[0043] Please refer to Figure 1 and Figure 2 , Figure 1 The structure schematic diagram of the wine starter production equipment 100 provided by the present embodiment is shown in the figure. Figure 2 The structure schematic diagram of the wine starter production equipment 100 provided by the present embodiment is shown in the figure.

[0044] The present application provides a kind of wine starter production equipment 100, the wine starter production equipment 100 includes accommodating unit 110, crushing unit 120, stirring unit 130, elevator 140 and first screw conveyor 150;Elevator 140 is used to drive accommodating unit 110 switches between feeding position and discharging position;Crushing unit 120 is used to receive the raw material released by accommodating unit 110 in discharging position, and the raw material powder after crushing is conveyed to stirring unit 130 by first screw conveyor 150.

[0045] Specifically, accommodating unit 110 includes raw material bin 111, raw material bin 111 is drivingly connected with elevator 140, raw material bin 111 can be switched between feeding position and discharging position under the drive of elevator 140.When raw material bin 111 is moved from feeding position to discharging position, the raw material outlet of raw material bin 111 is opened, so that raw material can be moved to crushing unit 120 by raw material outlet.

[0046] First screw conveyor 150 is provided with conveying inlet a1( Figure 7 As shown by mark a1 in the figure), so that the raw material powder after crushing of crushing unit 120 can enter first screw conveyor 150 from conveying inlet a1;First screw conveyor 150 is provided with conveying outlet a2( Figure 7 As shown by mark a2 in the figure), so that the raw material powder in first screw conveyor 150 can enter stirring unit 130 from conveying outlet a2. Thus, the raw material powder is conveyed from crushing unit 120 to stirring unit 130 by first screw conveyor 150. After stirring to form wine starter, it can be stepped to obtain starter block with regular shape and uniform size, and then wine is brewed.

[0047] It should be noted that the shape of the raw material bin 111 in this embodiment is funnel-shaped, and the elevator 140 is a bucket elevator. In other embodiments, the raw material bin 111 can also adopt other shapes and structures capable of containing raw materials; the elevator 140 can also adopt other structures capable of driving the raw material bin 111 to move up and down.

[0048] After obtaining the koji block, the koji block can be used for subsequent wine brewing steps. Before that, the koji block needs to be crushed into powder and packaged in bags for subsequent use. In the crushing and packaging process, the crushing unit 120 and the elevator 140 in this embodiment are also needed.

[0049] It can be understood that the working principle of the koji making equipment 100 is as follows:

[0050] The koji making equipment 100 first fills the raw material bin 111 with raw materials through the raw material inlet of the raw material bin 111, and then moves the raw material loading position of the raw material bin 111 to the raw material unloading position through the elevator 140. Then, the raw material outlet is opened, and the raw materials enter the crushing unit 120 from the raw material bin 111, so as to crush the raw materials into powder.

[0051] After crushing, the crushing unit 120 transports the raw material powder to the stirring unit 130 through the first screw conveyor 150, and the stirring unit 130 stirs and mixes the raw material powder and water together to form koji. Finally, a plurality of regular-shaped and uniformly-sized koji blocks are obtained by treading.

[0052] Please refer to Figure 2 In this embodiment, the crushing unit 120 is located at layer A, and the stirring unit 130 is located at layers B and C; the elevator 140 penetrates layers A and B to transport the raw material bin 111 from layer A to layer B, or from layer B to layer A. It can be understood that the raw material loading position of the raw material bin 111 is layer B, and the raw material unloading position is layer A.

[0053] When the raw material bin 111 is filled in layer B, the elevator 140 will lift the raw material bin 111 from layer B to layer A; when the raw material bin 111 is unloaded in layer A, the elevator 140 will lower the raw material bin 111 from layer A to layer B, and the cycle will continue.

[0054] When the raw material bin 111 reaches layer A and is located above the crushing unit 120, the raw material outlet of the raw material bin 111 is opened, so that the raw materials in the raw material bin 111 can enter the crushing unit 120 through the raw material outlet. The crushing unit 120 crushes the raw materials into powder.

