Mechanical intervention for reducing dust concentration in traditional rice mills

Mechanical intervention for reducing dust concentration in traditional rice mills

A huge number of workers are employed in traditional rice mills where they are potentially exposed to dust. In this study a dust collection system was developed to capture the airborne dust in the rice mill. The feeding and sieving section of the mill was identified as major dust creating zone. The dust was captured by creating suitable air stream at feeding and sieving sections of the mill and...

Gasification-based Biorefinery for Mechanical Pulp Mills

The modern concept of "biorefinery" is dominantly based on chemical pulp mills to create more value than cellulose pulp fibres, and energy from the dissolved lignins and hemicelluloses. This concept is characterized by the conversion of biomass into various biobased products. It includes thermochemical processes such as gasification and fast pyrolysis. In mechanical pulp mills, the feedstock av...

evaluation of mechanical damaged starch in some wheat flour mills

to evaluate the flour quality 10 flour plants were selected in iran, tehran province. two kinds of flour were sampled from each plant (flour with 87% extraction named straight-run- flour as well as patent flour). samples were analyzed for their moisture content, ash, maximum viscosity of dough, particle size, falling number and the amount of damaged starch, which was determined through maltose ...

Dust and flour aeroallergen exposure in flour mills and bakeries.

As part of an epidemiological study among workers exposed to flour total dust and flour aeroallergen concentrations were measured with personal samplers over a workshift in three large bakeries and four flour mills and packing stations. In the bakeries geometric means for total dust concentrations ranged from 0.4 mg/m3 in the bread wrapping area up to 6.4 mg/m3 at the dough brake. The flour aer...
