Abstract
A method and an apparatus in form of a disinfecting apparatus comprising a steam device for combatting germs on the surface of products, in particular of food products. The apparatus employs a combination of steam and ultrasound to kill germs on the surface of a product which is conveyed past the steam device. Pressurized steam is fed through a steam passage to an opening conveying the steam to a cavity, in which the steam is made to oscillate at a ultrasonic frequency. The oscillations in the steam prevent the steam from heating the products excessively, while germs presents on the surface of the products are heated and killed.
Claims12
Method for disinfecting a product by surface treatment thereof, steam of a liquid, preferably aqueous steam, and sound, preferably ultrasound, being discharged to the surface of the product, characterised in that ultrasound is generated without inducing cavitation and at the same time as steam is diffused and made to oscillate at a frequency in the ultrasonic range at such a high acoustic pressure that the migration of the individual molecules exceeds the dimensions of the bacteria or germs to be killed.
Method according to one or more of the preceding claims, characterised by a relatively short processing time.
