Drying is an important process in the production of NPK fertilizers. The average water content August 2021 – January 2022 was 1.64%, still exceeding a good < 1.5%. high moisture resulted that review are needed drying through rotary dryer evaluation and observation by creating multiple linear regression math. thermal efficiency calculated based on actual data, which 73%, do not decrease signi...

In this paper a mathematical model for the soda ash drying process in pneumatic dryer was presented. The presents macroscopic aspect of process, two-phase, gas-solid system. is based on mass and heat transfer between gas phase particle, movement air particles through system, geometric characteristics system (fan, heater, dryer, cyclone). effects parameters, such as airflow, inlet temperature, r...

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...

Within a 53 home monitored sample, long-term energy use of electric resistance clothes dryers was sub-metered. Average measured dryer energy use was 3% of total household energy or 814 kWh/year. Hourly dryer electrical demand profile showed large coincidence with utility summer afternoon peak and significant increases over weekends versus weekdays. After collection of baseline data, electric re...

The purpose of the paper is to present a concept of energy efficiency and financial evaluation of counterflow dryer. Energy efficiency and many other efficiency indexes of the dryer and all additional devices like heater, heat exchangers, tubing and fans are calculated. Expert system provides also the financial evaluation of the investment. Many investments could be considered. The system provi...

In recent years, there has been growing interest to use computational fluid dynamics (CFD) for exploring dropletparticles interaction under the turbulent flow of air inside spray dryer systems. The final goal is to predict the dried solid particle size and mass flux distributions under the conditions of collision, coalescence and agglomeration of the droplets and particles. The coarse-grained s...

Fish as a source of animal protein is fishery commodity that prone to quality deterioration and spoilage after the fish caught, so it needs fast, precise correct handling keep its in hands consumers. There for necessary have process extends durability through drying. One drying alternative use Solar Air Heater with an Ultra Violet (UV) Dryer house by making building made transparent material fu...

Leakage of air in tumble dryers is an important parameter regarding the energy efficiency drying process. In general, are prone to leakage, therefore further investigation and optimization this field great interest. This study investigates quantifies leakage within closed-loop system in-situ household heat pump dryer. Each potential location was characterized by curve obtained either isolated o...
