[0031] To further understand the features, technical means, and specific purposes and functions achieved by the present invention, the present invention will be further described in detail below in conjunction with the drawings and specific implementation modes.

[0032] See Figures 1 to 8 As shown: A low-loss extraction device for feather protein extraction, including a frame 1, an outer extraction chamber 2 rotatably arranged on the frame 1, and an inner extraction chamber 3 rotatably arranged inside it; a through hole 31 communicating with the outer extraction chamber 2 is opened at the bottom of the inner extraction chamber 3, and multiple groups of the through holes 31 are arranged circumferentially along the axis of the outer extraction chamber 2; a sealing element 21 capable of blocking the through hole 31 in a reverse rotation state is further arranged in the outer extraction chamber 2; a separation and concentration module 4 is coaxially and fixedly arranged at the bottom inside the outer extraction chamber 2, and a liquid inlet communicating with the through hole 31 is further opened at the top of the separation and concentration module 4; a heating module 5 is coaxially arranged outside the outer extraction chamber 2, and the heating module 5 is provided with a first heating element 51 and a second heating element 52 respectively used for heating the inner extraction chamber 3 and the separation and concentration module 4; a rotary drive 6 for driving the outer extraction chamber 2 to rotate is further fixedly arranged at the bottom of the frame 1.

[0033] Both the outer extraction chamber 2 and the inner extraction chamber 3 are hollow cylindrical shells with open tops; the outer extraction chamber 2 is movably and fixedly arranged on the frame 1 through a first bearing seat 65 and a second bearing seat 66 coaxially and fixedly arranged at the upper and lower ends of the outer extraction chamber 2 respectively;

[0034] When feather protein needs to be extracted, the staff first pour feather powder into the inner extraction chamber 3 and drive the first heating element 51 to heat the outer extraction chamber 2, so that the feather powder is heated and dissolved with the acidic or alkaline water source arranged in the inner extraction chamber 3 to obtain a clear feather protein solution; since the through holes 31 opened on the outer wall of the inner extraction chamber 3 are blocked by the sealing element 21 at this time; when it is necessary to introduce the clear feather protein solution into the separation and concentration module 4, only need to drive the inner extraction chamber 3 to rotate forward at this time, so as to expose the through holes 31. At this time, the feather protein solution in the inner extraction chamber 3 will flow through the through holes 31 into the separation and concentration module 4, and after being finally separated, concentrated and exported by the separation and concentration module 4; finally, freeze-dry and screen it in turn to obtain the finished feather protein; the rotary driver 6 is composed of a toothed ring 61 coaxially and fixedly arranged outside the outer extraction chamber 2 and a second servo motor 64 fixedly connected to the frame 1 through a third mounting frame 63. The output shaft of the second servo motor 64 is also coaxially and fixedly provided with a driving gear 62 meshing with the toothed ring 61.

[0035] See Figure 8 As shown: A partition 22 is also arranged in the outer extraction chamber 2 and a liquid discharge port is coaxially opened at the bottom thereof. The internal space of the outer extraction chamber 2 is divided into an upper chamber body and a lower chamber body by the partition 22; the inner extraction chamber 3 is fixedly arranged in the upper chamber body, and the separation module is coaxially and fixedly arranged in the lower chamber body; an opening through which the liquid inlet of the separation and concentration module 4 passes is also penetrated through the partition 22; the sealing element 21 is fixedly arranged on the inner wall of the outer extraction chamber 2 and located on the upper surface of the partition 22; a drain pipe 23 is coaxially and fixedly arranged at the liquid discharge port.

[0036] The partition 22 is used to support the inner extraction chamber 3; a plurality of groups of the sealing elements 21 are arranged circumferentially along the axis of the outer extraction chamber 2;

[0037] The diameter of the inner extraction chamber 3 is set smaller than the inner diameter of the outer extraction chamber 2; an annular gap through which the hydrolyzed feather protein hydrolysis solution passes is formed between the inner extraction chamber 3 and the outer extraction chamber 2; the sealing element 21 is fixedly arranged in the annular gap and has the same thickness as the annular gap, so as to block the through holes 31 in the forward rotation state and avoid the leakage of the hydrolysis solution in the hydrolysis state; a locking valve 24 is also coaxially arranged outside the drain pipe 23; the sealing element 21 is composed of a fixed block and a rubber sheet arranged on the surface of the fixed block.

[0038] See Figure 8 As shown: A blocking plate 32 for limiting the forward rotation stroke and reverse rotation stroke of the inner extraction chamber 3 is also vertically arranged on the outer wall of the inner extraction chamber 3, and the blocking plate 32 is arranged close to the through holes 31.

[0039] A plurality of blocking plates 32 are circumferentially arranged along the axis of the inner extraction bin 3, and the distance between every two adjacent blocking plates 32 is greater than the total distance between the through holes 31 and the sealing elements 21; since the blocking plates 32 are arranged close to the through holes 31, when the outer extraction bin 2 is driven to rotate reversely, the sealing elements 21 fixedly arranged on the inner wall of the outer extraction bin 2 will contact the blocking plates 32, and since the blocking plates 32 are arranged close to the through holes 31, the group of sealing elements 21 in contact with the blocking plates 32 will cover outside the through holes 31 at this time, so as to present the effect of sealing the through holes 31 in the reverse rotation state. Similarly, when it is necessary to expose the through holes 31, the outer extraction bin 2 is driven to rotate forward, so that the sealing elements 21 contact another blocking plate 32 arranged opposite to itself to achieve the effect of exposing the through holes 31.

