Slag discharge pumps 66 are respectively provided on the first slag discharge pipe 6 and the second slag discharge pipe 62. A first slag discharge control valve is provided at the output end of the first slag discharge pipe 6 at the slag discharge pump 66. 61. The second slag discharge pipe 62 is provided with a second slag discharge control valve 63 at the output end of the slag discharge pump 66.

[0022] like Figure 1As shown, the cooling discharge device includes a primary condenser 3. The feed end of the primary condenser 3 is connected to a condensing feed pipe 31. The primary condensers 3 of the two cooling discharge devices are respectively connected to the gas outlets at the top of the first rotary cone distillation column 1 and the second rotary cone distillation column 2 via condensing feed pipes 31. The discharge end of the primary condenser 3 is respectively connected to a secondary condenser 32 and an oil-liquid separator 33 via a condensing discharge pipe 314. A regulating valve 34 is installed on the condensing discharge pipe 314 between the feed end of the secondary condenser 32 and the feed end of the oil-liquid separator 33. The secondary condenser 32... The discharge end is connected to the inlet end of the oil separator 33. The discharge end of the oil separator 33 is connected to the aroma extract discharge pump 312 through the finished product discharge pipe 35. The finished product discharge pipe 35 is equipped with a discharge valve 36. The finished product discharge pipe 35 is connected to a gas-liquid separator 37 between the discharge valve 36 and the oil separator 33. The discharge end of the gas-liquid separator 37 is connected to the finished product discharge pipe 35 between the discharge valve 36 and the aroma extract discharge pump 312 through a discharge pipe 38. The inlet and outlet ends of the aroma extract discharge pump 312 are respectively equipped with finished product control valves 313. The discharge pipe 38 is equipped with a discharge valve 39. A bypass pipe 310 is connected between the discharge valve 39 and the gas-liquid separator 37 on the discharge pipe 38 and between the finished product control valve 313 on the finished product discharge pipe 35 and the inlet end of the aroma extract discharge pump 312. An FTC sensor 311 is installed on the bypass pipe 310.

[0023] The high-temperature aroma vapor distilled from the first rotary cone distillation column 1 and the second rotary cone distillation column 2 enters the respective connected cooling and discharge devices through the condenser feed pipe 31. It is first cooled by the primary condenser 3, and then discharged through the condenser discharge pipe 314. The control valve 34 is opened, and the condensed liquid can enter the oil-liquid separator 33 for separation. The discharge valve 36 is closed, and the discharge valve 39 is opened. The aroma extract after separation by the oil-liquid separator 33 enters the gas-liquid separator 37 for further cooling and separation. The obtained aroma extract enters the finished product discharge pipe 35 through the discharge pipe 38 and is output to the finished product tank by the aroma extract discharge pump 312. The FTC sensor 311 on the bypass pipe 310 detects the working status of the gas-liquid separator 37 and controls the discharge of the gas-liquid separator 37 through the discharge valve 39. The liquid material after primary cooling by the primary condenser 3 can be further cooled by the secondary condenser 32 before entering the oil-liquid separator 33 to improve the condensation effect; the aroma extract after separation by the oil-liquid separator 33 can also be directly transported to the aroma extract discharge pump 312 through the discharge valve 36 and then output to the finished product tank.

[0024] The primary condenser 3 and the gas-liquid separator 37 are each connected to a vacuum pump 8 via a high-pressure gas pipe 81. An intake control valve 82 is installed on the high-pressure gas pipe 81 at the inlet end of both the primary condenser 3 and the gas-liquid separator 37. The vacuum pump 8 system provides a vacuum cooling environment for the primary condenser 3 and the gas-liquid separator 37, which can meet the purpose of extracting volatile components at low temperatures and avoid the decomposition of components and changes in flavor caused by temperature in heat-sensitive products.

