Product Does Not Freeze or Form Ice Crystals
When the product does not freeze, there are several possibilities other than a failure in the refrigeration system.
1. Product is very high in brix (sugar) or alcohol.
2. The torque between the auger motor and the frozen product is controlled by the torque sensor board measuring
the distance between the pins on the coupler and shaft. When the distance between the pins reaches the maximum
allowable distance, the compressor shuts off. The machine thinks the product thickness has reach the maximum and
shuts off the compressor. The illustration below shows some of the other possible causes for a false reading from the
torque sensor board.
