[0027] Example 1 The malt mashing process using the aforementioned integrated malt whisky mashing and fermentation vessel includes the following steps: In the first step, the circulation port valve 15-1, the saccharification pot interface valve 16-1, the fluid pump interface valve 9-4, the second fluid pump interface valve 18-1, and the fermentation tank bottom valve 6 are all closed.

[0028] The second step involves feeding the first batch of 60-70°C hot water into the saccharification pot 13 through the feeding port 1, and adding crushed malt obtained from crushing into the saccharification pot 13 through the feeding port 1. The motor 17 drives the stirring rake 12 to rotate, stirring the water and crushed malt in the saccharification pot 13 evenly. After 2-5 minutes, the stirring is stopped. After 1-2 hours, the crushed malt in the saccharification pot 13 is fully saccharified to obtain wort. The wort is filtered through the filter plate 3 to obtain the first wort. Subsequently, the saccharification pot interface valve 16-1, the fluid pump interface valve 9-4, and the fermentation tank bottom valve 6 are opened, and the first bidirectional fluid pump 7 is started. The first wort flows into the first pipe 9-1 from the outlet 16, is cooled down by the heat exchanger 10, and then flows through the second pipe 9-2 and the first bidirectional fluid pump 7 in sequence under the action of gravity and the first bidirectional fluid pump 7 before entering the fermentation tank 5. After maintaining this for 0.5 to 1 hour, the third step is carried out.

[0029] The third step is to add a second batch of water into the saccharification pot 13 through the feeding port 1. The second batch of water is used to wash the saccharification pot 13 to obtain wort. The wort is then filtered through the filter plate 3 to obtain the second batch of wort. The second wort flows into the first pipe 9-1 from the outlet 16, is cooled by the heat exchanger 10, and then flows through the second pipe 9-2 and the first bidirectional fluid pump 7 under the action of gravity and the first bidirectional fluid pump 7 into the fermentation tank 5. After being maintained for 0.5 to 1 hour, the fourth step is carried out.

[0030] Fourth step: Close the bottom valve 6 of the fermenter, shut down the first bidirectional fluid pump 7, open the interface valve 18-1 of the second fluid pump and start the second bidirectional fluid pump 18; A third batch of water is added to the saccharification pot 13 through the feeding port 1. The third batch of water is used to wash the saccharification pot 13 to obtain a low concentration of wort. The low concentration of wort is filtered through the filter plate 3 to obtain the third batch of wort. The third wort flows into the first pipe 9-1 from the outlet 16, is cooled down by the heat exchanger 10, and then flows through the third pipe 9-3 and the second bidirectional fluid pump 18 in sequence under the action of gravity and the second bidirectional fluid pump 18 into the weak wort tank. After maintaining for 0.5~1h, the second fluid pump interface valve 18-1 is closed and the second bidirectional fluid pump 18 is turned off, and then the fifth step is carried out. Fifth step, open the slag discharge port 11, discharge the slag in the saccharification pot 13 through the slag discharge port 11, and then close the slag discharge port 11; When a stirring rake 12 and a motor 17 are provided, the stirring rake 12 can be driven to rotate by the motor 17 to assist in the slag removal process.

[0031] Step 6: Sterile water and yeast are added to the saccharification pot 13 through the feeding port 1 to activate the yeast in the saccharification pot 13 and obtain a yeast solution. Subsequently, the first bidirectional fluid pump 7 is started; the yeast solution flows into the first pipe 9-1 from the outlet 16, and under the action of gravity and the first bidirectional fluid pump 7, it flows through the second pipe 9-2 and the first bidirectional fluid pump 7 in sequence into the fermentation tank 5, where it mixes with the first wort and the second wort in the fermentation tank 5. Then, water is added to the saccharification pot 13 through the feeding port 1 to wash the yeast solution. The washing water mixed with the yeast solution flows into the first pipe 9-1 through the discharge port 16. Under the action of gravity and the first bidirectional fluid pump 7, it flows through the second pipe 9-2 and the first bidirectional fluid pump 7 in sequence and enters the fermentation tank 5 to obtain the mixed liquid in the fermentation tank 5. Step 7: Ferment the mixture in fermentation tank 5. Fermentation gas is discharged through fermentation exhaust pipe 2 to obtain fermentation liquid. After fermentation is complete, close the fluid pump interface valve 9-4, open the second fluid pump interface valve 18-1, and start the first bidirectional fluid pump 7 and the second bidirectional fluid pump 18. The fermentation broth is then sent to the distiller sequentially through the second pipe 9-2, the first bidirectional fluid pump 7, the third pipe 9-3, and the second bidirectional fluid pump 18.

