中文摘要:
      洞道式水产品烘干房的供热,系由水分蒸发热Qv物料及运载工具升温吸热Q排潮失热Q0及烘道各项热损失Ql等四项热量所组成。而混合风的温度t湿含量xo则由相应方程式来计算。本文并讨论了以下诸问题: 1.有关干燥过程供热Qr的计算方法, 2.以干基为准和以湿基为准问题的研究, 3.关于混合风状态的确定, 4.干燥介质参数的选定。
英文摘要:
      The heat supply for the circulating air in tunnel driers of partial recirculatingwaste moist gas comprises of four heat comsumptions. (i. e. the sensible heat of exhaustgas, heat of evaporation, heat of elevation of materials and transport equipments, andthe heat loss during drying process). The temperature (tc) and humidity (x0) of mixinggas are calculated by means of corresponding equations with clear conception. The following suggestions are consulted with the aid of mathematical treatment: 1. The total heat supply calculated with other different methods can also be sum-marized into four similar terms. 2. The sensible heat and heat of evaporization either with dry or wet base are pro-ved to be perfectly identical with the real case. 3. The values obtained for the properties of air mixture from the tunnel drier bothby I-X chart and by calculation are in close agreements. 4. The choice of parameters of drying medium is considerably important in dryingprocesses design. Acompanying the velocity of drying medium, the teperature (t2) andhumidity (x2) of the exhaust moist gas are suggested as basic parameters.
