Description

Technical Field

[0001] This invention relates to the field of fermented grain conveying technology, and more specifically to a conveying method that reduces the contact between fermented grain and air. Background Technology

[0002] In the brewing industry, there are two main types of materials transported: the mash that has been cooked and then enters the fermentation tank for fermentation; and the distillate that has been fermented and then enters the cooking zone for distillation. Both of these are referred to as mash. As the number of fermentation and distillation cycles increases, the agglomeration effect of the mash gradually increases, the porosity gradually decreases, and the mash is prone to clump together. At the same time, the viscosity of the mash is further increased due to the gelatinization of starch in the mash.

[0003] Currently, traditional conveying devices for fermented grains all have some drawbacks. These drawbacks are specifically described below:

[0004] The existing methods used by wineries for transporting mash include overhead cranes with buckets, screw conveyors, plate chain conveyors, and belt conveyors. These traditional equipment tend to increase the contact rate between the mash and air during transport, which can lead to the mash being contaminated by impurities and other harmful substances in the air, affecting its later efficacy and use.

[0005] Furthermore, the aforementioned traditional fermented mash conveying equipment cannot address the problem of fermented mash clumping during actual use. How to maintain the looseness of fermented mash during conveying and prevent clumping has become another urgent technical problem to be solved in this field. Screw conveyors can disperse and convey fermented mash to a certain extent, but they are prone to damaging the fermented mash during use, causing excessive loss of components and efficacy during the conveying process.

[0006] Therefore, the conveying method for reducing the contact between the fermented mash and air proposed in this application is urgently needed in the field. Summary of the Invention

[0007] In view of this, the purpose of the present invention is to provide a conveying method that reduces the contact between the fermented mash and air, so as to solve the problem that the fermented mash is easily exposed to air when conveying it in the conventional fermented mash conveying device, and further solve the problem that the fermented mash sticks together when conveying it in the conventional fermented mash conveying device.

[0008] This invention is achieved through the following technical solution:

[0009] Methods for reducing the contact between the fermented mash and air include using a fermented mash conveying device to convey the fermented mash;

[0010] The fermented grain conveying device specifically includes a frame, a feeding mechanism, a conveying mechanism, and a receiving mechanism;

[0011] The feeding mechanism includes a feeding funnel and a distributing hopper integrally formed with the frame. The distributing hopper has a hollow interior. The bottom opening of the feeding funnel communicates with the interior of the distributing hopper. A motor is installed on the frame. A roller is installed inside the distributing hopper. The motor drives the roller to rotate through a transmission mechanism. At least three blades are spaced apart on the roller. The blades extend along the length of the roller. Two adjacent blades form a conveying unit for the mash. When two adjacent blades rotate with the roller to the top of the distributing hopper, the two blades correspond to the two sides of the bottom opening of the feeding funnel, achieving a temporary sealing effect.

[0012] The roller shaft is symmetrically provided with baffles at both ends. The baffles are located inside the material distribution barrel. The blades are located between the two baffles. At least three ventilation holes are provided on one of the baffles. Each ventilation hole corresponds to a conveying unit. An air inlet is provided on one side of the material distribution barrel and extends into the interior of the material distribution barrel. When the blades rotate with the roller shaft, they rotate to the conveying unit located at the lower part of the material distribution barrel. The ventilation hole corresponding to the blades is opposite to the air inlet. The end of the air inlet that is away from the material distribution barrel is connected to an air conveying mechanism.

[0013] The conveying mechanism includes a conveying pipe connected to the bottom of the dispensing hopper. The conveying pipe is a hollow structure with open ends. One end of the conveying pipe is connected to a power mechanism. The conveying mechanism also includes a Venturi tube connected to the other end of the conveying pipe.

[0014] The receiving mechanism includes a separation chamber, which is connected to a venturi tube via a connecting pipe. The separation chamber is a hollow structure with an open bottom.

[0015] The conveying method steps are as follows:

[0016] 1) Primary conveying of fermented mash;

[0017] I. Start the motor, and the mash enters the inside of the distribution tank through the top of the feed funnel;

[0018] II. Each conveying unit transports a limited amount of mash during the conveying process. The rollers rotate, causing the mash to move within the individual conveying unit, preventing it from clumping together.