Close the mashing pot interface valve 16-1 and turn off the second bidirectional fluid pump 18. Subsequently, crushed malt is fed into the saccharification pot 13 through the feeding port 1.

[0034] Step 7: Motor 17 drives stirring rake 12 to rotate, stirring the weak wort and broken malt in saccharification pot 13 evenly, and let it stand for 1-2 hours to obtain wort. The wort is filtered through filter plate 3 to obtain the fourth wort. Subsequently, the saccharification tank interface valve 16-1 is opened, and the second bidirectional fluid pump 18 is started. The fourth wort flows into the first pipe 9-1 from the outlet 16, is cooled down by the heat exchanger 10, and then flows through the third pipe 9-3 and the second bidirectional fluid pump 18 in sequence under the action of gravity and the second bidirectional fluid pump 18 before entering the weak wort tank. After maintaining this for 0.5 to 1 hour, the second bidirectional fluid pump 18 is turned off.

[0035] Step 8: Add hot water at 70-80℃ into the saccharification pot 13 through the feeding port 1, let it stand for 10-20 minutes to obtain wort, and filter the wort through the filter plate 3 to obtain the fifth wort. Subsequently, the second bidirectional fluid pump 18 is started, and the fifth wort flows into the first pipe 9-1 from the outlet 16. It is cooled down by the heat exchanger 10 and then flows through the third pipe 9-3 and the second bidirectional fluid pump 18 in sequence under the action of gravity and the second bidirectional fluid pump 18 into the weak wort tank. After maintaining for 0.5~1h, the saccharification pot interface valve 16-1 is closed and the second bidirectional fluid pump 18 is turned off. Then, drain the trough according to the method in step 5 of Example 1.

[0036] Step 9: Open the saccharification tank interface valve 16-1, start the second bidirectional fluid pump 18, and the mixture of the fourth and fifth wort in the weak wort tank flows through the third pipe 9-3 and the first pipe 9-1 in sequence and enters the saccharification tank 13 through the discharge port 16. Then close the second fluid pump interface valve 18-1 and the second bidirectional fluid pump 18. Subsequently, yeast is added into the saccharification pot 13 through the feeding port 1, the fermentation tank bottom valve 6 and the circulation port valve 15-1 are opened, and the first bidirectional fluid pump 7 is started. The mixture of the fourth and fifth wort in the saccharification pot 13 and the yeast flow into the first pipe 9-1 through the discharge port 16, and under the action of gravity and the first bidirectional fluid pump 7, it flows through the second pipe 9-2 and the first bidirectional fluid pump 7 in sequence into the fermentation tank 5, where it mixes with the mixture of the first and second wort in the fermentation tank to form mixed wort. Subsequently, the mixed wort is circulated and mixed evenly in the fermentation tank 5, fermentation exhaust rod 2, circulation hole 15, saccharification pot 13, discharge port 16, first pipe 9-1, and second pipe 9-2 under the action of the first bidirectional fluid pump 7, and maintained for 10~20 minutes, and then the first bidirectional fluid pump 7 is turned off.

[0037] Step 10: After mixing the wort and letting it stand for 3-7 days, the fermentation liquid is obtained. Then, the second fluid pump interface valve 18-1 is opened, and the first bidirectional fluid pump 7 and the second bidirectional fluid pump 18 are started. The fermentation liquid is distilled sequentially through the second pipe 9-2, the first bidirectional fluid pump 7, the third pipe 9-3 and the second bidirectional fluid pump 18, or sequentially through the first pipe 9-1, the third pipe 9-3 and the second bidirectional fluid pump 18.