[0055] Since the crushing unit 120 is located at the A layer, and the stirring unit 130 is located at the B layer and the C layer, the A layer is the upper floor of the B layer, and the C layer is the lower floor of the B layer; therefore, in the embodiment, the raw material powder needs to be transported from the high floor to the low floor.

[0056] According to the above, the koji making equipment 100 further comprises a second screw conveyor 160; the second screw conveyor 160 is in driving connection with the elevator 140, and is connected with the containing unit 110; the second screw conveyor 160 is used to receive the raw material released by the containing unit 110 in the discharging position, and transport the raw material to the crushing unit 120.

[0057] It can be understood that when the raw material bin 111 is moved from the feeding position to the discharging position, the raw material outlet of the raw material bin 111 is not necessarily directly opposite to the crushing unit 120; therefore, in order to ensure that the raw material in the raw material bin 111 can enter the crushing unit 120, the second screw conveyor 160 is arranged in the embodiment to receive the raw material released by the raw material bin 111 in the discharging position, and transport the raw material to the crushing unit 120.

[0058] When the raw material bin 111 is moved from the feeding position to the discharging position, the raw material outlet and the conveying inlet b1 (indicated by b1 in the figure) of the second screw conveyor 160 are communicated, the raw material outlet is opened, so that the raw material in the raw material bin 111 is released to the second screw conveyor 160, and then the second screw conveyor 160 transports the raw material to the crushing unit 120 through the conveying outlet b2 (indicated by b2 in the figure), thereby improving the utilization rate of the raw material and reducing the production cost. Figure 8 Figure 8 It should be noted that in the embodiment, the second screw conveyor 160 is connected with the raw material bin 111, and is in driving connection with the elevator 140, so that the elevator 140 can drive the second screw conveyor 160 and the raw material bin 111 to move synchronously.

[0059] Moreover, the conveying speed of the second screw conveyor 160 adopted in the embodiment can be adjusted, so as to avoid that the crushing machine 121 in the crushing unit 120 continuously operates at high frequency due to too much raw material, and the temperature of the crushing machine 121 is too high, the wear of the crushing machine 121 is too large, the crushing machine 121 is damaged, and the service life of the crushing machine 121 is ensured.

[0060] In other embodiments, the second screw conveyor 160 is connected with the crushing unit 120, that is, the position of the second screw conveyor 160 is fixed, and the elevator 140 is in driving connection with the raw material bin 111 to directly drive the raw material bin 111.

[0061] In other embodiments, the second screw conveyor 160 is connected with the crushing unit 120, that is, the position of the second screw conveyor 160 is fixed, and the elevator 140 is in driving connection with the raw material bin 111 to directly drive the raw material bin 111.

[0062] ​In the embodiment, the raw material outlet of the raw material bin 111 is always in communication with the conveying inlet b1 of the second screw conveyor 160 due to the connection between the raw material bin 111 and the second screw conveyor 160. In other embodiments, the second screw conveyor 160 is connected to the crushing unit 120, and thus the raw material outlet of the raw material bin 111 is in communication with the conveying inlet b1 of the second screw conveyor 160 only when the raw material bin 111 is in the discharging position.

[0063] Further, referring to Figure 1 and Figure 2 In the embodiment, the crushing unit 120 includes a crusher 121 and a sorter 122, the sorter 122 is arranged at the crushing inlet of the crusher 121, the sorting outlet of the sorter 122 is in communication with the crushing inlet of the crusher 121, and the sorter 122 is used to sort the raw material released by the accommodation unit 110 in the discharging position. The sorted raw material enters the crusher 121 through the communicated sorting outlet and crushing inlet.

[0064] It can be understood that the conveying outlet b1 of the second screw conveyor 160 is in communication with the sorting inlet of the sorter 122, so that the raw material conveyed by the second screw conveyor 160 can first pass through the sorter 122, and then enter the crusher 121 after the impurities mixed in the raw material are sorted out by the sorter 122, thereby avoiding the presence of impurities in the raw material powder obtained by crushing the crusher 121 and improving the quality of the distiller's yeast.

