The NB series thin film evaporator is an efficient evaporation device that has a wide range of applications in various fields such as chemical, pharmaceutical, and food industries. The following are some of the main application scenarios:
1. Chemical industry field
Concentration and Separation: Used for the concentration of various chemical solutions, such as dyes, pigments, resins, etc. In the production process, dilute solutions containing solutes are evaporated to remove solvents and obtain high concentration products. At the same time, it can also be used to separate mixed solutions with different boiling points, achieving preliminary separation and purification of components.
Recycling solvents: Large amounts of organic solvents are often used in chemical production. Thin film evaporators can evaporate solvents from reaction mixtures or wastewater, achieving solvent recycling and reuse, reducing production costs, and minimizing environmental pollution. For example, recycling solvents such as ethanol and acetone in pesticide production.
Post polymerization treatment: After the polymerization reaction is completed, it is usually necessary to remove impurities such as unreacted monomers, solvents, and oligomers. The NB series thin film evaporator can separate these substances at lower temperatures and shorter residence times, avoiding polymer degradation or cross-linking due to prolonged high temperatures and ensuring product quality.
2. Pharmaceutical field
Drug concentration and refinement: used in the process of drug production to concentrate extracts, fermentation liquids, etc., and increase the concentration of active ingredients in drugs. For example, in the production of antibiotics, vitamins, and other drugs, the aqueous solution containing the drug components is concentrated to an appropriate concentration for subsequent crystallization, drying, and other processes. At the same time, the thin film evaporator can also remove impurities and moisture from the drug solution, playing a role in refining the drug and improving its purity and quality.
Heat sensitive drug treatment: Many drug ingredients are heat sensitive and easily decompose or deteriorate at high temperatures. The NB series thin film evaporator, due to its characteristics of low-temperature evaporation and short residence time, can complete the evaporation process without damaging the active ingredients of drugs. It is particularly suitable for the concentration and drying of thermosensitive drugs, such as some biological products, enzyme preparations, etc.
Pharmaceutical solvent recovery: Similar to the chemical industry, a large amount of organic solvents such as methanol, ethanol, dichloromethane, etc. need to be recovered during the pharmaceutical process. Thin film evaporators can efficiently separate these solvents from wastewater, purify them, and reuse them for drug production, reducing production costs while minimizing environmental pollution.
3. Food sector
Juice concentration: Fresh juice is concentrated through a thin film evaporator to remove some moisture, facilitating storage, transportation, and further processing of the juice. Concentrated fruit juice can be used to produce various foods such as fruit juice drinks, jam, jelly, etc., while also retaining the nutrients and flavor substances in the juice.
Dairy product processing: During the production of milk powder, the film evaporator can be used to concentrate milk, improve the content of solids in milk, and prepare for subsequent spray drying and other processes. In addition, in the production of dairy products such as yogurt and cream, thin film evaporators can also be used to concentrate and adjust the ingredients of the raw materials.
Food additive production: In the production of food additives such as citric acid, malic acid, caramel coloring, etc., thin film evaporators can be used to concentrate and purify the reaction solution, remove impurities and moisture, and obtain high-purity food additive products.
