1. INFLUENCE OF DIFFERENT TEMPERATURES AND AIRFLOWS ON DRYING OF NATURAL AND PULPED COFFEE
ABSTRACT This study aimed to evaluate drying kinetics for natural and pulped coffee, using different temperatures and drying airflows. For the conduction of the experiment, coffee fruits (Coffea arabica L. cv. Topázio) were harvested manually, selecting only ripe fruits and subsequent to the hydraulic separation. For drying the coffee, use a mechanical drye

2. MATHEMATICAL MODELLING AND IMMEDIATE AND LATENT QUALITY OF NATURAL IMMATURE COFFEE UNDER DIFFERENT DRYING CONDITIONS
ABSTRACT This work aimed to study the immediate and latent effects of different relative humidities on the quality of dried coffee fruits, describe the drying kinetics of natural immature coffee (Coffea arabica L.), and evaluate the mathematical model that best fits the experimental drying data. The drying was carried out in a fixed layer dryer coupled to a

3. Drying coffee spent ground in Cyclonic Dryer / Secagem da borra de cafà em secador ciclÃnico
Due to trade liberalization, competitive scenery was created in relation to the exigencies with the environment preservation. Industries began to worry about the waste treatment and by-products generated by the in activity. The coffee spent ground, by-product of the coffee industry, previously discarded without commercial value, is now seen as solid fuel, a

4. SECAFÉ Parte II: recomendaciones para el manejo eficiente de los secadores mecánicos de café pergamino
A Microsoft Visual Basic 6.0 parchment coffee drying program was developed. Two separate programs, based on Thompson and MSU models and using Cenicafé's coffee parameters were successfully tested for the evaluation of the performance of all mechanical coffee dryers existing in Colombia. Based on the good results, a unique simulation program was implemented

6. Influência do processo de secagem por pulverização mecânica (spray dryer) no tamanho de partícula e densidade aparente do café solúvel. / The influence of the mechanical spray drying process on particle size and bulk density of instant coffee.
O Brasil é um grande produtor e consumidor de café. A bebida é a segunda mais consumida no país. O café solúvel é uma alternativa para o consumo diário visto que dispensa todo aparato de preparo da bebida, sendo necessária apenas água quente. O tamanho de partícula seca está diretamente ligado à densidade aparente do produto. Foram realizados te

8. Technical and economic analysis of corn drying in rotary dryers / Análise técnica e econômica da secagem de milho em secadores rotativos
The objective of this work was to analyze the feasibility of rotary dryers with radial air distribution, which is used in coffee processing, for corn drying. Energy consumption, drying cost and final quality of the product were evaluated. The drying air temperature was maintained at 80 and 100 C. The drying systems consisted of a commercial rotary dryer and

11. Performance of mechanically shaken indirect contact atmospheric dryer in drying pastelike materials
Pastelike materials are encountered in many technological processes in chemical, pharmaceutical, foodstuff and natural product industries. The most important factor in the drying of this type of materials is the nature of the moisture bonding that occurs. Because of the different characteristics of pastes, it is impossible to recommend a universal type of dr

12. Preparo, caracterização e avaliação funcional de microcapsulas obtidas por spray drying, contendo extrato de cafe crioconcentrado. / Preparation, charaction and funcional evaluation of microcapsules obtained by spray drying, containing cryoconcentrated coffee extract.
Microencapsulation using spray dryer has been widely used in food industry, seeking core protection. Nowadays, the gum arabic and maltodextrin have been used as wall material, but cashew gum was still not studied as a microcapsule for this purpose. This way, the objective of this work was studied the volatile retention of coffee extract during microencapsula