[0065] In the embodiment, the elevator 140 can lift the second screw conveyor 160 to the upper side of the crushing unit 120, so that the raw material is conveyed from the upper floor to the lower floor, i.e. from the top to the bottom. Therefore, the sorter 122 is located above the crusher 121, and the crushing inlet is arranged above the crusher 121 to receive the raw material sorted by the sorter 122.

[0066] According to the above, the stirring unit 130 includes a mixing bin 131, a third screw conveyor 132, and a first stirrer 133. The mixing bin 131 is used to receive the raw material powder crushed by the crushing unit 120, and the third screw conveyor 132 is used to convey the raw material powder mixed uniformly to the first stirrer 133.

[0067] It should be noted that the number of raw material bins 111 in the embodiment is multiple, because the raw materials for making distiller's yeast include multiple materials such as small koji, wheat, barley, peas, and rice bran. In order to ensure the quality of the distiller's yeast, the multiple materials need to be mixed uniformly according to a certain proportion, and then water is added for stirring to make the distiller's yeast.

[0068] Therefore, the stirring unit 130 in the embodiment comprises a mixing bin 131, a third screw conveyor 132 and a first stirrer 133; the raw material powder crushed by the crusher 121 flows out from the crushing discharge port of the crusher 121 and flows into the first screw conveyor 150 through the conveying inlet a1 of the first screw conveyor 150. The conveying discharge port a2 of the first screw conveyor 150 and the mixing inlet of the mixing bin 131 are communicated, so that the raw material powder in the first screw conveyor 150 can enter the mixing bin 131 through the conveying discharge port a2 of the first screw conveyor 150 and the mixing inlet of the mixing bin 131, so that the plurality of raw materials are uniformly mixed together.

[0069] The mixing bin 131 in the embodiment is a funnel structure, that is, the mixing inlet is located above the mixing bin 131, and a mixing discharge port is further arranged below the mixing bin 131, and the mixing discharge port is communicated with the conveying inlet c1 (as shown by sign c1 in FIG. 6) of the third screw conveyor 132; after the plurality of raw material powders are uniformly mixed together, the mixing discharge port is opened, so that the uniformly mixed raw material powder can flow out through the mixing discharge port and enter the third screw conveyor 132 through the conveying inlet c1 of the third screw conveyor 132. The conveying discharge port c2 of the third screw conveyor 132 and the stirring inlet of the first stirrer 133 are communicated, so that the uniformly mixed raw material powder in the third screw conveyor 132 can enter the first stirrer 133 through the conveying discharge port c2 of the third screw conveyor 132 and the stirring inlet of the first stirrer 133; so as to stir the uniformly mixed raw material powder and water together to make the distiller's yeast. Figure 3

[0070] Please refer to Figure 2 In the embodiment, the number of the third screw conveyors 132 and the first stirrers 133 is multiple, each third screw conveyor 132 corresponds to one first stirrer 133 and is arranged on the same floor; and different third screw conveyors 132 are arranged on different floors.

[0071] The mixing bin 131 in the embodiment is located on the B layer, therefore, the uniformly mixed raw material powder in the mixing bin 131 can be directly conveyed to the third screw conveyor 132 located on the B layer. Another third screw conveyor 132 is located on the C layer, in order to ensure that the raw material powder does not fly into the air during the conveying process and avoid causing safety accidents; a conveying pipeline needs to be arranged, and two ends of the conveying pipeline are respectively communicated with the mixing discharge port and the conveying inlet c1 of the third screw conveyor 132 on the C layer, so as to convey the uniformly mixed raw material powder to the third screw conveyor 132.

