Description

Technical Field

[0001] The invention belongs to the technical field of feed production equipment, and in particular relates to a drying and shaping equipment for producing puffer fish compound feed. Background Art

[0002] Pufferfish is the official name of the relatively common fish "pufferfish". The raw materials of the above-mentioned pufferfish compound feed mainly include shrimp, fish bones, crab shells, fish meal, rapeseed meal, wheat bran, and corn flour. Pufferfish compound feed belongs to protein aquatic feed, and its protein content is generally 40-50%.

[0003] On the other hand, the production method of puffer fish compound feed is generally consistent with the general aquatic feed production method, which mainly includes batching, mixing, conditioning, puffing and granulation, drying, and cooling. The above-mentioned drying and shaping equipment is set at the discharge port of the puffing and granulation machine to heat the moist and relatively soft feed particles.

[0004] The common drying and shaping equipment currently available mainly includes a conveying mechanism and a heating mechanism. The former can be a conveyor belt, a screw conveyor, or even an inclined pipeline, and the latter is mainly heated by an electric heating wire.

[0005] For example, a Chinese utility model patent with authorization announcement number CN217504234U and authorization announcement date 2022.09.27 discloses a rapid dryer for aquatic feed production, including a mixing box, the surface of the mixing box is connected to a fixed frame, the inner wall of the fixed frame is connected to a DC servo motor, and the servo motor is connected to the inner wall of the mixing box through a screw rod, the output end of the DC servo motor is connected to a rotating column through a screw rod, the rotating column is located inside the mixing box, and the tail end of the rotating column is connected to the inner wall of the mixing box through a bearing, and the surface of the rotating column is connected to a stirring rod.

[0006] The general structural principle and advantages of the rapid dryer in this utility model patent are as follows: a servo motor, a stirring rod and an electric push rod are installed to effectively avoid blockage during the feed feeding process. The servo motor is used to drive the rotating column to rotate through the screw rod, and the rotating column drives the stirring rod to rotate. The stirring rod breaks up the condensed feed during the rotation process. At the same time, the electric push rod is used to drive the movable claw to move up and down, thereby pushing the feed to move downward.

[0007] However, in actual use, the quick dryer still has at least the following two shortcomings, which are also the technical problems to be solved by the present invention, namely: First, the drying tank lacks the necessary feed quantity control function. Under the premise of unchanged heating intensity, when the feed quantity increases unexpectedly, insufficient heating is likely to occur. This is untrue. Second, the discharge pipe lacks the necessary and timely cooling function, which means that the feed particles with higher temperature can only be cooled naturally relatively slowly, which will lead to multiple harmful phenomena such as feed deterioration and nutrient loss. Compared with starch-based aquatic feed, protein-based aquatic feed is more sensitive to the above-mentioned unexpected situations and will suffer greater losses.

[0008] Therefore, in summary, a new type of drying and shaping equipment with uniform and sufficient heating function and timely cooling function is urgently needed for the production of puffer fish feed to avoid obvious loss and deterioration of various nutrients in the feed during the natural cooling stage. Correspondingly, the feed particles discharged from the above equipment can be directly sieved and bagged, which is very convenient and efficient. Summary of the invention

[0009] The present invention provides a drying and shaping device for producing puffer fish compound feed, which can be arranged on a drying box unit in the manner of a conveyor belt, a heater, a transverse plate, and an inclined pipe unit, so that: 1. the transverse plate can scrape a wet material layer with a relatively uniform thickness on the conveyor belt, so that the heater has sufficient drying and shaping strength for the wet material; 2. the inclined pipe unit can perform timely active air cooling operation on the dried material, and compared with natural cooling, this method can greatly reduce the amount of protein lost and deteriorated.

[0010] The technical solution adopted by the present invention to solve the above-mentioned problem is: a drying and shaping equipment for the production of puffer fish compound feed, the structure of which includes a conveyor belt and a heater, and also includes a drying box unit for installing the conveyor belt and the heater inside, a horizontal plate arranged in the drying box unit and located above the conveyor belt and used for scraping wet materials, and an inclined pipe unit arranged on the drying box unit and used for air cooling the dried material.

[0011] A further preferred technical solution is that the drying box unit includes a rectangular box, a feed pipe and a dehumidification pipe arranged on both sides of the top plate of the rectangular box, and a discharge pipe arranged on the bottom plate of the rectangular box and located on the same side as the dehumidification pipe.

