使生泡沫

Without Pasteurism, some enzymes still remain in the green draught beer, among which active protease A and the prior substance of inactive protease A can destroy green draught beer's foam protein, therefore, the foam's stability of green draught beer will be reduced.

纯生啤酒因未经巴氏灭菌而残留一些酶类，其中具有活性的蛋白酶A 及非活性的蛋白酶A 前驱物的存在会直接或间接地破坏纯生啤酒的泡沫蛋白，从而使纯生啤酒的泡沫稳定性降低。

An injection rate of 15μg/g CDF-10 antifoaming agent was normally injected to the top of the coke drum at the final 2-6 h of the coking cycle. It could eliminate 3m foam and increase the effective utilization ratio of the coke drum from 65%to 78%, and resulted in higher throughput. The said antifoaming agent had no poison effect on hydrogenation catalyst.

应用结果表明， CDF-10消泡剂一般于生焦周期的最后2～6 h，以15 μg/g 的量在焦化塔顶注入可以将焦炭塔内泡沫层消除3 m，使焦炭塔的有效利用率由65%提高到78%，处理量也可相应提高，并且不会造成对加氢催化剂的硅中毒。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
