The meal cooler is a cooler that is designed to operate with
a fluidized bed. It is used when product beds of meal type
products are so dense that they will not let air pass through
unless the bed is fluidized.
The use of the fluidization principle means that almost every
component needs to be changed compared to a normal counterflow
cooler.
Inlet valve, hood, product distributor, bin walls, discharge
systems, product sensors, hopper, air fan, ducting, control
system; all need to be customized to make a counterflow cooler
suitable for meal cooling. In standard execution, the meal
cooler consists of two cooling decks above each other.
Cooler fire safety
A fire valve in the hood cuts off the supply of fresh air
in case temperature in the cooler reaches a pre-set limit
(standard).
Operator safety
Sensors and control systems ensure that no access to the
inside of the equipment is possible without first shutting
down all moving parts (standard).
Bevelled corners
Bevelled corners in the hopper ensure that no product or
fines build up in this vulnerable place (standard).
Cooler insulation
Insulation of the hood and bin walls leads to a significant
reduction in the risk of internal condensation (optional).
Air flow control
With Automatic
Air Flow Control Valves air volume
can be accurately controlled. There is automatic stabilisation
of air volume, irrespective of the bed depth and the required
air volume can be recipe dependent. No more blow holes during
start up or emptying, no more excessive amounts of fines
flying into the cyclone (optional).
