Description

Technical Field

[0001] The utility model relates to the technical field of dairy product processing, in particular to a plant milk enzymatic hydrolysis screw extruder and a plant milk production line. Background Art

[0002] Plant milk is a beverage made from plant seeds or fruits containing protein and fat. Some plant seeds or fruit raw materials can be made into beverages by mechanically crushing and mixing with liquid, such as soy milk, which is made by mixing soy milk with water after breaking the wall. Some plant seeds or fruit raw materials cannot be directly crushed by mechanical crushing to form beverages for their own reasons. For example, oats are high in fiber and have relatively coarse particles, so they need to go through enzymatic hydrolysis and other processes before being blended to make beverages. Enzymatic hydrolysis is a key technology in the production of plant milk. Enzymatic hydrolysis is a way of converting carbohydrates and proteins in plant seeds or fruit raw materials into water-soluble nutrients. It is an important part of production process innovation and affects the flavor of the finished product. The more complete the enzymatic hydrolysis, the more nutrients the plant milk produced will have and the better the flavor.

[0003] Enzymatic hydrolysis reaction is the core of the enzymatic hydrolysis process. The enzymatic hydrolysis reaction is to react the selected enzyme and raw materials in a reactor, control the temperature, pH value, enzyme dosage and time and other parameters in the reactor, so as to utilize the catalytic effect of the enzyme to decompose large molecules into small molecules.

[0004] The commonly used reactor in the prior art is a reaction tank, which is usually equipped with a stirring device to speed up the enzymatic hydrolysis and promote the uniformity of the enzymatic hydrolysis reaction of the raw materials. The enzymatic hydrolysis is performed in a reaction tank with a stirring device. Due to the mechanical structure of the reaction tank and the stirring device, the speed of the stirring device is generally set within 200 rpm. The enzymatic hydrolysis reaction of the enzyme and the raw material in the reaction tank takes a long time to complete. If the reaction time is insufficient, the enzymatic hydrolysis of the raw material is incomplete, and the quality of the produced plant milk will be affected. Utility Model Content

[0005] In view of the technical problems of long enzymatic hydrolysis time and low homogenization level of raw material enzymatic hydrolysis in the prior art, the utility model provides a plant milk enzymatic hydrolysis screw extruder and a plant milk production line to accelerate the enzymatic hydrolysis reaction speed and improve the homogenization level of raw material enzymatic hydrolysis.

[0006] The utility model provides a plant milk enzymolysis screw extruder, comprising an enzymolysis section, the enzymolysis section comprising a sleeve and a screw assembly arranged in the sleeve, the screw assembly being connected to a driving member for driving the screw assembly to rotate, one end of the sleeve being connected to a solid feeder for sealingly conveying solid materials into the sleeve and a liquid feeder for sealingly conveying liquid materials into the sleeve, the other end of the sleeve being provided with a discharge port, the discharge port being provided with a first valve, a second valve being provided between the solid feeder and the sleeve, and a third valve being provided between the liquid feeder and the sleeve.

[0007] The solid feeder conveys the solid material into the sleeve in a closed manner, and the liquid feeder conveys the liquid material into the sleeve in a closed manner. The space in the sleeve is occupied by the solid material and the liquid material, the space is reduced, and the pressure in the sleeve is increased. The amount of material entering the sleeve is controlled to control the pressure value in the sleeve. Under a high pressure environment, due to the extrusion of the solid material and the liquid material by the air, the contact effect of the enzyme and the solid small molecules is better. Under high pressure, the material flow rate is faster, and the enzyme and the solid material are contacted and reacted more quickly and completely, so the enzymolysis reaction speed is faster. In addition, due to the shape and structural characteristics of the extruder with a small width and a large length, the mixing of the solid material and the liquid material is more uniform under the high-speed rotation of the screw assembly, the movement speed of the solid material and the liquid material is faster, and the contact of the enzyme with the unused solid material is more frequent, and the complete enzymolysis reaction of the solid material is achieved in a shorter time. The utility model performs an enzymolysis reaction of the solid material in the sleeve of the extruder under a suitable pressure, so that the enzymolysis reaction speed is faster and the production efficiency is improved.

