Hot-Air Treatment Device for Quarantine Research

Mathematical models based on heat transfer and coupled heat and mass transfers for rapid high temperature treatment in fluidized bed: Application for grain heat disinfestation

“…However, because of increasing consumer dissatisfaction with the presence of residues in cereals and other foodstuffs, more interest has recently been directed towards thermal treatment methods. Heat disinfestation, conventional heating comprised of convective heat transfer from a medium, usually heated air or hot water, to the product surface, after which the heat flows inward from the surface to the center of the product, as well as combinations of convective and radiation heat transfer, have been extensively studied for controlling insect pests in fruits [1][2][3][4][5][6][7][8][9][10][11] and grains [12][13][14][15][16][17][18][19][20][21][22]. Technologies for the rapid high temperature disinfestation of grain have been available for many years; among these technologies is the fluidized bed which has interested many researchers [12][13][14][15][16][17] because of its great advantages in rapidly promoting heat transfer and thorough mixing, leading to uniform product properties.…”

Understanding Perceptions Regarding Availability, Quality, Status and Methods Used in Storing Fruits and Vegetables in Pakistan^|^prime;s Dera Ismail Khan District

“…Whereas, in recent years, the heat treatment techniques (placing under hot water and hot air for a specific time before storage) have successfully been applied to a number of fruit and vegetable storage processes including apple 25,31 , banana 3 , cherry 26 , mangoes 9,16,28 , peaches 10 , orange 17,19,20 , tomato 5,19,20,23 , potato 6 , and grapefruit 30 . This is probably due to the production of heat shock proteins in the living tissues, which led to a reduction in water loss during storage 4,11,27 .…”

Improving heating uniformity of fresh fruit in radio frequency treatments for pest control

“…Several alternative methods have been investigated, including ionizing radiation (Burditt, 1982), cold storage (Schiffman-Nadel et al, 1972, 1975, conventional hot air and water heating (Sharp et al, 1991;Shellie et al, 1992;Shellie and Mangan, 1993, 1995, 1998, and radio frequency (RF) treatments (Hallman and Sharp, 1994;Tang et al, 2000;Ikediala et al, 2002;Wang et al, 2001aWang et al, , 2002 for different fruit and agricultural commodities. Use of irradiation works if insect mortality is not required, but sterility or incomplete development suffice (Hatton et al, 1984).…”
