Description

Technical Field

[0001] This utility model relates to the field of dehydrated vegetable processing equipment, and in particular to a spin dryer for dehydrated vegetable processing. Background Technology

[0002] Dehydrated vegetables, also known as rehydrated vegetables, are dried vegetables made by washing and drying fresh vegetables to remove most of their water content. In the process of making dehydrated vegetables into food, the vegetables are usually washed and then spun dry. The spun-dry vegetables are then used for food processing. Currently, centrifugal spin dryers are mainly used for vegetable spun-drying operations and are widely used in food processing plants, agricultural bases, and supermarket supply chains. They are especially suitable for the pre-processing of dehydrated vegetables such as leafy vegetables (e.g., spinach, celery), root vegetables (e.g., carrots, potatoes), and cauliflower (e.g., broccoli, cauliflower).

[0003] In the dehydrated vegetable processing, the centrifuge is one of the key pieces of equipment. It uses the centrifugal force generated by high-speed rotation to remove water from the vegetables, shortening the drying time and reducing energy consumption. However, traditional single-layer screens have uniform mesh size. During dehydration, vegetables and water are mixed and spun out. Some water cannot be discharged due to the obstruction of vegetables, resulting in a high water residue rate. Furthermore, broken vegetables can easily clog the screen holes, reducing dehydration efficiency and affecting the quality of the finished product. Therefore, a centrifuge for dehydrated vegetable processing is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a spin dryer for dehydrated vegetable processing, which aims to improve the problem in the prior art that "the uniform aperture of a single-layer screen leads to some water not being able to be discharged due to the obstruction of vegetables, resulting in a high water residue rate".

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a spin dryer for dehydrating vegetables, comprising a base, a shell fixedly connected to the top of the base, a spin dryer cylinder disposed inside the shell, a sleeve fixedly connected inside the spin dryer cylinder, a fixing assembly disposed inside the shell, the fixing assembly comprising a rotating rod rotatably connected to the inner wall of the shell, the outer wall of the rotating rod fitting against the inner wall of the sleeve, a pull rod slidably connected to the inner wall of the rotating rod, a pull rope fixedly connected to the bottom of the pull rod, a limit rod fixedly connected to the end of the pull rope away from the pull rod, the limit rod slidably connected to the inner wall of the rotating rod, the limit rod being elastically connected to the inner wall of the rotating rod via a return spring, a limit hole disposed on the inner wall of the sleeve, the limit rod being inserted into the inner wall of the limit hole, and a drive assembly disposed on the top of the base.

[0006] As a further description of the above technical solution:

[0007] The central axis of the sleeve and the central axis of the spin dryer are aligned and vertically positioned.

[0008] As a further description of the above technical solution:

[0009] The spin dryer has an inner cylinder inside, and a through hole one is opened on the surface of the spin dryer, and a through hole two is opened on the surface of the inner cylinder.

[0010] As a further description of the above technical solution:

[0011] The diameter of the first through hole is smaller than that of the second through hole, and the spin-drying cylinder and the inner cylinder are manufactured as a single piece.

[0012] As a further description of the above technical solution:

[0013] The limiting rods are configured in multiple ways, and the multiple limiting rods are arranged in a ring at equal angular intervals inside the rotating rod. The sliding direction of the limiting rods is the radial direction of the rotating rod.

[0014] As a further description of the above technical solution:

[0015] The drive assembly includes a motor, which is fixedly connected to the top of the base, and a pulley is fixedly connected to the bottom of the motor's output shaft.

[0016] As a further description of the above technical solution:

[0017] The drive assembly also includes a second pulley, which is fixedly connected to the bottom of the rotating rod and is connected to the first pulley via a belt.

[0018] As a further description of the above technical solution:

[0019] A control panel is fixedly connected to the front of the housing, and a drain pipe is fixedly connected to the right side of the housing.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, by utilizing the difference in pore size between through hole one and through hole two, through hole one with a smaller pore size intercepts large particulate impurities, while through hole two with a larger pore size quickly discharges water, forming two stages of primary filtration and deep dehydration, thereby increasing the dehydration rate, reducing water residue, and improving the preparation efficiency of dehydrated vegetables.

[0022] 2. In this utility model, the one-piece molded spin-drying drum and the inner drum have no splicing gaps, reducing cleaning dead corners and preventing bacterial growth. With the quick-release fixing components, it is convenient to clean and replace. After the spin-drying drum is separated from the outer shell, it can be disassembled and cleaned independently, reducing downtime and improving equipment utilization. Attached Figure Description

Detailed Implementation

[0030] 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.