[0019] III. Rotate to the lower part of the conveying unit inside the distribution bucket, with the air inlet and the vent facing each other. Air enters through the air inlet and is further dispersed through the vent to prevent the mash in the conveying unit from clumping together and sticking to the blades.

[0020] 2) Secondary conveying of fermented mash;

[0021] I. The mash continues to be transported, flowing into the interior of the conveying pipe through the distribution bucket. The power mechanism then further transports the mash to the Venturi tube. The flow of mash inside the Venturi tube creates a speed difference, which further improves the looseness of the mash and prevents it from sticking together.

[0022] II. The mash flows inside the Venturi tube to the connecting tube, and is then transported to the separation chamber via the connecting tube;

[0023] In step 2, the separation chamber has a receiving pipe integrally installed at its top edge. The receiving pipe is connected to the connecting pipe, so that the mash enters the separation chamber through the connecting pipe and the receiving pipe.

[0024] Furthermore, both ends of the roller shaft pass through the distribution bucket and extend to both ends of the distribution bucket. Bearing seats are provided at both ends of the distribution bucket, and both ends of the roller shaft are connected to the inner rings of the bearing seats.

[0025] Furthermore, the blades are provided with a sealing plate in a detachable manner along their length, located at the edge opposite to the roller shaft.

[0026] Furthermore, a through hole is provided through the sealing plate, and a clamping member for clamping the blade is provided inside the through hole;

[0027] The clamping member includes a connecting rod passing through a through hole. One end of the connecting rod is provided with an extension extending in the direction of the blade. The extension is provided with a threaded hole corresponding to the blade, and a threaded bolt is threaded into the threaded hole.

[0028] Furthermore, at least three embedding slots are provided on the opposite side of the two baffles, and the two ends of the blade extend to the inside of the embedding slots.

[0029] Furthermore, the power mechanism is a Roots blower, and the outlet end of the Roots blower is connected to the material conveying pipe.

[0030] Furthermore, the air delivery mechanism is an air compressor, and the air outlet of the air compressor is connected to the air inlet.

[0031] Furthermore, the top of the separation chamber is equipped with an air outlet pipe that communicates with its interior.

[0032] Furthermore, the transmission mechanism includes a power transmission belt connected to the output shaft of the motor. The power transmission belt wraps around one end of the roller shaft. When the shaft rotates, the power transmission belt drives the roller shaft to rotate.

[0033] Furthermore, the transmission mechanism includes a transmission gear disposed at one end of the roller shaft and a drive gear disposed on the motor shaft. The transmission mechanism also includes a chain disposed on the drive gear and the transmission gear.

[0034] The beneficial effects of this invention are as follows:

[0035] 1. This conveying method, which reduces the contact between the mash and air, utilizes a frame, feeding hopper, distribution bin, motor, transmission mechanism, rollers, blades, conveying unit, baffles, vents, air inlets, conveying pipes, venturi pipes, separation bins, connecting pipes, and receiving pipes. During the conveying of the mash, it falls through the feeding hopper into the distribution bin. At this point, the conveying unit achieves the initial conveying of a limited quantity of mash, preventing excessive accumulation in one place. When the conveying unit is located at the bottom of the distribution bin, the air inlet is opposite the vent. Under the action of the air conveying mechanism, the air inlet further loosens the mash, preventing it from becoming brittle. The mash is piled up into clumps, further preventing it from sticking to the blade surface. At this time, the mash is inside the conveying pipe. Under the action of the air conveying mechanism, the mash is transported to the Venturi tube. Utilizing the Venturi tube, some of the mash generates a rate difference, further preventing the mash from clumping together. It can be seen that the technical solution of this application cleverly utilizes different conveying units to partially and partially convey the mash, avoiding excessive clumping in one place. The cooperation between the air inlet and the vent further prevents the mash from sticking to the blade surface. Through this dual loose conveying method, the looseness of the mash can be greatly improved, preventing it from clumping together and sticking to the blade.

[0036] 2. This conveying method that reduces the contact between the mash and air uses a separation chamber, a receiving pipe and a connecting pipe. When the mash enters the receiving pipe through the connecting pipe, since the receiving pipe is located at the top edge of the separation chamber, the mash will use inertia to make centrifugal rotation inside the separation chamber, thereby loosening the mash again and preventing it from sticking together.

