Description

Technical Field

[0001] The utility model belongs to the technical field of wheat protein preparation equipment, in particular to an enzymolysis reactor. Background Art

[0002] Wheat contains about 13% protein, which is mainly composed of albumin, globulin, alcohol-soluble protein and glutenin. Wheat gluten protein mainly contains gliadin and glutenin, collectively known as storage protein (accounting for 80% of wheat protein on a dry basis). Because gliadin is ductile and glutenin is elastic, they can form a network structure with water, thus having unique physical properties such as excellent viscoelasticity, extensibility, water absorption, liposuction emulsification, film forming properties and a light and mellow aroma or a slight cereal flavor.

[0003] The patent document with publication number CN102907559A discloses a prior art wheat protein enzymatic hydrolysis method: a preparation method for hydrolyzing wheat protein. In the present invention, 10 to 20 parts of papain and 5 to 10 parts of thermophilic protease are weighed and added to the interior of the reactor in step S2; trypsin is added to the mixed solution prepared in step S4, and the solution is heated and stirred. When the temperature is heated to 40°C, the mixed solution is continued to undergo a hydrolysis reaction; when the pH is adjusted to 8.5, 1.5 to 3 parts of a composite enzyme preparation are added to the system, and it is started to undergo hydrolysis. Trypsin, papain, thermophilic protease and composite enzyme preparation are added, so that in the process of hydrolyzing wheat protein, different enzymes can fully react with wheat gluten protein powder.

[0004] It can be seen that the hydrolyzed wheat protein mixture contains a large amount of biological enzymes, which must be inactivated before use. However, the existing technology requires taking out the wheat protein mixture when inactivating the enzymes and then setting up another reactor (or reaction container) to inactivate the enzymes at high temperature. The inactivation treatment cannot be performed directly in the hydrolysis reaction container, which increases the cost of production equipment. Utility Model Content

By setting the working time of the motor, the amount of wheat flour added is determined, thereby ensuring quantitative feeding of wheat flour. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The heat preservation mechanism 9 includes: a heat inlet 91, a cold outlet 92, a covering shell 93, and a heat exchange chamber 94; the covering shell 93 is covered on the outside of the outer shell of the kettle 1, and a gap is provided between the covering shell 93 and the outer shell of the kettle 1 to form a heat exchange chamber 94, and a support is provided inside the heat exchange chamber 94 to connect the covering shell 93 and the kettle 1; the covering shell 93 is provided with two pipeline interfaces and the inside of the heat exchange chamber 94 is connected to the heat inlet 91 and the cold outlet 92 respectively.

[0030] The heat inlet 91 and the cold outlet 92 are arranged on different sides of the covering shell 93 .

[0031] The driving mechanism 5 includes: a motor 51, a reducer 52, a driving wheel 53, and a driven wheel 54; a reducer 52 is fixed to the top of the kettle 1 through a bracket, the input end of the reducer 52 and the output end of the motor 51 are coaxially fixed, the motor 51 is fixed on the outer shell of the reducer 52, and a driving wheel 53 is fixed to the output shaft of the reducer 52. The rotating tube 6 is provided with a driven wheel 54 at the same height as the driving wheel 53, and the driving wheel 53 and the driven wheel 54 are connected by a chain or belt transmission.

[0032] The kettle 1 is provided with a reinforcing hoop frame 13 of a frame structure on the outer hoop.

[0033] A powder conveying mechanism 7 is provided at the powder filling port 3, and the powder conveying mechanism 7 includes: a powder feeding port 71, a lower inflection port 72, a lifting pipe 73, and a discharge branch pipe 74; the lifting pipe 73 is an inclined straight pipe, and the lifting pipe 73 is fixed to the reinforcing hoop frame 13 by a plurality of hangers 15 (for the sake of simplicity of the drawing, only one group of hangers 1 is shown in the figure); the lowest position of the lifting pipe 73 is connected to a pipeline through a lower inflection port 72 of a curved pipe structure, and the end of the pipeline is the powder feeding port 71, and the end of the lifting pipe 73 away from the lower inflection port 72 is provided with a discharge branch pipe 74 extending toward the powder filling port 3, and the lower end of the discharge branch pipe 74 is located directly above the powder filling port 3.

