Fuwei Enterprise Co., Ltd. has invested in twist production and research and development since 1991. Considering that the frequent contact of handmade twisted rolls is likely to cause pollution, we invested heavily in the establishment of an automated process factory in 2018, and all products are changed to automated manufacturing in 2020. ISO22000 (food management standards) and HACCP are introduced in the process to improve food hygiene and quality control. , Obtained FSSC22000 international certification in 2021 to standardize the production process, and each twisted roll can meet the quality stability and hygiene requirements.
