    Due to its high FFA content, cod liver oil may require acid esterification (using H₂SO₄) before base-catalyzed transesterification with NaOH or KOH. A two-step method is most effective. For cleaner oil, base catalysis alone suffices. The GlobeCore USB plant supports both acid and base catalysis, with automated control of reaction stages, methanol ratios, and catalyst dosing, making it ideal for processing marine oils like cod liver. Enzymatic transesterification is also an option for small-scale, high-purity applications but is costlier.

    เพื่อตอบกลับ: Which catalysts or additives are most effective for converting mustard seed oil into biodiesel? #317715
    伊藤 聡太郎
    สมาชิก

    Sodium hydroxide (NaOH) and potassium hydroxide (KOH) are the most commonly used base catalysts for mustard oil biodiesel. The oil’s relatively low free fatty acid content usually allows for direct base-catalyzed transesterification without pre-treatment. The GlobeCore USB system is compatible with both catalysts and allows for fine-tuning dosage based on feedstock quality. Antioxidant additives can be used post-production to improve the stability of biodiesel made from high-erucic-acid oils like mustard.

    เพื่อตอบกลับ: How to convert palm oil to diesel? #317413
    伊藤 聡太郎
    สมาชิก

    Converting palm oil to diesel involves transesterification using alcohol and a catalyst. This creates fatty acid methyl esters—biodiesel—that can be used in diesel engines. For best results, the oil should be refined to reduce water and free fatty acids. The GlobeCore USB system ensures high-quality biodiesel output, with modules for heating, reaction, and separation built in. The process is fast, safe, and compliant with international biodiesel regulations.

    เพื่อตอบกลับ: What equipment is needed for biodiesel production from rapeseed oil? #317381
    伊藤 聡太郎
    สมาชิก

    Producing biodiesel from rapeseed oil requires several key components: an oil press (to extract the oil), filtration units (to remove solids and impurities), a reactor for transesterification, and separation equipment for removing glycerin. Optional stages include methanol recovery and washing/drying of the final fuel. The GlobeCore USB biodiesel production plant integrates all essential stages except oil pressing, offering automated heating, mixing, reaction, and separation within one modular system. It is scalable, reliable, and engineered to deliver high yields with minimal labor, making it perfect for professional and industrial use.

    เพื่อตอบกลับ: what is a power factor test? #315011
    伊藤 聡太郎
    สมาชิก

    A power factor test measures the phase difference between voltage and current in a dielectric material, indicating the level of energy loss and the quality of insulation.

    เพื่อตอบกลับ: what happens when a transformer leaks oil? #314955
    伊藤 聡太郎
    สมาชิก

    Cooling in transformers involves dissipating the heat generated during operation, often through natural convection or forced methods (using fans or pumps), with oil acting as the primary coolant.

    เพื่อตอบกลับ: is specification of transformer oil? #314797
    伊藤 聡太郎
    สมาชิก

    Transformer oil specifications include parameters such as dielectric strength, flash point, viscosity, acidity, moisture content, and pour point, ensuring the oil performs safely and effectively.

    เพื่อตอบกลับ: why nitrogen is filled in transformers during transportation #314656
    伊藤 聡太郎
    สมาชิก

    Nitrogen is introduced into transformers during transportation to displace oxygen and moisture, thereby preventing oxidation and degradation of the oil and internal components, which helps maintain the transformer’s performance and prolong its service life.

    เพื่อตอบกลับ: how often should transformer oil be changed #314642
    伊藤 聡太郎
    สมาชิก

    Transformer oil is usually replaced according to manufacturer guidelines and condition-based monitoring; routine changes might be scheduled every five to ten years, but if oil testing reveals significant degradation, contamination, or moisture ingress, an earlier change is recommended.

    เพื่อตอบกลับ: why we use oil in the transformer? #314461
    伊藤 聡太郎
    สมาชิก

    Transformer oil is used primarily for insulation and cooling, helping to prevent electrical arcing and dissipate heat during operation.

    เพื่อตอบกลับ: What impact does effective grinding have on the visual appeal and color uniformity of spice mixtures? #313815

    Effective grinding ensures that color pigments are evenly distributed, resulting in a uniform, attractive appearance. The Colloid Mill GlobeCore produces a consistently milled spice powder that enhances the visual appeal and marketability of the final product.

    เพื่อตอบกลับ: How is the fermentation process applied in some mustard production techniques? #297447
    伊藤 聡太郎
    สมาชิก

    Some mustard recipes use fermentation to enhance flavor and reduce harshness. Specific bacterial cultures are introduced to break down glucosinolates into milder compounds, yielding a balanced taste. This controlled fermentation process also improves texture and digestibility, with parameters such as time, temperature, and pH carefully managed.

    เพื่อตอบกลับ: What affects silica gel absorption capacity during regeneration? #123760
    伊藤 聡太郎
    สมาชิก

    Several factors can affect the absorption capacity of silica gel during regeneration, including the temperature used, the duration of the heating process, and the evenness of the heat application. Overheating can damage the silica gel, while insufficient heating may leave residual moisture, reducing effectiveness. GlobeCore’s regeneration systems are designed to optimize these parameters, ensuring consistent temperature control and even drying. This helps maintain the silica gel’s absorption capacity, ensuring that it is fully restored for reuse.
