-. Antti-teollisuussupplies as standard a grainpocketfordryers with more than threetop
sectionsandadiagonal(conical) air inlet. The grain pocket shall be installed in the
connectingpipebetween the dryer and theheater.As necessary the grain pocketmustbe
emptied of gathered grains. So its filling grade must be observed. See illustration
“Installation of the grain pocket to the air piping” for the correct installation practise.
WARNING! Foreign particles inside the heater are a fire hazard!
Install the grain pocket to the horizontal part of the
air pipe, where it operates efficiently, See
illustration
Lift the part close to the pipe and attach it properly
using the ties. Working inside the part, draw a
cutting line using a felt-tip pen, take away the part
and use a handheld profiling machine or plate
shears for cutting the opening.
Lift the part back in place and tie it to the pipe
using the ties. Attach the part to the pipe with self-
tapping screws or rivets. Finish with sealing
mastic. Close the outlet sleeve of the pipe of the
grain pocket with a plug and, as required, secure
that it stays in position using self-tapping screws
