RU43729U1 - MILKING INSTALLATION - Google Patents

Abstract

Usage: in livestock during machine milking of cows, mainly in stalls in the milk line.

The milking unit includes milking machines, a vacuum line, a milk line and an air separator communicating with the atmosphere through an air line with an air purifier in the form of an autonomous nitrogen gas generator that operates on the principle of short-cycle heat-free adsorption at ambient temperature, allowing gases such as nitrogen and oxygen. During milking and transportation through the milk pipeline, freshly milked milk is exposed to an inert gas atmosphere of nitrogen, which prevents the growth of acidity and the formation of an odor. Another part of the purified atmospheric air enriched with oxygen is fed into the livestock building, improving the microclimate and improving the service conditions of the milking unit.

Description

The utility model relates to animal husbandry, to devices for machine milking cows, can be used mainly for milking in stalls in a milk line.

Known milking installation, including rotary vacuum and milk pipelines with a vacuum regulator, communicating with the atmosphere outside the livestock building SU 360044, A 01 J 5/00, 01/01/1972.

The known installation ensures the suction of clean air into the milk and vacuum pipelines, while the ingress of dusty and harmful bacterial contaminants present outside the livestock building is not ruled out.

A known milking unit, including a vacuum pump, a vacuum regulator, a vacuum line, a milking milk pipe with milking machines, an air separator and a milk pump, and a clean air pipe with a supercharger, a cleaner and a disinfectant of atmospheric air entering it. At the same time, the air separator, vacuum regulators and collectors of the milking machines are in communication with the atmosphere through the clean air pipeline SU 1007614, A 01 J 5/00, 03/30/1983.

The known design of the milking unit prevents the contamination of milk from the air, but does not allow to maintain the acidity of freshly milked milk. Milk is an easily oxidizable product, and in the process of milking and transportation through the milk pipeline, exposure to oxygen from purified atmospheric air accelerates the growth of its acidity. Acidity is the main physicochemical indicator by which the freshness and, therefore, the quality of milk is judged.

In addition, in the known installation, the air purifier, being in a stall livestock breeding room, does not preclude the saturation of milk with extraneous odors caused by the conditions of the cows and the presence in the chemical composition of the air of such harmful gases as carbon dioxide in excess, ammonia and hydrogen sulfide.

The objective of the utility model is to improve the quality of freshly milked milk.

The technical result from the use of the utility model is to slow down the increase in the acidity of milk during milking and transportation through the milk pipeline, preserve the natural odor and improve the conditions of service by personnel by enriching the atmospheric air in the livestock building with oxygen.

The technical result is achieved by the fact that in a milking unit, including milking machines, a vacuum line, a milk line and an air separator communicating with the atmosphere through an air pipe with an air purifier, the latter is made in the form of an autonomous nitrogen gas generator that operates on the principle of short-cycle heat-free adsorption at ambient temperature .

The use of a nitrogen gas generator as an air purifier in the design of the milking unit allows the communication of the atmospheric pressure channels and chambers of the collectors and pulsators of the milking machines, the vacuum regulator of the vacuum line, the milk line and the air separator with gaseous nitrogen at atmospheric pressure.

The implementation of the gaseous nitrogen generator autonomous, operating on the principle of short-cycle heating without adsorption at ambient temperature, allows the production of nitrogen from the ambient air directly at the place of consumption

and to operate it both in the livestock building, and on sites under a canopy in the summer.

Milking installation works as follows.

The milking machines prepared for work are simultaneously connected to a vacuum line, a milk line and an air line with an autonomous nitrogen gas generator. The latter, operating on the principle of short-cycle heatless adsorption at ambient temperature, allows the production of gases such as nitrogen and oxygen from atmospheric air. Nitrogen gas after purification of atmospheric air in the generator through the nozzles of the air pipeline at atmospheric pressure enters the pulsator, milk collector chambers and suction cups of milking machines, into the sealed chambers of the vacuum regulator of the vacuum line, into the milk pipe and the air separator. Thus, during milking and transportation through the milk pipeline, freshly milked milk is exposed to an inert gas atmosphere of nitrogen, which prevents the growth of acidity and the formation of an extraneous odor.

Another part of the purified atmospheric air enriched with oxygen is fed into the livestock building, improving the microclimate and improving the service conditions of the milking unit.

So, for example, in the experimental milking unit, made on the basis of a typical ADM-8 installation, an NG-1 nitrogen generator was used as an atmospheric air purifier, which is used to regulate the atmosphere in fruit and vegetable product storages and granaries, and which can be operated in industrial premises of category “B” according to ONTP 24-86 or under a canopy at an ambient temperature of 5 ° C to 35 ° C, atmospheric pressure from 700 to 800 mm Hg. and relative humidity of air no more than 80% at 25 ° С. The NG-1 generator produces nitrogen from ambient air directly at the place of consumption and operates on the principle of

short-cycle heatless adsorption using air above atmospheric pressure at the adsorption stage and depressurizing to atmospheric at the desorption stage. The generator is fully automated. There is no need for consumables throughout the entire service life.

The use of an experimental setup for milking cows in the summer made it possible to obtain high-quality milk with an acidity level (15.08-15.36) ° T, which remained stable for 36-40 hours and with a taste and smell without impurities of harmful gases.
