Description

Technical Field

[0001] The present invention relates to the technical field of evaporation drying, and particularly relates to an evaporation separation dryer for broccoli seed fermentation product liquid in a low-pressure environment. Background Art

[0002] Broccoli seed fermentation product liquid is a product made by fermenting broccoli seeds. After fermentation treatment, a variety of beneficial metabolites and active ingredients can be produced, and these beneficial metabolites and active ingredients can only be obtained through evaporation and separation.

[0003] At this time, an evaporation separation dryer for broccoli seed fermentation product liquid is mentioned. The evaporation separation dryer for broccoli seed fermentation product liquid is a device used to evaporate the water in a liquid product and finally obtain dry powder or particles. When preparing broccoli seed fermentation product liquid, the liquid product obtained after fermentation contains a certain amount of water and needs to be processed by an evaporation separation dryer to be converted into a dry form.

[0004] For example, Chinese Patent with publication number CN113289359A discloses an application related to a vacuum low-temperature belt dryer, which includes a raw material stirring barrel, a cloth feeding device, and a vacuum drying tank body. A conveying rack is arranged inside the vacuum drying tank body, and a conveyor belt for conveying materials is arranged on the conveying rack. The cloth feeding device includes a feeding pipe connected to the raw material stirring barrel, a feeding pump arranged on the feeding pipe, a cloth feeding pipe arranged on the conveying rack and above the conveyor belt, and a cloth feeding head connected to the cloth feeding pipe. The cloth feeding pipe is connected to the feeding pipe, and a plurality of cloth feeding heads are arranged along the axis of the cloth feeding pipe. The axial direction of the cloth feeding pipe is parallel to the width direction of the conveyor belt, which has the effect of improving the drying efficiency of materials.

[0005] However, there are still some deficiencies in the above dryer during actual use: 1. First, in the above-mentioned prior art, the materials are evenly laid on the conveyor belt through the cloth feeding head, so that the materials are evenly distributed on the conveyor belt, thereby effectively improving the drying efficiency of the materials; but the raw materials are processed inside the vacuum drying tank body during evaporation. Therefore, in a vacuum state, the raw materials laid on the conveyor belt are extremely likely to splash due to the vacuum environment. At the same time, during the evaporation process, a large number of bubbles are generated due to the evaporation of the water in the raw materials. During the process of the bubbles bursting, the raw materials will splash and diffuse throughout the vacuum drying tank body. As the entire equipment works for a long time, finally, a large amount of solidified raw materials will adhere to the inside of the equipment and it is difficult to clean.

[0006] 2. Secondly, in the prior art, after the raw materials are laid on the conveyor belt, the raw materials are evaporated and dried on the conveyor belt. After the raw materials are dried, solid raw materials with the same shape as the conveyor belt are formed on the surface of the conveyor belt. At this time, the raw materials are forced to separate from the conveyor belt as the conveyor belt rotates. However, the separation of the raw materials from the conveyor belt is not thorough enough, and small lumps of raw materials with uneven surfaces will adhere to the surface of the conveyor belt. With the subsequent processing of the raw materials, more small lumps of raw materials will adhere to the surface of the conveyor belt. If not cleaned, it will cause deterioration and affect the drying of subsequent raw materials.

[0007] Therefore, under the viewpoints stated above, there is still room for improvement in the existing drying machine. Summary of the Invention

Detailed implementation manners

[0039] The following will Figures 1-11 be described in detail with reference to the embodiments of the present invention. However, the present invention can be implemented in many different ways defined and covered by the claims.

[0040] The embodiment of the present application discloses an evaporation separation dryer for broccoli seed fermentation product liquid in a low-pressure environment. It should be noted that this dryer is mainly used in the process of evaporating and drying broccoli seed fermentation product liquid. First of all, in the prior art, the evaporation of broccoli seed fermentation product liquid is carried out in a vacuum environment. Therefore, in a vacuum state, the laid raw materials are likely to splash due to the vacuum environment. At the same time, during the evaporation process, a large number of bubbles are generated due to the evaporation of water in the raw materials, and when they burst, it will also cause the raw materials to splash and diffuse inside the entire dryer. As the entire equipment works for a long time, it will eventually lead to a large amount of solidified raw materials adhering to the inside of the equipment and being difficult to clean.

