GEA can configure ovens to meet any requirement offering a full range of ovens, that includes direct gas-fired (DGF), radiating – cyclotherm (IC), indirect convection (CVI) and hybrid ovens (HYB).
Most products have specific baking requirements, and require different heating methods, temperature, humidity and residence time in the oven, which can all affect the final product quality and consistency. We design, configure and install tunnel ovens for different types of baked products, with working widths of up to 2000 mm for biscuits, cookies, crackers and snacks.
Our modular design enables us to customize the heating system for each zone, as well as varying the zone length, to meet the production requirements. In response to industry needs, GEA also offers a comprehensive range of pilot ovens, so that our customers can test their baking processes in a small scale, or to manufacture smaller batches of new recipes and products for field tests and trials.
GEA ovens are designed using state-of-the-art 3D modeling and simulators, so that we can test and evaluate new solutions using computer software to make sure that every detail is optimized. GEA ovens are manufactured to meet the strictest safety and hygiene standards, using high quality materials and components. Our customers can therefore be confident of reliable, uniform baking for their products.
GEA supplies a variety of conveyor systems to match the product type and baking profile. We can tailor the conveyor system to suit your product and production requirements.
GEA has always focused on developing sustainable equipment and solutions. This means that we focus on energy use, waste and emissions to enable our customers to reduce operating cost and meet their environmental and sustainability objectives. Our ovens can be equipped with optional energy recovery systems that cut energy consumption by up to 30% and which can be used to reuse excess heat in other areas of the plant. The energy saved will depend on factors such as the oven heating system, type of product and baking profile. Oven insulation using high-density rock wool further ensures that minimal heat is lost through the oven walls, while an automatically controlled extraction damper helps to save energy and reduces emissions to the atmosphere.
Our indirect convection ovens feature an enhanced convection heating system to achieve high product quality and efficiency. This type of oven is used to bake different types of products such as soft and hard biscuits, cookies, cakes and pies.
The baking chamber of the indirect convection oven is fitted with a plenum duct positioned on the top and bottom of the baking conveyor and the hot air is blown into the air distribution system by a fan.
Hot air is heated as it passes through a dedicated heat exchange system where it is then gently blown into the baking chamber through specially designed nozzles.
Heat transfer is predominantly achieved by convection, which ensures even baking of the product. The combustion fumes are circulated in a closed system so the product never comes into direct contact with them during baking, allowing the use of gas or oil based fuels for heating.
The indirect convection oven is often used in the final part of hybrid ovens to improve the humidity extraction and achieve a better product color. Hot air from the baking chamber is drawn back to the fan to be re-circulated through the circuit. Each heating zone has a single burner and an automatic steam extraction system that controls the humidity of the air to achieve maximum product shelf life.