[0008] Further, the sleeve is connected with a first supercharger, and a pressure sensor is arranged in the sleeve. In production, it is necessary to balance and control the relationship between the solid materials and liquid materials delivered to the sleeve and the pressure environment of the enzymolysis in the sleeve. The more solid materials and liquid materials there are, the greater the pressure in the sleeve. One is that the solid materials and liquid materials will produce a blocking force on the rotation of the screw, and the other is that the closed conveying pressure of the solid feeder and the liquid feeder increases. Another is that when the material delivery reaches a suitable amount, the pressure in the sleeve cannot be further increased to increase the enzymolysis reaction speed. The sleeve is connected with a first supercharger. After the solid materials and liquid materials are delivered into the sleeve, the first supercharger is adjusted to rush air into the sleeve to increase the pressure in the sleeve, thereby increasing the enzymolysis reaction speed. In addition, the pressure in the sleeve is monitored by setting a pressure sensor. The first supercharger stops supercharging after supercharging to a suitable pressure.

[0009] Furthermore, a heating element is arranged outside the sleeve. When the screw rotates at high speed, a certain amount of heat is generated to increase the temperature inside the sleeve, thereby increasing the enzymatic hydrolysis reaction speed. The heating element is arranged outside the sleeve, and heat is provided by the heating element to make the enzymatic hydrolysis reaction environment inside the sleeve reach the optimal reaction temperature, thereby increasing the enzymatic hydrolysis reaction speed.

[0010] Furthermore, the screw assembly is a twin-screw structure, and the thread grooves of the two screws are engaged with each other. The twin-screw structure has a better extrusion effect under high-speed rotation, which can make the enzymatic reaction effect better and the enzymatic reaction speed faster.

[0011] Furthermore, the solid feeder includes a first tank body and a spiral feeding mechanism, one end of the spiral feeding mechanism is connected to the discharge port of the first tank body, the other end of the spiral feeding mechanism is connected to a solid feeding pipe, a second valve is arranged on the solid feeding pipe, and the solid feeding pipe is connected to the sleeve. The spiral feeding mechanism transports the solid material into the sleeve, and during the spiral feeding process of the spiral feeding rod, the solid material fills the air in the spiral feeding rod and the solid feeding pipe, thereby ensuring a closed feeding environment, thereby ensuring the pressure environment in the sleeve.

[0012] Furthermore, a solid feeder is arranged at the upper part of the sleeve, a solid feeder pipe is connected to the lower part of the solid feeder, one end of the solid feeder pipe away from the solid feeder is connected to the sleeve, a second valve is arranged at the solid feeder pipe, and a second booster is arranged at the upper part of the first tank body. Solid materials flow into the sleeve from top to bottom, and the solid materials fill the solid feeder pipe to ensure a closed feeding environment, thereby ensuring the pressure environment in the sleeve.

[0013] Furthermore, the liquid feeder includes a second tank body and a liquid pump, one end of the liquid pump is connected to the second tank body, the other end of the liquid pump is connected to the liquid feed pipe, the third valve is arranged on the liquid feed pipe, and the liquid feed pipe is connected to the sleeve. The liquid fills the liquid feed pipe to ensure a closed feeding environment, thereby ensuring the pressure environment in the sleeve.

[0014] Furthermore, a pressure relief valve is provided on the wall of the sleeve. When the pressure in the sleeve is relatively high or needs to be adjusted, the pressure is relieved through the pressure relief valve; or when the enzymatic hydrolysis reaction is completed and the material in the sleeve is output from the first valve, the pressure is first relieved through the pressure relief valve and then the first valve is opened.

[0015] Furthermore, a temperature sensor is provided in the sleeve to monitor the temperature in the sleeve, and adjust the temperature in the sleeve by turning on or off the heating element to ensure that the ambient temperature in the sleeve is the optimal reaction temperature.

[0016] On the other hand, the utility model provides a plant milk production line, including a plant milk enzymatic hydrolysis screw extruder, the front end of a solid feeder is connected to a crusher for crushing solid materials into powder, and the rear end of the extruder is connected to a filtering device.

