Description

Technical Field

[0001] The invention relates to the technical field of automated production equipment, and in particular to a freeze-dried ball dispensing device. Background Art

[0002] Freeze-dried balls are small solid balls that are quickly frozen into shape by being pumped into liquid nitrogen through a professional precision micro pump at a very short and low temperature. Freeze-dried balls are mainly used in the fields of medical diagnosis, beauty and skin care. In the production process of freeze-dried balls, the freeze-dried balls need to be quickly packaged into containers for sealed storage after they are formed to prevent them from absorbing moisture.

[0003] In the prior art, freeze-dried balls are mostly stored by vacuum adsorption with flexible vibration plate and visual screening.

[0017] And / or, an exhaust channel is provided on the base, one end of the exhaust channel is connected to the blocking space, and the other end of the exhaust channel is connected to the external space.

[0018] As an optional solution of the freeze-dried ball dispensing device of the present invention, a limiting groove is provided at one end of the blocking plate extending into the dispensing channel, and when in the first position, the freeze-dried balls in the blocking space can be confined in the limiting groove;

[0022] As an optional solution of the freeze-dried ball dispensing equipment of the present invention, the accommodating chamber includes a first chamber and a second chamber that are connected, the second chamber is closer to the base, and the cross-sectional area of ​​the second chamber gradually decreases toward the base to form an inclined guide wall in the second chamber, and the second air inlet channel is inclined to the storage bin, and the inclination angle of the second air inlet channel is the same or approximately the same as the inclination angle of the guide wall.

When the freeze-dried balls in the accommodating chamber enter the distribution channel and reach the blocking space, the first detection member can detect that there are freeze-dried balls in the blocking space. At this time, the blocking plate is controlled to move from the first position to the second position, so that the distribution channel is conductive, and the restraining force of the blocking plate on the freeze-dried balls disappears. The freeze-dried balls in the blocking space then automatically enter the equipment of the next processing step (such as freeze-dried ball screening equipment) along the distribution channel or fall into the container for the freeze-dried balls. When the freeze-dried balls leave the blocking space, the first detection member detects that there are no freeze-dried balls in the blocking space.

[0027] Since the blocking space can only accommodate a single freeze-dried ball, only one freeze-dried ball can fall into the equipment of the next process or into the container for the freeze-dried balls at a time, thereby accurately controlling the number of freeze-dried balls to be distributed. The setting of the first detection part can control the movement of the blocking plate according to whether there are freeze-dried balls in the blocking space, thereby realizing fully automatic distribution of freeze-dried balls and ensuring the accuracy of distribution. At the same time, during the distribution process of the freeze-dried ball distribution equipment, the freeze-dried balls are always in the closed environment of the containing cavity and the distribution channel, which can isolate the external environment, avoid cross contamination caused by contact between the freeze-dried balls and foreign objects, and ensure the distribution quality of the freeze-dried balls.

[0047] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance. Among them, the terms "first position" and "second position" are two different positions.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0050] like Figures 1 to 6 As shown, this embodiment provides a freeze-dried ball dispensing device, which can realize the dispensing and storage of freeze-dried balls 100 and prevent the freeze-dried balls 100 from being contaminated. The freeze-dried ball dispensing device includes a storage bin 1, a base 2, a blocking mechanism 3 and a first detection member 4.

[0051] Among them, see Figure 1 and Figure 3 The storage bin 1 has a receiving cavity 111 for containing freeze-dried balls 100. The base 2 is arranged below the storage bin 1. The base 2 is provided with a dispensing channel 21 connected with the receiving cavity 111. The lateral space of the dispensing channel 21 only allows a single freeze-dried ball 100 to pass through. The blocking mechanism 3 includes a blocking plate 31 movably arranged on the base 2. The blocking plate 31 has a first position and a second position. In the first position, the blocking plate 31 extends into the dispensing channel 21 and encloses a blocking space 5 in the dispensing channel 21 for blocking a single freeze-dried ball 100. In the second position, the blocking plate 31 avoids the dispensing channel 21 to allow a single freeze-dried ball 100 to pass through the dispensing channel 21. The first detection member 4 is used to detect whether there is a freeze-dried ball 100 in the blocking space 5. When the first detection member 4 detects that there is a freeze-dried ball 100 in the blocking space 5, the blocking plate 31 moves from the first position to the second position.

