/or gaseous substance released into the chamber space from the wood material being treated and possibly also air circulation arranged in the treatment chamber, a change of temperature in the treatment chamber from a lower temperature (T1) to a higher temperature (T2) is achieved without supplying additional heat into the chamber.
摘要:
A product tray (3) has a bottom (7) that is improved with respect to heat transmission from a heating plate (8) to the product (9). The bottom (7) is made of a flexible, thin, heat-resistant material. Therefore, it can make a good form fit to the heating plate (8), especially when under load by the product (9), which results in a good thermal contact.
摘要:
Trockenrähmchen (4) für keramische Formlinge (12), insbesondere Dachziegel, mit einer zumindest einen Formling (12) aufnehmenden und zumindest bereichsweise perforierten plattenförmigen Basis (5) sowie auf diese aufgebrachte, den Formling in unterschiedlichen Niveaus abstützenden Aufbauten (9,16,20) sollen so verbessert werden, dass sie bei einfachem Aufbau auch nachträglich an unterschiedliche Dachziegelmodelle anpassbar sind, eine optimale Trocknung gewährleisten und kostengünstig zu erstellen sind. Dazu wird vorgeschlagen, daß der den Formling (12) aufnehmene Bereich der Basis (5) mindestens bereichsweise in enger Teilung mit Lochungen (8) ausgestattet ist, welche vorzugsweise fixiert und entnehmbar gehaltene Schäfte (10) von Stützkörpern (9) aufzunehmen vermögen, deren freien Enden (13) Formlinge abzustützen vermögen.
摘要:
A planking for firing, free from thermal deformation and having a long life; and a method of firing a ceramic molded product by using this planking, which method can prevent the occurrence of distortion of ribs of, and deformation and discoloring of an end surface of, and cracks in, a honeycomb structure. The planking for firing consists mainly of 55-85 % by weight of cordierite and 15-45 % by weight of mullite, and a raw ceramic molded product is placed on such a planking and fired.
摘要:
Installation de séchage et de cuisson dans laquelle les produits traversent le four de séchage (S) et le four de cuisson (C) sur les mêmes wagons (1 ) par le moyen d'une voie unique et continue, sans manutention intermédiaire ; les produits sont empilés sans contact entre eux au moyen de supports céramiques superposés ; la sortie du four de séchage est reliée à lé entrée du four de cuisson par une enceinte (I) étanche à l'air, l'ensemble formant ainsi une enceinte continue et étanche, et la pression des gaz à l'entrée des produits dans le four de cuisson est au moins égale à la pression des gaz à la sortie des produits hors du four de séchage.
