Description

Technical Field

[0001] The utility model relates to the technical field of separation equipment, and particularly relates to an essential oil distillation device for citrus. Background Art

[0002] Essential oils are natural products. Among them, citrus essential oils exist in the oil gland cells of citrus peels and are a widely used plant essential oil. Since the steam distillation method is simple and convenient, no other components are introduced during the extraction process, and the product purity is high, the steam distillation method is the main extraction method for citrus essential oils. The steam distillation method places the raw materials on the sieve plate in the distillation pot, and a certain amount of water is placed under the sieve plate to generate enough saturated steam required for the distillation operation. The essential oil in the raw materials is steamed out and extracted by the steam. The existing distillation equipment has the following problems: If a large amount of raw materials are put in for a single distillation, due to the mutual stacking of the raw materials, the steam is not easy to penetrate the raw materials inside, so a longer distillation time is required to effectively utilize the raw materials, resulting in higher energy consumption; If only a small amount of raw materials are put in each time, the utilization rate of the raw materials in a single distillation can be significantly improved by spreading them out, but the raw materials need to be frequently replaced, resulting in low production efficiency. To solve the above problems, this case is proposed. Content of the Utility Model

[0035] The following further describes this application with a specific working process:

[0036] Distillation process: Lay the citrus peel as the raw material on the sieve tray 2, and place each sieve tray 2 into the distillation box 1 through the feeding port 12 and place them on each partition shelf layer 11; Rotate the closing door 13 to close the feeding port 12 and position it in the closed state through the positioning mechanism 132. At this time, the inside of the distillation box 1 is in a relatively closed state. The water inlet pipe 16 injects a certain amount of clear water into the distillation box 1; The heating assembly 3 works, and the electric heater 31 heats the clear water to generate water vapor. The water vapor passes upward through the raw materials on each sieve tray 2 to distill and extract the essential oil.

The cooling water enters and exits the cooler 4 through the circulating water inlet 44 and the circulating water outlet 45. Under the cooling effect of the cooling water in the cooler 4, the water vapor condenses into a liquid oil-water mixture and is sent out from the discharge port 42. The oil-water mixture enters the oil-water collector 5. After the distillation is completed and left standing for a period of time, due to the different densities of oil and water, the essential oil floats on the upper layer and the hydrosol is on the lower layer. Therefore, the essential oil is mainly in the essential oil tank 51 and the hydrosol is mainly in the hydrosol tank 53. By adaptively opening and closing the first outlet valve 522 and the second outlet valve 532 and adjusting the oil-water boundary line to be at the transparent tube 52 for easy observation, the essential oil can be obtained through the essential oil outlet 521 and the hydrosol can be obtained through the hydrosol outlet 531.

[0037] Replacing raw materials: When most of the essential oil in the raw materials in the distillation box 1 has been distilled and extracted, the raw materials need to be replaced. Open the pressure relief valve 141 to reduce the pressure in the distillation box 1 to a safe value close to the room pressure, open the positioning mechanism 132 and rotate the closing door 13 to open the feeding port 12, and use tools to hook the first handle 23 to pull out each sieve tray 2 and take it out from the feeding port 12; Then push each sieve tray 2 laid with new raw materials into each partition shelf layer 11 from the feeding port 12, rotate the closing door 13 to close the feeding port 12 and position it in the closed state through the positioning mechanism 132, and carry out the next round of distillation process.

[0038] The above is only a specific implementation manner of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantive modification made to the present utility model using this concept shall fall within the scope of infringement of the protection scope of the present utility model.
