  • Many sandwiching machines are automatic, thus reducing your labor needs and hence your production costs.
  • Conducting changeovers when using the sandwiching machine is simpler, requiring very few protocols.

What are the Methods of Cream Application when Using a Sandwiching Machine?

The sandwiching machine’s methods of the cream application describe how you attach the cream filling used between the biscuits. There are several methods you can use to apply the cream, including:

       i.          Stenciling Method

The stenciling method has been in existence for a long time and prevalent with manual and automatic machines. With this method, you stencil the cream on a biscuit surface before adding another biscuit over it.

You use a flat metal piece with a depth similar to the cream’s desired thickness to make a stencil. You cut this metal piece in the desired shape of the cream and considering the size of the biscuit.

You attach the bottom biscuit below the stencil under the cut-out design before filling it out and leveling. Thereafter, you transfer the biscuit with cream to another section where you add the top biscuit.

      ii.          Using Depositors with Multiple Nozzles

You find two constructions of these depositors with multiple nozzles, with one made mobile and the other secured permanently.

The mobile depositor head can move vertically and laterally, following the biscuits in their path while applying the cream.

The depositor’s head moves downwards towards the biscuit while simultaneously releasing a fluid cream onto a biscuit.

The cream stream breaks off as you raise the nozzle, and the filled biscuit moves along the line.

    iii.          Use of Extruders and Wire Cutters

Here, a hopper deposits cream on the biscuit via a nozzle in the desired shape. You use the wire cutter to cut off the cream stream from the nozzle.

The extruder and cutter work in continuity such that an extrusive operation immediately precedes a cutting operation.

The biscuits move in a rotation where another moves in its place as soon as a biscuit fills up.

After the creaming station, the biscuit moves to another station where a pin pushes the top biscuit over the cream.

Subsequently, a wedge or roller presses the two biscuit pieces together to form a sandwich.

  • You can adjust the conveyor chains’ position such that their location is far from that of the depositors.
  • You can increase the breadth of the machine to accommodate more rows.
  • You can also alternate the creaming process such that you deposit cream on one biscuit and skip the next.
  • You achieve high production speeds with this method with reduced complexities in terms of cooling and packaging.
  • Using an extruder and wire cutter allows you to adjust the weight of the cream.
  • You find it difficult to produce biscuits with irregular shapes and forms using this approach on a sandwiching machine.

How do you Mix and Handle Creams in a Sandwiching Machine?

There are two ways you can mix the cream with a sandwiching machine including:

·       Batch System

Plasticized fat is the basis of a batch system and typically begins with a chunk or an impelled amount.

When handling plasticized fat in bulk with sharp gradients of melting, you require specialized control processes.

Adding sucrose and additional ingredients causes the temperature to reduce compared to that of the cream mix.

You follow the addition of ingredients by blending the products using a whipping action.

You whip the cream ingredients until you acquire a desirable consistency with the appropriate density and temperature.

You can alter the batch processing by selecting fat and the type of machine you employ for creaming purposes.

·       Continuous Mixing Systems

A continuous system typically begins with fat that is entirely melted, giving it a warm feel. Additionally, the mixer regulates aeration in the cream and channels it to the creaming unit via a pumping mechanism.

You attain adequate fat temperate by employing a heat exchanger to initiate a steady cooling process.

Using icing sugar in the desired quantities poses a problem when done continuously and basing on weight rather than volume.

You need to maintain a steady speed of the continuous mixer during operation. Also, ensure the delivery path of the cream mix is circular with take-offs at respective creaming stations.

Why is the Cooling of a Creamed Biscuit in a Sandwiching Machine Important?

When making filled sandwiches, you contain them in a cooling channel to eliminate excess heat after the sandwiching process.

Cooling also allows the cream filling to harden before you package the biscuits or turn them over for additional processing.

When you don’t cool sandwiches, you can expect the sandwich’s deformation as it is held during packaging or transportation.

Avoiding cooling causes the biscuits to be malleable, making them succumb to the pressure applied during sealing.

It is important to cool your biscuit sandwiches to apply their physical structure and extend their shelf life.

You need to ensure the cooling process is optimal such that when exposed to high temperatures later, the cream remains firm.

What Causes the Splitting of Creamed Sandwiches made by the Sandwiching Machine?

Splitting of a sandwich occurs when the cookies disintegrate while in storage. You can attribute splitting to several reasons as its cause is not apparent.

Some of the common reasons for splitting include:

  • Breakdown of the molecular forces holding the biscuit together during the sandwiching process.
  • The hygroscopic nature of biscuits when exposed to the atmospheric moisture content.
  • Impediment of the movement of the fat crystals weakening attachment.

What Biscuit Shapes can you Make Using the Sandwiching Machine?

You can achieve the following biscuit shapes when using the sandwiching machine including:

  • Biscuits in conventional shapes such as round biscuits, square biscuits, and rectangular biscuits.
  • Biscuits in non-conventional shape such as jig-shaped biscuits, concave biscuits, and those resembling 2D animated characters.

Furthermore, when using a sandwiching machine, you can present your biscuit such that they take varied forms, including:

  • Mini sandwiches
  • Two-layer cream fillings
  • Biscuit sandwiches with three tiers, and
  • Customized shapes
