The Global Evolution of Rotating Hot Pot: A Decade-Long Transformation from "Street Snack" to "Efficiency King"

Chapter 1: The Germination Period (2016-2019) – From "Rotating" to "Rotating Well"

In 2016, rotating hot pot was just entering the public eye. The equipment was simple back then: a conveyor belt driven by a motor, a circle of counter seats, and dishes placed on plastic plates circulating on the belt.

The pain points at this stage were obvious: the conveyor belt was noisy, prone to jamming, and difficult to clean; food quality was hard to guarantee due to prolonged exposure; and customers relied on luck to get their desired dishes, with specific orders unable to be delivered promptly.

"Back then, if the equipment could just rotate, it was considered good enough," recalled a catering veteran with ten years in the industry. "But rotating and rotating well are two different concepts."

It was during this period that HaiSheng entered the rotating hot pot equipment field. At that time, the company had already accumulated many years of experience in the revolving sushi equipment sector, with the Japanese philosophy of continuous improvement (kaizen) deeply ingrained in the R&D team's ethos. The team keenly realized that rotating hot pot was not a simple copy of sushi equipment; the characteristics of hot pot—the broth, oil fumes, and ingredients—imposed entirely new requirements on the equipment.

HaiSheng implemented three key improvements tailored for the hot pot scenario:

• Upgraded chain plates to 304 stainless steel, solving the problem of cleaning grease stains.
• Added variable frequency drive to motors, allowing speed adjustment based on customer flow.
• Adopted a double-layer stable structure for the frame, increasing load capacity by 40%.

These three improvements established, for the first time, the concept of "specialized equipment" for rotating hot pot.

Chapter 2: The Explosion Period (2020-2023) – Standardization Demands Amidst the Chain Expansion Wave

Post-2020, rotating hot pot entered a phase of explosive growth. Brands like Long Ge and Xi Jia began chain expansion, opening dozens of stores per year. Chain operation imposed new demands on equipment: standardization, replicability, and ease of maintenance.

"Previously, when opening a single store, equipment could be fine-tuned on-site. But with ten stores, that approach doesn't work," said an operations manager from a chain brand. "What we needed was equipment that could be used right after plugging in upon arrival, with consistent performance across all stores."

HaiSheng's modular design proved its core advantage during this stage. All components were pre-assembled and tested at the factory; on-site installation merely involved assembly. A 100-square-meter store could have its equipment installed within 3-4 days. More critically, the operational parameters – dish circulation speed, delivery vehicle response time, temperature control range – were standardized across different stores.

Concurrently, HaiSheng launched its intelligent variable-track delivery vehicle system, ushering rotating hot pot into the era of "point-to-point delivery." The technological breakthroughs of this system lay in:

Real-time and Optimal Path Planning

Delivery vehicles needed to dynamically calculate the optimal route based on real-time orders and track occupancy. HaiSheng's proprietary scheduling algorithm could complete a full-line path search within 0.1 seconds, simultaneously coordinating up to 30 delivery vehicles without congestion during peak hours.

The introduction of this system gave rotating hot pot, for the first time, an ordering efficiency comparable to traditional hot pot restaurants.

Chapter 3: The Maturity Period (2024-2025) – Industry Leaders Enter, Standards Reshaped

2024 marked a turning point for the rotating hot pot industry. This year, catering giants turned their attention to this once "niche" track: Haidilao successively launched rotating hot pot sub-brands like "Fei Pai" and "Ju Gao Gao," rapidly capturing market share with strong brand equity and supply chain advantages; after years of silence, Little Sheep made a high-profile return to first-tier cities, adopting rotating hot pot as its main format; regional leaders like Sheng Xiang Tang and Yi Wei Fei Niu accelerated national expansion, surpassing historical records for annual store openings.

The entry of major brands pushed industry standards to new heights. They brought not only capital and traffic but also a mature catering management system – imposing stringent requirements on food safety, equipment stability, and operational efficiency. It was precisely while serving these leading brands that HaiSheng underwent another upgrade:

Full-Chain Traceability

Subject to the rigorous audits of top brands, HaiSheng established a traceability system covering the entire supply chain. All raw material suppliers had to pass strict audits, and each batch of steel, motors, and controllers received a unique code, traceable to production dates and operators.

Complete Machine Endurance Testing

A random machine from each production batch was subjected to 1,000 hours of continuous full-load testing, simulating three years of high-intensity use to proactively identify potential issues.

The stringent demands of top-tier brands propelled HaiSheng's transformation from an "equipment manufacturer" to a "system solution provider." A supply chain manager involved in equipment selection for multiple leading brands commented: "Previously, when selecting equipment, we focused on whether it would run and how long it would last. Now, choosing HaiSheng, we look at traceability, early warning capabilities, and integration with our management system. HaiSheng doesn't just sell equipment; they understand the operational logic of catering."

It is this deeply integrated service capability that enabled HaiSheng to establish strategic partnerships with over 80% of leading chain brands between 2024 and 2025. When industry standards are reshaped, only those companies capable of exceeding the standards become the definers of the new ones.

Conclusion

A decade has witnessed the transformation of rotating hot pot from a "street snack" into the "king of efficiency."

As a participant in and witness to this transformation, HaiSheng Intelligent Technology feels deeply honored and acutely aware of its responsibility. Our 16 years of technological accumulation, project experience in over 20 countries worldwide, and deep collaborations with leading brands like Haidilao, Little Sheep, and Sheng Xiang Tang have continuously deepened our understanding of rotating hot pot.

However, we are also keenly aware that the pace of evolution will not stop. What will rotating hot pot look like in the next decade? The answer does not lie solely with us, but in the collective exploration of every catering entrepreneur, every equipment engineer, and every consumer.

HaiSheng is willing to join hands with global partners to continue this exploration of efficiency and experience.
