Fat emulsion tail liquid treatment device and method
Technical Field
The invention belongs to the field of fat milk preparation.
Background
Fat emulsion is a homogeneous and stable fat emulsion consisting of refined soybean oil and refined lecithin, and its therapeutic importance is to provide high energy and essential fatty acids under parenteral feeding. The fat which is absorbed by human body from the stomach and intestine is proved to be absorbed by physiology and nutrition to form chylomicron, and the product has the shape and the composition which are extremely similar to those of chylomicron, and can be directly infused into the vein of a patient who cannot eat food to provide fat nutrition.
The fat emulsion tail liquid treatment process is an important basis for ensuring the product quality, ensuring the normal operation of homogenizer equipment and reducing the production cost, and the domestic current fat emulsion tail liquid treatment process is as follows:
1. the fat emulsion tail liquid is completely discharged and is not recovered. The advantages are that: the product quality is ensured; the disadvantages are as follows: the loss is large, the medicine is homogenized for 6 times according to each batch, 20 kg of medicine is discharged each time, 10 batches are produced in one day, and the loss is large in one day: 20 × 6 × 10 — 1200 kg, bottled in 250ML, lost: 4800 bottles, at a cost price of 10 dollars per bottle, lost one month: 4800 × 10 × 30 ═ 1440000 yuan.
2. And finally, homogenizing the liquid medicine recovered from the storage tank according to a production process, and finally, independently filling. 10 batches are produced every day, each batch is homogenized for 6 times, 20 kg of tail liquid is produced each time, and the tail liquid is recovered together in one day: 20 × 6 × 10 ═ 1200 kg. However, concentrated discharge of the tailings into a storage tank is extremely difficult to operate in the production process, product quality is difficult to guarantee, and the tailings are mixed together in batches and stored for too long, so that the product has great quality risk.
