Pasteurization Systems

More Information

What to know: Batch Pasteurizers vs. HTST (High Temperature Short Time):

Schlueter makes and sells these two types – batch pasteurizers and high-temperature short-time (HTST) units.

1. Batch pasteurizers raise milk to a certain temperature, such as 145 degrees F, for a relatively long period of time –30 minutes, as example.
2. HTST units do what their name implies – they raise milk to “High Temp” about 161 degrees F and maintain it for “Short Time”, about 15 seconds. The batch and smaller HTST units are self-contained, usually needing only a 240-volt service and one or two water lines to operate. larger HTST units need equipping with a boiler to heat the water used in the pasteurization process.

Safgard Dual Temperature Pasteurizer:

Instructions for Heat Treating Colostrum (Use Dual Temperature Model P3000):

1. Remove milk pail and fill the machine with water to the level of the drain plug outlet. Both thermostats must be covered with water.
2. Flip the control switch to activate the thermostat without the buzzer and plug in the cord to activate the water bath thermostat
3. Set the thermostat kick off at 130 degrees
4. Monitor the water temperature with thermometer. The machine may drop 3 or 4 degrees in temperature, but will still maintain the 135 plus or minus needed to effectively heat treat colostrum. Since a buzzer is not added for the heat treat thermostat, the frying sound emitted by the heating element may be used to determine temperature kick off, which should be 130 degrees on the thermometer. Thermostat may be adjusted up or down accordingly.
5. Pour the colostrum in a good canning-quality glass container with lid. Any size jar from a half pint to a gallon will work.
6. Place container with the colostrum in a water bath. It does not matter if the container sinks or floats. The machine is a simple water bath and the temperature does the job.
7. As soon as temperature reaches 130 degrees, set a timer for one (1) hour.

*It is advisable during kidding season to check both thermostat temperatures at least once per week. Heavy use or a bump of the machine can change the thermostat setting by several degrees.
