Personnel Involved: (Persons at Risk)

Technicians
Title of Experiment / Procedure: Drying of Vegetable Products Using Fluid Bed Drier

Aim: To produce dried fruit or vegetables

Brief Description of Procedure:

After initial preparation the fruit or vegetables are placed in the drying chamber. Drying conditions of temperature and air flow rate are set using the controls on the front of the machine. Drying process is initiated by activating the start switch. At regular intervals the glass drying chamber, with the contents in situ, is removed from the machine and placed onto a mass balance to determine the weight loss. Food processing chemical additives may be used - in this case a COSHH assessment is required

Hazards identified:

1 Contact with sharp knive

2 Contact with hot surfaces / liquids

3 Chemical hazard

4 Electrical

 

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

1 Low : Use of safe working practice. (see Student Safety Handbook for guidance note - Working Safely with Knives)

2 Low : Exercise due diligence. Instruction in safe working practice provided

3 Low : Reagents provided are very dilute, Instruction in safe working practice provided

4 Low : Training in safe working practice

Information sources:
Instruction manual and Fisher Chemical Hazards Data Sheets

 

For CHEMICAL HAZARDS attach COSHH Assessment

Control Measures to be adopted:

Students trained in safe operation of equipment. Do not deviate from methodology shown in the practical sheet. Observe controls shown in COSHH assessment

Required checks and their frequency,on the adequacy and maintenance of control measures during the course of the experiment:

Continual observance of control measures required

Disposal procedures during and at the end of experiment:

Waste food disposed to waste food bin
Liquids containing food processing chemicals disposed to sink drain with much dilution
 
EMERGENCY PROCEDURES

If any of the substances or procedures identified overleaf is likely to pose a special hazard in an emergency, then identify below the action to be taken

Spillage/uncontrolled release: .

Liquid spillage should be mopped up promptly to remove slip hazard and excess flushed to drain.

Bulk materials should be carefully removed and disposed of as general refuse.
Fire:

none anticipated

If personnel are affected (fume, contamination, outdoor activity emergency etc) procedure to be adopted:

Minor cuts, burns and scalds require first aid treatment. More serious injury requires medical attention and technician to record incident in accident book