[0041] Secondly, in the prior art, the raw materials need to come into contact with the heating equipment, and then the raw materials are heated and evaporated. However, in the prior art, the solid raw materials that have been heated and formed are not separated from the heating equipment thoroughly enough, and small lumpy raw materials with uneven surfaces will adhere to their surfaces. As the subsequent processing of the raw materials continues, more small lumpy raw materials will adhere to the surface of the equipment. If not cleaned, it will cause them to deteriorate and affect the drying of the subsequent raw materials.

[0042] Embodiment 1: Refer to Figure 1 and Figure 2 As shown, an evaporation separation dryer for broccoli seed fermentation product liquid in a low-pressure environment includes a drying box 1. Inside the drying box 1, there is an evaporation drying operation board 6 for placing and spraying the fermentation liquid, and the evaporation drying operation board 6 is rotatably arranged in the middle of the drying box 1. The evaporation drying operation board 6 is of an I-shaped structure, and the inside of the evaporation drying operation board 6 is a hollow structure. A temperature equalizing plate for heating is attached to the inner wall of the evaporation drying operation board 6.

[0043] It should be noted that a temperature equalizing plate capable of heating is arranged inside the evaporation drying operation board 6, and the heating temperature is low.

[0044] Because of the characteristics of broccoli seed fermentation product liquid itself, it can only withstand a relatively low temperature. If the temperature is too high, it will cause the product characteristics of broccoli seed fermentation product liquid to change, and even worse, it will cause the broccoli seed fermentation product liquid to deteriorate. By means of vacuum and low pressure, the liquid can boil and evaporate at a lower temperature, which can effectively reduce the boiling point of the material, avoid the destruction of nutrients by high temperature, and maintain its original physical and chemical properties and biological activities.

[0045] It should be noted that both sides of the evaporation drying operation board 6 can evaporate and dry the broccoli seed fermentation product liquid, and the evaporation drying operation board 6 can rotate intermittently by 180 degrees.

[0046] Refer to Figure 2As shown, it is a schematic structural diagram for preprocessing the broccoli fermentation product liquid during the processing of the broccoli fermentation product liquid in the present application. Specifically, a storage tank 13 for storing the broccoli seed fermentation product liquid is provided at the upper end of the drying oven 1. A conveying pipeline 14 for conveying the fermentation liquid is connected to the storage tank 13. The conveying pipeline 14 penetrates through the drying oven 1 and extends towards the isolation cavity 11 inside the drying oven 1. One end of the conveying pipeline 14 away from the storage tank 13 is connected to a fog-making nozzle 15 for spraying the fermentation liquid. And a horizontal sliding groove 16 for the movement of the fog-making nozzle 15 is opened on the partition plate 10.

[0047] A partition plate 10 is provided inside the drying oven 1, dividing the drying oven 1 into an isolation cavity 11 and an evaporation cavity 12 for evaporating the fermentation liquid.

[0048] When it is necessary to evaporate and dry the broccoli seed fermentation product liquid, first prepare the broccoli seed fermentation product liquid in advance, and then fill the broccoli seed fermentation product liquid into the storage tank 13 specifically used for storing the broccoli seed fermentation product liquid, and it is necessary to ensure the tightness of the broccoli seed fermentation product liquid.

[0049] After the entire device is inspected, a vacuum operation is started inside the drying oven 1, so that the inside of the entire drying oven 1 is in a vacuum and low-pressure environment. Then, the valve of the storage tank 13 is opened, so that the broccoli seed fermentation product liquid is conveyed into the drying oven 1 through the conveying pipeline 14. Then, the broccoli seed fermentation product liquid enters the fog-making nozzle 15 through the conveying pipeline 14. At the same time, an electric push rod 17 is also provided in the isolation cavity 11 of the drying oven 1, and the output end of the electric push rod 17 faces downward and is connected to the fog-making nozzle 15.

[0050] The electric push rod 17 drives the fog-making nozzle 15 to move downward until the fog-making nozzle 15 abuts against the evaporation and drying operation plate 6. Then, the broccoli seed fermentation product liquid is sprayed onto the area of the evaporation and drying operation plate 6 inside the drying oven 1 for evaporating the broccoli seed fermentation product liquid through the fog-making nozzle 15. Then, the water in the broccoli seed fermentation product liquid starts to evaporate after contacting the evaporation and drying operation plate 6 and is gradually dried.

