Sidwell, known for his show Britain’s Best Bakery, will be carrying out cooking demonstrations throughout the day.
The event will also allow Unox UK to launch its new stone deck oven.
The company said the oven ensured restaurants could “expand their menu without sacrificing quality”.
The unit is best for baking products that require direct base heat. It also claims to be more economic by running on 3kW, and features programmable controls, humidity injection, LED chamber lighting and a safety cool-touch drop-down door.
