Description

Technical Field

[0001] The invention relates to the technical field of pea protein production, and in particular to a powder drying device for pea protein production. Background Art

[0002] Peas are rich in various nutrients needed by the human body, especially high-quality protein. Moreover, legumes do not contain cholesterol, which is better than animal protein. Pea protein powder is a protein extracted from peas using advanced technology. Pea protein contains all the essential amino acids for the human body and is a complete protein.

[0003] In the prior art, for example, the patent application with publication number CN114838569A proposes a powder drying device for pea protein production, including a fixed table, a cylindrical barrel is arranged at the bottom of the fixed table, a blower is installed on the top of the fixed table, a connecting pipe is fixed on the top of the cylindrical barrel, and the connecting pipe is connected to the inside of the cylindrical barrel, and the air inlet of the blower is installed with an air inlet pipe, and the air inlet pipe passes through the fixed table and is fixed to the connecting pipe. In this invention, the pea protein powder is blown up by the hot air blown by the fan while drying the pea protein powder. The blown pea protein powder will be sucked into the inside of the air inlet pipe by the blower, and then in the process of being transported from the air outlet pipe to the inside of the trapezoidal collection box, the pea protein powder is driven by the wind to flow, rather than flowing in a mass, which is conducive to the drying of the pea protein powder.

[0004] However, the above technical solution still has limitations in actual use. When the pea protein powder enters the barrel for hot air drying, a conical grinding plate is used to grind the heavier agglomerated powder in the input powder. If the amount of agglomerated powder is large, the grinding plate will be blocked, resulting in a decrease in the efficiency of blowing away the powder, and the grinding efficiency of the grinding plate for a large amount of agglomerated powder is not ideal; in addition, the barrel is always connected to the inside of the auger tube for conveying powder, which will cause the wind in the barrel to enter from the output end of the auger tube and then flow out from the input end, thereby affecting the stability of the powder input.

[0038] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0039] The components of the embodiments of the present invention generally described and shown in the drawings herein may be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention.

[0040] Combine the following Figures 1 to 6 As shown, the embodiment of the present invention provides a powder drying device for pea protein production, comprising a body 1 and a collecting box 9, wherein a longitudinally distributed main cavity 11 is provided in the body 1, a transversely distributed feed cavity 12 and a horizontal sliding cavity 13 are provided on the inner wall of the main cavity 11, an airway 14 is provided at one end of the horizontal sliding cavity 13, and an input end of the collecting box 9 is connected to the top of the main cavity 11 through a pipeline;

[0041] A segmented feeding assembly 2 and an auger pipe 3 for connecting to a feeding chamber 12 are provided on one side of the machine body 1. The output end of the auger pipe 3 is connected to the segmented feeding assembly 2. A jet slider 4 for ejecting heated air is slidably connected inside the transverse sliding chamber 13. A cylinder 5 for controlling the transverse sliding of the jet slider 4 and a first air pump 8 for pumping air into the jet slider 4 are provided on the other side of the machine body 1. A motor 6 is provided at the bottom end of the machine body 1. The output end of the motor 6 extends to the inside of the main chamber 11 and is connected to a stirring blade 7.

[0042] When the jet slider 4 is located at the far right end, the outer side of the jet slider 4 matches the inner wall of the main cavity 11 to divide the main cavity 11 into upper and lower spaces. When the jet slider 4 is located at the far left end, the jet slider 4 is connected to the bottom of the main cavity 11 through the airway 14.

[0043] The present invention divides the main cavity 11 into two parts, an upper part and an lower part. When the jet slider 4 is extended, the powder dispersed in the upper space can be directly blown away. By controlling the periodic sliding of the jet slider 4, the main cavity 11 is periodically divided or connected. When the jet slider 4 retracts, the agglomerated powder in the upper space will fall into the lower space and be crushed, and the retracted jet slider 4 can blow away the crushed powder accumulated in the lower space of the main cavity 11, thereby achieving efficient dispersion and drying of the agglomerated powder.

[0044] The present invention improves the powder feeding method at the feeding end of the main cavity 11, so that the powder continuously conveyed by the auger tube 3 can enter the main cavity 11 in sections through the segmented feeding assembly 2, so that the main cavity 11 can only be connected to one or two sections of the material. Therefore, the method of using airflow to blow away the powder in the main cavity 11 will not cause the powder in the auger tube 3 to flow back, thereby ensuring the stable transportation of the powder material.

