Abstract: As a new kind of low energy-consuming and environmental protection equipment, automatic equipment of pulp model snack container has been accepted widely. Main technological parameter of the key process vacuum filter affect the quality of products is studied. This process is optimized by means of "cross regression"bass on productive equipment. The best parameter cooperation had been obtained to be able to make the moulding equipment of paper pulp get that excludes water rate after vacuum filter process by optimization. In debug course, the vacuum degree was set directly at the best value. The other parameters debug again. It can reduce the test frequency in debug course greatly and raise production efficiency.
