[0047] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0048] Referring to Figures 1-15 ,

[0049] A flour pretreatment device for yeast bread preparation, comprising: a weighing bin 1, a filtering pipeline 2, a receiving bin 3, a weighing member and a metering member.

[0050] The weighing bin 1 is used to weigh a preset mass of flour. The weighing bin 1 is fed by a conveying belt, and the flour is weighed by an electronic scale provided in the conveying belt, so that a preset mass of flour is weighed into the weighing bin 1. The weighing bin 1 is a tank in this embodiment, and the weighing bin 1 has an outlet, and the filtering pipeline 2 communicates with the outlet. The filtering pipeline 2 is used to receive the preset mass of flour weighed by the weighing bin 1, and to convey and filter the flour in the conveying direction. The receiving bin 3 is arranged below the filtering pipeline 2, and is used to receive the filtered flour from the filtering pipeline 2. The receiving bin 3 is a sealed box in this embodiment, and a movable receiving bin is provided in the receiving bin, and the receiving bin is used to receive the filtered flour from the filtering pipeline 2. The weighing member is used to measure the mass of the filtered flour from the filtering pipeline 2 received by the receiving bin 3, and the weighing member is an electronic scale. The metering member is used to obtain the output ratio according to the mass of the filtered flour from the filtering pipeline 2 and the preset mass. The metering member is an element with computer function, and the metering member is electrically connected with the weighing member and the weighing bin 1, so that the metering member can obtain the preset mass and the mass of the filtered flour from the filtering pipeline 2, and then the mass of the filtered flour from the filtering pipeline 2 is divided by the preset mass, so that the output ratio can be obtained. Then, if a certain mass of pretreated flour is needed in the next use, the preset mass can be determined according to the output ratio. Thus, the mass of the required pretreated flour can be accurately obtained.

[0051] Specifically, the receiving bins 3 and the weighing members are provided in plurality, and the number of the receiving bins 3 matches the number of the weighing members; the filter pipeline 2 is formed with a plurality of filter regions, and the plurality of filter regions are used for filtering flour of preset mass; and the plurality of filter regions can filter flour of at least partially different particle sizes; that is, some filter regions filter small particle sizes, and some filter regions filter large particle sizes. The metering member is used for weighing the mass of the flour filtered by the different filter regions, and obtaining the output proportion corresponding to the flour of the plurality of particle sizes. The filter region is a region formed by filter holes. Different degrees of flour filtering are realized mainly by the different sizes of the filter holes, for example, flour pre-treatment to obtain flour meeting the requirements, and then some lumps that are difficult to separate or foreign matters remaining, which can also be discharged and classified into the receiving bins 3 according to the particle sizes.

[0052] Specifically, the conveying direction is inclined to the horizontal plane. The flour can be conveyed along the feeding direction by gravity.

[0053] Specifically, the flour pre-treatment device for yeast bread preparation further comprises a driving member 4, which is used to drive the filter pipeline 2 to rotate around a fixed axis. The rotation of the filter pipeline 2 can make the flour move inside the filter pipeline 2 and collide with the inner wall of the filter pipeline 2, thereby facilitating the dispersion of the lumpy flour by collision, so that more lumpy flour can be dispersed and filtered out for use, thereby improving the output proportion to a certain extent.

[0054] Specifically, the filter pipeline 2 comprises a driving section 21, a filter section 22, a closed section 23 and a bending section 24; the filter section 22 and the closed section 23 are provided in plurality, and the filter section 22 and the closed section 23 are in communication; the bending section 24 is provided in plurality, and the plurality of bending sections 24 are used to communicate a plurality of groups of the filter sections 22 and the closed sections 23; the driving section 21 is fixedly communicated with one group of the filter section 22 and the closed section 23; the axis of the driving section 21 coincides with the fixed axis, and the axes of the filter section 22 and the closed section 23 are away from the fixed axis; and the driving member 4 is used to drive the driving section 21 to rotate around the fixed axis.

