2017年6月16日 — Many thickener installations operate with water recovery below design limits largely through conservative control and low prioritization of thickener optimization. The operation of the thickener must accommodate fluctuations – control for disturbances – in the process feed stream to deliver a clear overflow and thickened underflow.

The thickener plays a crucial role in achieving the desired texture of the product. For e.g., a thickener that imparts a luxurious and velvety feel may be preferred for high-end creams. Whereas, a lightweight and non-greasy texture may be desired for lotions. The chosen thickener should align with the desired texture attributes of the formulation.

In cooking a filling, about 1.5 kg (3 1/3 lb.) of sugar should be cooked with the water or juice for every 500 g (18 oz.) of starch used as a thickener. Approximately 100 g (4 oz.) of starch is used to thicken 1 L of water or fruit juice. The higher the acidity of the fruit juice, the more thickener required to hold the gel.
