Enzymatic powder oil processing spray dryer

Abstract

This invention relates to the field of spray drying technology, and more particularly to a spray dryer for enzymatic powdered oil processing. The dryer includes a shell, with a raw material box for storing powdered oil materials fixedly connected to the side wall of the shell. A conduit is fixedly connected to the top of the raw material box, and a pump body is fixedly connected to the top end of the conduit. A spray drying mechanism is located at the center of the top of the shell, and the end of the pump body's suction pipe extends into the interior of the spray drying mechanism. This invention utilizes a flexible inner cylinder within the drying tower to vibrate and dislodge materials adhering to the inner wall. Simultaneously, the centrifugal force generated by the high-speed rotation of the conical column drives the spring rod and movable push rod to continuously rotate along the inner wall of the annular limiting groove, achieving a squeezing and collision effect between the movable push rod and the elastic limiting block. This effectively dislodges the materials adhering to the inner wall, allowing the materials to fully contact the hot air for drying, improving the drying effect and ensuring the quality of the prepared materials.

Description

Technical Field

[0001] This invention relates to the field of spray dryer technology, and more particularly to a spray dryer for enzymatic powder and oil processing. Background Technology

[0002] Powdered oils, also known as fat powders, are widely used as auxiliary materials in various food processing. In the process of preparing raw materials by enzymatic methods, the powdered oil raw materials need to be dried by spray drying machine to obtain powdered or granular solid particles.

[0003] Existing spray dryers for enzymatic powder oil processing have the following technical defects: During the drying process of raw materials, the powder oil is highly viscous and easily adheres to the inner wall of the furnace. As a result, the powder oil adhering to the inner wall of the furnace cannot fully contact the hot air for drying, and the raw materials adhering to the inner wall of the furnace are difficult to clean, which affects the quality of raw material preparation. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a spray dryer for enzymatic powder and oil processing, which solves the technical problems of poor drying effect and low preparation efficiency caused by raw materials easily sticking to the inner wall of the furnace.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a spray dryer for enzymatic powder oil processing, comprising a shell, a raw material box for storing powder oil raw materials fixedly connected to the side wall of the shell, a conduit fixedly connected to the top of the raw material box, a pump body fixedly connected to the top end of the conduit, a spray drying mechanism provided at the top center of the shell, the end of the liquid extraction pipe of the pump body extending into the interior of the spray drying mechanism, a hot air fan provided on one side of the top of the shell, an air inlet pipe fixedly connected to the top of the hot air fan, the end of the air inlet pipe extending into the interior of the shell, and a discharge valve fixedly installed at the bottom of the side wall of the shell;

[0006] The spray drying mechanism includes a hopper rotatably installed at the center of the bottom wall of the housing, the end of the pump body's liquid extraction pipe extending to the center of the hopper, a centrifugal atomizer fixedly connected to the bottom of the hopper, a conical column fixedly connected to the center of the bottom wall of the centrifugal atomizer, and a drying tower sleeved on the outside of the spray drying mechanism, the drying tower being fixedly connected to the inner wall of the housing.

[0007] A spiral guide plate is fixedly connected to the outer side of the conical column. The spiral guide plate is arranged at equal intervals along the side wall of the conical column. The spiral guide plate is an inclined arc plate that gradually narrows from top to bottom. A vibration knocking mechanism is provided on the outer side of the conical column.

[0008] Preferably, the vibration knockdown mechanism includes a fixed cylinder fixedly connected to the outside of the conical column, a spring rod slidably mounted on the outside of the fixed cylinder, and a movable top rod fixedly connected to the outside of the spring rod.

[0009] The vibration knocking mechanism also includes a movable groove inside the drying tower. The movable groove has a flexible inner cylinder inside. The top and bottom inner walls of the flexible inner cylinder are fixedly fitted with annular connecting ribs. An elastic washer is fixedly connected to the outer side of the bottom of the flexible inner cylinder. The outer side of the elastic washer is fixedly fitted to the inner bottom wall of the movable groove. A conical cylinder for easy material discharge is fixedly connected to the bottom of the movable groove. An annular limiting groove is opened on the inner wall of the connection area between the conical cylinder and the drying tower.

[0010] Preferably, the bottom wall of the bottom annular connecting rib is fixedly connected with elastic limiting blocks at equal intervals, and the bottom wall end face of the elastic limiting block extends into the interior of the annular limiting groove.

[0011] The outer wall of the movable top rod is set as an arc-shaped surface, and the diameter of the annular limiting groove is greater than the diameter of the arc surface of the outer wall of the movable top rod.

[0012] The conical cylinder has an inclined guide pipe fixedly connected to its side wall at an angle, and the bottom end of the inclined guide pipe is connected to the discharge valve.

