Despite the wide-spread applications of spray drying in production chemicals, food, and pharmaceuticals, accurate control development this unit remains an elusive task because complex interactions variables phenomena. In paper, we offer a computationally efficient closed-loop system with model predictive controller (MPC) where computational fluid dynamics (CFD) process is utilized to represent ...

The aim of the work was to evaluate effect hot air and infrared drying on content total polyphenols anthocyanin dyes in selected types small fruits. In we used chokeberry (Aronia melanocarpa Michx.) variety Nero, elderberry (Sambucus nigra L.) Haschberg, sour cherry (Prunus cerasus Fanal, red currant (Ribes rubrum Lake, black nigrum Triton, elaeagnus (Elaeagnus multiflora Thunb), raspberry (Rub...

drying characteristics of green pea (pisum satium) with an initial moisture content of 76% (db) was studied in a fluidized bed dryer assisted by microwave heating. four drying air temperatures (30, 40, 50 and 60ºc) and five microwave powers (180, 360, 540, 720 and 900w) were adopted. several experiments were conducted to obtain data for sample moisture content versus drying time. the results sh...

This research presents an experimental analysis of a counter flow spray drying process using water and skim milk as feed. The study was performed by examining the droplet size distribution sprays temperature profiles in dryer. influence air inlet temperature, mass rate, feed on temperatures dryer evaluated. evaporation deposition zones were found to be highly dependent size. obtained results sh...

Penelitian ini alat pengering Green House Effect (GHE) Vent Dryer. Penggunaan Pengering vent dryer memanfaatkan energi surya pada proses dianggap sangat solutif tepat guna. Akan tetapi karena terbatas oleh waktu maka penggunaan media penyimpan pan...

The manufacture of low density paper such as tissue and towel utilizes the creping process that consists of adhesively bonding the paper in wet state onto the surface of a smooth drying cylinder and scraping it off with a blade once the sheet is dry. In this paper, a fracture mechanics description of the creping process is presented. A mechanism of creping process is proposed as a periodic debo...

Investigations into drying kinetics of biomass in fluidized bed dryers are essential for the control processes, enhancing productivity and reducing energy consumption. However, there is limited research on characteristics at different bubble locations due to complex hydrodynamics around bubbles bed. In this paper, a new method proposed by combining electrostatic sensing digital imaging techniqu...
