In glass bottle production lines across the daily chemical and baijiu (Chinese liquor) industries, there is one workstation that has always been a headache for production managers—the entrance of the high-temperature annealing furnace.

Glass bottles come out of the forming furnace at extremely high surface temperatures, with intense heat radiating from the furnace mouth. Workers must rotate shifts every 30 minutes to 1 hour; otherwise, heatstroke or burns are highly likely. Even with high-temperature subsidies, it remains extremely difficult to recruit for this position.

On the other side, the primary packaging workshop in the food industry faces a different kind of concern. Meat products, pasta, and ready-to-eat foods must be manually sorted before entering packaging machines. Manual operation is not only inefficient but also introduces safety risks—any lapse in hand disinfection may lead to microbial contamination of an entire batch.

Conventional Delta robots may be applicable, but their material and protection level do not meet food-grade standards, making them unsuitable for direct contact with unpackaged materials.

These two seemingly unrelated scenarios point to the same question:

Is there a robot that can withstand high temperatures while also meeting food-grade safety and cleanliness requirements?

From Materials to Real-World Testing

Solving the Challenges of High Temperature, Food Grade, and Cleanliness

ATOMROBOT stainless steel Delta robots are not simply standard models with a stainless steel shell added on top. Instead, they are redesigned from the ground up in terms of materials, protection systems, and thermal management.
 

Material & Protection Design

The entire robot body is made of 304 food-grade stainless steel, with optional food-grade wear-resistant materials for joint components.

This allows the robot to directly handle unpackaged meat products, pasta, or ready-to-eat foods without risk of particle shedding or corrosion over long-term operation. The surface is smooth and easy to clean.

Standard protection rating is IP55, with certain models customizable up to IP65, meeting the high-frequency washdown requirements of food workshops and daily chemical production lines.

High-Temperature Adaptation

The WC series can be equipped with a water-cooled enclosure system.

A circulating coolant continuously removes heat generated by the motor, keeping operating temperature within a stable and safe range.

Even when deployed near annealing furnace entrances—handling freshly formed high-temperature glass bottles—the robot maintains stable operation without frequent overheating alarms or shortened lifespan issues common in standard robots.

Performance Specifications

• Payload: 3–5 kg
• Maximum working diameter: up to 1600 mm
• Repeatability: 0.05 mm
• Standard cycle speed: up to 180 cycles/min (25-305-25 mm motion path)

Different models can be matched to production line requirements in terms of space and speed.

Can a standard robot with a stainless steel cover achieve the same performance?

Field comparative tests show:

• Conventional robots experience significantly reduced motor lifespan and increased failure rates after continuous operation in high-temperature environments.
• ATOMROBOT WC series, with its water-cooled system, maintains stable motor temperature and has operated for thousands of hours at furnace entrances without overheating-related shutdowns.
• In food-grade environments, lubricants and coatings in conventional robots may pose contamination risks. In contrast, ATOMROBOT’s stainless steel body and food-grade wear-resistant joints have passed third-party testing, meeting requirements for direct contact with unpackaged food.

All data above are derived from real deployed projects.

Multiple Real-World Scenarios

One Unified Solution

Case 1: High-Temperature Glass Bottle Feeding into Annealing Furnace (Daily Chemical & Baijiu Industry)

A large baijiu manufacturer previously required 4 workers per day for shift rotation at the furnace station, with each worker able to withstand only about 1 hour in the high-temperature environment.

After deploying ATOMROBOT D3WC-1300-P5 (with water cooling system), the process became fully automated and unmanned.

• Energy consumption: < 2 kWh per hour
• Annual maintenance cost (consumables + servicing): ~10,000 RMB
• ROI: less than 1 year
• Result: completely eliminated labor shortage issues

Case 2: Unpackaged Food Sorting into Packaging Machines (Meat & Ready-to-Eat Foods)

A meat processing company previously relied on 3 workers per shift across three shifts. Frequent contact with unpackaged cooked food required repeated disinfection, and occasional lapses led to microbial contamination in quality inspections.

After adopting ATOMROBOT D3PC-1100-P3 (stainless steel body + IP65 protection):

• Sorting process became fully unmanned
• Product qualification rate significantly improved
• Energy consumption: < 1.5 kWh per hour
• ROI: within 1 year

These two cases represent the two core value propositions:

• High-temperature resistance
• Food-grade safety & hygiene

They are also the most frequently requested application scenarios from customers.

Purpose-Built for High Temperature and Hygiene Applications

For production lines facing challenges such as:

• labor shortages at annealing furnace stations due to extreme heat
• difficulty in automating food sorting due to hygiene requirements
• frequent failures of standard robots caused by daily high-pressure washdown
