Problems solved by technology

[0003] The defoamers commonly used in molasses alcohol fermentation plants mainly include the following types: (1) Natural oils are cheap and easy to get, but the defoaming ability is not strong, and it is difficult to meet the defoaming requirements of large-scale production when used alone; (2) Red oil powder has strong defoaming ability, but it is harmful to human body; (3) Polyether defoaming agent has strong defoaming ability, but the ability to control foam for a long time is weak; (4) Fatty acid ester defoaming agent , silicone defoamer, all have good defoaming and antifoaming properties, but because they have not been developed for the characteristics of molasses alcoholic fermentation, the application effect is not ideal

Abstract

The invention discloses a defoaming agent used for molasses alcohol fermentation, which comprises the following raw materials in parts by weight: 6-16 parts of polydimethylsiloxane, 6-10 parts of mixed emulsifier, 4-12 parts of polyether and 4-12 parts of polyglycerol fatty acid ester. The defoaming agent used for molasses alcohol fermentation disclosed by the invention has an excellent foam eliminating and restraining performance and a better use effect.

Description

technical field [0001] The invention relates to a defoamer for molasses alcoholic fermentation. Background technique [0002] The fermented liquid that uses molasses to make alcohol contains more foaming substances. In addition to colloidal substances such as protein and starch, there is also a class of high-molecular-weight water-soluble surface-active compounds whose main components are steroidal saponins. The viscosity is very high, so the foam in the fermentation broth is very stubborn. The amount of foam is related to the yeast strain, molasses raw material, ventilation and process management. The appearance of foam will reduce the effective loading coefficient and equipment utilization rate of the fermentation equipment, and may also cause the material to overflow from the tank top, resulting in sugar loss, reducing fermentation efficiency and even topping the tank phenomenon, increasing the chance of pollution. In addition, too much persistent foam will affect the r...
