Description

Technical Field

[0001] The invention relates to the technical field of food processing, and in particular to a device and a method for preparing fiber powder. Background Art

[0002] Spray drying is a method of drying materials. The thin material is atomized in a drying tower and high-temperature gas is introduced to quickly vaporize the water so that the water is quickly separated from the product, thereby obtaining a dry product. It is more common in the food and drug processing industry, such as milk powder, medicines, fiber powder, and instant drinks.

[0003] When the fiber powder is spray-dried by a spray drying tower, it is usually necessary to preheat the inside of the drying tower before spray drying. First, it is to provide preheating time for the heating box so that the heat provided by the heating box meets the requirements of spray drying. Second, it is to preheat the inner wall of the drying tower to prevent the phenomenon of wall sticking during spraying. Third, it is to reserve a large amount of heating gas in the drying tower to improve the efficiency of spray drying. However, the existing spray drying tower is an integral whole when leaving the factory, especially the large-capacity drying tower used for fiber powder drying, which has a large internal volume and a long preheating time. Moreover, since high-temperature gas is introduced during preheating, the gas is mostly accumulated on the top inner wall of the drying tower during the preheating process, so that the temperature is lower as it is closer to the bottom inner wall of the drying tower. In order to obtain sufficient preheating and ensure that the material does not stick to the wall, a long preheating time is required, which reduces the production efficiency. Moreover, the spray drying tower has been welded when leaving the factory, and the entire tank body needs to be transported, so that a large-volume vehicle is required for transportation, which is not convenient for transportation. For this reason, we propose a preparation device and method for fiber powder. Summary of the invention

[0020] A method for using a fiber powder preparation device comprises the following steps:

[0021] S1: During installation, the air inlet pipe, the vacuum pump and the heating box are connected through the pipeline, and the liquid infusion pipe is connected to the liquid pump and the masterbatch solution tank in sequence through the pipeline. The two driving rods are respectively fixedly connected to the output shaft ends of the two driving motors, and the default state before use is that most of the upper tower body is located in the lower tower body, that is, the lower tower body and the upper tower body are in a retracted state;

[0022] S2: When in use, the gas is heated by the heating box and transported to the cavity formed by the upper tower body and the lower tower body through the atomizing nozzle by the vacuum pump. In the default state, the cavity space formed by the upper tower body and the lower tower body is small, and when the heated gas enters the cavity formed by the upper tower body and the lower tower body, it will gradually rise up after being sprayed from the atomizing nozzle due to the low density of the hotter gas;

[0023] S3: With the gradual preheating, the hot air accumulates from top to bottom, and with the interaction of heat, the inner walls of the upper tower body and the lower tower body are heated. When the hot air accumulates to the connection between the lower tower body and the first hollow tube, the hot air gradually rises upward through the first hollow tube and is discharged from the second hollow tube. Paraffin is poured into the storage tube. As the hot air continuously passes through the first hollow tube, the closed tube and the second hollow tube, the paraffin is gradually melted by the heat and its volume gradually expands. The force generated by the melting and expansion of the paraffin pushes the push pin, so that the push pin and the first electric sheet are also close to the second electric sheet until the second electric sheet contacts the first electric sheet, thereby completing the electrical connection between the two series-connected drive motors and the first electric sheet and the second electric sheet;

[0024] S4: The circuit is closed to drive the two driving rods to rotate, so that the threads on the driving rods act on one of the hinge sleeves, so that the height of the hinge frame gradually decreases until the extension rod presses the lifting plate downward and makes the two third electric sheets electrically connected to the coil contact. When the two third electric sheets contact, the coil generates electromagnetic force and overcomes the force of the first spring to adsorb the movable sheet made of metal. At the same time as the two third electric sheets contact, the second flange at the bottom of the lower tower body enters the docking plate and completes the sealing of the interface through the second sealing strip, and at the same time, the first flange completes the connection between the upper tower body and the lower tower body through the first sealing strip. The tower body is sealed. At the same time, while the coil generates electromagnetic force, the connecting rod and the sliding column fixed to the movable sheet move to one side of the lower tower body and through the inclined groove on the sliding sleeve, the originally opened sealing cover is closed through the hinge of the connecting handle and the hinge seat. The sliding column can only move horizontally, and through the limitation of the inclined groove, when the inclined groove moves in the direction of the lower tower body, the side surface of the sliding column is against the top inner wall of the inclined groove. Under the action of the lever, the bottom of the sealing cover tightly seals the second hollow tube. At this time, the inner walls of the upper tower body and the lower tower body are fully preheated and fully unfolded, and the preheating completion can be known from the sealing cover in the closed state.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] In the present invention, the drying tower is divided into two parts by the upper tower body and the lower tower body, and the lower tower body is received in the upper tower body for preheating, thereby reducing the space of the internal cavity, so that after the heating gas is introduced, the heating gas can quickly preheat the cavity formed by the upper tower body and the lower tower body, and shorten the preheating time of the lower tower body near the bottom inner wall, and the space occupied by transportation can be reduced by the telescopic upper tower body and the lower tower body, thereby facilitating the transportation of the upper tower body and the lower tower body.

