The pipe connecting the RotaTherm® direct steam injection continuous cooker to downstream is called the Hold Tube.
The length and diameter of the Hold Tube is calculated as required for the processing of the product.
The purpose of the Hold Tube is to HOLD the product at the aim temperature for a required time to achieve the required product quality / regulation requirement.
The RotaTherm® direct steam injection continuous cooker heats the product to the aim temperature. The product then flows on into the HOLD TUBE, then continues downstream for cooling / filling etc.
The HOLD TUBE is a standard and essential component of the system.