[0052] The freeze-dried ball dispensing equipment provided in this embodiment is as follows: Figure 3 and Figure 4 As shown, when the blocking plate 31 is in the first position, a blocking space 5 is formed in the material distribution channel 21. When the freeze-dried balls 100 in the accommodating chamber 111 enter the material distribution channel 21 and reach the blocking space 5, the first detection element 4 can detect that there are freeze-dried balls 100 in the blocking space 5. At this time, the blocking plate 31 is controlled to move from the first position to the second position, so that the material distribution channel 21 is conductive (as shown in FIG. Figure 5As shown in the figure, the restraining force of the blocking plate 31 on the freeze-dried balls 100 disappears, and the freeze-dried balls 100 in the blocking space 5 automatically enter the equipment of the next processing step (such as the freeze-dried ball 100 screening equipment) along the distribution channel 21 or fall into the container containing the freeze-dried balls 100. When the freeze-dried balls 100 leave the blocking space 5, the first detection element 4 detects that there are no freeze-dried balls 100 in the blocking space 5. At this time, the blocking plate 31 is controlled to move from the second position to the first position, and the blocking space 5 is re-formed in the distribution channel 21. The distribution of the freeze-dried balls 100 is realized in this cycle.

[0053] Since the blocking space 5 can only accommodate a single freeze-dried ball 100, only one freeze-dried ball 100 can fall into the equipment of the next process or into the container containing the freeze-dried balls 100 at a time, so as to accurately control the number of freeze-dried balls 100 to be distributed. The setting of the first detection member 4 can control the movement of the blocking plate 31 according to whether there are freeze-dried balls 100 in the blocking space 5, so as to realize the full-automatic distribution of the freeze-dried balls 100 and ensure the accuracy of the distribution. At the same time, during the distribution process of the freeze-dried ball distribution equipment, the freeze-dried balls 100 are always in the closed environment of the accommodating chamber 111 and the distribution channel 21, which can isolate the external environment, avoid cross contamination caused by contact between the freeze-dried balls 100 and foreign objects, and ensure the distribution quality of the freeze-dried balls 100.

[0054] In this embodiment, the width of the distribution channel 21 is defined as D, and the diameter of the freeze-dried ball 100 is defined as d, d<D<2d, so as to ensure that the lateral space of the distribution channel 21 only allows a single freeze-dried ball 100 to pass through, and the freeze-dried ball 100 can be ensured to move smoothly in the distribution channel 21. Exemplarily, the width of the distribution channel 21 is 0.2 mm larger than the diameter of the freeze-dried ball 100.

[0055] In addition, the diameter of the material distribution channel 21 is designed to be slightly larger, which can be compatible with the material distribution operation of freeze-dried balls 100 with different diameters within a certain range, thereby improving the versatility of the freeze-dried ball distribution device. For example, if D is 25 mm, freeze-dried balls 100 with diameters within the range of 12.6 mm to 24.9 mm can be distributed by the material distribution device.

[0056] Optionally, see Figure 2 The first detection member 4 is mounted on the base 2, and the detection end of the first detection member 4 is located in the blocking space 5. Further, the first detection member 4 includes an optical fiber detection element, which can detect whether there is a freeze-dried ball 100 in the blocking space 5. That is, the presence of the freeze-dried ball 100 in the blocking space 5 is determined by optical fiber detection, and the detection efficiency is high and the detection is accurate.

