Description

Technical Field

[0001] This invention relates to the field of food processing technology, specifically to a process and equipment for producing mixed grain porridge. Background Technology

[0002] Mixed grain porridge is made from a mixture of various grains such as corn, black rice, Job's tears, black goji berries, and diced apples in a certain proportion. During the processing, the outer husk of each grain is removed, while retaining all the important components and natural nutrients of the grain seeds. The grains are then completely integrated and steamed with water to form mixed grain porridge. It is loved by many for its stomach-soothing and high nutritional value.

[0003] The production process of multigrain porridge involves washing, mixing, sterilization, cooling, and packaging. During the handling process, friction between the grains or impacts from machinery can leave behind impurities such as husks and debris. These impurities can negatively affect the quality of the packaged porridge, and the uneven grain size distribution can also hinder digestion.

[0004] In view of this, in order to overcome the above-mentioned technical problems, the present invention proposes a process and equipment for producing mixed grain porridge rice, which solves the above-mentioned technical problems. Summary of the Invention

[0011] The discharge plate is located between the screen plate and the motor; the discharge plate is obliquely fixed to the inner wall of the material cylinder; the discharge plate is rotatably connected to the rotating rod; the end face of the discharge plate is provided with air holes; the inner diameter of the air holes is smaller than the inner diameter of the grains; the discharge plate is located near the discharge port.

[0012] Air pump No. 1; the air pump No. 1 is fixedly connected between the discharge plate and the bottom of the material cylinder; the output end of the air pump No. 1 is vertically upward;

[0013] Controller; the controller is used to control the automatic operation of the mixed grain porridge production equipment.

[0014] Preferably, the screen discs are inclined; and the inclination angles of two adjacent screen discs are opposite.

[0015] Preferably, a ring is rotatably connected to the inner wall of the material cylinder; the inner wall of the ring is fixedly connected to the outer wall of the screen plate; the ring is made of an elastic material, such as rubber; and the bottom of the material cylinder is connected to the motor via an electric push rod.

[0016] Preferably, a rectangular groove is symmetrically arranged through the lower end of each screen plate inside the material cylinder; one of the rectangular grooves is connected to a second air pump, and the other rectangular groove is connected to a waste discharge pipe.

[0017] Preferably, the lower end of the sieve disc is uniformly provided with arc-shaped pieces around the center of the sieve disc; the connecting line of the two rectangular grooves is eccentric to the center of the sieve disc; the concave surface of the arc-shaped pieces faces the jet direction of the second air pump.

[0018] Preferably, the feed pipe is inclined, and a corrugated pipe is fixedly connected to one end of the feed pipe at the end of the material cylinder; one end of the corrugated pipe abuts against the upper end of the uppermost screen plate.

[0019] Preferably, the feed tube is conical, with the thinner end located inside the material cylinder; an L-shaped rod is fixedly connected to the inner side of one end of the corrugated tube; the other end of the L-shaped rod extends into the feed tube and is fixedly connected to the feed cone; the edge of the feed cone is in contact with the inner wall of the feed tube in the initial state.

[0020] A process for producing mixed grain porridge rice, applicable to mixed grain porridge rice production equipment, comprising the following steps:

[0021] S1: The motor drives the rotating rod to rotate through the output shaft. The rotation of the rotating rod will drive the screen plate to rotate. The screen plate pushes one end of the corrugated pipe to realize the feeding. Select grains with uniform particle size distribution. The grains fall into the screen plate along the corrugated pipe. The screen plate can mix the grains. At the same time, after the grains fall into the screen plate, they are spread out by the centrifugal force generated by the rotation of the screen plate. Impurities are exposed after the grains are spread out. The screen plate will also cause the grains to bounce up and down, so that the grains are slightly lifted on the screen plate, which separates the impurities from the grains.

[0022] S2: Under the action of the rotating rod and the ring, the sieve disc will form a uniform arc-shaped fold around the center of the rotating rod. This fold will further cause the grains to bounce on the sieve disc, and the impurities on the surface of the grains will fall off again. The impurities will be blown away by the airflow generated by the No. 1 air pump in conjunction with the No. 2 air pump and the impurity discharge pipe.

[0023] S3: The cleaned grains continue to spread out along the mesh of the sieve and fall to the next sieve, thus cleaning the impurities mixed in with the grains again.

