Description

Technical Field

[0001] The invention relates to the technical field of fermentation devices, in particular to a rice noodle fermentation device. Background Art

[0002] Rice noodles are one of the traditional staple foods in China. They are easy to make, light in taste, and rich in nutrition, making them popular among people. Fermentation is a method that can improve the taste and nutritional value of rice noodles. Lactic acid fermentation refers to the fermentation process in which sugar is anaerobicly decomposed to produce lactic acid. Ethanol fermentation is one of the two main fermentation forms in organisms.

[0003] The change process of CO2 production during rice noodle fermentation is mainly affected by the metabolic activities of lactic acid bacteria and other microorganisms. In the early stage of fermentation: At this stage, lactic acid bacteria and other microorganisms begin to become active, carry out metabolic activities, and produce CO2. The CO2 production at this stage is relatively low, because the microorganisms have just begun to adapt to the fermentation environment and the metabolic activities are not yet sufficient. In the middle stage of fermentation: As the fermentation progresses, the metabolic activities of lactic acid bacteria and other microorganisms gradually increase, the production rate of CO2 accelerates, and the output reaches a higher level. This stage is the period of the highest CO2 production, because the metabolic activity of the microorganisms has reached its peak. If the exhaust speed is slow at this time, the CO2 accumulated in the fermentation tank will increase, resulting in an increase in the pressure in the fermentation tank, affecting the activity of lactic acid bacteria. In the late stage of fermentation: As the fermentation is nearing completion, lactic acid bacteria and other microorganisms The metabolic activity of the organisms gradually weakens, the production rate of CO2 slows down, and the output gradually decreases. The CO2 output at this stage is relatively low because most of the available substrates have been consumed. During the fermentation process, the stirring speed of the rice noodles should also change with the change of CO2 output. If the CO2 output is high and the stirring speed is slow, it will easily lead to a large amount of CO2 in the rice noodles, which will further cause small holes in the rice noodles after fermentation, affecting the taste of the rice noodles. When the CO2 output is low, if the stirring speed is too fast, the load of the motor will be increased, increasing the production cost. If the stirring speed is adjusted directly by changing the motor power, the voltage and current of the motor will become unstable, affecting the service life of the motor.

[0004] For this reason, a rice flour fermentation device is proposed. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a rice noodle fermentation device, which can freely adjust the rotation speed of a rotating shaft by controlling the extension length of an electric telescopic rod, avoid frequently adjusting the power of a motor to change the rotation speed of the rotating shaft, avoid instability of current and voltage in the motor, and ensure the service life of the motor. The rice noodles are stirred at different speeds according to the CO2 output of lactic acid bacteria in different reaction periods, so that CO2 can be eliminated as soon as possible when the output is high, and the formation of pores in the rice noodles due to the failure to discharge CO2 can be avoided, which is beneficial to the fermentation of the rice noodles.

[0039] The bottom end of the connecting rod 26 is fixedly connected with a piston 29 , and the thickness of the piston 29 is equal to the diameter of the air hole 25 .

[0040] The air outlet pipe 13 is located on the side wall outside the sealing cover 3 and is connected to an air pump 17 . The air outlet of the air pump 17 is connected to an exhaust pipe 18 . A one-way valve 19 is provided on the exhaust pipe 18 .

[0041] In this embodiment, when the electric telescopic rod 12 is extended, the rotation speed of the rotating shaft 10 is continuously accelerated, and the electric telescopic rod 12 can push the piston 29 at the bottom end of the connecting rod 26 to slide downward. When the piston 29 continues to slide downward, the number of air holes 25 connected to the vacuum pump 17 will continue to increase. At this time, the CO2 generated in the fermentation tank body 1 can be discharged through the vacuum pump 17. When the CO2 production in the fermentation tank body 1 increases, CO2 is quickly discharged through multiple air holes 25. The rotation speed of the rotating shaft 10 can be adjusted according to the change in the CO2 content, and the number of connected air holes 25 can be adjusted, which is conducive to the timely discharge of CO2.

