Pulses are very important in Indian food. About 80 % of the pulse production is
consumed in the form of dal and remaining 20 % as the whole seed and other forms.
However, the recovery of dal varies from 60-75%. The loss is about 10- 12 % edible portion
during milling operation. It significantly affects the cost and availability. Pigeonpea is the
most commonly used pulse among all pulses available. The hull is tightly attached to the
cotyledons via a thin layer of gums and mucilages along with uronic acids in the form of
calcium pectate. It all made the pigeonpea problematic for milling. In this context, efforts
have been made to develop improved methods and machinery to process pulses more
efficiently and economically by various research and development institutions in the country.
Among them IARI New Delhi had the Mini Dal Mill which could be operated at rural level.
The present study was undertaken to test the performance of the machine for pigeonpea
milling. The machine yielded finished product recovery of 72.83 % and hulling efficiency:
90.47% with pre-milling heat treatment at 85 0C for 4 minute. The hydrothermal treated lot
resulted finished product recovery: 74.96% and milling efficiency: 90.77 %. Further increase
of product recovery and dehulling efficiency was observed with scouring the kernel before
treatment. Cost of processing was found to be 1.25 Rs./kg and 1.60 Rs./kg for heat and
hydrothermal pre-milling treatment and milling by IARI Mini Dal Mill, respectively.