[0024] S4: The cleaned grains are discharged along the inclined surface of the discharge tray and then fall into the collection box for collection; the grains in the collection box are then sterilized and packaged.

[0025] The beneficial effects of this invention are as follows:

[0026] 1. This invention uses an upward airflow to impact the scattered grains, thereby removing impurities trapped between the grains and improving the quality of the resulting grain porridge. The uniform grain size distribution facilitates digestion and is suitable for infants and children with weak intestinal function and chewing ability.

[0027] 2. In this invention, after the grains fall onto the sieve disc, the sieve disc will cause the grains to rotate in the circumferential direction. In this embodiment, the sieve disc is set at an angle, so that the sieve disc will cause the grains to bounce up and down. This makes the grains slightly bounced on the sieve disc, and the impurities between the grains after bouncing are more easily carried away by the airflow. At the same time, the grains after bouncing are easier to mix, making the mixed grain particles more uniform. It also helps to remove the shells of some grain particles that have not been completely hulled. The impurities trapped in the mesh of the sieve disc become loose under the bouncing action of the sieve disc, making them easier to be carried away by the airflow.

[0028] 3. During the rotation of the rotating rod, the sieve disc will rotate, and the sieve disc will cause the ring sleeve to rotate on the inner wall of the material cylinder. Since the sieve disc is made of elastic material, the sieve disc will form uniform arc-shaped folds around the center of the rotating rod under the action of the rotating rod and the ring sleeve. These folds will further cause the grains to bounce on the sieve disc, and at the same time, the folds will increase the friction with the grains, so that the grains can further achieve the purpose of hulling on the sieve disc. Therefore, this embodiment also has a hulling function, avoiding the impact of incomplete hulling on the quality of the grains. Attached Figure Description

Detailed Implementation

[0038] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0039] like Figures 1 to 7 As shown, the mixed grain porridge production equipment of the present invention includes:

[0040] Material cylinder 1; the upper end of the material cylinder 1 is an air outlet 11, and the upper end is connected to a feed pipe 12; the lower end side wall of the material cylinder 1 is provided with a discharge port 13; the material flowing out of the discharge port 13 is collected by a collection box;

[0041] Motor 2; the motor 2 is connected to the bottom of the material cylinder 1;

[0042] Rotating rod 3; The rotating rod 3 is vertically arranged at the center of the material cylinder 1, and one end is fixedly connected to the output shaft of the motor 2;

[0043] Screen plate 4; the screen plate 4 is fixedly connected to the outer wall of the rotating rod 3; and its edge is in contact with and sealed to the inner wall of the material cylinder 1;

[0044] Discharge plate 5; the discharge plate 5 is located between the screen plate 4 and the motor 2; the discharge plate 5 is obliquely fixed to the inner wall of the material cylinder 1; the discharge plate 5 is rotatably connected to the rotating rod 3; the end face of the discharge plate 5 is provided with an air hole 51; the inner diameter of the air hole 51 is smaller than the inner diameter of the grain; the discharge plate 5 is located close to the discharge port 13.

[0045] Air pump 6; the air pump 6 is fixedly connected between the discharge plate 5 and the bottom of the material cylinder 1; the output end of the air pump 6 is vertically upward;

[0046] Controller; the controller is used to control the automatic operation of the mixed grain porridge production equipment;

[0047] During operation, the rice grains may rub against each other or be impacted by the machine, leaving behind some husks, debris, and other impurities that are not properly cleaned. This can affect the quality of the packaged mixed grain rice porridge due to these impurities.

[0048] Therefore, in this invention, after the grains are washed, dried, and shelled, they enter the feed cylinder 1 through the feed pipe 12. The controller controls the operation of the first air pump 6 and the motor 2. The first air pump 6 sprays gas, which passes through the air holes 51 on the discharge plate 5, the sieve plate 4, and finally sprays out through the air outlet 11. The motor 2 drives the rotating rod 3 to rotate through the output shaft. The rotation of the rotating rod 3 drives the sieve plate 4 to rotate. The sieve plate 4 can mix the grains. At the same time, after the grains fall onto the sieve plate 4, the centrifugal force generated by the rotation of the sieve plate 4 spreads them out. Impurities are exposed after the grains are spread out and then carried away by the airflow. The cleaned grains continue to fall along the mesh of the sieve 4 to the next sieve 4. As the grains fall in a scattered manner, the airflow can increase the contact area with the grains, making it impossible for impurities to escape and thus they are washed away. As a result, a large amount of impurities are removed from the grains that finally fall onto the discharge 5. The grains are then cleaned again by the air in the upward impact of the air holes 51 in the discharge 5. They are then discharged along the inclined surface of the discharge 5 through the discharge port 13 and finally fall into the collection box for collection. The grains in the collection box are then sterilized and packaged.

