Problems solved by technology

However, it has not set foot in the pharmaceutical industry so far. The main reason is that pharmaceutical companies do not know enough about thermal oil furnaces, do not understand the characteristics of high efficiency, energy saving, safety and stability of thermal oil furnaces, worry that the leakage of heat transfer oil will affect the quality of medicines, and have never had A precedent for the use of hot oil furnaces in pharmaceutical companies
Therefore, hot oil furnaces have not been used in the pharmaceutical industry.

Embodiment 1

[0056] 1. Application of heat conduction oil heating process in the extraction and production process of active ingredients of traditional Chinese medicine:

[0057] First to 3.5m 3 The multifunctional extraction tank is inspected for appearance, and then the airtightness test is carried out. Under the condition of ensuring no leakage, conduct cold cycle after injecting heat transfer oil. Add 300kg of medicinal materials into the tank and inject 3000kg of water. The hot oil furnace starts heating, and the heating time and temperature are recorded.

[0058] Heat the extraction tank to boiling. After the liquid medicine boils, according to the requirements of the pharmaceutical production process, the liquid medicine needs to be kept at a slight boil for more than 2 hours after boiling, because there is still heat transfer oil at about 160°C circulating in the interlayer of the extraction tank. , so the thermal oil furnace basically does not need to be heated during this time...

Embodiment 2

[0062] 2. Application of heat conduction oil heating process in the concentrated production process of active ingredients of traditional Chinese medicine:

[0063] first to 2m 3 Vacuum concentration tank for visual inspection, and then conduct air tightness test. Under the condition of ensuring no leakage, conduct cold cycle after injecting heat transfer oil. The hot oil furnace starts to supply heat. After the temperature reaches the requirement, turn on the vacuum pump, add 300L liquid medicine into the vacuum tank, start to concentrate, and record the heating time and temperature.

[0064] heating method

Embodiment 3

[0066] 3. Application of heat conduction oil heating process in the drying production process of active ingredients of traditional Chinese medicine:

[0067] The vacuum drying oven is used to dry the ointment. The initial moisture content of the ointment is 60%, and it is required to reach a moisture content of less than 2% after drying, which is basically dry. Since the ointment contains some heat-sensitive substances, too high a drying temperature will destroy the medicinal properties of the heat-sensitive substances. It is required that the maximum temperature of the heat-conducting oil passed into the drying box should not exceed 130°C. The temperature of the heat transfer oil is 115°C, and the return oil temperature is set at 95°C.

Abstract

The invention relates to a heating process technology of the pharmaceutical field, in particular to Application of heating heat-conducting oil in processes of extracting, concentrating and drying Chinese medicine effective components. The heat-conducting oil heating process comprises a hot oil circulation loop and a cold oil circulation loop, can realize that three single structure units of extraction, concentration and dryness can be heated in production and multiple structure units can be heated at the same time; a cooling circulation loop is additionally arranged in a heating system for safe operation and production efficiency increase, and cold oil is directly transmitted into an interlayer of an extraction pot through a high-temperature gear pump in a lower pot in order to replace hot oil into the lower pot. The invention has the advantages of high temperature, low pressure, closed-loop circulation, high heat efficiency, good energy saving effect, smooth operation, and the like.

Description

technical field [0001] The invention relates to a heating process technology in the field of pharmacy, in particular to the application of heat conduction oil heating in the extraction, concentration and drying process of active ingredients of traditional Chinese medicine. Background technique [0002] In the large-scale production process of traditional Chinese medicine extraction, concentration and drying, the traditional heating medium is water vapor. The main problems are high working pressure, high requirements for equipment safety, slow heat transfer, low efficiency and high energy consumption. [0003] Thermal oil furnace is also called organic heat carrier boiler, that is, the working medium in the boiler is heat transfer oil instead of water and steam. The heat-conducting oil is heated in the boiler to obtain high temperature, and the high-temperature heat-conducting oil is transported to the heat-consuming equipment by the circulating heat oil pump, and then sent b...
