Description

Technical Field

[0001] This invention belongs to the field of wine processing technology, and specifically relates to a quantitative feeding device for raw materials in wine processing. Background Technology

[0002] With the rapid development of industrialized food processing and intelligent manufacturing equipment, the processing of alcoholic beverages is transforming and upgrading towards large-scale, standardized, and intelligent production. Precise ingredient feeding is a core process for ensuring consistent taste, quality, and compliance in alcoholic beverage production. Currently, many small and medium-sized wineries still rely on manual or semi-automated ingredient feeding methods, feeding basic raw materials (various crushed grains such as sorghum, wheat, rice, glutinous rice, and corn) into processing equipment. Different grain types and proportions directly affect the taste, aroma, and mouthfeel of the liquor. Traditional ingredient feeding equipment has low levels of intelligence, generally suffering from poor feeding accuracy and large deviations in material proportions. Furthermore, manual feeding is labor-intensive, inefficient, and prone to introducing impurities, posing food safety risks and failing to meet the demands of modern industrialized mass production of alcoholic beverages. Therefore, developing a high-precision, intelligent quantitative ingredient feeding device suitable for alcoholic beverage processing is an urgent need to fill the industry's equipment gaps and promote intelligent manufacturing upgrades in the alcoholic beverage processing sector. Summary of the Invention

[0003] The purpose of this invention is to provide a simple and reasonably designed quantitative feeding device for processing raw materials of wine products in order to solve the above problems.

[0004] The present invention achieves the above objectives through the following technical solutions: A quantitative feeding device for raw materials in wine processing includes: Storage hopper, used to store raw materials that have undergone crushing and pretreatment; The screw conveyor mechanism, located below the storage hopper, is used to quantitatively transport raw materials to the grain moistening area; The material loosening mechanism includes a support assembly, pressure rings, an elastic inner lining, a first air bladder, a first air supply pipe, and a first air compressor. The first air compressor is connected to the first air bladder through the first air supply pipe. The first air bladder is fixedly disposed inside the conical section of the storage hopper, and the elastic inner lining is disposed outside the first air bladder. Multiple pressure rings are assembled on the outside of the elastic inner lining, and the pressure rings are fixedly supported by the support assembly. When the first air bladder expands, the elastic inner lining adheres to the first air bladder and bulges towards the center of the conical section. When the first air bladder contracts, the elastic inner lining returns to its original position.

[0005] Preferably, the support assembly includes support rods, a main shaft, and a frame plate. The frame plate is fixedly mounted on the upper end of the storage hopper, the main shaft is fixedly mounted on the frame plate, and multiple sets of support rods are provided. One end of each set of support rods is fixedly connected to a corresponding pressure ring, and the other end of each set of support rods is fixedly connected to the outer wall of the main shaft.

[0006] Preferably, when the first airbag inflates, the longitudinal section of the first airbag located below the pressure ring is triangular, and the length of the lower side of the longitudinal section of the triangle is greater than the length of the upper side.

[0007] Preferably, the angle between the support rod and the main shaft gradually decreases from top to bottom along the axis of the main shaft.

[0008] Preferably, a tapered column is fixedly provided at the lower end of the main shaft, and air chambers that communicate with each other are respectively opened in the tapered column and the main shaft. An air hole is opened on the side of the tapered column, and a second air bag is installed on the outside of the tapered column. The second air bag communicates with the air chamber through the air hole. A second air compressor is provided on the outside of the storage hopper, and the output end of the second air compressor communicates with the air chamber in the main shaft through a second air supply pipe.

[0009] Preferably, when the first airbag is in a contracted state, the second airbag is in an inflated state.

[0010] Preferably, the second airbag is inflated when the first airbag is inflated.

[0011] Preferably, the screw conveying mechanism includes a conveying cylinder, a screw conveying shaft, a drive motor, an inlet pipe, and an outlet pipe. The screw conveying shaft is rotatably installed in the conveying cylinder, and the edge of the screw conveying shaft's screw pusher blades is in frictional contact with the inner wall of the conveying cylinder. The drive motor is installed outside the conveying cylinder and is connected to the input end of the screw conveying shaft. The inlet pipe is installed at the inlet end of the conveying cylinder and communicates with the conveying cylinder. The outlet pipe is installed at the outlet end of the conveying cylinder and communicates with the conveying cylinder.

