[0024] Embodiment 1

[0025] Please refer to Figure 1 and Figures 3 to 5As shown in the figure, the present utility model provides a lactic acid fermentation beverage production device based on the efficient utilization of broken rice, which includes a crushing box 1, a gelatinization tank 2, an enzymolysis tank 3 and a fermentation tank 4. Inside the fermentation tank 4, an inner cylinder 5 is fixedly arranged. At the top of the inner wall of the inner cylinder 5, a temperature sensor 6 is fixedly connected, which is used to monitor the temperature change of the fermentation beverage in real time. An annular pipe 7 is fixedly connected to the outside of the inner cylinder 5, and a plurality of nozzles 8 are arranged at the bottom of the annular pipe 7. On one side of the fermentation tank 4, a water tank 9 is arranged, and at the bottom of the inner wall of the water tank 9, a semiconductor refrigeration sheet 10 is arranged. The semiconductor refrigeration sheet 10, also called a thermoelectric refrigeration sheet, is a heat pump, which is an existing technology. Heat can be absorbed and released at both ends of the thermocouple respectively, so as to achieve the purpose of refrigerating the water in the water tank 9, which is convenient for the cooling water to maintain its low temperature during continuous circulation, improving the cooling effect and efficiency. A stirring assembly is arranged inside the inner cylinder 5;

[0026] The stirring assembly includes a stirring rod 11. A cavity 12 is opened inside the stirring rod 11. At the top of the inner wall of the cavity 12, an electric push rod 13 is fixedly connected. The electric push rod 13 drives several sleeves 14 to move up and down by driving a connecting plate 15 and a connecting rod 16. Thus, while the stirring rod 11 rotates, the stirring blades 17 are driven to move up and down, so as to fully mix the fermentation liquid and improve the efficiency of temperature adjustment. A plurality of sleeves 14 are sleeved on the surface of the stirring rod 11. Between the two sides of the inner wall of the sleeve 14, a connecting plate 15 is fixedly connected. Between every two connecting plates 15, a connecting rod 16 is fixedly connected. Stirring blades 17 are fixedly connected to both sides of the sleeve 14. The top of the uppermost connecting plate 15 is fixedly connected to the output end of the electric push rod 13. A heating plate 18 is arranged inside the stirring blade 17;

[0027] On both sides of the stirring rod 11, movable grooves 19 adapted to the connecting plate 15 are opened. A heating wire 20 is arranged inside the inner cylinder 5. The top end of the stirring rod 11 penetrates through the inner cylinder 5 and extends to the outside of the fermentation tank 4. At the top of the fermentation tank 4, a servo motor 21 connected to the top of the stirring rod 11 is fixedly connected through a bracket;

[0028] At the top of the water tank 9, a water pump 22 is fixedly connected. The water inlet of the water pump 22 is communicated with a water suction pipe 23, and the water outlet of the water pump 22 is communicated with a water outlet pipe 24 connected to the annular pipe 7;

[0029] The bottom of the crushing box 1 is connected to the top of the gelatinization tank 2. Inside the gelatinization tank 2, there are heating devices, heat preservation devices and stirring devices, which are used for heating and gelatinizing the rice slurry (a mixture of rice flour and water in proportion). The liquid outlet of the gelatinization tank 2 is connected to the feed inlet of the enzymolysis tank 3 through a delivery pump 29 and a delivery pipeline. Inside the enzymolysis tank 3, there are cooling devices, heating devices, heat preservation devices and stirring devices, and a steam pipe is also arranged at the top, which is used to turn on the jacket direct steam for enzyme inactivation operation to ensure the complete termination of the enzymolysis process. The enzymolysis tank 3 is connected to the top of the inner cylinder 5 through a delivery pump 29 and a delivery pipeline. On one side of the fermentation tank 4, there is a control device 30, which is used for inputting fermentation parameters, monitoring the fermentation process and controlling operations such as the start and stop of the device.

