Description

Technical Field

[0001] The utility model relates to the technical field of rapeseed flower extraction, in particular to a production system for rapeseed flower extract. Background Art

[0002] Rapeseed, also known as Brassica rapa, is native to Europe and Central Asia and is an annual herb in the Brassicaceae family. In my country, rapeseed flowers are concentrated in the Huangling Mountains in Wuyuan, Jiangxi Province, the Hanzhong Basin, the Jiangling Ten Thousand Mu Terraces, the Luoping Plain in Yunnan Province, and the Menyuan Plateau in Qinghai Province. Rapeseed flower extract has biological functions such as enhancing immune activity, lowering blood lipids, and fighting tumors. Existing rapeseed flower extract extraction equipment often uses stainless steel extraction kettles or immersion pots. Stainless steel kettles have good thermal conductivity. Overheating a stainless steel kettle can destroy certain components, thereby affecting the efficacy of the drug. During use, stainless steel kettles may chemically react with certain acidic or alkaline components in the extract, damaging the oxide film on the pot surface and shortening the pot's service life. This can also cause rust and discoloration on the pot surface. Stainless steel kettles easily absorb substances such as oil and pigments during use, making the pot surface greasy and difficult to clean. The condensed coolant collected in the receiving tank of the rapeseed extract concentration device is often at a high temperature. In the actual production process, during continuous production, it is often necessary to discharge the liquid in the receiving tank in time, recycle it, add it to the extraction device, or discharge it away. However, the liquid in the existing receiving tank is often at a high temperature, which can easily cause accidents such as burns during recycling or discharge. Therefore, it is necessary to lower the temperature of the condensed coolant collected in the receiving tank to a lower level for subsequent processing. Utility Model Content
