Process of Pulp Molding Production Line
Pulp molded products are new packaging materials that have been rapidly developed in recent years and are excellent substitutes for wood. Pulp molded products adopt raw material beating - ingredients - compression molding - drying - shaping manufacturing process. Since a large amount of moisture (about 55-60%) remains on the workpiece after the molding, the moisture content of the final product is 12-14%, so the moisture of the workpiece is removed during the drying process of the workpiece. This part of the water is completely removed by the absorption of heat into water vapor. Due to the phase change in the drying process, the energy consumption is very large, and the pulp molded products are processed into high energy consumption products. For this reason, it is necessary to perform thermal analysis on the energy conversion process of the drying. Because the analysis can improve the design and processing of the drying equipment and improve the energy utilization rate, it has important guiding significance for reducing the production cost of the pulp molding products industry.
Categories of Pulp Molding Production Line
Pulp molding production lines can be divided into two categories: industrial packaging pulp molding production lines, food packaging pulp molding production lines. The industrial packaging pulp molding production line can produce various electronic components, hardware tools, electronic products, red wine, etc. The food packaging pulp molding production line is mainly used for the production of eggs, fruits and other packaging, in recent years, the use pulp molding production lines for the production of lunch boxes from raw pulp or bagasse as raw materials are also emerging, and are gradually replacing plastic lunch boxes.
