How to remove air bubbles in batter mix when mixing?

hi All,
we are running trials of wheat batter that us to make pastry sheets on hot moving drums.
actually when we bake on hot plates and when we bake the air bubbles appear during baking that making it unacceptable as per our quality standard. this is new product for us . anybody help me out , what to do with the batter during mixing to minimize or reduced to zero level of fine air bubbles .

the main ingredients of the batter
fine wheat flour
salt
water
lecithin

Dear Sir,

You can deaerate the batter before baking to remove any entrapped air bubbles. Alternatively you reduce the mixing speed of the batter mixer and try.
