The conveyor belts can be very helpful, if you plan ahead correctly. There are three conveyor belts on top of one another in the middle of the board so ingredients can get stuck there.
You need to keep the ingredients on the conveyor belts until they are in one of the three columns with extraction points. You need to set up your moves to make timely matches to bring the ingredients down when they are in the right position.
As in every ingredients level, striped vertical candies are very effective. If you have an ingredient in one of the three middle columns along with a vertical candy in that column, you can activate it and collect the ingredient immediately.
You can also use the conveyor belts to position vertical striped candies in the correct columns as well. Combining a wrapped candy with a striped candy is also a good tactic because it expands the width of the vertical column clearing.
