Description

Technical Field

[0001] This utility model relates to the field of natural fragrance distillation and condensation technology, and in particular to a multi-stage vacuum distillation and condensation device for natural fragrances. Background Technology

[0002] The multi-stage vacuum distillation and condensation unit for natural fragrances is a high-end device specifically designed for the efficient extraction of essential oils from natural fragrances. By combining distillation and vacuum condensation technologies, it achieves low-temperature, high-purity separation, and is especially suitable for extracting fragrances such as jasmine and citrus that are easily oxidized or contain esters.

[0003] A search revealed that patent CN214808510U discloses a multi-stage condenser for vacuum distillation; however, this device has the following shortcomings in use:

[0004] When heating liquids, the first tank is heated by hot water. However, if the heat source is affected by fluctuations (such as heating interruption), it is impossible to continuously supply energy when the heat source is interrupted, and it is difficult to maintain a constant temperature when the heat load changes, which can easily lead to fluctuations in the medium temperature and affect product quality. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where heating liquids involves heating the first tank with hot water. However, if the heat source fluctuates (e.g., heating is interrupted), it is impossible to continuously supply energy when the heat source is interrupted, and it is difficult to maintain a constant temperature when the heat load changes, which easily leads to fluctuations in the medium temperature and affects product quality. Therefore, this invention proposes a multi-stage vacuum distillation and condensation device for natural fragrances.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A multi-stage vacuum distillation and condensation device for natural spices includes a distillation tank, a first tank body, a second tank body, a vacuum pump, a first condenser and a second condenser for condensation. The top of the distillation tank is fixedly provided with an inlet pipe and connected to it. A flange for external connection is welded on the inlet pipe. The bottom of the distillation tank, the first tank body and the second tank body are all fixedly provided with discharge pipes for easy discharge, and valves are installed on the discharge pipes.

[0008] The distillation tank is equipped with a heat storage mechanism, which can provide heat when the heat source is interrupted.

[0009] To reduce environmental pollution caused by the exhaust gases, vacuum pumps also include a treatment mechanism that processes the gases as they are discharged.

[0010] In one possible design, the heat storage mechanism includes a heat storage layer for heat storage and an insulation sleeve for heat preservation. The distillation tank has a cavity, the heat storage layer is filled in the cavity, and the insulation sleeve is fixedly fitted onto the distillation tank.

[0011] In one possible design, the processing mechanism includes a mounting cover and a filter for treating exhaust gas. The bottom of the vacuum pump is fixedly connected to the top of the second tank. A delivery pipe is fixedly installed at the suction port of the vacuum pump, and one end of the delivery pipe is fixedly connected to and communicates with the top of the second tank. An exhaust pipe is fixedly installed at the discharge port of the vacuum pump. An external thread is provided on the outer side of one end of the exhaust pipe. A through hole is provided at one end of the mounting cover, and an internal thread is provided on the inner wall of the mounting cover. The filter is placed inside the mounting cover, and the diameter of the through hole is smaller than the diameter of the filter. The mounting cover is threadedly connected to the exhaust pipe.

[0012] In one possible design, the inlet of the first condenser is fixedly provided with a first pipe, which is fixedly connected to and communicates with the top of the distillation tank; the outlet of the first condenser is fixedly provided with a second pipe, one end of which is fixedly connected to and communicates with the top of the first tank; the inlet of the second condenser is fixedly provided with a third pipe, one end of which is fixedly connected to and communicates with the top of the first tank; and the outlet of the second condenser is fixedly provided with a fourth pipe, one end of which is fixedly connected to and communicates with the top of the second tank.

[0013] In one possible design, a motor is fixedly mounted on the top of the distillation tank, and the output end of the motor passes through the top of the distillation tank. A rotating rod is fixedly mounted on the output end of the motor, and stirring blades for improving the heating effect are welded onto the rotating rod.

[0014] In one possible design, the mounting cover has anti-slip textures to increase friction and prevent slippage.

[0015] In one possible design, the inner wall of the distillation vessel is fixedly provided with a heating element for heating.

[0016] In this application, the natural fragrance raw material (liquid) to be distilled is added into the distillation tank through an inlet pipe. The flange on the inlet pipe can be used to connect to an external feed pipe for continuous addition of raw material. The heating element on the inner wall of the distillation tank is activated to heat the raw material. At the same time, the motor is started to drive the rotor and stirring blades to rotate, ensuring uniform heating of the raw material and improving distillation efficiency. As heating proceeds, the volatile components in the raw material gradually evaporate to form steam. The steam first enters the first condenser for preliminary condensation, and the condensed liquid flows into the first tank. The incompletely condensed steam continues to enter the second condenser for further condensation, and the condensed liquid flows into the second tank. Through multi-stage vacuum distillation, different volatile components in the raw material can be separated more effectively. During the distillation process, a vacuum pump is activated to extract gas from the second tank through a delivery pipe, maintaining a vacuum inside the distillation tank. The vacuum pump discharges gas through a filter in the processing mechanism, reducing environmental pollution. The filter material can be selected based on the odor produced by the fragrance. The insulation jacket can be made of polyurethane, which has good insulation properties. A heat storage layer, which can be one of phase change wax (paraffin wax) or checker bricks, is used. The specific material can be chosen according to actual needs. The heat storage layer and insulation jacket allow for heat storage and utilization, reducing ineffective heat loss and providing backup heat when the heat source is interrupted, ensuring continuous power supply. The heating element can be one of an electric heating plate or an electric heating wire, selected according to actual needs. It should be noted that the heating element and vacuum pump require an external controller and external power supply for operation.

[0017] The beneficial effects of this utility model are as follows:

[0018] In this utility model, the multi-stage vacuum distillation and condensation device for natural spices is designed with a heat storage mechanism inside the distillation tank. This design allows the heat storage layer to release stored heat when the heat source is interrupted, providing a continuous heat supply for the distillation process and ensuring the continuity of distillation.

[0019] In this utility model, the multi-stage vacuum distillation and condensation device for natural fragrances treats the discharged gas through a processing mechanism, a mounting cover, and a filter screen. The material of the filter screen can be selected according to the aroma produced by the fragrance, effectively removing harmful substances from the gas and reducing environmental pollution.

[0020] In this invention, when the heat source is interrupted, the heat storage layer can release the stored heat through the heat storage mechanism, providing a continuous heat supply for the distillation process and ensuring the continuity of distillation. The processing mechanism can effectively remove harmful substances from the gas and reduce environmental pollution. Attached Figure Description
