Description

Technical Field

[0001] This utility model relates to the field of liquor brewing, and in particular to a liquor brewing ripening device. Background Technology

[0002] The aging process in baijiu brewing accelerates the aging of the liquor through artificial intervention. It is a commonly used method to improve the efficiency of baijiu brewing and has significant advantages such as shortening the aging cycle, improving taste and flavor, enhancing quality and economic benefits, and improving environmental protection and safety. However, existing baijiu brewing technologies usually use a single method sequentially. For example, baijiu is first introduced into an ultrasonic treatment chamber for ultrasonic aging, then into a microwave treatment chamber for microwave aging, and finally into an oxidation treatment chamber for oxidative aging. This method cannot integrate the two methods together for efficient aging of the baijiu, resulting in the inability to further improve the efficiency of baijiu brewing. Utility Model Content

[0003] In order to overcome the shortcomings of existing baijiu brewing technology, which only uses a single method to sequentially accelerate the ripening process, resulting in the inability to further improve the brewing efficiency, this utility model provides a baijiu brewing ripening device.

[0004] Technical solution: A baijiu (Chinese liquor) brewing and ripening device, comprising a fixed frame, a ripening chamber, a liquid inlet valve, a liquid outlet valve, an air inlet valve, an air supply pipe, an air jet pipe, a drive mechanism, microwave transmitters, and microwave reflectors; the ripening chamber is fixedly connected to the fixed frame; the liquid inlet valve and the liquid outlet valve are sequentially installed on the ripening chamber; the air inlet valve is installed on the ripening chamber; the air supply pipe is rotatably connected inside the ripening chamber; the air supply pipe is connected to the air inlet valve; at least two air jet pipes are connected to the air supply pipe; a drive mechanism for driving the air supply pipe to rotate is connected to the ripening chamber; the drive mechanism is connected to the air supply pipe; several microwave transmitters are installed on the ripening chamber; each air jet pipe has a microwave reflector fixedly connected to it, and the microwave reflector is in an inclined state.

[0005] Furthermore, it is particularly preferred that the drive mechanism consists of a driven spur gear, a motor, and a driving spur gear; the driven spur gear is fixedly connected to the gas supply pipe; the motor is installed on the ripening chamber; the output shaft of the motor is fixedly connected to the driving spur gear; and the driving spur gear meshes with the driven spur gear.

[0006] Furthermore, it is particularly preferred that each microwave reflector has a built-in plate for strengthening the structure.

[0007] Furthermore, it is particularly preferred that the outlet end of the jet pipe is aligned with the adjacent microwave reflector, so that when oxygen is ejected outward from the outlet end of the jet pipe, the rotating microwave reflector can promptly stir and diffuse the oxygen in all directions.

[0008] In addition, it is particularly preferred that the ripening chamber is equipped with an oxygen concentration detector for monitoring the oxygen concentration in the liquor.

[0009] In addition, it is particularly preferred that the ripening chamber is equipped with a temperature monitor for monitoring the temperature inside the liquor.

[0010] In addition, it is particularly preferred that a cold water pipe is fixedly connected inside the ripening chamber.

[0011] Furthermore, it is particularly preferred that the cold water pipe is composed of multiple S-shaped pipes joined together.

[0012] Beneficial Effects: This utility model provides a baijiu (Chinese liquor) brewing and ripening device. It not only includes a gas supply pipe that, in conjunction with a jet pipe, periodically delivers oxygen to the baijiu in the ripening chamber, but also a microwave transmitter that, in conjunction with a microwave reflector, periodically emits ripening microwaves into the baijiu. This allows for alternating microwave and oxygen ripening treatments of the baijiu. During this process, the microwave reflector acts as a stirring component to uniformly stir and diffuse the oxygen in the baijiu. Furthermore, as the microwave reflector rotates, it sequentially reflects and diffuses the emitted microwaves to various areas of the baijiu, preventing localized high temperatures caused by concentrated microwaves. This ensures safe ripening of the baijiu while improving the efficiency of combined ripening processes. It also solves the technical problem of existing baijiu brewing technologies that rely solely on single-method sequential ripening, hindering further improvements in brewing efficiency.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example

