Cooling device for dairy products after hot filling

Abstract

The invention relates to a cooling device for dairy products after hot filling. The device comprises a conveyor belt, and a water cooling mechanism, a first air cooling mechanism and a second air cooling mechanism which are sequentially arranged in the conveying direction of materials on the conveyor belt; the water cooling mechanism comprises a water cooling cover plate arranged above the conveyor belt; the bottom of the water cooling cover plate is uniformly provided, at an interval, with a plurality of water cooling nozzles which are used for spraying cold water to the materials on the conveyer belt; the first air cooling mechanism comprises an air cooling cover plate arranged above the conveyer belt; the bottom of the air cooling cover plate is provided with a plurality of first air cooling nozzles which are used for spraying cold air to the materials on the conveyer belt; the second air cooling mechanism comprises a pair of air cooling side plates arranged at two sides of the conveyer belt; the inner side of each air cooling side plates is provided with a plurality of second air cooling nozzles which are used for spraying cold air to the materials on the conveyer belt; and thedirection, in which the second air cooling nozzles spray cold air, is in obliquely downward. The cooling device has the beneficial effects that the whole volume of a cooling mechanism is smaller, andcooling effect is better.

Description

technical field [0001] The invention relates to a cooling device, in particular to a cooling device for milk products after hot filling. Background technique [0002] Liquid materials such as milk need to be cooled before being hot-filled into bottles, cans, bags and other containers through the conveying device before entering the next process (such as packaging or labeling, etc.), otherwise it will affect the smooth progress of the next process. Existing cooling devices usually only include one air-cooling structure to cool the milk products after hot filling. In the actual production process, it is found that if only a single air-cooling structure is installed to cool the dairy products to an appropriate temperature, usually It is necessary to set the air-cooling structure longer along the conveying direction of the material. In addition, when a single air-cooling structure is provided, the air outlet direction is generally relatively single, resulting in poor cooling ef...
