Abstract
Description
Technical Field
[0001] The utility model relates to a beer hot wort precooling system, belonging to the field of beer brewing equipment. Background Art
[0002] In the beer brewing process, the hot wort temperature of about 98℃ needs to be reduced to below 10℃ before fermentation. We usually use a one-stage plate heat exchanger to cool the hot wort to a suitable temperature (below 10℃) for fermentation. During continuous production in summer, the hot water generated by heat exchange in the saccharification workshop cannot be fully used, resulting in excess and waste of heat energy. The large temperature difference will also cause the use of refrigerant (ice water), increasing production costs. Utility Model Content

[0019] See also Figure 1 The plate heat exchanger 1 and the plate heat exchanger 2 are both provided with a CIP cleaning system. Through the design of the CIP cleaning system, the plate heat exchanger 1 and the plate heat exchanger 2 can be flushed before the equipment is used, which not only meets the hygiene requirements but also protects our equipment from being corroded by scale.
[0020] When in use, the hot wort (92°C~98°C) in the sedimentation tank enters the plate heat exchanger 1 through the hot wort supply pipe 3 for precooling. At this time, the warm water supply pipe 5 transports warm water (68°C) to the plate heat exchanger 1, and the warm water and the hot wort exchange heat to achieve the precooling effect. The warm water (87°C) after the heat exchange is transported to the water storage through the return pipe 6, and the precooled hot wort (75°C) is transported to the plate heat exchanger 2 through the pipeline 14. At this time, the refrigerant (3°C ice water) in the refrigerant tank 10 enters the plate heat exchanger 2 The hot wort (75°) is used for heat exchange. Since the hot wort (75°) has been pre-cooled and the temperature is not very high, only a small amount of refrigerant (3°C ice water) is needed to reduce it to a suitable temperature (below 10°C). This not only saves the cooling capacity of the refrigerant, but also speeds up the refrigeration rate, reduces the cost and improves the rate. At the same time, the plate heat exchanger 1 heats the 68°C warm water transported by the warm water supply pipe 5 to 90°C through heat exchange, thereby improving the energy quality. In addition, the heated warm water can be used in other workshops such as packaging, thereby improving the energy utilization rate.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