[0027] In the present invention, as the heating gas is continuously introduced, the heating gas is introduced into the closed tube through the first hollow tube to melt and expand the paraffin in the storage tube, so that the first electric sheet on the push pin contacts the second electric sheet, so that the output end of the drive motor drives the drive rod to rotate, so that the lower tower body gradually descends until the two third electric sheets contact and the electromagnetic force generated by the coil disconnects the electrical connection between the first electric sheet and the second electric sheet, so that the upper tower body and the lower tower body are preheated and sealed at this time, and the discharge pipe at the bottom of the lower tower body is connected and sealed with the discharge pipe, so that when sufficient preheating conditions are reached, the lower tower body automatically moves down and completes the sealing and enters the state of waiting for operation while improving the preheating efficiency. The length of the upper tower body and the lower tower body is increased to ensure that the mist material has a sufficiently long falling time, so that the mist material has a sufficiently long time to exchange heat with the hot air, thereby improving the drying effect, and shortening the length of the upper tower body and the lower tower body is to reduce the inner cavity capacity to ensure that a small amount of hot air is introduced to achieve a more efficient preheating effect.

In the default state, the cavity space formed by the upper tower body 301 and the lower tower body 402 is small, and the heated gas enters the cavity formed by the upper tower body 301 and the lower tower body 402. When the hot air is in the cavity formed, the hot gas will gradually rise upward after being ejected from the atomizing nozzle 19 due to its low density.

The two driving rods 17 are respectively fixedly connected to the output shaft ends of the two driving motors, and the default state before use is that most of the upper tower body 301 is located in the lower tower body 402, that is, the lower tower body 402 and the upper tower body 301 are in a contracted state;

[0060] S2: When in use, the gas is heated by the heating box and transported to the cavity formed by the upper tower body 301 and the lower tower body 402 through the atomizing nozzle 19 by the vacuum pump. In the default state, the cavity space formed by the upper tower body 301 and the lower tower body 402 is small, and when the heated gas enters the cavity formed by the upper tower body 301 and the lower tower body 402, the hotter gas will gradually rise up after being ejected from the atomizing nozzle 19 due to its low density;

[0061] S3: With the gradual preheating, the hot air accumulates from top to bottom, and with the interaction of heat, the inner walls of the upper tower body 301 and the lower tower body 402 are heated. When the hot air accumulates to the connection between the lower tower body 402 and the first hollow tube 501, the hot air gradually rises upward through the first hollow tube 501 and is discharged from the second hollow tube 507. Paraffin is poured into the storage tube 503. As the hot air continuously passes through the first hollow tube 501, the sealing tube 502 and the second hollow tube 507, the paraffin is gradually melted by the heat and its volume gradually expands. The force generated by the melting and expansion of the paraffin pushes the push pin 504, so that the push pin 504 and the first electric sheet 506 are also close to the second electric sheet 603 until the second electric sheet 603 contacts the first electric sheet 506, so that the two series-connected drive motors are electrically connected to the first electric sheet 506 and the second electric sheet 603.

[0062] S4: The circuit is closed to drive the two driving rods 17 to rotate, so that the thread on the driving rod 17 acts on one of the hinge sleeves 16, so that the height of the hinge frame 15 gradually decreases until the extension rod 903 presses the lifting plate 904 downward and makes the two third electric sheets 907 electrically connected to the coil 702 contact. When the two third electric sheets 907 contact, the coil 702 generates electromagnetic force and overcomes the force of the first spring 704 to adsorb the movable sheet 602 made of metal. At the same time as the two third electric sheets 907 contact, the second flange 404 at the bottom of the lower tower body 402 enters the docking plate 12 and completes the sealing of the interface through the second sealing strip 14, and at the same time, the first flange 302 completes the sealing of the upper tower body 301 and the lower tower body 402 through the first sealing strip 305. The upper tower body 301 and the lower tower body 402 are sealed. At the same time, while the coil 702 generates electromagnetic force, the connecting rod 801 and the sliding column 802 fixedly connected to the movable sheet 602 move to one side of the lower tower body 402 and close the originally opened sealing cover 807 through the hinge of the connecting handle 805 and the hinge seat 806 through the inclined groove 804 on the sliding sleeve 803. The sliding column 802 can only move horizontally, and the inclined groove 804 is limited so that when the inclined groove 804 moves in the direction of the lower tower body 402, the side surface of the sliding column 802 is against the top inner wall of the inclined groove 804. Under the action of the lever, the bottom of the sealing cover 807 tightly seals the second hollow tube 507. At this time, the inner walls of the upper tower body 301 and the lower tower body 402 are fully preheated and fully unfolded, and the preheating completion can be known from the sealing cover 807 in the closed state.