[0040] See Figure 3 and Figure 8 As shown: A cleaning disc 33 capable of cleaning the inner wall of the inner extraction bin 3 is further provided in the inner extraction bin 3; the cleaning disc 33 is driven by a screw rod 37 screwed in the middle thereof.

[0041] The cleaning disc 33 is composed of a disc body and a sealing ring 34 embedded at the edge of the disc body; when it is necessary to scrape the liquid on the inner wall of the inner extraction bin 3 to retain the feather protein to the greatest extent, first, the first servo motor 36 fixedly connected to the frame 1 through the first mounting frame 35 is driven to act, and the output shaft of the first servo motor 36 rotates to drive the screw rod 37 to rotate, so as to drive the cleaning disc 33 to axially slide along the axis of the inner extraction bin 3; the hydrolyzed liquid on the inner wall of the inner extraction bin 3 is scraped towards the bottom of the inner extraction bin 3 by the sealing ring 34 embedded at the edge of the cleaning disc 33 in the sliding state; thus, the effect of cleaning the inner extraction bin 3 is achieved.

[0042] See Figure 7 and Figure 8 As shown: An installation groove 371 is further opened on the side wall of the screw rod 37, and a stirring rod 372 hinged to a hinged part 373 arranged on the side wall of the installation groove 371; a torsion spring is further provided at the hinge of the stirring rod 372 and the hinge seat.

[0043] A magnet 374 for adsorbing the stirring rod 372 is further embedded in the installation groove 371; thus, it is ensured that the stirring rod 372 can be continuously folded in the installation groove 371 during use;

[0044] In order to further improve the hydrolysis effect of feather meal in the inner extraction chamber 3, during the hydrolysis of feather meal, the screw 37 can be driven to rotate at a high speed for a short time. By using the centrifugal force in the state of high-speed rotation, the stirring rod 372 is separated from the magnet 374. At this time, the stirring rod 372 will be twisted to a state perpendicular to the screw 37 under the action of the torsion spring, so as to achieve the effect of continuously stirring the feather meal in the hydrolysis state, thereby improving the hydrolysis efficiency; multiple groups of the stirring rods 372 are alternately arranged along the axis of the screw 37.

[0045] See Figure 4 As shown in the figure: The separation and concentration module 4 includes a separation chamber 41 and a concentration chamber 42 coaxially arranged below the separation chamber 41; the separation chamber 41 is coaxially and fixedly arranged on the lower surface of the partition plate 22, and multiple groups of separation holes for discharging the separation liquid are also formed through the bottom side wall of the separation chamber 41.

[0046] The separation chamber 41 is a hollow funnel-shaped chamber body, and a drainage pipe 411 passing through the partition plate 22 and arranged towards the upper chamber body is opened at the top thereof, and a liquid inlet is opened at the top of the drainage pipe 411;

[0047] When the feather meal is hydrolyzed in the inner extraction chamber 3, by driving the rotary driver 6 to act, the outer extraction chamber 2 is driven to rotate forward, thereby exposing the through hole 31. At this time, the hydrolysis liquid sequentially passes through the through hole 31, the liquid inlet and the drainage pipe 411 and is introduced into the separation chamber 41. After a certain time, when the hydrolysis liquid is completely introduced into the separation chamber 41 through the through hole 31, at this time, the outer extraction chamber 2 is driven to rotate forward at a high speed, so as to cooperate with the separation chamber 41 to remove macromolecular substances and impurities in the hydrolysis liquid, and obtain a clear feather protein liquid, thereby achieving the effect of centrifugal filtration; and the feather protein liquid filtered by the separation chamber 41 will all gather in the concentration chamber 42; finally, drive the second heating element 52 to act to concentrate and heat the feather protein liquid in the concentration chamber 42. After the feather protein liquid is concentrated, open the lock valve 24 to discharge the feather protein liquid from the drain pipe 23.

[0048] See Figure 4 As shown in the figure: The heating module 5 further includes an electromagnetic coil 53, which is fixedly connected to the frame 1 through a second mounting bracket 54, and the electromagnetic coil 53 is coaxially arranged outside the outer extraction chamber 2.

[0049] The first heating element 51 and the second heating element 52 are both heated by the electromagnetic coil 53 coaxially arranged outside the outer extraction chamber 2, so as to achieve the effect of heating the inner extraction chamber 3 and the concentration chamber 42 respectively.

[0050] See Figure 4 As shown in the figure: The first heating element 51 and the second heating element 52 are both made of magnetic materials.

[0051] The magnetic material is preferably a material such as iron, nickel, cobalt, etc. that has good magnetic permeability and magnetization performance. This material is respectively attached and wrapped around the inner extraction bin 3 and the concentration bin 42, so as to achieve the effect of heating the inner extraction bin 3 and the concentration bin 42 respectively when heating it through the electromagnetic coil 53.

[0052] The present invention can complete multiple processes at one time and has functions of automatic transportation and transportation cleaning and scraping, with high feather protein extraction efficiency and small loss.

[0053] The above embodiments only represent one or several implementation manners of the present invention, and the description is relatively specific and detailed, but it cannot be understood as a limitation to the scope of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
