On the path of technological innovation, the most exciting breakthroughs sometimes arise not from carefully designed blueprints, but from an unexpected mistake. Just like the "Crying Horse" incident - a classic case of a completely new chemical reaction unexpectedly triggered by operational errors - many revolutionary discoveries are wrapped in the cloak of chance. In the field of dry ice industry in China, the R&D team of Hefengli Dry Ice also experienced such a beautiful accident firsthand.

After a year of repeated iterations and testing, the Hefengli R&D team unexpectedly found the key to optimizing the dry ice production cavity in a trial error. This breakthrough greatly improved the conversion rate and production capacity of dry ice, and as a result, successfully applied for national patent technology, becoming another hard core medal in the company's technological treasure trove. But this is not simply luck, but the inevitable crystallization of 26 years of relentless pursuit of technology and quality. Today, let's take a look at how it transforms a coincidence into an inevitability that leads the industry.

Tip 1

The 'Crying Horse' Incident

The "Crying Horse" event is a phenomenal commercial and cultural event that attracted wide attention in China's Internet and consumer markets in early 2026. Its core is a plush toy born due to production errors, which unexpectedly became popular and generated huge market demand. The starting point of the event was an accidental mistake on the production line. When sewing a mascot doll of the Year of the Horse originally designed for smiling expression, workers mistakenly sewed the upturned mouth and powder blusher in the opposite direction, resulting in the finished product showing a "grievance face" with drooping mouth corners and powder blusher nostrils downward. In early January 2026, a netizen received this "defective product" and shared its photos and purchase experience on social media, which unexpectedly sparked widespread attention and resonance. Netizens jokingly referred to it as the "hidden item" or "crying horse", and began to consult and purchase in large quantities, quickly making it a hot topic on the internet.

26 years of deep cultivation: the technological long march from equipment manufacturers to builders of the entire industry chain

Established in 1999, Hefeng Li Dry Ice has already surpassed its role as a mere equipment manufacturer. Over the course of 26 years, it has built a complete industrial chain of "carbon dioxide capture and recovery dry ice production and manufacturing cleaning equipment research and development cold chain transportation development". This industrial chain is a link that connects diverse technologies and creates collaborative value. And consolidating this industrial chain is precisely its investment in technology research and development at no cost and almost obsessive pursuit.

A technical team with 26 years of experience has accumulated in the company, carrying the belief of "perseverance" in technology, and together they have written a chapter in our industry. From establishing 20 dry ice factories globally to accumulating over 80 patented technologies, every step confirms our persistence. We are committed to bridging the entire industry chain of dry ice industry, establishing a solid industry moat with technology, and successfully breaking foreign technological monopolies with technology, achieving a leap from catching up to leading.

The accidental to inevitable development of cavity technology: the hard core strength behind patents

The breakthrough in dry ice production cavity technology mentioned earlier is a significant contribution to the long history of Fengli Technology. The core achievement is the independently developed "cavity pressure balance system". This technology cleverly utilizes a stable pressure exhaust design, achieving the same production capacity with a smaller cavity.

Its revolution lies in the astonishing 53% reduction in the heat exchange area between the new cavity and the environment. Under the same production capacity conditions, this means that the dry ice conversion rate is greatly improved, while significantly saving system power consumption. This technology is not only an optimization of the company's own products, but also evaluated as an outstanding contribution to the global dry ice industry.

The birth process of this patented technology is precisely the modern industrial version of the "crying horse" innovation. After a year of repeated testing, countless days and nights of data and adjustments were recorded. The ultimate success sprouted from an unplanned mistake. This vividly illustrates that on the basis of solid theoretical accumulation and extensive experimental groundwork, the value of chance will shine. It is the best reward for R&D personnel who never give up, are observant, and can see new possibilities from failure.

Tip 2

What is a 'cavity'?

'Mold cavity' is a core term in the field of mold manufacturing, specifically referring to the cavity structure used in molds to shape the outer surface of products in dry ice manufacturing equipment.

In the field of dry ice manufacturing machines, "cavity" is a core concept, which specifically refers to the key component that compresses and shapes liquid or snowflake shaped carbon dioxide into solid dry ice particles or strips. The design, structure, and function of the dry ice machine cavity directly determine the yield, density, shape, and purity of dry ice.

Tip 3

The core function of dry ice machine cavity

Compress and extrude snowflake shaped carbon dioxide powder into shape. Its basic structure usually includes a compression cylinder (or compression chamber) and a piston (or plunger) that cooperates with it. Liquid carbon dioxide enters the chamber through a pipeline, and some of it vaporizes instantly to absorb heat, causing the other part to solidify into a snowflake like solid. Subsequently, the piston undergoes reciprocating motion driven by hydraulic or mechanical force, exerting immense pressure on the snowflake shaped dry ice, forcing it to pass through the forming mold at the front end, thereby forming high-density strip or granular dry ice.

Witness of Quality: A Trust Letter Written Together by Time and Customers

Top tier technology ultimately needs to undergo rigorous testing over time and in the market. Hefengli's pursuit of quality is not only written on patent certificates, but also engraved in customers' trust for eight years.

In 2024, He Fengli was invited to visit an old customer - Yong'an Zhisheng Chemical. Customer feedback shows that after 8 years of continuous operation, the 6 Fengli dry ice granulators purchased in 2016 still have extremely low failure rates, high production efficiency, and energy savings, fully meeting production needs. This affirmation from an "eight year old friend" is more powerful than any advertisement to prove the reliability and durability of the equipment from Fengli.

In addition, the company's confidence in product performance is built on solid overload testing. For example, it conducted an uninterrupted overload test on the HP-1000plus dry ice granulator for up to 300 hours. The equipment's production capacity remained stable at around 1060 kg/hour, the fuel tank temperature was maintained at around 40 ℃, the dry ice conversion rate reached 2.2:1 (i.e. 1 ton of dry ice was produced for every 2.2 tons of liquid CO2), and the quality of the produced dry ice was excellent. This kind of hardcore testing that speaks with data is the source of confidence in its quality commitment.

From chance to necessity, craftsmanship is evident in every detail

From capturing innovative cavity technology from a trial error, to 20 factories and over 80 patents worldwide; From the powerful equipment that withstands 300 hours of overload testing, to the enduring trust that has won customers' loyalty for eight years - and Fengli Dry Ice has spent 26 years interpreting what the spirit of craftsmanship and long termism are.

True progress comes from tolerance for differences, from injecting human warmth and relentless exploration into seemingly cold industrial rules. The story of 26 years with Fengli tells us that the gift of "chance" will only be given to explorers who have already paved the way with sweat and perseverance.

Hefengli will continue to use technology as the propeller and quality as the sail, breaking through the waves to help Chinese manufacturing move towards green and intelligent development.

Hefengli,

Deeply cultivating the entire field of dry ice with industrial craftsmanship,

With a persistent spirit,

Create a new benchmark in the industry!
