油脂浸出设备；概述油脂浸出设备中分子扩散对流的基本原理
　　Basic principles of molecular diffusion convection of oil leaching equipment
　　萃取分为固一液萃取和液—液萃取。例如，用水萃取甜菜中的糖分，用开水泡茶，用轻汽油辈取料胚中的油脂等等，都归于固—液萃取范畴。习惯上我们把固—液萃取称为浸出。
　　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.
　　当浸出进程中溶剂和料胚处于相对运动状何况呈湍流时，其传质办法又存在对流涣散。
　　When in the solvent and the leaching process of material relative motion and shape is turbulent, the mass transfer and convection and lax measures.
　　分子涣散就是以分子热运动的办法进行的物质转移。
　　Molecular slack is in molecular thermal motion of the material transfer way.
　　当料胚与溶剂触摸后，油分子以无次序的热运动办法从料胚中渗透出来并涣散到溶剂中去，相应地，溶剂分子也不断地渗透到油料中去与油分子相溶合。
　　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.
　　这么，就在料胚内部和溶剂里都形成了溶液 (即混合油)。
　　In this way, the solution is formed in the inner and the solvent of the material.
　　对流涣散是指物质以相对运动的办法进行转移，是溶液以较小的体积在湍流的情况下以的速度从一处移向另一处。
　　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.
　　在活动中被溶解的物质跟着转移，终使遍地的浓度趋于一起。
　　In the activities of the dissolved substance followed by transfer, and eventually make the concentration of over and over.
　　对流涣散的规矩标明，涣散的物质量与涣散面积、涣散物质的浓度差和涣散时间成正比。
　　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，涣散面积、涣散物质的浓度差以及涣散时间都会影响对流涣散进程，但要使传质进程以对流涣散这种办法进行，关键是流体有呈湍流情况。
　　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.
