Gain-in-weight versus loss-in- weight batching systems: what are the pros and cons? Jessica Stank offers expert guidance on selecting the appropriate batching system for your needs
electing the right batching system for your needs can make a huge difference in your ROI and efficiency. Tere are different factors to consider in gain-in-weight versus loss- in-weight configurations for batching systems, including cost, accuracy, speed, and downtime. Let’s dive into their differences, as well
as the pros and cons of each batching system.
WHAT IS A GAIN-IN-WEIGHT OR GIW BATCHING SYSTEM? A gain-in-weight batching system utilises multiple feeders to dispense into a single scaling vessel or container. Te vessel or
container typically uses load cells to measure the weight of the entire batch of dry ingredients as they are dispensed. Te vessel or container
is sized and designed based on a total maximum batch capacity for the ingredients assigned to the scale. It is called gain-in weight because it is measuring the weight of the ingredients as they enter the tared empty vessel, giving you the correct overall total weight for your batch.

micro ingredients For example, on a gain-in weight
micro ingredient scale, the individual ingredient bins will each dispense into a scale on load cells. Once the total batch weight is achieved, there is a transfer of those ingredients to the next step in the batching process, whether that is into a mixer or some other piece of equipment.

WHAT IS A LOSS-IN-WEIGHT OR LIW BATCHING SYSTEM? A loss-in-weight batching system uses a scale as a part of the ingredient storage hopper. As the ingredient is dispensed into an independent vessel or container, the weight loss is totalised until the desired amount has accumulated.