[0034] In order to ensure quantitative addition when adding wheat flour (this quantitative addition is interval quantitative addition rather than precise quantitative addition), a propeller 75 is built into the lifting pipe 73, and the upper port of the propeller 75 is located above the discharge branch pipe 74. A lifting motor 76 is fixed to the upper end of the lifting pipe 73, and the output end of the lifting motor 76 is coaxially connected to the propeller 75.

[0035] A thermometer 12 is fixed on the top of the kettle 1 , and a temperature detection probe of the thermometer 12 is located inside the kettle 1 .

[0036] Brief description of the usage process:

[0037] When in use, the motor 51 and the lifting motor 76 are connected to an external power supply with a switch, the heat inlet 91 is connected to a heat source gas circuit or a heat source water circuit with a valve, the cold outlet 92 is connected to a recovery pipeline, and the high-temperature pipe 4 is used to fix the high-temperature gas pipe with a valve;

[0038] The flour feeding port 71 is used to connect the flour conveying pipeline. Due to the weight, the flour will accumulate at the lower inflection point 72. Since the propeller 75 is provided in the lifting pipe 73, the lifting pipe 73 will be sealed in disguise. The flour at the lower inflection point 72 cannot directly enter the upper part of the lifting pipe 73.

[0039] Then, the lifting motor 76 is started to rotate, and the lifting motor 76 drives the propeller 75 to rotate. The propeller 75 lifts the wheat flour at the lower inflection 72 and transports it to the lifting pipe 73, and then discharges it to the powder filling port 3 through the discharge branch pipe 74. The amount of wheat flour added is determined by setting the working time of the motor 76 (the amount of wheat flour added is proportional to the working time of the motor 76, and the amount of wheat flour added can be calculated by the single-hour delivery amount), and then water and reaction enzyme liquid are added through the water filling port 2;

[0040] Then, the valve with the heat inlet 91 is opened, and the heat inlet 91 delivers the heat source to the heat exchange chamber 94, and the heat exchange chamber 94 and the kettle 1 perform heat exchange, raising the temperature in the kettle 1 to the enzymolysis temperature;

[0041] Then the motor 51 is started to rotate, and the motor 51 drives the driving wheel 53 to rotate through the reducer, and the driving wheel 53 drives the driven wheel 54 and the rotating tube 6 to rotate as a whole, and then the stirring paddle 14 on the rotating tube 6 rotates to mix the wheat flour, water and enzyme solution, and under the support of the heat preservation mechanism 9, the wheat flour undergoes a hydrolysis reaction to form hydrolyzed wheat protein. After a period of reaction, a turbid liquid containing hydrolyzed wheat protein is formed in the kettle 1. At this time, the turbid liquid needs to be enzyme-inactivated and then discharged for the next step;

[0042] When inactivating the enzyme, the valve at the high-temperature tube 4 is opened, and the high-temperature gas enters the rotating tube 6 from the high-temperature tube 4 and is transmitted to the gas distribution pipe 61 at the lower end of the rotating tube 6. The gas distribution pipe 61 disperses the high-temperature airflow to each group of rotating empty tubes 62. The rotating empty tubes 62 disperse the airflow to each group of air jet holes 63. The air jet holes 63 spray out the high-temperature airflow to generate a large number of high-temperature bubbles, and these high-temperature bubbles are dispersed under the rotation of the rotating tube 6 to be evenly distributed in the kettle 1. The high-temperature bubbles contact the water in the kettle 1 to generate a large amount of high-temperature steam, which inactivates the enzyme in the water at high temperature and completes the enzyme inactivation process. After the enzyme inactivation process is completed, the turbid liquid is sent from the discharge port 11 to the next centrifugal process to centrifuge the wheat protein.
