Tunnel Ovens - Industrial Ovens
There are several types of industrial ovens - also known as industrial tunnel ovens - being used in today’s large-scale industrial and commercial baked goods production facilities. Each type of oven has its own benefits and uses. In order to create a superior product that consumers will love, the proper oven needs to be to be used for the required job. Top quality food producers understand these facts, and use the correct ovens to produce outstanding products every day.
Many of our customers have proprietary baked items with specific criteria based on moisture content and protein content. Bakery Technology Enterprises, LLC, as a leader in oven baking technology, has 3 basic oven styles and and also builds custom hybrid ovens for specialty items.
Industrial Tunnel Oven Types
BTE Classic Oven:
The BTE Classic Oven is more than a typical recirculating baking oven, the classic has capability to bake many types of products because it includes as standard a dampner system that controls top and bottom heat direct and indirect, along with a balance adjustable plenum system for side to side even baking. The classic is #4 mill finish S.S. on the inner chamber and 14 GA aluminized metal. The classic is well insulated with industry leading thickness.
The classic can also be fitted with single or dual burners for each zone. The zone length can be from 30’ to 70’ and from 24” to 60” band or mesh width to accompany all types of baking needs. Many options are available to increase versatility.
The customer can also request Lonox burners if required to meet local codes.
BTE is also very knowledgeable concerning combustion systems and state of the art Lonox burners.
The classic can be fitted with standard controls with manual dampners or as an option PLC controls with Servo Motor driven dampers. Each zone is divided into 2 top and 2 bottom dampners to ensure continuous heat flows for better baking profiles.
The classic meets NFPA 86 codes and comes in pre-assembled units for ease of installation.
The Classic has been proven by bakery cookies, crackers, biscotti’s, pan backed protein bars, brownies, cakes, fig bars, and cheese sticks. Rotary molded products, wirecut products, extruders and sheeted products, etc. This oven is able to produce from high bake crackers to the softest cookies.
THE BTE Direct Fired Gas Oven:
The BTE Direct Fired gas oven has direct fired gas burners. The DFG ovens use ribbon burners, each having individual ignition and flame safety. The DFG ovens are primarily for cracker or sheeted style products. The BTE DFG oven has both separate top and bottom zones along with actual zoned linear sections. Each BTE DFG oven may also have pre-heat options depending on product and criteria for baking. The DFG ovens come in modular sections and include burner and safety covers.
BTE Classic Indirect Fired Oven:
The BTE Classic Indirect Fired Oven is designed with the recirculation fans and combustion chamber installed on top of each oven zone in the "penthouse" section. There is no flame directly in the product zone. Baking is achieved using a re-circulating air technique. The oven is heavily insulated for up to 650 °F operation.
The Bake Chambers are fabricated of heavy gauge Aluminized and each chamber is a unit-welded structure. Each chamber has Airflow Dispersion ductwork to ensure even baking. Telescoping support legs are field welded in place after final installation and alignment. The roof of the oven is reinforced to support personnel for maintenance and cleaning duties.
Inspection doors are provided in each zone of the oven. These doors allow access to the interior of the Oven for inspection of product.
Our Industrial Tunnel Oven Features:
The Ovens are shipped fully assembled in modules that will fit trucking.
More Efficient Heating
• The recirculation fan increases airflow thereby saving loss of heat energy which saves on gas consumption.
• Directional dampers improve the efficiency of the air distribution and makes the
oven easier to operate and improves control for a more consistent bake.
• Heat loss is reduced as well by using high-density insulation, high temperature rock wool batting in place of loose fill. The outer shell affords fewer opportunities for heat to escape and offers an easy to clean surface for easier maintenance. Both the exhaust fan and burner gas train are prewired. The re-circulating fan has been designed so replacement is inexpensive.
The oven is designed for faster, simpler installation. Modular in design, the BTE Classic model is installed in half the time it took for older models.
BAKING BAND CONVEYOR
The product is conveyed through the Oven Body on a 48” wide solid band, at controlled speeds of up to 50 FPM (Feet Per Minute). The band is driven & travels by drum ends on the Drive & Take-up. The band is driven by a variable frequency drive motor.
The recirculation blower returns the air and is controlled by a dampening system on the oven to allow change in airflow for different products. One (1) exhaust fan per zone is supplied to balance the system and to remove moisture-laden air as needed. This fan exhausts to the exterior
The fans are designed for high temperature continuous operation. Each have easy to service fixed speed, guarded belt.
Each Oven Zone is furnished with a LoNox packaged oven burner assembly. Each assembly includes all parts and safety devices necessary for control and safety supervision. The 40 to 1 firing turndown ratio provides wide process flexibility. Burner assemblies are pre-piped and pre-wired in easy to install modules. Each burner has a locally, mounted NEMA 4 junction box, combination blower air-inlet filter, air and gas mixing system, pilot flame system, spark ignition, flame detector and discharge sleeve. Each burner chamber has safety blow off panels. The gas train & safeties meet or exceed NFPA 86.
A. Temperature Controls
All zones of the oven are individually controlled for a temperature range of 100°F to 650 °F. Each is digitally operated, which receives a signal from a thermocouple mounted in the supply air stream. This digitally controls the fuel supply valve to maintain the design set point temperature.
B. Control Panel
One Control Panel is provided for the system. The Panel is powder coated mild steel. The components are Allen Bradley. The unit is pre-wired and free standing, complete with burner ignition and flame safety monitoring systems with diagnostic lights. The Panel is completely factory wired internally and tested prior to shipment, minimizing technical problems in the field.
BTE Pancake Griddle:
BTE Two Pass Pancake griddle oven is a DFG based two pass solid band griddle with capabilities of up to 50,000 pancakes per hour. The BTE pancake griddle has the unique ability to transfer the pancake after the bottom is baked to an upper shorted DFG griddle to finish the top back. This is done through a PLC controlled lift wrap conveyor that is perfectly timed to not slide or change the pancake or even French crape profile.
BTE Hybrid Ovens:
BTE can also build hybrid ovens that include DFG Burners and indirect type burners and zones. We also can include steam sections and floor drains with Stainless Steel applications.