[0025] Among them, such as Figure 2As shown, the first rotary cone distillation column 1 and the second rotary cone distillation column 2 have the same structure, both including a column body 7. The top of the column body 7 is provided with a feed inlet connected to each feed pipe and a gas outlet connected to the condenser feed pipe 31. The bottom is provided with a slag discharge port connected to each slag discharge pipe. An interlayer 77 is provided on the outer side of the bottom of the column body 7, connecting a steam supply device and the inner cavity of the column body 7. A steam inlet and a steam outlet are respectively provided on the interlayer 77. The steam inlet and steam outlet are respectively connected to a steam generation system via steam pipes 83 to provide high-temperature steam to the rotary cone distillation column. Steam valves 84 are respectively provided on the steam pipes 83 for controlling the steam delivery. A rotating shaft 71 is vertically arranged inside the column body 7. An inverted movable cone 72 is arranged sequentially at intervals along the axial direction on the rotating shaft 71. An inverted fixed cone 73 is arranged sequentially at intervals on the inner wall of the tower body 7. Both the movable cone 72 and the fixed cone 73 can be formed by plates surrounding an inverted conical cavity. The rotating shaft 71 passes through the conical cavity of the movable cone 72 and connects to its bottom. The periphery of the fixed cone 73 is connected to the inner wall. The movable cone 72 and the fixed cone 73 are spaced apart and staggered. A crushing plate 74 is vertically distributed on the inner wall of the tower body 7 between two adjacent fixed cones 73. The lower end of the rotating shaft 71 extends out of the tower body 7 and is connected to a drive device 75, such as a rotary motor. The rotary motor is connected to the rotating shaft 71 through a speed change mechanism. Material enters the tower body 7 through the feed inlet. The drive device 75 drives the rotating shaft 71 to rotate the moving cone 72. Under centrifugal force, the material is thrown outward and upward along the upper surface of the moving cone 72 to form a liquid film. After the liquid film is crushed by contact with the crushing plate 74, it flows back along the upper side of the lower fixed cone 73 to the upper side of the next layer of moving cone 72 and continues to be centrifugally thrown out by the rotating moving cone 72 to form a liquid film. In this way, the material flows downward from the upper part of the tower body 7 layer by layer through the gap between the moving cone 72 and the fixed cone 73. At the same time, the high temperature steam supplied by the steam supply device flows upward from the bottom of the tower body 7, passes over the surface of the liquid film, and collects volatile components during the upward process, thus achieving the purpose of extraction. The liquid film thrown out by the moving cone 72 is broken by the crushing plate 74 and flows from top to bottom layer by layer, increasing the product flow distance. Blades 76 can be set at the outer edge of all moving cones 72. The rotating blades generate extremely high disturbance to the rising steam flow. The high-speed disturbance, the undulating liquid film, and the longer steam and liquid path length enable volatile components to be efficiently transferred from the liquid to the steam flow, increasing the contact area with high-temperature steam and thus improving the extraction efficiency.This utility model can also be equipped with a cleaning system to clean the first rotary cone distillation column 1, the second rotary cone distillation column 2, the first feed pipe 5, the second feed pipe 52, and the two primary condensers 3. The cleaning system includes a soft water supply system that is connected to the first rotary cone distillation column 1 and the second rotary cone distillation column 2 through soft water pipes 9. Soft water control valves 91 are respectively installed on the soft water pipes 9. Distillation cleaning control valves 92 are respectively installed on the two soft water pipes 9 between the soft water control valves 91 and the first rotary cone distillation column 1 and the second rotary cone distillation column 2. Condensation cleaning pipes 93 connecting the two primary condensers 3 are respectively installed on the soft water pipes 92 and 91. Condensation cleaning control valves 94 are respectively installed on the condensation cleaning pipes 93. Feed cleaning pipes 95 connecting the first feed pipe 5 and the second feed pipe 52 are also respectively installed on the soft water pipes 92 and 91. Feed cleaning control valves 96 are respectively installed on the feed cleaning pipes 95. By selecting and controlling the above valves, CIP and clean water cleaning can be performed on the first rotary conical distillation column 1, the second rotary conical distillation column 2, the first feed pipe 5, the second feed pipe 52, and the two primary condensers 3. This is common knowledge to those skilled in the art and will not be described further here. Material control valves 56 are also installed between the feed cleaning pipe 95 and the connection between the two feed pipes and the two rotary conical distillation columns, respectively, to control the feeding at the inlets of the first rotary conical distillation column 1 and the second rotary conical distillation column 2.

