Mahuwa nut cracker: Design & Insights from discussion

Observation

  • Ripened food is very soft and the inner portion can be eaten
  • Seeds vary in size. Average dimension is 3.5*2.5*1.5 cm
  • Specific pressure point (indicated with red star) which needs minimum force to break open the brown shell
  • Removal of brown shell from kernel is
    very hard as it sticks to the kernel very tightly.

Experiments

  • We tried perforating the seeds and then saw the effect on removal of the kernel. REMOVAL GETS MUCH EASIER
  • We tried soaking of the seeds in water. INSIGNIFICANT EFFECT OF REMOVAL ON INTACT SEED, SIGNIFICANT EFFECT ON PERFORATED SEED
  • We tried scrubbing against each other after making cuts on seeds. REMOVAL GETS EASIER
  • To be done: Heating the seeds, Boiling the seeds, Freezing the seeds, roasting the seed in sun light

Discussion with Prof. Kodar Patel

  • Earlier we came up with the seed on the nail-bed design
  • With the approval of the professor, we moved forward to devise a mechanism based on the above designconcept that we derived from our observation

Discussion with Sachin Panchal

  • A manual alternative has come up after the discussion with Mr. Pandal
  • A 3 plate device (25cm*25cm) which will include a nail-bed (with nail height of 4 mm), an iron net (which will allow not to stick the seed in the nails), and a heavy punch