[0037] 3. This conveying method that reduces the contact between the mash and air involves transporting the mash within a closed pipe system (feeding pipe, venturi pipe, receiving pipe, and connecting pipe, etc.) during the conveying process, which can effectively reduce the contact rate between the mash and air.

[0038] 4. This conveying method, which reduces the contact between the mash and air, allows the blades to briefly seal the bottom opening of the feed hopper during the rotation of the roller. When the next conveying unit moves relative to the feed hopper, the blades of that conveying unit can also briefly seal the feed hopper. This prevents gas from flowing upward through the distribution bucket and affecting the conveying efficiency of the mash when the mash is conveyed with gas assistance inside the conveying pipe.

[0039] Other advantages, objectives, and features of the invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination, or may be learned from practice of the invention. The objectives and other advantages of the invention can be realized and obtained through the following description. Attached Figure Description

[0058] Please see Figure 1-11The present invention provides a technical solution: a conveying method for reducing the contact between fermented mash and air, including conveying the fermented mash using a fermented mash conveying device;

[0059] The fermented mash conveying device specifically includes a frame 1, a feeding mechanism 2, a conveying mechanism 10, and a receiving mechanism 11;

[0060] The feeding mechanism 2 includes a feeding funnel 201 and a distributing bin 202 integrally formed with the frame 1. The distributing bin 202 has a hollow structure inside. The bottom opening of the feeding funnel 201 communicates with the inside of the distributing bin 202. A motor 3 is installed on the frame. A roller 4 is installed inside the distributing bin 202. The motor 3 drives the roller 4 to rotate through a transmission mechanism. At least three blades 5 are spaced apart on the roller 4. The blades 5 extend along the length of the roller 4. Two adjacent blades 5 form a conveying unit 6 of the mash. When two adjacent blades 5 rotate with the roller 4 to the top of the distributing bin 202, the two blades 5 correspond to the two sides of the bottom opening of the feeding funnel 201, which achieves a temporary sealing effect.

[0061] The power mechanism is a Roots blower, the air outlet of the Roots blower is connected to the material conveying pipe 1001, and the air conveying mechanism is an air compressor, the air outlet of the air compressor is connected to the air inlet 9.

[0062] Roots blowers can inject air into the conveying pipe, which can effectively help transport the mash to the Venturi tube and subsequent equipment.

[0063] Air compressors can inject air into the air inlet, which helps to loosen the mash inside the conveying unit, prevent it from clumping together, and further prevent the mash from sticking to the blade surface.

[0064] The Roots blower and air compressor used in this application can filter toxic and harmful substances in the gas before it is delivered to the interior of the device. The model of the Roots blower and air compressor can be SR80H.

[0065] The mash first enters the mash conveying device through the feeding funnel. At the same time, the motor starts and drives the roller to rotate through the transmission mechanism. When the mash enters the distribution tank through the feeding funnel, different conveying units can receive a certain amount of mash. Under the action of the roller, the conveying unit continues to rotate.

[0066] As the motor operates, the roller continues to rotate, and the conveying units rotate sequentially to the position opposite to the air inlet. At this time, the air delivery mechanism is working normally, and gas can be injected into the different conveying units sequentially through the air inlet to loosen the mash in the conveying unit and prevent it from sticking to the surface of the blades and the dispensing bucket.

[0067] As the blades and conveying unit continue to rotate, when the conveying unit is located below the inside of the distribution bucket, the mash falls directly into the inside of the conveying pipe. At this time, under the action of the power mechanism, the mash inside the conveying pipe is conveyed to the next stage, which can be the fermentation stage of the mash. A connecting pipe is connected to the conveying pipe to directly convey the mash to the fermentation tank.

[0068] The roller shaft 4 is symmetrically provided with baffles 7 at both ends. The baffles are located inside the material distribution barrel. It should be noted that the baffles rotate together with the roller shaft. The blades 5 are located between the two baffles 7. At least three ventilation holes 8 are provided on one of the baffles 7. Each ventilation hole 8 corresponds to a conveying unit 6. An air inlet 9 is provided on one side of the material distribution barrel 202 and extends into the interior of the material distribution barrel 202. When the blades 5 rotate with the roller shaft 4 and rotate to the conveying unit 6 at the lower part of the material distribution barrel 202, the ventilation hole 8 corresponding to it is opposite to the air inlet 9. The end of the air inlet 9 away from the material distribution barrel 202 is connected to an air conveying mechanism.