[0030] Through the setting of the above structure, the temperature sensor 6 monitors the temperature change in real time. When the temperature is too high, by spraying circulating cooling water onto the outside of the inner cylinder 5, the temperature during fermentation can be reduced. When the temperature is too low, through the heating wire 20 and the heating plate 18, and in cooperation with the setting of the stirring assembly, the liquid can be heated evenly and quickly, and the efficiency of temperature adjustment is higher, which improves the efficiency of fermentation.

[0031] Embodiment 2

[0032] On the basis of Embodiment 1, please refer to Figure 1 and Figure 2 As shown, two crushing rollers 25 are arranged inside the crushing box 1. A sieve mesh 26 is arranged between the two sides of the inner wall of the crushing box 1. The inner wall of the crushing box 1 is fixedly connected with a vibration motor 27 through a support plate, and the output end of the vibration motor 27 is connected to the bottom of the sieve mesh 26. An outlet 28 is arranged on one side of the crushing box 1 and at the top of the sieve mesh 26. Workers can collect the over-sized particles after screening at the outlet 28, which is convenient for re-crushing.

[0033] Through the setting of the above structure, the crushing rollers 25 crush the broken rice into smaller particles. The crushed broken rice particles are screened through the sieve mesh 26 to remove the over-sized particles. The screened broken rice is then prepared to enter the next fermentation process. Pretreating the broken rice before fermentation is beneficial to improving the subsequent fermentation effect.

[0034] At the same time, the content not described in detail in this specification belongs to the well-known prior art in the art, and the model parameters of each electrical appliance are not specifically limited. Conventional equipment suitable for the device can be used.

[0035] In use, broken rice is put into the crushing box 1, and the broken rice is crushed by the crushing roller 25. The crushed broken rice particles are screened through the screen 26 to remove oversized particles. The oversized particles can be discharged from the crushing box 1 through the discharge port 28 for re-crushing. At the same time, the vibration motor 27 speeds up the screening efficiency of the screen 26. The screened broken rice is discharged downward and enters the gelatinization tank 2. The rice flour and water are mixed in proportion, and the heating device and stirring device inside the gelatinization tank 2 are used to heat and gelatinize the rice slurry. Then, the conveying pump transports the gelatinized rice paste to the enzymatic hydrolysis tank 3 for enzymatic hydrolysis of the gelatinized rice paste. After the enzymatic hydrolysis is completed, direct steam is passed into the jacket through the steam pipe for enzyme inactivation operation to ensure the complete termination of the enzymatic hydrolysis process. Subsequently, through cooling and opening the discharge valve, the fermented bottom material of the rice milk after enzymatic hydrolysis is transported to the inner cylinder 5 of the fermentation tank 4. The servo motor 21 is started to drive the stirring rod 11 to rotate. The stirring rod 11 drives a plurality of stirring blades 17 to rotate. At the same time, the electric push rod 13 is started. While the stirring rod 11 is rotating, through the sleeve 14 and the connecting rod 16, it can drive a plurality of stirring blades 17 to move up and down simultaneously to uniformly stir the fermented liquid. The heating wire 20 and the heating plate 18 in the stirring blade 17 heat the fermented liquid. The temperature sensor 6 detects the fermentation temperature. When the temperature is too high, the water pump 22 is started, and cooling water is sprayed onto the outside of the inner cylinder 5 through the water suction pipe 23, the water outlet pipe 24, the annular pipe 7 and a plurality of nozzles 8, which can reduce the temperature during fermentation. The heated water after spraying flows back into the water tank 9 again, and the semiconductor refrigeration sheet 10 cools the water for convenient recycling and improves the cooling efficiency. On the contrary, when the temperature is too low, through a plurality of heating wires 20 and the heating plate 18 arranged in the stirring blade 17, the liquid can be uniformly and quickly heated, and the temperature adjustment efficiency is higher.

[0036] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
