对鱼糜生产排放废水中鱼糜回收的技术工艺设备和回收鱼糜的再利用等技术进行了系统研究。结果表明 ,(1)废水中固形物含量 1.2 %～ 1.8% ;其中鱼糜含量 0 .6 %～ 1.2 % (鱼糜按水分 80 %计 ) ;(2 ) p H值为 5.2～ 5.4时 ,鱼糜回收率最高 ,在 95%以上 ;(3)鲜度差的原料 ,鱼糜回收量大 ;(4 )添加 0 .0 4 % Ca Cl2 对回收鱼糜的脱水有显著效果 ;(5)利用高位连续释放的方法回收鱼糜 ,有利于鱼糜的连续回收
Systematic research was conducted on the technology and equipment for the recovery of surimi from the waste water from surimi production and the reutilization of surimi. The results showed that: (1) The content of solid in waste water was 1.2% -1.8%; the content of surimi was 0.6% ~ 1.2% (surimi was 80% of water); (2) The surimi recovery rate is the highest, more than 95%; (3) the raw material with poor freshness has a large recovery amount of surimi; (4) the addition of 0.040% Ca Cl2 has a significant effect on the dehydration of the recovered surimi; The use of high continuous release of surimi recovery method is conducive to the continuous recovery of surimi