[0026] This utility model can operate in the following three modes:

[0027] 1. The first rotary cone distillation column 1 and the second rotary cone distillation column 2 are used independently: close the conversion control valve 42 on the first connecting pipe 4 and the second connecting pipe 41, and then control the operation of the feeding device, slag discharge device and cooling discharge device of the first rotary cone distillation column 1 and the second rotary cone distillation column 2 according to production use, so as to realize that the first rotary cone distillation column 1 and the second rotary cone distillation column 2 can be used independently for extraction and processing.

[0028] 2. The first rotary cone distillation column 1 and the second rotary cone distillation column 2 are used in parallel: Open the first feed control valve 51 and material control valve 56 on the first feed pipe 5, open the second feed control valve 53 and material control valve 56 on the second feed pipe 52, open the slag discharge valve 67, slag discharge pump 66 and first slag discharge control valve 61 on the first slag discharge pipe 6, open the slag discharge valve 67, slag discharge pump 66 and second slag discharge control valve 63 on the second slag discharge pipe 62, open the residue discharge control valve 65 on the residue discharge pipe 64, and close the switching control valve 42 on the first connecting pipe 4 and the second connecting pipe 41. The two cooling discharge devices of the first rotary cone distillation column 1 and the second rotary cone distillation column operate normally, and the first rotary cone distillation column 1 and the second rotary cone distillation column 2 are connected in parallel for normal product extraction and processing.

[0029] 3. The first rotary cone distillation column 1 and the second rotary cone distillation column 2 are used in series: Open the first feed control valve 51 and material control valve 56 on the first feed pipe 5, the slag discharge valve 67 and slag discharge pump 66 on the first slag discharge pipe 6, the switching control valve 42 on the first connecting pipe 4, and the material control valve 56 on the second feed pipe 52. Then open the slag discharge valve 67 and slag discharge pump 66 and the second slag discharge control valve 63 on the second slag discharge pipe 62, and the residue discharge control valve 65 on the residue discharge pipe 64. Close the second feed control valve 53 on the second feed pipe 52, the first slag discharge control valve 61 on the first slag discharge pipe 6, and the switching control valve 42 on the second connecting pipe 41. The cooling and discharging devices of the first rotary cone distillation column 1 and the second rotary cone distillation column 2 operate normally. In this way, the residue after distillation and extraction in the first rotary cone distillation column 1 enters the second rotary cone distillation column 2 for further distillation and extraction, and the product is processed in series for secondary extraction.

[0030] Alternatively, one can open the second feed control valve and material control valve 56 on the second feed pipe, the slag discharge valve 67 and slag discharge pump 66 on the second slag discharge pipe 62, the switching control valve 42 on the second connecting pipe 41, and the material control valve 56 on the first feed pipe 5. Then, open the slag discharge valve 67, slag discharge pump 66, and first slag discharge control valve 61 on the first slag discharge pipe 6, and the residue discharge control valve 65 on the residue discharge pipe 64. Close the first feed control valve 51 on the first feed pipe 5, the second slag discharge control valve 63 on the second slag discharge pipe 62, and the switching control valve 42 on the first connecting pipe 4. The cooling and discharging devices of the first rotary cone distillation tower 1 and the second rotary cone distillation tower 2 will operate normally. In this way, the residue after distillation and extraction in the second rotary cone distillation tower 2 will enter the first rotary cone distillation tower 1 for further distillation and extraction, and perform secondary processing of the product through series extraction.

[0031] When the present invention operates in the above-mentioned working mode, the cleaning system is in a closed and stopped state, while the vacuum pump 8 of the steam supply device and the cooling discharge device operates normally according to the working requirements.
