DETAILED DESCRIPTION

[0033] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0034] The present invention discloses a fermented soybean meal hydrolysis device, such as Figure 1-14As shown, it includes a crushing and enzymolysis mechanism 100, a connecting pipe system 200 and a solid-liquid separation mechanism 300, and the crushing and enzymolysis mechanism 100 is connected to the solid-liquid separation mechanism 300 through the connecting pipe system 200. The crushing and enzymolysis mechanism 100 of the present invention includes a vertical enzymolysis kettle 101, an opening and closing filter component 102, a soybean meal crushing component 103, a drive component 106 and a temperature control component 105, wherein the temperature control component 105, the vertical enzymolysis kettle 101, the opening and closing filter component 102, and the soybean meal crushing component 103 are coaxially assembled from the outside to the inside, and the drive component 106 is transmission-connected to the soybean meal crushing component 103. The working principle and advantages of the present invention are: the present invention pre-treats (crushing and screening) the fermented soybean meal through the crushing and enzymolysis mechanism 100, that is, the soybean meal crushing component 103 is driven by the driving component 106 to operate, so that the fermented soybean meal entering the opening and closing filter component 102 is crushed, and then clean water is passed into the opening and closing filter component 102. At this time, the opening and closing filter component 102 is in an open state. At this time, the opening and closing filter component 102 is connected to the vertical enzymolysis kettle 101, and the effective components of the fermented soybean meal smoothly enter the vertical enzymolysis kettle 101, and the residue is isolated in the opening and closing filter component 102; thereafter, the opening and closing filter component 102 is controlled to be closed. At this time, the opening and closing filter component 102 is separated from the vertical enzymolysis kettle 101, and the residue is discharged. Then, the hydrolase is put into the vertical enzymolysis kettle 101, and then the connecting pipe system 200 is controlled so that the slurry in the vertical enzymolysis kettle 101 forms a cycle, and the medium is passed into the temperature control component 105. The temperature control component 105 controls the temperature of the slurry in the vertical enzymolysis kettle 101 to 50-55 ° C. After the enzymolysis is completed, the temperature of the medium is raised to above the temperature range where the hydrolase cannot survive. Like this, the hydrolase is inactivated and the enzymolysis reaction terminates. Then, the connecting pipe system 200 is controlled so that the enzymolysis product in the vertical enzymolysis kettle 101 is transported to the solid-liquid separation mechanism 300. The solid-liquid separation mechanism 300 separates the solid part and the liquid part after the enzymolysis. Finally, the obtained solid part is dried and made into a finished product. The present invention completes the entire process of enzymolysis in the crushing enzymolysis mechanism 100. Compared with existing equipment, its operability, cleaning difficulty, cost input, etc. are all improved. In summary, the present invention achieves the purpose of improving the enzymatic hydrolysis efficiency of fermented soybean meal, reduces the investment cost of equipment, makes the operation of the equipment more convenient, greatly reduces the workload of equipment cleaning, and ensures the smoothness of temperature changes during the enzymatic hydrolysis process, thereby improving the stability of the enzymatic hydrolysis product.

[0035] As a preferred embodiment of the present invention, Figure 4As shown, the temperature control assembly 105 includes a medium discharge annular pipe 1051, a medium inlet annular pipe 1052, and a plurality of vertical temperature regulating pipes 1055. The medium discharge annular pipe 1051 and the medium inlet annular pipe 1052 are spaced apart and sleeved on the outside of the vertical enzymolysis kettle 101 in a vertical downward direction. A medium discharge joint 1053 is constructed on the medium discharge annular pipe 1051, and a medium inlet joint 1054 is constructed on the medium inlet annular pipe 1052. The plurality of vertical temperature regulating pipes 1055 are arranged between the medium discharge annular pipe 1051 and the medium inlet annular pipe 1052. These vertical temperature regulating pipes 1055 are evenly arranged along the circumference of the vertical enzymolysis kettle 101, and the upper and lower ends of each vertical temperature regulating pipe 1055 are respectively connected to the medium discharge annular pipe 1051 and the medium inlet annular pipe 1052. In this embodiment, when performing enzymolysis, an aqueous medium having a temperature of 50-55° C. is passed into the medium entry joint 1054, and then uniformly supplied to all vertical thermostatic tubes 1055 through the medium entry annular tube 1052. These vertical thermostatic tubes 1055 heat the vertical enzymolysis kettle 101 until the temperature of the slurry in the vertical enzymolysis kettle 101 reaches within a predetermined range, and the aqueous medium is kept in continuous communication with each vertical thermostatic tube 1055 until the enzymolysis is completed. After the enzymolysis is completed, hot steam is passed into the medium entry joint 1054, and the hot steam transfers heat to the vertical enzymolysis kettle 101 through all vertical thermostatic tubes 1055, so that the enzymolysis product in the vertical enzymolysis kettle 101 is rapidly heated, ensuring that the hydrolytic enzyme in the enzymolysis product is rapidly inactivated. Compared with electric heating, this embodiment regulates the temperature more gently and smoothly during the enzymatic hydrolysis process, thereby avoiding the occurrence of unstable enzymatic hydrolysis products; and when the hydrolase is inactivated, it can be completed in a very short time, thereby improving the inactivation efficiency.