[0057] For example, the optical fiber detection element is an optical fiber sensor, whose working principle is to send the incident light beam from the light source into the modulator through the optical fiber, and interact with the external measured parameters in the modulator to change the optical properties of the light, such as the intensity, wavelength, frequency, phase, polarization state, etc., to become a modulated optical signal, which is then sent to the optoelectronic device through the optical fiber and obtained after the demodulator. The optical fiber sensor has high detection sensitivity and good reliability.

[0058] In other embodiments, the first detection element 4 may also be an infrared sensor, etc., and the infrared sensor is used to detect whether the freeze-dried balls 100 are in the blocking space 5.

[0059] Optionally, see Figure 3 , Figure 4 and Figure 5 The material distribution channel 21 includes a first channel 211, a second channel 212 and a third channel 213 which are connected in sequence. The first channel 211 is connected to the accommodating chamber 111. The second channel 212 is inclined relative to the horizontal plane and has a slope toward the first channel 211. In the first position, the blocking plate 31 extends into the third channel 213 and is surrounded at the connection between the third channel 213 and the second channel 212 to form a blocking space 5, that is, the blocking space 5 is located at the higher end of the second channel 212 ( Figure 3 The freeze-dried balls 100 in the receiving chamber 111 are located at the lower end of the second channel 212 after entering from the first channel 211 ( Figure 3 Since the blocking space 5 can only accommodate one freeze-dried ball 100 and the second channel 212 has a slope, only one freeze-dried ball 100 can be temporarily stored in the blocking space 5 at a time, and the remaining freeze-dried balls 100 can only stay in the first channel 211 and the connection between the first channel 211 and the second channel 212. In this way, after the blocking plate 31 is switched to the second position, it can be further ensured that only one freeze-dried ball 100 can be output from the third channel 213, and the amount of freeze-dried balls 100 distributed can be accurately controlled.

[0060] In this embodiment, Figure 3 and 5 As shown, the second channel 212 is arranged horizontally and tilted, and the first channel 211 and the third channel 213 are arranged vertically. With this arrangement, the freeze-dried ball 100 can smoothly fall from the accommodating chamber 111 into the first channel 211 under the action of its own gravity, and the freeze-dried ball 100 in the blocking space 5 can also smoothly fall into the third channel 213 under the action of its own gravity, thereby improving the material distribution efficiency.

[0061] In other embodiments, the first channel 211 and the third channel 213 may also be designed to be slightly inclined, as long as the freeze-dried balls 100 can fall freely.

[0062] Optionally, see Figure 3 and Figure 4 The inner wall of the second channel 212 and the inner wall of the third channel 213 are connected in an arc-shaped transition to form an arc-shaped blocking surface 214. A blocking space 5 is formed between the arc-shaped blocking surface 214 and the blocking plate 31. Figure 4 As shown, when the blocking plate 31 is in the first position, the arcuate blocking surface 214 is located above the blocking plate 31. The setting of the arcuate blocking surface 214 makes the shape of the blocking space 5 more suitable for the spherical freeze-dried ball 100, which can prevent the freeze-dried ball 100 from being stuck in the blocking space 5. After the blocking plate 31 is switched to the second position, it is ensured that the freeze-dried ball 100 can smoothly fall into the third channel 213. At the same time, the concave arc surface of the arcuate blocking surface 214 can prevent the freeze-dried ball 100 from being scratched and damaged. The curvature of the arcuate blocking surface 214 can be designed according to the diameter of the freeze-dried ball 100, as long as it is ensured that only a single freeze-dried ball 100 is allowed to exist in the blocking space 5.

[0063] Further, see 3 and Figure 4 The first channel 211 and the second channel 212 are connected at the corner with an arc chamfer 215, and the third channel 213 and the second channel 212 are connected at the corner with an arc chamfer 215. That is, the arc chamfer 215 is processed at the positions where there are sharp points at the corners of the material distribution channel 21, which can further prevent the freeze-dried balls 100 from being scratched when flowing in the material distribution channel 21. The arc chamfer 215 includes an inner arc chamfer and an outer arc chamfer.