[0055] The axis of the filtering section 22 is away from the fixed axis, and the filtering section 22 rotates around the fixed axis, and the filtering section 22 is eccentrically moved, which causes the flour in the filtering section 22 to collide with the inner wall of the filtering section 22 under the action of the eccentric movement of the filtering section 22, and the expansion force is large, so that the caked flour is better impacted on the inner wall of the filtering section 22, and the caked flour is better dispersed, and the centrifugal force generated by the eccentric movement is large, so that the kinetic energy of the flour when passing through the filter hole is large, thereby facilitating the flour to quickly pass through the filter hole, which not only improves the dispersion of the caked flour but also improves the filtering speed.

[0056] Specifically, the axes of the adjacent two groups of filtering sections 22 and closed sections 23 are away from the axis by the same distance, and the distance between the axes of the adjacent two groups of filtering sections 22 and closed sections 23 is twice the distance between the axes of the adjacent two groups of filtering sections 22 and closed sections 23 and the axis. In this way, the two adjacent filtering sections 22 are located on both sides of the fixed axis, so that multiple filtering sections 22 can be arranged and the space occupied by the multiple filtering sections 22 can be saved.

[0057] Specifically, the flour pretreatment device for preparing yeast bread further comprises a blocking piece 5; the blocking piece 5 is used to contact at least the filtering section 22 when the filtering pipeline 2 rotates around the fixed axis.

[0058] Specifically, the blocking piece 5 comprises a fixed rod 51, a baffle 52, a torsional spring 53, and a limiting rod 54; the baffle 52 is rotationally connected with the fixed rod 51, the torsional spring 53 is arranged between the fixed rod 51 and the baffle 52, and is used to enable the baffle 52 to be elastically rotated in the same direction as the rotation direction of the filtering pipeline 2; the limiting rod 54 is used to abut against the baffle 52, and is used to limit the baffle 52 at a position where the extension direction of the baffle 52 passes through the fixed axis; when the filtering pipeline 2 rotates around the fixed axis, the filtering pipeline 2 contacts the baffle 52. The baffle 52 contacts the filtering pipeline 2, so that the filtering pipeline 2 is impacted, thereby causing the filtering pipeline 2 to vibrate when rotating around the fixed axis, which plays a role of vibrating and screening materials, and better enables the flour to quickly pass through the filter hole. The baffle 52 is connected with the fixed rod 51 through a fixed ring.

[0059] The receiving bin 3 is provided with a through opening for the filter pipe 2, and a circular plate 31 is arranged at the through opening and is rotatably connected with the through opening. The through opening is a circular opening, and the center of the through opening coincides with the fixed axis. The filter pipe 2 is fixed with the circular plate 31, so that the circular plate 31 guides the rotation of the filter pipe 2. The end surface of the circular plate 31 is perpendicular to the fixed axis. A fixed rod 51 is fixed with the receiving bin 3, a limiting rod 54 is fixed with the receiving bin 3, a fixed ring is rotatably connected with the fixed rod 51, and a baffle 52 is fixed with the fixed ring.

[0060] Specifically, the baffle 52 comprises a first contact part 521, a second contact part 522, an adhesive part 523 and a protruding part 524. The first contact part 521 is fixed with the second contact part 522. Both the first contact part 521 and the second contact part 522 are C-shaped, and the first contact part 521 and the second contact part 522 are fixed to form an S shape. The adhesive part 523 is used for adhering to the first contact part 521 and the second contact part 522 which are fixed together. The first contact part 521 is fixed with the fixed ring. A plurality of protruding parts 524 are arranged, and the plurality of protruding parts 524 are fixed with the adhesive part 523. The adhesive part 523 is located at one end of the first contact part 521 and the second contact part 522 which can contact the filter pipe 2. Both the first contact part 521 and the second contact part 522 are plate bodies. The adhesive part 523 is fixed with the first contact part 521 and the second contact part 522 by means of gluing. The adhesive part 523 is a flexible material, and is preferably a rubber material. The protruding part 524 is also a rubber material. The protruding part 524 is a rod body structure, and is fixed with the adhesive part 523. A plurality of protrusions are formed on the protruding part 524, and the protrusions are integrally formed with the protruding part 524. The protrusions can be partially inserted into the filter holes on the filter section 22 when the protruding part 524 contacts the filter section 22.

