An embodiment of the plate heat exchange device for the tail liquor of the present invention is composed of a first stacked plate fixing plate 1, a plate group 2, a second stacked plate fixing plate 3, and a fixing bracket 4, which is used to rapidly reduce the temperature of the tail liquor during the liquor brewing process.

[0025] Plate group 2 is composed of multiple stacked plates, forming the main body of the plate heat exchanger. Independent tail liquor and cooling medium channels are formed between the plates in plate group 2, each created by combining through-holes on adjacent plates. The tail liquor and cooling medium flow in adjacent channels, exchanging heat through the plates. The plate surfaces are designed with a corrugated structure and are made of food-grade stainless steel, increasing the heat exchange area and fluid turbulence, significantly improving heat exchange efficiency. Alternatively, the plate surfaces can employ a honeycomb structure or other structures to enhance turbulence, and the material can be food-grade titanium alloy or other food-grade corrosion-resistant materials to ensure equipment hygiene and safety.

[0026] The first stacked plate fixing plate 1, plate group 2, and second stacked plate fixing plate 3 are fixedly connected as a whole by bolts 5. The first stacked plate fixing plate 1 is provided with a tail liquor inlet 9, a tail liquor outlet 7, a cooling medium inlet 8, and a cooling medium outlet 6. The tail liquor inlet 9 is located at the top right end, the tail liquor outlet 7 is located at the bottom left end, the cooling medium inlet 8 is located at the bottom right end, and the cooling medium outlet 6 is located at the top left end. The inlet and outlet of the tail liquor flow channel and the cooling medium flow channel both face the first stacked plate fixing plate 1. The inlet and outlet of the tail liquor flow channel are respectively connected to the tail liquor inlet 9 and the tail liquor outlet 7, and the inlet and outlet of the tail liquor flow channel are respectively connected to the cooling medium inlet 8 and the cooling medium outlet 6, ensuring countercurrent heat exchange and facilitating rapid cooling of the tail liquor to improve the heat exchange effect.
