Description

Technical Field

[0001] This utility model relates to the field of vacuum concentration technology, and in particular to a vacuum concentration device for hesperidin from Citrus aurantium. Background Technology

[0002] In the field of extraction and purification of effective components from traditional Chinese medicine, vacuum concentration technology is widely used in the processing of natural products such as hesperidin from immature bitter orange because it can concentrate solutions at low temperatures and avoid damage to heat-sensitive components. However, existing vacuum concentration devices have the following shortcomings in practical applications:

[0003] Traditional equipment often employs a decentralized layout, with core components such as the concentration pot, condensation system, and thermal management unit independently located. This results in large floor space, low space utilization, complex piping connections between components, and cumbersome operating procedures, increasing energy consumption and maintenance costs during production. In most units, the heating and condensation systems are relatively independent, failing to effectively recover and utilize waste heat generated by steam, leading to significant energy waste. This problem is particularly pronounced in large-scale production, not only increasing production costs but also contradicting current industrial development trends focused on energy conservation and emission reduction. Traditional equipment relies heavily on manual operation for monitoring and controlling key parameters such as pressure and temperature during the concentration process, resulting in poor real-time performance and accuracy. This leads to insufficient stability in the concentration process, making it prone to localized overheating or excessive pressure fluctuations, affecting the extraction purity and yield of hesperidin and failing to meet the requirements of high-quality production.

[0004] Some units have relatively simple safety protection measures, lacking effective overpressure protection and abnormal temperature early warning mechanisms, posing certain safety hazards during equipment operation and potentially leading to equipment damage or even production accidents. The structural design of traditional units has deficiencies in cleaning and maintenance, making waste removal and internal component inspection difficult, increasing downtime for maintenance, affecting production efficiency, and potentially causing product contamination due to incomplete cleaning.

[0005] In summary, the shortcomings of existing vacuum concentration devices in terms of integration, thermal efficiency, process control, safety, and ease of maintenance restrict the efficient extraction and purification of heat-sensitive components such as hesperidin from immature bitter orange. There is an urgent need to develop a vacuum concentration device with high integration, good thermal efficiency, precise control, safety, reliability, and ease of maintenance. Therefore, this paper proposes a vacuum concentration device for hesperidin from immature bitter orange. Utility Model Content

[0031] Working principle: The working process of this device is centered on the integrated box 1. Through the coordinated operation of various components, the vacuum concentration of hesperidin from immature bitter orange is achieved. The specific principle is as follows:

[0032] Material injection and pretreatment: The hesperidin solution to be concentrated is injected into the concentration pot 2 through the injection port 5. At the same time, an appropriate amount of solvent is added into the concentration pot 2 through the water inlet control valve 3 and the water inlet pipe 4 to prepare for the concentration process.

[0033] Heating and vacuum concentration process:

[0034] The heating element of the thermal management unit 22 directly heats the concentrate 2, and the heat source delivery pipe conducts heat to the inside of the concentrate 2, causing the solution to heat up.

[0035] The steam chamber 6 is wrapped around the outer surface of the concentrator 2, absorbs the heat generated by heating and generates steam, which enters the condenser 9 in the condensation chamber 8 through the steam pipe 7.

[0036] The device creates a reduced pressure environment, lowering the boiling point of the solution and causing the solvent to evaporate at low temperatures, thus preventing the hesperidin from being deactivated by high temperatures.

[0037] Stirring and uniform heating control: The stirring motor 15 drives the stirring rod in the concentration pot 2 to rotate, ensuring that the solution is heated evenly and preventing local overheating from destroying the effective ingredients.

[0038] Steam condensation and solvent recovery:

[0039] The steam is cooled and liquefied in the condenser 9 by the cooling water introduced through the cooling water pipe 10, and the liquefied solvent flows into the storage tank 16 through the liquid delivery pipe 17 for storage.

[0040] Wastewater generated by condensation is discharged through drain pipe 23.

[0041] Real-time monitoring of pressure and temperature:

[0042] Pressure gauge 11 and temperature gauge 12 monitor the pressure and temperature inside the concentration pot 2 in real time and transmit the data to the main control unit 20.

[0043] When the pressure exceeds the threshold, the main control unit 20 controls the safety valve 13 and the pressure relief valve 14 to open in sequence to relieve pressure and ensure equipment safety.

[0044] The main control unit 20 adjusts the heating power of the thermal management unit 22 according to the temperature data to maintain a stable concentration temperature.

[0045] Concentrate discharge and waste residue treatment: After concentration, the concentrate in the storage tank 16 is discharged through the discharge pipe 24; the waste residue in the concentration pot 2 is discharged through the slag discharge port 26; the front cover plate 18 can be removed for internal maintenance of the equipment.

[0046] Waste heat recovery and utilization: The heat exchanger 21 is linked with the thermal management unit 22 to recover the waste heat generated by the steam chamber 6 and use it for the heating process, thereby reducing energy consumption.

[0047] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings.

Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
