Description

A Rice Drying Device with High Energy Utilization Efficiency

technical field

The utility model relates to the technical field of rice drying, in particular to a rice drying device with high energy utilization rate.

Background technique

Rice is one of the main food crops in my country and is widely planted in most provinces. Newly harvested rice is not easy to store because of its high water content (25% to 30%), and its quality deteriorates quickly. According to statistics, my country loses about 2.5 million tons of rice every year due to failure to dry in time, which is equivalent to the annual consumption of 10 million people. At the same time, the energy consumption applied to rice drying accounts for 64% of the total energy consumption of rice production and processing, which is a high energy consumption unit operation. Today, as the area of arable land continues to decrease and food security and energy crises become more prominent, timely, high-quality, low-energy drying of rice after harvest has become an important research topic in the field of grain drying.

The biological characteristics of rice itself determine that it is a heat-sensitive material that is difficult to dry. At present, the drying methods of rice mainly include natural drying and mechanical drying. Restricted by economic conditions, the vast majority of farmers in my country use natural drying to dry their own rice. This drying method is often affected by weather and biological factors, especially in southern China, where rice harvesting often encounters rainy weather. Due to the weather, fresh rice is prone to mold or germination because it cannot be dried in time, resulting in food waste.
