Utility model patent CN206699336U, "A Protein Powder Production Device for Pregnant Women," discloses a design with a waste collection bin, which can collect waste generated during protein powder production, preventing clogging of the dust collector and filter, and effectively ensuring the smooth operation of the equipment. However, existing technologies still suffer from low protein powder production efficiency and a large amount of protein clumps caused by high temperatures. Summary of the Invention

[0003] The purpose of this invention is to provide a protein powder production apparatus and method to solve the problems of low protein powder production efficiency and large amount of protein clumps caused by high temperature in the prior art.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A protein powder production apparatus includes a production component. The production component includes an inner production cylinder and a first jet pipe installed at the bottom of the inner sidewall of the inner production cylinder. A production cylinder bottom plate is fixedly sealed at the bottom of the inner production cylinder. Several first jet pipes are arranged in a circular array and located on the same horizontal plane. Each first jet pipe has its nozzle facing downwards. Simultaneous jetting from all the first jet pipes creates a downward spiral airflow, which can sweep away protein liquid and agglomerated protein powder located at lower positions on the production cylinder bottom plate, preventing agglomerated protein powder from adhering to the bottom plate after the production process. The production component also includes a second jet pipe, a third jet pipe, and a discharge oblique channel. A second jet pipe arranged in a circular array is positioned above the first jet pipe, and a third jet pipe arranged in a circular array is positioned above the second jet pipe. The inner sidewall of the inner production cylinder is connected and fixed to the second and third jet pipes respectively. The second jet pipe has its nozzle facing upwards. The pipes are located on the same horizontal plane, and the simultaneous ejection of gas from all the second jet pipes can form an upward spiral airflow; the third jet pipe is a third jet pipe with its nozzle facing obliquely upward, and all the third jet pipes are located on the same horizontal plane, and the simultaneous ejection of gas from all the third jet pipes can form an upward spiral airflow; a discharge oblique channel is horizontally opened through the top of the side wall of the inner production cylinder. In the top view, the discharge oblique channel is a discharge oblique channel that is inclined counterclockwise from the inside to the outside. The upward spiral airflow formed by the second jet pipe and the third jet pipe can efficiently agitate and exchange heat in the protein liquid in the early stage of the production process, so that the water in the protein liquid can be evaporated efficiently; in the middle stage of the production process, when a large amount of protein liquid is converted into protein powder clumps that stick together, at this time, a small amount of protein liquid, a large amount of clumps, and a large amount of protein powder coexist. The spiral airflow can blow the light-weight protein powder to a high position near the discharge oblique channel, and enter the discharge oblique channel with the help of the spiral airflow, and finally be ejected from the discharge oblique channel and collected.

[0006] It also includes an exhaust assembly, which includes an exhaust pipe, an external exhaust pipe, and staggered baffles. The top of the inner production cylinder is fixedly connected to the exhaust pipe, and the top of the exhaust pipe is fixedly connected to the external exhaust pipe. The external exhaust pipe can guide the steam out. Several staggered baffles are vertically arranged inside the exhaust pipe. The gaps between the staggered baffles form a tortuous exhaust channel, which can block and intercept a small amount of protein powder carried to a high position by the spiral airflow, preventing the protein powder from being discharged to the outside through the exhaust pipe and causing loss.

[0007] It also includes a material collection assembly, which comprises an outer material collection bucket, a sealing ring, a guide half-pipe, and a stabilizing ring. The outer material collection bucket is a vertically continuous outer material collection bucket. A connecting ring is fixedly installed at the bottom of the inner sidewall of the outer material collection bucket. The inner sidewall of the connecting ring is sealed and fixed to the circumferential sidewall of the bottom plate of the production cylinder. A protein powder collection interlayer is formed between the outer side of the inner production cylinder and the inner side of the outer material collection bucket. A sealing ring is fixedly installed at the top of the inner sidewall of the outer material collection bucket. The annular inner sidewall of the sealing ring is sealed and connected to the top of the outer sidewall of the inner production cylinder. A guide half-pipe is installed at an angle on the inner sidewall of the outer material collection bucket near the discharge inclined channel area. The concave surface of the guide pipe is opposite to the opening of the discharge oblique channel. The protein powder sprayed from the discharge oblique channel can be guided obliquely downward along the concave surface of the guide pipe to the bottom space of the protein powder collection jacket. The bottom ends of all the guide pipes on the side away from the inner wall of the outer collection barrel are connected to the same stabilizing ring. The inner wall of the stabilizing ring is connected and fixed to the outer wall of the inner production cylinder, which can improve the stability of the guide pipe. A support frame is fixedly installed at the bottom of the outer collection barrel. A feed pipe is fixedly connected to the side wall of the inner production cylinder. The feed pipe passes through the side wall of the outer collection barrel and connects to the external protein liquid supply device.

