Description

Technical Field

[0001] This utility model relates to the field of food processing technology, and more specifically to a pastry powder spreading device with a recycling device. Background Technology

[0002] During the production and processing of pastries, it is generally unavoidable to transport semi-finished or shaped pastries to the next step or packaging on a conveyor device. In order to prevent pastries from sticking together or sticking to the conveyor device, flour needs to be sprinkled on the surface of the pastries.

[0003] Existing flour-spreading equipment often causes flour to fly into the air during the spreading process, even spreading throughout the entire production workshop. When the density of flour in the air is high, it can easily harm people's respiratory system. Furthermore, flour is prone to explosion when exposed to open flames, posing a threat to lives. It can also easily accumulate on conveyor belts or other equipment, causing environmental pollution. The easily dispersed nature of flour also increases flour consumption during the spreading process, with only a portion actually being utilized, indirectly increasing the production cost of pastries. Therefore, it is necessary to collect the dispersed flour. Utility Model Content

[0004] The purpose of this invention is to provide a flour-sprinkling device for pastry making with a recycling unit, which can recycle and reuse uncontaminated flour.

[0005] To achieve the above objectives, this utility model provides a flour-sprinkling device for pastry making with a recycling unit, comprising:

[0008] A conveyor device, passing through the lower part of the flour-sprinkling space, includes a conveyor belt. The pastries are placed on the conveyor belt and pass under the flour-sprinkling device, which sprinkles flour onto the pastries.

[0009] The conveyor belt passes through the shield of the powder-spreading space. Along the conveying direction of the dough, the shield through which the conveyor belt passes is defined to form an inlet shield and an outlet shield. Powder-blocking covers that cover the conveyor belt are connected to the inlet shield and the outlet shield respectively. The inlet and outlet channels are defined between the two powder-blocking covers and the conveyor belt. The dough passes through the inlet channel, the powder-spreading space and the outlet channel in sequence on the conveyor belt.

[0010] The recycling device comprises a recycling bin, a filter, a negative pressure generator, and a recycling pipeline set. The recycling bin is located above the flour scattering device and is provided with a valve baffle at the lower end. The valve baffle is used to control the separation and communication between the recycling bin and the flour bin. The recycling bin is further provided with an exhaust port above the valve baffle, which is in communication with the outside and through which flour cannot pass. The upper end of the recycling bin is sealed with a top cover, and the negative pressure generator is arranged on the top cover. The negative pressure generator and the recycling bin are separated by the filter through which flour cannot pass.

[0011] The recycling pipeline set comprises a first recycling pipeline and a second recycling pipeline. The two ends of the first recycling pipeline are connected to the feeding channel and the recycling bin, respectively. The two ends of the second recycling pipeline are connected to the discharging channel and the recycling bin, respectively.

[0012] The negative pressure generator is used to maintain the negative pressure in the recycling bin and the recycling pipeline set, so as to suck the flour into the recycling bin.

[0013] Further, the recycling device further comprises a flour receiving tank located below the conveying belt in the part where the flour scattering space is located, which is used to collect the flour that does not fall onto the conveying belt. The recycling pipeline set further comprises a third recycling pipeline, one end of which is connected to the flour receiving tank, and the other end is connected to the recycling bin.

[0014] Further, the recycling device further comprises a blowing member arranged on the top cover. The blowing member and the recycling bin are separated by the filter through which flour cannot pass. The blowing member is used to blow the flour adhered to the filter.

[0015] Further, the top cover has an upper cover body and a lower cover body. The upper cover body and the lower cover body have a top cover air chamber therebetween. The negative pressure generator and the blowing member are installed on the upper cover body. The upper cover body is provided with a negative pressure hole and a blowing hole, which are used to communicate the top cover air chamber with the negative pressure generator and the blowing member, respectively.

[0016] Further, the filter comprises at least one filter cylinder arranged on the lower surface of the lower cover body. The upper end of each filter cylinder is in communication with the top cover air chamber, and the lower end is located in the recycling bin. The blowing member is connected to an air tank, which is arranged on the top cover.

