How Does An Enrobing Machine Operate?

Here is how this machine operates:

Tempering

Here, you will place the enrobing materials, such as chocolate, on the tempering system.

It will melt the chocolate and ensure it is in a smooth and consistent form.

Also, tempering systems connect to the enrober to facilitate the supply of liquid chocolate to the enrobing stage.

Tempering machines can come with enrobing lines, which you can also purchase separately.

Placing The Product On Wire Racks

This system will carry the products via the prebottomer that evenly coats the lower part of the products.

The prebottomer is a component that you can buy separately and connect to the enrobing machine.

Transportation To Enrober

Wire racks will transport the products to the enrober as it passes via a preliminary cooling conveyor.

The cooling conveyor assists in the solidification of the chocolate from the prebottomer.

Coating Pumps

Conveyors transport the products towards coating pumps that cover the products via a continuous chocolate waterfall.

The coating pumps will enrobe products.

Drainage Of Excess Chocolate

The chocolate that fails to coat the product moves via return systems.

These systems will recycle them back to the tempering system.

Vibrating Table

These parts will cause the wire racks to vibrate after the products pass the coating pumps.

This vibration enhances the even distribution of chocolate on the lower part of the products.

Blowers will also ensure the chocolate does not form a pool on the upper portion of the products.

  • Elimination of chocolate tails

High-quality enrobing machines have tail cutters that remove the chocolate tail coming from the enrober.

  • Transfer to wax papers

After enrobing the products, they move to wax paper to facilitate easy removal after the cooling process.

  • Toppings

This feature is optional, and they operate by sprinkling toppers on the products.

  • Cooling tunnel

The enrobed products move to the cooling tunnel, where it leaves for packaging after it solidifies.

This part is long and has insulations to ensure a constant and low temperature.

The reason is that it has a small footprint and fewer components.

How Do You Increase The Efficiency Of An Enrobing Machine?

Maintaining and cleaning the enrobing machine ensures it performs optimally and increases its durability.

Conduct frequent inspections to ensure all parts are in good working condition.

Replace faulty or broken parts with genuine parts that the manufacture recommends.

Clean the machine after every use to minimize the buildup of dirt and debris.

Repair all broken electrical cords to eliminate changes of fires and electrocution.

Lubricate all moving parts to minimize the rate of tear and wear.

Ensure you set the enrobing temperature that matches the materials to enhance the enrobing process.

Tighten all loose ends and ensure they are in the correct position.

Use the suitable raw material, in terms of quantity and size, in the machine to ensure the operation runs smoothly.

What Safety Precautions Should You Look Out For When Operating An Enrobing Machine?

These include:

Protective Gear

All operators should wear the necessary protective gear to eliminate any damage that may happen during operation.

These protective gears should protect you against bodily harm such as a burn.

Hygiene

Since you are handling products for human consumption, the hygiene of the operators should be a priority.

Lay down steps that each operator should adhere to before operating an enrobing machine.

For instance, those who have long hair should cover them.

Fire Safety

To protect you and the operators from fire hazards, you should have a set fire safety procedure.

For instance, you can install fire alarms that go off in cases where there is a fire.

Also, set fire assembly points where you can account for all operators.

Professionals

Hire professionals to ensure your enrobing machines operate correctly.

This operator should have knowledge and skills on how the enrobing machine operates.

Also, when maintaining the machine, hire professionals who understand the device entirely.

What Is The Ideal Temperature When Enrobing?

Always ensure the centers that enter the enrober have a temperature between 21°C to 24°C.

When the centers are warmer, blooming may occur as the residual heat will increase the temperature of the enrobing medium.

Also, cold temperatures will cause blooming and cracking of the coat as the center expands as it warms.

After enrobing, to eliminate blooming, gradually change the temperature in the cooling tunnel.

The coating and filling should cool to approximately 18°C to achieve trouble-free packing.

What Should You Consider When Installing An Enrobing Machine?

When installing, ensure the following:

Space

Ensure the available space is enough to fit the machine with enough room for maintenance and operation.

Power Requirement

Make sure the power source provides the correct voltage to run the machine

How Does An Enrobing Machine Compare To A Wrapping Machine?

The difference lies in the state of the product you are processing.

An enrobing machine uses an enrobing medium that is in a liquid state to cover products.

Enrobing machines will enhance the appeal of a product by improving taste.

Also, you will use enrobing machines before wrapping or packing the product.

A wrapping machine will process products that are in a semi-solid state.

Wrapping machines improve the appeal of products by covering them with film material.

A wrapping machine is at the ends of the production line, and you will use it after you fully process the products.

How Do Enrobing And Molding Compare?

Here is how these two compare:

Enrobing

This process involves making the center of the product first, then coating it with a thin layer of enrobing material, i.e., chocolate.

The product passes under a curtain of chocolate to create a thin and crisp layer.

Some benefits of enrobing include:

  1. It allows you to create a thin crisp layer on the product
  2. An enrobing machine will enable you to achieve a quick and efficient enrobing process
  3. Also, you can decorate the product in several ways, such as forming fork marks, etc.

Molding

Here, you process the product by using a mold such as a firm plastic.

You will fill the mold with, for instance, chocolate, then turn it upside down to eliminate excess chocolate.

The remaining chocolate within the mold creates a cavity that you can fill with another product.

Some benefits of molding include:

  1. It forms a thin and crisp shell that encapsulates various centers which have different textures and viscosity.
  2. Also, you can mold different shapes depending on the design of the mold.
  3. Besides, skillful chocolatiers can use cocoa butter of different colors to form striking chocolates resembling glass marbles,
  4. You can make custom molds and imprint your company logo so that it shows on the final product.

What Is The Importance Of Physico-Chemical Properties Of The Enrobed products?

There are two reasons why the Physico-chemical properties of enrobed products are vital.

Firstly, incorrect crystallization or flow properties result in the product having poor quality.

This effect will make you sell the product cheaply or rework the product.

Secondly, the sensory attributes are essential to the client’s satisfaction.

When a product is not glossy, or the fat has bloomed, a customer may not purchase it.