[0008] The first and second jet pipes spray hot air, while the third jet pipe sprays cold air, creating a high-temperature spiral airflow at the bottom of the inner production cylinder to improve solid-liquid separation efficiency. The upper part of the inner production cylinder uses a low-temperature spiral airflow to cool down the swirling solid protein powder, preventing it from sticking together due to high temperature and reducing the moisture content of the protein powder.

[0009] The production assembly also includes a third annular tube, a second annular tube, and a first annular tube. Three annular mounting grooves are provided on the outer wall of the inner production cylinder. The third annular tube, the second annular tube, and the first annular tube are fixedly installed in the annular mounting grooves. The annular mounting grooves can reduce the space occupied by the third annular tube, the second annular tube, and the first annular tube in the protein powder collection jacket. The third annular tube is fixedly connected to the third air jet pipe, the second annular tube is fixedly connected to the second air jet pipe, and the first annular tube is fixedly connected to the first air jet pipe. The third annular tube, the second annular tube, and the first annular tube are respectively connected to the external cold and hot air supply devices after passing through the outer collection bucket via external pipe fittings.

[0010] It also includes a negative pressure discharge assembly, which comprises a fixed frame, a filter screen, a fourth annular pipe, a first negative pressure discharge pipe, and a second discharge pipe. The fixed frame is fixedly installed on the top edge of the connecting ring, and the fixed frame is attached to the inner side wall of the outer collection bucket. A filter screen is fixedly installed on the side of the fixed frame away from the side wall of the outer collection bucket. A fourth annular pipe is fixedly installed on the outer side wall of the outer collection bucket. The fourth annular pipe passes through the side wall of the outer collection bucket using a fitting and communicates with the internal space of the fixed frame. The first negative pressure discharge pipe is fixedly connected to the fourth annular pipe and is connected to an external negative pressure generating device. When the external negative pressure generating device is activated, a negative pressure is formed inside the fixed frame, drawing the protein powder in the protein powder collection interlayer into the fixed frame. Then, the protein powder flows through the fourth annular pipe and is drawn into an external container for storage, for quality inspection and packaging. A small amount of protein powder clumps are intercepted by the filter screen to ensure the quality of the protein powder discharged from the first negative pressure discharge pipe.

[0011] A second discharge pipe is fixedly installed at the bottom of the outer wall of the outer collection bucket. The second discharge pipe is connected to the bottom of the protein powder collection jacket. At the end of the protein powder production process, the second discharge pipe is connected to an external negative pressure generating device to attract and empty the residual impurities in the protein powder collection jacket. At this time, the first negative pressure discharge pipe is connected to an external air supply device to purge the protein powder collection jacket. This allows the residual impurities to be completely discharged, while the filter screen is back-purged, ensuring that the filter screen pores are unobstructed and free from blockage.

[0012] A vibration motor is fixedly installed on the fixed frame. The vibration motor is covered with a protective shell. During the operation of the protein production device, the vibration motor runs continuously and can shake off protein clumps and impurities stuck on the filter screen to ensure the filter screen is unobstructed.

[0013] It also includes a dead-angle baffle assembly. The inner wall of the outer collection bucket is fitted with an inclined guide ring. An isolation cylinder is fixedly installed at the bottom of the inner ring of the inclined guide ring. The inclined guide ring allows the protein powder to slide down smoothly. The isolation cylinder can block the dead corner formed between the fixed frame and the protein powder collection layer, so as to avoid the phenomenon that protein powder, protein powder clumps, and impurities cannot be discharged at the end of the production process.

[0014] The protein powder production method includes the following steps:

[0015] Step 1, Feeding: Using an external protein liquid feeding device, protein liquid is added into the inner production cylinder through the feed pipe;

[0016] Step 2, solid-liquid separation: using external cold and hot air supply devices, air is supplied to the first jet pipe, the second jet pipe, and the third jet pipe to generate a spiral airflow for efficient solid-liquid separation;

[0017] Step 3, protein powder collection: When Step 2 is in progress, a large amount of protein liquid is converted into protein powder clumps that stick together. At this time, a small amount of protein liquid, a large amount of clumps, and a large amount of protein powder coexist. The spiral airflow can blow the light protein powder to a high position near the discharge chute and enter the discharge chute with the help of the spiral airflow. Finally, it is sprayed out from the discharge chute and enters the protein powder collection jacket for collection.

[0018] Step 4, further drying: Connect the first negative pressure discharge pipe to the external air supply device to further dry the protein powder inside the protein powder collection jacket with cold air to ensure the quality of the protein powder output.

[0019] Step 5, Discharge: Disconnect the first negative pressure discharge pipe from the external air supply device, and connect the first negative pressure discharge pipe to the external negative pressure generating device. A negative pressure is formed inside the fixed frame, which draws the protein powder in the protein powder collection interlayer into the fixed frame. Then, the protein powder flows through the fourth annular pipe and is drawn into the external container for storage, in preparation for quality inspection and packaging. A small amount of protein powder clumps are intercepted by the filter screen.

