[0002]

[Prior art]

 At present, 1,500 MT and 200 MT of hemp seeds and mustard seeds, for example, are used as ingredients for spices and feed for birds, etc., respectively, but the amount of each import is increasing year by year. There is a tendency. Such hemp and mustard seeds are used as the above-mentioned materials, but on the other hand, they are one of the major social problems of illegal cultivation of cannabis and opium / morphine by germinating them naturally and artificially. In addition, the number of illegal cultivation of cannabis and the like tends to increase in proportion to the increase in the import amount of hemp and mustard seeds. One of the main reasons for this is the imperfect germination prevention process for raw hemp and mustard seeds imported to Japan.

For this reason, it is extremely important to completely prevent germination of raw hemp and mustard seeds, but conventionally, an indirect heat treatment method using hot air has been adopted.

This is because it is difficult to sufficiently evaporate and dry the moisture inside the fruit from the outside even if the hemp nut or the mustard fruit in the rotary drum is heated from the outside of the drum by hot air.

[0006] In addition, these hemp seeds or mustard seeds are natural fruits, the particle size of which is not constant, and large and small fruits are present. In this case, small grain seeds are used as a reference. When heated, the large grains become under-heated, which may cause some germination.

Therefore, according to such a germination-preventing treatment of the prior art, in a state where the water which is a factor for inducing spontaneous germination remains, in some cases, a germination is promoted by an incomplete drying treatment. , Hemp seeds or poppy seeds will be on the market. And this will be a cause of illegal cultivation of cannabis and the like.

Further, in such a conventional germination prevention treatment, there is also a problem that the heat treatment time by hot air becomes long and the quality of hemp and mustard seeds as a material such as spices and foods deteriorates. there were.

The present invention has been made in order to solve the problems of the prior art, and provides a device for treating so that germination of cannabis or mustard seeds is completely prevented.
