Think Thoughts 1

De-agglomerating batter mixes in food processing

Problems often occur during preparation of batter mixes because flour and other powdered ingredients tend to form lumpsor agglomerates as they are being mixed during production. A conventional mixer/agitator cannot break down these

agglomerates, resulting in a lumpy batter. If lumpy batter is used to enrobe products, it causes an unsatisfactory appearance

with misshapen or oversize products that do not fit properly into packaging. This can force production to a standstill.

Furthermore batter mix is generally recirculated from an enrobing system back to a holding vessel; lumps then have a

tendency to build up, reducing the flow of material and raising potential sanitation issues.

Question:How can we solve this problem?