[0012] Preferably, a transition pipe is fixedly installed at the lower end of the storage hopper, and a discharge pipe is provided between the transition pipe and the feed pipe. The transition pipe, the discharge pipe and the feed pipe are sequentially sealed and connected. An agitator is rotatably installed inside the discharge pipe. The input end of the agitator extends through the part outside the discharge pipe and is fixedly connected to a main pulley. The output end of the drive motor is also connected to a secondary pulley. A drive belt is sleeved on the main pulley and the secondary pulley. The drive belt passes through the clearance hole of the conveying cylinder and is sleeved with the secondary pulley.

[0013] Preferably, the upper end of the conveying cylinder is hinged with a maintenance cover. When the conveying cylinder is in a quantitative conveying state, the maintenance cover is in a closed state, and the contact point between the maintenance cover and the conveying cylinder is sealed.

[0014] The present invention has at least the following beneficial effects: The present invention provides a quantitative feeding device for raw materials in wine processing, which is equipped with a storage hopper, a screw conveyor mechanism and a loosening mechanism. The screw conveyor mechanism automatically feeds the pre-processed raw materials in the storage hopper into the grain moistening equipment. Moreover, the loosening mechanism includes a support component, a pressure ring, an elastic inner lining, a first air bladder, a first air supply pipe and a first air compressor. Through the alternating transformation of the contraction and expansion states of the first air bladder, the elastic inner lining arranged outside the first air bladder repeatedly pushes and drops the raw materials, destroys the friction and compression balance between the crushed raw materials, breaks up the material clumps and material arches from the root, and eliminates the problem of interruption of feeding and machine stoppage. Furthermore, when the first airbag inflates, the longitudinal section of the first airbag located below the pressure ring is triangular, and the length of the lower side of the longitudinal section of the triangle is greater than the length of the upper side. With the help of the first airbag structure, the raw material is lifted upward, and the elastic inner lining cloth that is lifted on the outside has a greater tensile deformation at the bottom than at the top. This allows the elastic inner lining cloth itself to lift the raw material on the surface. After the first airbag contracts, it causes the lifted raw material to fall, increasing the degree of disturbance of the raw material. In addition, a second airbag is installed on the cone column at the lower end of the main shaft. The second airbag is evacuated and inflated by the second air compressor, so that the second airbag alternates between the contracted state and the expanded state. The first airbag and the second airbag are in different states. The alternating pushing of the material by the two sets of airbags causes the material in the cone section to periodically reciprocate bidirectionally, continuously destroying the interparticle adhesion and cutting off the stable arch support structure.

[0017] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

They are only used to facilitate the description of this application and simplify the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0019] like Figure 1 , Figure 2 and Figure 3 As shown, the present invention provides a quantitative feeding device for raw materials in wine processing, comprising: Storage hopper 2 is used to store raw materials that have undergone crushing and pretreatment. The screw conveyor 1 is located below the storage hopper 2 and is used to quantitatively transport raw materials to the grain moistening area. The loosening mechanism 3 includes a support assembly, a pressure ring 38, an elastic inner lining 37, a first air bladder 36, a first air supply pipe 32, and a first air compressor 31. The first air compressor 31 is connected to the first air bladder 36 through the first air supply pipe 32. The first air bladder 36 is fixedly disposed inside the conical part of the storage hopper 2, and the elastic inner lining 37 is disposed outside the first air bladder 36. Multiple pressure rings 38 are assembled on the outside of the elastic inner lining 37. The pressure rings 38 are fixedly supported by the support assembly. When the first air bladder 36 inflates, the elastic inner lining 37 adheres to the first air bladder 36 and bulges towards the center of the conical part. When the first air bladder 36 contracts, the elastic inner lining 37 returns to its original position.