[0051] Refer to Figure 2 and Figure 3 As shown, it is a schematic structural diagram for controlling the movement of the fog-making nozzle 15 along the horizontal sliding groove 16. An electric slide rail 42 is also provided in the isolation cavity 11 of the drying oven 1, and the fog-making nozzle 15 is slidably installed on the electric slide rail 42 through an electric slider 43.

[0052] When the mist nozzle 15 starts to spray the broccoli seed fermentation product liquid downward, the broccoli seed fermentation product liquid will contact the evaporation and drying work plate 6. At the same time, the electric slide rail 42 drives the mist nozzle 15 to be transported and moved along the length direction of the drying box 1 through the electric slider 43. As the mist nozzle 15 is transported and moved, the mist nozzle 15 evenly sprays the broccoli seed fermentation product liquid onto the entire upper surface of the evaporation and drying work plate 6. After the evaporation and drying work plate 6 continuously heats the broccoli seed fermentation product liquid at a low temperature, the moisture in the broccoli seed fermentation product liquid is evaporated until the broccoli seed fermentation product liquid gradually changes from liquid to solid, and a rectangular structure of broccoli seed fermentation product is formed on the upper surface of the evaporation and drying work plate 6.

[0053] In the above description, the broccoli seed fermentation product liquid can be evenly sprayed onto the evaporation drying work plate 6 through the mist nozzle 15, but in the process of spraying the broccoli seed fermentation product liquid, the broccoli seed fermentation product liquid may splash, causing the broccoli seed fermentation product liquid to adhere to the inner wall of the entire drying box 1. After it is dried, small solid blocks are formed on the inner wall of the drying box 1, which are not only difficult to clean, but also cause them to get stuck in some tight parts of the equipment, causing damage to the equipment.

[0054] Therefore, the present application also proposes an anti-diffusion mechanism 2, which can prevent the broccoli fermentation product liquid from splashing randomly when the mist nozzle 15 sprays the broccoli fermentation product liquid, thereby ensuring the cleanliness of the interior of the drying box 1, and also avoiding the waste of broccoli fermentation liquid, which leads to increased costs, as shown below.

[0055] Reference Figure 4 , Figure 5 and Figure 6 As shown, an anti-diffusion mechanism 2 is provided between the evaporative drying work plate 6 and the fog-generating nozzle 15. The anti-diffusion mechanism 2 includes a fixed plate 20, a telescopic cover plate 21, a 匚-shaped bracket 22 and a rotating wheel 23. The fixed plates 20 are symmetrically installed on both sides of the width direction of the fog-generating nozzle 15, and the telescopic cover plate 21 is symmetrically clamped on the two fixed plates 20, and the end of the telescopic cover plate 21 away from the fixed plate 20 is connected to the inner wall of the drying box 1.

[0056] The 匚-shaped bracket 22 is symmetrically installed at the bottom of the fog nozzle 15, and the rotating wheel 23 is rotatably installed on the 匚-shaped bracket 22 through a bearing, and the rotating wheel 23 follows the 匚-shaped bracket 22 to move against the evaporative drying work plate 6. The fog nozzle 15 drives the 匚-shaped bracket 22 to move along the length direction of the evaporative drying work plate 6, ensuring that the fog nozzle 15 sprays the fermentation liquid steadily.

[0057] During the specific implementation process, when the electric push rod 17 drives the fog-making nozzle 15 to move downward, the U-shaped brackets 22 arranged at both ends of the fog-making nozzle 15 move downward synchronously until the runners 23 rotatably arranged at the bottom of the U-shaped brackets 22 abut against both ends of the evaporation and drying operation plate 6. At this time, the fog-making nozzle 15 stops moving downward. At the same time, the telescopic cover plates 21 are arranged at both ends of the fog-making nozzle 15. When the fog-making nozzle 15 moves downward, the telescopic cover plates 21 move downward synchronously until the telescopic cover plates 21 are located directly above the evaporation and drying operation plate 6, covering the upper opening of the evaporation and drying operation plate 6, so that a sealed cavity is formed between the evaporation and drying operation plate 6 and the telescopic cover plates 21. At this time, when the fog-making nozzle 15 sprays the broccoli fermentation product liquid in the sealed cavity, the broccoli fermentation product liquid will not leak, and at the same time, the broccoli fermentation product liquid can be restricted on the surface of the evaporation and drying operation plate 6, avoiding unnecessary loss of the broccoli fermentation product liquid.

