[0002] In numerous fields such as food, pharmaceuticals, and biochemicals, prolysins have wide-ranging applications due to their unique physicochemical properties and biological activities. For example, in the food industry, they can serve as high-quality food additives to improve the texture, taste, and stability of food; in the pharmaceutical field, certain properties of prolysins demonstrate their potential in the development of drug carriers. However, obtaining high-quality prolysins remains one of the challenges facing the industry.

[0003] Traditionally, the sources of prolamins have been limited and costly to extract, making it difficult to meet the growing market demand. Distillers' grains, a major byproduct of the brewing industry, are produced in enormous quantities. Statistics show that the brewing industry generates millions of tons of distillers' grains annually. These grains actually contain abundant prolamins, but for a long time, due to a lack of efficient extraction technology, most of the grains have either been simply discarded or used only as low-value animal feed, resulting in a huge waste of resources.

[0004] Early attempts to extract prolamins from distiller's grains were mostly manual or semi-automated processes, which had many drawbacks. First, the extraction efficiency was low; the large amount of manpower required not only increased production costs but also made it difficult to guarantee consistent product quality. Second, the separation process was not precise enough, resulting in low purity prolamins containing many impurities, which seriously affected their application in high-end fields. Moreover, traditional methods often lacked effective recycling mechanisms when dealing with impurities such as rice husks in distiller's grains, increasing subsequent processing costs and putting significant pressure on the environment.

[0005] With increasing environmental awareness and the growing popularity of the concept of sustainable development, it is urgent to develop a technology that can efficiently, environmentally friendly and low-cost extract prolysins from distiller's grains. Utility Model Content

[0013] The stirring device is used for stirring the distiller's grain powder in the alcohol solution, so that the prolamine in the distiller's grains is dissolved in the alcohol solution, and the alcohol solution containing the prolamine is output to the pre-storage tank, and the waste material insoluble in the alcohol solution is output to the second conveying belt.

[0014] The second conveying belt is used for transporting the bran and the waste material insoluble in the alcohol solution to the combustion pool.

[0023] In terms of cost control, on the one hand, the efficient extraction process reduces the labor input and lowers the labor cost; on the other hand, the full utilization of the vinasse resources converts the originally low-value or discarded vinasse into high-value prolamine, turning waste into treasure, realizing the value-added of resources, and lowering the production cost as a whole.

[0024] The environmental benefits are also outstanding. By recycling and reusing the impurities such as chaff in the vinasse and the waste generated in the extraction process, and conveying them to the combustion pool, the pollution of waste to the environment is reduced. At the same time, the recycling of the alcohol solution reduces the consumption and emission of chemical reagents, in line with the concept of sustainable development.

[0029] Please see Figure 1 This invention provides an automated device for extracting prolysin from distiller's grains, comprising:

[0030] Distillery lees tank, used to receive lees containing chaff;

[0031] Combustion tank, used to heat the lees tank to obtain dried lees containing chaff;

[0032] The first conveyor belt is used to receive dried distiller's grains containing chaff and transport them to the screening device;

[0033] The screening device is used to screen and separate the chaff from the dry distillers' grains containing chaff, and output the chaff to the second conveyor belt and the distillers' grains to the storage bin.

[0034] Storage bins are used to store the lees that have been filtered out by the screening device;

[0035] The pulverizer is used to receive the lees stored in the storage silo, pulverize them into powder to obtain lees powder, and output the lees powder to the stirring device;

[0036] The stirring device is used to stir the lees powder in the alcohol solution, so that the alcohol-soluble protein in the lees dissolves in the alcohol solution, and outputs the alcohol solution containing the alcohol-soluble protein to the pre-storage tank, and outputs the waste material that does not dissolve in the alcohol solution to the second conveyor belt.

[0037] The second conveyor belt is used to transport rice husks and waste materials that are insoluble in alcohol solution to the combustion pool;

[0038] Pre-storage tanks are used to store alcohol solutions containing alcohol-soluble proteins;

[0039] A dryer is used to receive an alcohol solution containing alcohol-soluble proteins and dry it to obtain alcohol vapor and alcohol-soluble proteins;

[0040] Finished product storage tank, used to store alcohol-soluble protein obtained from the dryer;

[0041] A condenser is used to condense the alcohol vapor obtained from the dryer to obtain liquid alcohol.