[0020] This embodiment provides a device for accelerating the fermentation of baijiu (Chinese white liquor), such as... Figures 1-4 As shown, the device includes a fixed frame 1, a ripening chamber 2, an inlet valve 21, an outlet valve 22, an air inlet valve 31, an air supply pipe 32, an air jet pipe 33, a drive mechanism, a microwave transmitter 41, and a microwave reflector 42. The ripening chamber 2 is fixedly connected to the fixed frame 1. The ripening chamber 2 is sequentially equipped with an inlet valve 21 for inputting liquor and an outlet valve 22 for discharging liquor, both initially closed. An air inlet valve 31 is installed on the ripening chamber 2, also initially closed, and is connected to an external oxygen supply device. An air supply pipe 32 is rotatably connected inside the ripening chamber 2. 32 connects to the air inlet valve 31; two jet pipes 33 are connected to the air supply pipe 32; a drive mechanism is connected to the ripening chamber 2; the drive mechanism is connected to the air supply pipe 32; several microwave transmitters 41 are installed on the ripening chamber 2; a microwave reflector 42 is fixedly attached to each jet pipe 33, and the microwave reflector 42 is in an inclined state; each microwave reflector 42 has a built-in plate, which can strengthen the structural strength of the microwave reflector 42 against the impact of fluid, allowing the microwave reflector 42 to rotate and stir as a stirring blade in the liquor; each outlet end of the jet pipe 33 is aligned with the adjacent microwave reflector 42.

[0021] like Figure 3 As shown, the drive mechanism in this embodiment consists of a driven spur gear 34, a motor 35, and a drive spur gear 36; the driven spur gear 34 is fixedly connected to the gas supply pipe 32; the motor 35 is installed on the ripening chamber 2; the output shaft of the motor 35 is fixedly connected to the drive spur gear 36; the drive spur gear 36 meshes with the driven spur gear 34.

[0022] like Figure 2 As shown, in this embodiment, an oxygen concentration detector 51 is installed in the ripening chamber 2; a temperature monitor 52 is installed in the ripening chamber 2; a cold water pipe 6 is fixedly connected in the ripening chamber 2, and both the inlet and outlet ends of the cold water pipe 6 are externally connected to a coolant circulation conveying device; the cold water pipe 6 is composed of multiple S-shaped pipes spliced ​​together, which increases the contact surface area between the cold water pipe 6 and the liquor in the ripening chamber 2.

[0023] The working steps of a liquor brewing and ripening device in this embodiment are as follows.

[0024] First, open the liquid inlet valve 21 to pour the liquor into the aging chamber 2. After closing the liquid inlet valve 21, turn on the motor 35 to drive the drive spur gear 36 to rotate. The drive spur gear 36 meshes with the driven spur gear 34 to drive the gas supply pipe 32 to rotate. The gas supply pipe 32 continuously drives the jet pipe 33 and the microwave reflector plate 42 to rotate slowly. The microwave reflector plate 42 stirs the liquor. Then, the liquor in the aging chamber 2 is alternately treated with microwave aging and oxygen aging at regular intervals.

[0025] During the timed oxygen aging process of baijiu, the air inlet valve 31 is in the open state. The external oxygen delivery equipment continuously delivers oxygen to the two jet pipes 33 through the air inlet valve 31 and the air delivery pipe 32. The two jet pipes 33 spray oxygen into the baijiu in the aging chamber 2. At the same time, the rotating microwave reflector 42 stirs the oxygen in the baijiu in time, so that the oxygen can be evenly diffused to all areas of the baijiu. During this process, the oxygen concentration detector 51 continuously monitors the oxygen concentration in the baijiu. When the oxygen concentration detector 51 detects that the oxygen concentration in the baijiu is higher than 1.2 mg / L, the external oxygen delivery equipment stops delivering oxygen, and the air inlet valve 31 switches to the closed state. At this time, the oxygen in the baijiu will be gradually consumed during the aging process, completing the oxygen aging process of this stage.

[0026] In the timed microwave aging process of baijiu, it is necessary to simultaneously meet two conditions: the oxygen concentration detector 51 detects that the oxygen concentration in the baijiu is below 0.8 mg / L, and the temperature monitor 52 detects that the temperature in the baijiu is below 45°C. This is to avoid the risk of explosion caused by microwave radiation when the baijiu is in excessively high temperature or oxygen concentration conditions. At this time, the microwave transmitter 41 intermittently emits microwaves into the baijiu in the aging chamber 2, while the microwave reflector 42 remains in a rotating state. The rotating microwave reflector 42 will change its tilt angle relative to the microwave transmitter 41. Therefore, the microwaves intermittently emitted from the microwave transmitter 41 will be reflected in different directions in the baijiu along the tilted microwave reflector 42. This not only allows the microwaves to be evenly radiated to all areas of the baijiu, but also avoids the high temperature phenomenon caused by the concentration of microwaves in local areas of the baijiu. When the temperature monitor 52 detects that the temperature in the baijiu exceeds 45°C, the microwave transmitter 41 stops emitting microwaves, and the microwave aging process for this stage is completed.

[0027] During the microwave aging process of baijiu, when the temperature monitor 52 detects that the temperature inside the baijiu exceeds 48°C, the baijiu is in an abnormally high temperature state. At this time, an external coolant circulation and delivery device is needed to circulate coolant to the cold water pipe 6. The coolant flowing continuously through the cold water pipe 6 will cool the baijiu in the aging chamber 2 in time, so that the baijiu can be cooled to below 45°C as soon as possible.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that variations may be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
