Have you ever wondered how Chocolate sandwich biscuits are made? What are the ingredients used, the processes used, and any problems that might occur? These questions are all answered in this article! Read on to discover how this sweet treat is made! Here are some of the main steps in the manufacturing process. Taking a closer look at each step will help you appreciate the quality of your biscuits! And don’t forget to sample a variety of them!
Processes involved in manufacturing of chocolate sandwich biscuits
The production process starts with sugar being separated from the air stream by a 915 mm diameter filter receiver. The sugar is then fed into a 500 kg capacity receiving hopper using a rotary valve controlled by a PLC. The sugar passes through a 915 mm diameter vibratory screen to separate the oversize material, which then feeds into the mixer. A small amount of liquid chocolate and palm oil are added to the chocolate cream blend. A PLC cycles the mixer and opens a discharge valve.
The biscuits are then further processed by being coated or sandwiched. This secondary process is also known as enrobing. The coating process involves dipping the biscuits in chocolate, water icing, marshmallows, or caramel toffee. Some biscuits also contain jam. Other biscuits are further processed before being packaged. Some sandwich biscuits are packaged directly from the oven and others are further processed before being packaged.
Ingredients used
Most manufacturers separate the primary and secondary processes in their factory. Storage techniques and facilities must be considered for the manufacturing process. As baked products with low moisture contents are very hygroscopic, it is important to store them in reusable containers that are well-sealed. These containers often don’t fit tightly and suffer from damage. Exposure to air in even a short time can lead to a reduction in crisp eating characteristics.
The type of cream used in sandwich biscuits depends on their eating characteristics and the processes involved. The cream should be firm at room temperature but still retain its shape when hewed. Creams with a high melting point should not squeeze out during the packaging process. Also, the cream should melt quickly upon being hewed. This will allow the sugars and other ingredients to release and form a thin layer between the shells.
Methods of production
The processes used for manufacturing Chocolate sandwich biscuits can vary in complexity. In a bakery, each cookie is created in an oven containing various chambers, known as zones. Each zone is an independent oven, and the number of zones can vary widely. The biscuits travel along mild steel continental wire mesh within the oven. They are then raised, puffed, and coloured in a series of steps within the oven. The process must end with the biscuits being golden brown or deep dark chocolate in colour.
In a chocolate sandwich biscuit factory, the process starts with the mixing process, where cocoa powders, palm oil, and sugar are added in sequential order to the mixer. This process is then automated and controlled by a PLC. A controller starts and stops the conveyors according to weight gain signals from the load cells. Then, the cooled chocolate is applied to the product in a second step, which is known as secondary processing.
Problems encountered
There are many problems that can be encountered while manufacturing Chocolate sandwich biscuit. Some of these issues are related to secondary processes. Typically, manufacturers will separate the primary process from the secondary process to ensure that they have sufficient time to make corrections and improve the quality of the product. Other problems include the removal of crumbs and soiling of the tins, which can be a huge pain. To solve this problem, manufacturers should ensure that their biscuits are made with appropriate size and design.
Cream filling: The quality of sandwich biscuits depends on the quality of the cream. The filling should be firm enough at ambient temperature to maintain the shape of the sandwich, but should also melt quickly in the mouth to prevent it from dislodging and falling off. This requires a controlled cooling process. Cooling air temperatures should not drop below the dew point, since condensation spoils the biscuit shell and the cream-cream interface.
