Temperature and pretreatment effects on the drying of

01/12/2015The drying experiments of the non-pretreated and pretreated (sliced and crushed) Hass avocado seeds were performed in a heating furnace where the pretreatment process was found to accelerate the drying process The obtained results suggested that increase in the operating air temperature stimulated the rate of moisture evaporation but resulted in the charring of the seed surface The drying

Effects of different pretreatments on drying

EFFECTS OF DIFFERENT PRETREATMENTS ON DRYING CHARACTERISTICS OF BANANA SLICES Abano E E and Sam-Amoah L K Department of Agricultural Engineering University of Cape Coast Ghana E-mail: ekowabanoyahoo ABSTRACT The effects of different pretreatments and temperature on the drying characteristics of ripe Gros Michel banana slices were investigated 5

How Temperature Affect Grinding Efficiency

The effects of temperature on autogenous grinding can be immediately divided into rheological effects and mechanical effects The rheological effects are a result of the substantial increase in the viscosity of water as the freezing point is approached The change in apparent slurry viscosity which results from changing temperature is shown in Figure 1 As can be seen the effect at high

Statistical Analysis of the Effects of Drying Temperature

Statistical Analysis of the Effects of Drying Temperature and Pretreatment on the Proximate Composition of Dried Matured Green Plantain (Musa Paradisiaca) Drying has been identified as the efficient means of ensuring continuous food supply to the growing population of any country and to enable the farmers produce more high quality marketable products In this study the effects of drying

An Introduction to the Drying Food Preservation Method

Drying is the simple process of dehydrating foods until there is not enough moisture to support microbial activity Drying removes the water needed by bacteria yeasts and molds need to grow If adequately dried and properly stored dehydrated foods are shelf stable (safe for storage at room temperature) The drying food preservation method is easy to do very safe and can be used for most
