液态奶工厂贮奶罐清洗工艺和效果验证的研究

贮奶罐（特指“立式贮奶罐”）是液态奶工厂重要的产品暂存设备,其自身的清洗效果不好会对贮存的产品造成污染,影响产品品质。贮奶罐的清洗因其大小、结构的不同,内容物的产品特性的不同,所采用的清洗工艺和清洗装置也有所不同。本文从贮奶罐分类和构造,CIP清洗参数设定,如温度、清洗液浓度、机械力、时间、产品特性,清洗装置的选配,如洗球选型、连杆长度、连接方式,清洗效果验证方法等方面进行阐述。合理的清洗工艺设计可有效规避或减少清洗问题,降低因罐体清洗不净而给产品质量带来的风险;贮奶罐清洗效果的验证,可让清洗工艺设计更加具有适宜性和有效性,并可及时发现贮奶罐的清洗问题。

Design of Cleaning Technology and Cleaning Effect Verification Method of Milk Storage

Milk storage tanks（especially“vertical milk storage tanks”） are important product temporary storage equipment for liquid milk factories,and their own poor cleaning effect can cause pollution to stored products and affect products quality. The cleaning process and cleaning devices used in the milk storage tanks are different due to the difference in size and structure,and the products characteristics of the contents. This paper described the classification and structure of milk storage tanks,the setting of CIP cleaning parameters,such as temperature,cleaning solution concentration,mechanical force,time,product characteristics;the selection of cleaning devices, such as the selection of the washing ball,the length of the connecting rod,and the connection method;verification method of cleaning effect. Reasonable cleaning process design can effectively avoid or reduce cleaning problems,and reduce the risk of product quality due to unclean tank cleaning. Verification of the cleaning effect of the milk storage tanks can make the cleaning process design more appropriate and effective,and can detect the cleaning problem of the milk storage tanks in time.