[0020] Multiple pressure rings 38 initially limit the elastic inner lining 37 to the inner side of the cone-shaped portion of the storage hopper 2. The raw materials for pre-processing and crushing are pressed onto the elastic inner lining 37. Under the blowing action of the first air compressor 31, the first air bladder 36 expands. The expanded first air bladder 36 lifts the elastic inner lining 37 to lift the raw materials outside the inner lining 37. Under the suction action of the first air compressor 31, the first air bladder 36 contracts, and the pushed raw materials fall down. The elastic inner lining 37, under its own elastic reset, presses the contracted first air bladder 36 back onto the inner side of the cone-shaped portion of the storage hopper 2. The above actions are repeated to achieve repeated pushing and falling of the raw materials, thereby disrupting the friction and compression balance between the crushed raw materials, breaking up material clumps and material arches from the source, and preventing the problem of material feeding interruption and machine stoppage.

[0021] Among them, the storage hopper 2 uses food-grade 304 stainless steel as the main structural material, which meets the hygiene standards for liquor brewing and food production. All parts that come into direct contact with the grain raw materials are mirror-polished. Figure 2 and Figure 3 The structure is illustrated. The inner side of the conical part of the storage hopper 2 is provided with an elastic inner lining cloth 37. In order to increase the storage volume of the storage hopper 2, a straight cylindrical part is provided at the upper end of the conical part. This part will be in direct contact with the raw materials. After the inner wall of this part is polished, there are no dead corners and it is not easy for materials to accumulate. This avoids the long-term adhesion of grain powder and the growth of mold, thus meeting the food safety access standards of the liquor production workshop.

[0022] It should be noted that grain conditioning is a crucial step in the preparation of general solid-state grain liquor. Grain conditioning involves pre-crushing and pre-treating various grain raw materials, and then quantitatively feeding them into the conditioning equipment according to the required proportions. Furthermore, it should be explained that the storage hopper 2, screw conveyor mechanism 1, and loosening mechanism 3 mentioned in this embodiment are a single set of equipment. In practical applications, the same number of sets of equipment can be set up according to the types and quantities of raw materials used in solid-state grain liquor production to quantitatively feed different raw materials according to the proportions. Conventional multi-grain liquor production requires five raw materials: sorghum, rice, glutinous rice, wheat, and corn. Five sets of this feeding device can be arranged in parallel on the production line. The discharge pipes 15 of each device converge into a unified grain conditioning mixing tank. The electrical control system controls the conveying time of each screw conveyor mechanism 1, precisely matching the process formula proportions, achieving synchronous automatic proportioning and feeding of multiple raw materials. This completely replaces manual weighing and manual feeding processes, significantly reducing human error and labor intensity, and achieving a high degree of automation.

[0023] For example, see [link to relevant documentation]. Figure 3 and Figure 6 The support assembly includes support rods 35, a main shaft 34, and a frame plate 33. The frame plate 33 is fixedly mounted on the upper end of the storage hopper 2, and the main shaft 34 is fixedly mounted on the frame plate 33. Multiple sets of support rods 35 are provided, with one end of each set of support rods 35 fixedly connected to a corresponding pressure ring 38, and the other end of each set of support rods 35 fixedly connected to the outer wall of the main shaft 34. This fixes the multiple pressure rings 38 relative to the storage hopper 2. It should be noted that the ring diameter of the multiple pressure rings 38 is adaptively set according to the inner diameter of the conical section of the storage hopper 2; that is, the ring diameters of the multiple pressure rings 38 are different. Figure 3 As shown, the ring diameters of the multiple pressure rings 38 decrease sequentially from top to bottom. The frame plate 33 adopts a detachable bolt fixing structure. During routine maintenance and replacement of the elastic inner lining cloth 37 and the first air bag 36, the frame plate 33 can be directly disassembled, and the main shaft 34, support rod 35, and all pressure rings 38 can be lifted upwards and lifted out of the storage hopper 2 as a whole, without the need to enter the equipment for cleaning, making maintenance operations convenient.

[0024] For example, see [link to relevant documentation]. Figure 3 When the first airbag 36 inflates, the longitudinal section of the first airbag 36 located below the pressure ring 38 (with...) Figure 3For example, the cross-section along the axis of the main shaft 34 is triangular, and the length of the lower side of the longitudinal section of the triangle is greater than the length of the upper side. The base of the longitudinal section of the triangle is located at the inner wall of the storage hopper 2. It should be noted that the triangle here is an approximate shape. During the expansion of the first airbag 36, the raw material is lifted by the special structure of the first airbag 36. After the first airbag 36 expands, the longitudinal section is a triangle with a longer lower side and a shorter upper side. This makes the elastic inner lining 37 that is lifted on the outside more tensile at the bottom than at the top. This stretching of the elastic inner lining 37 lifts the raw material on the surface. After the first airbag 36 contracts, the lifted raw material falls, increasing the disturbance of the raw material.

