Bolaike Completes Freeze-Drying Trial for Graphene, Earning High Praise from Client

Jiangsu Bolaike recently completed a freeze-drying process trial for graphene at the request of a client. The finished product came out as a dry, loose, fine sand-like granule, and after being shipped to the client it received high praise — the freeze-dried material fully retained the original physical structure of the graphene powder, with good overall appearance and quality.

Precision Equipment Built for a Demanding Material

Freeze-drying graphene solution places high demands on a system's temperature control precision and vacuum stability. For this trial, Bolaike recommended a 40-square-meter mid-sized freeze dryer, capable of reaching freezing temperatures as low as -35℃ — below the -5℃ eutectic point of the graphene solution — meeting the requirements of the freeze-drying process.

Dual-Layer Radiant Plate Technology

The equipment is fitted with dual-layer radiant plate technology, in which the hot and cold circuits operate independently. The upper cold circuit uses direct heat transfer to rapidly freeze the material, effectively locking in graphene's microstructure and preventing collapse or agglomeration. The system is also equipped with a domestic-brand vacuum pump, delivering a fast vacuum drop and stable operation to provide reliable support throughout the freeze-drying process.

Process Expertise Behind the Result

On the process side, the Xinshidai Freeze-Drying Research Institute under Bolaike brings together global experts in drying technology. The team developed a precisely controlled freeze-drying temperature curve tailored specifically for graphene, using a staged, gradual temperature-rise drying approach to ensure stable, consistent quality of the finished product.