[0017] Further, one end of the first recycling pipeline, the second recycling pipeline, and the third recycling pipeline is connected to the recycling bin after being communicated with each other. The first recycling pipeline, the second recycling pipeline, and the third recycling pipeline are respectively provided with valves for controlling the communication relationship with the recycling bin.

[0018] Further, the recycling device further comprises two recycling channels and a recycling box located below the flour receiving tank. One end of each recycling channel is arranged below each end of the conveying belt, and the other end is located above the recycling box. The flour falling from both ends of the conveying belt is collected into the recycling box through the recycling channels.

[0019] Further, the exhaust port is a cylindrical structure, which is arranged on the outer wall of the recycling bin, and the outer end of the exhaust port is wrapped with a filter material through which the flour cannot pass.

[0020] Further, the bottom surface of the flour bin is provided with a flour outlet net, and the top surface of the flour bin is provided with a flour bin cover which can be manually opened; the flour scattering device further comprises a flour sweeping assembly arranged in the flour bin, the flour sweeping assembly comprising a rotatable rotating shaft and a plurality of flour sweeping pieces fixed to the rotating shaft and rotating with the rotating shaft in the flour bin, for scattering and sweeping the flour in the flour bin to the flour outlet net.

[0038] In order to further explain the technical scheme of the utility model, the utility model will be described in detail through specific embodiments below.

[0039] Referring to Figures 1 to 4 , a pastry powder scattering equipment with a recycling device is shown, which comprises a powder scattering space, and the powder scattering space is enclosed by blocking surfaces to form a cavity. In this embodiment, the powder scattering space is enclosed by the blocking surfaces around.

[0040] The powder scattering space mainly comprises a powder scattering device 10, a conveying device 20 and a recycling device, wherein the recycling device is the main point of the utility model, and the specific structures of the three devices are described as follows:

[0041] 1. The powder scattering device 10 (for reference in combination with Figure 6), located at the upper part of the powdering space, comprising a powder bin 1, the bottom surface of the powder bin 1 is provided with a powder outlet net 11, and the top surface of the powder bin 1 is provided with a powder bin cover 12 which can be manually opened; the powdering device 10 further comprises a powder sweeping assembly 13 which is arranged in the powder bin 1 and comprises a rotatable rotating shaft 131 and a plurality of powder sweeping pieces 132, the powder sweeping pieces 132 are fixed on the rotating shaft 131 and rotate in the powder bin 1 with the rotating shaft 131, and are used for scattering the flour in the powder bin 1 and sweeping the flour to the powder outlet net 11; specifically, the rotating shaft 131 can be driven to rotate by a motor, and the powder sweeping pieces 132 are circumferentially arranged on the rotating shaft 131. When the powdering process is started, the powder bin cover 12 can be opened to add flour, the flour falls on the powder sweeping assembly 13, is scattered by the rotating powder sweeping pieces 132 and reaches the powder outlet net 11 at the bottom of the powder bin 1, and then falls on the pastry below the powder bin 1 through the powder outlet net 11. The powder sweeping pieces 132 can make the flour reach the powder outlet net 11 at the bottom of the powder bin 1 without accumulating in a certain corner of the powder bin 1, so as to avoid the flour from being lumped together and promote the flour to pass through the powder outlet net 11. The powder outlet net 11 can make the powdering more uniform and avoid the flour from being lumped together and falling.

[0042] 2. The conveying device 20 (see Figure 5 ), passing through the lower part of the powdering space, comprising a conveying belt 2, the pastry is placed on the conveying belt 2 and passes below the powdering device 10, and the powdering device 10 scatters the flour on the pastry. The conveying belt 2 passes through the powdering space and is provided with a powder blocking cover 21 which covers the conveying belt 2. The conveying belt 2 passes through the opposite two blocking surfaces among the blocking surfaces around the powdering space in a straight line, and along the conveying direction of the pastry, the two blocking surfaces through which the conveying belt passes are defined as an inlet blocking surface 101 and an outlet blocking surface 102, respectively. The powder blocking cover 21 is connected to the inlet blocking surface 101 and the outlet blocking surface 102, respectively. The two powder blocking covers 21 and the conveying belt 2 define an inlet channel a and an outlet channel b, respectively. The pastry on the conveying belt 2 passes through the inlet channel a, the powdering space and the outlet channel b in turn. The inlet blocking surface 101 and the outlet blocking surface 102 are arranged to block the flour from escaping to the air outside the pastry powdering device and to facilitate the recovery of the flour.