[0042] An alcohol return tank is used to receive and store liquid alcohol condensed by a condenser.

[0043] The storage tank is used to receive the alcohol liquid from the alcohol return tank, adjust the concentration and volume of the alcohol solution, and then output it to the stirring device.

[0044] In this embodiment, the distiller's grains tank can be a custom-designed concrete structure, constructed according to the actual site conditions, with appropriate structural design and waterproofing. In this embodiment, the combustion tank can be a high-efficiency natural gas-heated combustion tank. A belt conveyor can be used in this embodiment.

[0045] This automated device is designed for the efficient extraction of prolamins from distiller's grains. The process begins with the distiller's grains tank receiving grains containing rice husks. This dried distiller's grains are then heated in a combustion tank and conveyed by a first conveyor belt to a screening device. The screening device separates the rice husks from the distiller's grains; the rice husks are conveyed by a second conveyor belt to the combustion tank, while the distiller's grains are stored in a storage bin. The distiller's grains in the storage bin are pulverized into powder by a pulverizer and conveyed to a stirring device. There, they are stirred in an alcohol solution, causing the prolamins to dissolve. Insoluble waste is also conveyed by a second conveyor belt to the combustion tank. The alcohol solution containing the prolamins is stored in a pre-storage tank and then enters a dryer to separate the alcohol vapor from the prolamins. The prolamins are then stored in a finished product storage tank. The alcohol vapor is condensed into liquid alcohol and stored in an alcohol reflux tank. The alcohol solution concentration and volume are then adjusted in the storage tank before being returned to the stirring device for recycling. The device works in close coordination among all its components, achieving a fully automated process from receiving and processing the lees, extracting prolysin, to recycling alcohol. This improves the efficiency of prolysin extraction and enables the rational recycling of waste and alcohol, reducing costs and environmental pollution, thus demonstrating significant economic and environmental benefits.

[0046] Preferably, the screening device includes an electric sieve and a blower; the electric sieve is positioned above the second conveyor belt; the electric sieve is used to receive dried distiller's grains containing chaff from the first conveyor belt and to electrically screen them; a chaff channel is provided between the electric sieve and the second conveyor belt; the storage bin is positioned below the electric sieve; a pipe connects the output end of the electric sieve and the input end of the storage bin; the blower is used to blow chaff into the chaff channel during the screening process of the dried distiller's grains containing chaff by the electric sieve, and under the influence of gravity, the chaff is output along the chaff channel to the second conveyor belt, and the distiller's grains are output to the storage bin along the pipe between the electric sieve and the storage bin.

[0047] In this embodiment, the electric screen can be a YK series circular vibrating screen, such as the 2YK1545 model. This electric screen has a screen area of ​​6.75㎡ and can efficiently process large quantities of dried distiller's grains containing chaff. Driven by a motor, it generates excitation force with an eccentric block, causing the screen to vibrate at a suitable frequency and amplitude. When the dried distiller's grains containing chaff, delivered from the first conveyor belt, enter the screen, the grains and chaff continuously tumble and bounce under the vibration. Large particles of chaff and some impurities are initially separated. Due to the vibration of the screen and the material's own bouncing, these chaff particles gradually move towards the edge of the screen. A DF-500 centrifugal blower is used. This blower can flexibly adjust the wind speed via a frequency converter, allowing for precise speed control during the screening of dried distiller's grains. When the electric screen is running, the strong airflow from the blower acts evenly on the material on the screen. Because the density of chaff is relatively low, the lighter chaff is more easily blown up and moved with the wind direction under the action of the wind. The rice husks are precisely blown into the rice husk channel located between the electric sieve and the second conveyor belt. The rice husk channel is designed as a smooth, inclined pipe with a precisely calculated angle, such as 30°, to ensure that the rice husks slide smoothly down the channel to the second conveyor belt under the combined effects of gravity and airflow. During the screening of this batch of distiller's grains, approximately 5 cubic meters of rice husks are quickly and stably output to the second conveyor belt through the rice husk channel, achieving initial separation of the rice husks from the distiller's grains. The electric sieve is connected to the storage bin via a pipe with a diameter of 0.8 meters. After being finely screened by the multiple layers of mesh on the electric sieve, the distiller's grains fall into the storage bin under gravity along the pipe.