[0069] As the conveying unit continues to rotate to the lower part of the distribution bucket, the air conveying mechanism continues to work, injecting airflow through the air inlet. When the roller rotates, the ventilation port of the conveying unit located below is exactly opposite to the position of the air inlet, allowing the airflow to flow into the interior of the conveying unit to further loosen the mash and prevent it from sticking to the surface of the blades and being unable to continue conveying. At this time, the loosened mash can fall directly into the interior of the conveying pipe by its own gravity.

[0070] The conveying mechanism 10 includes a conveying pipe 1001 connected to the bottom of the distribution tank 202. The conveying pipe 1001 is a hollow structure with open ends. One end of the conveying pipe 1001 is connected to the power mechanism. The conveying mechanism 10 also includes a venturi tube 1002 connected to the other end of the conveying pipe 1001. When the mash continues to flow downward inside the distribution tank to the inside of the conveying pipe, the conveying mechanism works at the same time. It generates air force to transport the mash from the inside of the conveying pipe to the inside of the venturi tube. Utilizing the special structure of the venturi tube, a rate difference occurs in the mash inside the venturi tube (some mash is conveyed faster and some mash is conveyed slower), so that the mash can be further conveyed in batches. At this time, the looseness of the mash can be further improved, and it can be prevented from sticking together.

[0071] The receiving mechanism 11 includes a separation chamber 1101, which is connected to the Venturi tube 1002 via a connecting pipe 13. The separation chamber 1101 is a hollow structure with an open bottom. The mash enters the interior of the connecting pipe through the Venturi tube and eventually flows into the interior of the separation chamber. The bottom of the separation chamber is open and directly faces the fermentation tank. The loosened mash can flow directly into the fermentation tank from the interior of the separation chamber.

[0072] The conveying method steps are as follows:

[0073] 1) Primary conveying of fermented mash;

[0074] I. Start motor 3, and the mash enters the inside of the distribution tank 202 through the top of the feed funnel 201;

[0075] II. Each conveying unit 6 transports a limited amount of mash during the conveying process. The roller 4 rotates, causing the mash to move within the individual conveying unit 6, preventing it from clumping together.

[0076] III. Rotate to the lower conveying unit 6 inside the distribution bucket 202. The air inlet 9 and the ventilation port 8 are opposite each other. Air enters through the air inlet 9 and blows the mash in the conveying unit 6 further through the ventilation port 8 to prevent it from clumping together and sticking to the blades 5. Due to the continuous rotation of the roller, the ventilation ports opened on the baffle are opposite to the air inlet in turn according to the different loosening units they correspond to, thereby loosening the mash inside each conveying unit and preventing it from clumping together.

[0077] 2) Secondary conveying of fermented mash;

[0078] I. The mash continues to be transported and flows into the interior of the conveying pipe 1001 through the distribution bucket 202. Through the power mechanism, the mash is further conveyed to the venturi tube 1002. The mash flowing inside the venturi tube 1002 has a speed difference, which further improves the looseness of the mash and prevents it from sticking together.

[0079] II. The mash flows inside the Venturi tube 1002 to the connecting tube 13, and is then transported to the separation chamber 1101 via the connecting tube 13;

[0080] In step 2, the separation chamber 1101 has a receiving pipe 12 integrally installed on its top edge. The receiving pipe is connected to the inside of the separation chamber and the receiving pipe 12 is connected to the connecting pipe 13, so that the mash enters the separation chamber 1101 through the connecting pipe 13 and the receiving pipe 12. The receiving pipe is further installed here and is located on the top edge of the separation chamber. When the mash enters the receiving pipe through the connecting pipe, due to the special design position of the receiving pipe, the mash enters the separation chamber in a centrifugal rotation. The mash continues to rotate inside the separation chamber until it finally falls down into the fermentation tank through the bottom opening of the separation chamber due to its own gravity. This achieves the final loosening effect of the mash, and the conveying of the mash is thus closed-loop.

