Description

Technical Field

[0001] This utility model relates to the field of pepper processing technology, specifically a distillation device for pepper oil extraction. Background Technology

[0002] The main components of Sichuan pepper oil are volatile aromatic substances such as terpenes, alcohols, and esters, whose boiling points are usually lower than those of water or other non-volatile components such as pigments, waxes, and macromolecular fatty acids. During the distillation process, the volatile components are vaporized together with water vapor by heating, and then separated by condensation, which can efficiently extract the target substances, while the non-volatile impurities remain in the distillation residue.

[0003] Existing Sichuan pepper oil distillation equipment suffers from insufficient contact between the Sichuan pepper raw material and water vapor, resulting in incomplete extraction of the volatile oil and low raw material utilization, which affects the yield and quality of the Sichuan pepper oil. Furthermore, in the condensation stage, existing equipment fails to effectively recover and utilize the heat generated during condensation, further reducing overall energy efficiency and causing energy waste. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides the following technical solution: a distillation apparatus for extracting and producing Sichuan pepper oil, comprising:

[0005] Base;

[0006] The distillation unit is placed on the base. The distillation unit includes a distillation shell, a heating water tank at the bottom of the distillation shell, a heating rod inside the heating water tank, and a water inlet at the top of the heating water tank. A support plate is detachably installed inside the distillation shell. A distillation fan blade is rotatably installed on the support plate. A stirring blade is fixedly installed at the other end of the distillation fan blade. The stirring blade extends into the inside of the support plate. Multiple vent holes are provided on the support plate.

[0007] The condenser is located on one side of the distillation unit and is detachably connected to the distillation housing via a distillation conical housing. A distillation tube is rotatably mounted on the distillation conical housing, and the other end of the distillation tube is connected to the condenser tube, which is located inside the condenser housing.

[0008] Furthermore, a conical seat is fixedly provided at the bottom of the condenser shell, and a drain valve is rotatably provided on the conical seat.

[0009] Furthermore, a drain outlet is fixedly provided at the bottom of the condenser housing, and a water inlet is fixedly provided at the top of the condenser housing.

[0010] Furthermore, the condenser tubes are arranged in a circular array along the rotation center of the condenser shell, and the condenser tubes are made of copper.

[0011] Furthermore, the drain outlet is detachably connected to the inlet one via a conduit, and the inlet one is equipped with a solenoid valve.

[0012] Furthermore, the heating rod is fixedly mounted on the heating fixing plate, and the heating fixing plate and the heating rod are electrically connected.

[0013] The advantages of this utility model compared with the prior art are:

[0014] 1. Enhanced contact between water vapor and Sichuan peppercorns: The device incorporates distillation fan blades and stirring blades. The impact force of water vapor drives the fan blades to rotate, which in turn drives the stirring blades to continuously agitate the Sichuan peppercorns in the tray. This design ensures that the Sichuan peppercorns continuously tumble during distillation, ensuring ample contact with the water vapor. This avoids the problem of insufficient contact caused by peppercorn accumulation in traditional devices, effectively promoting the vaporization of volatile oils and improving extraction efficiency.

[0015] 2. Optimized structure for pepper placement and steam circulation: The support tray has ventilation holes with a diameter smaller than the peppercorns, which can both hold the peppercorns and ensure that water vapor passes evenly through the peppercorn layer. At the same time, the cylindrical structure in the middle and conical structure at the bottom of the distillation shell is conducive to the even upward diffusion of water vapor, further ensuring full contact between the peppercorns and water vapor, so that the volatile oil is fully extracted and the utilization rate of raw materials is improved.

[0016] 3. Condensation Heat Recovery and Utilization: In the condensation stage, the high-temperature mixed steam inside the condenser tube exchanges heat with the water inside the condenser shell, raising the temperature of the condensate. When the heating water tank needs replenishment, the heated condensate is added to the heating water tank through the connection between the drain outlet and the inlet, reducing the heat consumption required for the water in the heating water tank to rise from room temperature to boiling point, reducing energy waste, improving energy utilization, avoiding ineffective energy loss, realizing energy recycling, and meeting the requirements of energy conservation and emission reduction.

[0027] like Figures 1 to 7As shown, the distillation unit 1 is mounted on the base 3.

