Bulk soybean grain mass temperature in warehouses with isolated vents and vent-exhaust combined systems

Temperatura da massa de grãos de soja a granel em armazéns com respiros isolados e em conjunto com exaustores

ABSTRACT:

This study aimed to compare the temperatures in the mass of bulk soybeans (Glycine max ) in warehouses with isolated vents and vent-combined exhaustion. A completely randomized design was used, with two treatments and ten repetitions. Treatments consisted of warehouse with curved vents and warehouse with curved + static exhaust vents. Each repetition contained the average of all readings in three days in all cables of the warehouse part under study, totaling 10 repetitions per month. The variable analyzed was the temperature in the grain mass in the lower, middle and upper parts of the warehouse from January to May 2012. The environment temperature and humidity were also registered. Static hoods, along with curved vents on the roof of the warehouse showed a tendency to reduce the temperature of the soybean mass with decrease in environmental temperature and increase in relative environmental humidity.

Key words:
static exhaust; Glycine max; post-harvest and curved vents