[0048] In this embodiment, the screening device, consisting of an electric sieve and a blower, significantly improves screening efficiency compared to traditional screening methods, saving considerable time compared to manual or simple mechanical screening. Simultaneously, it offers higher screening precision. By rationally adjusting the vibration parameters of the electric sieve and the wind speed of the blower, it can more accurately separate rice bran and distiller's grains, resulting in a substantial reduction in rice bran content in the distiller's grains entering the storage silo, thus improving the quality of the subsequently extracted prolysin product. Furthermore, the entire screening process is automated, reducing manual intervention, lowering labor costs, and enhancing production stability and reliability.

[0049] Preferably, the pulverizer is located below the storage bin; the pulverizer is located above the stirring device; the input end of the pulverizer and the output end of the storage bin are connected by a pipe, wherein the connection state of the pipe is controlled by a first valve; the output end of the pulverizer and the stirring device are connected by a pipe.

[0050] In this embodiment, the grinder is installed directly below the storage silo and above the mixing device. The output end of the storage silo is connected to the input end of the grinder via a 0.5-meter diameter stainless steel pipe. An electrically controlled first valve is installed on the pipe. When a preset volume of screened distiller's grains accumulates in the storage silo, the operator in the control room issues a command to open the first valve. Under gravity, the distiller's grains quickly fall into the grinder through the pipe. The output end of the grinder is connected to the mixing device via a flexible pipe. After the grinder grinds the distiller's grains into a uniform powder, it falls into the mixing device through the pipe under gravity.

[0051] In this embodiment, gravity is used for transporting the distiller's grains, reducing additional power consumption and lowering energy costs. Directly connecting the pulverizer to the mixing device avoids dust and loss during the transfer of powdered distiller's grains, ensuring material integrity and improving the utilization rate of raw materials for prolyl protein extraction. Furthermore, the entire process is automated through pipeline connections and valve control, reducing manual intervention and labor costs, while simultaneously improving the stability and reliability of the production process, ensuring efficient and continuous operation from distiller's grains storage to pulverization and then to prolyl protein extraction.

[0052] Preferably, the stirring device is positioned above the second conveyor belt, and a pipe is provided between the stirring device and the second conveyor belt, wherein the connection state of the pipe is controlled by a fifth valve.

[0053] In this embodiment, the stirring device is positioned directly above the second conveyor belt. A 0.4-meter diameter pipe connects the bottom of the stirring device to the second conveyor belt, and this pipe is equipped with a fifth valve, precisely controlled by an automated control system. After the stirring device completes the stirring process of mixing the distiller's grains powder and the alcohol solution, the internal mixture undergoes a thorough reaction. The alcohol-soluble protein dissolves in the alcohol solution, while simultaneously producing waste material insoluble in the alcohol solution. The automated control system issues a command to open the fifth valve. Under gravity, the insoluble waste material quickly flows through the pipe and onto the second conveyor belt below. This layout and connection method brings many significant benefits. On the one hand, it enables rapid and automatic transfer of waste material, eliminating the need for manual cleaning, greatly saving labor costs, and avoiding the pollution risks that manual operation may bring, thus ensuring a hygienic production environment. On the other hand, the precise control of the pipe and valve ensures the controllability of the waste material transportation process, improving the stability and reliability of the production process. Moreover, the waste material can be discharged from the stirring device in a timely manner, freeing up space for the next stirring process, accelerating the entire alcohol-soluble protein extraction production rhythm, and significantly improving production efficiency.

[0054] Preferably, the storage tank is positioned above the stirring device; the alcohol reflux tank is positioned above the storage tank; the storage tank and the stirring device are connected by a pipe, wherein the connection state of the pipe is controlled by a second valve; the storage tank and the alcohol reflux tank are connected by a pipe, wherein the connection state of the pipe is controlled by a fourth valve; the condensing device is positioned above the alcohol reflux tank, and the condensing device is connected to the alcohol reflux tank by a pipe.

