Abstract: A dryer (100), comprising a dryer chamber (101) coupled to a closed loop gas-circulating system for circulating gas through the dryer chamber (101); wherein the closed loop gas-circulating system recirculates the gas and comprises: a compressor (113) coupled to receive return gas from the dryer chamber (101) and to compress the return gas to provide compressed gas; a separator (109) sitting in the gas-circulating system for draining condensate from the gas; and a gas discharger (103; 104) coupled to receive compressed gas from the compressor (113) and to discharge the compressed gas through a discharger exit (118). The separator sits in the closed loop gas-circulating system downstream of the compressor to receive compressed gas and upstream of the gas discharger (103;104). Thereby drying efficacy is improved and is advantageous at relatively low drying temperatures such as below 40 degrees Celsius.

Abstract: According to the invention a method (and corresponding system) of enhancing application of high intensity acoustic waves is provided, wherein acoustic waves, e.g. ultrasound, and a gaseous medium, e.g. steam, coincide at a treatment zone. This is achieved by a combination of one or more high intensity acoustic generators and/or reflectors. In this way, enhanced efficiency in an area of the gaseous medium (or where the gaseous medium is to affect something) is obtained since a second generator or a reflector is located so that the acoustic waves directly influence the gaseous medium.

Abstract: A method and an apparatus in form of a disinfecting apparatus comprising a steam device for combating 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.
