食品車間凈化最好能與外界隔離，不能穿行或者受其他因素干擾。食品車間凈化的大小依需要的而定，一般由更衣間、緩沖間、臨沂風淋室和(he)操(cao)(cao)作間(jian)(jian)(jian)等組(zu)成。更衣間(jian)(jian)(jian)放(fang)在外，主要(yao)供更換衣帽、鞋子等;緩沖間(jian)(jian)(jian)應該位于更衣間(jian)(jian)(jian)與風淋室之間(jian)(jian)(jian)，也可(ke)以(yi)同時和(he)幾個操(cao)(cao)作間(jian)(jian)(jian)相(xiang)通;操(cao)(cao)作間(jian)(jian)(jian)放(fang)在內間(jian)(jian)(jian)，主要(yao)供產品灌裝(zhuang)(zhuang)，房間(jian)(jian)(jian)不(bu)能受日(ri)光(guang)直射，大小(xiao)適(shi)當，高(gao)度適(shi)宜(具體根(gen)據生產設備的高(gao)度來確定)。房間(jian)(jian)(jian)過大，清掃和(he)消(xiao)毒(du)不(bu)便;過小(xiao)，操(cao)(cao)作不(bu)便;如果(guo)頂(ding)部(bu)過高(gao)會影響(xiang)紫外線的有效(xiao)滅菌效(xiao)果(guo)。墻(qiang)壁應光(guang)滑無(wu)死角，以(yi)便清洗和(he)消(xiao)毒(du)。食品、食品車(che)間(jian)(jian)(jian)凈化應為(wei)密閉式并保(bao)持車(che)間(jian)(jian)(jian)靜壓(ya)差(cha)為(wei)正壓(ya)，設置空氣消(xiao)毒(du)用的紫外線燈、空氣過濾凈化器和(he)恒溫裝(zhuang)(zhuang)置。
