Most Chinese like to eat rice, while rice also accounts for a large proportion of China's grain cultivation. With the renewal of agricultural machinery and equipment, all aspects of rice cultivation have been mechanized. Affected by the rain and damp environment, the future rice dryer will also play an important role in rice harvesting, rice dryer market will also be a new trend.
Rice drying is an important part of grain harvest. Because harvesting in order to reduce the droplet loss in the field and must pay attention to timely harvest, and timely harvest of the larger grain moisture content, if not timely drying will result in mildew deterioration of the grain. Visible rice drying is a problem that can not be ignored.
In view of the status quo of cereal drying equipment in our country and the needs of the vast rural market, the development of domestic cereal drying equipment will show the following trends:
(1) The production capacity of rice dryer should be large-scale development, the future need to develop capacity of 20-30 tons per hour equipment.
(2) Equipment designed to reduce high-moisture cereal once to safety standards requires a reduction of more than 10%. To this end, there are two ways: First, the use of joint drying method, that is, more than two drying methods of drying machine combined into a new drying process, such as the use of high temperature fast fluidized dryer wet food preheated, Re-use drum dryer at a lower temperature for drying. From the current development of rice drying technology in various countries around the world, 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-automation.
(4) high-temperature rapid processing of high-volume high-moisture rice.
(5) It is still the main direction to study the coal-fired indirect energy-efficient rice dryer. At the same time, new energy rice dryers, such as microwave energy and solar energy, should also be explored.
(6) Rural rice dryers should be developed in a small and multifunctional direction, requiring easy movement, simple operation, low investment and ensuring the quality of dry rice.
