Description

Technical Field

[0001] This utility model relates to the technical field of spirulina dehydration equipment, specifically a dehydration device for spirulina processing. Background Technology

[0002] Because spirulina has a very high natural water content (70%~90%), it is prone to spoilage and high cost when used directly. Therefore, it needs to be dehydrated during processing. Dehydration can reduce the water content to 5%~10%, which significantly inhibits the growth of microorganisms and extends the shelf life. At the same time, it concentrates nutrients such as protein and vitamins, increases the energy density of feed, and breaks down cell walls to promote animal digestion and absorption. In addition, dried spirulina is small in volume and light in weight, making it easy to transport and store, and it is also easier to mix evenly with other feeds to ensure a stable nutritional ratio.

[0003] In the prior art, such as the dehydration device for spirulina production and processing proposed in patent application number "CN202222416699.2", a guide component, a drying component located above the guide component, and a dehydration component slidably connected to the guide component are included. The dehydration frame is driven to move up and down by a drive mechanism to remove water from the spirulina. After the operation is completed, the drying component can be opened to perform further drying operations.

[0004] However, in the aforementioned patent application, when dehydrating spirulina, the dehydration frame needs to move the spirulina up and down. On the one hand, the dehydration frame is in a relatively open state, resulting in large heat loss and insufficient heating and dehydration efficiency. On the other hand, the up and down movement of the dehydration frame causes the spirulina inside to alternately move closer or further away from the heat source equipment, which can easily lead to residual moisture causing mold or bacterial growth. Utility Model Content

[0005] The purpose of this invention is to provide a dehydration device for spirulina processing to solve the problems mentioned in the background art.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A dehydration device for processing spirulina includes a support frame, with a sealing mechanism and a dehydration mechanism that can move up and down below the support frame.

[0008] The sealing mechanism includes a sealed top cover, which is fixed to the bottom of the support, and a rectangular frame is fixedly connected to the top of the sealed top cover. A hot air blower is installed on the rectangular frame.

[0009] The dehydration mechanism includes a support bracket located below the closed top cover. The top of the support bracket has a cavity for holding the spirulina to be dehydrated, and the bottom of the support bracket is equipped with a filter screen for filtering the spirulina.

[0010] Preferably, a drive motor is fixedly installed on one side of the closed top cover, and a rotating shaft is fixedly connected to the output end of the drive motor. A stirring rod is fixedly connected to the outer surface of the rotating shaft and located inside the closed top cover.

[0011] Preferably, a recycling bin is provided at the bottom of the support bracket for collecting water flowing down from the bottom of the support bracket.

[0012] Preferably, both ends of the closed top cover are fixedly connected to guide buckets, and both ends of the support bracket are fixedly connected to guide rods that cooperate with the guide buckets.

[0013] Preferably, the top of the bracket is provided with two retracting mechanisms. Each retracting mechanism includes a fixed plate fixed to the top of the bracket, a servo motor fixedly connected to one side of the fixed plate, a rotating rod fixedly connected to the output end of the servo motor, and two retracting wheels fixedly connected to the rotating rod.

[0014] The first connecting rope and the second connecting rope are fixedly connected to the retracting wheels of the two retracting mechanisms, respectively. The first fixing part and the second fixing part are fixedly connected to both sides of the bearing bracket, respectively. The bottom of the first connecting rope passes through the bracket and is fixedly connected to the first fixing part.

[0015] Preferably, a hydraulic cylinder is fixedly installed on the top of the bracket, and a four-end connecting plate is fixedly connected to the telescopic end of the hydraulic cylinder.

Simultaneously, the distance between the support bracket holding the spirulina and the hot air blower remains constant during heating, ensuring more thorough and uniform dehydration of the spirulina and preventing residual moisture from causing mold or bacterial growth, thus affecting product safety. After dehydration, the support bracket can be tilted to one side for easy placement and removal of the spirulina. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figure 1 A dehydration device for spirulina processing. Spirulina is closely related to agricultural and rural development. Its high protein content can be used as a high-quality feed additive to improve the efficiency of animal husbandry and animal health. In ecological agriculture, spirulina can be cultivated on a large scale using wastewater and waste gas to promote resource recycling. Therefore, spirulina cultivation and processing are carried out in agriculture and rural areas. Spirulina dehydration is one of the steps in spirulina processing.

[0028] It includes a support 100, the bottom of which is supported by four support legs. A closing mechanism 1 and a vertically movable dehydration mechanism 2 are provided below the support 100. The closing mechanism 1 is located above the dehydration mechanism 2.

[0029] like Figure 1 , Figure 4 and Figure 5 The sealing mechanism 1 includes a sealing top cover 101, which is fixed to the bottom of the support 100. A rectangular frame 102 is fixedly connected to the top of the sealing top cover 101. A hot air blower 103 is installed on the rectangular frame 102. The hot air blower 103 is connected to an external power supply and has a corresponding external control switch. The bottom of the sealing top cover 101 is an arc-shaped cavity, and there is a partition net at the connection between the sealing top cover 101 and the rectangular frame 102, so that hot air inside the rectangular frame 102 can enter the interior of the sealing top cover 101 while preventing spirulina from entering the rectangular frame 102.

[0030] like Figure 1 , Figure 4 and Figure 5 The dehydration mechanism 2 includes a support bracket 201, which is located below the closed top cover 101. The top of the support bracket 201 has a flexible protective layer to reduce the impact force generated when the support bracket 201 and the closed top cover 101 come into contact. The top of the support bracket 201 has a cavity for accommodating the spirulina to be dehydrated. The bottom of the support bracket 201 is provided with a water filter screen 202 for filtering the spirulina.