[0058] Refer to Figure 6 and Figure 7 As shown, which is the structural schematic diagram of the telescopic structure of the telescopic cover plate 21 described above; specifically, the telescopic cover plate 21 includes a first telescopic cover plate 210, a second telescopic cover plate 211, a third telescopic cover plate 212, and a fixed cover plate 213. The fixed cover plates 213 are symmetrically arranged on both sides in the length direction of the drying box 1. The first telescopic cover plate 210, the second telescopic cover plate 211, and the third telescopic cover plate 212 are sequentially slidably installed inside the fixed cover plate 213 along the width direction of the fixed cover plate 213. The first telescopic cover plate 210 is connected to the fixing plates 20 on both sides of the fog-making nozzle 15.

[0059] It should be noted that the telescopic cover plates 21 are symmetrically arranged at both ends of the fog-making nozzle 15, and the telescopic cover plates 21 are mutually clamped with the fixing plates 20 at both ends of the fog-making nozzle 15; secondly, the telescopic cover plates 21 can slide up and down along the inner wall of the drying box 1.

[0060] The first telescopic cover plate 210, the second telescopic cover plate 211, the third telescopic cover plate 212, and the fixed cover plate 213 need to be contracted in sequence every time. After the entire telescopic cover plate 21 is extended, first the third telescopic cover plate 212 contracts, then the second telescopic cover plate 211, and then the first telescopic cover plate 210 contracts; secondly, when the telescopic cover plate 21 is extended, there is no external force restricting its telescopic sequence. Only when the telescopic cover plate 21 contracts does it need to be contracted in sequence, and the purpose is to realize automatic cleaning of the bottom of the telescopic cover plate 21.

[0061] During the specific implementation process, when the fog-making nozzle 15 moves left and right along the length direction of the drying box 1, the telescopic shielding plate 21 on one side extends, and the telescopic shielding plate 21 on the other side contracts, ensuring that the telescopic shielding plate 21 can always cover directly above the entire evaporation drying operation plate 6 when the fog-making nozzle 15 sprays the broccoli fermentation product liquid.

[0062] Because when the broccoli fermentation product liquid evaporates on the evaporation drying operation plate 6, the telescopic shielding plate 21 can protect the broccoli fermentation product liquid during the evaporation process, preventing the bubbles generated during evaporation from driving the broccoli fermentation product liquid to splash when they burst.

[0063] When the fog-making nozzle 15 moves along the length direction of the evaporation drying operation plate 6, the broccoli fermentation product liquid can be sprayed onto the evaporation drying operation plate 6, and it is evaporated and dried by the evaporation drying operation plate 6. After the fog-making nozzle 15 finishes evaporating the broccoli fermentation product liquid on the upper surface of the evaporation drying operation plate 6, the fog-making nozzle 15 moves upward, so that the fog-making nozzle 15 and the telescopic shielding plate 21 are away from the evaporation drying operation plate 6. A driving motor 18 is also provided at the side end of the drying box 1 through a motor seat, and the output end of the driving motor 18 controls the evaporation drying operation plate 6 to perform intermittent movement.

[0064] After the evaporation drying operation plate 6 loses the extrusion of the fog-making nozzle 15, ensure that the evaporation drying operation plate 6 has enough space to rotate. Then the driving motor 18 is started, and the driving motor 18 drives the evaporation drying operation plate 6 to perform an intermittent rotation of 180 degrees, so that the surface adhered with the solidified broccoli fermentation product liquid rotates to the bottom of the drying box 1, and the other side of the evaporation drying operation plate 6 rotates to the uppermost end. At this time, the fog-making nozzle 15 continues to move downward, and the fog-making nozzle 15 sprays the broccoli fermentation product liquid onto the other surface of the evaporation drying operation plate 6 and evaporates and dries it.

