洛神葵去籽機之改良研發

洛神葵是臺東縣的特色作物，由於洛神葵去籽作業仍以人工進行，工作極為費時費工，本試驗乃針對以往開發的去籽機性能進一步改良，經過兩年研製，開發出鑽穴式洛神葵去籽機，其去籽率及作業效率，相較於以往的去籽機皆有較佳的表現。本機械的最大進料量為每分鐘69顆，進料方式以人工作業完成，本機械之去籽桿旋轉動力經由圓皮帶帶動，刀具旋轉速率約為350 rpm，具有切削的功能，可輕易切穿洛神葵的基部，並可將蒴果從果萼中推出。適期採收的洛神葵，剔除果萼直徑24 mm以下的小果及不良品，並立即進行機械去籽作業，則機械去籽效能最好；其去籽率可達85%以上，不會因為採收時段及地區的不同，而造成機械效率及功能的差異。果萼直徑以24、27、30、33、36及39 mm等相差3 mm的級距分級時，除24 mm以下者，其去籽率變化較大外，其餘24.1 mm以上者，各級距的去籽率皆可維持在平穩的數值區間内。

Roselle fruits are one of the characteristic plants in Taitung County. Since it takes much time and work that use the artificial way to remove capsule from roselle fruit, The Taitung District Agricultural Improvement Station was used to developing the roselle fruit coring-machine and hoping to reduce the production cost by mechanical operation, nevertheless, the efficiency and functions of the machine were not accepted by the farmers. To improve the previous machines, this experiment develops a drilling-type roselle coring-machine in two years. The functions and efficiency of the new invention are better than before. The input way of this machine is artificial. The maximum quantity of input is 69 per minute. The coring-knife rod is drove by a round belt with the velocity of 350 rpm; it can easily slice through the bottoms of roselle fruits and remove capsules from the calyxes. During the peaked harvest period of roselle fruits, after culling out the smaller than 24 mm and bad calyxes, and to execute the coring operation immediately, the machine has best performance; the coring rate can reach over 85%. The efficiency and function of the machine is not been influenced by different harvests and areas. When the diameter of calyxes are sorted by the grades of each 3 mm such as 24, 27, 30, 33, 36, 39, etc, except for 24 mm and smaller ones are instable in the coring rate, other grades of coring rate can all keep within stable values.
