Improved Swine Barn Ventilation Systems

Posted in: Energy by admin on | No Comments

This paper is based on a three year period of research. In year one, a computer-based data gathering system was installed in each of two 100-sow barns at the Prairie Swine Centre. The ventilation systems in the six rooms in each barn were nodified to enable a detailed study of air inlets, air distribution, heat exchangers, exhaust fans, and fan-heater controllers. In year two, major modifications were made to the continuous slot inlets in the farrowing and breeding/gestation barns. Year three of the project was intended as a clean-up year in which data analysis was to be completed.
What is minimum ventilation and what is the minimum ventilation rate for various swine barns? Tests with variable speed fans and fan controllers is included in this paper. Air inlets should be closed tight enough to maintain negative static pressure across the fan of 0.05 to 0.10 inches. Backdraft devices are needed on intermittenly operating fans to prevent the fan from acting as an air intake when the fan is not running. Energy efficiency is compromised when fans must overcome shutters that close by gravity. Dirty shutters or backdraft shutters will not affect the performance of fans operating at full speed.

Exposure to grain dust in many agricultural fields, so much that grain handlers don’t often pay too much attention to them and their potential effects. This extension pubication attempts to answer questiond such as: What are grain dusts? How are grain handlers exposed to grain dust? What are the human health effects of grain dust inhalation? and, How can repiratory illness f4rom grain dust be prevented?
