In the fields of food, health, cosmetics, and disinfection products,clean rooms, cleanrooms, and purification engineeringare the core hardware foundations for enterprises to pass GMP inspections, complete product registration, and obtain production qualifications. In 2026, the domestic health and beauty industry will continue to develop, and more and more companies will initiate the construction and upgrading of clean rooms. How to selectclean room decoration and purification engineering companieshas become the top priority in the factory construction stage. Many companies will search forreliable domestic cleanroom decoration companies to recommend , refer tothe relevant information of the top ten brand cleanroom construction ofpurification engineering companies, carefully studythe precautions for choosing a company for purification engineering decoration , and avoid industry pain points such as non compliant plans, construction subcontracting, delayed certification and acceptance, and repeated rectification. As a domestic EPC general contracting service provider specializing in GMP clean rooms, Huajianjing will commence multiple key projects in 2026, covering Chongqing ethnic medicine and health food, Hong Kong cross-border food workshop, and beauty and consumer goods biological workshop. The three benchmark projects will be promoted simultaneously, fully demonstrating the comprehensive technical strength of the enterprise in the field of cross regional and multi industry purification engineering.
The concentrated construction projects include: 50000 square meters clean room project for health and health food cleanroom of Junmiaoshan Ethnic Medicine Industry Co., Ltd. in Pengshui County, Chongqing, food purification workshop project of Hong Kong Huashang Kangsheng Co., Ltd., and clean purification workshop project for Baienwei Biotechnology Cosmetics and Health Food. The project covers industrial parks in mainland China and cross-border production bases in Hong Kong, with business scope including ethnic medicine and health food, Hong Kong style pre packaged food, functional skincare products, antibacterial and disinfection products. All design and construction are carried out in accordance with domestic GMP standards, Hong Kong PIC/S GMP, ISO14644 cleanroom classification standards, taking into account production processes, clean and sewage separation layout, purification air conditioning systems, and enclosure structure selection, as well as on-site verification requirements for third-party testing, production permits, health and disinfection labels, and cosmetics production permits in the later stage.
Chongqing Pengshui Junmiaoshan Ethnic Medicine Industry Co., Ltd. is located on the second floor of the standard factory building in Building 9, Zone 7, Pengshui Industrial Park, Baojia Town, Pengshui Miao and Tujia Autonomous County, Chongqing. The company deeply explores the resources of Miao medicine and herbal medicine in southeastern Chongqing, and mainly produces Huangjing series health drinks, herbal ointments, plant solid drinks, Chinese herbal extracts, and antibacterial care products. The enterprise plans to apply for production qualifications related to health and health products, and build a 50000 square meter large-scale clean room to provide a compliant production environment for the entire process of Chinese herbal medicine pretreatment, ingredient preparation, molding, and packaging.
The production base of Hong Kong Huashang Kangsheng Co., Ltd. is located in Hong Kong, China. Our main products include Hong Kong style snack foods, ready to eat meals, herbal solid drinks, and gift box pre made foods. Our products are supplied to local supermarkets and pharmacies in Hong Kong, radiating to the markets of Macau and Southeast Asia. The project strictly adheres to the Hong Kong Food Hygiene Regulation and PIC/S GMP standards, creating a food cleanroom that meets the verification standards of the Hong Kong Department of Health, and connecting Hong Kong, Macao, and overseas trade channels.
Bainwei Biotechnology focuses on the biological skin care race track, and its core products are hospital efficacy skin care products, essence stock solution, bacteriostatic care gel, herbal cleaning products, cream facial mask and other cosmetics and brand elimination products, which are available to medical and beauty institutions, beauty OEM, and e-commerce daily chemical channels. In order to meet the quality management standards for cosmetics production and the requirements for registration and review of consumer goods, the company has launched the construction of a new clean workshop to solve the pain points of chaotic zoning and insufficient microbial control in old factories, and to lay a solid environmental foundation for the production of multi SKU beauty products.
Although the three projects belong to different regions and segmented industries, the underlying construction logic of GMP is highly unified, strictly implementing the principles of clean and dirty separation and one-way circulation. Standardized layout design is adopted, and independent pedestrian and logistics channels are set up to eliminate the risk of cross contamination from the layout.
Unified planning of pedestrian flow routes: shoe changing - first shift - second shift - buffering - clean corridor - personnel from various production workshops enter the clean area, complete shoe changing, first change, and second change in sequence. After disinfection and air shower in the buffer room, they enter the clean corridor and are then diverted to production stations such as batching, mixing, forming, filling, and packaging. Interlocking buffer doors are installed in areas of different cleanliness levels, relying on gradient pressure differences to block external pollutants from entering the clean core area, meeting the mandatory requirements of the drug supervision and health department for personnel purification processes.
