Description

Technical Field

[0001] This utility model relates to the technical field of drying devices, specifically a fishmeal anti-oxidation drying device. Background Technology

[0002] Fishmeal, a high-protein feed rich in vitamins, is commonly used to feed poultry and livestock. Its processing involves multiple stages, including cooking, pressing, drying, and grinding. Among these, cooking and drying play a decisive role in fishmeal quality. Because fish fat is rich in highly unsaturated fatty acids, its oxidation rate far exceeds that of other animal and vegetable oils, making fishmeal highly susceptible to oxidation. Furthermore, the high-temperature steam used in cooking and drying, as well as the frictional heat generated during pressing and grinding, further promote the oxidation of fats in the fishmeal. Currently, the main heating and drying methods for fishmeal include direct-fire drying and steam drying. While direct-fire drying offers simple equipment structure, rapid heating, low energy consumption, and a large sample throughput per unit time, the excessively high temperatures (100-600℃) can easily lead to localized overheating of the material, causing damage to nutrients. Steam drying uses steam as an indirect heating medium, with drying temperatures generally between 90-130℃, producing relatively high-quality fishmeal; however, it suffers from high energy consumption and low production capacity. Meanwhile, improper control of drying time during the drying process can easily lead to fishmeal oxidation, protein deterioration, and reduced vitamin content, as well as protein loss and increased fat content in the fish feed. Current technologies largely rely on manual control of the cooking and drying environment; however, errors in this control can result in protein loss and unstable vitamin content in the fishmeal. Therefore, developing a device that effectively solves the problem of easy oxidation of fishmeal during drying and achieves efficient drying is of significant practical importance.

[0003] Application number CN201920396294.2 discloses a fishmeal drying device, comprising an inner cylinder with an outer intermediate cylinder fitted on its outer layer, and an outer cylinder fitted on the outer layer of the intermediate cylinder. The inner cylinder has a plurality of filter mesh holes evenly distributed on its outer circumference, and the intermediate cylinder has a plurality of filter mesh holes evenly distributed on its bottom. A bottom plate is fixedly connected to the bottom of the intermediate cylinder. A cover plate is fixedly connected to the flange opening at the upper end of the outer cylinder. The cover plate has a feed inlet communicating with the inner cylinder. An output shaft of a motor is connected to a reducer, and an output shaft of the reducer is connected to a component extending into the inner cylinder. The present invention utilizes an inner cylinder and an intermediate cylinder for two-stage separation and filtration. During the separation process, floating small particles are dried, while the large particles remaining inside the inner cylinder have large gaps, allowing high-temperature gas to easily pass through these gaps during stirring, resulting in high heating and drying efficiency and thus achieving separation and heating of fishmeal. However, the device has a shortcoming: when drying is complete and discharge is required, it cannot promptly block the agglomerated fishmeal inside, thus preventing the material from being completely dried. Utility Model Content

[0004] The purpose of this invention is to provide a fishmeal anti-oxidation drying device, which solves the problem that when the device is in use, after drying is completed and the material needs to be discharged, it cannot effectively block the clumping of fishmeal inside, thus preventing the material from being fully dried.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a fishmeal anti-oxidation drying device, including a box assembly.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4As shown, this utility model is a fishmeal anti-oxidation drying device, including a box assembly 1, a movable fixing assembly 2 is fixedly installed diagonally at the bottom of the box assembly 1, and a dispersing assembly 3 is fixedly installed inside one side of the box assembly 1. At the same time, a drying box assembly 4 is fixedly installed on the top of the other side of the box assembly 1, and a filter discharge cover assembly 5 is slidably installed on the top of the drying box assembly 4.

[0026] The filter discharge cover assembly 5 includes a limiting slide rail side plate 501. The two limiting slide rail side plates 501 are fixedly installed on both sides of the top of the sealing cover plate 404. The limiting slide rail side plate 501 is internally limited and installed with a return spring 502. The outer wall of the limiting slide rail side plate 501 is provided with a positioning groove 503. The limiting slide rail side plate 501 is slidably installed in the groove. The sealing slide plate 505 is fixedly installed in the middle of the two limiting slide plates 504.

[0027] By installing a filter discharge cover assembly 5 on the top of the device, when the internal drying is completed and the fishmeal needs to be discharged, the filter discharge cover assembly 5 can be used for filtering, thus preventing the discharge of clumped material.

[0028] The housing assembly 1 includes a low-position mounting box 101, a positioning side plate 102 is fixedly installed on the outer wall of the low-position mounting box 101, and a high-position mounting box 103 is fixedly installed on the other side of the low-position mounting box 101.

[0029] The movable fixing assembly 2 includes a rotating base 201, which is fixedly installed at the bottom diagonal positions of the low mounting box 101 and the high mounting box 103. A locking member 202 is rotatably installed at the bottom of the rotating base 201, and a moving wheel 203 is installed in the middle of the locking member 202.

