And when protein powder is crude protein powder, the packaging system can effectively reduce the impact of crude protein powder blocking pipeline on crude protein powder packaging and processing, effectively improves the processing efficiency of crude protein powder.

[0047] It should be noted that the packaging system in the present application is not limited to packaging protein powder only, and can also be applied to packaging other powdered materials with a certain particle size. For ease of understanding, the packaging system is used to package crude protein powder, and the packaging system is described below.

[0048] For ease of understanding, Figure 1In the figure, the communication between dust removal inlet 501 and gas phase outlet 102 is not directly indicated, but corresponding wavy lines are provided at gas phase outlet 102 and dust removal inlet 501, to indicate that dust removal inlet 501 is connected with gas phase outlet 102. Since crude protein powder can be used for animal husbandry and there is a certain supply demand, the processing requirements of crude protein powder are also relatively low, so dry protein powder can be carried out certain packaging production after separation by separator 1, and the mill 2 between silo 3 and separator 1 can improve the processing quality of crude protein powder, and the use and maintenance cost of packaging system will not be excessively increased, and the quality of crude protein powder obtained by processing is effectively improved. And each equipment and device in the packaging system is relatively common, and the recovery packaging of crude protein powder is realized with a relatively simple structure, and the overall use and maintenance cost is also relatively low, and the production efficiency of crude protein powder can also be improved. In the present application, protein powder is a kind of powdered material. The packaging system provided by the present application can process and package protein powder with a particle size of 3 mm to 4 cm. Protein powder in this particle size range is crude protein powder. The crude protein powder can be processed using the present application with high processing efficiency and low maintenance costs, and can also obtain protein powder of better quality.

[0049] In some or certain embodiments, the packaging system can also be used as the last steps in the protein powder production process, for example, the raw material inlet 101 of the separator 1 can be directly connected to the drying device for drying the protein powder. After the separator 1 receives the protein powder dried by the drying device, the crude protein powder is subjected to basic processing and packaging, and the crude protein powder packaged in the powder packaging machine 4 can be put into production.

[0050] In some or certain embodiments, the separator 1 may be a cyclone separator 1. It is easy to obtain and can meet the requirements of gas-solid separation of crude protein powder, and the overall use cost is also low. The raw material inlet 101 of the separator 1 is usually provided with a control valve 8 for controlling the opening and closing of the raw material inlet 101.

After the impurities of the iron filings in the crude protein powder are removed, the quality of the protein powder can be improved. The protein powder with impurities removed can flow out from the material outlet 602 of the iron remover 6 and enter the mill 2. When the second feed inlet 306 of the silo 3 is connected to the solid phase outlet 103 of the separator 1, the crude protein powder with some impurities removed by the iron remover 6 can also enter the second feed inlet 306 of the silo 3 from the material outlet 602 of the iron remover 6. The protein powder flowing out of the separator 1 can be made to remove impurities through the iron remover 6, which is conducive to improving the quality of the crude protein powder.

[0054] In some or certain embodiments, the iron remover 6 may be a pneumatic iron remover, such as a Gaussian fully automatic dry powder iron remover, a Gaussian fully automatic iron remover, or a Gaussian fully automatic self-unloading drawer iron remover, etc. It is easy to obtain and has a good iron removal effect on powder materials such as protein powder, and will not affect the normal feeding of protein powder.

[0055] In some or certain embodiments, the separator 1 may also adopt a separator 1 that uses different principles and can separate protein powder and gas, and the iron remover 6 may also adopt a permanent magnetic iron remover, etc., and may also remove impurities such as iron filings that may be mixed in the protein powder. In some or certain embodiments, the solid phase outlet 103 of the separator 1 may also be directly connected to the mill 2 and the silo 3 through a pipeline and a valve, etc., and may also meet the recovery and packaging of the crude protein powder.

[0056] In some or certain embodiments, the material outlet 602 and the feed port 201 , and the material outlet 602 and the second feed port 306 are both connected through corresponding connecting pipes 7 whose on / off can be controlled.

[0057] The on-off controllable connecting pipe 7 can realize the connection and disconnection between the material outlet 602 of the iron remover 6 and the feed inlet 201 of the grinding mill 2, and between the material outlet 602 of the iron remover 6 and the silo 3, which can facilitate the control of the feeding process of the protein powder.

[0058] In some or certain embodiments, the on and off of the connecting pipe 7 is controllable, which can be achieved by setting a corresponding control valve 8 on the connecting pipe 7. The control valve 8 set on the connecting pipe 7 between two different devices can be a butterfly valve, a rotary valve, or a solenoid valve, etc.

[0059] In some or certain embodiments, the packaging system further includes a hand hole (not shown) corresponding to each connecting tube 7. Even if the connecting tube 7 is blocked, the internal blockage of the connecting tube 7 can be cleaned through the hand hole, which is conducive to the rapid resumption of normal production of the production line where the protein powder is located.