[0025] It should be noted that, with Figure 3 For example, there are three pressure rings 38. Therefore, the triangular part of the longitudinal section of the first airbag 36 has three parts. In other embodiments, the number of pressure rings 38 is two, four, etc., which is not limited.

[0026] Among them, such as Figure 3 As shown, the angle between the support rod 35 and the main shaft 34 gradually decreases from top to bottom along the axis of the main shaft 34. Through the inclined support rod 35, while supporting the pressure ring 38, the raw material above is laterally diverted along the inclined support rod 35 under the action of gravity, eliminating voids in the middle and ensuring continuous material feeding.

[0027] For example, see [link to relevant documentation]. Figure 3 and Figure 4 A tapered column 306 is fixedly installed at the lower end of the main shaft 34. Air chambers 303 are respectively opened inside the tapered column 306 and the main shaft 34, communicating with each other. Air holes 305 are opened on the side of the tapered column 306. A second airbag 304 is installed on the outside of the tapered column 306, and the second airbag 304 communicates with the air chambers 303 through the air holes 305. Figure 6 As shown, multiple air holes 305 are evenly arranged around the conical column 306 to ensure that the second airbag 304 expands uniformly in all directions when inflated, without local bulging, deformation, or air leakage. A second air compressor 301 is installed outside the storage hopper 2, and the output end of the second air compressor 301 is connected to the air chamber 303 inside the main shaft 34 through a second air supply pipe 302. Under the suction and blowing action of the second air compressor 301, the second airbag 304 alternately contracts and expands, breaking up the arches of the raw material at the center of the conical section of the storage hopper 2.

[0028] For example, the states of the first airbag 36 and the second airbag 304 are different; see further. Figure 5When the first airbag 36 is in a contracted state, the second airbag 304 is in an expanded state, causing the raw material in the conical part of the storage hopper 2 to be pushed towards the elastic inner lining cloth 37. When the first airbag 36 is in an expanded state, the second airbag 304 is in a contracted state, causing the raw material in the conical part of the storage hopper 2 to be pushed away from the elastic inner lining cloth 37. The alternating pushing of the raw material by the two sets of airbags causes the raw material in the conical part to periodically reciprocate bidirectionally, continuously destroying the interparticle adhesion and cutting off the stable arched support structure.

[0029] In another embodiment, the first airbag 36 and the second airbag 304 are in the same state. For example, when the first airbag 36 is inflated, the second airbag 304 is inflated, and when the first airbag 36 is contracted, the second airbag 304 is also contracted. This makes the material pushed by the expansion of the two sets of airbags suspended on both sides after the two sets of airbags contract. Under the action of gravity, the material loosens and collapses, effectively avoiding the occurrence of arching.

[0030] It should be noted that, as Figure 1 As shown, the storage hopper 2 is fixedly mounted on the base 4, as... Figure 2 As shown, the first air compressor 31 and the second air compressor 301 are respectively fixedly mounted on the base 4.

[0031] For example, both the first airbag 36 and the second airbag 304 are made of food-grade double-layer composite rubber, with the inner layer being airtight and the outer layer being wear-resistant and resistant to powder friction.

[0032] Moreover, the elastic inner lining cloth 37 is made of food-grade matte silicone fabric with a surface densely covered with micro-protruding elastic soft barbs. When the first airbag 36 pushes the elastic inner lining cloth 37 inward, the soft barbs insert into the material layer, actively breaking up clumps and crushing small material clumps. For example, the height of the soft barbs is controlled at 1~2mm, so as not to excessively entangle the grain particles, while having sufficient piercing and breaking ability. When the first airbag 36 deflates, the soft barbs rebound when the elastic inner lining cloth 37 rebounds, simultaneously shaking off the powder and grain powder adhering to the cloth surface, thus achieving self-cleaning.