[0031] like Figure 1 , Figure 4 and Figure 5 A drive motor 3 is fixedly installed on one side of the closed top cover 101. The drive motor 3 is connected to an external power source and has a corresponding control switch. The output end of the drive motor 3 is fixedly connected to a rotating shaft 4. A stirring rod 5 is fixedly connected to the outer surface of the rotating shaft 4 and located inside the closed top cover 101. The bottom of the closed top cover 101 and the top of the support bracket 201 both have arc-shaped openings, so that when the support bracket 201 and the closed top cover 101 are fitted together, the rotation of the rotating shaft 4 is not affected.

[0032] like Figure 4 and Figure 5 The bottom of the support bracket 201 is provided with a recycling box 6, which is used to collect water flowing down from the bottom of the support bracket 201. Water filtered out inside the support bracket 201 can drip into the inside of the recycling box 6.

[0033] like Figure 4 and Figure 5Both ends of the closed top cover 101 are fixedly connected to guide buckets 7, and both ends of the support bracket 201 are fixedly connected to guide rods 8 that cooperate with the guide buckets 7. The inner side of the guide bucket 7 is an arc surface. When the top of the guide rod 8 extends into the inside of the guide bucket 7, it can guide the movement under the arc surface inside the guide bucket 7 and drive the support bracket 201 to move, so that the support bracket 201 and the closed top cover 101 can be aligned together.

[0034] like Figure 1-5 The top of the bracket 100 is provided with two take-up and release mechanisms. Each take-up and release mechanism includes a fixed plate 9 fixed to the top of the bracket 100. A servo motor 10 is fixedly connected to one side of the fixed plate 9. A rotating rod 11 is fixedly connected to the output end of the servo motor 10. The servo motor 10 is connected to an external power source and can drive the rotating rod 11 to rotate in different directions. Two take-up and release wheels 12 are fixedly connected to the rotating rod 11. The take-up and release wheels 12 can wind or release the first connecting rope 13 and the second connecting rope 14 connected to them. The servo motors 10 on the two take-up and release mechanisms are controlled independently.

[0035] like Figure 1-5 The first connecting rope 13 and the second connecting rope 14 are fixedly connected to the two retracting and extending mechanisms respectively, which can drive one side of the bearing bracket 201 to move. The first fixing part 15 and the second fixing part 16 are fixedly connected to both sides of the bearing bracket 201 respectively. The bottom of the first connecting rope 13 passes through the bracket 100 and is fixedly connected to the first fixing part 15, so that the first connecting rope 13 can drive the other side of the bearing bracket 201 to move.

[0036] like Figure 1-5 A hydraulic cylinder 17 is fixedly installed on the top of the bracket 100. The hydraulic cylinder 17 is existing technology and is equipped with a power source. A four-end connecting plate 18 is fixedly connected to the telescopic end of the hydraulic cylinder 17. Guide wheels 19 are rotatably connected to the four ends of the four-end connecting plate 18. A fixed pulley 20 is fixedly connected to the bottom of the bracket 100. The second connecting rope 14 passes through the guide wheel 19 and the fixed pulley 20 and is fixedly connected to the second fixed part 16. The direction of movement of the second connecting rope 14 can be changed by using the guide wheel 19 and the fixed pulley 20.

[0037] The working principle of the dehydration device for spirulina processing provided by this utility model is as follows:

[0038] When spirulina needs to be added for processing and dehydration, or when spirulina needs to be removed after dehydration, the hydraulic cylinder 17 first retracts, driving the four-end connecting plate 18 and guide wheel 19 to move, and the second connecting rope 14 moves accordingly, causing the support bracket 201 connected to the bottom of the second connecting rope 14 to tilt to one side, making it easier to put in or take out spirulina. After putting in or taking out spirulina, the hydraulic cylinder 17 extends, driving the four-end connecting plate 18 and guide wheel 19 to move, and the second connecting rope 14 moves accordingly, so that the support bracket 201 returns to a horizontal state.

[0039] When dehydration is required, water is filtered through the filter screen 202. Then, two independent servo motors 10 drive the take-up and release wheels 12 to rotate, respectively winding the first connecting rope 13 and the second connecting rope 14, which drives the support bracket 201 to move upward and fit against the bottom of the closed top cover 101. The hot air blower 103 dries and dehydrates the spirulina. At the same time, the drive motor 3 drives the stirring rod 5 through the rotating shaft 4 to stir the spirulina, so that the spirulina can be dehydrated better. After dehydration is completed, the first connecting rope 13 and the second connecting rope 14 are released, and the support bracket 201 moves downward.

[0040] Compared with related technologies, the dehydration device for spirulina processing provided by this utility model has the following beneficial effects:

[0041] This invention, by moving the dehydration mechanism 2 upward, can form a relatively enclosed space between the support bracket 201 and the closed top cover 101, making the thermal efficiency of heating and dehydrating spirulina higher and increasing the dehydration speed of spirulina. At the same time, during the heating process, the distance between the support bracket 201 used to hold spirulina and the hot air blower 103 will not change relative to each other, ensuring more thorough and uniform dehydration of spirulina and avoiding residual moisture from causing mold or bacterial growth, which would affect product safety. After dehydration or when dehydration is complete, the support bracket 201 can be tilted to one side for easy placement and removal of spirulina.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