[0055] In this embodiment, the storage tank is installed directly above the stirring device and has precise liquid level and concentration monitoring functions, such as a liquid level detection device and a concentration detection device in the storage tank. The storage tank is connected to the stirring device via a 0.3-meter diameter pipe, and the second valve on the pipe is precisely controlled by an automated system according to the concentration and level requirements of the alcohol solution in the stirring device. The storage tank and the alcohol return tank are connected via a 0.25-meter diameter pipe, and the fourth valve is also controlled by the automated system to ensure that the alcohol liquid flows between the two as needed. A tubular condenser, such as the LN-20 type, is installed above the alcohol return tank and is tightly connected to the alcohol return tank via a pipe. When the condenser starts working, it condenses the alcohol vapor generated by the dryer, and this alcohol liquid flows into the alcohol return tank below through the pipe. When the automated system detects that the concentration or level of the alcohol solution in the storage tank needs adjustment, it automatically opens the fourth valve. Under the action of gravity, the alcohol liquid flows into the storage tank until the alcohol solution in the storage tank reaches the appropriate concentration and level. At this time, the fourth valve closes. When the stirring device needs to be replenished with alcohol solution, the automated system opens the second valve based on real-time monitoring data within the device. The alcohol solution, adjusted for concentration and volume in the storage tank, flows into the stirring device through a pipe at a suitable flow rate. Taking a single alcohol solution replenishment operation as an example, within 5 minutes, 2 cubic meters of the required alcohol solution flows into the stirring device, meeting its alcohol solution needs and ensuring the smooth progress of the alcohol-soluble protein extraction process.

[0056] This equipment layout and connection method has yielded significant results. First, utilizing gravity for the transport of liquid alcohol reduces the investment in additional power equipment and energy consumption, thereby lowering production costs. Second, automated valve control ensures precise and efficient mixing and delivery of the alcohol solution, guaranteeing that the stirring device always obtains the required alcohol solution, thus improving the stability and product quality of alcohol-soluble protein extraction. Furthermore, the compact layout and smooth connections between the equipment accelerate alcohol recycling, improve the efficiency of the entire production process, and achieve a highly efficient connection from alcohol vapor condensation to recycling, promoting the optimization of the alcohol-soluble protein extraction process.

[0057] Preferably, the pre-storage tank is located below the stirring device, and the pre-storage tank is connected to the stirring device via a pipe, wherein the connection status of the pipe is controlled by a third valve.

[0058] In this embodiment, the pre-storage tank is strategically positioned below the stirring device. The pre-storage tank and the stirring device are connected via a 0.35-meter diameter pipe, and a third valve installed on the pipe is precisely controlled by an automated control system. Once the stirring device completes the mixing process of the distiller's grains powder and the alcohol solution, ensuring the alcohol-soluble proteins in the distiller's grains are fully dissolved in the alcohol solution, the automated system opens the third valve according to a preset program and parameters such as the liquid level in the stirring device. Under gravity, the alcohol solution containing the alcohol-soluble proteins quickly flows through the pipe into the pre-storage tank below. This layout and connection method brings many positive effects. On the one hand, utilizing gravity for solution transport avoids the need for additional pumping equipment, reducing equipment costs and energy consumption, lowering the risk of production interruptions due to equipment failure, and improving the reliability of the production process. On the other hand, the automated control of the third valve allows for precise control of the solution transfer timing and flow rate, ensuring the stirring device is emptied in a timely manner, preparing for the next mixing cycle, and significantly improving production efficiency. Meanwhile, the pre-storage tank centrally stores the alcohol solution containing prolysin, providing a stable supply of raw materials for the subsequent drying process, ensuring the continuity and stability of the entire prolysin extraction process, and helping to improve the quality and yield of the final product.

[0059] Preferably, the pre-storage tank is located below the dryer, and the pre-storage tank is connected to the dryer via a pipe, wherein a pump is installed on the pipe.

[0060] In this embodiment, the pre-storage tank is installed below the dryer. The pre-storage tank and the dryer above are tightly connected by a 0.4-meter diameter pipe. A centrifugal transfer pump is installed on the pipe, with a head sufficient to stably transport the solution from the pre-storage tank to the dryer. After the stirring device completes the stirring process of the distiller's grains powder and alcohol solution, ensuring the alcohol-soluble protein is fully dissolved in the alcohol solution, this solution first flows into the pre-storage tank for temporary storage. The operator starts the transfer pump on the pipe according to the dryer's operating status and production plan. Under the pump's action, the solution is smoothly transported through the pipe to the dryer for drying. This layout and connection method brings a series of significant benefits. From an equipment operation perspective, precise pump control allows for flexible adjustment of the solution delivery rate according to the dryer's processing capacity, avoiding the impact of excessive or insufficient solution supply on the drying effect and ensuring efficient and stable operation of the drying process. From a production process perspective, the pre-storage tank, as a buffer storage link, effectively coordinates the production rhythm between the stirring device and the dryer. Even if the output time of the stirring device and the processing time of the dryer are not perfectly matched, they can be adjusted through the pre-storage tank to ensure the continuity of the entire alcohol-soluble protein extraction process.