[0072] ​It should be noted that the end of the conveying inlet c1 of the third screw conveyor 132 is in contact with the ground, however, since the first mixer 133 has a certain height, in order to ensure that the third screw conveyor 132 can convey the uniformly mixed raw material powder to the first mixer 133, the third screw conveyor 132 needs to be placed obliquely, that is, the end of the conveying outlet c2 of the third screw conveyor 132 should be higher than and directly opposite the stirring inlet of the first mixer 133, so that the uniformly mixed raw material powder falls from the conveying outlet c2 of the third screw conveyor 132 into the first mixer 133.

[0073] In order to avoid the uniformly mixed raw material powder flying out during movement, improve the utilization rate of raw materials, and reduce production costs in the embodiment, the third screw conveyor 132 needs to receive as much uniformly mixed raw material powder as possible from the mixed outlet of the mixing bin 131; therefore, in the embodiment, part of the third screw conveyor 132 is arranged transversely, and the other part of the third screw conveyor 132 is arranged obliquely, so that more uniformly mixed raw material powder is conveyed into the first mixer 133 through the cooperation of multiple third screw conveyors 132, avoiding the uniformly mixed raw material powder flying out of the third screw conveyor 132 during conveying, causing waste and existing safety hazards.

[0074] According to the above content, please refer to Figures 1-3 In the embodiment, the number of mixing bins 131 is also multiple, and each conveying inlet c1 and each conveying outlet c2 of the third screw conveyor 132 is provided with a valve 134; the valve 134 corresponding to the conveying inlet c1 is used to open or close the conveying inlet c1; and the valve 134 corresponding to the conveying outlet c2 is used to open or close the conveying outlet c2.

[0075] The staff can control the opening or closing of the conveying inlet c1 and the conveying outlet c2 according to the capacity of the raw material powder in the mixing bin 131 and the stirring speed of the first mixer 133. For example, when the amount of raw material powder in the mixing bin 131 is small and only one first mixer 133 can complete stirring, one conveying outlet c2 is opened to make one first mixer 133 work, avoiding resource waste. When the multiple raw material powders in a certain mixing bin 131 have not been uniformly mixed together, the conveying inlet c1 corresponding to the mixing bin 131 is closed to avoid the uniformly mixed raw material powder entering the first mixer 133, affecting the quality of the starter obtained by stirring.

[0076] It should be noted that since the mixing bin 131 is provided with multiple, the conveying outlet a2 of the first screw conveyor 150 is also provided with multiple, and each conveying outlet a2 is connected to the mixing inlet of one mixing bin 131.

[0077] In order to facilitate the mixing of a plurality of materials in the mixing bin 131, a plurality of raw material bins 111 are provided in the embodiment, each of which contains a material. In the embodiment, the number of crushing units 120 can also be multiple, each of which corresponds to a raw material bin 111 to crush a raw material, so as to adjust the mixing ratio of different raw material powders by adjusting the crushing speed of different crushing units 120. In the embodiment, the number of first screw conveyors 150 can also be multiple, and the mixing ratio of different raw material powders is adjusted by adjusting the movement speed of different first screw conveyors 150.

[0078] Please refer to Figure 4 and Figure 5 , Figure 4 the structural schematic diagram of the koji making equipment 100 provided in other embodiments; Figure 5 the structural schematic diagram of the koji making equipment 100 provided in other embodiments with a dust removal unit 170.

[0079] In other embodiments, the crushing unit 120 further comprises a flow controller 123 arranged at the sorting feed inlet of the sorter 122. It should be noted that the koji making equipment 100 of the embodiment is mainly used to make koji by using small koji, and when it is necessary to make koji by using large koji, the amount of large koji entering the crusher 121 needs to be adjusted, because the volume of large koji is large, and the difference in shape and volume between different large kojis is also large, so that the crushing effect is poor if there is too much large koji in the crusher 121, and the crusher 121 may even be damaged. Therefore, the flow controller 123 is arranged in other embodiments to assist in adjusting the feed speed.