[0061] In use, the filter pipe 2 rotates towards the baffle 52 first, and then the filter pipe 2 contacts the baffle 52. The filter pipe 2 contacts the second contact part 522 first, and then the filter pipe 2 rotates around the fixed axis to force the baffle 52 to rotate, so that the filter pipe 2 contacts the second contact part 522 at least at two positions. Then, different positions of the second contact part 522 contact the filter pipe 2, so that the second contact part 522 can relatively move with the outer wall surface of the filter pipe 2, thereby scraping the outer wall surface of the filter pipe 2 to make part of the flour on the outer wall surface of the filter pipe 2 fall off the filter pipe 2, thereby improving the collection degree of the flour filtered by the filter pipe 2, and improving the output ratio to a certain extent.

[0062] There are some cases, when the C-shaped opening of the first contact part 521 and the second contact part 522 is greater than or equal to the diameter of the filter pipe 2, the second contact part 522 will rotate to the part of the filter pipe 2 located inside the C-shaped opening of the second contact part 522, thereby increasing the contact area of the filter pipe 2 and the second contact part 522, and the first contact part 521 and the second contact part 522 can be in point contact with the filter pipe 2 first, causing the filter pipe 2 to vibrate, and then in surface contact with the filter pipe 2, and the outer wall surface of the filter pipe 2 is in surface contact with the filter pipe 2. When the surface is in contact with the surface, the first contact part 521 and the second contact part 522 C-shaped opening will be closed due to the contact of the filter pipe 2 with the C-shaped opening of the first contact part 521 or the second contact part 522, and the filter pipe 2 will continue to rotate, which may be an arc filter pipe 2 completely embedded in the inside of the C-shaped opening of the first contact part 521 or the second contact part 522, or it may be directly separated from the first contact part 521 or the second contact part 522, which will cause part of the filter area of the filter pipe 2 to be subjected to vacuum suction or external high pressure, so that the filter area can be kept unobstructed at all times, and the filtering effect is improved.

[0063] Specifically, the flour pretreatment device for preparing yeast bread further comprises a connecting pipeline 6 and a support 7. The support 7 is used to install the connecting pipeline 6 and the weighing bin 1. The connecting pipeline 6 is used to fixedly communicate the driving section 21 with the weighing bin 1, and specifically, the connecting pipeline 6 is rotationally connected with the driving section 21. An annular plate 8 and a stirring column 81 are arranged inside the filter pipeline 2. The stirring column 81 is fixed with the annular plate 8. The annular plate 8 is arranged in the driving section 21, and the annular plate 8 is fixed with the driving section 21. The stirring column 81 is partially arranged in the connecting pipeline 6. The connecting pipeline 6 has at least a stirring section which coincides with the extension direction of the driving section 21. The stirring column 81 is arranged in the stirring section. The connecting pipeline 6 is fixed with the weighing bin 1. When the driving section 21 rotates, the driving section 21 drives the annular plate 8 to rotate, and the annular plate 8 drives the plurality of stirring columns 81 to rotate, so that the stirring columns 81 rotate in the connecting pipeline 6, and the stirring columns 81 stir the flour in the connecting pipeline 6. Since the connecting pipeline 6 cannot rotate, this way can prevent the connecting pipeline 6 from being blocked to a certain extent.

[0064] Specifically, a fixed block 9 is arranged at the weighing bin 1, and the fixed block 9 is fixed with the support 7. A through hole is formed in the fixed block 9, and the connecting pipeline 6 and the driving section 21 are inserted into the through hole and are butted together, so that the sealing performance of the driving end after being connected with the connecting pipeline 6 is better. The driving member 4 includes a driving motor 41, a first gear 42 and a second gear 43. The driving motor 41 is installed on the fixed block 9, the first gear 42 is rotationally connected with the fixed block 9, and the second gear 43 is fixed with the driving section 21. The driving motor 41 drives the second gear 43 to rotate through the first gear 42, so as to realize the rotation of the driving section 21 around the fixed axis.