[0061] Preferably, the dryer is located below the condenser, and the finished product storage tank is located below the dryer; the dryer is connected to the condenser and the finished product storage tank respectively via pipes.

[0062] In this embodiment, the dryer is strategically positioned below the condenser, with the finished product storage tank located directly below the dryer. The condenser is connected to the dryer via a 0.3-meter diameter pipe. When the dryer dries the alcohol solution containing prolysin, the alcohol vaporizes into vapor. This alcohol vapor rises and enters the condenser. The condenser employs a tubular condenser design; the vapor is rapidly cooled within the tubular structure, condensing into liquid alcohol, which then flows back through the pipe to the alcohol return tank below for recycling. The finished product storage tank is connected to the dryer via a 0.25-meter diameter pipe. After processing by the dryer, the alcohol vapor is separated, and the remaining high-purity prolysin falls directly into the finished product storage tank below under gravity. This layout and connection method brings many positive effects. From an operational perspective, the dryer's lower position utilizes gravity to transport the prolysin to the finished product storage tank, eliminating the need for additional transport equipment and reducing energy consumption and equipment maintenance costs. Simultaneously, the condenser's upper position facilitates the rising of alcohol vapor into the condenser, improving condensation efficiency. From a production process perspective, the close connection between the dryer, condenser, and finished product storage tanks makes the entire production process smoother. The seamless integration of alcohol-soluble protein extraction, drying, separation, and storage effectively avoids material loss and contamination risks in intermediate stages, ensuring the quality and yield of alcohol-soluble protein. Furthermore, through rational equipment selection and layout, efficient production operations are achieved, significantly improving the overall efficiency of the alcohol-soluble protein extraction process and bringing better economic benefits and market competitiveness to the enterprise.

[0063] How this utility model is used:

[0064] The lees containing rice husks are placed in a lees tank, which is then heated in a combustion tank to obtain dried lees containing rice husks. The dried lees containing rice husks are transported to a screening device via a first conveyor belt. An electric sieve in the screening device receives the dried lees containing rice husks from the first conveyor belt and performs electric screening. Simultaneously, a blower blows rice husks into a rice husk channel during screening. Under gravity, the rice husks are output along the rice husk channel to a second conveyor belt, while the lees are output through a pipe between the electric sieve and the storage bin for storage. The stored lees are then processed by a pulverizer located below the storage bin. The input end of the pulverizer and the output end of the storage bin are connected by a pipe controlled by a first valve. When needed, the first valve is opened, allowing the lees to enter the pulverizer and be pulverized into powder, resulting in lees powder. The lees powder is then output through a pipe to a stirring device located above the second conveyor belt. The stirring device stirs the lees powder in an alcohol solution, dissolving the alcohol-soluble proteins in the lees. An alcohol solution containing prolysin is output to a pre-storage tank via a pipeline (controlled by a third valve). Waste materials insoluble in the alcohol solution are output to the second conveyor belt via a pipeline connected to the stirring device and the second conveyor belt via a fifth valve. The second conveyor belt transports rice husks and waste materials insoluble in the alcohol solution to a combustion tank for processing. The pre-storage tank is located below the dryer, and the two are connected via a pipeline equipped with a pump. The alcohol solution containing prolysin in the pre-storage tank is pumped to the dryer, where it is dried to obtain alcohol vapor and prolysin. Since the finished product storage tank is located below the dryer, the prolysin obtained from the dryer is output to the finished product storage tank for storage. The alcohol vapor obtained from the dryer rises to a condenser located above it, where it is condensed to obtain liquid alcohol. The liquid alcohol flows through a pipeline into an alcohol return tank located below the condenser for storage. The alcohol reflux tank is located above the storage tank, and the two are connected by a pipe whose connection is controlled by a fourth valve. When the fourth valve is opened, the alcohol liquid in the alcohol reflux tank flows into the storage tank. After the storage tank adjusts the concentration and volume of the alcohol liquid, it is output to the stirring device through a pipe whose connection is controlled by a second valve for use in the next stirring and extraction.
