油脂浸出設(shè)備；概述油脂浸出設(shè)備中分子擴(kuò)散對(duì)流的基本原理
　　Basic principles of molecular diffusion convection of oil leaching equipment
　　萃取分為固一液萃取和液—液萃取。例如，用水萃取甜菜中的糖分，用開(kāi)水泡茶，用輕汽油輩取料胚中的油脂等等，都?xì)w于固—液萃取范疇。習(xí)慣上我們把固—液萃取稱(chēng)為浸出。
　　The extraction is divided into solid liquid extraction and liquid liquid extraction. For example, in the water extraction of sugar beet sugar, tea with boiling water, light gasoline generation reclaimer germ oil and so on, are attributed to the solid liquid extraction areas. We used to put the solid - liquid extraction as the leaching.
　　當(dāng)浸出進(jìn)程中溶劑和料胚處于相對(duì)運(yùn)動(dòng)狀何況呈湍流時(shí)，其傳質(zhì)辦法又存在對(duì)流渙散。
　　When in the solvent and the leaching process of material relative motion and shape is turbulent, the mass transfer and convection and lax measures.
　　分子渙散就是以分子熱運(yùn)動(dòng)的辦法進(jìn)行的物質(zhì)轉(zhuǎn)移。
　　Molecular slack is in molecular thermal motion of the material transfer way.
　　當(dāng)料胚與溶劑觸摸后，油分子以無(wú)次序的熱運(yùn)動(dòng)辦法從料胚中滲透出來(lái)并渙散到溶劑中去，相應(yīng)地，溶劑分子也不斷地滲透到油料中去與油分子相溶合。
　　When touching a blank and solvent, oil molecules to order free thermal motion way from blank seeps out of the and lax to the solvent, accordingly, the solvent molecules also continue to penetrate into the oil to oil molecules and mix.
　　這么，就在料胚內(nèi)部和溶劑里都形成了溶液 (即混合油)。
　　In this way, the solution is formed in the inner and the solvent of the material.
　　對(duì)流渙散是指物質(zhì)以相對(duì)運(yùn)動(dòng)的辦法進(jìn)行轉(zhuǎn)移，是溶液以較小的體積在湍流的情況下以的速度從一處移向另一處。
　　Convection and lax is a substance to relative motion transfer, is the solution to a smaller volume in the turbulent flow to a certain speed from one place to another.
　　在活動(dòng)中被溶解的物質(zhì)跟著轉(zhuǎn)移，終使遍地的濃度趨于一起。
　　In the activities of the dissolved substance followed by transfer, and eventually make the concentration of over and over.
　　對(duì)流渙散的規(guī)矩標(biāo)明，渙散的物質(zhì)量與渙散面積、渙散物質(zhì)的濃度差和渙散時(shí)間成正比。
　　Convection and lax rules indicate, the quality and concentration of lax lax, LAX area material and slack time is proportional to the difference.
　　由此可知，渙散面積、渙散物質(zhì)的濃度差以及渙散時(shí)間都會(huì)影響對(duì)流渙散進(jìn)程，但要使傳質(zhì)進(jìn)程以對(duì)流渙散這種辦法進(jìn)行，關(guān)鍵是流體有呈湍流情況。
　　Thus it may be known, LAX area, lax material concentration difference and slack time will influence the process of convection and lax, but the mass transfer process by convection and lax this way of, the key is fluid is necessary in a turbulent flow.