[0065] And the broccoli fermentation product that has completed the solidification of the broccoli fermentation product liquid and is located at the bottom of the evaporation drying operation plate 6 is discharged through the feeding assembly 3, ensuring that the fog-making nozzle 15 sprays the broccoli fermentation product liquid on one side of the evaporation drying operation plate 6, while the other end of the evaporation drying operation plate 6 cleans and collects the solidified broccoli fermentation product liquid; specifically as follows: Refer to Figure 9 、 Figure 10 and Figure 11As shown in the figure, a blanking assembly 3 for blanking the solid product formed after evaporative drying of the fermentation broth is further provided on the evaporation drying operation plate 6. The blanking assembly 3 includes guide posts 30, a first blanking scraper 31 and a second blanking scraper 32. The guide posts 30 are symmetrically arranged on both sides of the evaporation drying operation plate 6 along the width direction of the evaporation drying operation plate 6. The first blanking scraper 31 and the second blanking scraper 32 are slidably installed on the guide posts 30, and the middle parts of the first blanking scraper 31 and the second blanking scraper 32 are both attached to the area on the evaporation drying operation plate 6 where the fermentation broth is dried. The first blanking scraper 31 and the second blanking scraper 32 are always staggeredly distributed on the evaporation drying operation plate 6.

[0066] The blanking assembly 3 further includes an active connection block 33 and a passive connection block 34.

[0067] A number of active connection blocks 33 are all arranged on the C-shaped bracket 22. The passive connection block 34 is installed on the first blanking scraper 31 and the second blanking scraper 32. A plugging groove for plugging and installing the active connection block 33 is opened on the passive connection block 34.

[0068] It should be noted that the moving distance of the fog-making nozzle 15 is certain, and the active connection block 33 on the C-shaped bracket 22 can be inserted into the passive connection blocks 34 on the first blanking scraper 31 and the second blanking scraper 32.

[0069] In the specific implementation process, the fog-making nozzle 15 moves downward. At the same time, the passive connection blocks 34 on the C-shaped brackets 22 on both sides of it are inserted into the plugging grooves of the passive connection blocks 34 on the first blanking scraper 31. At this time, the fog-making nozzle 15 and the first blanking scraper 31 can move simultaneously. When the fog-making nozzle 15 moves from left to right along the length direction of the evaporation drying operation plate 6, the fog-making nozzle 15 sprays the broccoli fermentation product liquid on the upper end of the evaporation drying operation plate 6. At the same time, the first blanking scraper 31 also moves from left to right synchronously, so that the first blanking scraper 31 scrapes off the broccoli fermentation product liquid adhered and solidified at the lower end of the evaporation drying operation plate 6 from left to right in turn. The scraped solidified broccoli fermentation product will enter the bottom of the drying box 1, and then it can be collected uniformly.

[0070] After the solidified broccoli fermentation product at the bottom of the evaporation drying operation plate 6 is removed, the broccoli fermentation product liquid just sprayed on the upper end of the evaporation drying operation plate 6 will gradually solidify. After it solidifies, the evaporation drying operation plate 6 rotates intermittently by 180 degrees again, so that the end of the evaporation drying operation plate 6 containing the solidified broccoli fermentation product rotates to the bottom, and the end of the evaporation drying operation plate 6 that has been removed by the first blanking scraper 31 rotates to the top. Then, the broccoli fermentation product liquid is sprayed on the top of the evaporation drying operation plate 6, and the solidified broccoli fermentation product on the top of the evaporation drying operation plate 6 is removed.

[0071] Finally, according to the above steps, repeat the evaporation and scraping of the broccoli fermentation product liquid on the two end faces of the evaporation drying operation plate 6 to realize the cyclic processing of the broccoli fermentation product liquid, greatly improving the evaporation separation and drying efficiency of the broccoli seed fermentation product liquid in a low-pressure environment.

[0072] Moreover, through the cooperation of the first blanking scraper 31 and the second blanking scraper 32, it is possible to reciprocally scrape the rotatable evaporation drying operation plate 6, preventing the solidified broccoli fermentation product from remaining on the evaporation drying operation plate 6 and affecting the subsequent drying of the broccoli fermentation product liquid.

