利用啤酒糟生产营养食醋

将２００ｋｇ啤酒糟、２５ｋｇ玉米粉、３６ｋｇ麸皮混匀 ,堆积２～１２ｈ（冬长夏短） ,蒸料１．５～２ｈ,再焖３０ｍｉｎ,４０℃时接入Ａｓ．３．３５０黑曲霉和Ａｓ．３．５９１米曲霉 ,接种量分别为０．３５%～０．１%和３０～３５℃通风培养２６～２８ｈ。再加入酒母和水 ,使发酵醅含水６２%～６５% ,品温２２～２４℃入缸压实、封严 ,当品温过３５℃时应倒缸 ,发酵７～８天。再与２６ｋｇ麸皮、３２ｋｇ稻糠、８０ｋｇ水混合 ,入浅缸敞口８～１０ｈ ,接上批发酵３～４天的热醋醅１% ,每天倒缸 ,发酵７～８天 ,向醋醅内加盐、拌匀 ,堆…     

非理想多组分混合物中质量传递过程基于Maxwell-Stefan扩散理论的建模及数值分析(英文)

The Intalox metal tower packing was used to simulate an industrial relevant extractive distillation column for purifying azeotropic multicomponent mixture.In order to explain the inconsistencies in the modeling of transfer process in nonideal multicomponent distillation column,a method was developed with equilibrium stage models(EQ)and non-equilibrium model(NEQ)incorporated with Maxwell-Stefan diffusion equations in the framework of AspenONE  simulator.Dortmund Modified UNIFAC(UNIFAC-DMD)thermodynamic model was employed to estimate activity coefficients.In addition,to understand the reason for the diffusion against driving force and the different results by EQ and NEQ models,explicit investigations were made on diffusion coefficients, component Murphree efficiency and mass transfer coefficients.The results provide valuable information for basic design and applications associated with extractive distillation.     

心电信号实时采集系统

<正> 电生理信号的现场采集多采用磁带记录模拟方式,然后通过A/D转换送回微机分析处理。这样导致信号失真大,传输速度慢,再者由于存在大量机械部件使得系统可靠性下降。本系统采用大容量SRAM存储数据,使用串行通讯方式与微机进行数据交换,提高了传输速度及可靠性。由于采取了数字滤波,数据压缩编码等技术,大大改善了波形记录质量,延长了记录时间。其主要功能和特点介绍如下:     

关于白酒酒库设计中的几点体会

新蒸馏出的白酒,气味不正,有所谓的“新酒臭”,口味上有粗糙、辛辣而刺激性大等不悦感。因此,新酒要经过适当的贮存期,使酒内各种成分之间变得更加协调,香气增加,酒味柔和。白酒就是在酒库中实现这一过程的,现就白酒酒库的设计谈几点个人体会,仅供同行参考指正。...