[0017] The beneficial effects of the utility model are:

[0018] The utility model performs enzymolysis reaction of solid materials in the sleeve of the extruder under the adjustment to the appropriate pressure, so that the enzymolysis reaction speed is faster and the production efficiency is improved. The solid feeder conveys the solid materials into the sleeve in a closed manner, and the liquid feeder conveys the liquid materials into the sleeve in a closed manner. The space in the sleeve is occupied by the solid materials and the liquid materials, the space is reduced, and the pressure in the sleeve is increased. The quantity of materials entering the sleeve is controlled to control the pressure value in the sleeve. Under a high pressure environment, due to the extrusion of the solid materials and the liquid materials by air, the contact effect of the enzyme and the solid small molecules is better. Under high pressure, the material flow speed is faster, and the enzyme and the solid materials are contacted and reacted more quickly and completely, so the enzymolysis reaction speed is faster. In addition, due to the shape and structural characteristics of the extruder with a small width and a large length, the mixing of the solid materials and the liquid materials is more uniform under the high-speed rotation of the screw, the movement speed of the solid materials and the liquid materials is faster, and the contact of the enzyme with the unused solid materials is more frequent, so that the complete enzymolysis reaction of the solid materials is achieved in a shorter time.

[0019] The sleeve is connected to a first supercharger and a pressure sensor. After the solid material and the liquid material are transported into the sleeve, the first supercharger is adjusted to flush air into the sleeve to increase the pressure in the sleeve to a suitable pressure, thereby increasing the enzymatic reaction speed.

[0026] Embodiment 1

[0027] like Figure 1 , 2 As shown, the utility model provides a plant milk enzymatic hydrolysis screw extruder, including an enzymatic hydrolysis section, the enzymatic hydrolysis section including a sleeve 1 and a screw assembly arranged in the sleeve 1, the screw assembly is connected to a driving member 2, for example, a driving motor is adopted, in a preferred embodiment, the screw assembly is a twin-screw structure, the driving motor is connected to a gearbox, the gearbox is connected to the twin screws, thereby driving the twin screws to rotate, the thread grooves of the two screws are engaged with each other, and when the twin screws rotate, an efficient mixing environment for the enzymatic hydrolysis reaction is provided for the solid material and the liquid material, and the movement speed of the solid material and the liquid material in the sleeve is increased, so that the enzyme and the solid material are evenly mixed in a short time, and the twin screws can adopt the co-rotating twin screws, the inward counter-rotating twin screws, the outward counter-rotating twin screws, etc. commonly used by technicians in this field, and can be selected according to needs, which is not shown in the drawings.

[0028] One end of the sleeve 1 is connected to a solid feeder 3 that conveys solid materials into the sleeve in a closed manner. In one embodiment, the solid feeder 3 includes a first tank body 31 and a screw feeding mechanism 32. The screw feeding mechanism 32 includes a feeding motor and a screw feeding rod. The screw feeding rod is arranged in a solid feeding pipe (this is the basic structure of the screw feeder and will not be described in detail here). The upper part of one end of the screw feeding mechanism is connected to the discharge port of the first tank body. The second valve is arranged in the solid feeding pipe 8 behind the end of the screw feeding rod. The solid feeding pipe is connected to the sleeve 1. The screw feeding mechanism conveys solid materials into the sleeve 1. During the screw feeding process of the screw feeding rod, the solid materials fill the space between the screw feeding rod and the solid feeding pipe to ensure a closed feeding environment, thereby ensuring the pressure environment in the sleeve. In one embodiment, a solid feeder is disposed at the upper part of the sleeve, a solid feeder pipe is connected to the lower part of the solid feeder, an end of the solid feeder pipe away from the solid feeder is connected to the sleeve, a second valve is disposed on the solid feeder pipe, and a second booster is disposed at the upper part of the first tank body. Solid materials flow into the sleeve from top to bottom, and the solid materials fill the solid feeder pipe to ensure a closed feeding environment, thereby ensuring the pressure environment in the sleeve.

[0029] One end of the sleeve 1 is connected to a liquid feeder 4 for sealingly conveying liquid materials into the sleeve. In one embodiment, the liquid feeder 4 includes a second tank 42 and a liquid pump 41. One end of the liquid pump 41 is connected to the second tank 42, and the other end of the liquid pump 41 is connected to a liquid feeding pipe 9. A third valve is provided on the liquid feeding pipe, and the liquid feeding pipe is connected to the sleeve. The liquid fills the liquid feeding pipe to ensure a sealed feeding environment, thereby ensuring the pressure environment in the sleeve.