[0012] A further preferred technical solution is that the drying box unit further comprises a wet material discharge pipe which is arranged on the bottom plate of the rectangular box and is located at two sides of the discharge pipe.

[0013] A further preferred technical solution is that the inclined tube unit includes an inclined tube body whose higher end is connected to the discharge pipe, an exhaust pipe arranged on the inclined tube body, and a downward discharge hole arranged on the inclined tube body and whose height is lower than that of the exhaust pipe.

[0014] A further preferred technical solution is that: the inclined tube unit further includes an end plate with holes arranged on the lower end surface of the inclined tube body.

[0015] A further preferred technical solution is that the inclined pipe unit further comprises a fixed bristle body which is arranged on the downward discharge hole and is used to prolong the time that the feed particles are subjected to the air cooling operation by blocking the feed particles from falling.

[0016] A further preferred technical solution is that: a drying material filling pipe unit is also sleeved on the inclined pipe body.

[0017] A further preferred technical solution is that the dry material filling tube unit includes an outer tube sleeved on the inclined tube body, a dry material mass arranged inside the outer tube and located outside the inclined tube body, and an open hole plate arranged on the lower end surface of the outer tube and used to support the dry material mass.

[0018] A further preferred technical solution is that the dry material filling tube unit also includes movable capillaries which are arranged on the upper end surface of the outer tube and are located below the fixed capillaries, and are used to display the moisture absorption of the dry material mass by passively changing the feed particle discharge speed.

[0019] A further preferred technical solution is that the dry material filling pipe unit further comprises two side plates which are arranged on the upper surface of the outer pipe and are used to block and protect the falling wet material. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The following descriptions are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention.

[0030] As attached Figure 1-8 As shown, a drying and shaping equipment for the production of puffer fish compound feed includes a conveyor belt 11 and a heater 12, and also includes a drying box unit 1 for installing the conveyor belt 11 and the heater 12 inside, a horizontal plate 2 arranged in the drying box unit 1 and located above the conveyor belt 11 and used for leveling the wet material a, and an inclined pipe unit 3 arranged on the drying box unit 1 and used for air cooling the dried material b.

[0031] In this embodiment, there are two rollers 13, one of which is provided with the driving wheel 14, and the conveyor belt 11 is sleeved on the two rollers 13. In addition, the drying box unit 1 is fed from the upper side on one side and discharged from the lower side on the other side, and the heater 12 is located above the upper half of the conveyor belt 11.

[0032] At this point, the wet material a first falls on the conveyor belt 11, then passes through the heater 12, and finally falls on the conveyor belt 11, thereby achieving the basic drying and shaping effect of the wet feed particles. The dried material b falling from the drying box unit 1 has the advantage of having a fixed shape and not being easily adhered to each other.

[0033] In the moving direction of the wet material a, the horizontal plate 2 is upstream of the heater 12. The horizontal plate 2 is rectangular in shape, and its two ends are respectively connected to two opposite inner sides of the drying box unit 1. The horizontal plate 2 is parallel to the upper half of the conveyor belt 11, and the distance between the horizontal plate 2 and the upper half can be reasonably set with reference to the strength of the heater 12 and the wetness of the wet material a.

[0034] At this time, the heater 12 is first debugged in advance, and then the appropriate drying intensity is set, and then no further adjustment is required. A wet material layer with a consistent thickness, such as 1.5 cm thick, can continuously obtain a sufficient and appropriate drying effect. However, it should be noted that the horizontal plate 2 can only reduce the relatively large wet material addition speed, and cannot increase the relatively small wet material addition speed. Therefore, the appropriate addition speed of the wet material a should be equal to or slightly greater than the addition speed corresponding to the above-mentioned 1.5 cm layer thickness, and it is better to be larger than smaller.

[0035] The functions and characteristics of the inclined pipe unit 3 at least include: First, the intensity of the above-mentioned air cooling operation is adjustable, and / or the residence time of the dried material b therein is adjustable, and finally sufficient and appropriate cooling intensity is obtained, that is, the temperature of the cooled material c is relatively low, which meets the temperature requirements of subsequent steps such as screening and bagging, and the entire air cooling operation is energy-saving and emission-reducing as much as possible; Second, the drying material b cannot be allowed to accumulate in large quantities, that is, the wet material adding speed at the drying box unit 1 is roughly equal to the wet material falling speed on both sides when it is scraped flat, plus the cooled material discharge speed at the inclined pipe unit 3.