[0031] Reference Figure 1 - Figure 2 This utility model provides an embodiment of a dehydrated vegetable processing spin dryer, including a base 1, which serves as the basic support for the equipment. The outer shell 2 encloses and protects the internal components and integrates a control panel 14 for easy operation and monitoring. The top of the base 1 is fixedly connected to the outer shell 2, and the front of the outer shell 2 is fixedly connected to the control panel 14 for easy one-button start / stop and parameter setting. The right side of the outer shell 2 is fixedly connected to a drain pipe 15, and a manual valve is provided at the top of the drain pipe 15. A spin dryer 3 is provided inside the outer shell 2, and a sleeve 32 is fixedly connected inside the spin dryer 3. The central axis of the sleeve 32 and the central axis of the spin dryer 3 coincide and are set in a vertical state.

[0032] Reference Figure 2 and Figure 5 The spin dryer 3 has an inner cylinder 31 inside. The surface of the spin dryer 3 has through holes 33 for preliminary filtration of large particles of residue. The surface of the inner cylinder 31 has through holes 34 to allow water to drain quickly, forming a layered dehydration structure. The diameter of through hole 33 is smaller than that of through hole 34, forming two-stage drainage to avoid clogging by broken vegetables. The spin dryer 3 and the inner cylinder 31 are manufactured as a single piece, which enhances the overall strength and reduces cleaning dead corners. The outer shell 2 has a fixing component 10 inside.

[0033] Reference Figure 2 - Figure 4 The fixing component 10 includes a rotating rod 101, which is powered by a motor 111 to rotate, driving a limiting rod 104 to engage with a sleeve 32 to ensure stable rotation of the spin dryer 3. The rotating rod 101 is rotatably connected to the inner wall of the outer casing 2, and the outer wall of the rotating rod 101 is in contact with the inner wall of the sleeve 32. A pull rod 102 is slidably connected to the inner wall of the rotating rod 101, and a pull rope 103 is fixedly connected to the bottom of the pull rod 102. The pull rope 103 is non-elastic and can better transmit the pulling force. A limiting rod 104, which is cylindrical, is fixedly connected to the end of the pull rope 103 away from the pull rod 102. The limiting rod 104 is slidably connected to the inner wall of the rotating rod 101.

[0034] Reference Figure 3 - Figure 5 Multiple limiting rods 104 are provided, and the multiple limiting rods 104 are arranged in a ring at equal angles inside the rotating rod 101. The sliding direction of the limiting rods 104 is the radial direction of the rotating rod 101. Since the part of the limiting rod 104 located outside the rotating rod 101 is inserted into the limiting hole 106, the centrifugal force when the rotating rod 101 rotates will not cause the limiting rod 104 to fall out of the limiting hole 106. The limiting rod 104 is elastically connected to the inner wall of the rotating rod 101 through the return spring 105. By setting the return spring 105, an elastic force away from the center of the rotating rod 101 is applied to the limiting rod 104. The inner wall of the sleeve 32 is provided with the limiting hole 106. The limiting rod 104 is inserted into the inner wall of the limiting hole 106 to realize the limiting locking and release of the spin dryer 3. The top of the base 1 is provided with a drive assembly 11.

[0035] Reference Figure 2 and Figure 3 The drive assembly 11 includes a motor 111, which provides power to the rotating rod 101 to drive the spin dryer 3 to rotate at high speed and generate centrifugal force to accelerate dehydration. The motor 111 is fixedly connected to the top of the base 1. A pulley 112 is fixedly connected to the bottom of the output shaft of the motor 111. The drive assembly 11 also includes a pulley 113, which is fixedly connected to the bottom of the rotating rod 101. The pulley 113 is connected to the pulley 112 via a belt 114.

[0036] Working principle: During use, the operator starts the motor 111 through the control panel 14, which drives the pulley 112 to rotate. The belt 114 transmits power to the pulley 113, which drives the rotating rod 101 to rotate synchronously. When the rotating rod 101 rotates, the limiting rod 104 on its inner wall slides radially through the elastic force of the return spring 105 and inserts into the limiting hole 106 of the sleeve 32, ensuring that the spin-drying cylinder 3 and the rotating rod 101 rotate coaxially and avoid deviation. As the spin-drying cylinder 3 rotates at high speed, the vegetables inside are pressed tightly against the inner wall of the inner cylinder 31 by centrifugal force. The water is quickly discharged through the through hole 34, while the remaining coarse particles are intercepted by the through hole 33, reducing the risk of screen blockage. The water is discharged through the drain pipe 15 at the bottom of the outer shell 2.

[0037] After dehydration is complete, the motor 111 is stopped via the control panel 14. Then, the operator pulls the lever 102 upwards. The lever 102 moves and pulls all the limit rods 104 radially back and disengage from the limit hole 106 via the pull rope 103, thereby releasing the spin-drying cylinder 3. By pulling the spin-drying cylinder 3 upwards, the rotating rod 101 and the sleeve 32 are separated, making it easy to clean or replace the spin-drying cylinder 3 manually. When reinstalling the cylinder, simply align and insert it, and the limit rod 104 will automatically lock, reducing the time for cleaning and changing materials between batches. The speed of the motor 111 can be adjusted via the control panel 14 to adapt to the dehydration needs of different types of vegetables, achieving efficient and energy-saving operation.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
