摘要： Provided is a method for preparing citric acid comprising the following steps: (1) contacting and reacting the fermentation liquid of citric acid with calcium carbonate and/or calcium hydroxide under the condition that the citric acid in the fermentation liquid can be converted into calcium hydrogen citrate, and subjecting the obtained slurry to a solid-liquid separation to obtain solid calcium hydrogen citrate and a first liquid phase; (2) subjecting the solid calcium hydrogen citrate obtained in step (1) to acidolysis to obtain citric acid; (3) contacting and reacting the first liquid phase obtained in step (1) with calcium carbonate and/or calcium hydroxide under the condition that the calcium hydrogen citrate dissolved in the first liquid phase can be converted into calcium citrate, subjecting the obtained slurry to a solid-liquid separation to obtain solid calcium citrate, and recycling the solid calcium citrate to step (1).
摘要翻译：提供一种柠檬酸的制备方法，包括以下步骤：（1）使柠檬酸的发酵液与碳酸钙和/或氢氧化钙接触并使之发生反应，发酵液中的柠檬酸可以转化为氢化钙柠檬酸盐，并将得到的浆料进行固液分离，得到固体柠檬酸钙和第一液相; （2）使步骤（1）中得到的固体柠檬酸氢钙经酸解，得到柠檬酸; （3）使在步骤（1）中获得的第一液相与碳酸钙和/或氢氧化钙接触并使其溶解在第一液相中的柠檬酸氢钙可以转化成柠檬酸钙，固液分离以获得固体柠檬酸钙，并将固体柠檬酸钙再循环到步骤（1）。

摘要： Disclosed herein is a skin-removing method for root and tuber crops by using a skin-removing device which comprises a pedestal; a rotary drum rotatably fitted on the pedestal and having an inlet and a outlet; a helical screw feeder provided in the rotary drum and fixedly connected with the inner wall of the rotary drum; and a driving unit for driving the rotary drum and the helical screw feeder to rotate together, wherein the method includes feeding raw material of root and tuber crops into the rotary drum via the inlet, allowing the driving unit to drive the rotary drum and the helical screw feeder to rotate together. In the method according to the present invention, raw material of root and tuber crops is fed into the rotary drum via the inlet, and the driving unit drives the rotary drum and the helical screw feeder to rotate together. Under push action of the helical screw feeder, the raw material is continuously moved forward, and at the same time the raw material rotates along with the rotary drum and the helical screw feeder. During rotation, friction is generated not only among the raw material, but also between the raw material and the rotary drum wall and the helical screw feeder, so as to remove the skin of the raw material without damaging the flesh of root and tuber crops, such that the loss of raw material is low.
摘要翻译：本文公开了通过使用包括基座的皮肤去除装置的根和块茎作物的去皮方法; 可旋转地安装在基座上并具有入口和出口的旋转鼓; 螺旋螺旋进料器设置在旋转滚筒中并与旋转滚筒的内壁固定连接; 以及用于驱动旋转滚筒和螺旋螺旋进料器一起旋转的驱动单元，其中所述方法包括通过入口将根块和块茎作物的原料进料到旋转滚筒中，允许驱动单元驱动旋转滚筒和螺旋螺旋进料器一起旋转。在根据本发明的方法中，根和块茎作物的原料经由入口进料到旋转滚筒中，驱动单元驱动旋转滚筒和螺旋螺旋进料器一起旋转。在螺旋螺旋进料器的推动作用下，原料连续向前移动，同时原料与旋转滚筒和螺旋螺旋进料器一起旋转。在旋转过程中，不仅在原材料之间产生摩擦，而且在原料与旋转鼓壁和螺旋螺旋进料器之间产生摩擦，从而除去原料的皮肤而不会损坏根和块茎作物的肉，使原料的损失低。
