Description
Technical Field
The utility model relates to a beverage production technical field, in particular to two UHT system beverage production lines.
Background
Almost all drinks are sterilized by heat treatment, and the sterilization temperature reaches 100 ℃ and 140 ℃ or above. A conventional heat treatment plant is a UHT system, plate UHT or tube UHT being chosen according to the product characteristics. The two main differences are that the types of the heating heat exchangers are different, one adopts a plate heat exchanger, the other adopts a tubular heat exchanger, but the sterilization processes of the two are the same, and the beverage is directly heated or indirectly heated by a steam heat source. No matter which heat exchanger is selected for heating, the problem of scaling of the inner surface of the heat exchanger during production cannot be avoided, and equipment needs to be shut down for cleaning after a UHT system is seriously scaled.
The concentrated juice or protein content of the fruit and vegetable puree, jam, soymilk, tomato juice, high-protein dairy products and the like is higher. In the production process of UHT heat treatment sterilization, a scaling layer can be formed on the inner surface of the heat exchanger within a short time, the overall heat exchange efficiency is reduced after the scaling layer appears, and the temperature of a heat exchange medium can only be continuously increased to compensate. Along with the increasing temperature difference between the materials and the heat exchange medium, the fouling layer close to the metal surface of the heat exchanger can also be coked and gelatinized, and the fouling layer is formed intensively. The scaling layer gradually thickens and then drops, and the scale formation lump and the burnt black particulate matter that drop when serious will enter into the filling equipment of rear end together along with the material and carry out the filling, influence the product quality. In order to avoid the phenomenon that scaling blocks and burnt black particles which appear after UHT heat treatment are mixed into finished products, a production line can only be stopped periodically, UHT equipment is cleaned by complex CIP and sterilized by SIP and then put into use again, other equipment can only be stopped for waiting in the process, and a large amount of time and standby energy are wasted.