[0081] The connecting tube is currently the food-grade pressure-resistant hose in this field.

[0082] In this embodiment: the two ends of the roller shaft 4 pass through the distribution bucket 202 and extend to the two ends of the distribution bucket 202. The two ends of the distribution bucket 202 are provided with bearing seats 21, and the two ends of the roller shaft 4 are connected to the bearing inner ring of the bearing seat 21.

[0083] Here, the roller is further extended to the outside of the dispensing hopper. Supported by the bearing housing, the roller is supported while also allowing it to rotate effectively.

[0084] In this embodiment: the blade 5 is away from the edge of the roller shaft 4, and a sealing plate 14 is provided in a detachable manner along its length direction;

[0085] During the rotation of the roller, the blades can be positioned directly opposite the bottom opening of the feed hopper, and the sealing plate can be positioned further close to the edge of the bottom opening of the feed hopper to improve the temporary sealing of the conveying unit.

[0086] In this embodiment: a through hole 15 is provided through the sealing plate 14, and a clamping member for clamping the blade 5 is provided inside the through hole 15;

[0087] The clamping component includes a connecting rod 16 passing through the through hole 15. One end of the connecting rod 16 is provided with an extension 18 extending in the direction of the blade 5. The extension 18 is provided with a threaded hole corresponding to the blade 5, and a threaded bolt 17 is threadedly tightened on the threaded hole.

[0088] The purpose of this additional clamping element is to allow for immediate replacement of the sealing plate should it be damaged.

[0089] Rotate the threaded bolt to remove it from the threaded hole, and then pull out the connecting rod and extension to separate the sealing plate from the blade.

[0090] In this embodiment: at least three embedding grooves 20 are provided on the opposite side of the two baffles 7, and the two ends of the blade 5 extend to the inside of the embedding grooves 20;

[0091] An embedding groove is further provided here, so that when the roller rotates, the blade can be precisely locked inside the embedding groove. At this time, when the blade and the baffle rotate with the roller, the overall tightness is higher, and the relative stability is better, which is conducive to the long-term effective use of this device.

[0092] In this embodiment, the top of the separation chamber 1101 is provided with an air outlet pipe 19 that communicates with its interior. When the mash enters the interior of the separation chamber, the gas accompanying the mash during the transportation process can be discharged to the outside of the separation chamber through the air outlet pipe.

[0093] In this embodiment, the transmission mechanism includes a power transmission belt connected to the output shaft of the motor 3. The power transmission belt wraps around one end of the roller shaft 4. When the shaft rotates, the power transmission belt drives the roller shaft 4 to rotate. Here, the motor is driven by a belt wound around its shaft and then wrapping the belt around the roller shaft. When the motor works and the shaft rotates, the transmission is carried out by belt drive. This embodiment is easy to operate, and the belt is inexpensive. When the belt is damaged, it can be easily replaced.

[0094] In this embodiment: the transmission mechanism includes a transmission gear disposed at one end of the roller 4 and a drive gear disposed on the rotating shaft of the motor 3. The transmission mechanism also includes a chain disposed on the drive gear and the transmission gear.

[0095] Unlike the above embodiments, this application further includes a driving gear and a driven gear, which are driven by the chain. Compared with the above embodiments, the advantage of this embodiment is that the transmission effect is better, and it gets rid of the problem of insufficient friction and easy slippage during belt transmission. The disadvantage of this embodiment is that the chain structure is complex, with transmission and linkage, and some structures are easily damaged, affecting the overall service life of the chain.

[0096] Please refer to the appendix here. Figure 11 Based on the performance parameters of the Roots blower, the inlet pipe diameter r1 = 40mm, the wind speed V1 = 40m / s, and the pressure P a =55kP a Fluid simulation analysis using the auxiliary software SolidWorks indicates that the throat velocity needs to reach approximately 70 m / s to achieve the designed outlet velocity of 18 m / s.

[0098] S1V1=S2V2=Q (1)

[0099] Formula for the area of ​​a circular tube

[0100] S=π·r 2 (2)

[0101] The diameter of the throat can be calculated from equations (1) and (2).