[0073] Embodiment 2: Refer to Figure 6 、 Figure 7 and Figure 8 As shown, on the basis of Embodiment 1, in order to further improve the evaporation drying efficiency of the broccoli fermentation product liquid in the present application, the present invention can also control the telescopic sequence of the telescopic cover plate 21, facilitating the automatic cleaning and scraping of the bottom of the telescopic cover plate 21, avoiding manual secondary cleaning, and greatly improving the service life of the entire equipment in the present application; specifically, one-way pawls 51 are hinged and installed on both the first telescopic cover plate 210 and the second telescopic cover plate 211 through torsion springs, and one-way racks 52 meshing with the one-way pawls 51 are installed on the inner side walls of the second telescopic cover plate 211 and the third telescopic cover plate 212. A return spring 50 is connected between one end of the third telescopic cover plate 212 close to the fixed cover plate 213 and the fixed cover plate 213.

[0074] Waste scraping blades 40 are provided at the bottoms of the second telescopic cover plate 211, the third telescopic cover plate 212, and the fixed cover plate 213, and the tops of the waste scraping blades 40 sequentially abut against the bottoms of the first telescopic cover plate 210, the second telescopic cover plate 211, and the third telescopic cover plate 212.

[0075] It should be noted that regarding the position of the collection plate 41, when the telescopic cover plate 21 moves up and down, the collection plate 41 does not affect the C-shaped bracket 22 from abutting against the evaporation drying operation plate 6. The collection plate 41 moves up and down synchronously with the telescopic cover plate 21.

[0076] A first spring telescopic plate 53 and a second spring telescopic plate 54 are installed on the fixed cover plate 213, and the ends of the one-way pawls 51 on the first telescopic cover plate 210 and the second telescopic cover plate 211 are respectively in the same straight line as the first spring telescopic plate 53 and the second spring telescopic plate 54.

[0077] It should be noted that the first spring telescopic plate 53 and the second spring telescopic plate 54 can be telescoped. After the first spring telescopic plate 53 abuts against the tail end of the one-way pawl 51 on the second telescopic cover plate 211, it can always exert pressure on its tail end, causing the corresponding one-way pawl 51 to rotate and separate from the corresponding one-way rack 52. Similarly, the second spring telescopic plate 54 has the same principle as the first spring telescopic plate 53.

[0078] Through the cooperation of the one-way pawl 51, the one-way rack 52, the first spring telescopic plate 53 and the second spring telescopic plate 54, it can always ensure that the telescopic cover plates 21 at both ends of the fog-making nozzle 15 contract in sequence, and at the same time, it is convenient to automatically clean the bottom of the telescopic cover plate 21.

[0079] In the specific implementation process, when the fog-making nozzle 15 sprays the broccoli fermentation product liquid along the length direction of the evaporation drying operation plate 6, the telescopic cover plate 21 on one side of the fog-making nozzle 15 is compressed, and the telescopic cover plate 21 on the other side is stretched. Specifically.

[0080] When the telescopic cover plate 21 is compressed, first, since there is no limit of the one-way rack 52 and the one-way pawl 51 on the third telescopic cover plate 212, the third telescopic cover plate 212 first moves towards the fixed cover plate 213. While the third telescopic cover plate 212 moves towards the fixed cover plate 213, a waste scraping knife 40 is provided at the bottom of the fixed cover plate 213. The waste scraping knife 40 scrapes the bottom of the third telescopic cover plate 212 to remove the solidified waste at the bottom of the third telescopic cover plate 212. Subsequently, the scraped waste falls into the collection plate 41 for collection.

[0081] Then, after the third telescopic cover plate 212 retracts into the fixed cover plate 213, the tail end of the one-way pawl 51 on the second telescopic cover plate 211 abuts against the first spring telescopic plate 53. The first spring telescopic plate 53 squeezes the one-way pawl 51 on the second telescopic cover plate 211, causing the one-way pawl 51 on the second telescopic cover plate 211 to separate from the one-way rack 52 on the third telescopic cover plate 212. At this time, the second telescopic cover plate 211 can contract into the third telescopic cover plate 212. Similarly, the waste scraping knife 40 at the bottom of the third telescopic cover plate 212 scrapes the bottom of the second telescopic cover plate 211 to remove the waste at the bottom of the second telescopic cover plate 211. Subsequently, the scraped waste falls into the collection plate 41 for collection.