[0049] This invention uses an upward airflow to impact the scattered grains, thereby carrying away impurities trapped between the grains and improving the quality of the resulting grain porridge.

[0050] In one embodiment of the present invention, the sieve disc 4 is inclined; and the inclination angles of two adjacent sieve discs 4 are opposite.

[0051] During operation, after the grains fall onto the sieve plate 4, the sieve plate 4 will cause the grains to rotate in the circumferential direction. In this embodiment, the sieve plate 4 is set at an angle, so that the sieve plate 4 will cause the grains to bounce up and down. This makes the grains slightly bounced on the sieve plate 4, and the impurities between the grains after being bounced are more easily carried away by the airflow. At the same time, the grains after being bounced are easier to mix, making the mixed grain particles more uniform. It also helps to remove the shells of some grain particles that have not been completely shelled. The impurities trapped in the mesh of the sieve plate 4 become loose under the bouncing action of the sieve plate 4, making them easier to be carried away by the airflow.

[0052] In one embodiment of the present invention, a ring sleeve 14 is rotatably connected to the inner wall of the material cylinder 1; the inner wall of the ring sleeve 14 is fixedly connected to the outer wall of the screen plate 4; the ring sleeve 14 is made of an elastic material, such as rubber; the bottom of the material cylinder 1 is connected to the motor 2 through an electric push rod 15.

[0053] During operation, the rotating rod 3 drives the sieve disc 4 to rotate, which in turn drives the ring 14 to rotate on the inner wall of the material cylinder 1. Since the sieve disc 4 is made of elastic material, it forms uniform arc-shaped folds around the center of the rotating rod 3 under the action of the rotating rod 3 and the ring 14. These folds further agitate the grains on the sieve disc 4 and increase the friction with the grains, thus further achieving the purpose of hulling. This embodiment also has a hulling function, preventing incomplete hulling from affecting the quality of the grains. The mesh on the sieve disc 4 also deforms after the folds are formed, changing the air outlet direction. This allows the airflow from the mesh to further clean the surrounding grains from multiple directions. Simultaneously, after the sieve disc 4 has been working for a period of time, the controller extends the electric push rod 15, causing the rotating rod 3 to move upwards under the action of the electric push rod 15. This causes the rotating rod 3 to move the center of the sieve disc 4... The upward pulling of the screen plate 4 causes the grains at the top of the screen plate 4 to gather at the edge of the screen plate 4. The center of the screen plate 4, which is bulging out, is unobstructed by grains, allowing air to pass through more easily. This washes away the impurities trapped in the mesh of the screen plate 4. The mesh of the screen plate 4 is stretched and deformed into a flat shape, causing the air to vibrate as it passes through the flat mesh. This principle is similar to how pursed lips vibrate under the action of airflow. Impurities in the mesh are more easily dislodged under the vibration, thus better clearing the center of the screen plate 4. Then, the controller controls the electric push rod 15 to shorten, causing the center of the screen plate 4 to be pulled downward and concave. This allows the grains to fall from the edge into the center of the screen plate 4, ensuring that there are no grains obstructing the edge of the screen plate 4 and that the airflow can pass through smoothly. Following the same principle, the mesh on the edge of the screen plate 4 also vibrates after the airflow passes through, achieving better clearing. The stretching and deformation of the mesh on the screen plate 4 loosens the impurities in the mesh, making it easier for the airflow to carry them away.

[0054] In one embodiment of the present invention, rectangular grooves 16 are symmetrically arranged through the lower end of each screen plate 4 inside the material cylinder 1; one of the rectangular grooves 16 is connected to a second air pump 17, and the other rectangular groove 16 is connected to a waste discharge pipe 18.

