Description

Technical Field

[0001] The invention relates to the technical field of enzymatic hydrolysis and fermentation, in particular to an improved red yeast rice flour enzymatic hydrolysis method and device and application thereof in rice starch fat substitution. Background Art

[0002] Red yeast rice flour is a traditional Chinese food and medicine. It is made from fermented early rice. It is primarily produced by a mixed culture of various ester-producing microorganisms, including Monascus. Fermentation of the red yeast rice flour requires an enzymatic hydrolysis unit.

[0003] The Chinese patent with the existing authorization announcement number CN108841480B discloses a fermentation device, including an enzymolysis tank, a detection unit and an exhaust unit. The detection unit includes a disc fixed on the outer wall of the enzymolysis tank. A rotating shaft is connected to the enzymolysis tank at the same level as the disc. A first torsion spring is installed between the rotating shaft and the inner wall of the enzymolysis tank. The rotating shaft passes through the side wall of the enzymolysis tank and the disc. A pointer is fixed to the end of the rotating shaft outside the enzymolysis tank. A pull rope is wrapped around the middle of the rotating shaft and the end of the pull rope is fixed on the rotating shaft. A detection block is fixed to the lower end of the rope; the exhaust unit includes a plurality of convex teeth fixed on the rotating shaft, the convex teeth are evenly distributed along the circumference of the rotating shaft, and a gear is rotatably connected on the inner wall of the enzymolysis tank. The convex teeth can engage with the gear when rotating. A second torsion spring is installed between the gear and the inner wall of the enzymolysis tank. A through hole is eccentrically provided on the gear, and an air outlet matching the through hole is provided on the side wall of the enzymolysis tank at the gear; this invention keeps the temperature during the fermentation process warm, avoids the temperature in the enzymolysis tank being too high or too low, and solves the problem of real-time monitoring of the fermentation degree.

[0004] However, the enzymatic hydrolysis device has the following defects when used:

[0005] 1. When fermenting the raw materials for synthesizing red yeast rice flour, the existing enzymatic hydrolysis device requires a stirring structure to stir the red yeast rice flour raw materials and the fermentation liquid, so as to improve the mixing of the raw materials and the fermentation liquid and the efficiency of fermentation by stirring. When stirring to improve the fermentation efficiency, the operation of the stirring operation will generate stirring heat, the decomposition of the fermentation bacteria will generate biological heat, and a large amount of gas will be generated during the fermentation process. At this time, the enzymatic hydrolysis tank needs to be pressure-relieved to ensure the safety of the fermentation operation. However, when the pressure relief operation is actually carried out, an additional structure is required to complete the pressure relief operation, and the operation is complicated. At the same time, pressure relief is a process in which the air pressure is constantly changing, and the flow of gas requires a certain amount of time. At this time, it is easy for the gas to fail to move to one side of the pressure relief port in time, and multiple pressure reliefs are performed, which affects the fermentation effect (external gas can easily enter the interior of the enzymatic hydrolysis tank);

[0006] 2. To improve efficiency, existing enzymatic hydrolysis equipment requires stirring and mixing the raw materials and fermentation liquid during red yeast rice flour fermentation. However, this traditional solution generates significant heat during continuous stirring, leading to a sharp increase in internal heat within the enzymatic hydrolysis tank and poor fermentation results. Furthermore, this continuous stirring damages the raw materials and fermentation liquid, affecting the quality of the finished product. Summary of the Invention

[0045] The present invention also provides application of the improved red yeast rice flour enzymatic hydrolysis device in rice starch fat substitution.

[0046] Compared with the existing technology, one or more of the above technical solutions have the following beneficial effects:

[0047] 1. In the application of the improved red yeast rice flour enzymolysis method and device and in rice starch fat substitute, when the raw materials for synthesizing red yeast rice flour are fermented, the servo motor can be used to drive the driving shaft to rotate forward, drive the pressure relief piston to move back and forth, open the pressure relief through hole inside the pressure relief cylinder, and automatically realize the pressure relief operation of the gas inside the enzymolysis tank, thereby ensuring the safety of the raw materials during fermentation. At the same time, the above method can perform the pressure relief operation for a long time, leaving enough time for the flow of gas inside the enzymolysis tank, ensuring that the air pressure at various positions inside the enzymolysis tank tends to be consistent, and the fermentation process is more stable. In addition, the driving shaft that drives the pressure relief piston to operate can stir the raw materials and the fermentation liquid during its forward or reverse rotation, thereby ensuring the efficiency of the raw materials during fermentation;

