As shown in fig. 1, a vegetable protein beverage pulping system according to an embodiment of the present utility model includes a batch hopper 1, a first conveyor 2, a soaking tank 3, a second conveyor 4, a first refiner 5, a first buffer tank 7, a first pump 8, a first slurry separator 9, a first water supply pipe, and a control and display system.

Wherein, the batching hopper 1 is provided with a feed inlet and a discharge outlet, and the batching hopper 1 is used for collocating the pulping raw materials. The raw materials are proportionally put into a proportioning hopper 1 through manual or mechanical equipment to form evenly mixed pulping raw materials.

The soaking cylinder 3 is provided with at least one. The soaking cylinder 3 is provided with a feed inlet and a discharge outlet, and the soaking cylinder 3 is used for soaking the pulping raw materials. A stirring mechanism can be arranged in the soaking cylinder 3 so as to further uniformly mix and thoroughly soak the pulping raw materials. The first water supply pipeline is communicated with the soaking cylinders 3, each soaking cylinder 3 is provided with a water outlet corresponding to each first water supply pipeline, and each water outlet is provided with a valve actuator independently. And, the discharge port of each soaking cylinder 3 is independently provided with a valve actuator. As shown in fig. 1, the first water supply pipe mainly refers to a tap water pipe RW.

Since a certain time is required for the soaking of the refining raw material, the subsequent refiner is prevented from being stopped in order to reduce waiting, when the soaking cylinders 3 are provided with more than two, for example four as shown in fig. 1, the soaking cylinders 3 are arranged side by side with each other. The advantage of this arrangement is that a plurality of soaking cylinders 3 can be used for alternately soaking and discharging materials, so that the soaked pulp grinding raw materials are always conveyed to the subsequent pulp grinding machine, and the pulp making efficiency is improved.

The first conveyor 2 is arranged between the discharge port of the proportioning hopper 1 and the feed port of the soaking cylinder 3. The first conveyor 2 is provided with a discharge hole corresponding to each soaking cylinder 3, and a valve with a valve actuator is independently arranged at each discharge hole. The first conveyor 2 is configured to convey the raw material for refining disposed in the batch hopper 1 into the dipping cylinder 3. Because the raw materials are mainly particles such as soybean, mung bean, in order to guarantee conveying effect, the first conveyor 2 can be selected as a tube chain type conveyor, the tube chain type conveyor is provided with a closed pipeline, a transmission chain piece is arranged in the closed pipeline, and the chain piece is used as a transmission component to drive the materials to move along the pipeline. When the horizontal conveying is carried out, the material particles are subjected to the thrust of the chain sheet in the moving direction, and when the internal friction force between the material layers is larger than the external friction force between the material and the pipe wall, the material moves forwards along with the chain sheet to form a stable material flow; when the vertical conveying is carried out, the material particles in the pipe are pushed upwards by the chain sheet, and because the lower part feeding prevents the upper part material from sliding downwards, lateral side pressure is generated, so that the internal friction force of the materials is enhanced, and when the internal friction force between the materials is larger than the external friction force between the materials and the inner wall of the pipe and the self weight of the materials, the materials are conveyed upwards along with the chain sheet, so that a continuous material flow is formed. The pipe chain conveyor has compact structure and small occupied space, and can change the conveying direction in three dimensions; the materials are smoothly conveyed along the pipe, so that the materials are less damaged, and the slow curved conveying ensures that few material particles generate scraps; the system is not blocked, and the device is suitable for conveying materials in various forms. In an embodiment of the utility model, a GL80 tube chain conveyor manufactured by Weisco epitaxial mechanical equipment Inc. may be used to meet the conveying requirements.

The first conveyor 2 has a remarkable effect of lifting the pulp grinding raw material in the proportioning hopper 1 to a certain height, so that even if the discharge hole of the proportioning hopper 1 is lower than the feed hole of the soaking cylinder 3, the pulp grinding raw material can smoothly enter the soaking cylinder 3 by means of gravity.

The second conveyor 4 is disposed between the discharge port of the soaking cylinder 3 and the feed port of the first pulping machine 5, and the second conveyor 4 is configured to convey the pulping raw material soaked in the soaking cylinder 3 to the first pulping machine 5. The second conveyor 4 can be considered as a screw conveyor, and the screw conveyor is a machine which drives a screw to rotate by a motor and pushes materials to achieve the conveying purpose, can horizontally, obliquely or vertically convey, and has the advantages of simple structure, small cross-sectional area, good sealing performance, convenience in operation, easiness in maintenance, convenience in sealing and transportation and the like. In the embodiment of the utility model, a ss521 type screw conveyor manufactured by Sanshi environmental protection equipment limited company in Poisson can be used to meet the conveying requirement.

