摘要/Abstract

摘要： 设计制作了直立分室式流体连续通电加热系统，利用该系统对自来水(流量为(40±0.3)kg/h,(50±0.3)kg/h)和豆浆(固形物含量为6.01%,流量为(50±0.5)kg/h,(75±0.5)kg/h)进行了试验研究.试验结果显示每一加热室轴线中点处自来水和豆浆的温度与加热装置的长度成线性关系；整个通电加热装置内自来水和豆浆的温度自下而上按加热室分段均匀上升；第Ⅵ加热室内自来水和豆浆在中心平面内中心位置上的温度均大于靠近壁管的温度，在中轴线上不同平面内的温度增幅均较明显，能分层均匀上升.

Abstract: A continuous ohmic heating system with vertical compartments for liquor was designed. The tap water ((40±0.3) kg/h and (50±0.3) kg/h the mass flow rate) and the soybean milk (6.01% the solids content, (75±0.5) kg/h and (50±0.5) kg/h the mass flow rate) were treated with this system. The results show that the temperature of tap water and soybean mitk at the center point of each compartment's axis is linear with the length of the ohmic heating compartment. The temperatures of tap water and soybean milk rise evenly within each ohmic heating compartment from the bottom to the top. Inside the sixth ohmic heating compartment, the temperatures of tap water and soybean milk at the center point of the central plane are all higher than those near the pipe wall. The temperatures of tap water and soybean milk in different planes along the axis increase obviously and evenly.
