Project Background: A large-scale dairy enterprise’s filling workshop was facing serious problems due to the slow opening and closing speed and poor sealing performance of the original ordinary rolling shutter doors:

• Large fluctuations in workshop temperature and humidity, affecting product shelf life

• Mosquitoes and dust entering the workshop, leading to unstable microbial testing pass rates

• High energy consumption caused by frequent door opening and closing

Product Solution: Food-grade PVC high-speed clean rolling shutter door with core configurations:

• Food-grade antibacterial curtain + silicone sealing strip, resistant to daily high-temperature disinfection

• High-speed opening and closing at 1.2m/s, reducing air convection

• Dual sealing of anti-mosquito brush + bottom airbag, combined with the workshop positive pressure system

Implementation Effect:

• Mosquito complaint rate decreased by 98%, and the monthly microbial testing pass rate stabilized at 99.9%

• Workshop temperature fluctuation reduced by 60%, and energy consumption decreased by more than 30%

• Logistics traffic efficiency increased by 35%, and annual loss cost reduced by over 150,000 yuan
