We have seen Grandpas who love to savour dipped light biscuits in their tea and younger generation who derive immense pleasure from licking the cream of the biscuits. Biscuits are something that each likes to have in its own way. Then there are wafers which we love as on our ice creams, or as an alternative to chocolate bars. Small, as they are mostly, we hardly realise the long processes that are involved in the Biscuit & Wafer making plants to produce the delicacies. We hardly bother about the technicalities, lost in their tastes.
A Biscuit is flour- based, baked product which is generally crispy. In some countries cookies and biscuits are treated synonymously, but they are mostly different, crispiness being the main dividing factor. A wafer, on the other hand is a thin, crisp, flat cracker. It has, what looks like a lesser distinctive waffle-like,cellular surface. Wafers are also used as decorates, as well as, in middle layers of wafer Chocolate bars, etc.
The common steps that are seen in biscuits manufacturing plants are:
- Kneading of dough, which might be a one stage or multiple stage process, depending on the type of biscuits that are to be manufactured. This requires a Dough-Mixer machine.
- Fermentation process of the Yeast mixed dough.
- The shaping process in which the dough is placed on the conveyor connected Hopper (machine). It is flattened, compressed under series of rollers, conditioned to toughen.
- Coating with toppings of cream, etc.
- Cutting through a Rotary Cutter to get the desired shape.
- Baking the raw biscuits in oven at a prefixed temperature for a fixed duration.
- Cooling the hot biscuits.
- The quality testing in laboratories.
- Packaging of the end product.
The equipment required to prepare wafers are special. They are baked using batter, between pairs of metal plates or wafer roll baking machines, which are heated. After coming out as flat sheets, they are sandwiched with cream or moulded in flavours.
This is a brief introduction to the entire process inside the biscuits and wafer making plants. What matters most is the feeling of having it.We all have our own biscuit memories from childhood.Rectangular or round, digestive or rich, creamy or plain, extra sweet or somewhat salty, these bakery items are found in jars of every kitchen.