The heating rod 106 is installed inside the heating water tank 104 to heat the water inside the heating water tank 104, causing the water to turn into water vapor. The water inlet 105 is located at the top of the heating water tank 104. The middle part of the distillation shell 100 is cylindrical, and the bottom is round. The conical distillation shell 100 has a detachable support plate 103 inside via a groove on the shell. The support plate 103 has multiple vent holes, the diameter of which is smaller than the diameter of the peppercorns. A distillation fan blade 101 is rotatably mounted at the center of the support plate 103. A stirring blade 102 is fixedly mounted at the other end of the distillation fan blade 101. The stirring blade 102 extends into the support plate 103 to stir the peppercorns inside the support plate 103. A heating rod 106 is fixedly mounted on a heating plate 107. A resistance heating wire is installed inside the heating rod 106 and is electrically connected to a socket on the heating plate 107.

[0028] like Figures 1 to 7 As shown, the condenser 2 is located on one side of the distillation unit 1 and is detachably connected to the distillation housing 100 via a distillation conical housing 200. The inner wall of the distillation conical housing 200 has an internal thread, which engages with the external thread on the top outer wall of the distillation housing 100 to achieve a detachable connection. The condenser 2 includes a distillation conical housing 200, a distillation tube 201, a condenser tube 202, a condenser housing 203, a second water inlet 204, a drain outlet 205, a conical seat 206, and a drain valve 207. The distillation tube 201 is rotatably mounted on the distillation conical housing 200, and the other end of the distillation tube 201 is connected to the condenser tube 202 via a cylindrical connector. The condenser tube 202 is located inside the condenser housing 203. A conical seat 206 is fixedly mounted at the bottom of the condenser housing 203, and a drain valve 207 is rotatably mounted on the conical seat 206. A drain outlet 205 is fixedly mounted at the bottom of the condenser housing 203, and a second water inlet 204 is fixedly mounted at the top of the condenser housing 203. The condenser tubes 202 are arranged in a circular array along the rotation center of the condenser shell 203, and the condenser tubes 202 are made of copper. The drain port 205 is detachably connected to the water inlet 105 via a conduit, and a solenoid valve is installed on the water inlet 105.

[0029] like Figures 1 to 7As shown, the distillation shell 100, distillation fan blades 101, stirring blades 102, support plate 103, heating water tank 104, water inlet 105, heating rod 106, distillation conical shell 200, condenser shell 203, water inlet 204, drain 205, and conical seat 206 are all made of food-grade stainless steel. The distillation tube 201 is made of high-temperature resistant food-grade silicone rubber.

[0030] like Figures 1 to 7 As shown, the distillation apparatus for extracting Sichuan pepper oil disclosed in this utility model has the following working principle:

[0031] Remove the distillation conical shell 200 from the distillation shell 100. Pull out the distillation fan blade 101, stirring blade 102, and support plate 103 together from the distillation shell 100. Place the peppercorns into the support plate 103. Then, re-pass the distillation fan blade 101, stirring blade 102, and support plate 103 through the groove on the distillation shell 100 and install the support plate 103 back into the distillation shell 100. Reinstall the distillation conical shell 200 back onto the distillation shell 100. Connect the second water inlet 204 to the tap water pipe. Fill the condenser shell 203 with water. Then, open the solenoid valve on the first water inlet 105 to inject a certain amount of tap water into the heating water tank 104. After the heating water tank 104 is filled with water, close the solenoid valve.

[0032] Connect the power supply to the socket on the heating plate 107. The resistance wire inside the heating rod 106 generates heat, boiling the water in the heating tank 104 to produce steam. The steam enters the distillation shell 100 and, through the vent on the support plate 103, vaporizes the volatile oil in the peppercorns on the support plate 103 along with the steam, forming a mixed steam. The mixed steam enters the condenser tube 202 from the distillation tube 201, where it comes into contact with the cooler water in the condenser shell 203 and is cooled, re-liquefying to form an "oil-water mixture." Under gravity, this mixture is discharged from the condenser tube 202 and collected in the conical seat 206. Finally, the operator opens the drain valve 207 to complete the collection of the "oil-water mixture," thus completing the entire distillation operation. During the distillation process, when pressurized steam passes through the distillation fan blade 101, the impact force of the steam is converted into mechanical energy that drives the fan blade 101 to rotate. The rotation of the distillation fan blade 101 drives the stirring blade 102 to rotate. The stirring blade 102 stirs the peppercorns in the support plate 103, so that the peppercorns come into uniform contact with the steam, thereby achieving full distillation of the volatile oil of the peppercorns and improving the utilization rate of the raw materials.

[0033] During the condensation process, the high-temperature mixed steam in the condenser tube 202 exchanges heat with the water in the condenser shell 203, causing the water temperature in the condenser shell 203 to rise. When the water level in the heating water tank 104 drops and water needs to be added, the solenoid valve is opened to add the heated water to the heating water tank 104, reducing the energy required for water evaporation, achieving energy saving and emission reduction, and improving energy utilization.
