Tunnel Rack Oven System

The Dijko Tunnel Rack Oven System is unique. It has been specially designed for use in bakeries and confectioneries where products are baked on trays or in tins. The system is suitable for producing a wide range of products including the many varieties of bread (buns, rolls and loaves), pizzas, pies, biscuits and full range of cakes (cupcakes, muffins, sheet cakes), cookies and pastries. Mixed production can be accommodated within the full system.

The Tunnel Rack Oven System is of modular construction and can be used whenever baking temperatures up to 300 °C are needed. Appropriate modules can be supplied for proofing, baking, (vacuum)cooling, freezing and automatic tray loading and unloading. Furthermore, additions can be made to incorporate additional product handling, such as eggwashing, water cutting, or lidding of trays (typically all done after proofing).

Typical production capacities for the Tunnel Rack Oven System can range anywhere from 250 kg/hour to 5.000+ kg/hour, but are highly dependent on the products being produced on the system.

Rack and Tray Configuration

The Tunnel Rack Oven System uses trays and racks to transport your products through the system. We can accommodate a wide variety of tray sizes, ranging anywhere from 460×660 mm (standard 18″×26″), to massive trays of 920×1500 mm. A few typical tray sizes that are commonly used in our system include:

  • 800×400/600/800 mm
  • 900×600/900 mm

We are always willing to look into the possibilities of matching our system to your existing trays and equipment, eliminating the need to renew them.

The trays are placed inside special racks, that form an integral part of the Tunnel Rack Oven System. Each rack is exactly one module long, and forms the front, back and bottom of each module. Racks are placed back to front, sealing off all modules. Each rack is able to hold between one and four columns of baking trays, depending on the tray size. 

The amount of baking levels inside the Tunnel Rack Oven System depends solely on your finished product and tray height combined. A typical amount for the number of baking levels ranges between 8 and 16, but systems have been designed for as many as 40 levels. This ensures a minimal use of floor space, often as little as 2O% of that required for a conventional traveling oven of similar output. This saves valuable space, which is often a major concern for businesses who are expanding their production.

System Overview

The Dijko Tunnel Rack Oven System can comprise of multiple modules and sections, which will be described below.

01. Loading Tower
Loading of the trays into the racks can be done using an automating loading system. This system will accumulate the required amount of trays (equal to the amount of baking levels), after which they will be pushed into an empty rack.

The loading tower is able to receive trays at all possible heights, even from other floor levels.

02. U-Transport
The U-Transport makes the racks move to an alternative lane, and is typically used when limited length is available, or when a fully automated system is in place.

Depending on the requirements, the Tunnel Rack Oven System is equipped with zero U-Transport modules (semi-automatic system with infeed and outfeed of racks at opposite sides), one U-Transport (semi-automatic system with infeed and outfeed of racks at same side) or with two U-Transports (fully automatic system). In the fully automatic system, no manual rack handling is required during operation, and the racks remain inside the system.

The U-transport is fully made from stainless steel, and has two roll-up access doors that allow for the racks to be taken out of the system during maintenance and/or cleaning.
