Description

Technical Field

[0001] This utility model relates to a cooling machine and is situated in the field of brewing equipment technology. Background Technology

[0002] In the process of baijiu brewing, the mash after steaming needs to be fermented with koji powder. Koji powder plays a crucial role in the fermentation of the mash, promoting saccharification and fermentation, thus affecting the taste and flavor of the baijiu. Current technology cannot effectively control the amount of koji powder added, resulting in uneven mixing of the added koji powder with the cooled mash, severely affecting the fermentation effect and consequently impacting the quality of the baijiu during subsequent distillation.

[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] like Figure 1-4 As shown, a cooling machine includes a chain conveyor 1. The chain conveyor 1 has an internal blowing device 2. Baffles 3 are located on both sides of the chain conveyor 1. A steam suction hood 4 is fixedly connected to the middle of the baffles 3. The steam suction hood 4 is arc-shaped, and its top is connected to a steam suction pipe, which is connected to an exhaust fan (not shown in the figure). A support frame 5 is fixedly connected to the end of the chain conveyor 1. Weighing sensors 6 are located at the four corners of the top of the support frame 5. A koji powder feeding device 7 for evenly distributing koji powder is installed on the weighing sensors 6. A hopper support 8 is placed at the top of the koji powder feeding device 7. A koji powder hopper 9 is fixedly connected inside the hopper support 8, and the bottom opening of the koji powder hopper 9 corresponds to the inlet of the koji powder feeding device 8. A baffle 12 is fixedly connected to the end of the chain conveyor 1 to prevent the output mash from spilling outside the designated area. The weighing sensor 6 is electrically connected to the PLC controller, which is connected to the control panel. The control panel can display the weighing weight corresponding to the weighing sensor 6 and monitor the amount of koji powder in the koji powder hopper 9 in real time to avoid the situation where the mash is continuously conveyed without the addition of koji powder.

[0020] The blowing device 2 includes a bellows 201 with a top opening corresponding to the chain plate, and a fan 202 is provided on the side of the bellows 201. Multiple fans 202 are provided, each fan 202 connected to two connected bellows 201. When the fan 202 is activated, the generated air blows along the opening at the top of the bellows 201 towards the chain plate. There are gaps between the chain plates, allowing airflow to escape through these gaps, thereby cooling the mash conveyed on the chain plate. The water vapor generated during the cooling process is recovered and treated by the suction pipe connected to the suction hood 4, preventing a large amount of water vapor from spreading into the workshop and affecting the working environment.

[0021] The chain conveyor 1 is equipped with multiple temperature sensors connected to a PLC controller to detect the temperature of the mash conveyed on the chain. When the temperature of the mash upstream of the support frame 5 is detected to be higher than the set value, it indicates that relying solely on the fan 202 for air cooling is not effective enough, and water needs to be added to assist in cooling. The temperature sensors are infrared temperature sensors, and the control panel can display the temperature values ​​detected by each temperature sensor in real time.

[0022] To improve the cooling effect, at least two turning rollers 10 are rotatably connected between the baffles 3, and multiple U-shaped rods 11 are staggered on the turning rollers 10. The U-shaped rods 11 continuously turn the mash conveyed on the chain plate, which can improve the cooling effect and spread the mash conveyed on the chain plate as evenly as possible, so that the added yeast powder can be mixed evenly.

[0023] To further improve the mixing effect of koji powder and mash, a turning roller 10 is installed at the bottom of the support frame 5 near the outlet of the chain conveyor 1. After the koji powder is sprinkled onto the mash, it is directly turned over by the turning roller 10.

[0024] The koji powder feeding device 7 includes a square frame 701. A hopper 702, corresponding to the bottom opening of the koji powder hopper 9, is fixedly connected inside the square frame 701. A spiral stirring roller 703 is rotatably connected to the constricted position of the hopper 702. A koji powder discharge cylinder 705 is fixedly connected to the outlet end of the hopper 702. The top opening of the discharge cylinder 705 communicates with the outlet of the hopper 702. The bottom of the discharge cylinder 705 is provided with a guide port for discharging koji powder. Guide rollers 706 are rotatably connected to both sides of the discharge cylinder 705. The guide rollers 706 have a toothed cross-section and are set close to the inner wall of the discharge cylinder 705. A gear 707, which is linked by a chain, is provided at one end of the spiral stirring roller 703 that passes through the hopper 702 and at one end of the guide roller 706 that passes through the discharge cylinder 705. The spiral stirring roller 703 and the guide roller 706 rotate simultaneously via chain drive. The spiral stirring roller 703 disperses the koji powder falling from the koji powder hopper 9 into the koji powder discharge cylinder 705, causing it to fall onto the guide roller 706. Because the guide roller 706 is set close to the inner wall of the koji powder discharge cylinder 705, the koji powder cannot fall automatically when the guide roller 706 is static. When the spiral stirring roller 703 and the guide roller 706 rotate simultaneously, the falling koji powder can fall into the gaps on the surface of the guide roller 706. As the guide roller 706 rotates, the koji powder slowly falls from the guide port onto the mash on the chain conveyor device 1. The design of the guide roller 706 allows the koji powder to be evenly sprinkled on the mash, resulting in more uniform mixing and improved subsequent fermentation effects.

[0025] The spiral stirring roller 703 is provided with spiral blades 704. There are two spiral blades 704, which are connected to the spiral stirring roller 703 in opposite spirals. The reverse arrangement of the spiral blades 704 makes the powder hopper more efficient.

[0026] This invention features a simple structure. A chain conveyor 1 transports the cooked mash. A blower 202 is activated, directing airflow from the blower box 201 and through the gaps in the chain, thus cooling the mash. A temperature sensor monitors the temperature of the mash at different conveying sections in real time. If the temperature requirement is not met before the addition of yeast powder, water is added for auxiliary cooling. When the mash reaches the support frame 5, the motor driving the spiral stirring roller 703 is activated. The spiral stirring roller 703 rotates, which in turn drives the guide roller 706 via a chain. The yeast powder is sprinkled onto the mash through the gaps on the surface of the guide roller 706, achieving uniform addition. Combined with the turning roller 10 at the bottom of the support frame 5, and the U-shaped rod 11, the mash with added yeast powder is turned, improving the subsequent fermentation effect. The number of material hoppers on the support frame 5 can be multiple, depending on the actual material discharge requirements. Similarly, multiple openings are set at the bottom of the powder hopper 9. In this embodiment, two are preferred.

[0027] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
