污垢是食品工业中的主要问题。在涉及过敏原的情况下，通常会对食品加工设备进行过度清洁，以确保过敏原水平降低到可接受的水平。在中试规模的清洗装置中进行了实验测试，以评估流体流速和温度对现场清洗过程中奶糊去除率的影响。对试验期间进行的电导率测量进行分析，以产生一个方程，该方程能够计算具有水温、流速、初始存款质量和时间的清洁速率。还研究了用洗涤剂清洗的速率。这种方法产生了一个基于速率的清洁表达式，可应用于其他产品，并可用于确定清洁完成的时间，清洁过程的程度，或何时应用洗涤剂冲洗代替预冲洗。这可以防止过度清洗，从而降低与过度清洗相关的能源、材料和生产时间损失成本。
Fouling is a major problem in the food industry. In cases where allergens are involved, excessive cleaning of food processing equipment often takes place to ensure allergen levels are reduced to acceptable levels. Experimental trials were conducted in a pilot scale cleaning rig to assess the effect of fluid flow rate and temperature on the removal rate of milk paste during cleaning-in-place. Conductivity measurements taken during trials were analyzed to produce an equation enabling calculation of the cleaning rate with water temperature, flow rate, initial deposit mass, and time. The rate of cleaning with detergent was also investigated. This methodology produces a rate-based expression for cleaning, which can be applied to other products, and can be used to determine the time when cleaning is complete, the extent of a cleaning process, or when the prerinse should be replaced with a detergent rinse. This prevents overcleaning and therefore reduces the costs associated with overcleaning through energy, material, and loss of production time.
