Abstract
The article presents the results of production tests of three designs of mechanical cleaners intended to increase the efficiency of sanitary processing of milking installations. As a result of the experiment, the optimal number of mechanical cleaners and their type were determined. The optimization criterion was the total microbial number (KMAFAnM) obtained as a result of seeding on the nutrient medium of washings from the inner surface of the milk line. As a result of the experiment, it was determined that the optimal result is achieved by sanitizing a milking unit with 4-5 mechanical cleaners with a cleaning surface of bristles.
Highlights
Milk production is one of the largest and most promising sectors of the agricultural sector
The experiment was planned to determine the optimal amount of supplied mechanical cleaners and their type, as well as to identify their mutual influence on the quality of cleaning the inner surface of the milk pipeline [15]
As a result of the study, the following conclusions can be drawn: 1. The use of mechanical cleaners for circulating washing of milking units is an effective measure. It allows reducing the level of bacterial contamination of the inner surface of the milking unit by more than 30%
Summary
Milk production is one of the largest and most promising sectors of the agricultural sector. Together with increasing the amount of milk produced, each producer strives to improve its quality, because its price in the market depends on the physicochemical parameters of milk. It should be noted that the main two groups of factors affect the quality parameters of milk:. - providing production (lactation period, breed of cows, their health status, conditions of detention, diet and quality of feed);. - ensuring safety (technology of milking cows and primary milk processing). Our research team is directly involved in ensuring the safety of milk after dispensing. The main reason for reducing the quality of milk is the activity of microorganisms, the bulk of which gets into it as a result of contact with the environment and the internal surfaces of the milking equipment