[0082] Then, after the second telescopic cover plate 211 retracts into the third telescopic cover plate 212, the tail end of the one-way pawl 51 on the first telescopic cover plate 210 abuts against the second spring telescopic plate 54, and the one-way pawl 51 on the first telescopic cover plate 210 is squeezed by the second spring telescopic plate 54, so that the one-way pawl 51 on the first telescopic cover plate 210 is separated from the one-way rack 52 on the second telescopic cover plate 211. Subsequently, the first telescopic cover plate 210 can contract into the second telescopic cover plate 211. Then, repeat the above steps to remove the waste at the bottom of the first telescopic cover plate 210 with the waste shovel 40.

[0083] Finally, as the fog-making nozzle 15 moves, the bottom of the telescopic cover plate 21 on both sides of the fog-making nozzle 15 can be automatically cleaned in a linkage manner, and the waste cleaned can be recycled and reused.

[0084] During operation: In the first step, when it is necessary to evaporate and dry the broccoli seed fermentation product liquid, first prepare the broccoli seed fermentation liquid in advance, and then fill the broccoli seed fermentation product liquid into the storage tank 13 specifically used for storing the broccoli seed fermentation product liquid, and it is necessary to ensure the tightness of the broccoli seed fermentation product liquid.

[0085] In the second step: After the entire equipment is inspected, the inside of the drying box 1 starts to perform a vacuum operation, so that the inside of the entire drying box 1 is in a vacuum and low-pressure environment. Then, the electric push rod 17 drives the fog-making nozzle 15 to move downward until the fog-making nozzle 15 abuts against the evaporation and drying operation plate 6. Subsequently, the valve of the storage tank 13 is opened, so that the broccoli seed fermentation product liquid is transported into the inside of the drying box 1 through the conveying pipeline 14. Then, the broccoli seed fermentation product liquid enters the fog-making nozzle 15 through the conveying pipeline 14, and the broccoli seed fermentation product liquid is sprayed onto the area for evaporating the broccoli seed fermentation product liquid on the evaporation and drying operation plate 6 inside the drying box 1 through the fog-making nozzle 15. Then, the water in the broccoli seed fermentation product liquid starts to evaporate after contacting the evaporation and drying operation plate 6, and is gradually dried.

[0086] In the third step: When the fog-making nozzle 15 starts to spray the broccoli seed fermentation product liquid downward, the broccoli seed fermentation product liquid will contact the evaporation and drying operation plate 6. At the same time, the electric slide rail 42 drives the fog-making nozzle 15 to move along the length direction of the drying box 1 through the electric slider 43. As the fog-making nozzle 15 moves, the fog-making nozzle 15 evenly sprays the broccoli seed fermentation product liquid onto the entire upper surface of the evaporation and drying operation plate 6. After the evaporation and drying operation plate 6 continuously heats the broccoli seed fermentation product liquid at a low temperature, the water in the broccoli seed fermentation product liquid is evaporated until the broccoli seed fermentation product liquid changes from a liquid to a solid state, and a rectangular structure of the broccoli seed fermentation product is formed on the upper surface of the evaporation and drying operation plate 6.

[0087] Step 4: Subsequently, the driving motor 18 is started, and the driving motor 18 drives the evaporation drying operation plate 6 to perform intermittent rotation of 180 degrees, so that the surface adhered with the solidified broccoli fermentation product rotates to the bottom of the drying box 1, while the other side of the evaporation drying operation plate 6 rotates to the uppermost end. At this time, the fog-making nozzle 15 continues to move downward, and the fog-making nozzle 15 sprays the broccoli fermentation product liquid onto the other side of the evaporation drying operation plate 6 and performs evaporation drying on it.

[0088] Step 5: At the same time, when the fog-making nozzle 15 sprays the broccoli fermentation product liquid onto the upper end of the evaporation drying operation plate 6 along the length direction of the evaporation drying operation plate 6, the first blanking scraper 31 also moves synchronously, so that the first blanking scraper 31 scrapes off the solidified broccoli fermentation product liquid adhered to the lower end of the evaporation drying operation plate 6 from left to right in sequence, and the scraped solidified broccoli fermentation product will enter the bottom of the drying box 1, and then it can be uniformly collected.
