Gear pumps such as molasses pumps

Molasses is the residue after crystallization of sucrose. It is used relatively little in the confectionery industry, except for the production of licorice, which is the most used, and in the making of tricol sweets. In this product, the mallet adds color and flavor. In some dictionaries, definitions of treacle are broad enough to include golden syrup, but in this work, black means a black syrup made by diluting molasses. Golden syrup is a golden colored syrup produced by partially inverting cane syrup, which can be equivalent to invert sugar lightly tainted with molasses. Golden syrup is sometimes used in baking for flavor and color

Types of molasses pumps

Why use a gear pump to stir molasses?

Gear pumps do well in conveying viscous fluids (commonly known as very thick, viscous fluids or liquids). If you need to work with high viscosity fluids, a gear pump is one of your best options.

Another reason to use a gear pump to move the molasses is its flow rate. Gear pumps have a very controllable and constant flow rate, this is ideal for food processing and applications where precise amounts of liquid must be added through the pump.

Molasses gear pump brands

At All Pumps, we have several brands of gear pumps that are ideal for pumping molasses.

An example of a good gear pump for molasses is the Roper 2835 series, which is specifically designed for pumping viscous liquids up to 100,000 SSU.

Molasses physical properties – viscosity

The viscosity of a fluid is a measure of its resistance to flow. Unlike low-viscosity liquids such as water, molasses exhibits a smooth flow pattern, with the liquid particles staying in straight lines to form a series of concentric rings that cut through each other. The result of this type of flow pattern is that the fluid velocity next to the tube wall is nearly zero and the maximum velocity is in the central core of the tube. This is why the molasses tubes around the feed mill must be of the correct diameter and the pumps must be positive displacement at 100-200 rpm.

centipoise

Viscosity is a measure of a fluid’s internal resistance to flow. This is usually specified in centipoise or poise units, but may be expressed in other accepted measurements. Some of the conversion factors are as follows:

100 centipoise = 1
equilibrium 1 centipoise = 1 millipascal
