From field management to harvesting, drying, storaging and processing of rice, the reasons for creating cracked rice, the effects of cracked rice on the percentage of head rice and the taste of polished rice as well as the solvable countermeasures were analysed in order to raise the knowledges to the cracked rice.

Firstly,the basic character of the rice drying is detailedly shown in this article,and the present situation of the rice-cracked disciplinarian is systemically analyzed;put forward the measures to reduce the problem of the rice-cracked,finally the article summarizes up the prospect of the rice drying.

Detection of crack in brown rice kernel using wavelet transform;

Setting of the Measuring Standard of Rice Kernel Fissuring;

Special emphasis is put on the fissuring of rice kernels during drying.

Traditional drying of paddy rice has the disadvantages of great energy consumption,the low germination rate and high fissure ratio,applying the magnetic field into the drying process can lower the humidity and keep good quality of paddy rice fast and economically.