[0030] The end of the sleeve is provided with a discharge port, and the discharge port is provided with a first valve. When the first valve, the second valve, and the third valve are closed, the sleeve is a sealed environment, and the solid feeder 3 delivers the solid material to the sleeve in a closed manner, and the liquid feeder 4 delivers the liquid material to the sleeve in a closed manner. The space in the sleeve is occupied by the solid material and the liquid material, and the space is reduced, and the pressure in the sleeve increases, and the quantity of the material entering the sleeve is controlled to control the pressure value in the sleeve. Under a high pressure environment, due to the extrusion of the solid material and the liquid material by air, the contact effect of the enzyme with the solid small molecule is better, and under high pressure, the material flow rate is faster, and the enzyme and the solid material are contacted and reacted more quickly, so the enzymolysis reaction speed is faster. In addition, due to the shape and structural characteristics of the smaller width and the larger length of the extruder, the mixing of the solid material and the liquid material is more uniform under the high-speed rotation of the screw, the movement speed of the solid material and the liquid material is faster, and the contact of the enzyme with the unused solid material is more frequent, and the complete enzymolysis reaction of the solid material is achieved in a shorter time. The utility model realizes the enzymatic hydrolysis reaction of solid materials in the sleeve of the extruder under appropriate pressure, so that the enzymatic hydrolysis reaction speed is faster and the production efficiency is improved.

[0031] In one embodiment of the utility model, the first valve, the second valve and the third valve are all solenoid valves, and the switches of the first valve, the second valve and the third valve are controlled by a single chip microcomputer. In the initial state, the first valve is closed, and the second valve and the third valve are opened. After the solid feeder and the liquid feeder complete the feeding in sequence, the second valve and the third valve are closed, and a sealed high-pressure environment is formed in the sleeve. The twin screws rotate to drive the solid material and the liquid material to mix. In the high-pressure and high-speed mixing environment, the enzyme and the solid material undergo enzymolysis reaction. When the set reaction time is over, the first valve is opened or the first valve is opened again after pressure relief, and the enzymolyzed material is output from the sleeve. Then the first valve is closed, and the second valve and the third valve are opened, and this cycle is repeated.

[0032] The sleeve is connected to the first supercharger, and a pressure sensor is arranged in the sleeve. In production, it is necessary to balance the relationship between the solid materials and liquid materials transported into the sleeve and the pressure environment of the enzymolysis in the sleeve. The more solid materials and liquid materials there are, the greater the pressure in the sleeve. One is that the solid materials and liquid materials will produce a blocking force on the rotation of the screw, and the other is that the closed conveying pressure of the solid feeder and the liquid feeder increases. Another is that when the material delivery reaches a suitable amount, the pressure in the sleeve cannot be further increased to increase the enzymolysis reaction rate. The sleeve is connected to the first supercharger. After the solid materials and liquid materials are transported into the sleeve, the first supercharger is adjusted to rush air into the sleeve to increase the pressure in the sleeve, thereby increasing the enzymolysis reaction rate. In addition, the pressure in the sleeve is monitored by setting a pressure sensor. The first supercharger stops supercharging after the pressure is increased to a suitable pressure. A pressure relief solenoid valve 10 is arranged on the wall of the sleeve 1. A pressure relief solenoid valve is provided. When the pressure in the sleeve is high or needs to be adjusted, the pressure is relieved through the pressure relief solenoid valve; or after the enzymatic hydrolysis reaction is completed, when the material in the sleeve is output from the first valve, the pressure is first relieved through the pressure relief valve, and then the first valve is opened. The pressure sensor transmits the monitored pressure signal to the single-chip microcomputer, which controls the on / off of the first supercharger and the switch of the electromagnetic pressure relief valve.

[0033] A heating clamp is fixed outside the sleeve and a power supply is set to power the heating clamp. A temperature sensor is set inside the sleeve. When the temperature reaches the optimal reaction temperature, heating is stopped or the heating power is reduced. The heating switch and heating power of the heating clamp are also controlled by the single chip microcomputer.
