Description

Technical Field

[0001] The invention relates to the technical field of rapeseed oil pressing, in particular to a rapeseed selection device and a use method thereof. Background Art

[0002] Rapeseed oil extraction is a common vegetable oil extraction process, mainly using rapeseed as raw material. Rapeseed is rich in oil, usually with an oil content of between 35% and 45%. The oil extraction process mainly includes cleaning, crushing, steaming, flaking, pressing and other steps. After filtering and sedimentation, the extracted oil can be treated to obtain golden and nutritious rapeseed oil.

[0003] Usually, rapeseed is carefully selected before oil extraction to remove impurities, shrunken seeds and moldy seeds. The rapeseed after selection is purer and the impurity content is greatly reduced, which not only helps to improve the efficiency of oil extraction, but also improves the quality and taste of the oil. The selection process can also remove diseased and insect-infested seeds and reduce the risk of loss and deterioration during storage.

[0004] Damaged rapeseed may lead to damage to the internal structure and rupture of oil cells, causing partial loss or oxidation of oil before processing, thereby reducing the final oil yield. Damaged rapeseed is more susceptible to microbial infection, causing oil rancidity or odor. In addition, damaged seeds may release more free fatty acids during processing, thereby increasing the acid value of the oil and reducing the quality of the oil.

[0015] A method for using a rapeseed selection device comprises the following steps:

[0016] S1. The selected rapeseed is input from the feed guide groove into the installation shell. After passing through the rear roller, the small rapeseed directly falls from the gap of the rear roller into the installation shell. The driven push plate and the screening fan work alternately to output the complete small rapeseed to the side collection box for collection. The incomplete small rapeseed directly falls into the receiving shell. When the rapeseed that has not fallen from the top passes through the inner support block, the screening fan is used to blow the empty shell into the receiving shell. The larger rapeseed continues to move forward to the front roller, the incomplete rapeseed is crushed, and the rapeseed shell and grease contaminated on the surface are scraped off by a scraper to select the complete large particles in the rapeseed;

[0017] S2. Start the driving motor to drive the active bevel gear to rotate. The top of the active bevel gear meshes with the shaft bevel gear and the roller bevel gear respectively. The shaft bevel gear and the roller bevel gear rotate in opposite directions. The roller bevel gear transmits the rotation to the roller active meshing gear and drives the roller active meshing gear on the other side to rotate. The two roller active meshing gears respectively drive the two front rollers to rotate, and when the surface of the front roller passes through incomplete rapeseed, the groove of the front roller will grab the surface of the rapeseed, pull it down and crush it, and the shaft bevel gear drives the active shaft to rotate, and the active shaft rotates in the opposite direction to the roller bevel gear on this side. The active shaft does not rotate with the middle The front roller, roller bevel gear, roller driven meshing gear and other components are connected, and are directly connected to the shaft meshing gear on the other side to drive it to rotate. The shaft meshing gear also drives the driven input bevel gear to rotate, and transmits the rotation to the roller driven meshing gear through the driven intermediate bevel gear and the driven output bevel gear. The rotation direction of the roller driven meshing gear is opposite to that of the driving shaft, and the rear roller is driven by the two roller driven meshing gears to rotate. Although the front roller and the rear roller on each side are separated in the middle, they still keep the same direction. The front rollers and the rear rollers on both sides cooperate with each other to crush the incomplete rapeseed and output it downward to the receiving shell;

[0018] S3. The driving shaft is not connected to the front roller, roller bevel gear, roller driven meshing gear and other parts in the middle, but is directly connected to the shaft meshing gear on the other side to drive it to rotate. There are also two shaft meshing gears, and the other shaft meshing gear drives the driven shaft to rotate. The driving shaft and the driven shaft drive the screening fan to rotate. The two screening fans are 180 degrees apart. When the screening fan on one side blows downward, the screening fan on the other side blows upward. The wind from the screening fan blowing downward is guided to the inner support blocks through the air guide groove, so that the oil passing through it The rapeseed and empty shells are subjected to the wind force from bottom to top, and enter the air duct composed of the top guide block and the side baffles. The screening fan blowing upward on the other side blows air in the air duct from both sides upward, driving the empty shells in the air duct into the receiving shell, and the screening fans are all opposite to the rotation direction of the front roller and the rear roller on this side, so that the incomplete shells are crushed from the front roller and the rear roller and output downward to the receiving shell, while the empty shells are blown by the screening fan and output upward to different compartments of the receiving shell, which has the effect of separating the incomplete rapeseed and the empty shells of rapeseed;

[0019] S4. The driven shaft rotates and drives the cam column on the surface to rotate. The cam column drives the reciprocating arm to realize reciprocating movement and drives the driven push plate to reciprocate. The driven push plates on both sides are connected by a toggle arm. When the driven push plate on one side moves, the driven push plate on the other side will be toggled by the toggle arm, so that the two driven push plates are always in opposite positions, and each driven push plate pulls the blocking plate on the other side through the traction rope. When the driven push plate is away from the blocking plate, the blocking plate on the same side will be lowered. In this way, when the incomplete small particles and the complete small particles are ejected from the gap between the rear rollers, After falling, it will fall into the inner guide plate and continue to fall, rolling down to the two driven push plates in the fixed inclined slot. The screening fans on both sides will rotate to output wind force downward in turn, and blow the complete small-particle rapeseed on the driven push plate and roll it to the side collection box on the other side. The rapeseed with surface defects cannot be blown away, and waits to be pushed into the receiving shell by the fixed inclined slot after the driven push plate is folded up. At this time, the blocking plate on this side is lowered, and no new rapeseed will enter the driven push plate, thereby achieving the effect of alternating screening of small-particle rapeseed according to the rotation state of the screening fan.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] In the present invention, through the setting of the driving mechanism, the power of a single motor can be distributed to multiple working parts such as front rollers, rear rollers, screening fans, etc., to ensure that the components work together, control the crushing and air separation of the crushing and air separation mechanism, so that the crushed rapeseed and the empty shells after air separation are cached in different areas for distinction. After multi-stage screening, it is ensured that the rapeseed finally collected has high purity and few impurities.

[0022] In the present invention, through the cooperation of the driving mechanism and the rolling and air separation mechanism, through the dual effects of rolling and air separation, incomplete rapeseed and empty shells can be effectively separated, and the purity of the selection can be improved. The combination of mechanical rolling and wind screening greatly improves the screening efficiency and reduces the labor intensity of manual screening.

[0023] In the present invention, small-particle rapeseed is further screened through various combinations of a rolling and air-selecting mechanism and a secondary screening mechanism. Complete rapeseed, incomplete rapeseed and empty shells can be efficiently separated through the multiple effects of mechanical rolling, wind screening and secondary screening.
