重力式精選機(jī) Gravity separator

重力式精選機(jī)是用在風(fēng)篩式精選機(jī)力所不能及的領(lǐng)域，這不是說重力式精選機(jī)可以替代風(fēng)篩式精選機(jī)，重力式精選機(jī)是以顆粒間重力差異（千粒重）為基礎(chǔ)、是一種更加精確分離雜質(zhì)的另外一道工序。

經(jīng)過風(fēng)篩式精選機(jī)把大雜、小雜、灰塵等雜質(zhì)剔除，顆粒大小相同而重力（千粒重）發(fā)生差異，就由重力式精選機(jī)通過重力差異的特性來精選，把同等大小的石塊、土塊、破碎粒、蟲蛀粒、病變粒、發(fā)霉變質(zhì)的、秕粒、未成熟等物料分離出來。例如從可可坯芽中分離破損的可可豆；從杏仁中去殼；從生咖啡豆中去除帶殼和開裂的咖啡豆；將茶葉分級(jí)；從黑麥中去除患有麥角癥的籽粒；榛子、花生等干果中去除它們的殼、枝和其他雜物。

技術(shù)升級(jí)：下風(fēng)機(jī)由多臺(tái)獨(dú)立運(yùn)轉(zhuǎn)的風(fēng)機(jī)組成，而不是由一根主軸串連多臺(tái)風(fēng)機(jī)，因此維修保養(yǎng)更簡(jiǎn)單、更便捷。

選種臺(tái)面蜂窩狀勻風(fēng)裝置，出風(fēng)均勻、一致，無局部噴泉狀，精選效果好，質(zhì)量高。（當(dāng)種子均勻鋪滿在選種臺(tái)面達(dá)3-5公分厚度時(shí)，被空氣室正壓氣流整體吹起進(jìn)行分層，輕的浮在上，重的沉在下。所以輕的種子浮在上面因接觸不到振動(dòng)臺(tái)面而失去向上的爬升力，只會(huì)往最低的排雜口流出；相反，較重的種子沉在下面，能接觸到振動(dòng)臺(tái)面而產(chǎn)生向上的爬升力。）

智能自動(dòng)化功能：

1、所有動(dòng)力全部采用伺服、變頻電機(jī)，大量運(yùn)用伺服、變頻、PLC、上位機(jī)等智能自動(dòng)化技術(shù)，再配上各種傳感器把檢測(cè)數(shù)據(jù)上傳給觸摸屏，使設(shè)備的轉(zhuǎn)速、扭矩、溫度、振動(dòng)頻率、空氣流量、空氣壓力、風(fēng)門角度，縱向、橫向角度等參數(shù)直觀的顯示在觸摸屏，運(yùn)行情況一目了然。

2、當(dāng)設(shè)備調(diào)整到最佳狀態(tài)時(shí)，相關(guān)數(shù)據(jù)一鍵保存，下次加工相同種子只需一鍵恢復(fù)，對(duì)操作人員的專業(yè)技術(shù)要求低，無需憑個(gè)人經(jīng)驗(yàn)來使用設(shè)備。

3、把手動(dòng)操作步驟換成伺服電機(jī)來執(zhí)行，操作人員不用跑前跑后，只需在觸摸屏上輸入相關(guān)參數(shù)來命令伺服電機(jī)，把復(fù)雜的事情變?yōu)楹?jiǎn)單。

4、排雜出料口、成品出料口安裝高清攝像頭，方便管理人員在顯示器上查看調(diào)整設(shè)備后的相關(guān)情況。

5、智能自動(dòng)化設(shè)備平均節(jié)能30%，降低使用成本。

6、所有的運(yùn)行狀態(tài)由觸摸屏全中文顯示，具有故障提示、自診斷功能。

7、軟件具有遠(yuǎn)程升級(jí)、查看、診斷功能，方便廠家遠(yuǎn)程服務(wù)，方便用戶管理人員。

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.
