Evaluation of machines used for
crina processing.

Abstract: This study was carried out to compare and evaluate two different types of Crina processing machines (Pins and knifes systems). The experimental work was carried out at Dakahlia and Damietta governorates. The studied parameters included three different levels of feed rate (100, 120 and 140 kg/h) and three palm leaves moisture content (15, 35 and 50 %). The results showed that, increasing palm leaves moisture content from 15 to 50 % increased Crina fineness, machine productivity and total losses. While increasing feed rate from 100 to 140 kg/h increased Crina fineness, machine production and total losses at all levels of moisture content for the two machines tested. The Crina fineness, cost of production and net profit were increased, while the total losses were decreased for pin machine in comparison with the knife machine. However, the machine productivity was about the same for both machines.
In general, the pin type machine should be used at 140 kg/h feed rate and palm leaves moisture content of 35 and the highest net profi% to obtain the best Crina fineness, machine productivity t.
