Resumo
Losses in the mechanical harvesting of industrial
tomatoes, depending on the levels reached, may considerably
reduce the yield of the planted areas. This study aimed to
evaluate the effect of settings of the rotary separation system
on losses observed during the mechanized harvesting process.
The statistical design was completely randomized, in a factorial
scheme with four replications, where each plot consisted of the
combination of three rotation levels (6 rpm, 24 rpm and 18 rpm)
with three vibration frequencies (0.83 Hz, 2.50 Hz and 4.17 Hz)
from the separation system. The recorded losses were divided into
branch losses, fruit losses on the soil and total losses. Sequential
and control charts for individual values and variable ranges
composed by the upper and lower limits of control and average
were used as a tool of statistical process control. The results
showed that the total losses incurred are outside the control limits
and acceptable standards for industrial tomato crops. The use of
higher levels of rotation and vibration in the harvester separation
system provided a higher harvest efficiency
