What industries can the laboratory low-temperature spray dryer be widely used in?
Date: 2025-10-15Read: 6
As an advanced drying equipment, low-temperature spray dryer has been widely used in many industries with its unique low-temperature drying technology. The following is a detailed analysis of its main application industries:
1、 Technical characteristics and working principle
Low temperature spray dryer adopts the technology of "low temperature+short time", and the inlet air temperature is usually controlled within the range of 30-80 ℃, which is especially suitable for drying heat sensitive materials. Its core technical features include:
1. Micron level atomization technology: converts the liquid into fine droplets, increasing the specific surface area.
2. Instantaneous drying cycle: The drying process usually takes only 1.5 seconds to complete.
3. Accurate temperature control: With a temperature control accuracy of ± 1 ℃, it avoids the damage of high temperature to bioactive ingredients.
4. High activity retention rate: Under constant temperature mode at 50 ℃, the retention rate of active substances such as proteins and peptides can exceed 95%.
2、 Main application industries
1. Food industry
Dairy products, such as milk and yogurt, can retain nutrients such as protein and fat when dried at low temperatures.
Fruit juices: Orange juice, apple juice, etc., can maintain vitamins, pigments, and original flavor.
Probiotic products: temperature sensitive, low-temperature drying can effectively retain probiotic activity.
Instant food: such as coffee powder, seasonings, etc., maintain the original quality of the food.
2. Pharmaceutical industry
Antibiotics: High temperature can easily cause decomposition and deterioration, while low-temperature drying can reduce the loss of active ingredients.
Enzyme preparations: maintain the catalytic activity of enzymes and ensure product quality.
Traditional Chinese Medicine Extract: Retains the active ingredients of traditional Chinese medicine and improves the efficacy of the preparation.
Peptide drugs, such as semaglutide, can maintain their biological activity by low-temperature drying.
3. Biological products field
Vaccines: Active ingredients are highly sensitive to temperature, and low-temperature drying can maintain vaccine activity.
Serum: prevents denaturation of proteins and bioactive substances.
Bioactive peptides: retain their specific biological activity.
Cell culture: Maintain the structural and functional integrity of cells.
4. Chemical industry
Polymer materials: Control polymerization or decomposition reactions to ensure product quality.
Catalyst: Maintain active ingredients and improve catalytic efficiency.
Ceramic adhesive: preparation of water-based polyurethane (WPU) powder.
Nanomaterials: providing precise control for the preparation of nanomaterials.
5. Environmental protection field
Wastewater treatment: drying harmful substances in wastewater.
Waste gas treatment: realizing the resource utilization of waste.
Organic solvent recovery: Specially designed equipment can process materials containing organic solvents.
