## Abstract

A process for preparing a dehydrated carbohydrate-containing nutritional product comprises preparing a liquid concentrate with a reduced carbohydrate content, spraying the liquid concentrate into a spray-drier and incorporating the remainder of the carbohydrate content into the nutritional product by blowing solid carbohydrate particles into the spray dryer and removing the carbohydrate-containing nutritional product from the spray-drier. The process substantially reduces the problem of fouling of the spray dryer

## Claims

### Claim 1

A process for preparing a dehydrated carbohydrate-containing nutritional product, comprising preparing a liquid concentrate with a reduced carbohydrate content, spraying the liquid concentrate into a spray-drier and incorporating a remainder of the carbohydrate content into a nutritional product by blowing solid carbohydrate particles into the spray-dryer and removing the carbohydrate-containing nutritional product from the spray-drier.

### Claim 2 (depends on 1)

A process as claimed in claim 1, wherein not more than 40% of the carbohydrate content of the nutritional product is blown into the spray dryer.

### Claim 3 (depends on 1)

A process as claimed in claim 1, wherein from 20 to 30% of the carbohydrate content of the nutritional product is blown into the spray dryer.

### Claim 4 (depends on 1)

A process as claimed in claim 1 wherein the entire content of a specific carbohydrate in the nutritional product is blown into the spray dryer.

### Claim 5 (depends on 4)

A process as claimed in claim 4, wherein the specific carbohydrate is pre-gelatinised starch.

### Claim 6 (depends on 1)

A process as claimed in claim 1 wherein the carbohydrate powder is blown into the spray dryer in the zone of turbulence of the spray dryer.

### Claim 7 (depends on 1)

A process as claimed in claim 1 wherein the spray dryer is equipped with a blow back apparatus and the carbohydrate particles are introduced into the spray dryer by means of the blow back apparatus.

### Claim 8 (depends on 1)

A process as claimed in claim 1 wherein at least one component selected from the group consisting of vitamins and minerals are incorporated in the nutritional product by being blown into the spray dryer with the carbohydrate particles.

### Claim 9 (depends on 1)

A process as claimed in claim 1 wherein the solids content of the liquid concentrate is at least 50%.