[0043] Since the conveying belt 2 of the conveying device 20 passes below the powdering device 10, i.e. below the powder outlet net 11, the flour falling from the powder outlet net 11 cannot generally cover the side circumferential surface of the pastry. Therefore, the powdering device 10 further comprises a powder lifting brush 14 which is rotatably arranged below the powder bin 1 and on both sides of the conveying belt 2. The powder lifting brush 14 is driven to rotate by a motor and lifts the flour falling on the conveying belt 2 or the powder lifting brush 14. The lifted flour can contact the pastry from various directions, so that the side circumferential surface of the pastry can also be contacted and coated with the flour.

[0044] The powder scattering device 10 and the conveying device 20 are basic structures in a general pastry powder scattering equipment, and the above only provides an embodiment of the present application, and other embodiments are not described herein.

[0045] The pastry powder scattering equipment further comprises a recycling device, which has a flour recycling function in addition to the powder scattering function, and can collect uncontaminated flour and recycle it.

[0046] The recycling device comprises a recycling bin 3, a filter, a negative pressure generator 34, a blowing member 35 and a recycling pipeline group.

[0047] The recycling bin 3 is located above the powder scattering device 10 and is provided with a valve baffle 32 at the lower end, the valve baffle 32 is used to control the separation and communication between the recycling bin 3 and the flour bin 1, the recycling bin 3 is further provided with an exhaust port 352 which is in communication with the outside and through which flour cannot pass on the peripheral wall above the valve baffle 32, a top cover 31 is sealed to the upper end of the recycling bin 3, the negative pressure generator 34 and the blowing member 35 are arranged on the top cover 31, and the negative pressure generator 34 and the blowing member 35 are separated from the recycling bin 3 by the filter through which flour cannot pass.

[0048] The negative pressure generator 34 is used to maintain the negative pressure in the recycling bin 3 and the recycling pipeline group to suck in the flour, and the blowing member 35 is used to blow off the flour adhered to the filter.

[0049] In other embodiments, the blowing member 35 can be replaced by manual shaking or other equipment.

[0050] Specifically, referring to Figure 3 The recycling bin 3 can have a split structure (divided into three sections), the lowermost section is in communication with the flour bin 1, the valve baffle 32 is arranged at the bottom end of the middle section, the exhaust port 352 is located on the peripheral wall of the middle section, the three recycling pipelines are in communication with the peripheral wall of the uppermost section, and the top cover 31 is sealed to the upper end of the uppermost section.

[0051] The top cover 31 has an upper cover body 311 and a lower cover body 312, and a top cover 31 air cavity is arranged between the upper cover body 311 and the lower cover body 312. The negative pressure generator 34 and the air blowing member 35 are installed on the upper cover body 311. The upper cover body 311 is provided with a negative pressure hole 3111 and an air blowing hole 3112, which are used for communicating the top cover 31 air cavity with the negative pressure generator 34 and the air blowing member 35, respectively. The air blowing member 35 is connected with an air tank 351, and the air tank 351 is arranged on the top cover 31. The air tank 351 stores gas for the air blowing member 35 to blow air.

[0052] The lower cover body 312 is provided with four filter holes 3121. The filter member includes four filter cylinders 33 arranged on the lower surface of the lower cover body 312. The upper end of each filter cylinder 33 is communicated with the top cover 31 air cavity through the filter hole 3121, and the lower end of the filter cylinder 33 is located in the recovery bin 3. The filter cylinder 33 itself has a certain strength, and is not easy to be deformed and damaged due to air pressure when the recovery bin 3 maintains negative pressure. Due to the arrangement of the filter cylinder 33, when the negative pressure generator 34 works, the flour in the recovery bin 3 is isolated on the lower side of the lower cover body 312 and cannot pass through the filter cylinder 33 to enter the top cover 31 air cavity, so it cannot enter the negative pressure generator 34, thereby avoiding flour from blocking the negative pressure generator 34.