Since the height of the stock can be raised by the first conveyor 2 before, if the discharge opening of the soaking cylinder 3 is higher than the feed opening of the first refiner 5, the first conveyor 2 can be replaced by a pipe, and the refined stock can be directly led from the soaking cylinder 3 into the first refiner 5 by gravity.

The first refiner 5 is used for grinding the soaked refiner stock into refiner pulp. In the embodiment of the utility model, the first pulping machine 5 can be a JM-180 colloid mill produced by the Dacron chemical mechanical plant of Lystate, so as to meet the pulping requirement.

The feed inlet of the first buffer tank 7 is communicated with the discharge outlet of the first pulping machine 5 through a pipeline, and the feed inlet of the first buffer tank 7 is lower than the discharge outlet of the first pulping machine 5, so that the pulping produced by the first pulping machine 5 can directly enter the first buffer tank 7 through the action of gravity. The first buffer tank 7 is used for temporarily collecting the refining for concentrated feeding to subsequent equipment. The valve with the valve actuator is also arranged at the discharge port of the first buffer tank 7, the discharge port of the first buffer tank 7 is additionally provided with an emptying port, and the emptying port is additionally provided with the valve actuator.

The first pump 8 is communicated with the discharge port of the first buffer tank 7 and the feed port of the first slurry separator 9 through pipelines, and the first pump 8 is used for pumping the ground slurry into the first slurry separator 9.

The first slurry separator 9 is used for separating the ground slurry and separating slurry and slag, thereby completing the entire pulping process. The slurry is the semi-finished product of the vegetable protein beverage, and can be sold after the following procedures of blending, packaging and the like. In the embodiment of the utility model, the first slag-pulp separator 9 can be an LW350 horizontal spiral discharge decanter centrifuge manufactured by Zhang Jiangxin middle and large centrifuge Limited company so as to meet the use requirement.

In the embodiment of the present utility model, the first conveyor 2, the second conveyor 4, the first refiner 5, the first pump 8, the first slurry separator 9 and the valve actuators of all valves are electrically connected to the control and display system, and for clarity of the drawing, the control and display system and the connection manner of the control and display system to each device are not illustrated in the drawing, but the connection manner of the control and display system to each device is easily known and can be implemented by those skilled in the art. The running state/opening and closing state of each device can be displayed on the control and display system so as to intuitively know the related running/parameter data, and the actions/opening and closing of each device can be uniformly implemented by the control and display system. The control and display system can be made of a storable medium capable of writing and running a program, such as a PLC board or a direct use computer. It should be noted that the control and display system should be provided with a display to display relevant operation/opening/closing information of each device.

In the embodiment of the utility model, after raw materials are put into a proportioning hopper 1, the raw materials are conveyed into a soaking cylinder 3 by a first conveyor 2 for soaking, the soaked pulp-grinding raw materials are conveyed into a first pulp grinder 5 by a second conveyor 4 or a pipeline, the pulp-grinding raw materials are guided into a first buffer tank 7 for temporary storage by the first pulp grinder 5 after being ground by the first pulp grinder, and then the pulp-grinding pump in the first buffer tank 7 is used for pumping the pulp into a first pulp separator 9 to separate pulp and slag by a first pump 8, so that the whole pulp-making process is completed. The whole process does not need too much manual participation, each process can automatically and continuously run after corresponding parameters are set, and the production efficiency is improved while the labor force is liberated. Meanwhile, the whole system adopts pipelines for conveying at multiple positions, so that closed conveying can be realized, overflow is reduced, the working environment is improved, and the environment is kept clean.

After the system has completed pulping, the system needs to be cleaned. In the past, each equipment node is manually cleaned independently, so that the efficiency is very low, and the cleaning is possibly not clean or thorough. In the embodiment of the utility model, the device further comprises a cleaning liquid pipeline which is respectively communicated with the soaking cylinder 3, the first pulping machine 5, the first buffer tank 7 and the first pulp separator 9. And valves with valve actuators are arranged at the water outlet of the cleaning liquid pipeline, and the valve actuators of the valves are electrically connected with the control and display system. As shown in fig. 1, the cleaning liquid pipeline mainly refers to a cleaning in place pipeline CIP (Clean In Place), and CIP cleaning is not only applied to production equipment, but also is applied to a safe and automatic cleaning system with a simple operation method, and is introduced into almost all factories such as food, beverage and pharmacy. CIP cleaning not only cleans the machine, but also controls microorganisms. After pulping is finished, the control and display system controls valves of cleaning liquid pipelines at corresponding equipment to be opened, all the equipment runs idle, only cleaning liquid flows in the whole system, and cleaning balls can be arranged at water outlets of the cleaning liquid pipelines to enhance cleaning effect. The cleaning operation does not need too much labor, and is efficient and clean.

