Description

Technical Field

[0001] The utility model relates to the technical field of oral liquid production, in particular to a cooling structure of an oral liquid preparation system. Background Art

[0002] Yishen Wufa oral liquid is a Chinese patent medicine. The preparation process is to suck the clear paste into the preparation tank - add auxiliary materials (refined honey, sugar, sodium benzoate) - turn on the stirring paddle to stir - open the steam valve to heat and boil - use circulating cooling water to cool down - adjust Ph to the specified range - add water to adjust the specific gravity - confirm that the specific gravity Ph is qualified - the prepared liquid medicine is poured into the cold storage tank - and introduced into the temporary storage tank. At present, circulating cooling water is used. A cooling tower is set up outside the workshop and a heat exchanger is set up inside the workshop. The liquid outlet pipe and liquid return pipe of the preparation tank are connected to the heat exchanger through a circulating pump. The cooling water in the cooling tower is connected to the heat exchanger through a water pump. After the liquid medicine is heated, it circulates through the heat exchanger and is cooled to 28 degrees by the cooling water in the heat exchanger. According to the company's initial design, the cooling water in the cooling tower can meet the needs of circulating cooling liquid medicine. However, with the gradual expansion of production capacity and the production teams producing day and night, the heat dissipation efficiency of the cooling tower has not changed and it circulates 24 hours a day, resulting in a high temperature of the cooling water, which results in a long cooling time of the liquid medicine, and finally leads to low production efficiency. In addition, due to the continuity of production, the heat dissipation improvement of the existing cooling tower cannot be constructed. The shutdown will cause delays in the construction period, and the cost of building an additional cooling tower is high, which is not worth the loss. Utility Model Content
