关于长沙市生湿面生产企业空气净化设施使用情况的调查分析
Investigation and Analysis on the Use of Air Purification Facilities in Fresh Wet Noodles Production Enterprises in Changsha

本研究旨在分析生湿面生产企业空气净化设施的使用必要性，并为生湿面企业取消空气净化限制条件提供依据。调查选取了长沙市内处于生产状态的18家生湿面生产企业作为研究对象，重点调研了空气净化级别和维护频率、菌落总数监测频率和限值、企业集中反映问题。分析结果表明，从生产成本、设施效果、运行影响等方面综合考虑，空气净化并非控制环境微生物、保证产品品质的必要设施。
