Return to index page
Silverson Homogeniser Operating Instructions
 

Personnel Involved: (Persons at Risk)

Staff / Students
Title of Experiment / Procedure:

Aim: To produce evenly mixed liquid foods with consistent texture by homogenising liquids
Brief Description of Procedure:

A rotatable blade located inside a suitable screen (dependant upon food type) is lowered into the food to be mixed / homogenised, when switched on the blade draws into its centre the food being treated and shears it through the screen. This re-circulating process is continued until the food reaches its required degree of mixing / homogenisation.

Hazards identified:

1 Contact with rotating shaft, homogeniser head

2 Manual handling, raising and lowering of the homogeniser head for adjustment

3 Noise, measured at around 85 dBA

4 Electrical equipment

 

Associated Risks: (level: low, med, high)

1 Low: Switch off and lock-out working when changing screens and cleaning. Training in safe operation

2 Low: Training in safe adjustment

3 Low: Ear defenders must be worn at all times when operating this machine. In normal operation exposure time can be up to 10 minutes hence short period of exposure (8hr TWA 85 dBA, first action level. Ref HSE noise at work regulations.)

4 Low: Instruction in safe use of equipment