[0055] During operation, as the impurities trapped between the grains on the sieve plate 4 move upward with the airflow generated by the first air pump 6, the second air pump 17 sprays airflow through the rectangular groove 16, blowing the impurities to the vicinity of another rectangular groove 16. Then, the external suction device sucks air into the discharge pipe 18, creating a negative pressure in the discharge pipe 18. This causes the impurities around the other rectangular groove 16 to be drawn into the discharge pipe 18 with the airflow, thus ensuring the cleanliness of the airflow passing through the sieve plate 4 as much as possible and reducing the secondary contamination of the grains that have just fallen onto the sieve plate 4 by the impurities carried by the airflow. This makes the design of the invention more reasonable.

[0056] In one embodiment of the present invention, an arc-shaped piece 41 is uniformly arranged around the center of the sieve disc 4 at the lower end of the sieve disc 4; the connecting line of the two rectangular grooves 16 is eccentric to the center of the sieve disc 4; the concave surface of the arc-shaped piece 41 faces the jet direction of the second air pump 17; during operation, as the rotating rod 3 pulls the sieve disc 4 downward, the sieve disc 4 causes the arc-shaped piece 41 to bulge downward. The gas generated by the second air pump 17 impacts the arc-shaped piece 41 on the bulging sieve disc 4. After being impacted by the gas, the arc-shaped piece 41 generates a rotational force, thereby driving the fixed rotating rod 3 to rotate, thus providing kinetic energy for the rotation of the sieve disc 4. The arc-shaped piece 41 is impacted by the gas generated by the second air pump 17, causing the sieve disc 4 to deform. After the arc-shaped piece 41 moves away from the second air pump 17, it returns to its original position, thereby causing the arc-shaped piece 41 to drive the sieve disc 4 to deform back and forth. This facilitates the unblocking of the mesh at the deformed part of the sieve disc 4 and increases the friction between the deformed part of the sieve disc 4 and the grain, making it easier to remove the husk.

[0057] In one embodiment of the present invention, the feed pipe 12 is inclined and the corrugated pipe 7 is fixedly connected to one end of the feed cylinder 1. One end of the corrugated pipe 7 abuts against the upper end of the uppermost sieve plate 4. During operation, due to its special structure, one end of the corrugated pipe 7 is compressed along the axial direction of the corrugated pipe 7 and folded in a regular pattern after being squeezed. In this embodiment, the other end of the corrugated pipe 7 is in contact with the upper end of the sieve plate 4, so that the other end of the corrugated pipe 7 is always in contact with the sieve plate 4 during the vertical position change of the sieve plate 4. This ensures that the grains input by the feed pipe 12 will fall onto the sieve plate 4 through the guidance of the corrugated pipe 7, avoiding the situation where the grains are broken when directly poured onto the sieve plate 4. Furthermore, after being squeezed back and forth, the corrugated pipe 7 will regularly contract-stretch-contract, causing the grains to peristalse inside the corrugated pipe 7, which facilitates feeding and achieves frictional dehulling of the grain particles.

[0058] In one embodiment of the present invention, the feed pipe 12 is conical, with the thinner end located inside the material cylinder 1; an L-shaped rod 71 is fixedly connected to the inner side of one end of the corrugated pipe 7; the other end of the L-shaped rod 71 extends into the feed pipe 12 and is fixedly connected to the feed cone 72; the edge of the feed cone 72 is in contact with the inner wall of the feed pipe 12 in the initial state; during operation, as the screen plate 4 squeezes and releases one end of the corrugated pipe 7, the corrugated pipe 7 will drive the L-shaped rod 71 to move back and forth along the axial direction of the feed pipe 12, and as the L-shaped rod 71 drives the feed cone 72 away from the screen plate 4, the feed cone 7... 2. The grains are squeezed apart and a gap is formed between them and the feed pipe 12. The grains will pass over the feed cone 72 under the action of gravity and then move along the corrugated pipe 7 into the screen plate 4. As the L-shaped rod 71 drives the feed cone 72 to approach the screen plate 4, the gap between the feed cone 72 and the feed pipe 12 decreases until it is closed, so as to achieve the purpose of intermittent feeding to the feed pipe 12. Furthermore, by setting the diameter of the feed pipe 12 according to the corresponding ratio of the grain porridge rice, this embodiment can automatically control the feeding process. That is, when the rotating rod 3 moves down and pulls the screen plate 4, the screen plate 4 and the corrugated pipe 7 cannot contact each other, thus pausing the feeding.

