Description

TECHNICAL FIELD

[0001] The utility model relates to grain processing technical field especially relates to a grain processing production line. BACKGROUND

[0002] Grain processing refers to the operating activities of converting raw grain into semi-finished grain, finished grain, or converting semi-finished grain into finished grain. The main grains in the world are rice, wheat, rye, sorghum, corn and millet. These grain crops usually contain various impurities after harvesting and need to be processed before being packaged into grain products for sale to people. However, the current grain processing production line does not process raw grain delicately, which leads to incomplete impurity treatment and affects the quality of packaged grain. SUMMARY

[0003] The utility model provides a grain processing production line, which can process grain through multiple processes to treat impurities more completely and improve the quality of packaged grain.

[0004] The utility model adopts the technical scheme of providing a grain processing production line, which comprises a first impurity removal unit, a second impurity removal unit, a third impurity removal unit, a bacteria removal unit and a finished product storage unit arranged in sequence.

[0005] The first impurity removal unit comprises a receiving bin, and a raw material bin is connected to the receiving bin. A first conveyor for conveying materials is connected between the receiving bin and the raw material bin. A first dust remover for removing dust from the conveyed materials is connected between the receiving bin and the raw material bin.

[0006] The second impurity removal unit comprises a compound specific gravity cleaner connected to the raw material bin through a second conveyor. A first impurity storage bin is connected to the compound specific gravity cleaner through a third conveyor at the impurity discharge end of the compound specific gravity cleaner. A sizing screen is connected to the compound specific gravity cleaner through a fourth conveyor at the discharge end of the compound specific gravity cleaner. A second impurity storage bin is connected to the sizing screen through a fifth conveyor at the impurity discharge end of the sizing screen. A second dust remover for removing dust from the conveyed materials is connected between the sizing screen and the second impurity storage bin.

[0007] The third impurity removal unit comprises a magnetic separator connected to the discharge end of the sizing screen through a sixth conveyor. A stone removal machine is connected to the discharge end of the magnetic separator through a seventh conveyor. A third dust remover for removing dust from the materials is connected to the stone removal machine.

[0008] The bacteria removal unit comprises a microwave sterilization machine connected to the discharge end of the stone removal machine.

[0009] The finished product storage unit comprises a finished product bin connected to the discharge end of the microwave sterilization machine through a finished product conveyor.

[0010] To further optimize this technical solution, the dust outlets of the primary, secondary, and tertiary dust collectors in a grain processing production line are all connected to the input end of a pulse pneumatic conveyor.

[0011] To further optimize this technical solution, the third conveyor in a grain processing production line is a Z-type elevator.

[0012] To further optimize this technical solution, a packaging scale is connected to the discharge port of the finished product warehouse of a grain processing production line.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The receiving hopper can directly hold the transported grain. When it is conveyed to the raw material silo by the first conveyor, the primary dust collector can remove some of the dust and light impurities contained in the grain during the conveying process, thus achieving a preliminary impurity removal effect.

[0015] 2. The compound gravity separator can clean grain materials according to their specific gravity, effectively removing chaff, stones, and other impurities, as well as shriveled, insect-infested, and moldy grain particles, achieving further impurity removal. The grading screen can further remove impurities through vibration and can also classify and screen grains according to different particle sizes, improving the uniformity of packaged grains. The second storage bin can collect grains that do not meet the particle size requirements and collect light impurities such as dust carried during transportation, which can be removed by a secondary dust collector, facilitating subsequent processing of this portion of grain material.

[0016] 3. Magnetic separators can remove magnetic particulate impurities from grain materials, while destoners can remove large particulate impurities such as sand and gravel mixed in with grain materials, further improving the cleanliness of grain materials.

[0017] 4. Microwave sterilizers can kill bacteria, viruses and other microorganisms through the thermal and biological effects of microwaves, improving the safety of packaged grains and extending their storage time. Attached Figure Description

DETAILED DESCRIPTION

[0021] The utility model will be described in further detail below in combination with the drawings and specific embodiments.

