Perspective Analysis of the Physical and Engineering Properties of Coriander Seed at Different Moisture Contents

Coriander (Coriandrum sativum L.) is an important leafy vegetable of family Umbelliferae with small fruits of great medicinal and nutritional value used as spice and condiment. As a marginal spice crop it is cultivated worldwide since centuries but its genetic diversity has rarely been documented. Threshing is one of the major problems associated with coriander production in India. In spite of the food and nutritional importance of the crop to human diet, its threshing has been and remains a serious problem to the farmers. The techniques for threshing coriander in most rural areas are still the traditional methods of seed separation which are uneconomical, labourous and time consuming. Under the present investigation coriander crop was selected for study. Physical, aerodynamic and frictional properties of above seeds were determined in order to decide parameters for the purpose of designing and performance evaluation of a thresher to threshing coriander.