[0065] Workflow:

[0066] Firstly, the flour to be pretreated is placed in the weighing bin 1, and the mass thereof is 20 kg. Then the flour reaches the driving section 21 through the connecting pipeline 6, and then reaches the filtering section 22 and the closed section 23 along the driving section 21. Then the flour is blocked by the bending section 24, so that the flour cannot reach the other filtering section 22 and closed section 23 adjacent thereto. Then the driving member 4 drives the driving section 21 to rotate, so as to make the plurality of filtering sections 22, closed sections 23 and bending sections 24 rotate. Then the flour originally in the filtering section 22 passes through the bending section 24 to reach the other filtering section 22 for filtering, so as to realize the conveying and filtering of the flour at the same time.

[0067] In addition, when the filtering pipeline 2 rotates around the fixed axis, firstly, the filtering pipeline 2 rotates towards the baffle 52, and then the filtering pipeline 2 contacts with the baffle 52. Firstly, the filtering pipeline 2 contacts with the second contact part 522, and then the rotation of the filtering pipeline 2 around the fixed axis forces the baffle 52 to rotate, so that the second contact part 522 exists in the relative motion with the outer wall surface of the filtering pipeline 2. Therefore, the outer wall surface of the filtering pipeline 2 can be scraped, so that part of the flour on the outer wall surface of the filtering pipeline 2 can be separated from the filtering pipeline 2, thereby improving the collection degree of the flour filtered by the filtering pipeline 2, and improving the output ratio to a certain extent.

[0068] The second contact part 522 is also rotated to the position where the filter pipe 2 is located inside the C-shaped opening of the second contact part 522, thereby increasing the contact area between the filter pipe 2 and the second contact part 522. The first contact part 521 and the second contact part 522 can first make point contact with the filter pipe 2, causing the filter pipe 2 to vibrate, and then make surface contact with the filter pipe 2 to scrape the outer wall surface of the filter pipe 2. When the surfaces make contact, the first contact part 521 and the second contact part 522 are closed inside the C-shaped opening due to the contact between the filter pipe 2 and the C-shaped opening of the first contact part 521 or the second contact part 522. As the filter pipe 2 continues to rotate, it may be completely embedded in the C-shaped opening of the first contact part 521 or the second contact part 522 in an arc, or it may directly separate from the first contact part 521 or the second contact part 522. This can cause part of the filter area of the filter pipe 2 to be subjected to vacuum suction or external high pressure, allowing the filter area to remain unblocked at all times and improving the filtering effect.

[0069] Thus, more pre-processed flour can be collected. The plurality of receiving bins 3 are arranged to receive the flour filtered out of the filter areas of the plurality of filter pipes 2.

[0070] The plurality of receiving bins 3 are specifically four, three of which are arranged to receive pre-processed flour that can be used, and the other is arranged to receive pre-processed flour that cannot be used. The flour that can be used is flour that is not clumped, and the flour that cannot be used is a mixture of flour that is still clumped after being transported and vibrated and part of foreign matter.

[0071] Therefore, the quality of the flour filtered out of the filter pipe 2 is the quality of the flour in the three receiving bins 3 that receive pre-processed flour that can be used. The other receiving bin 3 can optionally measure the weight or not measure the weight.

[0072] If the quality of the flour filtered out of the filter pipe 2 is 19.76 kg when the pre-set quality is 20 kg, the yield ratio is 98.8%. If 100 kg of pre-processed flour is needed, 101.215 kg of flour can be placed in the weighing bin 1. Thus, the quality of the pre-processed flour needed can be accurately obtained at one time.

[0073] If the other receiving bin 3 also measures the weight, when the preset mass is 20 kg, the mass of the flour filtered by the filter pipe 2 is 19.76 kg, and the weight of the other receiving bin 3 is 0.21 kg. Thus, it can be known that 0.03 kg of flour will be adhered to the filter pipe 2 or the connecting pipe 6 or the weighing bin 1 when 20 kg of flour is not pretreated. After pretreating a certain mass of flour, the mass of the adhered flour can be inferred, and the filter pipe 2, the connecting pipe 6 and the weighing bin 1 can be cleaned according to the mass of the adhered flour at any time.

[0074] The above description is merely some preferred embodiments of the present disclosure and a description of the principles of the technology used. Those skilled in the art should understand that the scope of the application involved in the embodiments of the present disclosure is not limited to the technical solutions formed by the specific combinations of the above technical features, and should also cover other technical solutions formed by any combinations of the above technical features or equivalent features without departing from the above inventive concept.
