Description

Technical Field

[0001] This invention belongs to the field of starch processing technology, and in particular relates to a continuous crushing device for starch raw materials. Background Technology

[0002] Starch is a high-molecular-weight carbohydrate, a polysaccharide formed by the polymerization of glucose molecules. The main raw materials for starch include plants such as corn, potatoes, wheat, sweet potatoes, and cassava. Among them, corn, potatoes, and sweet potatoes are the most frequently used as raw materials for starch, and they also contain a relatively high amount of starch.

[0003] The existing technology (patent application CN108160279B, entitled "A Sweet Potato Crushing Device for Sweet Potato Starch Production") is highly practical and very convenient to use. It can quickly and easily crush sweet potatoes for sweet potato starch production and processing, and accurately crush them into pieces suitable for subsequent processing, greatly improving the daily production efficiency and development of sweet potato starch production enterprises. However, in the process of implementing this technical solution, at least the following problems were found in the existing technology: In the process of processing starch raw materials such as corn, potatoes and sweet potatoes into starch, it is necessary to crush these three starch raw materials in advance. Since their shapes, diameters and other characteristics are different, three different crushing equipment are usually used for corresponding crushing operations. This not only increases the cost of crushing equipment, but also prolongs the transportation time of starch raw materials and reduces the crushing efficiency of starch raw materials.

[0012] Preferably, the reciprocating assembly includes annular toothed grooves opened on the outer side of three sets of centrifuge cylinders, and drive gears meshing on the inner side of the three sets of annular toothed grooves.

[0015] The continuous crushing device for starch raw materials of the present invention has the following advantages: 1. This continuous crushing device for starch raw materials achieves a primary spiral extrusion crushing effect on corn, potato, and sweet potato starch raw materials entering three sets of feeding cylinders through a crushing component. During this process, a dehydration component first performs heat conduction evaporation dehydration treatment on the starch raw materials in the spiral extrusion crushing state in the three sets of feeding cylinders, which is conducive to the precipitation of starch substances and avoids the moisture in the starch raw materials affecting subsequent crushing operations and causing adhesion.

[0016] 2. This continuous crushing device for starch raw materials uses a chopping component to further refine and crush corn, potato, and sweet potato starch raw materials according to their shape and diameter characteristics, while simultaneously achieving a material guiding and anti-blocking effect. Then, a crushing component centrifuges three sets of centrifugal drums. Under the action of centrifugal force, the impact balls filled inside the three sets of centrifugal drums are forced to impact and crush the starch raw material fragments in the three sets of centrifugal drums, achieving a continuous and efficient crushing effect for corn, potato, and sweet potato starch raw materials and improving the fineness of the crushed starch raw materials.

[0017] 3. This continuous crushing device for starch raw materials drives the extrusion seats on three reciprocating screws to move up and down repeatedly through the reciprocating components and the extrusion components.

