Description

Technical Field

[0001] This utility model relates to the field of food drying technology, specifically to a high-efficiency tremella dehydration device based on vacuum freeze-drying technology. Background Technology

[0002] Tremella is an edible fungus with high nutritional value and unique taste, and it is widely used in the food and health product industries. However, due to the high water content of fresh tremella, it is difficult to preserve and is prone to spoilage. In order to extend its shelf life, the commonly used dehydration methods include natural sun drying, hot air drying, microwave drying and vacuum freeze drying.

[0003] Vacuum freeze-drying can effectively preserve the nutrients, color, and flavor of white fungus. However, this process is usually time-consuming, energy-intensive, and requires significant equipment investment and technical expertise. To address these issues and improve economic efficiency, optimizing the drying process is crucial for enhancing overall effectiveness. One effective method is to pre-treat the white fungus by removing excess water before it enters the main dryer, thereby reducing the moisture content in subsequent drying steps and lowering the overall energy consumption. However, traditional centrifugal dehydration equipment often uses fixed speed and centrifugal force settings, which limits the possibility of flexible adjustments based on different material characteristics and specific dehydration requirements. Therefore, we propose a high-efficiency white fungus dehydration device based on vacuum freeze-drying technology. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a high-efficiency tremella dehydration device based on vacuum freeze-drying technology.

[0005] The technical solution is as follows: A high-efficiency tremella dehydration device based on vacuum freeze-drying technology, comprising a water collection cylinder and a cover, wherein the water collection cylinder is the carrier of the dehydration device, the top of the water collection cylinder is open, and the cover is disposed at the opening at the top of the water collection cylinder; further comprising: a motor, fixedly installed at the inner bottom of the water collection cylinder; a dehydration cylinder, disposed inside the water collection cylinder, the dehydration cylinder being a cylindrical cylinder with a discharge port at its top; a connecting block, fixedly connected to the output shaft of the motor; a guide rail, fixedly disposed at the outer bottom of the dehydration cylinder, the connecting block and the guide rail being slidably connected; and a second motor, fixedly installed at the dehydration cylinder. On the bottom surface of the cylinder, the second motor drives the dehydration cylinder to rotate through the connecting block; the lead screw is installed on the output shaft of the second motor, the lead screw passes through the connecting block and is threadedly matched with it, the second motor drives the lead screw to rotate, the connecting block reacts on the lead screw through the thread, causing the lead screw, the second motor and the dehydration cylinder to be displaced under the guidance of the guide rail, thereby changing the driving position between the dehydration cylinder and the connecting block, and causing the rotation center of the dehydration cylinder driven by the first motor through the connecting block to shift, thereby changing the centrifugal force when the dehydration cylinder rotates for dehydration, so as to adapt to the centrifugal force requirements when dehydrating tremella in different states.

[0006] Furthermore, there is a certain water collection space between the water collection cylinder and the dehydration cylinder. The dehydration cylinder has densely packed dehydration holes around its circumference. A drain port is connected to the lower side wall of the water collection cylinder. The drain port is used to connect to an external drain pipe. The water in the tremella inside the rotating dehydration cylinder will be thrown onto the inner wall of the water collection cylinder through the dehydration holes under the action of centrifugal force, and finally transported to the external drain pipe through the drain port for safe discharge.

[0007] Furthermore, it also includes a base, support plates, hinge frames, and a buffer tilting mechanism. The base is located below the water collection cylinder. Two support plates are symmetrically fixed to the top surface of the base. Hinges are rotatably mounted on both support plates. The hinge frames are symmetrically fixed to the outer walls on both sides of the water collection cylinder. The base is also equipped with a buffer tilting mechanism to buffer the vibration generated during the eccentric rotation of the water collection cylinder and the dewatering cylinder during dewatering. The buffer tilting mechanism can also tilt the water collection cylinder and the dewatering cylinder to discharge material.

[0008] Furthermore, the buffer tilting mechanism includes: gears, symmetrically fixedly mounted on the rotating shafts of two hinge frames; two electric slide rails, symmetrically fixed on both sides of the top surface of the machine base, with the two electric slide rails distributed on both sides of the water collection cylinder; sliding plates, slidably mounted on each of the electric slide rails; guide rod frames, mounted on the upper end of each of the sliding plates; and racks, fixed on the top of the guide rod frames, with the racks meshing with the corresponding gears on the same side. The electric slide rails on both sides simultaneously drive the sliding plates and the racks on the guide rod frames to move, and the moving racks mesh with the corresponding gears, causing the hinge frames on both sides to synchronously drive the water collection cylinder to tilt and rotate, thereby facilitating the user to discharge the dehydrated silver ear fungus.