[0059] A process for producing mixed grain porridge rice, applicable to the aforementioned mixed grain porridge rice production equipment, comprising the following steps:

[0060] S1: Motor 2 drives the rotating rod 3 to rotate via the output shaft. The rotation of the rotating rod 3 drives the screen plate 4 to rotate. The screen plate 4 pushes one end of the corrugated pipe 7 to feed the grains. Grains with uniform particle size distribution are selected. The grains fall onto the screen plate 4 along the corrugated pipe 7. The screen plate 4 can mix the grains. At the same time, after the grains fall onto the screen plate 4, the centrifugal force generated by the rotation of the screen plate 4 causes the grains to spread out. Impurities are exposed after the grains are spread out. The screen plate 4 also causes the grains to bounce up and down, so that the grains are slightly lifted on the screen plate 4, which separates the impurities from the grains. The selection of grains with uniform particle size distribution is conducive to digestion and is suitable for infants and children whose intestinal function and chewing ability are still weak.

[0061] S2: Under the action of the rotating rod 3 and the ring 14, the sieve plate 4 will form a uniform arc-shaped fold around the center of the rotating rod 3. The fold will further cause the grains to bounce on the sieve plate 4, and the impurities on the surface of the grains will fall off again. The impurities will be blown away by the airflow generated by the No. 1 air pump 6 in conjunction with the No. 2 air pump 17 and the impurity discharge pipe 18.

[0062] S3: The cleaned grains continue to spread out along the mesh on the sieve plate 4 and fall to the next sieve plate 4, so as to clean the impurities mixed in the grains again.

[0063] S4: The cleaned grains are discharged along the inclined surface of the discharge tray 5 and the discharge port 13, and finally fall into the collection box for collection; then the grains in the collection box are sterilized and packaged.

[0064] The specific workflow is as follows:

[0065] In this invention, after the grains are washed, dried, and shelled, they enter the feed cylinder 1 through the feed pipe 12. The controller controls the operation of the first air pump 6 and the motor 2. The first air pump 6 sprays gas, which passes through the air holes 51 on the discharge plate 5, the sieve plate 4, and finally exits through the air outlet 11. The motor 2 drives the rotating rod 3 to rotate through the output shaft. The rotation of the rotating rod 3 drives the sieve plate 4 to rotate. The sieve plate 4 mixes the grains and, after falling onto the sieve plate 4, the grains are spread out by the centrifugal force generated by the rotation of the sieve plate 4. Impurities are exposed after the grains are spread out and then carried away by the airflow. After being cleaned, the grains continue to fall along the mesh of the sieve 4 to the next sieve 4. During the process of falling into the next sieve 4, since the grains fall in a scattered manner, the airflow can increase the contact area with the grains, making it impossible for impurities to hide and being washed away. In this way, a large amount of impurities are removed from the grains that finally fall onto the discharge sieve 5. Then, the grains are cleaned again by the air in the upward impact of the air holes 51 in the discharge sieve 5. They are then discharged along the inclined surface of the discharge sieve 5 and the discharge port 13, and finally fall into the collection box for collection. The grains in the collection box are then sterilized and packaged.

