IV. Results of the Research and Suggestion for the Application
To mechanize the traditional process of shattering work for sesame. we developed a machine that can shatter the pod detached from stem. In order to complete the process of shattering with one round. we designed and developed rain proof drying stand.
Results of the Research and suggesLed application of sesame shattering machine and rain proof drying stand arc as follows:
1. In order to calculate tho optimal size of a sieve required for sesame seeds selection, we used 6 types of standard sieves from KS standard No 6~14 in the experiment. According to this test, the standard sieve No.8(size 2.36 mm) was determined as the oplimal for sesame seed selection.
2. Conventional shattering work for sesame seeds required 23 to 4 rounds of shttering. But if rain proof drying stand was used. sesame bundles could be fully dried regardless of weather condition and 1 round of shattering whether it was by hand or by machine, was enough to harvest. By using this stand, 2/3 of labor could be saved compared with the conventional procedure.
3. One rain proof drying stand could hold 44 sesame bundles.
One bundle was 8.4 cm diameter and compnse of 21 sesame plants. It needed three drying stands to cover 100 Pyung(330 m2)
4. In case of drying sesame bundles by tieing and making them stand in field, sesame seeds by natural opening of sesame pod are liable to be lost. The result of the test using rain proof drying stand showed thaL the total loss of sesame seeds during the dry period, accounts for 5% of the total production. It means that if rain proof drying stand is used, 5% of sesame seeds can be saved because shattered seeds by natural opening can be collected using by the stand.
5. The practicability and efficiency of rain proof drying stand for sesame seeds were recognized at sesame cultivation farms, so that the contract of technology transfer for commercialization was made with Gwangjin Corporation. Then, this Corporation was selected as one of the designated ventures by Gyeongsangbuk-do and is promoting distribution of this machine in main producing distriets.
6. If machine shattering was conducted at the conveying speed of 8.4m/min of side-hit shattering machine with horizontal input system and 18 bundles/min of input rate, relatively more inert matters such as detached pods or cracked stems were occurred than when the work was conducted by hands.
The percentage of shattering of machine using side-hit impact shattering method with horizontal input system was 90.3% at the 1st round, 6.4% at the 2nd and 3.3% at the 3rd round.
7. At a test trial of the side-hit shattering machine with the 21 bundle/min of the input rate, when the sesame bundles were inputted reversely the shattering performance of first round was 98.5 percentage, which was the 2.7 folds than that of horizontal input. The performance was calculated by excluding the seeds which was shattering by detached pods from the stems.
8. When the side-hit impact shattering machine with vertical input system was used, 97.2% of sesame was gained marking very high efficiency in shattering at the 1st shattering process. Subsequently, at the 2nd and 3rd shattering, the percentage of shattering was 2.8%.
9. According to the test, shattering was able lo be completed with 1 round by using machine on the condition lhat sesame plant was fully dried for enough time by using rain proof drying sland, while convcntional measurcs rcquired at least 3 rounds of shattering. Yet, there will be 2.8% loss if harvest is done by one round shattering using this shallering machine.
10. Working hour of shattering using by rain proof drying stand was shorter than that of the convenlional. Shattering machine by the drying stand could shatter more than 90% the sesame seed by one round so that it reduced the number of shattering rounds. Work hour of shattering per 10a was 18 minutes and 13.9 hours in shattering using by the stand and the conventional, respcetively.
11. Drying using by rain proof dryin stand improved the quality of sesame seeds. resulting in add 1,000 won value per kg seeds, and increased the yield by 1kg/10a by collecting the naturally shattered seeds. In addition, sesame farmers are not needed to bundle the sesame plants and elect by four bundles in order for the conventional drying
12. Mechanized shattering resulted in increase of sesame farm lncome by ahout 720.000 won/ha by reducing the operating cost. Letting the prices of shattering machine and drying stand are 2 millions Won and 6 millions Won, respectively. if the farmer cultivates more than 10 ha sesame. it is possible to get to the break even point of purchasing costs of two machines in the first year.
