APPLICATION

Up to the blackboard!

On how to tackle a coating project ?

Wanting to develop or improve the coating of a food product ? Or having a problem which can be solved by coating ? Here is how to handle an application.

First, write the brief, and define the purpose of the coating :  aspect, texture, taste, flavour, preservation, functionality … ?

BASE

Core products

What is the core center to coat ? Composition, size, shape, texture, moisture, bulk density …

RECIPE

Ingredients

Are they specific ingredients to apply or are you looking for the appropriate ingredients ?

PROCESS

How does it work?

Upstream

Where does the core product from ? How is it shaped ?

Coating process

Is there an existing process or are looking for a technical solution ?

Downstream

Most probably a finishing step is required to stabilize and give its characteristics to the coated product

PROCESS

Coating system

The challenge is to reproduce at a larger scale what has been done manually in hte kitchen or at  the benchscale. What operating principle to choose : band, pan, tumbler with dipping, dribbling, dispersing, spraying …

PROCESS

Coating system

If existing, what is the coating system characteristics ? Type, capacity, make … Any picture, documentation, reference of it ? Where to source it ?

PRODUCT EVALUATION

How do you measure your success?

Key quality features

Specify the criteria to evaluate the quality of the product i.e. performance of the process

A few examples hereafter

Visual

Visual aspect, shape, texture, colour, homogeneity, coverage, integrity (absence of breakage, dent)

Taste

Texture, thickness, flavour …

Function

Does the coating fulflls the expected function i.e. mechanical strength, barrier, shelf-life …

Key quality parameters

What are the process parameters which drives the result and influence the quality features ?

Fixed parameters

System working principle, design, geometry, volume … Is it batch or continuous ?

Variable parameters

Essentially respective dosage rate, speed, temperature, pressure, air (°C, % RH), ingredient characteristics (viscosity, granulometry) …

Operation

Frequent product change, working 1-3 shifts, cleaning requirements …
