Abstract

The invention relates to a method for preparing a defoaming agent for methanol protein production, effectively solving the problems of complex production process, high cost, poor effect, toxic effect and product yield influencing. The method comprises the following steps: mixing big cotton grass, mosaic scirpus tabernaemontani, soybean stems and locust branches by weight, burning into powder, adding water, heating, adding simethicone, and heating for stewing to obtain a first-time mixture; mixing hornwort, bermuda grass, wheat straws and dandelion by weight, burning into powder, adding water, heating, adding soybean oil, and heating for stewing to obtain a second-time mixture; mixing cornstalks, castor stems, willow twigs, apple branches and passion flower by weight, burning into powder, adding water, heating, adding colza oil, and heating for stewing to obtain a third-time mixture; and mixing the first-time mixture, the second-time mixture and the third-time mixture, and heating for stewing to obtain the a defoaming agent. The production process is simple, raw materials are easily obtained, the defoaming and foam inhibition effects are good, and the defoaming agent is particularly suitable for methanol protein production.

Description

technical field [0001] The invention relates to a method for preparing a defoamer used for methanol protein production. Background technique [0002] In the process of microbial fermentation to produce methanol protein, a large amount of protein often leads to the formation of a large amount of foam in the fermentation liquid, which not only affects the dissolved oxygen level of the fermentation liquid, but may also cause overflow of the tank and lead to bacterial contamination, which ultimately affects the smooth production. Antifoaming agents must be used during protein fermentation to reduce foam. [0003] At present, there are many kinds of defoamers, mainly oils, polyethers, polysiloxanes and sulfonated oils. However, the application of these defoamers has certain limitations. Some of them have complex production processes, are expensive, and some are inconvenient to use and have poor effects. Although some defoamers have good defoaming effects, they are toxic to micro...