[0042] As an embodiment of the present invention, refer to Figure 2-Figure 4 , Figure 6 A feed pipe 6 is connected to the side wall of the sealing cover 3, a thermometer 7 is also connected to the top of the sealing cover 3, a discharge pipe 5 is also connected to the bottom end of the fermentation tank body 1, and the bottom end of the rotating shaft 10 extends into the discharge pipe 5 and is fixedly connected to a spiral conveying sheet 9 that fits tightly to the inner wall of the discharge pipe 5.

When the fermentation is completed, the hydraulic telescopic rod 2 is started, and the hydraulic telescopic rod 2 can be extended. At this time, the sealing cover 3 can slide toward the top of the fermentation tank body 1, which is convenient for cleaning the fermentation tank body 1, and the cleaning effect of the fermentation tank body 1 can be improved, and the residual rice noodles can be prevented from affecting the next fermentation.

[0045] Working principle: First, the rice noodle reaction raw material is injected into the fermentation tank body 1 from the feed pipe 6. During the fermentation process, when the motor 4 is powered on, the motor 4 can drive the pulley 16 to rotate. At this time, the pulley 16 can drive the first active conical wheel 21, the second active conical wheel 24, the first driven conical wheel 11 and the second driven conical wheel 14 to rotate together through the transmission belt 20. At this time, the rotating shaft 10 at the bottom end of the second driven conical wheel 14 can drive the stirring frame 8 to rotate in the fermentation tank body 1, so that the rice noodles can fully react with the lactic acid bacteria, and the fermentation efficiency can be improved.

At this time, the inner diameters of the first active conical wheel 21 and the second active conical wheel 24 will increase. Since the length of the transmission belt 20 remains unchanged, the transmission belt 20 will squeeze the first driven conical wheel 11, and the first driven conical wheel 11 will squeeze the spring 22 to slide toward the support plate 15. At this time, the first driven conical wheel 11 will slide upward, and the distance between the first driven conical wheel 11 and the second driven conical wheel 14 will be reduced. The distance between the first driven conical wheel 11 and the second driven conical wheel 14 increases, resulting in the inner diameter of the first driven conical wheel 11 and the second driven conical wheel 14 being reduced, so that the rotation speed of the first driven conical wheel 11 and the second driven conical wheel 14 is increased. By controlling the extension length of the electric telescopic rod 12, the rotation speed of the rotating shaft 10 can be freely adjusted, and the frequent adjustment of the power of the motor 4 to change the rotation speed of the rotating shaft 10 can be avoided, and the instability of the current and voltage in the motor 4 can be avoided, and the service life of the motor 4 can be guaranteed. The rice noodles can be stirred at different speeds according to the CO2 output of the lactic acid bacteria in different reaction periods, and the CO2 can be eliminated as soon as possible when the output is high, and small holes in the rice noodles due to the failure of CO2 to be discharged can be avoided, which is conducive to the fermentation of the rice noodles;

[0047] When the electric telescopic rod 12 is extended, the rotation speed of the rotating shaft 10 is constantly accelerated, and the electric telescopic rod 12 can push the piston 29 at the bottom end of the connecting rod 26 to slide downward. When the piston 29 continues to slide downward, the number of the air holes 25 connected to the air pump 17 will continue to increase. At this time, the CO2 generated in the fermentation tank body 1 can be discharged through the air pump 17. When the CO2 production in the fermentation tank body 1 increases, the CO2 is quickly discharged through the multiple air holes 25, and further discharged from the outlet pipe 13 through the one-way valve 19 on the exhaust pipe 18. The rotation speed of the rotating shaft 10 can be adjusted according to the change of the CO2 content, and the number of the connected air holes 25 can be adjusted, which is conducive to the timely discharge of CO2.

[0048] During the fermentation process, the temperature inside the fermentation tank body 1 can be monitored in real time by the thermometer 7, so that the lactic acid bacteria can be ensured to be at a suitable survival temperature, the activity of the lactic acid bacteria can be guaranteed, and the fermentation of the rice noodles can be facilitated. After the fermentation is completed, the fermented rice noodles are discharged from the discharge pipe 5. At this time, the hydraulic telescopic rod 2 is started and the hydraulic telescopic rod 2 can be extended. At this time, the sealing cover 3 can slide toward the top of the fermentation tank body 1, which is convenient for cleaning the fermentation tank body 1, and the cleaning effect of the fermentation tank body 1 can be improved, so that the residual rice noodles can be prevented from affecting the next fermentation.
