Den Boer Impingement Tunnel Oven

AMF Den Boer Multibake I 

The Multibake® I Tunnel Oven by AMF Den Boer is an indirectly heated oven, employing hot air transported at high speeds to both the upper and lower side of the product. This is accomplished using an industrial burner coupled with a stainless steel heat exchanger. Also known as a conventional tunnel oven, the Multibake I leverages impingement heating technology to indirectly heat the oven by means of impinging jets/nozzles.

This oven is also available with a Dual Fuel Option, featuring independent heating systems within the same oven.

Key benefits

  • Dependable and adjustable heat transfer to bottom and top of product
  • Optional moisture monitoring and steam injection
  • Variable air speed towards the product
  • Excellent evenness and conformity of heat transfer, resulting in consistent product quality while eliminating vulnerability for production gaps
  • Flexible height adjustment of the top plenum. The baking chamber height is dependent on the product height while baking. For example, with cake production, a low plenum height of 100 mm is required in the first stage of baking and a greater height of 200 mm is needed in the end stage..

Impingement Tunnel Oven Equipment Features

The heating of the Multibake® I is entirely indirect, using a certain number of heating (burner) modules at the top of the baking tunnel. Each heating module consists of an industrial burner and a specially designed stainless steel heat exchanger. The burner and heat exchanger are combined in a compact unit. The heated air for baking (process air) is transported equally over the heat exchanger by means of one fan. The fan is equipped with a corten steel blower.

Independent Zone Control

ADVANCED AIR CIRCULATION

The circulation fan takes air out of the baking tunnel. The air is subsequently fed through the heat exchanger and along the heating chamber. The heated air arrives in the air division chambers, called plenums. The plenums are located underneath and above the transport conveyor. The heated air is blown regularly and directly on to the product. This means that the heat is transferred directly and quickly to the product (the “impingement” principle).

The air speed can be set in the baking tunnel for each zone by means of a frequency controller. The plenums are made entirely from corten steel and have a special nozzle pattern, adapted to the desired output in the various baking zones. Plenums will have fixed heights (adjustable height is optional).

Optimal for a wide variety of products, including:

  • Cakes
  • Pies
  • Artisanal Bread
  • Rolls
  • Pizza
  • Flatbreads
  • Pastries
  • Croissants
  • Cookies
  • Cereals