[0036] Finally, the drying and shaping equipment has the dual advantages of quantitative drying, sufficient drying, and active and relatively high-intensity cooling operation immediately after drying, which greatly upgrades the entire production process of puffer fish feed. The upgrades include, for example: reducing the loss of nutrients during the cooling stage; shortening the cooling time, and directly screening and bagging shortly after drying and shaping.

[0037] The drying box unit 1 includes a rectangular box 101, a feed pipe 102 and a dehumidification pipe 103 arranged on both sides of the top plate of the rectangular box 101, and a discharge pipe 104 arranged on the bottom plate of the rectangular box 101 and located on the same side as the dehumidification pipe 103.

[0038] In this embodiment, the drying box unit 1 is made of stainless steel, the feed pipe 102 and the falling position of the excess amount on both sides of the wet material after being scraped flat are located on the same side, and are relatively upstream of the moving direction of the wet material a, while the dehumidification pipe 103 and the discharge pipe 104 are located on the other side.

[0039] Among them, the roller 13 is inserted into the two side plates of the rectangular box 101, the driving wheel 14 is located on the outside of the rectangular box 101, the single-layer length of the conveyor belt 11, that is, the distance between the upper ends of the two rollers 13, is 70-80% of the length of the rectangular box 101, and the length of the heater 12 in the moving direction of the wet material, that is, the effective heating and drying length, is more than 50% of the single-layer length of the conveyor belt 11.

[0040] In addition, the heater 12 is a commercially available product, which is screwed and fixed in the rectangular box 101, and the distance between the heater 12 and the conveyor belt 11 is set as needed.

[0041] The drying box unit 1 further includes a wet material discharge pipe 105 which is arranged on the bottom plate of the rectangular box 101 and is located at two sides of the discharge pipe 104 .

[0042] In this embodiment, the discharge pipe 104 and the wet material discharge pipe 105 are both rectangular tubes, and their diameters are relatively large, at least larger than the width of the conveyor belt 11, to avoid residual wet material a and dried material b on the inner bottom surface of the rectangular box 101.

[0043] Accordingly, as attached Figure 3 As shown, the left and right positions of the discharge pipe 104 correspond to the downstream roller 13, and the left and right positions of the wet material discharge pipe 105 correspond to the cross plate 2, ensuring that the excess wet material leaked from both sides during the scraping operation and the dried material b can all fall down and leave the rectangular box 101.

[0044] The inclined tube unit 3 includes an inclined tube body 301 whose higher end is connected to the discharge tube 104 , an exhaust pipe 302 arranged on the inclined tube body 301 , and a downward discharge hole 303 arranged on the inclined tube body 301 and lower in height than the exhaust pipe 302 .

[0045] In this embodiment, the higher end of the inclined tube body 301 is connected to the lower end of the discharge pipe 104, the position of the exhaust pipe 302 is higher than the downward discharge hole 303, and the exhaust pipe 302 is on the side panel and the downward discharge hole 303 is on the bottom plate. This can fully prevent the dried material b from being directly sucked away at the exhaust pipe 302.

[0046] On the other hand, the exhaust pipe 302 will inevitably draw away a small amount of hot and humid air in the rectangular box 101, but the main source is still the relatively dry and relatively low-temperature air entering from the lower end of the inclined tube body 301. Therefore, the efficient cooling operation is still effective.

[0047] Finally, in the width direction of the bottom plate of the inclined tube body 301, the size of the downward discharge hole 303 is equal to the above-mentioned width size, so that all the cooled materials c are discharged from the downward discharge hole 303, thereby providing a structural basis for the subsequent expansion function of the inclined lower end of the inclined tube body 301.

[0048] It should be noted that, for the exhaust pipe 302, it will also take in air at the downward discharge hole 303, but this will not affect the cooling effect and the discharge effect of the cooled material c. The airflow entering from the downward discharge hole 303 is also relatively dry and relatively low in temperature.

[0049] The inclined tube unit 3 further includes an end plate 304 with holes arranged on the lower end surface of the inclined tube body 301 .

[0050] In this embodiment, the first function of the perforated end plate 304 is to intercept the cooled material c that accidentally passes over the downward discharge hole 303, so that it can be dug out and taken out at the downward discharge hole 303 when the equipment is shut down later.

[0051] The inclined pipe unit 3 further includes a fixed bristle body 305 which is arranged on the downward discharge hole 303 and is used to prolong the time for which the feed particles are subjected to the air cooling operation by blocking the feed particles from falling.

