CS239391B1 - Method of disinfection of non-metallic parts of milking machines - Google Patents

Abstract

The invention proposes a method of destroying pathogens on non-metallic parts of milking equipment using microwave radiation with a frequency of 2.2 GHz for 5-10 minutes in a closed space with a volume of 0.0335 m:! with a radiator power of 500 W. The invention uses the facts that microwave radiation of a given frequency is absorbed by substances containing water, i.e. microorganisms, and converted into heat, and the radiation penetrates through non-metallic substances not containing water without effect. These facts make it possible to destroy pathogens even in microcracks and pores of non-metallic parts of milking equipment (e.g. teat liners), which was not possible by other methods (e.g. chemical rinsing).

Description

The invention proposes a method of disposing of pathogens on non-metallic parts of milking equipment by means of 2.2 GHz microwave radiation for 5-10 minutes in an enclosed space of 0.0335 m ^2. The invention makes use of the fact that microwave radiation of a given frequency is absorbed by water-containing substances, including microorganisms, and converted into heat and radiation does not penetrate through non-metallic water-containing substances. These facts make it possible to dispose of pathogenic microorganisms even in micro-cracks and pores of non-metallic parts of milking equipment (eg teck rubber), which was not possible in other ways (eg chemical flushing).

The invention relates to a method of disinfecting non-metallic parts of milking equipment by microwave irradiation.

During milking, milk comes into contact with the milking device. The milking device is washed and rinsed with disinfectant solution after each milking. This does not remove all milk residues, mainly from microscopic cracks in the teat rubber and milk-water feeders. Here, various pathogenic microorganisms, which can cause dairy gland diseases of the dairy, settle in the milk are then deposited. Some parts of the milking device, such as chewing gum, are periodically discarded from the aforementioned lines, although their mechanical properties still meet operational requirements. The complete destruction of pathogenic microorganisms using the active chlorine or iodine-based chemical agents currently in use is not achievable for microorganisms in cracks and pores.

This drawback is overcome by the disinfection of the invention. Washed and dried parts (non-metallic parts) of the milking device are exposed to microwave radiation with a frequency of 2.2 GHz in a closed space for 5–10 minutes. The effect of radiation therefore does not affect the non-metallic parts of the milking system which do not contain water, but only the microorganisms present in the cracks and pores that contain chemically bound water by destroying them by overheating.

Example:

The cured gums are free of external impurities and dried and exposed to 2.2 GHz microwaves for 5-10 minutes.

The advantage of this method is that it enables the elimination of pathogenic microorganisms hidden in micro-cracks and pores of non-metallic parts of the milking equipment, which the prior art disinfection methods did not allow.
