Continuous Oven Line: High-Capacity Food Processing
Custom configuration. Commissioned 2023–2025. Reference performance data available.
Continuous Oven
Square’s continuous oven’s hourly yield can be between 24,000 to 60,000 pieces of burger buns per hour. The working temperature is in a range of 195°C and 230°C, and the baking time is adjustable from 10 to 30 minutes. The oven can work together with our proofer, cooler, and freezer and form a complete bakery production line.
Our continuous oven is suitable for the automatic and mass production of bread, biscuits, laminated pastries, and the like.

Product Features
Why Choose Square's Continuous Oven
Explore the original product feature overview, including Security, Forming Bakery Processing Line, High Automation, and the key technical advantages behind this system.
Security
- Gas Detection: During production, real-time monitoring of gas concentration in the air ensures sufficient combustion. If levels exceed safety thresholds, the entire system halts operation, closing all valves while the exhaust system continues to function.
- Floating Structure: All top panels feature a floating structure, allowing them to lift in situations of increased internal pressure. Multiple pressure relief structures are integrated into the top for added safety.
Forming Bakery Processing Line
Our continuous oven seamlessly integrates with our proofer, cooler, and freezer to create a comprehensive bakery production line.
High Automation
Our continuous oven boasts advanced automation features, streamlining the baking process and minimizing manual intervention. From temperature control to timing adjustments, automation enhances efficiency and consistency.
Large Capacity And High Efficiency
With an hourly yield ranging from 24,000 to 60,000 pieces of burger buns, our continuous oven maximizes production capacity while ensuring high efficiency. Its adjustable baking time and temperature range contribute to efficient throughput and product quality.

Design Details
How each subsystem is engineered
Expand any section below for the engineering approach behind each critical subsystem — with links to detailed Technology pages.
Top/Bottom Heat Management
The defining feature of a continuous oven is independent top and bottom heat control per zone. This enables precise cooking profiles:
- Bread baking: Strong bottom heat in early zones for oven spring, balanced top/bottom in later zones for crust color
- Pizza: High bottom heat for crisp crust, moderate top heat for cheese melt and browning
- Cookies: Balanced heat with precise temperature control for even baking without edge burning
- Prepared meals: Bottom-dominant for conduction through tray, top heat for surface browning
Straight-Line vs. Spiral Oven Selection
Choose Continuous (Straight-Line) Oven when:
- Cook time < 20 minutes — straight tunnel is more cost-effective
- You need full-length access for frequent product changeovers or sanitation
- Space is not constrained in the linear direction
- Lower capital cost is a priority
Choose Spiral Oven when:
- Cook time > 20 minutes — spiral achieves long dwell in compact footprint
- Floor space is the primary constraint
- Higher throughput within limited floor area is required
Belt Selection & Product Support
Belt choice depends on product characteristics:
- Stainless steel mesh: Best for products needing bottom airflow (bread, pizza, cookies)
- Solid steel belt: For products releasing liquids or needing belt conduction (prepared meals in trays, wet dough)
- Plastic modular belt: Lower thermal mass, non-stick surface. For lower-temperature applications
Exhaust & Emissions
Each zone has an independently controlled exhaust with modulating damper:
- Moisture extraction: exhaust rate matched to product moisture release rate
- Combustion gas venting (gas models): flue per burner zone per local code
- Optional: catalytic or thermal oxidizer for VOC control if required by local regulation
- Heat recovery: exhaust-to-combustion-air heat exchanger recovers 40–60% of exhaust energy
Automation & Recipe Management
Siemens PLC standard with color HMI touchscreen:
- Unlimited recipe storage: zone T° (top + bottom), fan speed, belt speed, steam, exhaust per recipe
- Real-time trending of all parameters with data export for batch records
- Automatic pre-heat sequence: zones reach setpoint in priority order
- Integration with upstream (depositor, former) and downstream (cooler, packer) equipment
