Demonstration of BRRI Batch Drier in Farmers' Field

Abstract/ Executive Summary:

Out of 14 driers only 5 have been used and about 550 mounds of paddy were dried. Users reported slight smoky taste and a high breakage in the milled rice. Rice millers would like to use the driers if breakage and smoky taste in the milled rice could be minimized. They also pointed out the higher drying cost compared to that of sun drying but at the same time acknowledged its utility when there is continuous rain. They also commented that drier as an independent establishment would not be profitable as it could not offset the traditional drying cost. Probable causes of low use of driers may be as follows: 1. Intermittent rainfall which allows farmers and millers to dry their paddy in the sun. 2. High establishment and operating cost compared to that of sun drying. 3. Farmers awareness about grain loss due to lack of drying is poor. 4. High breakage and smoky taste in the milled rice. 5. Extra botheration for collecting rice hulls, operator etc. for a couple of days in a year. 6. Lack of proper training of the operator.

Start Date: 01-07-1982

End Date: 30-06-1983

Program Area: Farm Mechanization

Non-commodity: Farm machineries, Demonstration

Objectives:

To evaluate the performance of BRRI batch drier

Methodology:

BRRI developed batch type driers were installed in the Rice Mill, Research station, Government seed farm during 1978 through 1982 period have been used for general maintenance and repair work during Boro’83. Potential use of these driers is expected in the rainy season which coincides with Boro (late) and Aus harvest. A post season visit was made in August’83 to the drier sited and drying data were collected.

Achievement/Findings:

Results of the extension of rice driers are poor as only a few driers have been used during the reporting period. Further modification of the drier is needed for future used.