[0080] In other embodiments, the accommodating unit 110 further comprises a mother koji bin 112. Since other embodiments use large koji to make koji, and the volume of large koji is too large, directly crushing the large koji and the mother koji together may result in too little mother koji or uneven mixing, which affects the quality of the koji. Therefore, the mother koji bin 112 is separately arranged, and after the large koji and other raw materials are uniformly mixed, the mother koji is added so that the mother koji can be uniformly mixed with the raw material powder to make koji.

[0081] In other embodiments, the stirring unit 130 further comprises a second stirrer 135, and the third screw conveyor 132 is used to convey the uniformly mixed raw material powder to the second stirrer 135.

[0082] It should be noted that, since the mother starter in other embodiments is not mixed in the raw material bin 111 at the beginning, but is added to the raw material powder in the process of being transported by the third screw conveyor 132, the second mixer 135 in other embodiments needs to mix the uniformly mixed raw material powder, the mother starter, and water together. Therefore, the second mixer 135 needs to be selected for mixing.

[0083] In other embodiments, the stirring unit 130 further comprises a buffer bin 137, the buffer bin 137 is used to receive the uniformly mixed raw material powder transported by the third conveyor before the second mixer 135, and the buffer bin 137 is in the form of a funnel structure, so that the uniformly mixed raw material powder can move at a uniform speed to be uniformly mixed with the mother starter; avoid a large amount of raw material powder from gathering together, causing the raw material powder and the mother starter to be mixed unevenly, affecting the quality of the starter.

[0084] Please refer to Figure 4 In other embodiments, the mixing bin 131 is located on the B layer, and the number of the third screw conveyors 132 and the second mixers 135 is also multiple to improve the efficiency of starter making. Each third screw conveyor 132 corresponds to one second mixer 135. The conveying inlet c1 of the third screw conveyor 132 located on the B layer is directly opposite the mixing outlet of one mixing bin 131, so as to directly receive the uniformly mixed raw material powder falling from the mixing outlet.

[0085] The third screw conveyors 132 located on the C layer and the D layer are in communication with the conveying pipeline, and the uniformly mixed raw material powder is transported to the third screw conveyors 132 on the C layer and the D layer through the conveying pipeline. Other embodiments are provided with a flow divider 136 to divide the uniformly mixed raw material powder equally, so that the amount of uniformly mixed raw material powder transported to the C layer and the D layer is consistent.

[0086] In other embodiments, the number of the mother starter bins 112 and the buffer bins 137 is also multiple, and each buffer bin 137 is arranged on a different floor; and each floor is provided with a mother starter bin 112, and the number of the mother starter bins 112 on each floor is the same.

[0087] Further, please refer to Figures 1-6 The starter making equipment 100 further comprises a dust removal unit 170 and a first air pipe 180; the dust removal unit 170 is in communication with the first air pipe 180, and the dust removal unit 170 is used to absorb and sort dust and raw material powder; the first air pipe 180 is used to transport the raw material powder sorted by the dust removal unit 170 to the mixing bin 131.

[0088] Specifically, the dust removal unit 170 comprises a dust suction hood 171, a pulse dust removal machine 172, a second air pipe 173, a fan 174 and an air compressor 175; the dust suction hood 171 is arranged at the feeding position; two ends of the second air pipe 173 are respectively communicated with the dust suction hood 171 and the pulse dust removal machine 172; the first air pipe 180 is communicated with the pulse dust removal machine 172; the fan 174 and the air compressor 175 are both communicated with the pulse dust removal machine 172; the dust suction hood 171 is used for absorbing dust and raw material powder at the feeding position; the second air pipe 173 is used for conveying the dust and part of the raw material absorbed by the dust suction hood 171 to the pulse dust removal machine 172; the pulse dust removal machine 172 is used for sorting the dust and part of the raw material; the fan 174 is used for absorbing dust in the air and raw material powder flying out from the crushing unit 120 and conveying to the pulse dust removal machine 172; the air compressor 175 is used for conveying air to the pulse dust removal machine 172.

