Abstract: A seed crystal coating machine dedicated for 800-1000 mm industrial stainless steel or ceramic tubular membrane support was developed. The machine adopt a coating method of spray and smear, seed crystal suspension was first spayed onto the rotating tubular support and then smeared evenly to form a thin film by inflated silicone rubber balloon. Combined with automatic control technology, the machine provided a solution for automatic seed crystal coating in process of zeolite membranes mass production. Main structure and working principle was introduced and the key factors affecting coating performance such as balloon hardness, balloon structure, balloon inflation pressure and moist state of seed crystal has been tested and analyzed. Production experiment of NaA zeolite sieve membrane with prototype has been conducted and the performance of products has been tested with 90% industrial alcohol at temperature of 75℃. Result showed the design was feasible and reliable, prototype coating speed was 30 products per hour and yield was above 98%; permeation flux of produced sieve membrane was 4-5.5 kg·m^-2·h^-1, water ratio of penetrating fluid was 99.2%-99.8%.