[0020] Step Six, Equipment Evacuation: After the protein powder is emptied, the second discharge pipe is connected to an external negative pressure generating device to draw out the residual impurities in the protein powder collection jacket. At this time, the connection between the first negative pressure discharge pipe and the external negative pressure generating device is disconnected, and the first negative pressure discharge pipe is connected to an external air supply device again to purge the protein powder collection jacket. This ensures that the residual impurities are completely discharged, and the filter screen is back-blown, making the filter screen holes and grooves unobstructed and ready for reuse in production.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] This device is small in size and has a compact structure and small footprint compared to existing protein powder solid-liquid separation production devices.

[0023] This device utilizes a spiral airflow to purge the protein liquid and agglomerated protein powder located at a low position on the bottom plate of the production cylinder. This prevents agglomerated protein powder from adhering to the bottom plate after the production process. It also purges the lighter protein powder to a higher position near the discharge chute, where it enters the chute with the help of the spiral airflow and is finally ejected and collected. This process separates the protein powder from the protein liquid and agglomerated protein powder, allowing for further solid-liquid separation and saving energy. Furthermore, it allows for the addition of protein liquid to the inner production cylinder based on the amount of separated protein powder, enabling continuous production of protein powder without stopping the machine. Compared to existing technologies that perform solid-liquid separation of all protein liquid in the evaporation chamber before sieving for agglomeration, this method achieves more thorough water evaporation and a higher proportion of protein powder in the output.

[0024] This device is equipped with a high-temperature spiral airflow at the bottom of the inner production cylinder to improve solid-liquid separation efficiency, and a low-temperature spiral airflow at the top of the inner production cylinder to cool down the swirling solid protein powder, prevent it from sticking together due to high temperature, and reduce the moisture of the protein powder.

[0025] This device uses negative pressure to draw the protein powder in the protein powder collection jacket into the fixed frame. Then, after the protein powder flows through the fourth annular pipe, it is drawn into an external container for storage, in order to conduct quality inspection and packaging. A small amount of protein powder clumps are intercepted by the filter screen, which improves the quality of the protein powder discharged from the first negative pressure discharge pipe.

[0026] At the end of the protein powder production process, this device uses a second discharge pipe to connect to an external negative pressure generating device to draw out and empty the residual impurities in the protein powder collection jacket for the next startup. At the same time, the first negative pressure discharge pipe is used to purge the protein powder collection jacket, so that the residual impurities can be completely discharged and the filter screen is back-purged to keep the filter screen pores clear for the next startup.

[0027] This device is equipped with a dead-angle baffle component, which can block the dead corners in the protein powder collection interlayer, and prevent the protein powder, protein powder clumps, and impurities from being unable to be discharged at the end of the production process.

7. A method for producing protein powder using the protein powder production apparatus according to any one of claims 1-6, characterized in that: Includes the following steps: Step 1, Feeding: Using an external protein liquid feeding device, protein liquid is added into the inner production cylinder (101) through the feed pipe; Step 2, solid-liquid separation: using external cold and hot air supply devices, air is supplied to the first jet pipe (103), the second jet pipe (104), and the third jet pipe (105) to generate a spiral airflow for efficient solid-liquid separation; Step 3, protein powder collection: When Step 2 is in progress, the protein liquid is converted into a large amount of protein powder clumps that stick together. At this time, a small amount of protein liquid, a large amount of clumps, and a large amount of protein powder coexist. The spiral airflow can blow the light protein powder to a high position near the discharge inclined channel (106) and enter the discharge inclined channel (106) with the help of the spiral airflow. Finally, it is sprayed out from the discharge inclined channel (106) and enters the protein powder collection jacket for collection. Step 4, further drying: Connect the first negative pressure discharge pipe (504) to the external air supply device to further dry the protein powder inside the protein powder collection jacket with cold air to ensure the quality of the protein powder output. Step 5, discharge: disconnect the first negative pressure discharge pipe (504) from the external air supply device, so that the first negative pressure discharge pipe (504) is connected to the external negative pressure generating device, and a negative pressure is formed in the fixed frame (501), which sucks the protein powder in the protein powder collection interlayer into the fixed frame (501). Then, the protein powder flows through the fourth annular pipe (503) and is sucked into the external container for storage, in order to conduct quality inspection and packaging. A small amount of protein powder clumps are intercepted by the filter screen (502). Step 6, Equipment purging: After the protein powder is purged, the second discharge pipe (505) is connected to the external negative pressure generating device to attract and purge the residual impurities in the protein powder collection jacket. At this time, the connection between the first negative pressure discharge pipe (504) and the external negative pressure generating device is disconnected, and the first negative pressure discharge pipe (504) is connected to the external air supply device again to purge the protein powder collection jacket. This allows the residual impurities to be completely discharged, while the filter screen (502) is back-purged, making the filter screen (502) holes and grooves unobstructed and ready for use in production.