[0060] It should be noted that the hand hole is a reduced manhole, which is installed for the purpose of installing, disassembling, cleaning and repairing the internal devices of the equipment.

And the first pipeline 9, the connecting pipe 7, and the second pipeline 10 are all provided with hand holes. The method in this section is adopted to realize the communication between each device in each packaging system, which is convenient for controlling the processing and feeding process of crude protein powder, and the pipelines between the mill 2 and the silo 3, and between the silo 3 and the iron remover 6 are all provided with hand holes. In the case that the crude protein powder may be blocked, it is also convenient to insert tools through the hand holes to clean the corresponding connecting pipe 7 or the first pipeline 9, the inside of the second pipeline 10, so as to quickly restore the normal operation of the production line where the protein powder is located.

[0062] In some or certain embodiments, the silo 3 may include a cylindrical body 303 and two heads 304 that close the two ends of the cylindrical body 303. The first and second feed ports of the silo 3 may be set in one of the heads 304, and the discharge port 302 may be opened in the other head 304 of the silo 3. The silo 3 may also include a level meter 305 set at both ends of the cylindrical body 303. The silo 3 adopts this structure, which is relatively simple, and the axis of the cylindrical body 303 can be set along the gravity direction of the environment where the silo 3 is located when the silo 3 is in use. The level meter 305 at both ends of the cylindrical body 303 can detect the corresponding signal when the thickness of the protein powder in the silo 3 reaches a certain height or decreases to a certain height. According to the signal detected by the level meter 305, the start and stop of the separator 1 or the mill 2 or the powder packaging machine 4 and other equipment can be controlled to improve the safety and automation of the protein recovery and packaging system.

[0063] In some or certain embodiments, the minimum distance between the iron remover 6 and the separator 1 may be 45-55 cm, and the maximum distance between the material level meter 305 and the two sealing heads 304 may be 15-25 cm.

The powder packaging machine 4 can be a Himmler Toledo LCS computer automatic quantitative packaging machine, which has a better effect on the processing and packaging of the protein powder, and is conducive to improving the processing quality of the protein powder.

[0065] In some or certain embodiments, the dust recovery device 5 is a bag collector, the inlet of the bag collector is configured as a dust collection inlet 501, and the bag collector is also provided with a first outlet 502 for gas discharge and a second outlet 503 for powder discharge, and the second outlet 503 is connected to the raw material inlet 101.

[0066] Bag filter is easy to obtain, and is applied in the recovery process of protein powder, the crude protein powder entering from the entrance of bag filter can be filtered by bag filter, crude protein powder can be filtered and retained in bag filter, and can flow out from the second outlet 503 of bag filter, enter the raw material import 101 connected to the second outlet 503, for the recovery and packaging of protein powder again, the recovery effect of protein powder can be improved. The protein powder overflowing from powder packaging machine 4 can flow out from the first outlet 502 of bag filter after being filtered by bag filter. In some or certain embodiments, the gas flowing out of the first outlet 502 can enter water film dust removal equipment or device etc.

[0067] In some or certain embodiments, the bag filter may be a bag filter 1320*1320*4500, and a spraying device (not shown) may be provided on the bag filter, and the blowing device may spray the protein powder filtered by the bag filter to the second outlet 503, so that the protein powder quickly enters the raw material inlet 101. The blowing device may include a pulse valve, a blowing pipe, an air bag and a control logic valve, etc., for cleaning the protein powder filtered by the bag.

[0068] In some or certain embodiments, the packaging system further comprises a dust removal fan 12, and the fan inlet 1201 is connected to the first outlet 502. The dust removal fan 12 can be used to put the bag filter in a negative pressure state, thereby accelerating the collection and utilization of the scattered protein powder.

[0069] In some or certain embodiments, the dust removal recovery device 5 is also used to capture powder scattered by the powder packaging machine 4 through the dust removal inlet 501. In the case where the powder material received by the powder packaging machine 4 is protein powder, the protein powder scattered during the packaging process of the powder packaging machine 4 is captured to improve the safety of the protein powder recovery and packaging process. The following is a description of the case where the powder is protein powder.

[0070] In some or certain embodiments, the dust removal and recovery device 5 is also used to capture the protein powder released from the powder packaging machine 4 through the dust removal inlet 501. One pipe opening of a multi-way connector can be used to connect to the dust removal inlet 501, and then the other pipe openings of the multi-way connector are connected to the gas phase outlet 102 or the position where the protein powder is easily released from the powder packaging machine 4 through corresponding pipes or pipelines, so as to capture the protein powder released from the powder packaging machine 4.

