DETAILED DESCRIPTION

Figures 1-3

[0023] A potato starch dehydration device comprises:

[0024] ​The heat preservation cylinder 1 is provided with an electric heating rod 2 arranged in an annular array at the bottom side of the heat preservation cylinder 1, and the heating end of the electric heating rod 2 extends to the inside of the heat preservation cylinder 1;

[0025] The heat conduction cylinder 3 is fixedly embedded in the middle of the bottom of the heat preservation cylinder 1, the inside of the heat conduction cylinder 3 is provided with a material buffering plate 4, the bottom end of the heat conduction cylinder 3 is tapered, and the heat conduction cylinder 3 is provided with a discharge port 301, and the surface of the heat conduction cylinder 3 is provided with a first exhaust pipe 5 penetrating through the heat preservation cylinder 1;

[0026] The preheating cylinder 6 is embedded in the inside of the heat preservation cylinder 1, the bottom end of the preheating cylinder 6 is tapered and communicates with the heat conduction cylinder 3, and the side wall of the preheating cylinder 6 is provided with an inlet hopper 7;

[0027] The screening mechanism 8 is arranged in the inside of the preheating cylinder 6, and the screening mechanism 8 is used for screening the starch.

[0028] Work flow description:

[0029] First step, preheating stage:

[0030] The electric heating rod 2 is started to heat the heat preservation cylinder 1, and after the internal temperature rises to 40 DEG C, the starch (with water content less than 5%) is introduced into the preheating cylinder 6 through the inlet hopper 7, and is screened by the screening mechanism 8 under the action of the vibrating screen, and the coarse particles are intercepted, and the fine powder falls into the heat conduction cylinder 3.

[0031] Second step, dehydration stage:

[0032] The starch enters the heat conduction cylinder 3 through the tapered bottom end of the preheating cylinder 6, the material buffering plate 4 delays the falling speed, so that it is uniformly heated, the electric heating rod 2 continuously heats the heat preservation cylinder 1, the heat is efficiently conducted to the starch through the aluminum alloy material buffering plate 4, the water is evaporated into water vapor, and the water vapor is discharged along the first exhaust pipe 5,

[0033] Third step, discharging stage:

[0034] The dehydrated starch is discharged along the tapered bottom end discharge port 301 of the heat conduction cylinder 3, and the continuous production is completed without stopping operation.

[0035] The potato starch dehydration device realizes the integrated continuous operation of "feeding-dehydration-discharging" through the linkage of the preheating cylinder 6, the heat conduction cylinder 3 and the screening mechanism 8, adapts to the industrial large-scale production demand, reduces the waste of electric energy caused by frequent start and stop, improves the heat energy utilization rate, and prolongs the service life of the equipment through continuous operation and reduces the mechanical start and stop impact, and is suitable for modern starch processing industry.

[0036] As Figure 3As shown in the drawings, in some embodiments, the screening mechanism 8 includes a screen 801 slidingly embedded on the upper side of the heat-conducting cylinder 3, the upper surface of the screen 801 is uniformly distributed with slide rods 802, the upper end of the slide rods 802 slidingly penetrates the top wall of the preheating cylinder 6 and is connected with a mounting plate 803, a spring 804 is sleeved on the surface of the slide rods 802 above the preheating cylinder 6, and a vibration motor 805 is arranged on the top of the mounting plate 803. More specifically, after the starch enters the preheating cylinder 6 through the feeding hopper 7, it falls on the vibrating screen 801, and when the motor operates, it drives the mounting plate 803 to reciprocate along the slide rods 802, and the kinetic energy of the mounting plate 803 is transmitted to the screen 801 through the slide rods 802, so that the screen 801 makes high-frequency vibration up and down in the heat-conducting cylinder 3 (the frequency is synchronized with the motor). During the vibration process, when the acceleration of the screen 801 exceeds the gravity acceleration, the starch particles are temporarily thrown up and jump, forming a "jumping" screening, avoiding static jamming, and ensuring that the fine particle starch uniformly enters the heat-conducting cylinder 3 for dehydration.

[0037] As shown in the drawings, Figure 1 In some embodiments, the first exhaust pipe 5 is designed to be inclined upward, and more specifically, the first exhaust pipe 5 is designed to be inclined upward (usually at an angle of 30°-60° with the horizontal plane), which utilizes the difference between gravity and airflow direction to realize the separation of starch particles and water vapor. Water vapor naturally rises along the inclined direction of the exhaust pipe and is discharged due to its small density and fast flow rate, while the density of starch is much greater than that of water vapor, which tends to settle back into the heat-conducting cylinder 3 under the action of gravity rather than being carried into the first exhaust pipe 5 by the airflow.

[0038] As shown in the drawings, Figure 1 In some embodiments, the top side of the preheating cylinder 6 is annularly connected with the second exhaust pipe 9, and the ports of the first exhaust pipe 5 and the second exhaust pipe 9 are provided with dust screens. More specifically, the first exhaust pipe 5 is responsible for removing high-temperature water vapor (generated during the starch dehydration stage), while the second exhaust pipe 9 focuses on handling low-temperature moisture (generated during the preheating stage). The dust screen can prevent external dust and impurities (such as workshop dust, insects, etc.) from entering the interior of the equipment through the exhaust pipe, thereby polluting the starch or clogging the pipeline.

[0039] As shown in the drawings, Figure 3 In some embodiments, the material buffer plate 4 is in a spiral shape, and more specifically, the material buffer plate 4 is fixed in the form of a spiral metal strip on the inner wall of the heat-conducting cylinder 3, the spiral axis coincides with the central axis of the heat-conducting cylinder 3, forming a continuous spiral ramp. The spiral ramp prolongs the downward path of the starch, increases the residence time of the material in the heat-conducting cylinder 3, and ensures sufficient heat absorption and dehydration. The spiral structure converts the inner wall of the heat-conducting cylinder 3 into a "continuous heat transfer surface", which significantly improves the heat utilization rate compared with the traditional straight falling structure, and achieves better dehydration effect.

[0040] As shown in the drawings, Figure 3As shown, in some embodiments, the material buffer plate 4 is an aluminum alloy piece, more specifically, an aluminum alloy material, which has high heat transfer efficiency and can quickly conduct the heat of the electric heating rod 2 to the starch, thereby shortening the dehydration time, and the aluminum alloy material is relatively light, the low heat conduction cylinder 3 can bear the pressure, does not need a corrosion-resistant coating, and only needs to be washed with water every month to remove the residual starch.

[0041] The above description of disclosed embodiments enables one skilled in the art to make or use the present application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein can be applied to other embodiments without departing from the spirit or scope of the application. Thus, the present application is not to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
