TDAU has made the following products in the past, but due to a lack of demand, the Unit can only produce these machines through directed work with the Consultancy Department.  Click on the links below to see pictures of the devices which were formerly fabricated at TDAU.

Agricultural and Food Processing Products

  • Seed Treater: This mobile seed treater is designed for rural small- or medium-scale farmers who would otherwise plant untreated seeds from previous harvests.  Pedal-powered, this device can treat 15 kg of seed in 15 seconds with a team of two either with powder or liquid treatment.