[0021] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments: like Figures 1-13 As shown, a continuous starch raw material crushing device of the present invention includes a top cover 1. The bottom of the top cover 1 is fixed with a feeding cylinder 2 with a feeding port sealing cover at a triangular distance. The bottom of the three feeding cylinders 2 is connected to a chopping end 3. The bottom of the three chopping ends 3 is rotated with a centrifuge cylinder 4. The bottom of the three centrifuge cylinders 4 is connected to a crushing end 5. The bottom of the three crushing ends 5 is fixed with a bottom cover 6. A protective frame 17 is fixed on the bottom cover 6 for protecting the three centrifuge cylinders 4 and the crushing end 5. The protective frame 17 provides safety protection for the three centrifuge cylinders 4 in the rotating state to prevent injury. The protective frame 17 is provided with hollow holes to facilitate heat dissipation. The top cover 1 is equipped with a crushing component for primary crushing of different types of starch raw materials in the feeding cylinder 2. The crushing component includes a servo motor 71 fixed in the middle of the top cover 1, a central gear 72 sleeved on the output shaft of the servo motor 71, a differential gear 73 meshing on the outside of the central gear 72, and a spiral extrusion frame 74 embedded in the differential gear 73. A shredding blade 75 is fixed on the spiral extrusion frame 74. The central gear 72 on the servo motor 71 drives the three spiral extrusion frames 74 and the shredding blade 75 to rotate synchronously through the three sets of differential gears 73, so as to achieve a primary spiral extrusion and shredding effect on the corn, potato and sweet potato starch raw materials that arrive in the three sets of feeding cylinders 2. A dehydration assembly for heat-steaming different types of starch raw materials via heat conduction from the crushing component is provided on the top cover 1. The dehydration assembly includes electric heaters 81 fixed on the top cover 1, and rotating seats 82 are fixed to the bottom of the three sets of electric heaters 81. Rotating heads 83, which are connected to three spiral extrusion frames 74, rotate within the rotating seats 82. Heat-conducting cavities 84 are opened within the three spiral extrusion frames 74. Heating rods 85 are longitudinally arranged at the bottom ends of the three sets of electric heaters 81, passing through the rotating seats 82 and rotating heads 83 to reach the heat-conducting cavities 84. Three sets of electric heaters 81 provide heat to the heating rods 85. The three sets of rotating seats 82 and rotating heads 83 provide rotational support between the three spiral extrusion frames 74 and the heating rods 85. The heat generated by the three heating rods 85 is conducted through the heat conduction chambers 84 in the three spiral extrusion frames 74 to the three sets of feeding cylinders 2. This achieves heat conduction, evaporation and dehydration treatment of the starch raw material in the spiral extrusion and crushing state in the three sets of feeding cylinders 2, which is conducive to the precipitation of starch substances and avoids the moisture in the starch raw material from affecting the subsequent crushing operation and causing adhesion. The three sets of shredding blades 75 are designed in an alternating symmetrical manner along the longitudinal axis of the spiral extrusion frame 74. They are used to symmetrically and alternately extrude and shred different types of starch raw materials in the three sets of feeding cylinders 2. The outer side of the three sets of feeding cylinders 2 is provided with a heat preservation groove, and a heat preservation sleeve 14 is installed inside the heat preservation groove to keep the three sets of feeding cylinders 2 warm and delay heat loss.

[0022] The three sets of chopping ends 3 are equipped with chopping components for secondary crushing of different types of starch raw materials. Each chopping component includes a first chopping plate 91, a second chopping plate 92, and a third chopping plate 93 embedded within the three sets of chopping ends 3. The starch raw material fragments in the three sets of feeding cylinders 2, which are compressed by the three spiral extruders 74, are further refined and crushed by the first chopping plate 91, the second chopping plate 92, and the third chopping plate 93. The mesh shape and... The materials have different densities, and guide strips 95 are fixed to the bottom of the three spiral extrusion frames 74 via rotating rods 94 for guiding the first chopping plate 91, the second chopping plate 92, and the third chopping plate 93. The three spiral extrusion frames 74 simultaneously drive the guide strips 95 on the three rotating rods 94 to guide the starch raw material fragments on the first chopping plate 91, the second chopping plate 92, and the third chopping plate 93 to prevent clogging. According to the shape and diameter characteristics of the corn, potato, and sweet potato starch raw materials, they are further refined, extruded, and chopped, and the guiding and anti-clogging effect is achieved simultaneously. Furthermore, each of the three centrifuge cylinders 4 is equipped with a crushing assembly for three-stage crushing of different types of starch raw materials. The crushing assembly includes a connecting shaft 101 fixed to the bottom of three rotating rods 94, and impact balls 102 are filled inside the three centrifuge cylinders 4. Rotating recesses 103 are annularly opened on both the upper and lower sides of each of the three centrifuge cylinders 4, and rotating protrusions 104 are fixedly engaged with the chopping end 3 and the extrusion end 5 within the three rotating recesses 103. With the three rotating recesses 103 and rotating protrusions 104 providing rotational support for the three chopping ends 3 and the extrusion ends 5 and the centrifuge cylinders 4, the materials are simultaneously extruded by the three spirals. The frame 74 drives three sets of centrifuge cylinders 4 to rotate centrifugally at the junction of the three sets of chopping ends 3 and crushing ends 5 via three connecting shafts 101. This rotation causes the impact balls 102 filled inside the cylinders to follow the rotation. Under the action of centrifugal force, the three sets of impact balls 102 are forced to impact and crush the starch raw material fragments inside the three sets of centrifuge cylinders 4. The three sets of screening plates 105 embedded at the bottom of the three sets of centrifuge cylinders 4 screen and feed the crushed starch raw material, thereby achieving continuous and efficient crushing of corn, potato and sweet potato starch raw materials and improving the fineness of the crushed starch raw materials.

