Method utilizing waste vegetable and animal fat to manufacture candle
A technology of animal fats and candles, which is applied in the fields of fat oil/fat refining, candle preparation equipment, fat production, etc. It can solve the problems of information reporting and product listing without the use of candle raw materials, waste of resources, and increase of carbon emissions. The effect of fully utilizing resources, reducing carbon emissions, and reducing costs

Embodiment 1
[0045] Waste plants, animal fat refining, hydrogenation treatment:
[0046] A. Raw oil pretreatment: After clarification, precipitation, filtration, centrifugation and distillation, the raw oil enters the next stage;
[0047] B. Refining: After degumming, decolorization, deacidification and deodorization, deoxygenation and dehydration, the raw oil enters the next stage;
[0048] C. Hydrogenation: Catalytic hydrogenation of raw oil, and then filtered, post-decolorized, post-deodorized to obtain solid powder "extreme hydride";
[0049] The above "extreme hydride", melting point: 54°C, color: R 3.0, Y 30, peroxide value: 5meq / kg, iodine value: 6gI / 100g. Put this "extreme hydride" in a ceramic container, add 0.1% of the total weight of "extreme hydride" dye and 3% candle essence, mix well, heat to 70°C, stir well until completely melted, put The mold is cooled and formed, and the mold is released as a candle.
Embodiment 2
[0051] Waste plants, animal fat refining, hydrogenation treatment:
[0052] A. Raw oil pretreatment: After clarification, precipitation, filtration, centrifugation and distillation, the raw oil enters the next stage;
[0053] B. Refining: After degumming, decolorization, deacidification and deodorization, deoxygenation and dehydration, the raw oil enters the next stage;
[0054] C. Hydrogenation: Catalytic hydrogenation of raw oil, and then after filtration, post-decolorization, and post-deodorization, a semi-solid viscous "selective hydrogenation product" is obtained;
[0055]The above "selective hydride", melting point: 45°C, color: R 3.0, Y 30, peroxide value 8meq / kg, iodine value 26gI / 100g. Put this "selective hydride" and 58°C fully practiced paraffin in a weight ratio of 70:30, mix evenly in a porcelain container, add 0.2% of the dye and 5% of the total weight of the mixture, and heat to 75 ℃, stir well until it is completely melted, put it into a mold to cool and shap...
Embodiment 3
[0057] Waste plants and animal fats are refined and hydrogenated to obtain a semi-solid viscous "selective hydrogenated product", melting point: 44°C, color: R 3.0, Y 30, peroxide value 8meq / kg, iodine value 32gI / 100g. Put this "selective hydride" and 56°C semi-practiced paraffin in a weight ratio of 60:40, mix them evenly in a ceramic container, heat to 75°C, stir thoroughly until completely melted, put it into a mold to cool and shape, The mold is the candle.
[0058] Described " refining, hydrotreating " are with embodiment 2.