[0064] See also Figure 3 and Figure 5 An access port 25 is provided on the base 2 below the third channel 213. The access port 25 is used to connect with the freeze-dried ball screening device of the next processing step. The freeze-dried balls 100 flowing out of the third channel 213 will enter the freeze-dried ball screening device for a second material sorting and screening, so as to further control the number of freeze-dried balls sorted and ensure that the number of freeze-dried balls entering the freeze-dried ball storage container at a single time is accurate.

[0065] Optionally, see Figure 3 , Figure 4 and Figure 5The freeze-dried ball dispensing device also includes a first blowing mechanism 6 disposed on the base 2. The connection between the second channel 212 and the first channel 211 forms a cache space 10 for caching the freeze-dried balls 100. The air outlet of the first blowing mechanism 6 is connected to the cache space 10, and is used to blow air into the cache space 10, so that the freeze-dried balls 100 in the cache space 10 are moved to the blocking space 5. The method of driving the freeze-dried balls 100 from the cache space 10 to the blocking space 5 by blowing can prevent foreign objects from directly contacting the freeze-dried balls 100, and further prevent the freeze-dried balls 100 from being contaminated. At the same time, the airflow driving method is relatively gentle, which can prevent the freeze-dried balls 100 from being damaged or falling off, and ensure the quality of the freeze-dried balls 100.

[0066] In this embodiment, the angle between the second channel 212 and the horizontal plane is defined as α, and the value range of α is: 0°<α≤10°, so that the second channel 212 has a slope and the slope is not too large, ensuring that the first blowing mechanism 6 can smoothly send the freeze-dried balls 100 into the blocking space 5. Exemplarily, α is 7.5°. In other embodiments, α is also 3°, 4°, 5°, 6°, 7°, 8°, etc.

[0067] Exemplarily, the first blowing mechanism 6 may be an air pump or the like, as long as it can generate a stable airflow.

[0068] Optionally, see Figure 3 and Figure 4 The base 2 is provided with a first air inlet channel 22, one end of which is connected to the air outlet of the first blowing mechanism 6, and the other end is connected to the buffer space 10, and the air outlet direction of the first air inlet channel 22 is toward the blocking space 5. The airflow generated by the first blowing mechanism 6 enters the buffer space 10 through the first air inlet channel 22, and the freeze-dried balls 100 in the buffer space 10 can move along the second channel 212 to the blocking space 5 under the driving action of the airflow. That is, the setting of the first air inlet channel 22 can limit the flow direction of the airflow, so that the airflow flows toward the blocking space 5, thereby driving the freeze-dried balls 100 to smoothly enter the blocking space 5 from the buffer space 10.

[0069] Continue reading Figure 3 and Figure 4 Optionally, an exhaust channel 23 is provided on the base 2, one end of the exhaust channel 23 is connected to the blocking space 5, and the other end of the exhaust channel 23 is connected to the external space. The airflow reaching the blocking space 5 can be discharged to the outside through the exhaust channel 23, thereby preventing the airflow from flowing back and causing the freeze-dried balls 100 to roll back into the second channel 212, ensuring that the freeze-dried balls 100 can be stably temporarily stored in the blocking space 5.

[0070] Optionally, see Figure 3 , Figure 4 and Figure 5, a limiting groove 311 is provided at one end of the blocking plate 31 extending into the material distribution channel 21. When in the first position, the freeze-dried ball 100 in the blocking space 5 can be limited by the limiting groove 311, so that the freeze-dried ball 100 can be temporarily stored in the blocking space 5 stably. In this embodiment, after the freeze-dried ball 100 reaches the blocking space 5, a part of it is located in the limiting groove 311, and the center of gravity of the freeze-dried ball 100 falls in the limiting groove 311, that is, the center of gravity of the freeze-dried ball 100 is in the third channel 21 (that is, the center of gravity of the freeze-dried ball 100 deviates from the second channel 212). When the blocking plate 31 moves from the first position to the second position, the freeze-dried ball 100 can fall rapidly under the action of its own gravity, effectively improving the falling efficiency of the freeze-dried ball 100, while ensuring that the freeze-dried ball 100 will not fall back to the second channel 212.

