Due to the short storage time of the pulp, it can’t withstand long-distance transport. We have designed and developed pulp dry system to solve these problem. After the flash drying, the dry pulp block can be stored for a long time, which solves the problem that the wet pulp sheet only can be stored for short time or the pulp would be deteriorated over a period of time. And the dry pulp block can be transported over a long distance, thereby expanding the sales area of the products. Compared with the conventional pulp machine, the flash drying system has less damage to the fiber during the drying process, and the physical strength of the produced pulp is high. In addition to the application of traditional wood pulp and other virgin pulp fibers, it is more suitable for the drying of waste paper pulp, of which fiber strength is low; after the pulp is pressed into a pulp block, the unit volume density is high. The transport cost is lower than the cost of pulp sheet produced by traditional pulp machine.