[0063] The use method and advantages of the present invention: The preparation device and method of the fiber powder, when used, has the following working process:

[0064] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 and Fig.12As shown, during installation, the air inlet pipe 21, the vacuum pump and the heating box are connected through a pipeline, and the infusion tube 20 is connected to the liquid extraction pump and the masterbatch solution box in turn through a pipeline. The two driving rods 17 are fixedly connected to the output shaft ends of the two driving motors respectively, and the default state before use is that most of the upper tower body 301 is located in the lower tower body 402, that is, the lower tower body 402 and the upper tower body 301 are in a contracted state. When in use, the gas is heated by the heating box and the heated gas is transported to the cavity formed by the upper tower body 301 and the lower tower body 402 through the atomizing nozzle 19 through the vacuum pump. In the default state, the cavity space formed by the upper tower body 301 and the lower tower body 402 is small, and the heated gas enters the cavity formed by the upper tower body 301 and the lower tower body 402. During the heating process, since the hotter gas has a low density, it will gradually rise upward after being ejected from the atomizing nozzle 19. As the hot air is gradually preheated, the hot air accumulates from top to bottom, and as the heat interacts, the inner walls of the upper tower body 301 and the lower tower body 402 are heated. When the hot air accumulates at the connection between the lower tower body 402 and the first hollow tube 501, the hot air gradually rises upward through the first hollow tube 501 and is discharged from the second hollow tube 507. Paraffin is poured into the storage tube 503. As the hot air continuously passes through the first hollow tube 501, the sealing tube 502 and the second hollow tube 507, the paraffin is gradually melted by the heat and its volume gradually expands. The force generated by the melting and expansion of the paraffin pushes the push pin 504, so that the push pin 504 together with the first electric sheet 506 The second electric sheet 603 is also approached until the second electric sheet 603 contacts the first electric sheet 506, so that the two driving motors connected in series are electrically connected to the first electric sheet 506 and the second electric sheet 603, so that the circuit is closed to drive the two driving rods 17 to rotate, so that the thread on the driving rod 17 acts on one of the hinge sleeves 16, so that the height of the hinge frame 15 gradually decreases, until the extension rod 903 presses the lifting plate 904 downward, and makes the two third electric sheets 907 electrically connected to the coil 702 contact. When the two third electric sheets 907 contact, the coil 702 generates an electromagnetic force and overcomes the force of the first spring 704 to adsorb the movable sheet 602 made of metal. At the same time as the two third electric sheets 907 contact, the movable sheet 602 located at the lower tower The second flange 404 at the bottom of the tower body 402 enters the docking plate 12 and completes the sealing of the interface through the second sealing strip 14, and at the same time, the first flange 302 completes the sealing of the upper tower body 301 and the lower tower body 402 through the first sealing strip 305. At the same time, when the coil 702 generates electromagnetic force, the connecting rod 801 and the sliding column 802 fixed on the movable sheet 602 move to one side of the lower tower body 402, and through the inclined groove 804 on the sliding sleeve 803, the originally opened sealing cover 807 is closed through the hinge connection of the connecting handle 805 and the hinge seat 806. The sliding column 802 can only move horizontally, and the inclined groove 804 is limited so that when the inclined groove 804 moves in the direction of the lower tower body 402, the side surface of the sliding column 802 abuts against the top inner wall of the inclined groove 804.Under the action of the lever, the bottom of the sealing cover 807 tightly seals the second hollow tube 507. At this time, the inner walls of the upper tower body 301 and the lower tower body 402 are completely preheated and fully expanded, and the preheating is completed through the closed state of the sealing cover 807.

In a default state, the cavity formed by the upper tower body (301) and the lower tower body (402) has a small space. When the heated gas enters the cavity formed by the upper tower body (301) and the lower tower body (402), the heated gas gradually rises upward after being ejected from the atomizing nozzle (19) due to the low density of the hotter gas.

Under the action of the lever, the bottom of the sealing cover (807) tightly seals the second hollow tube (507). At this time, the inner walls of the upper tower body (301) and the lower tower body (402) are completely preheated and fully unfolded, and the preheating completion can be known from the closed state of the sealing cover (807).
