Detailed Description

The invention is further described below with reference to the figures and examples.

Examples

An oil material screening and processing device is shown in figures 1-7 and comprises support legs 1, a fan 2, a seed separating and peeling device 3, a control screen 4, a quality identification device 5, a seed collecting device 6, a poor product collecting box 7 and a foot pad 8; a fan 2 is arranged in the left middle of the support leg 1; the top ends of the support legs 1 are welded with the seed stripping device 3; the left top of the seed separating and peeling device 3 is connected with the control screen 4 through a bolt; the right side of the seed stripping device 3 is in transmission connection with the quality identification device 5; the middle top of the quality identification device 5 is in transmission connection with the seed collection device 6; a inferior product collecting box 7 is arranged below the middle part of the bottom of the seed collecting device 6; the right bottom of the seed collecting device 6 is provided with a foot pad 8.

The working principle is as follows: during the use, install the oil screening hemp processing apparatus in the place that needs used earlier, external power supply, the whole trunk hemp that the length that will select is suitable is invertd and is put into seed collection device 6 and fixed, then through control screen 4 starting drive, get rid of the pendulum through seed collection device 6 repeatedly, pat the striking at the in-process of getting rid of the pendulum to the top of hemp plant, all get rid of the ripe hemp seed in top and drag and fall, this in-process because the plant itself has the leaf as the buffering, the in-process of beating the seed is negligible to the injury of seed itself, efficiency is higher than artifical hand shell far away. The hemp seeds dropped from the top of the plant are guided by the baffle plates to fall into the quality discriminating device 5, and then the quality discriminating device 5 screens and removes small particles and unsaturated seeds to enter the poor product collecting box 7 for other use, so as to leave the saturated seeds. And then, taking the plump seeds from the quality identification device 5, wherein the outer parts of the seeds are wrapped by the outer skins and cannot be used for oil extraction, the collected plump seeds are put into the seed peeling device 3, the hemp seeds are heated by the built-in heating device, the moisture of the outer skins is rapidly lost, the outer skins are dried and fragile, then the seeds are rolled, the outer skins are crushed, the seeds in the seeds are exposed, and the influence of the temperature is small because of the high oil content of the seeds. The general method is that seeds with hulls are directly knocked vigorously to break the outer skins, although the seeds can be shelled and obtained, the inner surfaces of the outer skins and the surfaces of the seeds are in a sticky state during knocking, the seeds are deformed due to the vibration of the strong knocking, the broken outer skins can be embedded into the seeds, the surfaces of the seeds are not cleaned subsequently, and finally, oil in the seeds is lost, so that the oil expression is reduced, the waste is serious, a large amount of outer skin impurities are contained in the squeezed oil, the extra filtering operation is needed, and the processing process is more complicated; however, the mode of hot dehydration and crushing is adopted, because the dehydrated outer skin becomes dry and crisp, the outer skin can be crushed only by applying a minimum pressure to the seeds, and because the inner surface of the outer skin is separated from the surface of the seeds after the hot dehydration, the shelling is easier, the outer skin can not be embedded into the surface of the seeds, the impurities in the oil are less during the subsequent oil pressing, and the treatment is easier. The device is simple to use, the seeds are completely separated from the hemp plants under the action of blade buffering by swinging the plants and beating the growing positions of the seeds at the tops of the plants by using the seed separating and peeling device 3, the traditional manual peeling is replaced, the efficiency is higher, the recovery is more thorough, and the waste is less; the seed is peeled off device 3 through the seed and is heated earlier and make the dehydration of seed crust become futilely, crisp, and internal surface and seed surface separate each other simultaneously, so long as exert minimum pressure to the seed this moment and can directly pulverize the crust, can not cause serious injury to the seed in addition, protect the seed when reaching the purpose, improve final oil output, be worth using widely.