[0048] 2. In the application of the improved red yeast rice flour enzymolysis method and device and in rice starch fat substitute, during the process of stirring and fermenting the raw materials and fermentation liquid inside the enzymolysis tank, the rotation of the lower rotating shaft drives the stirring blades and the middle spiral blades installed on its outside to rotate, and continuously stirs the fermentation liquid and the raw materials in the external and middle position, ensuring that the raw materials and fermentation liquid in the middle position can be continuously and quickly moved to the side of the enzymolysis tank heated, and improve the contact time with the heated side of the enzymolysis tank. On the other hand, the rotation of the lower rotating shaft can drive the raw materials and fermentation liquid close to the heated side to rotate intermittently (through the eccentric spiral blades), leaving enough time for the contact and reaction of the raw materials, fermentation liquid and heating module, while reducing the probability of continuous stirring causing damage to the raw materials and internal components of the fermentation liquid in the heated state, and improving the quality of the material after fermentation is completed;

[0049] 3. In the improved red yeast rice flour enzymolysis method and device and its application in rice starch fat substitution, when the excess gas inside the enzymolysis tank is depressurized, the setting of the sealing ring can be used as a sealing part of the sealing rod, and a sealing process is performed when pressure relief is not required, thereby reducing the probability of gas leakage inside the enzymolysis tank and improving the sealing effect during fermentation. On the other hand, when the pressure relief operation is performed, the sealing rod inside the sealing ring will be moved out from the inside. At this time, the space inside the sealing ring serves as a pressure relief vent, and its larger cross-section can improve the efficiency of depressurizing the gas inside the enzymolysis tank;

[0050] 4. In the improved red yeast rice flour enzymatic hydrolysis method and device and its application in rice starch fat substitution, during the process of relieving the pressure of the gas inside the enzymatic hydrolysis tank, the pressure relief piston, on the one hand, uses the pressure relief through-hole opened on its side as a channel for the flow of excess gas, ensuring that the pressure-relieved gas will move to the side of the sealing ring for pressure relief. On the other hand, the extrusion force of the pressure relief piston during reciprocating movement can also accelerate the speed at which the pressure-relieved gas moves to the side of the sealing ring, thereby increasing the speed at which the gas inside the enzymatic hydrolysis tank is transported to the outside for pressure relief.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0073] Example 1

The enzymolysis tank 10 is installed on the inner side of the support base 20. A plurality of heating components 30 are installed at the eccentric position of the bottom of the enzymolysis tank 10. The heating components 30 extend to the interior of the enzymolysis tank 10. The interior of the enzymolysis tank 10 is installed with an automatic enzymolysis pressure relief mechanism 40 extending to the outside. The automatic enzymolysis pressure relief mechanism 40 includes a forward and reverse assembly 50. The forward and reverse assembly 50 is installed on the inner top of the enzymolysis tank 10. The forward and reverse assembly 50 extends to the enzyme. A reciprocating pressure relief assembly 60 is installed on the top of the enzymatic hydrolysis tank 10 and on one side of the bottom of the forward and reverse assembly 50. The reciprocating pressure relief assembly 60 is installed on the inner wall of the enzymatic hydrolysis tank 10 and extends to the outside of the enzymatic hydrolysis tank 10; an intermittent stirring assembly 70 is installed on the bottom and outside of the forward and reverse assembly 50 and extends to the bottom of the enzymatic hydrolysis tank 10. The intermittent stirring assembly 70 is movably connected to the enzymatic hydrolysis tank 10 and is arranged on the side of the heating assembly 30.

[0075] In the present invention, a partition 101 is installed on the inner top of the enzymolysis tank 10, and the top of the partition 101 is movably connected to the forward and reverse assembly 50, and a feed pipe 102 is installed at the eccentric point inside the partition 101, and the feed pipe 102 extends to the outside of the enzymolysis tank 10, wherein two air pressure detection modules 103 are also installed at the eccentric point inside the partition 101, and the air pressure detection module 103 extends to the outside of the enzymolysis tank 10, and a reciprocating pressure relief assembly 60 is movably provided at the eccentric point of the bottom of the partition 101, wherein the eccentric point of the bottom of the enzymolysis tank 10 is connected to a discharge pipe 104, and the discharge pipe 104 is arranged on the side of the heating assembly 30, and a temperature and liquid level detection sensor 105 is installed on the inner wall of the enzymolysis tank 10.

Afterwards, when the raw materials are fermented, the heating component 30 is started to operate, and the raw materials in the fermentation process are heated to improve the efficiency of fermenting the raw materials.

Among them, the air pressure detection module 103 can detect the air pressure intensity inside the enzymolysis tank 10. When the air pressure inside the enzymolysis tank 10 is too high, the forward and reverse component 50 rotates forward, driving the reciprocating pressure relief component 60 to operate, and the gas inside the enzymolysis tank 10 is pressure-relieved, ensuring that the air pressure inside the enzymolysis tank 10 tends to a stable state, thereby improving the effect and efficiency of fermenting the raw materials.
