Tom Tabler I will be glad to provide information on our grinding process. We have been experimenting for around six months at this point and we are still in the process of determining what our most efficient carbon sources are concerning the least amount of time required to complete the compost cycle. I will try to get you something together this week as far as cost and how we have set our syst ...

My experience has shown that intermittent pump shutdown has two downside effects. If the pads are not clean you may not be getting the water saturation needed and depending on the water supply you may get excessive calcium or scale build up on the pads reducing efficiency.

This is a little off topic but still involves composting. We have currently started a process of grinding our mortality with a mixture of sawdust sandwiched between layers of straw. So far the composting has been excellent with no bones. The final product actually composts further over the time it takes to fill a bin. Final moisture rate is around 30 percent. The most advantageous result is t ...

I understand the concept but wonder if this would work with battery systems with cross ventilation where the air speed would not be as high and water droplets wouldn't reach birds or allow drying as the birds are more compact.

Ling Yoke Kooi Today's variable speed drives are compatible with nearly every fan motor provided. The drives become an accessory for a single fan or multiple fans. As long as the drive matches the total electrical load of the fans, they can achieve great flexibility. It is a good idea to limit the variable reduction to around thirty percent of the fan maximum performance data on the low side.

Variable speed fans can have a profound impact on this type of problem. I have found that by reducing the air volume by slowing fan speed rather than intermittent cycling of exhaust fans the temperatures are much more stable and don't have the cooling effect that typically occur when fans are running at full speed intermittently. Variable fans also prevent the heating and cooling cycles which ha ...

Dr. Mike Czarick, thanks for bringing this topic to the forefront. I think variable fan control is underutilized in the poultry and other animal industries. There is so much variability and savings to be had in several area's. Just the use of soft start capability and off the shelf equipment savings are well worth the look. VFD's are great at solving problems and tracking energy usage. They are be ...

Have one building using all variable speed fans. Cycling between 30% and 100% depending on summer and winter conditions. Ventilation at extremely low temps much more stable and comfortable by elimination of minimum cycling of fans at these temps. Fans are also controllable by automated environmental systems meaning that ventilation can be lowered even during evaporative cooling season increasing c ...