[0053] The exhaust port 352 is a cylindrical structure protruding from the outer wall of the recovery bin 3. The outer end of the exhaust port 352 is wrapped with a filter material (not shown in the figure) through which flour cannot pass. The filter material can be a soft sheet similar to cloth, which is tightly wrapped around the exhaust port 352. When the air blowing member 35 works to blow air, the filter material can be deformed and inflated. The air blown by the air blowing member 35 is sprayed out of the recovery bin 3 through the filter material.

[0054] The filter material of the filter cylinder 33 and the filter material wrapped around the outer end of the exhaust port 352 are both filter materials with dense mesh and through which flour cannot pass, and are only used for air to pass through.

[0055] Specifically referring to Figure 2 The flour receiving groove 39 is located below the conveying belt 2 at the part where the flour scattering space is located, and is used to hold the flour that does not fall onto the conveying belt 2 (there is a conveying belt gap 22 between the two sides of the conveying belt 2 and the flour brushing brush 14, and part of the flour may fall from the conveying belt gap 22 into the flour receiving groove 39). One end of the first recovery pipeline 36, the second recovery pipeline 37 and the third recovery pipeline 38 is connected to the recovery bin 3 after being communicated with each other, and the other end of the first recovery pipeline 36, the second recovery pipeline 37 and the third recovery pipeline 38 is connected to the material inlet channel a, the material outlet channel b and the flour receiving groove 39, respectively.

[0056] Preferably, valves S for controlling the communication relationship between the first recovery pipeline 36, the second recovery pipeline 37, the third recovery pipeline 38 and the recovery bin 3 can also be arranged on the first recovery pipeline 36, the second recovery pipeline 37 and the third recovery pipeline 38, respectively, to control whether the three recovery pipelines work.

[0057] When the powder scattering device is working, the recovery device works synchronously, the negative pressure generator 34 keeps the recovery bin 3, the first recovery pipeline 36, the second recovery pipeline 37 and the third recovery pipeline 38 in a negative pressure state, so that the flour that is intended to be scattered into the air from the inlet channel a and the outlet channel b is sucked into the recovery bin 3 through the first recovery pipeline 36 and the second recovery pipeline 37 respectively, and the flour scattering is prevented from being scattered outward; the flour falling into the flour receiving groove 39 is sucked into the recovery bin 3 through the third recovery pipeline 38, so that the flour that is not fallen on the surface of the pastry and is not contaminated can enter the recovery bin 3; when the flour is sucked to a certain amount, the recovered flour can be poured into the flour bin 1 to be reused by opening the valve baffle 32 at the bottom of the recovery bin 3. Therefore, the flour in the pastry powder scattering device is recovered by the recovery device, which not only can inhibit the flour from being scattered in the air, reduce the hidden danger in the workshop and avoid the harm to the respiratory tract of people, but also can further make the uncontaminated flour be reused, reduce the consumption of flour and reduce the production cost.

[0058] Since the flour particles are fine, the filter piece is arranged between the negative pressure generator 34 and the recovery bin 3 to separate and filter the flour, so that the flour is prevented from being blocked in the negative pressure generator 34, and the blowing piece 35 is further arranged, so that when a certain amount of flour is attached to the filter piece, the blowing piece 35 is switched to work to blow (back blow) the flour on the filter piece into the recovery bin 3, so that the flour is prevented from being blocked to affect the working efficiency of the recovery device, and the exhaust port 352 through which the flour cannot pass is further arranged on the recovery bin 3, so as to balance the air pressure in and out of the recovery bin 3 when the blowing piece 35 works.

[0059] Preferably, the utility model further includes two recovery channels 41 and a recovery box 42 located below the flour receiving groove 39, which is used for recovering the flour that is contaminated (may be contacted with the dough with moisture or is agglomerated and cannot be directly used) and falls on the conveying belt 2, one end of the two recovery channels 41 is arranged below the two ends of the conveying belt 2 respectively, and the other end is located above the recovery box 42, so that the flour falling on the two ends of the conveying belt 2 is collected into the recovery box 42 through the recovery channels, so that the flour that can be directly recycled and the flour that cannot be directly recycled are collected separately, and the recycling rate is improved.

[0060] The above is only one embodiment of the utility model, and is not used to limit the utility model, and any modification, equivalent replacement and improvement made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
