所有的食品加工厂都必须进行清洁，以确保卫生操作，但清洁还没有得到很好的理解。微操作探针已经被开发出来，它可以测量破坏和去除表面沉积物所需的力。这里，测量了从表面去除不同高度x处的番茄酱存款所需的力。在较小的x时，去除存款所需的功随高度而增加，并且是表面性质的函数，而在较大的x时，所需的功随x的增加而减少，并且不是表面的函数。已经开发了两个简单的模型，适合数据和观察的清洗;这些是基于（i）在小x，在断裂的存款和运动在表面上，和（ii）在较大的x，在断裂的沉积物-存款债券和去除均匀层。(c)2006爱思唯尔有限公司版权所有。
All food process plant must be cleaned to ensure hygienic operation, but cleaning is not well understood. Micromanipulation probes have been developed which can measure the force required to disrupt and remove deposits from surfaces. Here, the forces required to remove a tomato paste deposit at different heights x from the surface have been measured. At small x, the work needed to remove the deposit increases with height and is a function of the nature of the surface, whilst at larger x the work needed decreases with increasing x and is not a function of the surface. Two simple models have been developed which fit the data and observations of cleaning; these are based (i) at small x, on the fracture of the deposit and motion across the surface, and (ii) at larger x, on the fracture of deposit-deposit bonds and removal of a uniform layer.
