Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example
[0032] refer to Figure 1-7 The continuous production system of extruded puffed food shown in the figure comprises a raw material supply unit, a mixing and conveying unit, an extrusion and puffing unit, a drying unit and a packaging unit, wherein the raw material supply unit, the mixing and conveying unit, the extrusion and puffing unit, the drying unit and the packaging unit are connected in sequence; the raw material supply unit comprises a grain powder processing component, a grain powder storage tank and a trace element storage tank, and the grain powder processing component comprises a grain raw material bin, a magnetic separator, a hammer mill and a buffer bin which are connected in sequence;
[0033] A screening device is also provided between the magnetic separator and the hammer mill. The screening device is used to separate grains from impurities. After the magnetic separator screens out metal impurities in the grains, the screening device screens the grains again to screen out large and small impurities mixed in the grains. At the same time, the shells in the grains can be cleaned to improve the quality of the puffed food.
[0034] The screening device comprises a chassis 1 and a sieve plate. The chassis 1 is a hollow shell. A feed port 14 communicating with the interior is provided on the top of the chassis 1. The feed port 14 is installed in the middle of the top surface of the chassis 1. A collection frame 13 for collecting debris is also slidably connected to the bottom of the chassis 1. The collection frame 13 is used to collect small particles of debris, and a handle for pulling is also installed on the collection frame 13. A side port for discharging is provided on the left side of the chassis 1. A handle for forming a negative pressure inside the chassis 1 is provided on the right side of the chassis 1. The negative pressure port 12 is connected to the negative pressure device (vacuum cleaner) outside. The husks of grains being screened can be screened and collected by the cooperation of the negative pressure device and the negative pressure port 12. The inside of the chassis 1 is also provided with an inclined sieve plate. The bottom of the sieve plate is hinged to the chassis 1. The front and rear sides of the bottom of the sieve plate are provided with hinge shafts. The sieve plate can rotate around the hinge with the chassis 1 through the hinge shafts. The bottom of the sieve plate corresponds to the position of the side port. The side port is used to discharge the material screened by the sieve plate.
[0035] The sieve plate includes a first sieve plate 5 and a second sieve plate 6, and the side port includes a feed inlet 11 and a discharge port 15. The bottoms of the first sieve plate 5 and the second sieve plate 6 correspond to the positions of the feed inlet 11 and the discharge port 15 respectively. The feed inlet 11 and the discharge port 15 are respectively provided with a feed inlet plate 2 and a discharge plate 3. Through the first sieve plate 5, the feed inlet 11 and the feed inlet 2, large particles of debris in the grains can be screened and discharged; the second sieve plate 6, the discharge port 15 and the discharge plate 3 can screen small particles of debris in the grains, and the small particles of debris pass through the second sieve plate 6 and fall into the collecting frame 13, and the grains enter the hammer crusher through the discharge plate 3 to proceed to the next process.
[0036] The chassis 1 is also provided with a distribution mechanism 7 for driving the sieve plate to rotate around the hinge with the chassis 1. The distribution mechanism 7 can not only distribute the grains to be screened on the sieve plate, but also drive the sieve plate to rotate regularly around the hinge with the chassis 1, so as to produce a bumpy effect on the grains and make the screening more thorough. The distribution mechanism 7 includes a distribution plate 73 and an extrusion wheel 74. A rotating shaft 71 is rotatably connected to the chassis 1. The rotating shaft 71 is rotatably connected to the chassis 1 through a bearing seat. A shaft sleeve 72 is sleeved on the rotating shaft 71. A distribution plate 73 for shifting the grains on the sieve plate is provided on the shaft sleeve 72. The distribution plate 73 An arc-shaped surface is opened on it, and three groups of distribution plates 73 are arranged in a circular array around the axis of the shaft sleeve 72; the rotating shaft 71 is also provided with the extrusion wheel 74 that drives the screen plate to rotate, and the extrusion wheel 74 and the three groups of distribution plates 73 are staggered. The rotating shaft 71 is driven by a motor 75; the screen plate includes a screen frame and a screen mesh. The length dimension of the distribution plate 73 is smaller than the width dimension of the screen mesh. When the distribution plate 73 distributes the grains, the grains in the middle of the screen plate are distributed to both sides of the screen plate to avoid grain accumulation, resulting in poor screening effect. The extrusion wheel 74 corresponds to the position of the screen frame, and the two are slidably connected.
[0037] The interior of the chassis 1 is also provided with a reset mechanism 4 corresponding to the top position of the sieve plate, and the reset mechanism 4 cooperates with the extrusion wheel 74 to work. After the extrusion wheel 74 squeezes the sieve plate downward, the sieve plate is reset by the reset mechanism 4. The reset mechanism 4 includes a mounting plate 41 and a push rod 45. The mounting plate 41 is arranged on the inner wall of the chassis 1, and a guide column 42 is provided on the mounting plate 41. A guide sleeve 44 is slidably connected to the guide column 42. A spring 43 is also provided between the bottom of the guide sleeve 44 and the guide column 42. The top of the guide sleeve 44 is also connected to the push rod 45, and the push rod 45 is slidably connected to the sieve plate.
[0038] The working principle of the utility model is as follows: when in use, the grain raw material bin is controlled to add grains into the magnetic separator. After being screened by the magnetic separator, the grains enter the interior of the chassis 1 through the feed port 14 on the chassis 1, and fall on the first sieve plate 5. Some grains pass through the sieve holes on the first sieve plate 5 and fall on the second sieve plate 6. Most of the grains will roll along the first sieve plate 5 under the component force of gravity and roll toward the distribution plate 73. The motor 75 is controlled to work, drive the rotating shaft 71 to rotate, and drive the extrusion wheel 74 and the shaft sleeve 72 to rotate. The extrusion wheel 74 contacts the sieve frame of the first sieve plate 5 and squeezes the bottom of the first sieve plate 5 to rotate around the hinge with the chassis 1. The top of the first sieve plate 5 squeezes the push rod 45 to move downward, driving the guide sleeve 44 to slide on the guide column 42, and the spring 43 is compressed. When the extrusion wheel 74 is separated from the first sieve plate 5, the first sieve plate 5 is reset under the elastic force of the spring 43. In this cycle, the first sieve plate 5 is regularly moved under the action of the extrusion wheel 74. The vibration of the first sieve plate 5 shakes the grains to prevent the grains from clogging the sieve holes; when the shaft sleeve 72 rotates, the distribution plate 73 is driven to rotate. Since the feed port 14 is located in the middle of the first sieve plate 5, most of the grains are accumulated in the middle. When the distribution plate 73 rotates, the accumulated grains can be moved, and the grains can be moved to the front and rear sides of the first sieve plate 5 in cooperation with the arc surface on the distribution plate 73, so that the grains can be screened more thoroughly. After the screening of the first sieve plate 5, large particles of debris are filtered and discharged from the feed port 11 through the feed guide plate 2; the remaining grains are mixed with small particles of debris. After the screening of the second sieve plate 6, the small particles of debris are screened and fall into the collection frame 13. The grains that meet the standards pass through the discharge plate 3 and are discharged to the hammer mill through the discharge port 15; when the grains fall on the second sieve plate 6 after passing through the first sieve plate 5, the dust and shells mixed in the grains can be pumped through the negative pressure port 12 and an external negative pressure fan, so that the grain screening is more thorough.