[0036] As a preferred embodiment of the present invention, Figure 6-8As shown, the opening and closing filter assembly 102 includes a lower fixed filter cartridge, an upper movable filter cartridge, a connecting cylinder 1021 and a vertical drive member 1027. Among them, the lower fixed filter cartridge and the upper movable filter cartridge are coaxially arranged in the vertical enzymolysis kettle 101, the lower end of the lower fixed filter cartridge is fixedly connected to the bottom wall of the vertical enzymolysis kettle 101, the lower end of the upper movable filter cartridge is movably extended into the lower fixed filter cartridge by the upper end of the lower fixed filter cartridge, and the area where the lower fixed filter cartridge and the upper movable filter cartridge overlap with each other is in a closed state. The connecting cylinder 1021 of this embodiment is coaxially constructed at the upper end of the upper movable filter cartridge, the upper end of the connecting cylinder 1021 is movably extended from the upper end of the vertical enzymolysis kettle 101, and a connecting wing 1024 is constructed on the upper peripheral wall of the connecting cylinder 1021. The vertical drive member 1027 is connected to the connecting cylinder 1021 through the connecting wing 1024. The vertical drive member 1027 is generally a pneumatic cylinder, an electric cylinder or an oil cylinder. An upper end cap 1028 is detachably connected to the upper end of the connecting cylinder 1021. A feeding connector 1029 is constructed on the upper end cap 1028. Fermented soybean meal is fed into the open / close filter assembly 102 through the feeding connector 1029. The lower fixed filter cartridge of this embodiment includes a plurality of lower vertical plates 1025, which are evenly arranged along the circumference of the vertical enzymolysis kettle 101. A lower filter screen 1026 is connected between adjacent lower vertical plates 1025. Thus, the spaced lower vertical plates 1025 are connected by the lower filter screen 1026, forming a cylindrical structure, allowing the lower fixed filter cartridge to perform filtering operations through the lower filter screen 1026. The upper movable filter cartridge of this embodiment includes a plurality of upper vertical plates 1022, which are evenly arranged along the circumference of the vertical enzymolysis kettle 101. An upper filter screen 1023 is connected between two adjacent upper vertical plates 1022. In this way, the separated upper vertical plates 1022 are connected by the upper filter screen 1023, forming a cylindrical structure, allowing the upper movable filter cartridge to perform filtering operations through the upper filter screen 1023. Moreover, when the lower fixed filter cartridge and the upper movable filter cartridge are inserted into each other, the lower vertical plates 1025 block the corresponding upper filter screen 1023, and the upper vertical plates 1022 block the corresponding lower filter screen 1026, thereby isolating the overlapping portion of the lower fixed filter cartridge and the upper movable filter cartridge from the vertical enzymolysis kettle 101. The working principle and advantages of this embodiment are: when the fermented soybean meal is crushed and the crushed soybean meal is subsequently supplied to the vertical enzymolysis kettle 101, the vertical driving member 1027 is controlled to move, so that the connecting cylinder 1021 drives the upper movable filter cylinder to move upward in the vertical direction, so that the upper end of the lower fixed filter cylinder and the lower end of the upper movable filter cylinder are inserted and overlapped. In this way, after clean water is passed into the connecting cylinder 1021, the clean water drives the crushed fermented soybean meal through the upper filter screen 1023 or the lower filter screen 1026 into the vertical enzymolysis kettle 101.After the mass transfer of the opening and closing filter assembly 102 and the vertical enzymolysis kettle 101 is completed, the vertical driving member 1027 is controlled to move so that it drives the upper movable filter cartridge to move downward by connecting tube 1021, until the upper movable filter cartridge completely overlaps with the lower fixed filter cartridge. At this time, the opening and closing filter assembly 102 and the vertical enzymolysis kettle 101 are in the state of being cut off. Then, the residue in the opening and closing filter assembly 102 is emptied and discharged, and cleaning water can be injected into the opening and closing filter assembly 102, while controlling the soybean meal crushing assembly 103 to move so that cleaning water cleans the soybean meal crushing assembly 103 in the opening and closing filter assembly 102 and the opening and closing filter assembly 102. The opening and closing filter assembly 102 of the present embodiment provides place for the crushing of soybean meal, and the effective component of the soybean meal after crushing and residue (difficult to crush broken material, large particle slag, the rest of the non-soybean meal produced external impurities) can be separated, so that the effective component of soybean meal can smoothly enter in the vertical enzymolysis kettle 101.

