The purpose of a false bottom in a mash tun

The false bottom in the mash tun is used in the brewing process to separate the solids from the liquids during mashing. The purpose of a false bottom is to allow the liquid portion of the mash, which contains the fermentable sugars, to flow through and exit the mash tun, while the solids, such as grain husks and particles, remain in the tun. This helps to ensure that the mash is properly mixed and that the sugars are extracted from the grains efficiently.

The process is just like this:

1. As the liquid is drained from the mash tun, the grain solids are collected on top of the false bottom screen, while the liquid passes through the holes and is collected in a separate container.

2. By preventing the grain solids from entering the wort, the wedge wire false bottom ensures that the enzymes in the malt can convert the starches into fermentable sugars more effectively. 

The false bottom can be installed in different ways depending on the specific design of the mash tun and the brewing process being used. Some common designs include a removable false bottom that can be lifted out of the mash tun for cleaning or a fixed false bottom that is integrated into the mash tun and cannot be removed.

We can custom design various false bottom screens suitable for different types of mash tuns. Welcome to contact us at any time!