[0071] In this embodiment, the groove wall of the limiting groove 311 is an arcuate surface to adapt to the shape of the freeze-dried ball 100, so that the freeze-dried ball 100 can be temporarily stored in the limiting groove 311 more stably. At the same time, the arcuate surface can prevent the freeze-dried ball 100 from being scratched, thereby ensuring the quality of the freeze-dried ball 100 after distribution.

[0072] Optionally, see Figure 3 and Figure 4 The base 2 is provided with a through hole 24 connected to the third channel 213, and the blocking plate 31 can move linearly in the through hole 24 to switch between the first position and the second position. Exemplarily, the extension direction of the through hole 24 is perpendicular to the extension direction of the third channel 213, so that the blocking plate 31 can effectively block the third channel 213.

[0073] Further, see Figure 1 , Figure 2 and Figure 3 The blocking mechanism 3 further includes a driving member 32, a mounting base 33 and a guide member 34. The blocking plate 31 is fixed on the mounting base 33. One end of the guide member 34 is fixedly connected to the mounting base 33, and the other end is slidably connected to the base 2 along the moving direction of the blocking plate 31. The driving member 32 is fixed to the base 2, and the output end of the driving member 32 is connected to the mounting base 33. The driving member 32 can drive the mounting base 33 to drive the blocking plate 31 to move in the through hole 24. The setting of the guide member 34 can guide the moving direction of the mounting base 33, thereby ensuring the moving stability of the blocking plate 31 in the through hole 24.

[0074] Optionally, a floating joint is provided at the output end of the driving member 32, and the floating joint is connected to the mounting base 33. The floating joint can eliminate the error caused by eccentricity or insufficient parallelism between the driving member 32 and the mounting base 33, improve the movement accuracy of the mounting base 33, and ensure that the blocking plate 31 can accurately switch between the first position and the second position.

[0075] In this embodiment, the freeze-dried ball dispensing device further includes a control module, and the first detection member 4 and the driving member 32 are both in communication connection with the control module, and the control module controls the opening and closing of the driving member 32 according to the information detected by the first detection member 4, so as to realize automatic control of the blocking plate 31 to switch between the first position and the second position. Exemplarily, the driving member 32 is a linear driving mechanism such as a cylinder or an electric cylinder.

[0076] In other embodiments, the blocking plate 31 may also be switched between the first position and the second position by rotation.

[0077] Optionally, see Figure 3 , Figure 5 and Figure 6 The freeze-dried ball dispensing device further includes a second blowing mechanism 7 disposed in the storage bin 1, and the air outlet of the second blowing mechanism 7 is connected to the accommodating chamber 111, and is used to blow air into the accommodating chamber 111 to move the freeze-dried balls 100 in the accommodating chamber 111. Blowing air into the accommodating chamber 111 by the second blowing mechanism 7 can move the multiple freeze-dried balls 100 in the accommodating chamber 111, prevent the freeze-dried balls 100 from being adsorbed together due to static electricity, and ensure that the freeze-dried balls 100 can smoothly fall into the dispensing channel 21. Exemplarily, the second blowing mechanism 7 can be an air pump, etc.

[0078] Furthermore, the second blowing mechanism 7 can be communicatively connected with the control module. When the first detection component 4 detects that there are no freeze-dried balls 100 in the blocking space 5 for a long time and the first blowing mechanism 6 works normally, it can be determined that there is a situation where the balls do not fall into the accommodating chamber 111. At this time, the second blowing mechanism 7 is controlled to start blowing air into the accommodating chamber 111 to release the freeze-dried balls 100 from the aggregation state and ensure that the balls fall normally.

