In 2016, Jieyi launched independent research and development of membrane filtration equipment for dairy processing.

After 10 years of relentless refinement and innovation, we hereby present a phased summary and share our achievements with our valued customers and industry partners.

Definition in Accordance with Evaluation Standards

Pursuant to QB/T 3921-1999 Terminology for Dairy Machinery, membrane separation equipment refers to devices used for membrane separation operations such as ultrafiltration and reverse osmosis. Membrane filtration equipment for dairy processing is a special hygienic fluid processing equipment based on membrane separation technology, designed for physical sterilization, separation, concentration or component adjustment of milk and other dairy products.By using microfiltration (MF), ultrafiltration (UF), nanofiltration (NF) and reverse osmosis (RO) membranes with different pore sizes individually or in combination under pressure drive, this equipment selectively separates and purifies components such as microorganisms, proteins, lactose and milk mineral salts (ash) in milk emulsions.

Jieyi has achieved No. 1 nationwide sales volume in membrane filtration equipment for dairy processing in China’s light industry sector.

Review of the Development of China’s Dairy Processing Machinery，It is an undeniable historical fact that there was a generational gap between domestic dairy processing equipment and advanced international counterparts in the development process.

1950s–1990s: A Weak Start

Domestic equipment could only meet basic milk collection, storage and simple processing needs. In contrast, developed Western countries were transitioning from manual operation to mechanization and automation, with technologies such as UHT sterilization and aseptic filling emerging.

1990s–Early 21st Century: Foundation for Scaling and Standardization

Domestic equipment laid an initial foundation for raw milk reception, pretreatment, sterilization, concentration, drying and packaging.

Early 21st Century–2015: Diversification and Initial Maturity

A series of specialized equipment (e.g., fermenters, curdling equipment, whey separation equipment) was developed domestically for processing specialty dairy products such as yogurt, cheese and whey powder, satisfying diverse dairy processing demands.

2016–Present: Fast Track of Innovation-Driven and High-Quality Development

Cutting-edge technologies including the Internet of Things (IoT), big data and artificial intelligence have been applied to equipment manufacturing, intelligent control and automated production to boost efficiency, reduce labor costs and minimize human errors, becoming the industry’s development trend. Domestic dairy processing equipment manufacturers are moving toward high-end and intelligent production, gradually narrowing the gap with international advanced levels.

Industrial Prosperity Drives National Development

Technological progress not only lays the foundation for industrial development, but also provides strong supply support for the robust market demand unleashed in China’s modernization drive.

According to industry reports:

• The global dairy processing equipment market reached approximately $12.22 billion in 2025.

• It is projected to grow from $12.91 billion in 2026 to $21.44 billion by 2034, with a compound annual growth rate (CAGR) of about 6.50%.

• The Asia-Pacific region will maintain its dominant position, accounting for around 40% of the global market share in 2026.

Market Trends & Technological Innovation

Against the backdrop of the growing low-temperature dairy and deep processing trends in China, advances in non-thermal technologies (e.g., membrane filtration, pulsed electric field) in recent years have demonstrated great potential to revolutionize dairy production.

Based on 2026 global dairy processing equipment market forecasts (by product type), membrane filtration equipment will account for approximately 15% of the market, and its role in replacing traditional thermal evaporation processes is becoming increasingly prominent.

Technological advancement, market expansion and domestic substitution are advancing in tandem. As a key future direction in the evolution of dairy processing equipment and technology, Jieyi has demonstrated its capability and confidence in ensuring domestic supply security.

From Pastures to Daily Diet

“Eat less, eat better”reflects the evolving dietary behavior, consumption structure and health expectations we are increasingly witnessing.

The dairy industry, which has long centered on protein as its core value proposition and health as its narrative, is now at a critical juncture of category restructuring and consumption reshaping.“Less but better” signifies higher nutritional density, precision manufacturing and function orientation.

Beyond cheese and butter, whey protein, protein peptides, lactoferrin, milk calcium and other ingredients are expanding their presence in China’s dairy manufacturing landscape. Membrane filtration is an indispensable strategic technology for dairy deep processing.

Going beyond filtration to provide a core domestic engine for precision manufacturing and sustainable production, Jieyi will continue to excel in the following areas:

• 
  

• Jieyi Membrane Technology Matrix – Milk Deconstruction and Flexible Production Modules

• Jieyi Milk Protein Deep Processing – Co-production processes for cheese & multi-gradient WPC35-WPC80, and multi-stage MPC-MPI

• Jieyi SuPer UF – Post-fermentation filtration and concentration equipment & solutions for fresh soft cheese, quark, Greek yogurt, etc.

• Jieyi PlantM – Purification and concentration of plant-based foods & beverages (coffee, soy milk, coconut milk, etc.)

• Jieyi X Ecolab – Joint development for continuous optimization of cleaning solutions

• Jieyi X Membrane Element Brands – Comprehensive verification and development experiments for extending membrane element service life

• ......

Many a little makes a mickle; many a drop makes an ocean. Taking this as a new starting point, Jieyi will keep moving forward.
