Baker Perkins TruBake biscuit baking oven

The Baker Perkins TruBake biscuit baking oven is a direct convection oven, suitable for baking biscuits, cookies and crackers.

The burner and fan module creates a laminar flow of air over the full width of the burner. This continues into the ducts and plenums and leads to a stable and even distribution of convection air over the full width and length of the oven band.

A high-capacity fan ensures that the volume and velocity of air is maintained. In conjunction with a burner turndown ratio of up to 20:1, this creates a wide operating envelope, making the oven suitable for products from soft brownies to crackers.

Hygiene is enhanced by stainless steel covers and improved access for cleaning. Clean-out ports have been added to top and bottom plenums enabling dust and debris to be removed. The frame is stainless steel and no paint is used inside the oven.

The oven is modular, and zone lengths can be varied to achieve the baking conditions required. A choice of process options is available, including the option of a hybrid oven, with an initial direct gas-fired section to achieve high levels of radiant heat in the early stages of baking, followed by direct convection to dry and colour the product. The oven itself can be specified in either direct convection or radiant mode.

The extraction system has been optimised to minimise energy consumption. Air that has given up its heat to the product is drawn back to the burner module for reheating by the circulation fan. A proportion of this air is vented to atmosphere to remove product moisture and maintain a constant humidity level in the baking chamber. No additional extraction fans are required, contributing further to energy efficiency.