[0009] Furthermore, the guide rod frame consists of a guide rod and a connecting rod. The guide rod slides through the corresponding sliding plate on the same side. A spring is provided between the sliding plate and the guide rod frame. The spring is used to provide buffering between the sliding plate and the guide rod frame, preventing the electric slide rail from rigidly driving the guide rod frame through the sliding plate. This ensures that the vibration generated by the dewatering cylinder inside the water collecting cylinder during eccentric spiral dewatering cannot be directly transmitted to the electric slide rail through the hinge frame, but is buffered by the spring, thereby improving the service life of the electric slide rail.

[0010] Furthermore, the external seal of the first motor is provided with a protective shell, and the external seal of the second motor is also provided with a protective shell. A protective shell is installed on the outer wall of the two support plates. The protective shell protects the gear and rack, preventing the gear and rack transmission structure from being directly exposed to the outside and causing personal safety risks, thereby improving the overall safety of the dehydration device.

[0011] This utility model has the following advantages:

[0012] 1. This utility model uses a motor to drive the dehydration cylinder to rotate, and the rotation center can be adjusted to change the magnitude of centrifugal force. It automatically adjusts the optimal dehydration conditions according to the different states of the white fungus, thereby improving dehydration efficiency and quality. At the same time, the compartment design between the water collection cylinder and the dehydration cylinder, as well as the dense configuration of dehydration holes and the design of the drainage interface, ensure the effective separation and discharge of water, thereby improving the drying effect on the white fungus.

[0013] 2. This utility model adopts a support system composed of a base, support plate and hinge frame, plus a buffer tilting mechanism, which not only ensures the stability of the equipment during operation, but also facilitates the unloading operation of the final product. The spring between the sliding plate and the guide rod frame absorbs the vibration generated during the operation of the equipment, thus extending the service life of the equipment.

[0014] 3. This utility model can also reduce safety hazards during operation and ensure the safety of workers to a certain extent by setting protective shells for key components such as motors and protecting the gear and rack transmission parts. Attached Figure Description

Detailed Implementation

[0020] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] A high-efficiency dehydration device for tremella based on vacuum freeze-drying technology, such as Figures 1-4As shown, the device includes a water collecting cylinder 1 and a cover 2. The water collecting cylinder 1 serves as the carrier of this dewatering device, with an opening at the top. The cover 2 is located at the opening at the top of the water collecting cylinder. It also includes: a motor 4, fixedly installed at the bottom inner part of the water collecting cylinder 1; a dewatering cylinder 5, located inside the water collecting cylinder 1, which is a cylindrical cylinder with a discharge port at its top; a connecting block 6, fixedly connected to the output shaft of the motor 4; a guide rail 7, fixedly installed at the bottom outer part of the dewatering cylinder 5, with the connecting block 6 and the guide rail 7 slidably connected; a second motor 9, fixedly installed on the bottom surface of the dewatering cylinder 5, which drives the dewatering cylinder 5 to rotate via the connecting block 6; and a lead screw 8, installed on the output shaft of the second motor 9, which passes through the connecting block 6 and is threadedly fitted to it. The second motor 9 drives the lead screw 8 to rotate, and the connecting block 6 reacts to the lead screw 8 through its threads. The screw 8, motor 9, and dehydration cylinder 5 are displaced under the guidance of the guide rail 7. This changes the driving position between the dehydration cylinder 5 and the connecting block 6, and causes the motor 4 to drive the rotation center of the dehydration cylinder 5 to shift through the connecting block 6. This changes the centrifugal force during the dehydration of the dehydration cylinder 5, adapting to the centrifugal force requirements of dehydrating tremella in different states. There is a certain water collection space between the water collection cylinder 1 and the dehydration cylinder 5. The cylinder wall of the dehydration cylinder 5 has densely packed dehydration holes 51. The drain port 3 is connected to the lower side wall of the water collection cylinder 1 and is used to connect to an external drain pipe. The water in the tremella inside the rotating dehydration cylinder 5 will be thrown onto the inner wall of the water collection cylinder 1 through the dehydration holes 51 under the action of centrifugal force, and finally transported to the external drain pipe through the drain port 3 for safe discharge.

[0022] like Figure 1 and Figure 4 As shown, it also includes a base 10, a support plate 101, a hinge frame 11, and a buffer tilting mechanism. The base 10 is located below the water collection cylinder 1. Two support plates 101 are symmetrically fixed to the top surface of the base 10. A hinge frame 11 is rotatably installed on both support plates 101. The hinge frames 11 are symmetrically fixed to the outer walls on both sides of the water collection cylinder 1. The base 10 is also provided with a buffer tilting mechanism to buffer the vibration generated when the water collection cylinder 1 and the dewatering cylinder 5 rotate eccentrically for dewatering. The buffer tilting mechanism can also tilt the water collection cylinder 1 and the dewatering cylinder 5 to discharge materials.