[0022] As Figure 1 shown, a grain processing production line comprises a primary impurity removal unit, a secondary impurity removal unit, a tertiary impurity removal unit, a sterilization unit and a finished product storage unit arranged in sequence;

[0023] The primary impurity removal unit comprises a receiving bin 1; the receiving bin 1 is externally connected with a raw material bin 2; the receiving bin 1 and the raw material bin 2 are connected with a first conveyor 3 for conveying materials; the receiving bin 1 and the raw material bin 2 are connected with a primary dust remover 4 for removing dust from the conveyed materials;

[0024] As Figures 1-2 shown, the secondary impurity removal unit comprises a compound specific gravity cleaner 6 connected with the raw material bin 2 through a second conveyor 5; the compound specific gravity cleaner 6 is connected with a first miscellaneous storage bin 8 at its impurity removal end through a third conveyor 7; the compound specific gravity cleaner 6 is connected with a grading screen 10 at its discharge end through a fourth conveyor 9; the grading screen 10 is connected with a second miscellaneous storage bin 12 at its impurity removal end through a fifth conveyor 11; the grading screen 10 and the second miscellaneous storage bin 12 are connected with a secondary dust remover 13 for removing dust from the conveyed materials;

[0025] The tertiary impurity removal unit comprises a magnetic separator 15 connected with the discharge end of the grading screen 10 through a sixth conveyor 14; the magnetic separator 15 is connected with a stone removing machine 17 at its discharge end through a seventh conveyor 16; the stone removing machine 17 is connected with a tertiary dust remover 18 for removing dust from the materials;

[0026] The sterilization unit comprises a microwave sterilization machine 19 connected with the discharge end of the stone removing machine 17;

[0027] The finished product storage unit comprises a finished product bin 21 connected with the discharge end of the microwave sterilization machine 19 through a finished product conveyor 20.

[0028] After the transported grain material is carried by the receiving hopper 1, it is conveyed to the raw material hopper 2 by the first conveyor 3. Through the adsorption and dust removal effect of the primary dust collector 4, some of the dust and light impurities contained in the grain can be removed, which performs the initial impurity removal of the grain and reduces the burden on the subsequent impurity removal process.

[0029] Next, the second conveyor 5 transports the grain material to the compound gravity separator 6, where it is cleaned according to its specific gravity. Grain material that meets the specific gravity requirement is transported to the grading screen 10 by the fourth conveyor 9, while grain material that does not meet the specific gravity requirement is transported to the first storage bin 8 by the third conveyor 7. This specific gravity separation allows the heavier grain material to be retained, while separating the grain material from impurities such as chaff, small stones, shriveled, insect-infested, and moldy grain particles that are not heavy enough, thus achieving further impurity removal and screening of the grain.

[0030] Of course, the materials screened by the compound gravity separator 6 usually have a relatively large specific gravity range, while the finished packaged grains have more detailed grading requirements according to different particle sizes. Therefore, the cleaned materials are then screened by the grading screen 10, which not only further removes impurities, but also allows the grains to be graded according to different particle sizes, meeting the different particle size requirements of different grades of packaged grains (of course, the dust and other impurities generated in this process can be sucked away by the secondary dust collector 13).

[0031] After the above-mentioned impurity removal process, the light and small-volume impurities in the material are basically cleaned up quite thoroughly. Then, the magnetic separator 15 removes magnetic particulate impurities, the destoner 17 removes large particulate impurities such as sand and gravel mixed in the grain material, and the three-stage dust collector 18 performs final dust collection. As a result, the impurities in the grain material can be removed quite thoroughly, meeting the requirements for grain purity during packaging.

[0032] After the impurities are removed, this technical solution also includes a sterilization unit, which enables the microwave sterilizer 19 to kill bacteria, viruses and other microorganisms through the thermal and biological effects of microwaves, thereby improving the safety of packaged grains and extending the storage time of the grains.

[0033] After the above processing is completed, the grain can be transported to the finished product warehouse 21 for subsequent packaging.

[0034] The dust collectors at each level in this technical solution can be cyclone dust collectors, air net dust collectors, etc., as needed. The conveyors at each level can be various conveying equipment such as screw conveyors, elevators, and conveyor belts. Similarly, the cleaning specifications of the compound gravity separator 6 and the screening specifications of the grading screen 10 can also be set as needed according to the requirements of different grain production.

[0035] like Figures 1-2As shown, the dust outlets of the primary dust collector 4, the secondary dust collector 13, and the tertiary dust collector 18 are all connected to the input end of the pulse pneumatic conveyor 22. The pulse pneumatic conveyor 22 effectively removes impurities absorbed by each stage of the dust collector. Its pulse conveying method gives it advantages such as high efficiency, stability, energy saving, reduced clogging and wear, and good environmental sealing.

[0036] like Figure 2 As shown, the third conveyor 7 is a Z-type elevator, which is conducive to timely conveying away the light materials that are separated from the compound gravity separator 6 in the upper layer, and does not occupy the length space, making full use of the height space and reducing the floor area.

[0037] like Figure 1 As shown, the discharge port of the finished product warehouse 21 is connected to a packaging scale 23. The packaging scale 23 facilitates the quantitative packaging of finished grain.

[0038] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model.
