Description

Technical Field

[0001] This invention relates to the field of chemical technology, and in particular to an integrated equipment for mixing and drying vitamin D3 powder and its preparation process. Background Technology

[0002] Chinese patent application number 202210536591.9 discloses a vitamin D3 mixed powder and its preparation method. The mixed powder comprises, by weight, 70-80 parts of sodium octenyl succinate starch, 15-20 parts of sucrose, and 1-5 parts of sodium ascorbate; and by weight, 1-2 parts of tocopherol, 2-5 parts of medium-chain triglycerides, and 0.1-0.5 parts of vitamin D3. The preparation method includes step S1, preparation of a vitamin D3 emulsion; and step S2, spray drying of the vitamin D3 emulsion from step S1 under nitrogen-sealed conditions to obtain the vitamin D3 mixed powder. This invention effectively avoids vitamin D3 loss, ensuring that the vitamin D3 content in the final mixed powder remains essentially consistent with the initial formulation, thus guaranteeing the accuracy of the vitamin D3 content.

[0003] However, the vitamin D3 mixed powder and its preparation method also have some problems. For example, the mixing and drying are carried out in two separate sets of equipment. This requires transferring the mixed vitamin D3 powder to the drying equipment, which increases the risk of contamination.

The left L-shaped arm 17 can drive the left movable rod 18 to move downward, and the right L-shaped arm 17 can drive the right movable rod 18 to move upward. The two movable rods 18 can drive the left side of the heating tank 4 to rotate downward, and the power motor 10 rotates in the opposite direction.The left side of heating tank 4 rotates upwards, causing it to shake. This shaking of the heating tank 4 causes the raw materials inside to continuously agitate, increasing the uniformity of mixing. After mixing, hot heat transfer oil is introduced through the inlet of heat transfer oil connector 6. The heat transfer oil heats the raw materials inside heating tank 4. The cooled heat transfer oil is output through the outlet of heat transfer oil connector 6. The power to vacuum pump 5 is then turned on, creating a vacuum inside heating tank 4. The moisture in the material rapidly vaporizes under vacuum and is removed, achieving low-temperature, high-efficiency drying to obtain a mixture. During discharge, the right side of heating tank 4 rotates downwards via a shaking mechanism, causing the mixture inside heating tank 4 to collect and discharge through discharge pipe 33, yielding vitamin D3 powder.
