Description

Technical Field

[0001] The utility model relates to the technical field of natural plant essential oil extraction, in particular to a highly efficient and energy-saving multi-stage condensation natural plant essential oil extraction and distillation device. Background Art

[0002] Natural plant essential oil is a high-concentration, aromatic, volatile plant essence extracted from the flowers, leaves, peels, barks, rhizomes and other parts of plants; in the extraction process, distillation is one of the most commonly used and effective methods. The basic principle of distillation is to release the aromatic components in the plant in the form of vapor by heating, and then condense the vapor into liquid to obtain essential oil. The distillation process includes four steps: heating, vapor formation, vapor collection and cooling back to liquid; and the condensation equipment is one of the important devices in the extraction.

[0003] In the prior art, common condensing equipment only has a single spiral condensing tube for condensation, and its condensation effect is not ideal; for example, the utility model patent with authorization announcement number CN205133554U discloses an aromatic substance distillation and extraction machine with controllable condensation temperature, which includes a cylinder body, a heating device, a condensing coil, a fan, a cover, a temperature sensor and a control circuit, wherein the heating device is arranged at the bottom of the cylinder body, a sealing cover is arranged at the upper end outlet of the cylinder body, the steam inlet of the condensing coil is connected with the interior of the cylinder body through the sealing cover, and is encapsulated above the sealing cover by the cover, the liquid outlet of the condensing tube is arranged outside the cover, the fan is arranged on the top of the cover, the temperature sensor is located at the outlet of the condensing coil, the signal output end of the temperature sensor is connected to the signal input end of the control circuit, and the control signal output end of the control circuit is connected to the control circuit output end of the fan. The temperature at the outlet of the condensing coil is fed back to the control circuit through the temperature sensor. The control circuit adjusts the air volume of the fan according to the temperature at the outlet, thereby controlling the air volume flowing through the condensing coil and achieving the purpose of controlling the condensing temperature.

[0004] Although the aromatic substance distillation and extraction machine with controllable condensation temperature is convenient for controlling the condensation temperature, the device is only equipped with a single condenser tube during condensation. During the distillation and extraction process, when a large amount of water vapor quickly flows into the condenser tube, its flow rate is too fast, causing part of the water vapor to be quickly discharged before it is fully cooled to a liquefied state. This not only causes a waste of the extract, but also directly affects the efficiency of the overall extraction process. In view of this, we propose an efficient and energy-saving multi-stage condensation natural plant essential oil extraction and distillation device. Utility Model Content

[0033] In this embodiment, guide grooves 231 are provided at both ends of the movable plate 23, two first guide rails 202 are fixed at both sides of the inner top of the fixing frame 20, two second guide rails 212 are fixed at both sides of the top of the base 21, and the guide grooves 231 are slidably connected with the corresponding first guide rails 202 and second guide rails 212. This design guides the horizontal movement of the two movable plates 23, ensuring the stability and smoothness of the movable plates 23.

[0034] In this embodiment, two limiting rings 273 are coaxially fixed to the outer wall of the housing 27, and the clamping groove 241 is clamped between the two limiting rings 273. The setting of the limiting rings 273 allows the clamping plate 24 to be stably clamped between the two limiting rings 273, ensuring the fixing effect of the clamping plate 24 on the housing 27.

[0035] In this embodiment, the front surface of the base 21 is provided with a second notch 211, the front surface of the fixing frame 20 is provided with a first notch 201, and the end of the condenser tube 28 passes through the corresponding first notch 201 and second notch 211.

[0036] In this embodiment, two support plates 213 are fixed to the bottom of the base 21, and the base 21 is fixedly connected to the support plates 213 by bolts. The support plates 213 play a stable supporting role for the entire device, ensuring the stability of the device.

[0037] In this embodiment, the overall shape of the fixing frame 20 is U-shaped, and the fixing frame 20 is fixedly connected to the base 21 by bolts. The bolt fixing method ensures the stability of the fixing frame 20 and the supporting effect of the fixing frame 20 on the housing 27.

[0038] In this embodiment, the still 1 is fixedly connected to the still cover 10 by bolts, and a feed port 11 is installed on the top of the still cover 10.

[0039] In this embodiment, the overall shape of the drain pipe 26 and the water inlet pipe 25 are both L-shaped, and the drain pipe 26 and the water inlet pipe 25 are both made of plastic material.

[0041] It should be added that the overall shape of the condenser tube 28 in this embodiment is spiral, and the condenser tube 28 is a product made of alloy aluminum. The spiral design can increase the contact area between the condenser tube 28 and the water vapor, so that the water vapor can more fully contact the tube wall during the flow in the tube, thereby more effectively exchanging heat. This design also helps to slow down the flow rate of water vapor, allowing the water vapor to stay in the tube longer, further improving the condensation efficiency. The high thermal conductivity of alloy aluminum can quickly transfer the heat in the water vapor to the outside of the tube to achieve rapid condensation.

[0042] It is worth noting that the distillation kettle 1 involved in this embodiment is an existing conventional technology and will not be described in detail here.

[0043] During specific use, the user first puts the raw materials into the distillation kettle 1 through the feed port 11. As the raw materials are heated in the distillation kettle 1, a large amount of steam is generated in the kettle body. The steam also enters the condenser 28 above through the exhaust pipe 12 and moves downward along the condenser 28. At the same time, cooling water enters the shell 27 through the water inlet pipe 25 and the first connecting port 251. During the flow of the water vapor in the condenser 28, it contacts the low-temperature tube wall, and part of the water vapor is quickly cooled and liquefied. Then the water vapor and the extract continue to move downward to the condenser 28 below. At this time, the remaining water vapor is liquefied again in the condenser 28, and finally the extract is discharged to the outside through the bottom of the condenser 28. The user can use a container to hold the extract.

[0044] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