[0066] In this embodiment, after the grains fall onto the sieve disc 4, the sieve disc 4 will cause the grains to rotate circumferentially. In this embodiment, the sieve disc 4 is tilted, causing the grains to bounce up and down, resulting in the grains being slightly lifted on the sieve disc 4. Impurities among the lifted grains are more easily carried away by the airflow. Simultaneously, the lifted grains are easier to mix, resulting in more uniform mixed grain particles. Furthermore, some grain particles that are not fully hulled are hulled. Impurities trapped in the mesh of the sieve disc 4 become loose under the bouncing action of the sieve disc 4, making them easier to be carried away by the airflow. During the rotation of the rotating rod 3, the sieve disc 4 rotates, causing the ring 14 to rotate on the inner wall of the material cylinder 1. Since the sieve disc 4 is made of elastic material, the sieve disc... Under the action of the rotating rod 3 and the ring 14, uniform arc-shaped folds will form around the center of the rotating rod 3. These folds will further agitate the grains on the sieve disc 4, and at the same time, they will increase the friction with the grains, so that the grains can be further dehulled on the sieve disc 4. This embodiment also has a dehulling function, which avoids the grains' quality being affected by incomplete dehulling. The mesh on the sieve disc 4 will also deform after the folds are formed, so that the air outlet direction of the mesh on the sieve disc 4 will change after deformation. This will allow the airflow from the mesh to further blow on the surrounding grains in multiple directions, and further achieve cleaning. At the same time, after the sieve disc 4 has been working for a period of time, the controller will control the electric push rod 15 to extend, so that the rotating rod 3 will be pushed by the electric push rod 15. The rod 15 moves upward, causing the rotating rod 3 to pull the center of the sieve disc 4 upward and bulge it. This causes the grains on the upper part of the sieve disc 4 to gather at the edge of the sieve disc 4, while the bulging center of the sieve disc 4 is unobstructed by grains, allowing gas to pass through more easily. This washes away the impurities trapped in the mesh of the sieve disc 4. The mesh of the sieve disc 4 is deformed into a flat shape after being pulled, causing the gas to vibrate after passing through the flat mesh. This principle is similar to how pursed lips vibrate under the action of airflow, making it easier for impurities in the mesh to fall off under the vibration, thus better clearing the center of the sieve disc 4. Subsequently, the controller controls the electric push rod 15 to shorten, causing the center of the sieve disc 4 to be pulled downward and concave, thus allowing the grains to flow from the edge. The impurities fall into the center of the sieve plate 4, ensuring that there are no grains obstructing the edge of the sieve plate 4, allowing the airflow to pass smoothly and achieve unblocking. Following the same principle, the mesh on the edge of the sieve plate 4 will also vibrate after the airflow passes through, achieving better unblocking. The mesh on the sieve plate 4 is stretched and deformed, causing the impurities inside the mesh to loosen, making it easier for the airflow to carry away the impurities. As the impurities mixed between the grains on the sieve plate 4 move upward with the airflow generated by the first air pump 6, the second air pump 17 will spray airflow through the rectangular groove 16, thereby blowing the impurities to the vicinity of another rectangular groove 16. Then, the external suction device will suck air into the discharge pipe 18, creating a negative pressure in the discharge pipe 18, thereby causing the impurities around the other rectangular groove 16 to be sucked into the discharge pipe 18 with the airflow.During the downward pulling of the screen disk 4 by the rotating rod 3, the screen disk 4 causes the arc-shaped piece 41 to bulge downwards. The gas generated by the second air pump 17 impacts the arc-shaped piece 41 on the bulging screen disk 4. The arc-shaped piece 41 generates a rotational force after being impacted by the gas, thereby driving the fixed rotating rod 3 to rotate, thus providing kinetic energy for the rotation of the screen disk 4. The arc-shaped piece 41 is impacted by the gas generated by the second air pump 17, causing the screen disk 4 to deform. After the arc-shaped piece 41 moves away from the second air pump 17, it returns to its original position, thus causing the arc-shaped piece 41 to drive the screen disk 4 to deform back and forth. Due to its special structure, one end of the bellows 7 is compressed along the axial direction of the bellows 7 and folded in a regular pattern after being squeezed. In this embodiment, the other end of the bellows 7 is in contact with the upper end of the screen disk 4, causing the screen disk 4 to change position vertically. During the processing, the other end of the corrugated pipe 7 remains in contact with the screen plate 4, ensuring that the grains fed into the feed pipe 12 are guided by the corrugated pipe 7 onto the screen plate 4, preventing the grains from being broken when poured directly onto the screen plate 4. Furthermore, the corrugated pipe 7 contracts, stretches, and contracts rhythmically after being squeezed back and forth. As the screen plate 4 squeezes and releases one end of the corrugated pipe 7, the corrugated pipe 7 drives the L-shaped rod 71 to move back and forth along the axial direction of the feed pipe 12. As the L-shaped rod 71 moves the feed cone 72 away from the screen plate 4, the feed cone 72 pushes aside the grains and creates a gap with the feed pipe 12. The grains, under gravity, pass over the feed cone 72 and then move along the corrugated pipe 7 into the screen plate 4. Conversely, as the L-shaped rod 71 moves the feed cone 72 closer to the screen plate 4, the gap between the feed cone 72 and the feed pipe 12 decreases until it closes.
