Embodiment 1

[0040] First weigh each raw material according to the following weight: (in kilograms)

[0041] Calcium hydroxide 4 purified water 6 salad oil 80

[0042] Soy Lecithin 8 Oleic Acid 2

[0043] First put calcium hydroxide into a high-pressure container with an electric mixer, add purified water at the same time and start the mixer to stir evenly, then add 4 / 5 (64 kg) of salad oil and stir evenly. After the above preparations are completed, the high-pressure vessel is heated and pressurized to keep the pressure at 0.12 MPa, and saponification reaction is carried out for 4 hours under this pressure condition. After the reaction, cool down to normal temperature naturally, then filter the material in the high-pressure container, put the obtained filtrate into the high-pressure container, and raise the temperature to 120°C for 40 minutes, add soybean lecithin and the remaining amount of salad after the water is removed oil (16 kg) and stir well while raising the temperature to 138°...

Embodiment 2

[0045] First weigh each raw material according to the following weight: (in kilograms)

[0046] Calcium Hydroxide 6 Purified Water 5

[0047] Salad Oil 76 Soy Lecithin 9

[0048] Oleic acid 4

[0049] First put calcium hydroxide into a high-pressure container with an electric mixer, add purified water at the same time and start the mixer to stir evenly, then add 4 / 5 (60.8 kg) of salad oil and stir evenly. After the above preparations are completed, the high-pressure container is heated and pressurized to keep the pressure at 0.125 MPa, and saponification reaction is carried out for 4 hours under this pressure condition. After the reaction, cool down to normal temperature naturally, then filter the material in the high-pressure container, put the obtained filtrate into the high-pressure container, and raise the temperature to 120°C for 50 minutes, add soybean lecithin and the remaining amount of salad after the water is removed oil (15.2 kg) and stir well while raising the t...

Embodiment 3

[0051] First weigh each raw material according to the following weight: (in kilograms)

[0052] Calcium Hydroxide 5% Purified Water 4%

[0053] Salad Oil 78% Soy Lecithin 10%

[0054] Oleic acid 3%

[0055] First put calcium hydroxide into a high-pressure container with an electric mixer, add purified water at the same time and start the mixer to stir evenly, then add 4 / 5 (62.4 kg) of salad oil and stir evenly. After the above preparations are completed, the high-pressure vessel is heated and pressurized to keep the pressure at 0.125 MPa, and saponification reaction is carried out for 4 hours under this pressure condition. After the reaction, cool down to normal temperature naturally, then filter the material in the high-pressure container, put the obtained filtrate into the high-pressure container, and raise the temperature to 120°C for 60 minutes, add soybean lecithin and the remaining amount of salad after the water is removed oil (15.6 kg) and stir well while raising th...

Abstract

The invention relates to mold oil for medicinal hollow capsule production and a preparation method thereof and belongs to the field of mold oil production and preparation. Calcium hydroxide, salad oil, soybean phospholipid, oleic acid and purified water are used as raw materials; a mold oil finished product is obtained through mixing, stirring, saponification and other steps. The prepared mold oil is flaxen oily liquid with good fluidity; the dosage is small in the using process and no oil mist occurs; the transparency of a transparent capsule is high; in addition, the mold oil is good in intersolubility; delamination is avoided; and the mold oil can be stored for a long time.

Description

technical field [0001] The invention relates to a release oil used in the production of medicinal hollow capsules and a preparation method thereof, belonging to the field of release oil production and preparation. Background technique [0002] At present, the release oil used for capsule production at home and abroad is single oil or compound oil, which is characterized as liquid or solid, such as rapeseed oil, peanut oil, palm oil, olive oil, liquid paraffin, white mineral oil, etc. The following questions: [0003] The oil film is uneven, it is not easy to release the mold, and the service life of the mold is reduced; [0004] Solid grease is inconvenient to use, and the usage amount cannot be controlled; [0005] Composite products are difficult to integrate and easy to separate, affecting production; [0006] Affected by temperature, the viscosity changes greatly and is unstable; [0007] The production of transparent capsules produces oil mist, and the capsules cann...
