Description

Technical Field

[0001] The invention relates to the technical field of rice noodle processing, in particular to grinding equipment for an automatic rice noodle production line. Background Art

[0002] Rice noodles, a Chinese specialty snack, are a very popular delicacy in southern China. Rice noodles are made from rice and are made into strips or silky rice products through soaking, steaming, and layering, rather than the powdery materials made from rice as the raw material. Rice noodles are flexible and elastic. They do not become mushy when boiled in water and are not easy to break when stir-fried. They are smooth and tasty when boiled or stir-fried with various vegetables or soup ingredients. They are deeply loved by consumers (especially southern consumers). There are many varieties of rice noodles, which can be divided into row rice noodles, square rice noodles, corrugated rice noodles, silver rice noodles, wet rice noodles and dry rice noodles. Their production processes are similar, generally: rice-washing-soaking-grinding-steaming-sheeting (squeezing)-re-steaming-cooling-drying-packaging-finished products. Traditional rice noodle production is manual or semi-mechanical, with low production efficiency, large demand for operators, and unstable process parameters through human control, which cannot meet people's growing quality and quantity needs.

[0003] The Chinese invention patent (CN201710981387.7) discloses a large-scale multifunctional complete set of rice noodle production equipment. It includes a rice elevator discharge port, a rice elevator, a fermentation tank, a rice feeder, a rice noodle discharge port, an auxiliary material machine, a continuous material conveyor, a discharge port, a self-cooking forming machine conveyor belt, a hot water circulation tank, a noodle feeder, an extruder, an aging machine conveyor belt, a fan, an aging machine, a primary loosening machine, a steaming machine, a discharge tank, a secondary loosening machine, a conveyor belt, a feed port, an inner bagging machine, a conveyor belt I, a weighing machine, a metal detector, a conveyor belt II, a sterilizer and a powder picking machine. The rice enters the fermentation tank through the elevator at the rice elevator discharge port, and enters the rice feeder through the rice elevator after fermentation or direct soaking and cleaning, and then enters the auxiliary material machine and the powder picking machine from the rice noodle discharge port. The auxiliary materials are mixed, and after mixing, they are conveyed through a continuous material conveyor and then through a discharge port to the conveyor belt of the self-cooking forming machine, and then to the noodle feeder. The noodle feeder is connected to the extruder. There is a hot water circulation tank around the noodle feeder and the extruder to heat the materials. The rice noodles coming out of the extruder are quickly cooled by the fan and enter the aging machine through the aging machine conveyor belt for aging. The rice noodles are loosened by the primary loosening machine and then enter the steaming machine. After passing through the discharge trough, the rice noodles enter the secondary loosening machine to loosen the rice noodles. After the secondary loosening, the rice noodles enter the inner packaging machine through the conveyor belt to cut and package the rice noodles. After packaging, the rice noodles pass through the conveyor belt I and pass through the weighing instrument, metal detector, conveyor belt II, sterilizer, and powder picking machine in sequence to obtain the final qualified product.

[0004] The above invention realizes the automatic production of rice noodles and improves the production efficiency of rice noodles to a certain extent. However, there are still many shortcomings. For example, the rice feeder, continuous material conveyor and other grinding equipment are concentrated in a large grinding device for grinding, the rice grains are rough and have a poor taste, and the equipment is not convenient to disassemble and clean every day. When the equipment fails or is found to be not cleaned, the entire line needs to be stopped for maintenance, which seriously affects the production efficiency of rice noodles and the taste of the output rice noodles. Summary of the invention

[0005] 1. Technical issues to be resolved

[0006] In order to solve the problem of low production efficiency caused by the need to stop production and repair the entire line due to the failure of grinding equipment in the production process of rice noodle automation equipment, the present invention provides a grinding equipment for an automatic rice noodle production line, which can complete local repairs to ensure output without completely stopping production. At the same time, multiple grinding devices are small in size and easy to disassemble and clean, and the rice grains are evenly dispersed and finely ground to make the finished rice noodles taste better.

