Fuente: WIPO "processing tomato" The utility model provides concentration evaporation type rectification equipment, which relates to the technical field of tomato sauce processing, and comprises a concentration box body, the outer surface of one side of the concentration box body is fixedly communicated with a feed pipe, the front surface of the concentration box body is provided with a processing control device, and the center of the bottom of the concentration box body is provided with a feed opening. The driving motor is started to drive the driving shaft to rotate, the effect of driving the U-shaped frame and the heating rod to rotate and stir tomato sauce inside is achieved, the heating effect is improved, when the U-shaped frame rotates, the spring inside the embedded groove extrudes the connecting rod outwards, the connecting rod pushes the scraper to be tightly attached to the inner wall of the concentration box body, and the stirring effect is improved. When the scraping plate rotates along with the U-shaped frame, the scraping plate has the effect of scraping tomato sauce hung on the wall, and when the U-shaped frame is abraded, the U-shaped frame is always tightly attached to the inner wall of the concentration box body under the extrusion of the spring, so that the problem that the tomato sauce is hung on the wall due to abrasion is solved.
