Teaseed oil refining machine De-acidification of equipment of tea-seed oil fine operates concrete step

Teaseed oil refining machine

Product line of equipment of fine of hill tea-seed oil takes off acid treatment, use method of microtherm alkaline refine normally, this method operation is apt, do not destroy the nutrient structure of grease and part. Below we are specific the operation measure that understands de-acidification of tea-seed oil fine.

1. detects tea-seed oil acid value, increase alkali number certainly. According to acid value computational formula is calculated give theory to add alkali number and exceed alkali number.

2. decides lye chroma according to crude oil acid value, crude oil acid value is in 3 the following, lye chroma é of 10 ° B; 3~5 of crude oil acid value, lye chroma é of 11 ° B; 5~8 of crude oil acid value, lye chroma é of 12 ° B; 8~10 of crude oil acid value, lye chroma é of 14 ° B; Crude oil acid value 10 above, lye chroma é of 16 ° B.

3. warms up processing. Will oily gentle lye rises 60~65 ℃ , to counteract most preparation.

4. is added alkaline counteract. Use gush to drench the law joins lye normally, add inside 10~15min, have mix with appropriate rate at the same time.

5. settling. Wait for grease to arrive eventually after Wen Zhi, stop agitate, settling restricts 6~8 hour. Sedimentation process middleman and guarantor holds temperature 60~65 ℃ , black horn dropt, have bath.

Come here, process of de-acidification of equipment of fine of whole tea-seed oil has been finished, in afore-mentioned operations, should notice lye pH indicator is allocated especially, temperature control and sedimentation time, in order to ensure optimal de-acidification effect.