[0089] Please refer to Figure 2 The dust suction hood 171 is arranged at the feeding position to absorb dust in the feeding process; dust is prevented from entering the raw material bin 111. However, part of the raw material with small volume may also be absorbed by the dust suction hood 171, therefore, the dust and part of the raw material absorbed need to be conveyed to the pulse dust removal machine 172 through the second air pipe 173 to separate the dust and part of the raw material, and then the sorted part of the raw material can be conveyed to the mixing bin 131 through the first air pipe 180 to improve the utilization rate of the raw material.

[0090] In the process that the second screw conveyor 160 conveys the raw material to the crushing unit 120, part of the raw material may fly out to float in the air; in order to avoid the dust in the air from causing explosion to improve safety, the fan 174 is arranged to absorb the dust and part of the raw material in the air and convey to the pulse dust removal machine 172, so that the pulse dust removal machine 172 can sort part of the raw material and convey to the mixing bin 131 through the first air pipe 180 to improve the utilization rate of the raw material.

[0091] It should be noted that the dust removal unit 170 in the embodiment further comprises an air compressor 175 to provide air source for the pulse dust removal machine 172 to promote the efficiency of the pulse dust removal machine 172 in separating the dust and part of the raw material.

[0092] Please refer to Figure 2 The raw material bin 111 is arranged at the B layer, therefore, raw material can be poured into the raw material bin 111 located at the B layer from the A layer which is one layer higher than the B layer, so the dust suction hood 171 is arranged at the A layer in the embodiment.

[0093] The fan 174 is used for absorbing part of the raw material flying out from the crushing unit 120, and according to the principle of air flow, the fan 174 is arranged at the B layer. Figure 2The crushing unit 120 in the embodiment is located at the A layer, and therefore the dust suction cover 171 and the fan 174 of the dust removal unit 170 need to be arranged at the A layer. In order to improve the conveying efficiency, the pulse dust removal machine 172 and the air compressor 175 are arranged at the A layer, that is, the dust removal unit 170 is arranged at the A layer; and a part of the first air pipe 180 is located at the A layer, and the other part is located at the B layer, so as to convey the part of the raw materials in the pulse dust removal machine 172 located at the A layer to the mixing bin 131 located at the B layer.

[0094] Further, the koji making equipment 100 further comprises an explosion-proof unit 190 for electrical equipment (not shown in the figure). It can be understood that the explosion-proof unit 190 comprises a plurality of explosion-proof cabinets 191 and explosion-proof pipes (not shown in the figure), and the electrical equipment is placed in the explosion-proof cabinet 191 to avoid contact between the dust and the electrical equipment. The electrical equipment needs to be electrically connected with the crushing unit 120, the stirring unit 130, the elevator 140, the first screw conveyor 150 and the second screw conveyor 160 through wires to supply power to the crushing unit 120, the stirring unit 130, the elevator 140, the first screw conveyor 150 and the second screw conveyor 160. The wires need to be arranged in the explosion-proof pipes to avoid contact with the dust and improve safety.

[0095] Please refer to Figure 2 In order to ensure that the staff can open or close the koji making equipment 100 regardless of which floor, an electrical control box is arranged at each floor, and therefore an explosion-proof cabinet 191 is arranged at each floor to protect the battery control box.

[0096] In summary, the koji making equipment 100 drives the containing unit 110 to switch between the feeding position and the discharging position by arranging the elevator 140, and thus the containing unit 110 can move to the discharging position under the driving of the elevator 140 after completing feeding at the feeding position, so that the raw materials can be moved from the containing unit 110 to the crushing unit 120. After receiving the raw materials released by the containing unit 110 at the feeding position, the crushing unit 120 crushes the raw materials and conveys the crushed raw material powder to the stirring unit 130 through the first screw conveyor 150; the stirring unit 130 stirs the raw material powder and water together to make koji. The koji making equipment 100 replaces manual carrying by the elevator 140 and the first screw conveyor 150 to reduce the labor intensity and labor cost of workers and improve the conveying efficiency and the koji making efficiency.

[0097] The above merely illustrates the specific embodiments of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which shall be covered within the protection scope of the present application.