[0045] Among them, the height of the horizontal sliding cavity 13 is lower than the height of the feed cavity 12, and the horizontal sliding cavity 13 includes a first sliding cavity 131 and a second sliding cavity 132 that are connected end to end. The first sliding cavity 131 is connected to the main cavity 11, and the second sliding cavity 132 is connected to the airway 14. The diameter of the second sliding cavity 132 is larger than the diameter of the first sliding cavity 131.

[0046] The interior of the jet slider 4 is a hollow structure, and an air pipe joint 41, a wire joint 42 and an air jet hole 43 are provided at the top of the jet slider 4. The output end of the first air pump 8 extends into the second slide cavity 132 through a hose and is connected to the air pipe joint 41. The external power supply device extends into the second slide cavity 132 through a wire and is electrically connected to the wire joint 42. A first filter 44 is provided on the inner side of the air jet hole 43. A heating plate 45 electrically connected to the wire joint 42 is installed inside the jet slider 4.

[0047] The air pipe connector 41 and the wire connector 42 are always located in the second slide cavity 132. When the jet slider 4 is at the rightmost end, the jet hole 43 is located in the main cavity 11 and coincides with the central axis of the main cavity 11. When the jet slider 4 is at the leftmost end, the jet slider 4 retracts into the first slide cavity 131, and the jet hole 43 on the jet slider 4 is connected to the second slide cavity 132.

[0048] The input port of the air channel 14 is opened on the inner wall of the second sliding cavity 132 , and the output port at the other end of the air channel 14 is opened on the bottom surface of the main cavity 11 .

[0049] Specifically, the jet slider 4 controlled by the cylinder 5 is extended and retracted periodically. When the jet slider 4 is in the extended state, a part of the jet slider 4 extends out of the first slide cavity 131. At this time, the jet slider 4 is partially in full contact with the inner wall of the main cavity 11, so that the space inside the main cavity 11 is divided into two parts, the upper and lower parts. Since the feeding cavity 12 for feeding is located above the jet slider 4, after feeding from the feeding cavity 12, the powder will naturally fall. The jet slider 4 pumped by the first air pump 8 is always in the jetting state. The first air pump 8 pumps air to the jet slider 4 through the hose and the air pipe joint 41. and heated by the electric heating plate 45, and then ejected from the air jet hole 43 and the first filter screen 44. Since the air jet hole 43 is located in the upper space of the main cavity 11 when the air jet slider 4 separates the main cavity 11, the ejected air will carry powder and be sent to the collecting box 9 through the pipeline (how the collecting box 9 collects the powder carried by the flowing air is a conventional technical means known to those skilled in the art, such as a filter screen, etc., which will not be elaborated here). If there is agglomerated powder in the input powder, it is difficult for the hot air ejected from the air jet slider 4 to blow away the agglomerated powder, so the agglomerated powder will fall on the air jet slider 4.

[0050] When the output end of the cylinder 5 retracts, it will also retract laterally together with the jet slider 4. The portion of the jet slider 4 that was originally used to separate the main cavity 11 will retract into the first cavity 131. At this time, the agglomerated powder that originally fell on the jet slider 4 cannot enter the first cavity 131, and will naturally fall into the lower space of the main cavity 11. By starting the motor 6, the stirring blade 7 on the output end of the motor 6 can start to rotate and break up the agglomerated powder.

[0051] After the jet slider 4 retracts, the jet hole 43 on the jet slider 4 for jetting no longer jets directly into the main cavity 11. As the jet slider 4 retracts until the jet hole 43 is connected to the second slide cavity 132, the gas ejected from the jet hole 43 flows into the airway 14 in the second slide cavity 132, and then is ejected from the bottom of the main cavity 11, so that the powder crushed by the stirring blade 7 is blown into the collecting box 9.

[0052] A plurality of ribs 111 are provided on the inner wall of the main cavity 11, and the plurality of ribs 111 are evenly distributed around the inner circumference of the main cavity 11, and the plurality of ribs 111 are always located below the jet slider 4;

[0053] A second filter screen 112 for the output end of the motor 6 to pass through is provided at the bottom of the main cavity 11 , and the second filter screen 112 is located between the stirring blade 7 and the output port of the air passage 14 .