[0071] It should be noted that for powder packaging machines 4 of models and specifications such as the Himmler Toledo LCS computer automatic quantitative packaging machine, the Savo automatic quantitative weighing packaging machine SW-KL60, etc., this type of powder packaging machine 4 is prone to leaking protein powder at the packaging machine's feed port and other locations.

[0072] In some or certain embodiments, the powder packaging machine 4 can also be placed in the packaging room, and the dust removal and recovery device 5 can be placed in a small dust removal room opposite to the packaging room. The dust removal inlet 501 can be connected to the packaging room through a pipe to capture the protein powder emitted by the powder packaging machine 4 in the packaging room.

[0073] Figure 2 A flow chart of a control method of a packaging system in some embodiments or certain embodiments of the present application is shown, with reference to Figure 2 The present application also provides a control method for a packaging system, the control method is implemented by the packaging system as described above, and the control method includes:

[0074] S101: The raw material inlet of the separator receives the dry protein powder.

[0075] S102: Determine the grinding time of the grinding mill according to the feeding time of the separator.

[0076] The structure of the packaging system and its corresponding technical effects can be referred to above, and will not be repeated here. The raw material inlet of the separator receives the dry protein powder, and the separator begins to separate the dry protein powder. The separated protein powder flowing out of the solid phase outlet of the separator enters the mill, and the milling time of the mill is determined according to the unloading time of the separator, so that the mill can effectively grind the received protein powder within the corresponding time. After the grinding is completed, the separator can be controlled to carry out subsequent unloading and continued grinding.

[0077] In some or certain embodiments, the packaging system is further provided with an iron remover, which is connected to the mill through a feed pipe, and the feed pipe is provided with a control valve for a rotary valve. The feed duration of the separator corresponds to the opening duration of the control valve, and the opening duration of the control valve can be the duration from when the rotary valve receives an opening signal until the rotary valve receives a closing signal. The grinding duration of the mill can be the duration from when the motor of the mill receives a start-of-work signal until the motor of the mill receives a stop-work signal.

[0078] In some or certain embodiments, determining the milling time of the mill according to the feeding time of the separator may include: determining the milling time of the mill according to the feeding time of the separator based on a mapping relationship between the feeding time of the separator and the milling time of the mill. The efficiency is high and the quality of the protein obtained by milling is good.

[0079] It should be noted that the mapping relationship between the discharge time of the separator and the grinding time of the mill can be obtained by conducting multiple tests under the condition that the frequency of the motor in the mill is at a certain fixed frequency.

[0080] In some or certain embodiments, the unloading time of the separator may be the same as the grinding time of the mill, for example, the unloading time of the separator is 10 min or 20 min, and the grinding time of the mill can be determined as the corresponding data. After the mill completes the grinding and discharging, the separator can continue to receive the dry protein powder, and then the mill is controlled to grind the protein powder.

[0081] In some or certain embodiments, the solid phase outlet of the separator is connected to the feed inlet of the silo through a connecting pipe, and the connecting pipe is provided with a butterfly valve for controlling the opening and closing of the connecting pipe. If the mill fails, the control method may further include:

[0082] According to the fault signal of the mill, the butterfly valve is opened and the rotary valve is closed; after the rotary valve is closed for a set time, the mill is controlled to discharge materials; the mill is controlled to stop. The mill can be emptied for easy maintenance.

[0083] In some or certain embodiments, the control method may further include:

[0084] The start and stop of the powder packaging machine is controlled according to the height signal of the protein powder accumulated in the silo.

[0085] Controlling the start and stop of the powder packaging machine according to the height signal of the protein powder is beneficial to controlling the height of the protein powder in the silo, so as to ensure the stable operation of the entire packaging system and improve the working efficiency of the protein powder.

[0086] In some or certain embodiments, the structure of the silo can refer to the above-mentioned, when the height of the protein powder in the silo reaches the measuring position of the material level meter with the maximum height, the powder packaging machine starts to work to pack the protein powder in the silo, and the dust removal recovery device can also be started to work; when the height of the protein powder in the silo reaches the measuring position of the material level meter with the lowest height, the packaging machine can be controlled to stop, and the dust removal recovery device can also be turned off. The height of the protein powder in the silo can be controlled to be more stable. When the protein powder reaches the upper limit of the height in the silo, a corresponding alarm signal such as an electric bell 13 can be issued. The electric bell 13 can be electrically connected to the material level meter. For some powder packaging machines that require manual cooperation, this operation gives the operator a rest time, and can also reduce the occurrence of situations such as the motor burning out caused by the equipment working for a long time.

[0087] In some or certain embodiments, when the mill is shut down, the connection between the mill and the separator may also be cut off, and when the packaging machine is shut down, the dust recovery device which is a bag dust collector may also be shut down.

[0088] The present application also provides a control system for a packaging system, the control system is used to control the packaging system as described above, and the control system includes:

[0089] A control unit is used to enable the raw material inlet of the separator to receive the dry protein powder.
