摘要:

An analysis technique is described which uses the nonlinear curve fitting capabilities of the Statistical Analysis System (SAS) to analyze batch drying data. The technique does not require any apriori assumptions about whether a constant rate period exists. Rather, the only assumptions necessary are the possible forms of the equations which can be used to describe the drying phenomenon. The program will then determine, based upon statistical techniques, where each equation should be used during the drying process in order to best describe the overall drying process. Two examples are given; the first analyzes the drying of. sand, a material having a constant rate period; the second analyzes the data describing the drying of French fried potato pieces.

摘要:

A study was made of a centrifugal pressure nozzle with large orifice diameter (8-10 nun) for producing dry milk in capacity of 2-3 tons per hour to develop some performance data on spray distribution, drop size distribution, and capacity with changing spray drying conditions such as nozzle pressure, orifice diameter and spray angle.

摘要:

The basic analitical method for so-called expression operation, the separation of liquid from solid-liquid systems by compression, are presented in view of the flow through compressible porous media. It has become evident that the expression mechanism consists of two flow phenomena. These types of phenomena can be analyzed by consideration of the flow mechanism through compressible porous beds, first by the filtration theory and second by the so-called consolidation theory. A simplified equation is also presented. It is shown that the simplified equation is well applicable to industrial expression problems even when the creep effects of matarials to be expressed are appreciable

摘要:

A model for contact drying of wood veneer is presented and compared with experimental results. The model is and-dimensional and assumes that convective transport of liquid and vapor is dominant for the drying conditions examined. Model results are in good agreement with the experimental data.

摘要:

A natural solar drying system has been tested with wheat. Simple solar collectors give the small temperature rise needed for low temperature drying. The system, with a capacity of 35 tomes, is placed in a region of humid hot-temperate climate. It has been designed to dry all the locally produced grain (wheat, corn, soybean, sunflower, sorghum, etc.), without a supplemental heat source.

摘要:

A kinetic study of ice sublimation in a fluidized-bed dryer operating under atmospheric conditions is described. The influence of some experimental conditions such as temperature, air flow rate, on sublimation time was investigated. Mathematical expressions were formulated to account for variations in mass and dimensions of ice samples during sublimation. Ice temperature and temperature of fluidized-bed in which the ice is submerged are correlated; prediction bf ice temperature is demonstrated graphically from known fluidized-bed temperatures. The kinetics of ice sublimation in the atmospheric dryer is shorn to be regulated by the expression
