Batch Mixer Gericke GMS Compact
What this video shows
The Gericke GMS Compact is a double shaft laboratory mixer with usable volumes from 1 to 20 liters. Two horizontally arranged, superimposed mixing tools create a fluidized zone at the optimal Froude number of 1.1, while the low speed typical of the GMS family preserves ingredient quality. Interchangeable mixing chambers and tool free disassembly make it suitable for recipe development, pre mix formulation and small production batches.
What the footage shows
The video shows the Gericke GMS Compact, a double shaft laboratory mixer with two horizontally arranged, superimposed mixing tools that create a fluidized zone. It is built for usable volumes ranging from 1 to 20 liters.
Demonstrated solution
The GMS Compact works at the optimal Froude number of 1.1 and keeps the low speed typical of the GMS family of mixers, so ingredient quality is preserved during mixing. Mixing chambers are interchangeable and the mixing tools and the mixing chamber can be disassembled easily, which makes recipe changes and cleaning practical in a laboratory or pilot plant.

About this video
Gericke GMS Compact Double Shaft Laboratory Mixer
This video presents the Gericke GMS Compact, the laboratory scale member of the GMS double shaft mixer family. Gericke describes it as a double shaft laboratory mixer built for usable volumes ranging from 1 to 20 liters.
How the mixer works
Two horizontally arranged, superimposed mixing tools create a fluidized zone inside the mixing chamber. Material is lifted and folded rather than pushed, which distributes ingredients radially and axially in a short time.
The mixer operates at the optimal Froude number of 1.1 while keeping the low speed typical of the GMS family of mixers. Gericke states that this preserves ingredient quality during mixing, which matters when a formulation contains fragile particles or micro ingredients that must not be damaged or separated.
Built for development work
The GMS Compact is aimed at recipe development, pre mix formulation, pilot plants and small production batches. Its low minimum filling volume is the practical point: a laboratory can test a formulation without committing the ingredient quantities a production mixer would demand. Gericke names reduced research and development costs as the direct result.
Very short mixing times support agile product development, so several formulation variants can be evaluated in a single session.
Cleaning and changeover
Mixing chambers are interchangeable, and both the mixing tools and the mixing chamber can be disassembled easily. The unit is easy to clean and can be sterilized in place. In a laboratory that runs different recipes back to back, changeover time and cross contamination are the limiting factors, and both are addressed by the mechanical design rather than by procedure alone.
Installation requirements
The GMS Compact needs no compressed air and operates on standard 220V AC/50Hz power. It can therefore be placed in a laboratory or pilot area without additional utilities.
Where it fits in the GMS family
The GMS Compact shares the double shaft principle and the low speed operation of the larger GMS batch mixers, which makes it a scale up reference rather than a separate technology. A formulation developed on the GMS Compact is tested on the same mixing principle that a production GMS mixer applies.
