Study of tray and pulsed fluidized bed drying of brewer’s spent grain

Abstract

Article Highlights • Brewer's spent grain is the major residue from beer production • Drying brewer's spent grain prolongs its storage time and reduces its mass • Drying of brewer's spent grain was performed in a tray dryer and in a pulsed fluidized bed dryer • Semi-theoretical models adjusted well to the experimental drying curves • Drying in pulsed fluidized bed was faster than in tray dryer

Effect of Dynamic Bridging on Homogeneous Grain Movement in a Microwave Processing Zone

“…Thus, one area of the grain in the microwave field might be processed more than another .. In order to ensure the hydraulic mode of grain flow, the unloading hopper parameters (6) and the dimensions of its outlet hole (7) shall comply with certain requirements. The following size values of unloading the hopper basement were selected in accordance with the dimensions of the convective-microwave zone: 400 mm = 0.4 m and 1500 mm = 1.5 m, for width (Sch) and depth (Dl), respectively.…”

“…Various types of grain dryers are used depending on the specific grain crop under treatment and on the required processing rate. These include vertical silage-type dryers [5], tray-type grain dryers [6], grain dryers with free fall of feed [7], and plane-table grain dryers [8]. It is worth noting that grain drying is an energy consuming process.…”

Effects of pretreatments on drying of Turkey berry (Solanum torvum) in fluidized bed dryer

“…The high moisture content of agro food-stuffs makes it difficult to preserve for a long time. Removing the water content by drying, extends the self-life of those products as a result, it prevents the growth and reproduction of microorganisms [2][3][4]. Furthermore, food-stuffs are susceptible to drying environments such as processing temperature, inlet fluid flow, relative humidity that can lead to the quality degradation of the products by oxidation, changes in color, and loss of physical and biochemical properties [5].…”

“…Drying greatly decreases food-stuff weight and volume, and brings many advantages such as reducing packaging and transport cost and storage space [2][3][4]. Commercially many kinds of dryers were available in the market like Convection dryer, fluidized bed dryer, microwave dryer, drum dryer, freeze dryer, solar dyer, and infra-red radiation dryer, etc.…”
