  • Patent number: 10773417
    Abstract: The present invention provides a method for processing a molded tray based on bamboo-wood mixed shavings, comprising: extracting, crushing, mixing, drying, separating by wind separation, heat balance treatment, mixing glue, paving and hot pressing, cooling and grinding, inspecting and warehousing. In the invention, the industrial trays are manufactured by mixed bamboo and wood materials. The bamboo materials do not include bamboo peels and other impurities. The use of bamboo materials can improve the quality of trays from raw materials and reduce the moisture content of the trays. In addition, the brittleness of bamboo materials can improve the hardness of trays. The combined bamboo materials and wood materials can increase the toughness of the product and reduce the cost; furthermore, each link in the production process is elaborately designed and adjusted in the invention. The industrial trays made by the processing method of the present invention have increased the weight supporting capacity by at least 1.
