Compact supercritical dryerWith its high efficiency, high precision, and compact design, it has demonstrated unique application advantages in multiple fields, especially suitable for scenarios that require high material structural integrity and cleanliness.
Compact supercritical dryerDetailed introduction to its core application areas:
1、 Materials Science: Preparation of High Performance Porous Materials
Metal organic frameworks (MOFs) and covalent organic frameworks (COFs)
Application scenarios: MOFs and COFs have enormous potential in gas storage, catalysis, sensing, and other fields due to their high specific surface area and adjustable pore size. However, traditional drying methods such as vacuum drying can easily lead to the collapse of pore structures.
Advantages: Supercritical drying eliminates surface tension, maintains the integrity of material pore structure, and significantly improves specific surface area and adsorption performance. For example, in the preparation of MOF-5, supercritical drying can increase its specific surface area by more than 30%.
Mesoporous materials and aerogels
Application scenario: mesoporous silica, carbon gas gel and other materials need high porosity and uniform pore size distribution.
Advantages: Compact equipment can precisely control drying conditions, avoid cracks or shrinkage, and prepare lightweight, high-strength aerogels for heat insulation, sound insulation or catalyst carrier.
2、 Biomedical: Protecting the microstructure of biological samples
Organization and Cell Drying
Application scenarios: Biological samples such as animal tissues, plant tissues, and cells are prone to deformation or rupture due to surface tension during traditional drying.
Advantages: Supercritical drying (such as using CO ₂) can maintain sample morphology and is used for tissue engineering scaffolds, biological specimen preservation, or pre-treatment before 3D bioprinting. For example, when drying plant leaves, the leaf vein structure can be fully preserved for microscopic observation.
Protein and Drug Drying
Application scenario: Protein drugs (such as insulin) need to avoid crystallization or aggregation, and traditional freeze-drying may cause activity loss.
Advantages: Supercritical drying is carried out under mild conditions, reducing the risk of protein denaturation and improving drug stability and bioavailability.
3、 Semiconductor industry: improving wafer and device yield
Drying of silicon wafers after wet etching
Application scenario: After wet etching, if the residual liquid on the wafer surface is not removed, it can cause pattern breakage or adhesion.
Advantages: Supercritical drying (such as CO ₂ fluid) can penetrate micro scale structures, with no residual drying, avoiding the defects of traditional rotary drying or IPA (isopropanol) drying, and significantly improving the yield of crystal circles.
MEMS/NEMS device manufacturing
Application scenarios: Micro electromechanical systems (MEMS) and nanoelectromechanical systems (NEMS) devices require high structural integrity.
Advantages: Supercritical drying can prevent devices from sticking or breaking due to capillary forces during the drying process, ensuring normal functionality.
4、 Food Industry: Improving Food Quality and Shelf Life
Puffed food drying
Application scenario: Foods such as rice and fruits need to maintain an internal fluffy structure to enhance their taste.
Advantages: Supercritical drying is carried out at low temperatures, avoiding nutrient loss and structural hardening caused by high temperatures, while achieving long-term preservation without the addition of preservatives. For example, dried strawberries can maintain their bright color and crispy texture.
Functional ingredient extraction and drying
Application scenario: After extracting natural pigments, fragrances, or active ingredients from plants, they need to be dried and stored.
Advantages: Supercritical drying can retain the activity of thermosensitive components while improving the solubility and stability of the extract.