[0007] (II) Technical solution

[0008] To achieve the above object, the present invention provides the following technical solutions:

[0009] Provided is a grinding device for an automatic rice noodle production line, comprising a silo, a plurality of parallel grinding devices and a plurality of parallel material guide troughs arranged from top to bottom, wherein the silo comprises a feeding part and a discharging part, wherein the feeding part is located at the upper half of the silo and forms a V-shaped long groove with a large opening facing upward, and the lower end of the feeding part is connected to the discharging part, and the discharging part is divided into a plurality of parallel feeding ports, wherein the grinding device is located below the discharging part, and the grinding device is provided with a material inlet and a material outlet, wherein the material inlet of each grinding device receives material from a corresponding feeding port, and the material guide trough is arranged below the material outlet of each grinding device and can be easily disassembled.

[0010] Preferably, a horizontal dividing screw rod parallel to the long groove edge of the feeding part is provided in the feeding part, and the dividing screw rod comprises a long axis main body and spiral blades. Both ends of the long axis main body are connected to the feeding part through bearings, and the long axis main body is driven to rotate around the axis center line by a motor from the outside. The spiral blades are distributed on the long axis main body in sheet-like manner and at intervals.

[0011] Furthermore, the spiral leaves do not completely cover the long axis body, and there are no spiral leaves in the middle and at both ends of the long axis body.

[0012] Furthermore, the spiral leaves are distributed in a mirror-symmetrical manner relative to the center of the long axis body, that is, one side separated by the center is in a clockwise direction, and the other side is in a counterclockwise direction.

[0013] Preferably, a centralizing trough is provided below the material guiding trough, and the centralizing trough is a long trough-shaped box body with an opening on the top, which can centrally deliver all materials to subsequent processes.

[0014] Furthermore, the concentrated tank is connected to a feed pump, and the feed pump is provided with a feed pipe and a discharge pipe. The feed pipe is connected to the concentrated tank, and the discharge pipe is connected to the next process. A reflux pipe is connected between the discharge pipe and the feed pipe, and the reflux pipe is used to adjust the feed flow rate of the discharge pipe.

[0015] Preferably, the material is fed into the silo by a conveyor belt to avoid the potential malfunction of the equipment caused by the traditional screw feeding method whereby the dough-like material precipitates and aggregates on the screw and is difficult to clean and deteriorates.

[0016] When the grinding equipment is running, the material is fed into the feed section of the silo through a conveyor belt, usually from the middle of the feed section. A portion of the material falls directly into the feed port in the middle of the discharge section, and the other portion of the material is divided by the spiral leaves on the rotating material distribution screw rod to the two ends of the discharge section and falls into the feed ports on both sides from the intervals between the spiral leaves. Therefore, each feed port can be allocated a uniform amount of material and sent to the grinding device below it for fine grinding. After being sent to their respective corresponding guide troughs from the material outlet of the grinding device, they are concentrated and collected in the concentrated trough, and finally pumped up by the feed pump and sent to the next process. When a grinding device is found to have a fault or the rice quality after grinding does not meet the standard, the maintenance personnel only need to remove the guide trough to prevent the substandard rice slurry from flowing into the concentrated trough, adjust the flow of the feed pump, and then adjust or repair the grinding device. This process does not affect the normal production of other grinding devices, thereby improving the finishing production efficiency.

[0017] (III) Beneficial effects

[0018] Compared with the existing known technology, the technical solution of the present invention has the following significant effects:

[0019] 1. Compared with the traditional screw rod conveying, the conveyor belt feeding and feeding bin can avoid the sedimentation and aggregation of dough materials on the screw rod, which is difficult to clean and deteriorates, causing equipment blockage and failure; 2. The segmented spiral blade structure with a middle bare rod can evenly disperse the materials sent from the middle of the conveyor belt to all the feed ports on both sides; 3. There are multiple grinding and conveying paths composed of multiple groups of parallel feeding ports, grinding devices, and guide troughs. When a certain path fails, only the guide trough needs to be removed to repair this single path, and the normal production of other paths will not be affected; 4. Compared with the traditional centralized large-scale grinding device, the multiple small grinding devices in the present invention can achieve fine grinding of dispersed materials, and the grinding effect is better and the taste of the finished rice noodles is better.