[0033] Continue reading Figure 7The screw conveyor mechanism 1 includes a conveying cylinder 12, a screw conveying shaft 13, a drive motor 16, an inlet pipe 11, and an outlet pipe 15. The screw conveying shaft 13 is rotatably mounted in the conveying cylinder 12, and the edge of the screw conveying shaft 13's screw pusher blades is in frictional contact with the inner wall of the conveying cylinder 12. The drive motor 16 is mounted outside the conveying cylinder 12 and is connected to the input end of the screw conveying shaft 13. The inlet pipe 11 is mounted at the inlet end of the conveying cylinder 12 and communicates with the conveying cylinder 12. The outlet pipe 15 is mounted at the outlet end of the conveying cylinder 12 and communicates with the conveying cylinder 12. It should be noted that the drive motor 16 is a variable frequency motor to adjust the speed of the screw conveying shaft 13, and volumetric metering is achieved by relying on the pitch of the screw blades of the conveying shaft 13 and the conveying volume.

[0034] Continue reading Figure 3 and Figure 8 A transition pipe 21 is fixedly installed at the lower end of the storage hopper 2. A discharge pipe 110 is provided between the transition pipe 21 and the feed pipe 11. The transition pipe 21, the discharge pipe 110 and the feed pipe 11 are sequentially sealed and connected. A stirring blade 19 is rotatably installed inside the discharge pipe 110. The input end of the stirring blade 19 is fixedly connected to the main pulley 18 through the part outside the discharge pipe 110. The output end of the drive motor 16 is also connected to a secondary pulley. The secondary pulley is set in the conveying cylinder 12. A transmission belt 17 is sleeved on the main pulley 18 and the secondary pulley. The transmission belt 17 passes through the clearance hole of the conveying cylinder 12 and is sleeved on the secondary pulley. It should be noted that the area in the conveying cylinder 12 where the secondary pulley is installed is isolated from the area where the screw conveyor shaft 13 is installed. That is, the transmission of the secondary pulley and the transmission belt 17 will not affect the conveying of the crushed material. The falling fragments are pushed into the feed pipe 11 by the stirring blade 19, so as to achieve stable material discharge between the storage hopper 2 and the conveying cylinder 12.

[0035] Continue reading Figure 7 The upper end of the conveying cylinder 12 is hinged with a maintenance cover 14. When the conveying cylinder 12 is in a quantitative conveying state, the maintenance cover 14 is in a closed state, and the contact point between the maintenance cover 14 and the conveying cylinder 12 is sealed. For example, a sealing ring is embedded on the maintenance cover 14 at the contact point with the conveying cylinder 12 to prevent the fragments from being squeezed out of the maintenance cover 14 when conveying fragments. Opening the maintenance cover 14 facilitates the maintenance of the screw conveyor shaft 13.

[0036] It should be noted that, in use, the quantitative feeding device for raw materials in wine processing stores various raw materials to be pre-processed into their respective storage hoppers 2. When quantitative feeding of raw materials is carried out according to the ratio of a certain raw material, the raw material in the storage hopper 2 enters the conveying cylinder 12 through the transition pipe 21, the discharge pipe 110 and the inlet pipe 11. Under the drive of the drive motor 16, the screw conveyor shaft 13 rotates to feed the required quantitative amount of raw material from the discharge pipe 15 into the grain moistening equipment. In order to prevent bridging of the crushed material in the storage hopper 2 and ensure smooth feeding, the first air compressor 31 is started and air is blown into the first air bag 36 through the first air supply pipe 32, causing the first air bag 36 to expand, thereby pushing the crushed material in the cone section of the storage hopper 2. When the first air compressor 31 evacuates air from the first air bag 36, the first air bag 36 contracts. The repeated expansion and contraction of the first air bag 36 realizes the repeated inward pushing and falling of the material. Furthermore, the second air compressor 301 is started, and air is blown into the second air bag 304 through the second air supply pipe 302, causing the second air bag 304 to expand. When the second air compressor 301 evacuates air from the second air bag 304, the second air bag 304 contracts. The expansion and contraction actions of the first air bag 36 are repeated to achieve repeated outward pushing and falling of the raw material, so as to achieve bidirectional pushing of the crushed raw material in the cone section of the storage hopper 2, to destroy the friction and compression balance between the crushed raw materials, to break up the material clumps and material arches from the source, and to prevent the problem of material feeding interruption and machine shutdown.

[0037] The above-described embodiments are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of protection of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
