Drying temperature and water content–strength correlations

High Temperature Walnut Drying

On farm walnut drying is often a major bottle neck during the start of walnut harvest. The recommended maximum drying air temperature for English walnuts is 110 of. This limit is based on tests by university personnel during the introduction of heated air drying (Batchelor, 1924) which demonstrated that long term exposure to temperatures higher that 110°F caused walnuts to turn rancid. This pro...

Lyophilizing Foot-and Mouth Disease Virus at Low Drying Temperature

Freeze-drying above room temperature.

This study investigates the use of solid, organic compounds to lyophilize drugs without conventional freeze-drying equipment. The aim of the investigation is to find a pharmaceutically acceptable solvent or solvent combination that is appropriate for freeze-drying on the basis of its ability to (1) solubilize hydrophobic drugs, (2) provide a stable environment for water-sensitive compounds, (3)...

Influence of drying temperature, water content, and heating rate on gelatinization of corn starches.

The gelatinization properties of starch extracted from corn and waxy corn dried at different temperatures were determined at various water contents and heating rates by differential scanning calorimetry. All gelatinization transition temperatures increased with drying temperature and heating rate. Onset and peak temperatures remained relatively constant, whereas end temperature decreased in the...

Effects of drying temperature on barrier and mechanical properties of cold-water fish gelatin films

Fish gelatin films made from Alaska pollock (Theragra chalcogramma) and Alaska pink salmon (Oncorhynchus gorbuscha) were dried at 4 C, 23 C, 40 C, and 60 C. The tensile, thermal, thermal stability, water sorption, and water vapor permeability properties were examined for cold-cast gelatin films (dried below gelation temperature at 4 C) and hot-cast gelatin films (dried above gelation temperatur...
