1. Designated application and Overview
1.1 Designated application
GUTH mixers are designed and built solely for commercial and industrial use. They are used to mix, stir, disperse and
homogenize. The mixer is mounted to the tank with fittings. The fittings and tank must be capable of withstanding the
forces that occur.
Possible applications {XE "Possible applications"}:
- Stirring of liquids to prevent sedimentation of pulp and other solids, e.g. stirring of wine yeast for biological
acid decomposition.
- Production of uniform liquid mixtures even where various specific weights are involved.
- Clarification and homogenization when blending.
- Mixing of liquids with solid or gaseous products, e.g. to disperse clearing agents, sulphurous acid or carbonic acid.
- Emulsification of sterile preparations and homogenized distillates.
- Acceleration of reactions and dissolution processes, e.g. influencing of fermentation by dissolving sugar and
sugar solutions.
- Intensification of the efficacy of hot and cold influencing processes, e.g. uniform interspersion of liquids in
cooling processes.
- Activation of low-fermentation yeasts.

3.3 Built-in safety systems {XE "Safety systems"}
- The mixer is equipped with a one or three-phase, three or fivewire supply system with current-carrying N and
separate earth conductor (with yellow/green insulation).
This operating manual is an integral part of the mixer and must be kept readily at hand for the
operators at all times.
The safety instructions in it must be followed.
Also pay attention to the protective motor switch built into the motor as safety system;
see separate operating manual.
It is strictly forbidden to render any of the safety devices inoperative.
3.4 Safety precautions{XE "Safety precautions"} (to be carried out by the customer)
The customer must
- instruct his operating and maintenance personnel in the use of the mixer and its safety devices and
- ensure that the safety precautions are being adhered to. This operating manual is an integral part of the