[0079] Optionally, see Figure 6 The storage bin 1 is provided with a second air inlet channel 112, and the accommodating chamber 111 has a discharge port. One end of the second air inlet channel 112 is connected to the air outlet end of the second blowing mechanism 7, and the other end is connected to the discharge port of the accommodating chamber 111. The airflow generated by the second blowing mechanism 7 is passed into the accommodating chamber 111 via the second air inlet channel 112, and the multiple freeze-dried balls 100 in the accommodating chamber 111 can be dispersed under the action of the airflow. The second air inlet channel 112 can concentrate the airflow to the accommodating chamber 111 to ensure the blowing effect. Connecting the second air inlet channel 112 to the discharge port can allow the airflow to pass from the bottom of the accommodating chamber 111, thereby preventing the freeze-dried balls 100 from gathering at the discharge port and ensuring normal ball falling.

[0080] Exemplarily, the diameter of the second air inlet channel 112 ranges from 0.3 mm to 1 mm, ensuring that the airflow blowing toward the receiving chamber 111 has a certain force so that the multiple freeze-dried balls 100 can be dispersed. For example, the diameter of the second air inlet channel 112 is 0.5 mm.

[0081] Optionally, see Figure 3 and 5 The accommodating chamber 111 includes a first chamber and a second chamber that are connected, the second chamber is closer to the base 2, and the cross-sectional area of ​​the second chamber gradually decreases toward the base 2, so as to form an inclined flow guide wall 113 in the second chamber. That is, the second chamber is funnel-shaped, so that the freeze-dried balls 100 can automatically gather downward under the action of their own gravity and fall into the material distribution channel 21, thereby improving the ball falling efficiency.

[0082] Further, see Figure 6 , the second air inlet channel 112 is tiltedly arranged on the storage bin 1, and the inclination angle of the second air inlet channel 112 is the same or approximately the same as the inclination angle of the guide wall 113. The second air inlet channel 112 is designed to be consistent or approximately consistent with the inclination of the guide wall 113, so that the airflow can act on more freeze-dried balls 100, thereby quickly breaking the aggregation state of the freeze-dried balls 100 and ensuring normal ball falling. The approximately the same here means that the second air inlet channel 112 is roughly parallel to the guide wall 113 surface, for example, the difference in the inclination angle between the two can be within 5°.

[0083] See also Figure 3 and Figure 5 and Figure 6 The storage bin 1 is provided with a discharge channel 114, the accommodating chamber 111 has a discharge port, one end of the discharge channel 114 is connected to the discharge port, and the other end is connected to the distribution channel 21. In this embodiment, the discharge channel 114 also only allows a single freeze-dried ball 100 to pass through, and the freeze-dried ball 100 first falls into the discharge channel 114 from the discharge port for buffering and then enters the distribution channel 21, which can make the freeze-dried ball 100 in the distribution channel 21 move more smoothly.

[0084] Optionally, see Figure 1 and Figure 3 The freeze-dried ball dispensing device also includes a second detection member 8, which is used to detect the amount of remaining freeze-dried balls in the accommodating chamber 111. When the second detection member 8 detects that the amount of remaining freeze-dried balls in the accommodating chamber 111 is lower than a set threshold, the freeze-dried ball dispensing device sends a prompt signal. The provision of the second detection member 8 enables the staff to grasp the amount of remaining freeze-dried balls in the accommodating chamber 111. When the freeze-dried ball dispensing device sends a prompt signal, it indicates that the number of freeze-dried balls 100 in the accommodating chamber 111 is small, which is convenient for the staff to timely refill the accommodating chamber 111, thereby ensuring the working continuity of the freeze-dried ball dispensing device and improving the dispensing efficiency. Among them, the refilling can be manual or automatic.

