Efficient washing of milking units

   The cleaning and disinfection of milking equipment are extremely important for obtaining high-quality milk. When washing the milking system, the most problematic, costly, and time-consuming operation is to flush teat cups. To optimize the process, the authors carried out analytical studies of air-hydraulic mixture velocity in the teat cup. They have developed a washing device for milking unit, including a feeding system of collector type for distribution of a washing solution into four cone-shaped rotating nozzles with mechanically active surface of arbitrary rotation. The uniform and volumetric supply of the washing liquid to the contaminated surface of the teat cup rubber is carried out through the cone-shaped nozzles. On their surface, there are jet atomizers and bristles providing friction washing. The collector platform with nozzles allows teat cups to be connected without disassembling the milking unit. With the help of an electronic pulsator and a one-way valve mechanism it is possible to simultaneously wash milk hoses and the collector of the milking unit in a non-disassembling way. Increasing the intensity of impact on the inner walls of the teat cup rubber, filling the suckling chamber of the teat cups with washing liquid and reducing the washing time with localizing the milking unit washing circulation. In addition, it significantly accelerates the disinfection of milking machines, reduces the washing time at least twice and reduces the consumption of detergents, proportional to the reduction of washing time, while washing the milking unit.
