K.S.U. Pilot Mill Heat Treatment Preparation

1.	Empty trash containers.

2.	Remove sacked product or samples left from previous milling.

3.	The mill and cleaning house should be fairly clean with no piles of stock on floor.

4.	Check bag filters for stock.

5.	Close and cover air inlets and exhausts on roof.

6.	Close all windows and exterior doors.

7.	Cover freight elevator doors with paneling.

8.	Turn on cooling tower fan and Day Filter to circulate air in cleaning house.  Position portable fans where necessary for even heat distribution.

9.	Open doors between mill and cleaning house.

10.	Open covers and slide gates on empty storage bins.

11.	Turn off electrical scales.

12.	Spray Tempo 20WP on floor by exterior doors and in corners of each floor.

13.	Turn on heat and take temperature reading in the mill at the center of each wall at floor level.  Also take the temperature of heat vent on each floor as well as the temperature of the Smico filter, sifter stub, purifier 1, and the Bemis packer.  When the equipment temperature reaches 120EF, hold for 12-15 hours and then turn off the heat.  Heat vent temperatures need to be over 140EF.

In the cleaning house measure the temperature at the center of each wall at floor level if possible.  The equipment temperature needs to be 120EF for 12-15 hours.  Adjust heater position to try and effect more even heating.

General Comments
Incoming steam temperature from the university power plant needs to be at least 230EF or it will take more than 2 days to get the temperature desired.  There is no need to open sifters, conveyor bottoms and bucket elevator boots should be opened.  The inspection lids on top and the slide gates on the bottom of empty storage bins should be open.  Fire extinguishers need not be removed as long as the temperature does not exceed 150EF.

Outside weather can affect our heating process.  A cold, 40EF, windy day is not good.  March, July, August, or November are better.  Two heat treatments a year can provide good insect control.  After the facilities have cooled a thorough cleaning with the vacuum system is necessary.
