Mfundo yogwirira ntchito:
Makina ochapira mpunga wa chiponde amapangidwa ndi chipangizo chopangira mphamvu, chimango, chodyeramo chakudya, chodzigudubuza, ndi chokopera choyamwa. Zimagwira ntchito pogwiritsa ntchito njira yopatsirana ma friction friction, yomwe imasenda mpunga wa chiponde utatha kuwotcha mpaka chinyezi chosakwana 5%. Khungulo limachotsedwa popima sieve ndikuyamwa, zomwe zimapangitsa kuti njere za chiponde, theka la njere, ndi ngodya zosweka zisiyanitsidwe. Ndi ntchito yake yokhazikika, zokolola zambiri, mlingo wochepa wa mpunga wosweka, ndi zina zabwino, makinawa ndi otetezeka komanso odalirika.
Mapulogalamu:
Makina ochapira mtedza wa peanut amagwiritsidwa ntchito kwambiri popanga zinthu zosiyanasiyana za mtedza, kuphatikiza mpunga wokazinga wa mtedza, mpunga wokometsera wa mtedza, maswiti, maswiti, mkaka wa mtedza, ufa wa peanut, phala zisanu ndi zitatu, mpunga wa mtedza, ndi zakudya zamzitini. Zimathandizanso poyambira kupukuta khungu.
Ubwino:
Makinawa ali ndi maubwino angapo, kuphatikiza kupukuta bwino komanso kusenda kwambiri. Ndiwosavuta kuphunzira, kugwiritsa ntchito, ndikupulumutsa nthawi, potero kumapangitsa kuti ntchito ikhale yabwino. Mpunga wa mtedza sungasweke mosavuta posenda ndipo umakhalabe ndi mtundu, michere, ndi zomanga thupi. Ili ndi dongosolo loyenera, ndipo ikagwiritsidwa ntchito ndi makina angapo, imatha kugwira ntchito bwino komanso modalirika, kupereka moyo wautali wautumiki.
