Description

TECHNICAL FIELD

[0001] The utility model relates to material heating technical field, specifically is a kind of heating circulation system. BACKGROUND

[0002] In the industrialized production process of modern Chinese patent medicine, the concentrating link as the key step linking the extraction of medicinal materials and the subsequent preparation forming plays a decisive role in product quality and cost control. When the medicinal material extract is concentrated, heating operation is the core of the concentration process.

[0003] At present, the heating methods widely used in the industry mainly concentrate on steam heating, gas heating and water bath heating. However, these traditional heating methods have exposed many defects in actual application. On the one hand, from the perspective of energy utilization efficiency, whether it is high-temperature steam generated by steam heating or a large amount of waste heat generated in the gas heating process, after completing the heating mission of the inner tank body medicinal material extract, it is usually directly discharged to the external atmospheric environment without any recovery or secondary utilization treatment. This means that in the whole concentration process, a large amount of valuable heat energy contained in steam and hot gas is wasted, and enterprises need to continuously invest more energy to maintain the heating demand, which makes the production cost rise straight.

[0004] Taking steam heating as an example, high-pressure steam produced by the boiler house is delivered to the concentration device through the pipeline, becomes low-temperature steam after releasing heat, and is directly discharged into the atmosphere, and a large amount of latent heat carried by it is not utilized; when gas heating, the high-temperature flue gas generated by combustion is also directly dissipated after heating the tank body, and the heat utilization rate is often less than 50%. Water bath heating is relatively energy-saving, but it takes a long time to heat up, consumes a lot of energy to maintain high temperature, and the heating water is frequently replaced and discharged, which also causes hidden loss of energy.

[0005] On the other hand, with the increasingly fierce market competition, the price of traditional Chinese medicinal materials fluctuates and rises, and pharmaceutical enterprises face huge cost pressure in each production link. The low energy efficiency of the heating link directly translates into high processing cost of medicinal materials, which compresses the product profit space and weakens the price competitiveness of enterprises in the market. Moreover, extensive heat discharge may also have a certain heat pollution effect on the surrounding environment.

[0006] In summary, the existing Chinese patent medicine concentration heating technology needs to be innovated and reformed, and a new type of concentration heating device that can ensure efficient and uniform heating to ensure product quality, realize energy recovery and utilization, reduce production cost, meet environmental protection requirements, and help Chinese patent medicine industry break through the development bottleneck is urgently needed.
