Pilot Center

The development of CCGB project has made the traditional "three-step" mode of small-scale test, pilot test and industrial production into a solid "five-step" mode: laboratory small-scale test exploration process, small-scale test, large-scale test, large-scale production and specialized scale production. It can effectively avoid the risk of blind investment in enterprise projects due to immature market and technology.
Verification function of connecting the preceding and the following
In the "five-step" mode, the pilot test center undertakes the task of "first-level amplification and second-level amplification". The pilot center plays the functions of process parameter verification, equipment selection, cost estimation, product quality verification, etc. The success or failure of the pilot scale-up directly determines the success or failure of the project production transformation.
condition and foundation
The pilot center was established in 2008, covering an area of 630 square meters and with a total equipment value of about 17 million yuan. It has 7 pilot production lines, including oil-soluble pigment pilot workshop, water-soluble pigment pilot workshop, low-temperature extraction pilot workshop, product crystallization and chromatographic separation pilot workshop, nutrition and medicinal extract pilot workshop, supercritical pilot workshop and spray preparation pilot workshop. In 2025, the Pilot Center was honored as the Hebei Provincial Pilot Demonstration Platform for the Industrialization of Natural Plant Extracts. CCGB's goal is to build a well-equipped pilot center and a pilot platform of the world's advanced level.
Function and equipment

The pilot plant is divided into seven parts: a scale‑up pilot line, a 200‑litre pilot line, a 500‑litre pilot line, a multifunctional anaerobic extraction pilot line, a 2000 L crystallization pilot line, a 1000 L crystallization pilot line, and a chromatographic separation pilot line, which can accommodate 5–6 pilot tests simultaneously.

Each line basically covers the equipment required for the complete process chain of extraction, filtration, separation, concentration, purification, and drying.

In terms of extraction function, it can perform general spray extraction, immersion extraction, as well as ultrasonic extraction and oxygen‑free extraction. For product liquid‑solid separation, disc centrifuges, tubular centrifuges, flat‑plate centrifuges, bag‑pulling centrifuges, ceramic membrane filtration, etc. can be used. Concentration equipment includes nanofiltration membranes, thin‑film evaporators, falling‑film evaporators, molecular distillation units, and deodorising vessels. For product refinement, resin columns, chromatographic separation, and crystallization can be employed. Premixing and grinding equipment comprises colloid mills, homogenisers, emulsifying tanks, and nano‑grinding machines. Drying methods include vacuum oven drying, microwave drying, rake drying, drum drying, and spray drying.

In addition, the pilot centre also hosts several other pilot platforms, such as supercritical fluid extraction, spray granulation drying, emulsion preparation, and microencapsulation. Together, these platforms form the Chenguang Biotech pilot platform system.

Since its establishment, the pilot centre has successfully completed hundreds of projects of various scales for the company. It not only serves the company internally but is also open to external users, providing pilot testing and trial production services for R&D projects to other research institutions, enterprises, and public organisations.