[0013] By means of the above technical solution, the present invention provides a spray dryer for enzymatic powder and oil processing, which has at least the following beneficial effects:

[0014] 1. This invention achieves the vibration knocking off of materials adhering to the inner wall of the drying tower by setting up a flexible inner cylinder. At the same time, the centrifugal force generated by the high-speed rotation of the conical column drives the spring rod and the movable top rod to continuously hit the annular connecting rib at the bottom, thereby realizing the vibration knocking of the flexible inner cylinder and effectively knocking off the materials adhering to the inner wall of the cylinder. This allows the materials to fully contact the hot air for drying, improves the drying effect, and ensures the quality of the prepared materials.

[0015] 2. This invention utilizes the centrifugal force generated by the continuous high-speed rotation of the conical column to ultimately achieve the sliding of the movable top rod to the inner wall of the annular limiting groove and its continuous rotation. Combined with the squeezing and collision between the movable top rod and the elastic limiting block, this enhances the vibration amplitude and further improves the effect of knocking down the material adhering to the inner wall of the cylinder, allowing the material to fully contact the hot air for drying, thus further improving the drying effect.

[0016] 3. This invention uses a centrifugal atomizer to spray raw materials at high speed, while the spiral guide plate makes the hot air in the furnace come into contact with the raw materials in a spiral shape. Compared with the traditional method of material being thrown down along the centrifugal atomizer and freely dispersed in contact with the hot air, this invention increases the impact impulse of the material when it comes into contact with the hot air, so that the material can be thoroughly dried and the drying effect of the material can be effectively enhanced.

[0017] 4. This invention achieves a uniform tapping effect by using movable top rods that are evenly spaced along the side wall of the conical column. At the same time, the intermittent tapping of the material adhering to the inner wall of the cylinder is ensured by the elastic limiting blocks that are evenly spaced at the bottom of the annular connecting ribs. This achieves the effect of tapping the adhering material with stable amplitude vibration, ensuring material feeding efficiency and making the dried material discharged evenly, thereby achieving a stable discharge effect.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Example 1

[0027] Please refer to Figures 1-2 A spray dryer for enzymatic powdered oil processing includes a shell 1. A raw material box 2 for storing powdered oil raw materials is fixedly connected to the side wall of the shell 1. A conduit 3 is fixedly connected to the top of the raw material box 2. A pump body 4 is fixedly connected to the top end of the conduit 3. A spray drying mechanism 5 is provided at the top center of the shell 1. The end of the liquid extraction pipe of the pump body 4 extends into the interior of the spray drying mechanism 5. A hot air blower 6 is provided on one side of the top of the shell 1. An air inlet pipe 7 is fixedly connected to the top of the hot air blower 6. The end of the air inlet pipe 7 extends into the interior of the shell 1. When drying begins, the pump body 4 is turned on to draw the powdered oil material to be dried from the raw material box 2 into the interior of the shell 1 through the conduit 3. Then, the hot air blower 6 is turned on to pour hot air into the interior of the shell 1 through the air inlet pipe 7. Then, the spray drying mechanism 5 is turned on to achieve the drying treatment of the material. A discharge valve 8 is fixedly installed at the bottom of the side wall of the shell 1 of the pump body 4.

[0028] The spray drying mechanism 5 includes a hopper 50 rotatably mounted at the center of the bottom wall of the housing 1. The end of the pump body 4 extends through to the center of the hopper 50. A centrifugal atomizer 51 is fixedly connected to the bottom of the hopper 50. After the centrifugal atomizer 51 is turned on, it rotates continuously, causing the raw material to be centrifugally sprayed along the outside of the centrifugal atomizer 51 and fully contacted with the hot air inside the drying tower 9 for drying. A conical column 52 is fixedly connected to the center of the bottom wall of the centrifugal atomizer 51. The drying tower 9 is sleeved on the outside of the spray drying mechanism 5 and is fixedly connected to the inner wall of the housing 1.

[0029] As a preferred technical solution in this embodiment, a spiral guide plate 53 is fixedly connected to the outer side of the conical column 52. As the spiral guide plate 53 on the outer side of the conical column 52 continues to rotate and continuously contacts the hot air inside the drying tower 9, the hot air inside the drying tower 9 flows in a spiral manner. The raw material is sprayed by the centrifugal atomizer 51 under high-speed rotation. At the same time, the contact of the spiral guide plate 53 makes the hot air in the furnace contact the raw material in a spiral shape. Compared with the traditional contact method of material being thrown down along the centrifugal atomizer and freely dispersed in contact with the hot air, this increases the impact impulse of the material when it collides with the hot air, so that the material can be thoroughly dried and the drying effect of the material is effectively enhanced. The spiral guide plate 53 is set at equal intervals along the side wall of the conical column 52. The spiral guide plate 53 is an inclined arc plate that gradually narrows from top to bottom. The spiral guide plate 53 continuously collides with the hot air, thereby making the hot air inside laterally tangential, ensuring that the hot air flows in a spiral rotation. A vibration knocking mechanism is provided on the outer side of the conical column 52.

