The core advantage of WFE thin film evaporator (i.e. scraper thin film evaporator) is its suitability for evaporating, concentrating, desolving, and purifying materials that are thermally sensitive, highly viscous, prone to crystallization or scaling. With its short residence time and low-temperature evaporation characteristics, it is widely used in industries such as pharmaceuticals, chemicals, food, and light engineering that require high material thermal sensitivity and separation accuracy.
1、 Pharmaceutical industry: Core adaptation for heat sensitive material processing
In the pharmaceutical industry, a large amount of materials (such as active ingredients and intermediates) have strong thermal sensitivity and are easily decomposed at high temperatures. WFE thin film evaporators can meet their separation and purification needs.
Production of active pharmaceutical ingredients and intermediates: used for evaporation concentration, desolvation, or refining of active pharmaceutical ingredients such as antibiotics and vitamins. For example, in the production of vitamin C, concentrated thermosensitive vitamin C solution; In antibiotic production, remove solvents (such as methanol and ethanol) from the reaction solution to avoid high temperature damage to the active ingredients.
Concentration of traditional Chinese medicine extract: concentrate the decoction and alcohol extract of traditional Chinese medicine at low temperature, retain the effective active ingredients (such as flavonoids and saponins) in traditional Chinese medicine, avoid the decomposition of ingredients and the reduction of efficacy caused by traditional high-temperature concentration, and apply to the production of traditional Chinese patent medicines and simple preparations oral liquid, granules and other preparations.
Purification of medicinal excipients: Purify medicinal excipients such as polyethylene glycol and propylene glycol, remove impurities and low boiling point components through evaporation, and ensure that the purity of excipients meets pharmaceutical standards.
2、 Chemical industry: Dealing with difficult material separation conditions
In the chemical industry, there are many materials with high viscosity, easy crystallization, and easy scaling. WFE thin film evaporators can solve the problems of blockage and low efficiency of traditional evaporators.
Chemical industry: used for evaporation concentration or desolvation of dyes, pigments, and coating intermediates. For example, in dye production, concentrate high viscosity dye mother liquor to avoid crystallization and equipment blockage; In the production of coating resins, solvents such as toluene and xylene are removed from the resin to control the solid content of the resin.
Petrochemical industry: Processing petroleum by-products such as lubricating oil, paraffin, asphalt, etc. for dewaxing, deodorization, or concentration. For example, in the refining of lubricating oil, light components are evaporated and removed to improve the viscosity and purity of the lubricating oil; In paraffin production, low-temperature evaporation separates impurities to ensure paraffin quality.
Polymer materials: used in the later stage of polymerization reactions of polymers (such as polyamide and polyester) to remove unreacted monomers and oligomers, improve polymer molecular weight and purity; Or process high viscosity polymer solutions and concentrate materials to meet subsequent processing needs.
3、 Food and agricultural product processing industry: ensuring product quality and nutrition
The food industry has high requirements for preserving the flavor and nutritional content of materials, and the low-temperature short residence characteristics of WFE film evaporators can preserve the original quality of food.
Fruit and vegetable juice concentration: Concentrate fruit and vegetable juices such as orange juice, apple juice, grape juice, etc., evaporate water at low temperatures to avoid the loss of nutrients such as vitamin C and polyphenols, while retaining the original flavor and color of fruits and vegetables. It is suitable for the production of concentrated fruit juice and fruit and vegetable powder.
Concentrate animal and plant extracts: Concentrate soy protein, collagen, plant essential oils, and other extracts. For example, in soy protein production, concentrated protein extract reduces protein denaturation; In plant essential oil extraction, the essential oil is separated from the extraction solvent to ensure its purity and aroma.
Sugar processing: Processing high viscosity syrup (such as glucose syrup and malt syrup), low-temperature concentration to increase sugar concentration, avoiding high temperature causing syrup coking and discoloration, ensuring product taste and appearance.
4、 Light Industry: Adapting to the Separation Requirements of Special Materials
Some products in the light industry involve heat sensitive or high viscosity materials, and WFE thin film evaporators can meet their process requirements.
Daily chemical industry: used for the concentration and purification of cosmetic raw materials such as glycerol, hyaluronic acid, and plant extracts. For example, in the production of hyaluronic acid, the concentrated fermentation broth is used to avoid high temperature damage to its molecular structure; In glycerol purification, impurities and low boiling point components are removed to obtain high-purity medical or cosmetic grade glycerol.
Paper industry: Recycling alkali and organic matter from papermaking black liquor, increasing solid content by evaporating and concentrating black liquor, providing conditions for subsequent alkali recovery and organic matter combustion, while avoiding impurities in black liquor from scaling and blocking equipment.
5、 Environmental Protection and New Energy Industry: Treatment of Difficult to degrade or Special Waste Liquids
In the fields of environmental protection and new energy, WFE thin film evaporators can treat high concentration, heat sensitive waste liquids or materials that are difficult to handle with traditional processes.
Environmental wastewater treatment: Concentrate high concentration organic wastewater (such as pharmaceutical wastewater and chemical wastewater), reduce wastewater volume, and lower subsequent treatment costs; Or recycle useful components (such as solvents and organic compounds) from wastewater to achieve resource recycling.
Production of new energy materials: processing the preparation solution of lithium battery electrode materials (such as cathode material precursors and electrolytes), concentrating the materials to control concentration, and meeting subsequent synthesis or processing needs; Or purify new energy related solvents (such as dimethyl carbonate), remove impurities, and ensure battery performance.
