Description

Technical Field

[0001] This utility model relates to the field of orange blossom essential oil extraction technology, specifically to an orange blossom essential oil extraction and separation device. Background Technology

[0002] Orange blossom essential oil is a natural fragrance widely used in high-end perfumes and cosmetics. Due to its high value, the yield and purity during extraction are crucial. Currently, the most common industrial method for extracting orange blossom essential oil is steam distillation. This method first distills the orange blossom raw material in a distillation kettle, then introduces the mixed steam rich in essential oil components into a condenser to convert it into a gas-liquid mixture. Finally, this mixture is passed through an oil-water separator for separation, thus obtaining orange blossom essential oil and its byproduct, orange blossom hydrosol.

[0003] In this process, the oil-water separator is the core device that directly affects the quality and yield of essential oils. Currently, the oil-water separation devices commonly used in the industry mainly suffer from the following inherent defects: 1. The separation principle is primitive and inefficient: Most existing separators are simple hollow tanks, and their separation process relies entirely on the inherent density difference between essential oils and water for natural gravity settling. This passive settling method takes a long time and is insufficient for micron-sized oil droplets, causing them to fail to float completely and remain in the hydrosol in large quantities, resulting in a significant loss of essential oil yield.

[0004] 2. Simple internal structure, unable to promote separation: Traditional separation tanks lack any optimized structure designed to improve separation efficiency. The flow rate drops sharply after the mixture enters, and the aggregation of oil droplets relies entirely on accidental collisions, a slow and incomplete process. This leads to incomplete separation, potentially introducing water into the essential oil product, affecting its purity. Furthermore, the essential oil residue in the hydrosol reduces the value of the byproduct.

[0005] 3. Low level of automation and reliance on manual experience: The entire separation process heavily depends on the experience of the operators. Workers need to constantly observe changes in the oil-water interface inside the tank and manually adjust the valves at the outlets of the essential oil and hydrosol. This manual operation mode is not only time-consuming and labor-intensive, increasing labor costs, but also highly susceptible to errors in judgment or operational delays, leading to the hydrosol mixing with the essential oil or the essential oil being lost with the hydrosol. This results in unstable product quality and makes continuous, large-scale production impossible.

[0006] 4. Unclear functional areas and lack of design optimization: Traditional separators are treated as a single hollow cavity, without functional area division or proportional optimization of their internal space. This leads to interference between the settling space, separation space, and collection space, failing to create a stable and efficient environment for complete oil-water separation.

[0007] Therefore, we propose an orange blossom essential oil extraction and separation device. Utility Model Content

[0008] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides an orange blossom essential oil extraction and separation device. By setting an inclined guide plate and coalescing packing in the working area, passive sedimentation is transformed into active polymerization, effectively separating micron-sized oil droplets. Through functional zone division and overflow outlet design, the device improves the efficiency and purity of essential oil extraction and achieves continuous production, effectively solving the problems in the background technology.

[0009] (II) Technical Solution To achieve the above objectives, the technical solution adopted by this utility model is as follows: an orange blossom essential oil extraction and separation device, comprising a tank, wherein the upper side wall of the tank is provided with a mixed liquid inlet, the top is provided with an essential oil outlet, and the bottom is provided with a pure dew outlet. Inside the tank, from top to bottom, there are interconnected essential oil collection area, working area, and pure dew area, with the volume ratio of the three areas occupying the effective height of the tank being: pure dew area 10%-25%, working area 60%-80%, and essential oil collection area 10%-20%. The working area is provided with multiple independent guide plates, which are fixed to the inner wall of the tank. The guide plates are alternately arranged tilted to the left and right, with an angle of 45° to 60° with the horizontal plane, and their surfaces are rough or hydrophobic. A pressing net is fixedly installed at the upper part of the working area, and a supporting net is fixedly installed at the lower end of the working area. The space between the lower end of the pressing net and the supporting net is filled with coalescing filler. A valve is installed in the pure dew outlet.

[0010] Preferably, the mixture inlet is located at the top of the working area.

[0011] Preferably, the essential oil outlet is an overflow pipe structure, and the height of its opening is higher than the height of the mixture inlet.

[0012] Preferably, the coalescing filler is stainless steel wire mesh or polytetrafluoroethylene fiber.

[0013] Preferably, gaps are left between the guide plates in each group to form a channel for the flow of pure dew.

[0014] (III) Beneficial Effects Compared with the prior art, this utility model provides an orange blossom essential oil extraction and separation device, which has the following beneficial effects: 1. This neroli essential oil extraction and separation device transforms the traditional "passive natural sedimentation" into "active induced polymerization" by setting an inclined guide plate and an oleophilic and hydrophobic coalescing packing in the working area of ​​the oil-water separator. When the mixture flows through the tortuous flow channel, the flow velocity and direction change frequently, increasing the probability of collision between oil droplets. At the same time, the oleophilic packing can efficiently capture micron-sized oil droplets and coalesce them into larger oil droplets, thereby accelerating their floating. This combined effect fundamentally solves the problem of the difficulty in separating tiny oil droplets, making the essential oil separation more thorough, improving the extraction yield of essential oil, and reducing value loss.

