Enrobe

Enrobe is a term used in various industries, particularly in confectionery and pharmaceutical manufacturing, to describe the process of coating a product with a layer of another substance. This technique is commonly used to enhance the appearance, taste, and shelf life of the product.

Confectionery

In the confectionery industry, enrobing is a crucial step in the production of many types of chocolate and candy. The process involves covering a center, such as a biscuit, fruit, or nut, with a layer of chocolate or another coating material. This can be done manually or with the help of an enrobing machine.

Process

The enrobing process typically involves the following steps:

1. Preparation: The centers to be enrobed are prepared and placed on a conveyor belt.
2. Coating: The centers pass through a curtain of melted coating material, such as chocolate.
3. Cooling: The coated centers are then cooled to allow the coating to set and harden.

Pharmaceuticals

In the pharmaceutical industry, enrobing is used to coat tablets and capsules with a protective layer. This coating can serve multiple purposes, including masking the taste of the medication, protecting the active ingredients from environmental factors, and controlling the release of the medication in the body.

Types of Coatings

Common types of coatings used in the pharmaceutical industry include:

• Sugar Coating: A traditional method that involves coating the tablet with a layer of sugar.
• Film Coating: A more modern technique that uses a thin polymer-based film to coat the tablet.
• Enteric Coating: A specialized coating that prevents the tablet from dissolving in the acidic environment of the stomach, allowing it to dissolve in the more neutral environment of the intestines.
