Installing actual throttle hole diameter for inleting air into dairy collector camera depending on intensity of milk product and dairy hose diameter

Abstract

One of the main processes in dairy cattle breeding is the process of milking cows, in the total costs of milk production, its share is about 70%. The milking machines used today in Ukraine differ significantly both in design and in the organization of milking technology. No machine used today in the agro-industrial complex comes in contact with a living organism like a milking machine. Therefore, design defects adversely affect the physiological condition of the animal and the quality of the milk obtained.
Dairy production technology must meet current requirements and ensure the cost-effective production of high-quality milk with a thrifty attitude to animal health. The quality of milk depends on many factors: the feed base, the conditions of maintenance, the sanitary condition and the technical characteristics of the equipment. According to statistics in our country, farms of different categories produce extra milk of about 16%, higher grade – 35% and first grade at 40%. It is important to maintain the quality of milk during machine milking. There is a problem of removing milk from the collector's milk collector into the upper milk line (for milking machines), especially in the process of machine milking of high-yielding cows, when there is a delayed removal of
milk from the collector and a ripple flow in the milk hose. According to research, it is found that when milking in the upper mammary tube, the loss of milk fat is from 0.16% to 0.3%. In addition, shaking milk in milk hoses creates a lot of foam, the fat content of which reaches 12-15%. The reason is non-compliance and breach of milking technology. This calls for increased attention to milking technology, as it can cause milk loss from 25% to 30% due to the breach of milking technology, and incomplete milking from the udder loses up to 12% of its fat content.
