[0029] In the production of fermented beverages such as beer and wine, the addition of yeast is one of the key steps; traditional methods of yeast addition are mostly manual and intermittent, which have the following drawbacks:

[0030] Low addition accuracy: Manual addition makes it difficult to accurately control the amount added, which can easily lead to yeast waste or poor fermentation results.

[0031] High labor intensity: Manual addition requires frequent operation, which is labor-intensive and inefficient.

[0032] Low level of automation: It is difficult to achieve automated control, which is not conducive to the stable operation of the fermentation process.

[0033] Therefore, the design concept of this application is to design a device that can automatically add yeast, replacing manual intermittent addition. It can add yeast quantitatively with high precision, low labor intensity, and can achieve automated operation, which is beneficial to the stability of the fermentation process.

The peristaltic pump 8 is connected to a fermentation tank 9.

[0035] The feed pipe 4 is equipped with a feed valve 10; the feed valve 10 is connected to a conveying pump, the conveying pump is connected to a storage tank, the storage tank contains yeast suspension, the conveying pump is also connected to the controller 2, when the yeast storage tank 1 needs to be replenished, the controller 2 controls the conveying pump to start and the feed valve 10 to open, so as to pump the yeast suspension in the storage tank into the yeast storage tank 1.

[0036] The stirring device 5 is an electric paddle type. When adding yeast suspension, stirring is required to avoid sedimentation and uneven feeding. In actual use, a ready-made stirring device 5 can be purchased directly. Of course, users can also purchase other types of stirring devices 5.

[0037] The outlet of the discharge tee 7 is connected to a discharge valve 11, which is connected to a peristaltic pump 8. When in use, the discharge valve 11 is opened, and the peristaltic pump 8 draws out the yeast suspension in the yeast storage tank 1 and pumps it to the fermentation tank 9. The peristaltic pump 8, also known as a quantitative peristaltic pump, is a type of pump that uses peristalsis to transport liquids. Its working principle is to generate a peristaltic effect by compressing the deformation of a hose or an elastic peristaltic body, thereby realizing the quantitative transport of fluids. In this application, the peristaltic pump 8 is used to quantitatively add yeast suspension to the fermentation tank 9.

[0038] The other end of the discharge tee pipe 7 is connected to an air vent valve 12. When in use, opening the air vent valve 12 will completely drain the yeast suspension in the yeast storage tank 1, so that cleaning, maintenance and other operations can be carried out.

It is also responsible for sending operation commands to the stirring control module according to preset settings (timed). It is responsible for sending operation commands to the discharge control module according to preset settings (quantitative). It is also responsible for sending operation commands to the venting control module according to manual operation. The feed control module is responsible for controlling the opening and closing of the feed valve 10 and the start and stop of the delivery pump according to the information sent by the information processing module. The stirring control module is responsible for controlling the start and stop of the stirring device 5 according to the information sent by the information processing module.

The controller 2 controls the feed valve 10 and the delivery pump to replenish the yeast storage tank 1. When adding yeast, the controller 2 controls the stirring device 5 to run according to the preset time to stir the yeast suspension, making the yeast suspension more uniform. After stirring is completed, the controller 2 controls the start and stop of the peristaltic pump 8 and the flow rate according to the preset dosage to quantitatively deliver the yeast suspension to the fermentation tank 9, realizing continuous automatic addition of yeast suspension. When the yeast storage tank 1 needs to be cleaned or repaired, the controller 2 controls the drain valve 12 to open, and the yeast suspension in the yeast storage tank 1 flows out and is emptied.

[0042] The can lid 3 is provided with an exhaust pipe 13, and the outer wall of the exhaust pipe 13 is provided with an exhaust hole 14. In this application, the exhaust hole 14 is only provided on the outer wall of the exhaust pipe 13, and the top wall of the exhaust pipe 13 is not provided. This design can better prevent impurities from entering the yeast storage tank 1 and contaminating the yeast suspension.

[0043] Yeast storage tank 1: Used to store yeast suspension, with a stirring device 5, a feed pipe 4 and an exhaust pipe 13 at the top, and a discharge tee pipe 7 (for discharging and venting) at the bottom.

[0044] Peristaltic pump 8: Connected to the outlet of the discharge tee 7 of yeast storage tank 1, used to quantitatively deliver yeast suspension to fermentation tank 9; the connecting pipe of peristaltic pump 8 is made of silicone or PharMed BPT hose.

[0045] Liquid level sensor 6: installed inside yeast storage tank 1 to monitor the liquid level inside yeast storage tank 1; a capacitive liquid level sensor or an ultrasonic liquid level sensor can be used.

[0046] Stirring device 5: It adopts an electric paddle type, with the end of the stirring paddle extending into the yeast storage tank 1 to stir the yeast suspension and avoid problems such as sedimentation of the yeast suspension.