In order to make the refining finer, an embodiment of the utility model may also comprise a second refiner 6. The feed inlet of the second pulping machine 6 is communicated with the discharge outlet of the first pulping machine 5 through a pipeline, and the feed inlet of the second pulping machine 6 is lower than the discharge outlet of the first pulping machine 5, so that pulping is automatically led into the second pulping machine 6 from the discharge outlet of the first pulping machine 5 through gravity. The discharge port of the second pulping machine 6 is communicated with the feed port of the first buffer tank 7 through a pipeline, and the feed port of the first buffer tank 7 is lower than the discharge port of the second pulping machine 6. The second refiner 6 is electrically connected to the control and display system. In the pulping process, the first pulping machine 5 can be used as a coarse grinding machine, and the second pulping machine 6 can be used as a fine grinding machine, so that full pulping is ensured, the pulping is fine and uniform, and the quality of final pulp is ensured. The second refiner 6 may be the same equipment as the first refiner 5 or similar equipment of a higher grade of refining fineness than the first refiner 5.

The first slurry separator 9 is capable of separating the refined slurry and obtaining slurry and slag, which is typically collected for further use. However, in practice, the slag also contains a large amount of protein that is not dissolved in the slurry, and thus, the embodiment of the present utility model also contemplates a process of performing secondary treatment on the slag, based on detection and analysis. For example, the present utility model may further include a slag washer 10, a second pump 11, a second slag separator 12, and a second water supply pipe. The feed inlet of the slag washing machine 10 is communicated with the slag outlet of the first slag-pulp separator 9 through a pipeline, and the feed inlet of the slag washing machine 10 is lower than the slag outlet of the first slag-pulp separator 9, so that slag can be automatically guided into the first slag-pulp separator 9 through gravity. The second pump 11 is communicated with a discharge port of the slag washer 10 and a feed port of the second slag-pulp separator 12 through pipelines. The second water supply pipeline is communicated with the slag washer 10, and a valve with a valve actuator is arranged at the water outlet of the second water supply pipeline. The valve actuator of the valve at the water outlet of the second water supply pipeline, the slag washer 10 and the second pump 11 are electrically connected with the control and display system. The second slurry separator 12 may be the same equipment as the first slurry separator 9. To ensure the slag washing effect of the slag washing machine 10, water needs to be added and sufficiently stirred through the second water supply pipeline in the slag washing process, so that proteins in the slag can be dissolved into the water as much as possible. As shown in FIG. 1, the second water supply line is mainly a hot water line WW, and in practice it has been found that although the addition of normal temperature water also dissolves proteins in the slag into water, the protein dissolution is more easily promoted if the water is heated, particularly hot water having a temperature of 50 ℃ or higher and 95 ℃ or lower. After washing the slag, the slag slurry obtained by mixing the slag and water is pumped to a second slag-slurry separator 12 by a second pump 11 to perform slag-slurry separation again, so that the slurry containing protein in the slag slurry can be separated. The utilization rate of the pulping raw material is improved by adding secondary slag-pulp separation into washing slag, so that the production cost is reduced, and the method is more energy-saving and environment-friendly. In the embodiment of the utility model, the slag washer 10 can be a Q1 type washer manufactured by Shandong Pont machine manufacturing Co., ltd.

Based on this finding, the second water supply line in the embodiment of the utility model may also be in communication with the infusion cylinder 3 and the first refiner 5, respectively. And valves with valve actuators are respectively arranged at the water outlets of the second water supply pipeline corresponding to the soaking cylinder 3 and the first pulping machine 5, and the valve actuators of the valves are electrically connected with the control and display system. For the same reason, soaking the refining raw material in hot water can make the protein more easily dissolved into the slurry during subsequent refining than soaking the refining raw material in water at normal temperature. If the first refiner 5 requires the addition of water during refining, the addition of water will cause more protein to dissolve into the slurry than if the water is at ambient temperature.

The embodiment of the utility model further comprises a second buffer tank 13 and a third pump 14. The feed inlet of the second buffer tank 13 is simultaneously communicated with the slurry outlet of the first slurry separator 9 and the slurry outlet of the second slurry separator 12 through pipelines, and the feed inlet of the second buffer tank 13 is simultaneously lower than the slurry outlet of the first slurry separator 9 and the slurry outlet of the second slurry separator 12 so as to realize gravity self-flow. The third pump 14 is communicated with a discharge port of the second buffer tank 13 through a pipeline. A valve with a valve actuator is arranged at the discharge port of the second buffer tank 13. And a valve actuator of a valve at the discharge port of the second buffer tank 13 and the third pump 14 are electrically connected with the control and display system. The slurry obtained by the two slurry-slag separation is led into a second buffer tank 13 for storage, and after the quantity of the slurry stored is enough, the slurry can be pumped to a tank truck or directly pumped to a blending station through a third pump 14 for subsequent processing.