[0030] Example 2

[0031] Please refer to Figures 3-4 This embodiment is basically the same as Embodiment 1. This embodiment is made on the basis of Embodiment 1 and has the same beneficial effects as Embodiment 1. The same parts can be referred to each other, and will not be described in detail here.

[0032] The vibration knockdown mechanism includes a fixed cylinder 54 fixedly connected to the outside of the conical column 52. A spring rod 55 is slidably installed on the outside of the fixed cylinder 54. A movable top rod 56 is fixedly connected to the outside of the spring rod 55. As the conical column 52 and the fixed cylinder 54 continue to rotate, the spring rod 55 slides outward continuously under the centrifugal force during rotation, which in turn causes the movable top rod 56 to slide outward continuously.

[0033] The vibration knockdown mechanism also includes a movable groove 90 located inside the drying tower 9. A flexible inner cylinder 91 is provided inside the movable groove 90. Annular connecting ribs 93 are fixedly sleeved on the top and bottom inner walls of the flexible inner cylinder 91. An elastic washer 92 is fixedly connected to the bottom outer side of the flexible inner cylinder 91. The outer side of the elastic washer 92 is fixedly sleeved on the inner bottom wall of the movable groove 90. A conical cylinder 10 for easy material discharge is fixedly connected to the bottom of the movable groove 90. An annular limiting groove 94 is provided on the inner wall of the connection area between the conical cylinder 10 and the drying tower 9. During the rotation of the movable top rod 56, it continuously slides outward due to centrifugal force, and then contacts and collides with the elastic washer 91 at the bottom of the flexible inner cylinder 91, causing the flexible inner cylinder 91 to deform. At this time, the raw material adhering to the inner wall of the flexible inner cylinder 91 is knocked down for the first time.

[0034] Example 3

[0035] Please refer to Figures 2-5This embodiment is basically the same as Embodiment 1. This embodiment is made on the basis of Embodiment 1 and has the same beneficial effects as Embodiment 1. The same parts can be referred to each other, and will not be described in detail here.

[0036] The bottom wall of the bottom annular connecting rib 93 is fixedly connected with elastic limiting blocks 95 at equal intervals. The movable top rods 56, evenly spaced along the side wall of the conical column 52, achieve a uniform tapping effect. Simultaneously, the elastic limiting blocks 95 at equal intervals at the bottom of the annular connecting rib 93 ensure intermittent tapping of the material adhering to the inner wall of the cylinder, achieving a stable amplitude vibration tapping effect on the adhering material, ensuring efficient material feeding, and ensuring uniform discharge of the dried material. The bottom wall end face of the elastic limiting block 95 extends into the interior of the annular limiting groove 94. As the movable top rod 56 continues to rotate at high speed, it rotates at its maximum centrifugal speed and eventually slides into the interior of the annular limiting groove 94. As the inner wall of the circumferential limiting groove 94 rotates continuously, it constantly contacts and collides with the elastic limiting block 95 at the bottom of the annular connecting rib 93, increasing the vibration amplitude. This causes the flexible inner cylinder 91 to vibrate continuously and accelerate, enhancing the vibration amplitude. The flexible inner cylinder 91 on the inner wall of the drying tower 9 enables the vibration to knock off the material adhering to the inner wall of the cylinder. At the same time, the conical column 52, under the centrifugal force generated by high-speed rotation, drives the spring rod 55 and the movable top rod 56 to rotate continuously along the inner wall of the annular limiting groove 94, achieving the squeezing and collision effect between the movable top rod 56 and the elastic limiting block 95. This effectively knocks off the material adhering to the inner wall of the cylinder, allowing the material to fully contact the hot air for drying, improving the drying effect and ensuring the quality of the prepared material.

[0037] As a preferred technical solution in this embodiment, the outer wall of the movable top rod 56 is set as an arc-shaped surface, and the diameter of the annular limiting groove 94 is greater than the diameter of the arc surface of the outer wall of the movable top rod 56, so as to ensure that when the movable top rod 56 rotates along the inside of the annular limiting groove 94, it contacts and collides with the elastic limiting block 95, so as to ensure that the material adhering to the inner wall of the flexible inner cylinder 91 is shaken off by vibration.

[0038] As a preferred technical solution in this embodiment, the side wall of the conical cylinder 10 is fixedly connected with an inclined guide pipe 11. The bottom end of the inclined guide pipe 11 is connected to the discharge valve 8 through the pipe. The material is discharged at an incline along the discharge valve 8 through the inclined guide pipe 11 on the side wall of the conical cylinder 10.

The power supply is also common knowledge in the art. Furthermore, since this invention is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail here.