The assembly rod 1031 is rotatably mounted within the open-close filter assembly 102, and the axis of the assembly rod 1031 coincides with the axis of the connecting cylinder 1021. The plurality of crushing blades 1032 are vertically spaced apart and mounted on the assembly rod 1031. The drive assembly 106 of this embodiment includes a drive motor 1061, a first transmission wheel 1062, a second transmission wheel 1063, and a transmission belt 1064. The drive motor 1061 is disposed below the vertical enzymolysis reactor 101. The first transmission wheel 1062 is coaxially mounted on the output shaft of the drive motor 1061. The second transmission wheel 1063 is coaxially mounted below the assembly rod 1031. The first and second transmission wheels 1062, 1063 are connected by a transmission belt 1064. In this embodiment, the driving motor 1061 is controlled to rotate, so that the assembly rod 1031 is driven in the transmission direction of the pulley. During the rotation, the assembly rod 1031 drives all the crushing blades 1032 thereon to rotate and crush the fermented soybean meal.

An abutment surface 1043 is formed at the upper end of the assembly 1041 and at the outer edge of the slag guide port 1044. When the upper movable filter cartridge is driven downward, the lower limit of the upper movable filter cartridge is when the lower end of the upper movable filter cartridge abuts against the abutment surface 1043. In this embodiment, a slag passage hole 1045 is formed at the center of the slag guide port 1044. A slag guide sleeve 1046 is constructed at the lower end of the assembly 1041.

When the open-close filter assembly 102 needs to be discharged, the assembly rod 1031 is driven to rotate backward. During the reverse rotation, the spiral slag guide blades 1033 convey the residue accumulated at the bottom of the open-close filter assembly 102 into the slag guide sleeve 1046, where it is then discharged through the slag discharge pipe 1047.

The annular liquid pipe 216 is connected to multiple oblique flow pipes 217, which are evenly connected to the lower end of the vertical enzymolysis kettle 101 along the circumference of the vertical enzymolysis kettle 101. A plurality of oblique flow ports 218 are evenly opened on the bottom wall of the vertical enzymolysis kettle 101 along its axis. The number of oblique flow ports 218 is the same as the number of oblique flow pipes 217, and the end of each oblique flow pipe 217 is connected to the corresponding oblique flow port 218. In this embodiment, a first control valve 204 is installed on the first liquid inlet pipe 203, a fourth control valve 209 is installed on the liquid inlet hose 208, a second control valve 207 is installed on each liquid inlet branch pipe 206, a third control valve 212 is installed on the third liquid inlet pipe 211, a discharge control valve 214 is installed on the discharge pipe 213, and a liquid outlet control valve 215 is installed on the liquid outlet main pipe 210 and at a position between the third liquid inlet pipe 211 and the discharge pipe 213. When it is necessary to transport the crushed soybean meal in the open and close filter assembly 102 to the vertical enzymolysis kettle 101 and add water to the vertical enzymolysis kettle 101, open the first control valve 204 and the fourth control valve 209, close the other valves, and supply pressurized clean water to the connecting tube 1021 through the first liquid inlet pipe 203, the second liquid inlet pipe 205 and the liquid inlet hose 208. The clean water enters the lower part of the open and close filter assembly 102 and carries the crushed soybean meal into the vertical enzymolysis kettle 101. When the enzymolysis operation is performed, the second control valve 207 on one or more liquid inlet branches 206 is opened, the liquid outlet control valve 215 is opened, and the other valves are closed. In this way, the pressure pump 201 pumps the slurry at different positions on the upper part of the vertical enzymolysis kettle 101 to the annular liquid pipe 216, and then evenly distributes it to each inclined flow pipe 217. Then, it is injected obliquely from the lower end of the vertical enzymolysis kettle 101 through the inclined flow pipe 217, so that the slurry moves gradually from bottom to top toward the upper part of the vertical enzymolysis kettle 101 in the form of a vortex, thereby forming a circulation, ensuring that the effective components in the slurry are fully in contact with the hydrolytic enzyme and are repeatedly decomposed by the hydrolytic enzyme. In addition, the vortex slurry can effectively avoid the occurrence of reaction dead corners.The present embodiment can open at least one liquid inlet branch 206 according to demand so that the slurry in the vertical enzymolysis kettle 101 realizes the circulation under different depths, and generally all liquid inlet branches 206 are opened, so that the effect of circulation and mixing is best. The present embodiment can also open all liquid inlet branches 206 below the liquid level according to the liquid level in the vertical enzymolysis kettle 101, so as to avoid the occurrence of a certain liquid inlet branch 206 sucking empty situation. After hydrolysis is complete, open the third control valve 212 and the discharge control valve 214, close other valves, and the liquid in the vertical enzymolysis kettle 101 passes through the inclined flow pipe 217, the annular liquid pipe 216, the third liquid inlet pipe 211, the liquid inlet main pipe 202, the pressure pump 201 and the discharge pipe 213 in sequence, and finally enters into the solid-liquid separation mechanism 300.

