TAILIEUCHUNG - The study scientific farming "RICE DRYING TO MECHANICAL Minimise"

Intensive Agriculture: The agriculture sector is specialized in all aspects of agricultural production, including machinery used in farming, animal husbandry, or in processing agricultural products . Intensive agricultural production with large input sources, including the use of chemicals kill worms, herbicides, fertilizers, selective breeding and research of new varieties and a high degree of mechanization. | This training manual brought to you by CARD project VIE026 025 - Nong Lam University HCMC - The University of Queensland Australia TRAINING MANUAL MECHANICAL RICE DRYING TO MINIMISE storage period less cracked grain higher head rice yield. 2. More active less weather dependence alternative sun and rain flood. Sun drying high labor cost ijZA large area required for drying weather dependent COMPARISON OF EFFICIENCY 3. Less grain losses due to attacks of pests rodents poultry. Cost Mechanical rice drying cost is not too high as compared to sun drying Mechanical drying 40-50 VND kg Sun drying 30-40 VND kg sunny day 120-130 VND kg rainy day . Quality Mechanical dried rice is better in terms of Increase in head rice recovery Decrease in grain losses. Economic efficiency higher benefit than sun drying 66-76 VND kg after expenditure deduction . Mechanical drying less labor required more active. 4. Cost-saving and issues regarding labor force small space required for drying.

Paddy loading Load a uniform moisture content paddy to dryer set-back feeding don t trample upon paddy level the surface of paddy load. Thickness of paddy for flat bed drying airflow upward 30-35cm reverse downward 60-70cm. 2. Furnace burning Husk furnace Spread husk set husk on fire until husk burned out start the dryer. Coal furnace Use fire-wood to set coal on fire - start the dryer. 3. Drying air checking Drop a paper on the surface of paddy and then speed dryer up gradually Drying-airless if a paper is still on the surface of paddy A paper flies upon the surface of paddy 2-3 cm indicating drying air sufficiency Drying air should be .