[0052] In this embodiment, the fixed bristle body 305 mainly functions to appropriately intercept the material at the downward discharge hole 303 so that the air cooling effect time can be appropriately prolonged.

[0053] Correspondingly, the size of the downward discharge hole 303 can also be set to be relatively small. For example, its length is the bottom plate width of the inclined tube body 301, and its width is 1-3 cm, so that the cooling airflow can enter the perforated end plate 304 as much as possible. This is also the structural basis for the subsequent expansion of the function of the perforated end plate 304.

[0054] The function of the fixed bristle body 305 is essentially to reduce the effective size of the downward discharge hole 303 .

[0055] The inclined tube body 301 is also sleeved with a drying material filling tube unit 4 .

[0056] In this embodiment, the above-mentioned extended function refers to the provision of the drying material filling pipe unit 4, which achieves the beneficial effect of greatly improving the airflow drying degree under the premise of slightly reducing the ventilation volume. Accordingly, for the cooling operation, its cooling intensity is as important as avoiding the drying material b from getting damp, and the latter is even more important.

[0057] At this point, for the air cooling operation, at the inclined pipe unit 3, the air flow mainly enters at the drying material loading pipe unit 4, first undergoes a drying effect, then blows the drying material b, and finally obtains the cooled material c.

[0058] The upper connection port of the inclined tube body 301 and the downward discharge hole 303 may be provided with a sufficient and appropriate airflow blocking structure / method in accordance with the prior art.

[0059] The dry material loading tube unit 4 includes an outer tube 401 sleeved on the inclined tube body 301, a dry material mass 402 arranged inside the outer tube 401 and located outside the inclined tube body 301, and a perforated plate 403 arranged on the lower end surface of the outer tube 401 and used to support the dry material mass 402.

[0060] In this embodiment, the inclined tube body 301 and the outer tube 401 are clamped by friction, and the dry material mass 402 refers to relatively light cotton fiber or linen fiber with relatively outstanding moisture absorption performance.

[0061] The amount of the dry material mass 402 can be set as needed, and its position and shape between the perforated end plate 304 and the perforated plate 403 can also be set as needed. For example, the dry material mass 402 is broken up as much as possible, evenly distributed in the above space, and bonded to the inner bottom surface of the outer tube 401.

[0062] The dry material filling tube unit 4 also includes a movable cap 404 which is arranged on the upper end surface of the outer tube 401 and is located below the fixed cap 305 and is used to display the moisture absorption of the dry material mass 402 by passively changing the feed particle discharge speed.

[0063] In this embodiment, the material of the movable hair body 404 is the same as that of the fixed hair body 305. The former is slightly lower than the latter and has all the above functions of the latter, with the only difference being in functional strength.

[0064] What is important is that when the moisture absorption of the dry material mass 402 gradually increases, it will pull the outer tube 401 downward, causing the latter to slowly separate from the inclined tube body 301. At this time, the movable bristles 404 are away from the fixed bristles 305, and the blocking and deceleration effect of the movable bristles 404 on the cooled material c is greatly reduced. An obvious phenomenon is that the discharge speed at the downward discharge hole 303 suddenly increases, indicating that the moisture absorption of the dry material mass 402 is relatively large, and the dry material mass 402 needs to be replaced as soon as possible. This is very clever and practical.

[0065] It should be noted that when the moisture absorption of the dry material mass 402 is large, it will collapse into a smaller mass without hindering the intake air cooling effect.

[0066] The dry material loading pipe unit 4 further includes two side plates 405 disposed on the upper surface of the outer pipe 401 and used to block and protect the falling wet material a.

[0067] In this embodiment, the first function of the drying material filling pipe unit 4 is to enable the air cooling operation of the inclined pipe unit 3 to have an airflow drying function to prevent the drying material b from getting damp.

[0068] The second function is achieved through the side plate 405, so that the excess wet material discharged from the wet material discharge pipe 105 and leaked from both sides of the conveyor belt during the scraping operation can be conveniently and efficiently collected.

[0069] Furthermore, the extension plate 406 is provided above the perforated plate 403 to prevent the wet material a from being brought into the perforated plate 403 by the airflow, otherwise the latter's opening will be blocked. Accordingly, the extension plate 406 guides the wet material a to the wet material basket 19, and the wet material basket 19 can be re-fed at the feed pipe 102 later.

[0070] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various modifications can be made within the knowledge of ordinary technicians in the technical field without departing from the purpose of the present invention. These are all non-creative modifications and are protected by patent law as long as they are within the scope of the claims of the present invention.
