Detailed Implementation
[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.
[0016] Example. A double-coil distillation apparatus, configured as follows: Figure 1 As shown, the system includes a primary distillation unit on the left, a secondary distillation unit on the right, a condenser unit in the middle, an alcohol safety tank 6 in the center, and a collector 7 below the alcohol safety tank 6. Both the primary and secondary distillation units are connected to their respective condenser units and to the inlet of the alcohol safety tank 6. The outlet of the alcohol safety tank 6 is connected to the collector 7. The primary distillation unit includes a primary distillation vessel 1, a conical swan neck 11, a first Lynn arm 12, and a column unit. The secondary distillation unit includes a secondary distillation vessel 2, a lantern-shaped swan neck 21, and a second Lynn arm 22. The condenser unit includes a primary condenser unit and a secondary condenser unit.
[0017] The top of the primary distillation vessel 1 is connected to the first Lynn arm 12 via a conical swan neck 11; the first Lynn arm 12 is inclined to the right and downward, with its middle part connected to the column unit via a branch pipe 13 and its end connected to the primary condenser unit; the column unit consists of a condenser 32 and a column 31 from top to bottom, and the bottom of the column 31 is connected to the primary distillation vessel 1 via a reflux pipe; the first Lynn arm 12 is connected to the condenser 32 and the column 31 via two corresponding branch pipes 13 respectively.
[0018] The top of the distillation vessel 2 is connected to the second Lynn arm 22 via a lantern-shaped swan neck 21; the second Lynn arm 22 is tilted to the left and downward, and its end is connected to the fine condensation unit.
[0019] The primary condensation unit includes a primary first-stage condenser 41 and a primary second-stage condenser 51 connected accordingly; the fine condensation unit includes a fine first-stage condenser 42 and a fine second-stage condenser 52 connected accordingly.
[0020] The collector 7 includes a low-alcohol collection tank 71, a head and tail collection tank 72, a core collection tank 73, and multiple corresponding dispensing valves.
[0021] Both the primary distillation pot 1 and the secondary distillation pot 2 are equipped with heat exchange plates; the heat exchange plates are connected to hot steam.
[0022] The manholes, flanges for various connections, and alcohol safety box 6 of the primary distillation pot 1 and the secondary distillation pot 2 of this application are all made of brass.
[0023] The copper heads of the primary distillation pot 1 and the secondary distillation pot 2 are tapped to increase their surface area, thus increasing the contact area with the alcohol vapor and improving the quality of the liquor.
[0024] Working principle:
[0025] Single malt whisky:
[0026] Primary distillation: The fermentation liquid is placed in the primary distillation pot 1 and heated using a heat exchange plate steam heating method (which has higher heat transfer efficiency). The alcohol vapor is heated to the top of the pot (the copper head is tapped to increase the surface area, thus increasing the contact area with the alcohol vapor), and enters the conical swan neck 11, allowing the alcohol vapor to fully contact and react with the copper wall volume. The alcohol vapor passes through the first Lynn arm 12, and then through the condenser unit to condense the alcohol vapor to below 20°C into the low-alcohol collection tank 71.
[0027] Distillation: The alcohol in the low-alcohol collection tank 71 is pumped into the distillation pot 2, and the initial distillation steps are repeated by heating until the alcohol is transferred to the collection tank corresponding to the collector 7.
[0028] Grain Whiskey:
[0029] Distillation: The fermentation liquid is placed in the primary distillation pot 1 and heated by heat exchange plate steam heating. The alcohol vapor is heated to the top of the pot and then enters the column 31 through the branch pipe 13 via the valve. After passing through the condenser 32, the alcohol vapor is condensed to below 20°C by the condensation unit and then sent to the head and tail collection tank 72 and the heart collection tank 73 respectively.
