How do you dilute industrial vegetable oil?

The oil stains on the clothes can be scrubbed with pine spray nasal spray, nasal spray banana water, gasoline, etc., and then soak in salt water for a few minutes, and then rinse with water.

If the silk jewelry is stained with oil, it can be gently washed with acetone solution.

Oil stains on dark clothes can be removed by scrubbing with residual tea leaves.

A little toothpaste mixed with laundry detergent to confuse the grease stains on the washed clothes, and the grease stains can be removed.

Take a little wheat flour, mix it into a paste, apply it to the front and back of the clothes, dry it in the sun, peel off the husk, and then break off the oil stains. In fact, the simplest way is to squeeze out some toothpaste, apply it to the oil-contaminated area, then wet it with water, and rub it with your hands. Then soak the clothes in the laundry detergent solution, knead them a few times, rinse them with water, dry them, and remove the grease and dirt like new clothes.

You can also spray trichloroethylene or carbon tetrachloride, or apply it to the oil stains, and the oil stains will disappear naturally, which is generally available in laundries.

1. Rapeseed pretreatment.

Rapeseed press pre-treatment includes crushing, steaming, frying, and peeling. The purpose of rapeseed peeling is to remove the main fibrous parts and pigments, otherwise the feed value of the cake grains will be reduced. On the other hand, the peel during the qin extraction process is conducive to the penetration of the qi, and theoretically speaking, peeling (i.e., removing 15% of the material at the removal site) will increase the processing capacity of the invasion equipment by 15%.

2. Rapeseed oil production process.

Oilseed rape is first underwent a rail blank to destroy the seeds and rupture the oil cells. The steaming blank ruptures the remaining intact cells, improves fluidity, and passivates enzymes, especially myrosinase. The bad material is disposed of in the steaming and frying pan, steamed and fried at 77 100 degrees Celsius for 15 20min (depending on the variety, in most cases, the billet after rolling and steaming is pre-pressed with a rapeseed oil press, so that the oil content is reduced from 42% to 16% 20%; This pre-pressing process also removes ethane from the fine oil cake at a temperature of 100 to 130 degrees Celsius to remove ethane and improve the nutritional quality of the meal.

Microwave treatment of the enzyme in whole rapeseed and rolled billet to passivate it is an effective method. Glucosin passivation depends on the initial raw material moisture (ideal moisture is 10% of the original material) The disadvantage of microwave treatment is the increased sulfur content in the oil, which is caused by long-term treatment. Many rapeseed processors have added extruders to their processes after and before they are crushed.

This extruder is an auxiliary piece of equipment, and its benefits are sufficient to make the cost worthwhile. The latest design is to combine the pre-press and extruder into a single machine, which has a function that does not require power.
