What type of defoamer is good for biological fermentation

Is chicken manure better breathable or stuffy and not breathable during rapid fermentation?

Defoamer for biological fermentation. It can eliminate biological fine bubbles, static and dynamic fine bubbles, large bubbles, viscous liquids; It can not break the bacteria and defoam quickly, inhibit the foam for a long time, the dosage is low, and it is non-toxic, non-bad, especially for water-based steriles. It is easily dispersed in water and is well compatible with liquid products.

Generally, polyether defoamers are selected, such as bio-fermentation defoamers. They are biologically inert as defoamers. It can be directly added to the fermentation broth with the base material, and the stability before fermentation and the inhibition of growth during the fermentation process, as well as the shortcomings of the scaling of the fermentation tank, and have the advantages of easy separation after fermentation and easy cleaning of the tank.

Biological fermentation technology is the process of using microorganisms to complete the growth, reproduction and metabolism under suitable conditions under the condition of sufficient raw starch. As an emerging technology, biological fermentation technology has developed rapidly and has an important impact on human life and social development.

Biological fermentation technology is also used in the process of alcohol production, but foam is more likely to be produced in this process, which can affect the fermentation process and the quality of the product.

Bio-fermentation defoamer is a defoamer specially designed for various fermentation processes, with excellent dynamic defoaming, foam inhibition performance and long-lasting defoaming ability. It does not interfere with the fermentation process, keeps the foam at an acceptable level, and achieves the desired defoaming effect with very low dosages.

It is not possible to use the defoamer for biological fermentation imported from Guangbai.

Industrial fermentation defoamer is a special fermentation defoamer that is biologically inert and refined by a special process. According to the characteristics of the fermentation process, it can be directly added to the fermentation broth together with the base material, and the shortcomings of the growth and scaling of the fermentation tank during the fermentation process are overcome by high temperature fed-up or feeding, and the advantages of easy separation after fermentation and easy cleaning of the tank.

Industrial fermentation defoamer is a biologically inert defoamer that does not hinder the growth of microorganisms when used.

The basic characteristics of defoamers for industrial fermentation are that they do not react with raw materials and do not affect the fermentation process, so they do not affect the growth of fermentation microorganisms.

Industrial fermentation is different from general fermentation, and the various microorganisms used are chemoheterotrophic bacteria isolated from nature, which grow and carry out various metabolic activities under the conditions of deterioration and natural conditions in laboratory and industrial production, and are needed in many places in industry. However, in the fermentation process, due to the reaction between microorganisms and fermentation raw materials, this process will produce a large amount of foam, and if there is too much foam and it is not treated in time, then the produced products will have a series of quality problems. Next, we will introduce a method for dealing with industrial fermentation foam, which is the use of industrial fermentation defoamers.

Industrial fermentation foaming is caused by many reasons, the main reasons can be divided into the following three points: First, the physical stirring of machinery and equipment is unreasonable or the stirring time is too long, which will lead to the production of foam. The second is the metabolic reaction of microorganisms, when there are too many microorganisms growing in the medium, their metabolism will be very frequent, which can easily lead to the production of foam.

Third, the change of temperature environment will also lead to the generation of foam, which will affect the progress of industrial fermentation.

The solution has been mentioned above, which is to use industrial fermentation defoamers. It is specially made to solve the problem of industrial fermentation foam, it can effectively solve the foam problem, according to the characteristics of biological fermentation process, choose to add in the fermentation base material, or in the later stage after high temperature sterilization to produce bubbles and then flow addition, adding industrial fermentation defoamer in the base material is better than adding in the fermentation follow-up process, and the foam inhibition time is longer. Moreover, it will not affect the fermentation microorganisms, and has the advantages of low dosage, strong water dispersibility, attached suction, and low surface tension.

Final summary: The defoamer used in industrial fermentation minutes does not affect the growth of microorganisms.

The amount of defoamer added for fermented food is generally the total foaming system, and the specific economical dosage needs to be tested in practice.

1. Add the defoamer to the foaming system to ensure its uniform dispersion. If dilution is to be made, it is best not to store the dilution for more than 24 hours.

2. For the system with high foaming temperature (> 60), it is recommended to add the defoamer or diluent to the system before 60 and disperse evenly to exert its maximum effect.

3. According to the viscosity, temperature and stirring of different foaming systems, the more economical dosage is selected in units of 10ppm, and generally speaking, the dosage of 30-200ppm can ensure the ideal defoaming effect. Some industries, such as fermentation, may require 2-5 years of biological fermentation

China's "Hygienic Standards for the Use of Food Additives" stipulates that the maximum amount used for brewing process is 1g kg, the soy product process is 3g kg for sugar making process and fermentation process, and the amount of addition for general industrial use is about 1g. Dosage of liquid edible defoamer:

1) Soy products, beer manufacturing: add this product to use; 2) Juice, beverage, ice cream manufacturing: add this product to use; 3) Manufacture of condiments, sugar and fermented products

Add to this product and press to use. The dosage of solid edible defoamer, when the defoaming material is more than 50, this product is added according to the weight of the material.

The recommended addition amount is 1 3-1 2 of the amount of polyether and silicon defoamer.

It has been proved by professional tests that a reasonable addition ratio is determined according to the characteristics of the fermentation process before use, and it is easy to increase the yield; Excessive addition of defoamers may have a negative effect on culture growth.

Depending on the characteristics of the fermentation process, it can be added to the base material or after autoclavage at a later stage.

When used, it can be used miscible with vegetable oils such as soybean oil to defoam.

Fermented food defoamers have a relatively high solid content, so the amount can be between 8 and 1 percent per thousand. It is best to dilute after use.