[0015] 2. This neroli essential oil extraction and separation device clearly defines an "essential oil collection zone" and a "hydrosol zone," and with an overflow pipe-type essential oil outlet located at the top, it ensures that only the purest essential oil from the top layer can be collected. This structure physically prevents hydrosol from mixing into the essential oil product. At the same time, the stable internal flow field avoids back-mixing during the separation process, thus ensuring that the final neroli essential oil has higher purity and more stable quality.

[0016] 3. This orange blossom essential oil extraction and separation device automatically collects the essential oil through an overflow pipe, eliminating the need for constant manual observation and valve operation. This automates the separation process, reducing labor costs and operational intensity. Furthermore, the stable functional area design provides a foundation for continuous feeding and discharge, breaking the bottleneck of traditional intermittent production and resulting in a significant leap in production efficiency.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figure 1-3As shown, this utility model provides a technical solution: an orange blossom essential oil extraction and separation device.

[0023] In this embodiment, the orange blossom essential oil extraction and separation device includes a vertical cylindrical tank 1. The internal space of the tank 1 is clearly divided into three interconnected functional areas from top to bottom: an essential oil collection area 10, a working area 11, and a hydrosol area 12. The preferred volume ratio of these three areas within the effective height of the tank is: hydrosol area 12 15%, working area 11 70%, and essential oil collection area 10 15%. This proportional allocation ensures sufficient working area space for thorough separation, while the collection areas for essential oil and hydrosol are also appropriately sized.

[0024] The tank 1 has an essential oil outlet 2 at its top center. This outlet is designed as an overflow pipe structure, higher than the mixture inlet 5, ensuring that only the uppermost, purest essential oil overflows and is collected. The tank 1 also has a hydrosol outlet 3 at its bottom center, with a valve 4 installed on the outlet pipe to control the discharge of hydrosol. The upper side wall of the tank 1, specifically at the top of the working area 11, has a mixture inlet 5 for introducing an oil-water mixture from the condenser.

[0025] Two key components are installed within the core working area 11 to enhance the separation process. The first component consists of multiple independent baffles 9, which are alternately fixed to the inner wall of the tank 1 (i.e., one tilts to the left, and the next adjacent one tilts to the right). These baffles 9 are set at a 50° angle to the horizontal plane, and their surfaces are treated with a hydrophobic coating (e.g., sprayed with a polytetrafluoroethylene coating) to form a rough or hydrophobic surface. Gaps are left between adjacent baffles 9, forming channels for the liquid to flow downwards in a tortuous manner.

[0026] The second component is the coalescing packing 8, which is filled in the working area 11. This coalescing packing 8 is made of stacked oleophilic and hydrophobic polytetrafluoroethylene fibers, and its upper and lower ends are respectively fixed by a compression mesh 6 and a support mesh 7 to prevent the packing from loosening or flowing with the liquid. The support mesh 7 is fixed at the lower end of the working area 11, and the compression mesh 6 is fixed at the upper part of the working area 11.

[0027] The working principle of this utility model is as follows: The mixture of neroli essential oil and water from the condenser enters the working area 11 of the device through the mixture inlet 5. Upon encountering the first guide plate 9, its flow direction changes, and the flow velocity is redistributed. As it flows through the tortuous flow channel formed by multiple alternating inclined guide plates 9, the flow direction and velocity of the mixture continue to change, increasing the probability of collisions and coalescence between the dispersed oil droplets.

[0028] Simultaneously, the mixture permeates through the coalescing packing 8 filling the working area 11. Due to the excellent oleophilic and hydrophobic properties of the coalescing packing 8, micron-sized and smaller oil droplets are captured and adhered to the packing fibers. These captured fine oil droplets continuously coalesce inside the packing, eventually forming sufficiently large oil droplets. When the oil droplets become large enough that their buoyancy is sufficient to overcome the drag force of the water flow and the adsorption force of the packing, they detach from the packing and float to the top of the tank.

[0029] Under the combined action of the flow guide plate and the coalescing packing, essential oil droplets are efficiently separated from the aqueous phase and aggregated to a larger size. The less dense essential oils rise rapidly and eventually accumulate in the top essential oil collection area 10. When the essential oil level in collection area 10 exceeds the height of the essential oil outlet 2 (overflow pipe), the pure essential oil will automatically overflow and be collected. The denser aqueous phase (i.e., neroli hydrosol) flows under gravity, passing through the channel formed by the flow guide plate 9 and the support net 7, and sinks to the bottom hydrosol area 12 for temporary storage. Operators can open the valve 4 of the hydrosol outlet 3 as needed, depending on the liquid level, to discharge and collect the hydrosol.