[0040] As a preferred embodiment of the present invention, Figure 12-14As shown, the solid-liquid separation mechanism 300 includes a vertical separation kettle 301, an isolated liquid drainage assembly, a disc filter press seat 306, a vertical transmission screw 310, and a third transmission wheel 311. The isolated liquid drainage assembly is disposed within the vertical separation kettle 301, the disc filter press seat 306 is disposed between the vertical separation kettle 301 and the isolated liquid drainage assembly, the disc filter press seat 306 is connected to a transmission seat 309 via a vertical guide rod 308, and the transmission seat 309 is disposed above the vertical separation kettle 301. The vertical transmission screw 310 is threadedly connected to the transmission seat 309, and the lower end of the vertical transmission screw 310 is rotationally connected to the vertical separation kettle 301. The third transmission wheel 311 is coaxially assembled on the vertical transmission screw 310. In this embodiment, the third transmission wheel 311 is driven to rotate, so that the vertical transmission screw 310 is driven to rotate, and the vertical transmission screw 310 drives the transmission seat 309 to move downward in the vertical direction; the transmission seat 309 drives the disc filter press seat 306 through the vertical guide rod 308 to filter the enzymatic hydrolyzed product in the vertical separation kettle 301, and the liquid filtered out enters the isolated drainage component and is then extracted; the solid obtained by the filter press is removed from the vertical separation kettle 301 for subsequent drying operations. The isolated drainage component of this embodiment includes a filter tube 303 and a liquid extraction pipe 304 arranged in sequence from the outside to the inside, with a liquid collection area 305 formed between the two, and the liquid filtered out enters the liquid collection area 305 through the filter tube 303. The upper end of the filter tube 303 is fixedly connected to the top wall of the vertical separation kettle 301. The lower end of the vertical separation kettle 301 is detachably connected to the lower connecting cover 302. The lower end of the filter tube 303 contacts the upper end surface of the lower connecting cover 302. The lower end of the liquid extraction tube 304 is higher than the lower end of the filter tube 303. The upper end of the liquid extraction tube 304 extends out of the vertical separation kettle 301 and is connected to the discharge pipe 312. In this embodiment, by suctioning the discharge pipe 312, the liquid in the liquid collection area 305 is extracted through the liquid extraction tube 304. In this embodiment, filtrate sections 307 are uniformly configured along the circumference of the disc-shaped filter press seat 306. Each filtrate section 307 is composed of multiple stacked hard filter screens. During the filtration operation of the disc-shaped filter press seat 306, some liquid flows out of the filtrate section 307 and then enters the liquid collection area 305 through the filter tube 303. This prevents the gradual increase in the density of the solid material during the filtration process, which would lead to poor water conduction in the filter tube 303. The water discharged from the filtration can indirectly enter the filter tube 303 through the filtrate section 307. After the filtration is completed and the liquid is completely extracted, the lower connecting cover 302 is opened to remove the solid material from the vertical separation kettle 301.
