Most of China likes to eat rice, and rice is also a large proportion of grain cultivation in China. With the renewal of agricultural machinery and equipment, many aspects of rice cultivation have been mechanized. Affected by the rainy and damp environment, the future rice drying machine will also play an important role in the rice harvest, rice drying machine market will also be a new trend.
Rice drying is an important part of grain harvest. Because harvesting in order to reduce the loss of field grain loss must pay attention to timely harvest, and timely harvest of grain moisture content is greater, if not timely drying will cause the grains rotten deterioration. Rice drying can be seen is a problem that can not be ignored.
In view of the status of grain drying equipment, combined with the needs of the rural market, the development of domestic grain drying equipment will show the following trends:
(1) Rice dryer production capacity should be large-scale development, the future need to develop processing capacity of 20-30 tons per hour of equipment.
(2) the design of the high moisture content of grain down to a safety standard equipment, a decline of more than 10%. To this end, there are two ways: First, the use of combined drying method, the drying method is about more than two combinations of the dryer into a new drying process, such as high-temperature rapid fluidization dryer to wet food warm- And then dry with a tumble dryer at a lower temperature. From the current world rice drying technology development, this is a trend. Second, the design of high-performance rice flash dryer.
(3) the application of advanced measurement and control technology to achieve the drying process to the direction of automation or semi-automatic development.
(4) high-temperature rapid treatment of high-volume high-moisture rice.
(5) To study the use of coal as energy, indirect and efficient rice drying machine is still the main direction, but also should explore new energy rice drying machine, such as microwave energy, solar energy and so on.
(6) rural rice drying machine should be small, multi-functional direction, requiring mobile convenience, simple operation, low investment and can guarantee the quality of dry rice.
