    When I visited Changchum on July and August in 1982, I investigated the equipments and the usage of the rice milling plant. Thogh the sizes of the equipments are similar to those in Japan, the operation and the performance are different. Technical check of some equipments was conducted in comparison to those of Japanese type, and the following results were obtained.
1) Because the received paddy contains many small stones and grains of different variety, the husking ratio is lowered; making use of many pre-cleaners necessary.
2) There are many cases in which the paddy storage bins are temporarily constructed. This system is considered inappropreate due to :
i) the occurance of much grain loss,
ii) much labor is necessary to construct and destroy the bins.
3) Due to the difference in the ratio of revolutioq difference and the method of separation of brown rice and paddy, the husking efficiency becomes about one half in comparison to Japanese ones.
4) The grinder type rice milling machines of which the grinder No. is # 24-30 are used in order to :
i) decrease the rice breakage,
ii) increase the milling ratio.