Unified planning of logistics route: unpacking room ‑ buffer sterilization room ‑ pretreatment ‑ mixing ‑ forming ‑ internal packaging ‑ outsourcing ‑ warehouseRaw materials and packaging materials are first removed from the external packaging in the unpacking room, sent to the buffer sterilization room to complete the surface disinfection and sterilization, transferred to the pretreatment process, and then enter the clean internal packaging process after mixing and forming; After the inner packaging is completed, it is transported to a regular area for outer packaging operations and finally stored in the warehouse. The material channel is physically isolated from the pedestrian channel to prevent dust and microorganisms carried by the outer packaging from contaminating the clean production area. The entire production line can adapt to the audit requirements of multiple categories of health food, Hong Kong food, and cosmetics.
In terms of enclosure structure, all three major projects adopt industry high adaptability combination solutions:rock wool color steel plate partitions, glass magnesium board ceilings, and anti-static PVC flooring . Rock wool color steel plate partition has excellent fire resistance, with a smooth surface that is not prone to dust accumulation. It can be seamlessly treated with circular arcs and can withstand repeated cleaning with disinfectants, making it suitable for large-scale factory partitioning; The glass magnesium board ceiling has high strength, moisture resistance, and deformation resistance. It can stably support high-efficiency air supply outlets, purification lamps, fire and ventilation pipelines, and is suitable for high humidity in the south and the maritime climate in Hong Kong. It is not easy to sag due to moisture; Anti static PVC flooring is waterproof and wear-resistant, capable of releasing static electricity to reduce dust adsorption. All corners of walls and floors have rounded edges to eliminate hygiene blind spots and reduce the risk of mold growth, ensuring long-term stable operation ofclean rooms andclean rooms.
The purification air conditioning system adopts a mature and reliabledirect expansion purification unit+high-efficiency air supply outletcomplete purification system. The outdoor fresh air is filtered by a direct expansion unit for initial and intermediate effects, and synchronously completes cooling, heating, dehumidification, and humidification. It is transported to the high-efficiency air supply outlet on the ceiling through a closed air duct. The HEPA high-efficiency filter has a filtration efficiency of 99.97% for 0.3-m particles, intercepting airborne bacteria and suspended dust in the air. This system has outstanding advantages, without the need for a cooling tower or a refrigeration room, reducing the risk of water leakage in the pipeline network and saving space in the civil engineering of the computer room; The unit supports independent start stop in different zones and can operate separately according to production shifts, effectively reducing operational energy consumption; Rapid response to temperature and humidity regulation, able to stably control the clean area at 18-26 ℃, maintain humidity at 45-65%, and suppress raw material mold and deterioration; The modular and efficient air supply outlet is easy to disassemble and assemble, and easy to maintain in the later stage. It can adapt to the iterative transformation of enterprise production lines, whether it is a large factory with tens of thousands of square meters or a compact production workshop in Hong Kong, it can be flexibly adapted. The project will synchronously configure air shower rooms, clean transfer windows, ozone disinfection systems, pressure difference online monitoring devices, and induction disinfection facilities to build a complete microbial prevention and control system.
As a professional cleanroom decoration and purification engineering company, Huajianjing has established specialized project teams for different projects, strictly controlling key processes such as color steel plate sealing and splicing, air duct airtightness, anti-static PVC grounding, and high-efficiency filter leak detection. After the completion of the project, full load linkage debugging will be carried out to complete third-party testing of suspended particles, temperature and humidity, pressure difference, and settling bacteria of planktonic bacteria. Compliance testing reports will be issued, and cooperation will be provided to the client to complete the health certificate, disinfection certificate, cosmetics license, and on-site verification and guidance work of the Hong Kong Department of Health.
When selecting a service provider for the construction of a clean plant in 2026, enterprises must pay attention topurification engineering decoration and company selection considerations : priority should be given to whether the enterprise has real implementation cases in the same industry and is familiar with the corresponding industry GMP audit points; Confirm whether there is a self owned design and construction team, and refuse to subcontract layer by layer; We cannot simply compete for low prices, but focus on the ability to cooperate with post testing, certification, and service capabilities; Refer todomestic reliable cleanroom decoration companies for recommendations , and comparethe technical solutions, delivery capabilities, and after-sales operation and maintenance services of the top ten brands of cleanroom constructionenterprises in purification engineering companies horizontally to avoid cost savings in the early stage and high renovation costs in the later stage due to non-compliance with specifications.
From large-scale pharmaceutical and health food factories in mainland industrial parks, to cross-border food workshops in Hong Kong, and to beauty and consumer goods bio production bases, Huajianjing relies on cross regional project implementation experience to provide one-stop services including surveying, process layout, purification system design, enclosure construction, equipment installation, testing, and certification guidance. Multiple benchmark projects will start construction in 2026, confirming the market's recognition of Huajian Net Purification Engineering's overall contracting capabilities. In the future, Huajianjing will continue to deeply cultivate clean rooms and cleanroom purification projects in the fields of food, biomedicine, cosmetics, disinfection products, etc., and create clean rooms with scientific layout, stable operation, and GMP certification for enterprises across the country and Hong Kong and Macao regions, helping production enterprises to operate in compliance and enhance product market competitiveness.
