In this embodiment, the utility model discloses a theory of operation does:
in the pre-sterilization stage, an operator firstly communicates the fourth pipeline 13 with the circulating pipes 15 at the two ends of the homogenizer 4 through the three-way valve to lift the homogenizer 4, so that the high-temperature sterilization water cannot pass through the homogenizer 4 in the pre-sterilization stage, the homogenizer 4 is protected from being damaged by the high-temperature sterilization water at high temperature, and the service life of the homogenizer 4 is prolonged;
after the valve adjustment is finished, sterilizing water is injected into the balance barrel 1, and the sterilizing water is introduced into the first tubular heat exchanger 3 through the product pump 2 for preheating;
after the preheating is finished, the homogenizer 4 is directly overhead through the fourth pipeline 13, so that the sterilizing water directly enters the second tubular heat exchanger 5 to exchange heat with the high-temperature heating liquid in the circulating pipe 15; the second tubular heat exchanger 5 is communicated with the circulating heat exchange tube 16, and the heating liquid in the circulating heat exchange tube 16 is heated to a high-temperature state in the plate heat exchanger 19 through steam; therefore, the heating liquid in the high-temperature state can heat the sterilizing water to about 137 ℃;
the sterilizing water after being heated at high temperature further enters the third tubular heat exchanger 6, and when the sterilizing water enters the third tubular heat exchanger 6, the heating liquid which exchanges heat with the sterilizing water before in the circulating heat exchange tube 16 also enters the third tubular heat exchanger 6; because the temperature of the heating liquid is lower than that of the sterilizing water, the heating liquid and the sterilizing water exchange heat to recycle a part of heat energy of the sterilizing water and also carry out pre-cooling treatment on the sterilizing water;
after the pre-cooling is finished, the sterilizing water enters the first tubular heat exchanger 3 and exchanges heat with the sterilizing water which just enters the system in the first tubular heat exchanger 3, so that the sterilizing water which just enters the system is preheated;
then, the operator can close the fourth tubular heat exchanger 7 and the fifth tubular heat exchanger 9, and adjust the three-way valve to make the third pipeline 12 directly communicate with the first pipeline 10 and the second pipeline 11, so that the sterilizing water can directly enter the circulating pipe 15 through the first pipeline 10, the third pipeline 12 and the second pipeline 11 without returning to the balancing tank 1, and the steps are repeated to perform the sterilization treatment for 30 minutes.
The sterilizing water does not need to return to the balance barrel 1 in the pre-sterilizing process, so that the sterilizing water does not boil in the balance barrel 1, and the sterilizing water does not need to be cooled through the fourth tubular heat exchanger 7 and the fifth tubular heat exchanger 9; the fourth tubular heat exchanger 7 and the fifth tubular heat exchanger 9 can be shut down, so that the heat loss is reduced; the purpose of energy conservation is achieved.
At the end stage of the pre-sterilization, at the moment, an operator opens the drain pipes 14 on the first pipeline 10 and the second pipeline 11 and opens the fourth tubular heat exchanger 7 and the fifth tubular heat exchanger 9 to perform cooling treatment on the sterilized water to be discharged out of the system; the sterilizing water pre-stored in the balancing tank 1 is discharged from the drain pipe 14 on the first pipeline 10 by the self gravity;
at the same time, the operator injects the product liquid into the circulation pipe 15 through the feed pipe beside the product pump 2, so that the sterilizing water in the circulation pipe 15 is discharged out of the system through the drain pipe 14 on the second pipe 11; compared with the traditional scheme of injecting the product squeezing sterilizing water into the balance barrel 1 and the scheme of directly injecting the product squeezing sterilizing water into the circulating pipe 15, the mixing part of the sterilizing water and the product is in the pipeline, and compared with the mixing volume in the balance barrel 1, the mixing volume in the pipeline is less, so that the waste of raw materials is reduced, and the sterilizing cost of the product is greatly saved;
before the device of the utility model is not adopted, taking a 4 ton/hour device as an example, the steam consumption in the pre-sterilization stage is about 400-500kg for single production; 500kg of cooling water. About 150 and 200 liters of raw materials are consumed for extruding and discharging sterilizing water by a single product; when the device of the utility model is used for production, the steam consumption in the pre-sterilization stage is about 200-300 kg; 100kg of cooling water. The raw material loss is about 10-30 liters, and the raw material loss is saved by about 150 liters compared with the original raw material loss; therefore, the product has remarkable effect on energy conservation.
Finally, after the sterilizing water in the balance barrel 1 is discharged, injecting a product raw material into the balance barrel 1, preheating the product through the first tubular heat exchanger 3, homogenizing the preheated product in the homogenizer 4, and heating and sterilizing the homogenized product at a high temperature in the second tubular heat exchanger 5; then enters a third tubular heat exchanger 6 to exchange heat with the liquid in the circulating heat exchange tube 16 so as to carry out pre-cooling treatment, and then enters a first tubular heat exchanger 3 to exchange heat with the raw material which just enters the system so as to carry out pre-heating treatment on the raw material which just enters the system; finally, the temperature is reduced to the designated temperature through the fourth tubular heat exchanger 7, and then the mixture is discharged from the filling port of the filling machine 8 for filling.