[0054] Specifically, after the jet slider 4 retracts and causes the agglomerated powder to fall, it is necessary to control the jet slider 4 to extend again to the upper and lower spaces separating the main cavity 11. At this time, the jet slider 4 can still blow away the powder input from the feed cavity 12. At the same time, the space below the main cavity 11 is a relatively closed space, and the motor 6 can be controlled together with the stirring blade 7 to rotate and break up the agglomerated powder.

[0055] Therefore, the space above the main cavity 11 can be used to blow away the dispersed powder, and the rotating stirring blade 7 in the space below the main cavity 11 cooperates with the closed space to break the agglomerated powder separately, which will not reduce the efficiency of blowing away the dispersed powder in the upper space due to breaking the agglomerated powder.

[0056] Furthermore, when the stirring blade 7 rotates to break up the agglomerated powder, if the inner wall of the main cavity 11 is a smooth tubular space, the agglomerated powder will move along the inner circumferential surface of the main cavity 11 after being subjected to force, making it difficult to ensure the breaking effect of the agglomerated powder. Therefore, by setting up a plurality of ribs 111, the agglomerated powder collides with the ribs 111 when moving along the inner wall of the main cavity 11, thereby moving irregularly, so that the stirring blade 7 can fully break up the agglomerated material. The setting of the second filter 112 can prevent powder accumulation from blocking the output port of the air duct 14.

[0057] Among them, the segmented feeding assembly 2 includes a distribution plate 21 fixedly connected to the body 1, the output end of the auger pipe 3 is connected to the interior of the distribution plate 21, the interior of the distribution plate 21 is rotatably connected with a turntable 22, and a plurality of conical material storage troughs 23 are provided on the turntable 22. An air collecting box 24 is provided on the outer side of the distribution plate 21, and a second air pump 25 is installed on the air collecting box 24. A motor 26 for driving the turntable 22 to rotate is installed on the outer side of the distribution plate 21.

[0058] A feed pipe 211 connected to the feed chamber 12 is provided on the side of the material distribution plate 21 close to the body 1, and a third filter screen 212 facing the feed pipe 211 is provided on the side of the material distribution plate 21 away from the body 1. The interior of the material distribution plate 21 is connected to the interior of the air collecting box 24 through the third filter screen 212.

[0059] A plurality of conical material storage grooves 23 are evenly distributed around the center of the turntable 22, each conical material storage groove 23 passes through the turntable 22 horizontally, and each conical material storage groove 23 has a feeding groove 231 extending to the outer circumference of the turntable 22 on its inner wall, and the diameter of the feeding groove 231 is larger than the auger tube 3;

[0060] The width of the feeding channel 231 is greater than the diameter of the output end of the auger tube 3 .

[0061] The diameter of the conical material storage trough 23 at one end close to the machine body 1 is smaller than the diameter of the other end thereof, and the conical material storage trough 23 can be connected to the material delivery pipe 211 and the third filter screen 212 at the same time.

[0062] Specifically, the powder to be dried is continuously input into the segmented feeding assembly 2 through the auger tube 3, and is input into the machine body 1 after being segmented by the segmented feeding assembly 2. The segmented feeding assembly 2 receives the continuously input powder in the following manner: the turntable 22 is continuously rotated by the motor 26, and the multiple conical storage grooves 23 provided on the turntable 22 will successively face the output end position of the auger tube 3. When any conical storage groove 23 faces the output end position of the auger tube 3, the powder output by the auger tube 3 will enter the conical storage groove 23 through the feeding slot 231. As the turntable 22 rotates to the point where the conical storage groove 23 is away from the output end of the auger tube 3, a closed space is formed between the conical storage groove 23 and the inner wall of the distribution plate 21. During the process, as the turntable 22 rotates until one end of the conical material storage trough 23 faces the delivery pipe 211 and the other end faces the third filter screen 212, the air ejected by the second air pump 25 will pass through the third filter screen 212 from the air collecting box 24 to blow the powder in the conical material storage trough 23 into the delivery pipe 211, and then pass through the feed chamber 12 and enter the main chamber 11. As the turntable 22 continues to rotate until the conical material storage trough 23 is away from the delivery pipe 211 and the third filter screen 212, most of the powder in the conical material storage trough 23 is blown out, thereby realizing the segmented input of powder, and this method will not cause the gas ejected from the main chamber 11 and the gas ejected from the air collecting box 24 to affect the powder transported in the auger pipe 3.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
