重力式精选机是用在风筛式精选机力所不能及的领域，这不是说重力式精选机可以替代风筛式精选机，重力式精选机是以颗粒间重力差异（千粒重）为基础、是一种更加精确分离杂质的另外一道工序。
经过风筛式精选机把大杂、小杂、灰尘等杂质剔除，颗粒大小相同而重力（千粒重）发生差异，就由重力式精选机通过重力差异的特性来精选，把同等大小的石块、土块、破碎粒、虫蛀粒、病变粒、发霉变质的、秕粒、未成熟等物料分离出来。例如从可可坯芽中分离破损的可可豆；从杏仁中去壳；从生咖啡豆中去除带壳和开裂的咖啡豆；将茶叶分级；从黑麦中去除患有麦角症的籽粒；榛子、花生等干果中去除它们的壳、枝和其他杂物。
技术升级：下风机由多立运转的风机组成，而不是由一根主轴串连多台风机，因此维修保养更简单、更便捷。
选种台面蜂窝状匀风装置，出风均匀、一致，无局部喷泉状，精选效果好，质量高。（当种子均匀铺满在选种台面达3-5公分厚度时，被空气室正压气流整体吹起进行分层，轻的浮在上，重的沉在下。所以轻的种子浮在上面因接触不到振动台面而失去向上的爬升力，只会往的排杂口流出；相反，较重的种子沉在下面，能接触到振动台面而产生向上的爬升力。）
智能自动化功能：
1、所有动力全部采用伺服、变频电机，大量运用伺服、变频、PLC、上位机等智能自动化技术，再配上各种传感器把检测数据上传给触摸屏，使设备的转速、扭矩、温度、振动频率、空气流量、空气压力、风门角度，纵向、横向角度等参数直观的显示在触摸屏，运行情况一目了然。
2、当设备调整到状态时，相关数据一键保存，下次加工相同种子只需一键恢复，对操作人员的专业技术要求低，无需凭个人经验来使用设备。
3、把手动操作步骤换成伺服电机来执行，操作人员不用跑前跑后，只需在触摸屏上输入相关参数来命令伺服电机，把复杂的事情变为简单。
4、排杂出料口、成品出料口安装高清摄像头，方便管理人员在显示器上查看调整设备后的相关情况。
5、智能自动化设备平均节能30%，降低使用成本。
6、所有的运行状态由触摸屏全中文显示，具有故障提示、自诊断功能。
7、软件具有远程升级、查看、诊断功能，方便厂家远程服务，方便用户管理人员。
注：以上智能配置可选，我们按需报价。

Gravity separator is used in the field that the force of air screen separator cannot reach. This is not to say that gravity separator can replace air screen separator. Gravity separator is another process based on the gravity difference between particles (1000 particle weight), which is a more accurate separation of impurities.
Through the air screen cleaning machine, the impurities such as big impurity, small impurity and dust are removed, and the particle size is the same, but the gravity (1000 grain weight) is different. The gravity cleaning machine selects the same size of stones, soil blocks, broken particles, moth eaten particles, pathological particles, moldy and deteriorated, chaff particles, immature and other materials through the characteristics of gravity difference. For example, the broken cocoa bean is separated from the bud of cocoa; the shell is removed from the almond; the coffee bean with shell and crack is removed from the raw coffee bean; the tea is graded; the seeds with ergot disease are removed from the rye; the shells, branches and other sundries of hazelnut, peanut and other dried fruits are removed.
Technical upgrading: the lower fan is composed of several independent fans rather than one main shaft connected with multiple fans in series, so the maintenance is simpler and more convenient.
The honeycomb air homogenizing device on the seed selection table has uniform and uniform air output, no local fountain, good selection effect and high quality. (when the seeds are evenly spread on the seed selection table with a thickness of 3-5cm, they will be blown by the positive pressure air flow in the air chamber as a whole for layering, floating on the top with light weight and sinking on the bottom with heavy weight. Therefore, the light seeds floating on the top will lose the upward climbing force due to not contacting the vibration table, and will only flow out to the lowest trash discharge port; on the contrary, the heavier seeds sinking on the bottom can contact the vibration table and produce the upward climbing force.)
Intelligent automation function:
1. Servo and variable frequency motors are used in all power systems. Servo, variable frequency, PLC, upper computer and other intelligent automation technologies are widely used. In addition, various sensors are equipped to upload the test data to the touch screen, so that the parameters such as rotating speed, torque, temperature, vibration frequency, air flow, air pressure, air door angle, longitudinal and transverse angles of the equipment can be displayed on the touch screen intuitively The situation is clear at a glance.
2. When the equipment is adjusted to the best state, the relevant data can be saved with one key. The next processing of the same seed only needs one key to restore. The professional and technical requirements for the operators are low, and the equipment does not need to be used by personal experience.
3. The manual operation steps are replaced by servo motor to execute. The operator does not need to run before and after, but only needs to input relevant parameters on the touch screen to commａnd the servo motor, which makes the complex things simple.
4. HD cameras are installed at the discharge outlet and finished product outlet to facilitate the management personnel to check the relevant conditions after adjusting the equipment on the display.
5. The average energy saving of intelligent automation equipment is 30%, and the use cost is reduced.
6. All operation states are displayed in Chinese and English on the touch screen, with fault prompt and self diagnosis functions.
7. The software has the function of remote upgrade, check and diagnosis, which is convenient for the remote service of the manufacturer and the user management personnel.
Note: the above intelligent configuration is optional, and we offer on demand.