[0023] like Figures 10-12 As shown, a reciprocating assembly and a crushing assembly for four-stage crushing of different types of starch raw materials in three sets of crushing ends 5 are provided inside the bottom cover 6. The reciprocating assembly includes annular toothed grooves 111 opened on the outside of the three sets of centrifuge cylinders 4, and a drive gear 112 meshing on the inside of the three sets of annular toothed grooves 111. The bottom of the drive gear 112 is fixed with a main bevel gear 113 that rotates with the bottom cover 6 through a fixed shaft. The annular toothed grooves 111 on the three sets of centrifuge cylinders 4 rotate linearly through the drive gear 112. A bevel gear frame 114 that rotates with the bottom cover 6 meshes on the outside of the main bevel gear 113, and a secondary bevel gear 115 meshes on the outside of the three bevel gear frames 114. The crushing assembly includes reciprocating screws 121 longitudinally mounted on three sets of secondary bevel gears 115. The main bevel gear 113 drives the reciprocating screws 121 on the three sets of secondary bevel gears 115 to rotate via three bevel gear supports 114, and the screws penetrate the bottom cover 6 to the crushing end 5. The outer sides of the three reciprocating screws 121 are threadedly connected to reciprocating screw cylinders 122. A crushing seat 123 that slides with the crushing end 5 is provided on the top of the three reciprocating screw cylinders 122, and a crushing head 124 is circumferentially fixed on the crushing seat 123. A fixing seat 126 is embedded on the top of the three sets of crushing ends 5. The fixing seat 126 has a crushing groove 125 that engages with the crushing head 124 on the side near the crushing seat 123. The fixed base 126 is provided with material leakage holes that are staggered with the crushing trough 125. The starch raw material fragments after being screened by the three sets of sieve plates 105 are fed into the three sets of crushing ends 5 through the material leakage holes on the three sets of fixed bases 126 and are located between the three sets of extrusion seats 123 and the fixed base 126. The three reciprocating screws 121 drive the extrusion seats 123 on the three reciprocating screw barrels 122 to move up and down. The three sets of extrusion seats 123 drive the crushing head 124 to reciprocate and squeeze the crushing trough 125 on the three sets of fixed bases 126 in a fixed state, so as to achieve a further fine crushing effect on the starch raw material fragments falling into the three sets of crushing ends 5, so that the corn, potato and sweet potato starch raw materials are crushed more thoroughly and finely.

[0024] like Figure 13 As shown, during the crushing of corn, potato and sweet potato starch raw materials in the three sets of feeding cylinders 2, in order to better retain the starch, the water in the starch raw materials needs to be removed. The removed water also contains the essence of the starch raw materials, and most of it is directly discharged without negative pressure collection function, so the water essence cannot be recycled. The inner side of the three sets of feeding cylinders 2 is connected to a negative pressure frame 15 that is fixedly matched with the top cover 1. A flow equalization plate 16 is embedded at the connection between the negative pressure frame 15 and the three sets of feeding cylinders 2. The negative pressure frame 15 is equipped with a collection component for the evaporation and recovery of water in the three sets of feeding cylinders 2. The collection component includes a suction fan 131 fixed to the output shaft of the servo motor 71 through a coupling. The servo motor 71 drives the suction fan 131 to rotate in the negative pressure frame 15. Under the action of negative pressure suction, the steam generated by the heat conduction dehydration of the starch raw materials is forced to pass through the flow equalization plate 16 to the negative pressure frame 15. A collection vessel 133 is threadedly connected to the bottom of the negative pressure frame 15 via an electrically controlled valve 132, and a lid 134 is threadedly connected to the bottom of the collection vessel 133. A level probe 135 is vertically placed on the lid 134 to monitor the level of the condensate in the collection vessel 133. The condensate flows down from the opened electrically controlled valve 132 and is collected in the collection vessel 133. The level probe 135 on the lid 134 monitors the level of the condensate in the collection vessel 133 in real time, so that the collection vessel 133 can be unscrewed and the lid 134 can be opened in time to clean the condensate. The steam generated during the dehydration of starch raw materials in the three sets of cloth cylinders 2 is collected so as to recover and reuse the steam substances released from corn, potato and sweet potato starch raw materials and avoid wasting the water essence.

