Abstract

The effectiveness of different drying systems used for the dehydration of certain fractions of biodegradable municipal solid wastes with a high moisture content (fruit and vegetable remains) was analyzed. Some tests using small amounts of the material were carried out in natural and forced convection ovens. For larger quantities of wastes, a discontinuous cabinet dryer and a continuous rotary dryer were used. With these dryers, the moisture content was reduced from 800 to 100 g kg(-1). It was verified that the continuous rotary dryer was the most efficient type of equipment studied, since it allowed a dried waste to be obtained with better nutritional and microbiological qualities and in accordance to the specifications of the products for animal feeding.

摘要

分析了用于对某些高水分含量的可生物降解城市固体废物（果蔬残渣）部分进行脱水处理的不同干燥系统的有效性。在自然对流和强制对流烘箱中对少量该材料进行了一些试验。对于较大量的废物，则使用了间歇式箱式干燥机和连续式回转干燥机。使用这些干燥机，水分含量从800克/千克降至100克/千克。经证实，连续式回转干燥机是所研究的最有效的设备类型，因为它能够获得具有更好营养和微生物质量且符合动物饲料产品规格的干燥废物。
