While induction heating in industrial applications has been in widespread use for many years, particularly within the metal processing industries, there is now increasing interest in this versatile technology for other heating applications. Induction heating can be particularly useful for products which might be sensitive to excess heating, thereby creating a spoiled product, or in applications where heat is required to be applied in difficult geometries. C-Tech Innovation has extensive design and build capabilities for this kind of specialist induction heating equipment.
Food processing using ohmic heating reduces the need for preservatives and results in superior taste and texture compared to other thermal treatment methods such as jacketed vessels, heat exchanges or steam injection. The Qulom OBA-26 is an ideal tool for R&D and recipe development at temperatures up to 100ºC. For higher temperatures we offer a prerssurised batch unit the Qulom OBP-26, capable of operating at up to 150ºC. Read More
C-Tech Innovation undertook a Carbon Trust funded project to quantify the potential energy savings available if microwave chemistry could be scaled up to plant scale.
The use of volumetric microwave heating to augment conventional heating in gas and electric kilns significantly reduces issues due to temperature gradients leading to improved product quality and kiln operation. Calcination, sintering and drying of materials can be achieved with equal or improved product quality and significantly reduced energy costs. Read More
Conventional cooking of foods relies on conduction from hot surfaces into the food. This can limit the rate of cooking, especially in products with large solid particles. By using the food’s own electrical resistance to generate the heat using C-Tech Innovation’s Ohmic Heaters, food can be heated evenly from within. The result is greatly increased cooking rates whilst maintaining the highest product quality. Read More
Quality is the major driving force in the food and drink industry, premium products can attract a prime market. Heating of food during the manufacturing process can radically alter the characteristics of the finished products. Quality and taste can be significantly affected if the processing parameters are not closely controlled.
