Food Processing Plant Design & layout
operate and maintain. Horizontal clearance of at least 1.5 m should be left between
exchangers or exchangers and piping. Floating head heat exchangers require an
installation length of at least 2.5 times the tube length. Air cooled exchangers are
located adjacent to the plant section they serve.
Pumps in general should be located close to the equipment from which they take
suction. Changes in direction of the suction line should be at least
0.6 m from the pump. As far as possible, clearances and piping should provide free
access to one side of the motor and pump. Clearances between pumps or pumps and
piping should be at least 1.2 m for small pumps (18 kW) and 1.5 m to 2 m for large
pumps. Pumps handling hot liquid (60 °C) should be at least 7.5 m from pumps
handling volatile liquids.
8.2.4 Space determination
In the layout planning process the space is allotted to different activities.
The theoretical minimum space, a plant can occupy, is the total volume of its various
components. Various constraints prevent the attainment of this minimum. Such constraints
include allowing adequate clearances for access during operation and maintenance and to
allow safe operation. While determining the space consideration should be given to the
following.
Operating equipment
Storage
Service facilities
Operators/workers
Allowance must be made for space between adjacent equipment/machines for movement
of the worker, work-in-process, maintenance personnel etc.