[0030] The dispersing component 3 includes a rotary motor 301, which is fixedly installed inside the low-position mounting box 101. The end of the rotary motor 301 is located on the bottom side of the interior of the high-position mounting box 103. A drive gear 302 is fixedly installed at the end of the rotary motor 301. A driven gear 303 is connected to the top of the drive gear 302 via a transmission chain. The driven gear 303 is installed on the upper side of the inner wall of the high-position mounting box 103. A rotating rod 304 is fixedly installed in the middle of the driven gear 303. Dispersing fan blades 305 are fixedly installed around the outer wall of the rotating rod 304. The dispersing component 3 uses the rotary motor 301 to drive the drive gear 302, which in turn drives the driven gear 303 via the transmission chain. This causes the rotating rod 304 and the dispersing fan blades 305 to rotate, dispersing the fish meal, increasing the contact area between the fish meal and the drying device 402, and improving the drying efficiency.

[0031] The drying chamber assembly 4 includes a chamber body 401 and a drying device 402. The chamber body 401 is positioned above the low-position mounting box 101, and a rotating rod 304 is installed through the interior of the chamber body 401. A dispersing fan blade 305 is also installed inside the chamber body 401. The outer wall of the other side of the chamber body 401 is mounted on the inner wall of the positioning side plate 102 via an electrically controlled rotating mechanism 406. A sealing cover 404 is mounted on the top of the chamber body 401 via connecting hinges 403 on both sides. A filter groove 405 is opened in the middle of the sealing cover 404. The drying device 402 is fixedly installed on the inner wall of one side of the chamber body 401. The drying device 402 in the drying chamber assembly 4 heats and dries the fish meal. The electrically controlled rotating mechanism 406 can adjust the angle of the chamber body 401 to optimize the drying effect.

[0032] A movable handle 5051 is fixedly installed on the top of the outer wall of the sealing slide plate 505, and spring strip limit blocks 5052 are fixedly installed on the top of both sides of the outer wall of the sealing slide plate 505. The spring strip limit blocks 5052 are correspondingly limited and installed inside the positioning slot 503, and the spring strip limit blocks 5052 are adapted to the positioning slot 503. Under the action of the return spring 502, the positioning slot 503 and the spring strip limit blocks 5052, the sealing slide plate 505 of the filter discharge cover assembly 5 realizes the opening and closing control of the filter tank 405 of the sealing cover plate 404, filters and discharges the gas generated during the drying process, and prevents the fish meal from oxidizing.

[0033] This fishmeal anti-oxidation drying device mainly consists of a housing assembly 1, a movable and fixed assembly 2, a dispersing assembly 3, a drying chamber assembly 4, and a filter discharge cover assembly 5. Its working principle is based on the coordinated operation of each component, achieving fishmeal dispersing, drying, and gas filtration and discharge. The device's position can be moved and fixed via the movable and fixed assembly 2, facilitating flexible use. The dispersing assembly 3 uses a rotary motor 301 to drive the active gear 302, which in turn drives the passive gear 303 via a transmission chain, causing the rotating rod 304 and dispersing fan blades 305 to rotate, dispersing the fishmeal and increasing the contact area between the fishmeal and the drying device 402, thus improving drying efficiency. The drying device 402 in the drying chamber assembly 4 heats and dries the fishmeal. The electrically controlled rotary motor 406 can adjust the angle of the housing 401 to optimize the drying effect. The sealing slide plate 505 of the filter discharge cover assembly 5, under the action of the return spring 502, the positioning slot 503, and the spring-loaded limit block 5052, controls the opening and closing of the filter groove 405 of the sealing cover 404, thus filtration and discharge. To prevent oxidation of the fishmeal and to remove the gas generated during the drying process, the device is first moved to a suitable position using the moving wheels 203 in the moving and fixing assembly 2. The locking mechanism 202 is then rotated to lock the moving wheels 203, fixing the device onto the rotating bases 201 diagonally mounted at the bottom of the low-position mounting box 101 and the high-position mounting box 103. The fishmeal is then placed into the high-position mounting box 103, and the rotating motor 301 of the dispersing assembly 3 is started. The rotating motor 301 drives the end-effector gear. When 302 rotates, the driving gear 302 drives the driven gear 303 on the upper side of the inner wall of the high-position installation box 103 via the transmission chain. The driven gear 303 drives the rotating rod 304 in the middle and the dispersing fan blades 305 on the outer wall to rotate, dispersing the fish meal. Under the action of gravity, the dispersed fish meal falls from the high-position installation box 103 into the box 401 above the low-position installation box 101 below. The rotating rod 304 penetrates the box 401, and the dispersing fan blades 305 continue to tumble the fish meal inside the box. At the same time, the drying device 402 of the drying box assembly 4 is started to heat and dry the fish meal. The electrically controlled rotating mechanism 406 can adjust the angle of the box 401 as needed to make the fish meal dry more evenly. The gas generated during the drying process is discharged through the filter groove 405 in the middle of the sealing cover 404. When gas needs to be released, pull the moving handle 5051 on the top of the sealing slide plate 505, so that the sealing slide plate 505 overcomes the elastic force of the return spring 502 and slides in the groove of the limit slide rail side plate 501. The spring bar limit block 5052 disengages from the positioning groove 503, opening the filter tank 405, and the gas is released after filtration. After the gas is released, release the moving handle 5051. Under the action of the return spring 502, the sealing slide plate 505 resets, the spring bar limit block 5052 re-engages into the positioning groove 503, and the filter tank 405 is closed to prevent the fish meal from oxidizing. After drying, open the sealing cover plate 404 of the box 401 and take out the dried fish meal from the box 401 for collection.
