This project was to create the lotus-seeds sheller by searching the basic factors of the lotus seeds, for example, diameter, ratio between long and short axes, moisture content and destruction of the lotus seeds. We set the razor inside an aluminum mold, install a soft transport belt above the mold.Then the mold and the belt had a speed difference;it makes the lotus seeds roll. When lotus seeds roll pass the razor, they were shelled. Installing a spring in the rear part of the mold makes the lotus seeds spring out. Therefore the skins and the seeds could be separated. We got a very satisfying result in a test of the lotus-seeds sheller. The conclusion was that for short lotus seeds, the shelling rate was 100% when tangential speed was 1.17m/s; when the tangential speed was 0.39~2.73m/s, the shelling rate was 94%. The production rate for the above conditions was 187kg/ hr. For long lotus seeds, when the tangential speed was 0.39~1.56m/s, the shelling rate falls down to 80% linearly. As the tangential speed was added to 2.34m/s, the shelling rate falls down to 74.7%. keyword: Lotus seeds, Shelling Machine, Speed Difference Principle.

碩士 === 國立屏東技術學院 === 機械工程技術研究所 === 84 === In considering that our country is going to join the WTO(
World Trade Organization ), and the trade liberalization, there
must be strong impact to the traditional agriculture of our
country. To improve agricutural productions and processings,
especially the automatization, the lotus-seeds sheller is one of
the efforts for the goal. In the past, the quantity of planting
never got increased due to the restriction of the manpower,
weather, and water supply. We have to improve the processing
methods and let mechanization increase the competitiveness of
Taiwan. For the moment, setting razor inside a modern mold
was the method for lotus-seeds shelling. This project was to
create the lotus-seeds sheller by searching the basic factors of
the lotus seeds, for example, diameter, ratio between long and
short axes, moisture content and destruction of the lotus seeds.
We set the razor inside an aluminum mold, install a soft
transport belt above the mold.Then the mold and the belt had a
speed difference;it makes the lotus seeds roll. When lotus
seeds roll pass the razor, they were shelled. Installing a
spring in the rear part of the mold makes the lotus seeds spring
out. Therefore the skins and the seeds could be separated. We
got a very satisfying result in a test of the lotus-seeds
sheller. The conclusion was that for short lotus seeds, the
shelling rate was 100% when tangential speed was 1.17m/s; when
the tangential speed was 0.39~2.73m/s, the shelling rate was
94%. The production rate for the above conditions was 187kg/
hr. For long lotus seeds, when the tangential speed was
0.39~1.56m/s, the shelling rate falls down to 80% linearly. As
the tangential speed was added to 2.34m/s, the shelling rate
falls down to 74.7%.
