Typical Applications

1. Pan LubricationBaked dough tends to scorch and can stick to the pan walls. The application of a release agent eases unmoulding. Spraying this agent ensures an accurate and even distribution, saving ingredients and increasing pan life by 2-4 fold.

2. Trough LubricationAfter mixing the flour with the water and the ingredients, the resulting dough is transferred to a forming system. Being sticky, it tends to adhere to the funnels and resist transfer. A fine film of oil can be sprayed onto the funnel wall to aid transfer of the dough.

3. PreservationThe shelf life of packed pastries is limited by their high water content which allows moulds to grow. A controlled dose of diluted alcohol is an efficient preservative. Spaying ensures a safe, accurate and traceable application, increasing shelf life by up to 5 weeks.

Oil & Flavour

4. Oil & FlavourOil is applied on savoury biscuits to enhance the flavour, stick salt and prevent cracking. An excess of oil causes smearing, too little oil leaves a bland biscuit taste. Careful and accurate oil distribution over a wide belt conveyor is achieved with Pulsajet manifolds.

5. Gel & SyrupThick sugar and honey syrups display high viscosities at room temperature. A fully jacketed spray system, heated from reservoir to nozzles ensures an even and accurate application.

6. DecorationChocolate is used as a decoration on cakes. Designs can be traced by light-weight nozzle assemblies supported by a robot arm. Image analysis even allows decoration on cakes placed randomly on the conveyor.

7. Chocolate EnrobingBakers may want to coat the surface of large cakes without coating the sides. A temperature-controlled spray system ensures the application of a fine layer with limited overspray.

8. Barrier FatSnack items may comprise layers of different moisture, thus affecting the shelf life of the product. A fat barrier is applied to prevent undesired migration. To deposit a fine film, a spray system combines temperature control and accurate dosing.

9. Bread ScoringBread loaves are cut to ease the release of gases during cooking. It is also a common feature for bread. The manual operation has risks and limitations. Scoring can be achieved by a jet spray ensuring a safer operation and increasing volumes to several 1,000s per hour.

10. Egg Wash & GlazesRolls and pastries are usually covered with a glaze to enhance its appeal after baking. A dedicated spray system ensures an even application without excess, giving the right colour and shine. A return on investment is obtained after 1 year or less by saving on ingredient and cleaning.

11. Glue Application for SeedsHaving particles to adhere on top of dough before baking requires slightly moistening the surface. Controlled spraying of water or a light glue solution ensures the right tack to fix seeds, cereal grains…

12. Humidification Atmosphere needs to be adjusted in proofing rooms or baking ovens. Specific instrumented spray systems ensure the dispersion of a fine mist and the accurate control of the humidity. To ensure palatability of baked items, it may be necessary to adjust its moisture after baking and prior to packing, while not exceeding a given water activity to prevent mould growth. Again careful spraying ensures a even distribution and dosage.