[0025] The working principle of a continuous starch raw material crushing device is as follows: First, the central gear 72 on the servo motor 71 drives three spiral extrusion frames 74 and the shredding blades 75 to rotate synchronously through three sets of differential gears 73, achieving a primary extrusion and shredding effect on the corn, potato, and sweet potato starch raw materials entering the three sets of feeding cylinders 2. During this process, three sets of electric heaters 81 provide heat to the heating rods 85, and the three sets of rotating seats 82 and rotating heads 83 provide rotational support between the three spiral extrusion frames 74 and the heating rods 85. Then, the heat generated by the three heating rods 85 is conducted through the heat conduction chambers 84 in the three spiral extrusion frames 74 to the three sets of feeding cylinders 2, thus crushing the starch raw materials in the spiral extrusion and shredding state within the three sets of feeding cylinders 2. The heat conduction evaporation dehydration process facilitates the precipitation of starch substances within the raw materials, preventing moisture in the starch raw materials from affecting subsequent crushing operations and causing adhesion. During the dehydration of the starch raw materials in the three sets of feeding cylinders 2, the servo motor 71 drives the suction fan 131 to rotate within the negative pressure frame 15. Under the action of negative pressure suction, the steam generated by the heat conduction dehydration of the starch raw materials is forced to pass through the flow equalization plate 16 to reach the negative pressure frame 15, and then flows down through the opened electronic control valve 132 to collect in the collection pot 133. The liquid level probe 135 on the pot cover 134 monitors the liquid level of the steam condensate collected in the collection pot 133 in real time, so that the collection pot 133 can be unscrewed and the pot cover 134 can be opened in time to clean the collected condensate. Next, based on the shape and diameter characteristics of the corn, potato, and sweet potato starch raw materials, the starch raw material fragments in the three sets of feeding cylinders 2, which are being squeezed by the three spiral extruders 74, are further refined and crushed by the first crushing plate 91, the second crushing plate 92, and the third crushing plate 93. Simultaneously, the guide strips 95 on the three rotating rods 94 guide the starch raw material fragments on the first crushing plate 91, the second crushing plate 92, and the third crushing plate 93 to prevent clogging. Then, the three sets of rotating notches 103 and rotating convex ends 104 guide the three sets of crushing ends 3 and the extruders... With the crushing end 5 and the centrifuge cylinder 4 providing rotational support, three spiral extrusion frames 74 drive three sets of centrifuge cylinders 4 through three connecting shafts 101 to centrifuge at the junction of the three sets of crushing ends 3 and extrusion ends 5. This also drives the impact balls 102 filled inside to rotate. Under the action of centrifugal force, the three sets of impact balls 102 are forced to impact and crush the starch raw material fragments in the three sets of centrifuge cylinders 4. The material is then screened and discharged through three sets of sieve plates 105, achieving continuous and efficient crushing of corn, potato and sweet potato starch raw materials and improving the fineness of the crushed starch raw materials. Finally, the starch raw material fragments, after being screened and discharged by the three sets of sieve plates 105, are discharged through the discharge holes on the three sets of fixed seats 126 into the three sets of crushing ends 5, and are located between the three sets of extrusion seats 123 and the fixed seats 126. At the same time, the annular toothed grooves 111 on the three sets of centrifugal cylinders 4, which rotate centrifugally, drive the main bevel gear 113 to rotate linearly through the drive gear 112. The main bevel gear 113 drives the reciprocating screws 121 on the three sets of secondary bevel gears 115 to rotate through the three bevel gear frames 114. The three reciprocating screws 121 drive the three reciprocating screw cylinders 12 The extrusion seat 123 on the 2nd reciprocates and moves up and down. The three sets of extrusion seats 123 drive the crushing head 124 to reciprocate and squeeze the crushing groove 125 on the three sets of fixed seats 126 in a fixed state, so as to achieve further fine crushing of starch raw material fragments falling into the three sets of crushing ends 5, making the corn, potato and sweet potato starch raw materials crushed more thoroughly and finely. After the corn, potato and sweet potato starch raw materials in the three sets of crushing ends 5 are crushed, the feeding cover on the outside of the three sets of crushing ends 5 is opened to take out the starch raw material fragments inside for the next grinding and processing operation.

[0026] It should be noted that the specific models and specifications of the servo motor 71, electric heater 81, heating rod 85, electric control valve 132 and liquid level probe 135 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0027] The power supply circuits for the servo motor 71, electric heater 81, heating rod 85, electric control valve 132, and liquid level probe 135 are clear to those skilled in the art and will not be described in detail here.