[0102]

[0103] The flow velocity of the gas after passing through the expansion section and entering the straight section must be maintained within a certain velocity range. The outlet pipe diameter can also be solved according to equations (1) and (2).

[0114] Substituting the volumetric flow rate, we can obtain

[0116] but

[0117]

[0118] Therefore, the design parameters for the vent pipe can be as follows:

[0119] Inlet diameter and height L1:

[0120] L1 = F a ·D (3)

[0121] =0.5×99

[0122] =49.5mm

[0123] The distance L2 between the outlet pipe wall and the separator wall:

[0124] L2 = F b ·D (4)

[0125] =0.2×99

[0126] =19.8mm

[0127] Air outlet diameter L3:

[0128] L3 = F c ·D (4)

[0129] =0.5×99

[0130] =49.5mm

[0131] Length L of the exhaust pipe:

[0132] L=0.65D (5)

[0133] =0.65×99

[0134] =64.4mm

[0135] Then, the separation height is calculated based on the optimal theoretical parameter values.

[0136] The height H of the straight section of the cylinder a :

[0137] H a =1.5D (6)

[0138] =1.5×99

[0139] =148.5mm

[0140] Total height H of the cylinder:

[0141] H = 4D (7)

[0142] =4×990

[0143] =396mm

[0144] In the above formula, F a ,F b ,F c These are the optimal parameter coefficient values ​​for the width, height, and discharge pipe diameter of the separator's air inlet, respectively.

[0145] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.

When two adjacent blades (5) rotate with the roller (4) to the top of the distributing bucket (202), the two blades (5) correspond to the two sides of the bottom opening of the feeding funnel (201) to achieve a temporary sealing effect. The roller (4) is symmetrically provided with baffles (7) at both ends. The baffles are located inside the material distribution barrel. The blade (5) is located between the two baffles (7). At least three ventilation holes (8) are provided on one of the baffles (7). Each ventilation hole (8) corresponds to a conveying unit (6). An air inlet (9) is provided on one side of the material distribution barrel (202). The air inlet (9) extends into the interior of the material distribution barrel (202). When the blade (5) rotates with the roller (4), it rotates to the conveying unit (6) at the lower part of the material distribution barrel (202). The ventilation hole (8) corresponding to it is opposite to the air inlet (9). The end of the air inlet (9) away from the material distribution barrel (202) is connected to an air conveying mechanism. The conveying mechanism (10) includes a conveying pipe (1001) connected to the bottom of the distributing hopper (202). The conveying pipe (1001) is a hollow mechanism with open ends. One end of the conveying pipe (1001) is connected to a power mechanism. The conveying mechanism (10) also includes a venturi tube (1002) connected to the other end of the conveying pipe (1001). The receiving mechanism (11) includes a separation chamber (1101), which is connected to a venturi tube (1002) via a connecting pipe (13). The separation chamber (1101) is a hollow structure with an open bottom. The conveying method steps are as follows: 1) Primary conveying of fermented mash; I. Start the motor (3), and the mash enters the inside of the distribution bucket (202) through the top of the feeding funnel (201); II. Each conveying unit (6) transports a limited amount of mash during the conveying process. The roller (4) rotates, causing the mash to move within the individual conveying unit (6) to prevent it from clumping together. III. Rotate to the lower part of the conveying unit (6) inside the distribution bucket (202), where the air inlet (9) and the ventilation port (8) are opposite each other. The air inlet (9) takes in air, and the lees located in the conveying unit (6) are further dispersed through the ventilation port (8) to prevent them from clumping together and sticking to the blades (5). 2) Secondary conveying of fermented mash; I. The mash continues to be transported and flows into the interior of the conveying pipe (1001) through the distribution bucket (202). The mash is further conveyed to the Venturi tube (1002) by the power mechanism. The mash flowing inside the Venturi tube (1002) has a speed difference, which further improves the looseness of the mash and prevents it from sticking together. II. The mash flows inside the Venturi tube (1002) to the connecting tube (13), and is then transported to the separation chamber (1101) via the connecting tube (13); In step 2, the separation chamber (1101) has a receiving pipe (12) integrally provided on its top edge. The receiving pipe (12) is connected to the connecting pipe (13), so that the mash enters the interior of the separation chamber (1101) through the connecting pipe (13) and the receiving pipe (12).
