Need help with Tray cleaning and Sugar spraying on biscuits

Hi,

We are a traditional bakery SME out of India. We manufacture Osmania Biscuits with a wood-fired oven. We don't use any nonstick trays. We are currently facing a residue problem with the biscuit and tray.

We manufacture Osmania Biscuit/ Butter Biscuit. So we currently spray sugar water to the dough post cutting. Excess sugar water is removed. We want to remove this sugar water thing from the whole production line. But we don't have an alternate solution. The biscuits top and sides crumble while packing. This sugar spray helps in decreasing this effect. Apart from this, trays have this sugar residue at the edges and edge biscuits are burnt at the bottom.

So how do we clean the trays or do we have to get new trays everytime?

How to remove the sugar spraying from production line.

P.s: We don't use any emulsifiers or any additional agents. only essence and normal raw material.

Thanks In Advance :)
