Core Equipment Types and Their Functions

Understanding the roles and technical specifications of core small brewery equipment is essential for optimal process performance. Below we discuss the primary components and their engineering details.

Mash Tun

The mash tun is typically a jacketed vessel designed for the enzymatic conversion of starches into fermentable sugars. Precision temperature control, achieved through steam jackets or electric heating elements, maintains the mashing temperature typically between 62°C and 72°C to maximize enzymatic activity.

Internal manifolds or sparge arms facilitate even water distribution, and an agitator may be employed to promote homogeneity. Thermal insulation and carefully designed vessel geometry support energy efficiency.

Lauter Tun

The lauter tun separates malt solids from wort; its bottom is fitted with a false bottom, allowing wort to be drained while retaining grain bed integrity. Flow rate control through gradual draining and sparging ensures clarity and extract efficiency.

Materials must be food-grade stainless steel with smooth welds to prevent bacterial contamination. Engineering-wise, hydraulics and fluid bed dynamics are critical considerations for lauter tun designs.

Boil Kettle

Boil kettles bring the wort to a rolling boil, typically lasting 60 to 90 minutes, for sterilization and hop extraction. Steam jackets or direct fire burners provide heat, and agitation systems prevent scorching.

Vessel size and agitation methods influence hop utilization and clarity. Vapor handling systems may be integrated to capture and condense volatiles.
