Sizing Vacuum Pumps for Cleaning Milking Systems
نویسندگان
چکیده
Early pipeline milking systems were commonly flooded during cleaning. Flood cleaning is practical for systems with small diameter milklines, short pipelines and few milking units. Flood cleaning becomes impractical as milkline diameter and length and the number of milking units is increased. Excessive water volume is required and the flow velocities and corresponding mechanical cleaning action produced are low. Air injection was introduced to overcome these limitations.

Lhc: the World's Largest Vacuum Systems Being Commissioned at Cern
When it switches on in 2008, the 26.7 km Large Hadron Collider (LHC) at CERN, will have the world's largest vacuum system operating over a wide range of pressures and employing an impressive array of vacuum technologies. This system is composed by 54 km of UHV vacuum for the circulating beams and 50 km of insulation vacuum around the cryogenic magnets and the liquid helium transfer lines. Over ...
متن کاملEquipment Specifications and Methods for Dynamic Testing
Both the new ASAE S518 standard (2) and the revised draft international standard DIS/ISO 5707 (3) incorporate performance standards for vacuum stability in milking systems. New NMC procedures for system evaluation include dynamic tests for vacuum stability to demonstrate the adequacy of new or existing milking systems (7) . Such dynamic (i.e. "milking-time") tests require the use of test instru...
متن کاملEfficiency of cleaning procedure of milking equipment and bacterial quality of milk
The cleaning and sanitation of milking equipment could be consider a critical point in the milking procedure because a cleaning failure could influence the level of bacteria contamination of bulk tank milk. Aim of the study is to monitor the cleaning procedures of milking systems in 7 dairy cows farms in Lombardy and to find a relation between efficacy of cleaning system and the bacterial quali...

In this study, a new quarter individual milking system called Multilactor® (MULTI) was compared with a conventional milking system (CON). The target of the developments in the field of milking technique is to obtain the whole milk from the teat of the animal in the shortest possible time without causing any detrimental effect on udder health. The most direct measure of the milking system effect...
متن کاملDrinking and Cleaning Water Use in a Dairy Cow Barn
Water is used in dairy farming for producing feed, watering the animals, and cleaning and disinfecting barns and equipment. The objective of this study was to investigate the drinking and cleaning water use in a dairy cow barn. The water use was measured on a well-managed commercial dairy farm in North-East Germany. Thirty-eight water meters were installed in a barn with 176 cows and two milkin...