[0023] like Figure 1 and Figure 4As shown, the buffer tilting mechanism includes: gears 12, symmetrically fixedly installed on the rotating shafts of two hinge frames 11; electric slide rails 14, two of which are symmetrically fixed on both sides of the top surface of the base 10, with the two electric slide rails 14 distributed on both sides of the water collection cylinder 1; sliding plates 15, slidably mounted on each electric slide rail 14; guide rod frames 151, installed on the upper end of each sliding plate 15; and racks 13, fixed on the top of the guide rod frames 151. The racks 13 and the corresponding gears 12 on the same side mesh with each other. The electric slide rails 14 on both sides simultaneously drive the sliding plates 15 and the racks 13 on the guide rod frames 151 to move. The moving racks 13 mesh with the corresponding gears 12, causing the hinge frames 11 on both sides to synchronously drive the water collection cylinder 1 to tilt and rotate, thus facilitating the user to discharge the dried and dehydrated tremella.

[0024] like Figure 4 As shown, the guide rod frame 151 consists of a guide rod and a connecting rod. The guide rod of the guide rod frame 151 slides through the corresponding sliding plate 15 on the same side. A spring 152 is provided between the sliding plate 15 and the guide rod frame 151. The spring 152 is used to provide buffer between the sliding plate 15 and the guide rod frame 151, so as to prevent the electric slide rail 14 from rigidly driving the guide rod frame 151 through the sliding plate 15. This prevents the vibration generated by the dewatering cylinder 5 inside the water collecting cylinder 1 during eccentric spiral dewatering from being directly transmitted to the electric slide rail 14 through the hinge frame 11. Instead, the vibration is buffered by the spring 152, thereby improving the service life of the electric slide rail 14.

[0025] like Figure 3 and Figure 4 As shown, the external seal of motor 4 is provided with a protective shell 16, and the external seal of motor 9 is also provided with a protective shell 2 17 to provide protection. Protective shell 3 18 is installed on the outer wall of the two support plates 101. The protective shell 3 18 protects the gear 12 and rack 13, avoiding the direct exposure of the transmission structure of gear 12 and rack 13 to the outside, thus avoiding personal safety risks and improving the overall safety of the dehydration device.

[0026] When using this device to dry tremella before vacuum freeze-drying, firstly, place the tremella to be dehydrated into the dehydration cylinder 5, filling it through the discharge port at the top of the dehydration cylinder 5. After the tremella is filled, cover 2 to ensure a relatively sealed environment inside the water collection cylinder 1. Next, start the device; motor 4 and motor 9 will begin operation. When motor 9 drives the lead screw 8 to rotate, the threaded action between the lead screw 8 and the connecting block 6 causes the entire dehydration cylinder 5, along with motor 9, to shift along the guide rail 7. This shift changes the rotation center of the dehydration cylinder 5, causing the centrifugal force on the tremella during dehydration to change. This allows for adjustment of the optimal dehydration effect based on the different states of the tremella. When the dehydration cylinder 5 inside the water collection cylinder 1 is adjusted to a suitable eccentric position, motor 4 is activated. The output of motor 4 drives the dehydration cylinder 5 to rotate through the connecting block 6. Under the action of centrifugal force, the tremella is pushed against the inner wall of the dehydration cylinder 5, and the water is released through... The water is ejected from the densely packed dehydration holes 51 on the wall of the dehydration cylinder 5 and finally falls onto the inner wall of the water collection cylinder 1. This water then flows along the inner wall of the water collection cylinder 1 to the drain port 3 and is discharged through the external drain pipe. When it is necessary to unload the silver ear fungus, the sliding plate 15 is moved by the electric slide rail 14. The sliding plate 15 then drives the rack 13 on the guide rod frame 151 to move. The rack 13 meshes with the gear 12, causing the hinge frame 11 to drive the water collection cylinder 1 to rotate and tilt, which facilitates the removal of the silver ear fungus material. At the same time, the spring 152 buffers the vibration and protects the electric slide rail 14 from the direct impact of the vibration transmitted by the water collection cylinder 1 and the dehydration cylinder 5 during dehydration. In addition, the protective shell 16 and the protective shell 2 17 protect the outside of the motor 4 and the motor 9 respectively, improving the normal use of the motor 4 and the motor 9 during dehydration. The protective shell 3 18 is equipped on the transmission parts of the gear 12 and the rack 13, thereby improving the operational safety and overall durability of the device.

[0027] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
