Abstract: There is provided a method for monitoring deposit build-up on spray nozzles in a spray drying or spray cooling chamber. The method comprises feeding drying air or cooling air into the chamber, and feeding a feed material to be spray dried or spray cooled into the chamber through one or more spray nozzles, thereby obtaining one or more sprays of feed material in contact with drying or cooling air. A digital reference image is obtained, which reference image has an image area comprising a first area of interest covering at least part of a spray nozzle and/or part of a feed material spray corresponding to a spray nozzle. A number of process images are obtained and recorded, where the process images cover the same image area as the reference image, and at least part of the recorded process images are compared with the reference image, and a difference, if any, is detected for the first interest area between the reference image and the process images being compared to the reference image. A notification or error notification may be issued based on the detected differences. The notification may be issued when a predetermined minimum difference is detected for each of a predetermined number of recorded process images. The present invention also provides a system for monitoring spray nozzles in a spray drying or spray cooling chamber.

Abstract: A plant for heat treating heat-sensitive fluid foodstuffs an infusion chamber in which the fluid foodstuff is subjected to a heat treatment by a feeding of steam, and a fluid foodstuff inlet connected to a plurality of openings at the top of the infusion chamber for creating a plurality of essentially downwardly directed separate fluid foodstuff jets. The infusion chamber has a bottom section configured to collect the fluid foodstuff from the jets. The bottom section has an outlet opening at the bottom of the infusion chamber for allowing the collected fluid foodstuff to exit the infusion chamber. The outlet opening is seamlessly connected to the inlet of a pump. A cooling jacket surrounds the bottom section for cooling the bottom section. The cooling jacket extends all the way down to the pump.