Obviously, the second buffer tank 13 also needs to be cleaned. Therefore, the cleaning liquid pipe in the embodiment of the present utility model is also communicated with the second buffer tank 13. And a valve with a valve actuator is arranged at the position of the cleaning liquid pipeline corresponding to the water outlet of the second buffer tank 13, and the valve actuator of the valve is electrically connected with the control and display system.

In addition, in practice we have found that the refining speed of the first refiner 5/second refiner 6 does not necessarily exactly match the separating speed of the first separator 9/second separator 12, e.g. the separating speed may be greater than the refining speed, resulting in the first separator 9/second separator 12 idling and white-space consuming energy. Therefore, the embodiment of the utility model also considers that a high liquid level detector and a low liquid level detector are additionally arranged in the first buffer tank 7, and the high liquid level detector and the low liquid level detector are electrically connected with the control and display system. The first refiner 5/second refiner 6 may then be operated for a period of time before storing a certain amount of refiner pulp in the first buffer tank 7 and taking into account the start-up of the subsequent equipment. For example, when the high level detector triggers, a feedback signal is sent to the control and display system, which then controls the first pump 8 to increase pumping power; when the low level detector triggers, a signal is fed back to the control and display system, which then controls the first pump 8 to reduce the pumping power. Thus, the first and second slurry separators 9 and 12 can be ensured to always operate normally without idling. In the embodiment of the utility model, the high liquid level detector and the low liquid level detector can be selected as LX-30 tuning fork material level switches manufactured by Chengdu Fei technology Limited liability company so as to meet detection requirements. When the tuning fork touches liquid or other materials, the inherent vibration frequency is reduced, energy is consumed on friction among the material particles, the vibration amplitude is forced to be attenuated sharply to stop vibrating, the liquid level switch is activated by the change of the frequency, and an on-off signal is generated.

The following describes the entire pulping process of the system with a specific example: for example, it is desirable to prepare a slurry comprising soybeans and mung beans. Firstly, 100kg of soybeans and 50kg of mung beans are poured into a proportioning hopper 1, and a first conveyor 2 is started to convey the soybeans and the mung beans to a high place and fall into a soaking cylinder 3. Tap water is introduced into the soaking tank 3 through a first water supply pipeline or hot water at 50-95 ℃ is introduced into the soaking tank 3 through a second water supply pipeline, and after soybeans and mung beans are soaked for one hour, the stirring mechanism can be started, and a valve at a discharge hole at the bottom of the soaking tank 3 is opened. Simultaneously, tap water or hot water is continuously added into the soaking tank 3, and soybeans, mung beans and water enter the first pulping machine 5 through the second conveyor 4 or a pipeline and are ground to a particle size of less than 0.2mm, so that a slurry is formed. The slurry falls into the second refiner 6 through a pipe, is ground to a particle size of 30 μm or less, and flows into the first buffer tank 7 through a pipe. When the low liquid level detector in the first buffer tank 7 is triggered, the first pump 8, the first slurry separator 9, the slag washer 10, the second pump 11 and the second slurry separator 12 are turned on, and then slurry is pumped to the first slurry separator 9 by the first pump 8. The slurry separated by the first slurry separator 9 directly enters the second buffer tank 13 through a pipeline, the slag enters the slag washer 10 and is added with hot water to be stirred into slag slurry, then the slag slurry is pumped to the second slurry separator 12 by the second pump 11 to be separated again, the obtained slurry directly enters the second buffer tank 13 through the pipeline, and the slag separated by the second slurry separator 12 is collected. The slurry in the second buffer tank 13 may then be pumped to a blending station or tank car by a third pump 14 as required. After pulping is completed, the whole system idles, then each water outlet of a cleaning liquid pipeline is opened, the cleaning liquid fully cleans each device through the cleaning ball, and the cleaning wastewater is collected or treated and then discharged. The operation/switching of each device can be uniformly completed at the control and display system, and the operation information of each device and the opening and closing information of each valve can be uniformly displayed at the control and display system.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

It will be apparent to those skilled in the art that various modifications and adaptations can be made without departing from the spirit and scope of the utility model, and such modifications and adaptations are intended to be comprehended within the scope of the utility model.