[0085] In this embodiment, the second detection element 8 includes an optical fiber detection element, that is, the remaining amount of the freeze-dried balls 100 in the receiving chamber 111 is determined by optical fiber detection, which has high detection efficiency and is accurate. Figure 1 and Figure 3 The second detection member 8 is obliquely installed on the storage bin 1, and the detection end of the second detection member 8 is located in the accommodating cavity 111. The range that the second detection member 8 can detect is Figure 3 The area above the middle dotted line is when the remaining amount of the freeze-dried balls 100 in the receiving chamber 111 is not enough to cover the Figure 3 When the height of the intersection of the dotted line in FIG. 1 and the guide wall 113 is reached, the second detection element 8 cannot detect the freeze-dried balls 100. At this time, it is determined that the amount of remaining freeze-dried balls in the accommodating chamber 111 is lower than the set threshold.

[0086] Furthermore, the detection range can be adjusted by adjusting the inclination angle of the second detection member 8, thereby adjusting the size of the above-mentioned set threshold. The installation inclination of the second detection member 8 can be determined according to factors such as the size of the freeze-dried balls 100, as long as a certain amount of freeze-dried balls 100 in the accommodating chamber 111 is ensured to maintain uninterrupted material distribution.

[0087] Optionally, see Figure 1 and Figure 6 The freeze-dried ball dispensing device further includes an observation window 9 disposed on the base 2, and a dispensing channel 21 is recessed on a side of the base 2 facing the observation window 9. The observation window 9 is made of a transparent material, and the freeze-dried balls 100 in the dispensing channel 21 can be observed through the observation window 9. With such an arrangement, the staff can observe the dispensing status of the freeze-dried balls 100 in real time, and can promptly detect faults and take corresponding measures.

[0088] Exemplarily, the observation window 9 is made of a transparent acrylic material, which has a good perspective effect, strong structural strength and a long service life.

[0089] Furthermore, the observation window 9 can be detachably mounted on the base 2, so that the disassembly of the observation window 9 is convenient for cleaning the material distribution channel 21. In this embodiment, a magnetic attraction member (such as a magnet) is provided on the observation window 9, and the observation window 9 is magnetically fixed to the base 2 by the magnetic attraction member, so that the disassembly and assembly operation is simple, and quick disassembly and assembly can be achieved, thereby improving the efficiency of cleaning and maintenance.

[0090] In other embodiments, the observation window 9 may also be fixed to the base 2 by fasteners such as screws, and the observation window 9 may also be disassembled.

[0091] Optionally, see Figure 1 and Figure 2 The storage bin 1 includes a bin body 11 and a bin cover 12. A receiving chamber 111 is formed in the bin body 11. The bin cover 12 is arranged at the opening of the receiving chamber 111 to ensure that the receiving chamber 111 is relatively airtight to prevent the freeze-dried balls 100 from being contaminated. In addition, the design of the bin cover 12 allows the receiving chamber 111 to be opened, which facilitates the cleaning operation in the receiving chamber 111 and prevents cross contamination of different types of freeze-dried balls 100.

[0092] Further, see Figure 3 and Figure 5 The bin cover 12 is provided with a feed port 121 connected to the containing chamber 111, and the containing chamber 111 can be manually or automatically fed from the feed port 121. The bin cover 12 is also provided with a vent hole 122, which can connect the containing chamber 111 with the outside, ensure the pressure in the containing chamber 111 is stable, and ensure that the freeze-dried balls 100 can fall normally.

[0093] Furthermore, a filter 123 is provided at the air vent 122. On the one hand, the filter 123 can prevent external dust and the like from entering the accommodating chamber 111, thereby preventing the freeze-dried ball 100 from being contaminated. On the other hand, when the second blowing mechanism 7 blows air into the accommodating chamber 111, the filter 123 can prevent the dust in the accommodating chamber 111 from being discharged from the air vent 122, thereby avoiding polluting the external air.

[0094] Exemplarily, the filter element 123 is a medium-efficiency filter cotton, which has the characteristics of high filtering efficiency, low resistance, and excellent fire resistance.
