04-04-2014· The mixture of the food waste with sawdust (70:30) was dried using the microwave–thermal air (1 kW, 200 °C) The drying process led to the final moisture content of 58 %, which was the lowest level (required <10 %) with 10 min operating period In this moisture content, lower heating value for the RDF was 5,660 kcal/kg...
01-03-2012· The drying temperature significantly affected the moisture change in sawdust Increasing the drying temperature in the tested range increased the drying rate of sawdust and reduced the time required to achieve specific moisture content The initial moisture content of poplar sawdust was determined as 125% on wet basis...
o Drying behaviour: A short preheating period + a short constant rate period + a long falling rate period o Original sludge → Mixed sludge: Drying rate ↓ o Sawdust addition (1) Drying rate ↑ (2) From mass ratio of 2/8, the drying rate exceed the drying rate of original sludge Sawdust addition has a positive impact on the drying process...
Why to Dry Biomass Materials Fresh wood log or wood sawdust contains too much moisture In certain circumstances the moisture can be evaporated so easily that wood materials will be shrunk,cracked,bent or even mildewed, and thus wood pellets or briquettes density and quality will be badly affectedThat’s why drying machine is necessary prior to the pelletizing or briquetting stage...
The moisture of the material will change with the pressure of the external force For example, the loose sawdust and the slightly squeezed sawdust will get very different moisture test result In fact, there is a incredibly easy way to measure the moisture Weigh a kilo of sawdust, put them in a microwave oven, after drying, weigh the sawdust ....
