2021-01-29
The technology of low temperature centrifugal spray drying is used to ensure that the ingredients of corn steep liquor are not damaged. It is widely used in the fermentation of industrial enzymes (amylase, glucoamylase, fungal enzyme, etc.), vitamins (VC, VB2, etc.) and amino acids (glutamate, monosodium glutamate, lysine, tryptophan, threonine, methionine, phenylalanine, etc.). Corn steep liquor powder is often used as a nutritional supplement for water-soluble vitamins and water-soluble plant proteins. It can also be used in the production and application of fermented fertilizer.
Corn steep liquor powder is a common organic nitrogen source in microbial growth. It also promotes the biosynthesis of antibiotics, amino acids and enzymes. In the process of biological fermentation, it is used as the supplement of water-soluble plant protein and water-soluble vitamin. Although the physical and chemical indexes of corn steep liquor powder of each manufacturer are close to each other, there are obvious differences in the microbial fermentation process of corn steep liquor powder due to the different raw materials, manufacturers and production processes, which has a great impact on the quality of the finished product of corn steep liquor powder production. It is especially suitable for microbial biochemical pharmaceutical fermentation.
Fresh corn steep liquor was prepared by instant heating and spray drying at low temperature, and the dried corn steep liquor powder with good water solubility was obtained, while all characteristics of corn steep liquor were maintained. The heating method is steam heating. The product is free of impurities and coking. Corn steep liquor powder is reddish brown to light yellow. It has a unique smell. No fermentation, mildew and other odor. It dissolves rapidly and completely. In the process of biological fermentation, it can be used as a nutritional supplement of water-soluble plant protein and water-soluble vitamin.
The preparation process of corn steep liquor powder is as follows:
1. Before soaking corn, remove impurities on corn surface by air drops and water washing.
2. Remove insoluble impurities in corn soaking solution through bag filter.
3. After four times of evaporation and concentration, the filtrate Baume reached 20-22 ℃.
4. the concentrate is filtered through a bag filter and then enters the spray drying tower to dry the finished product.
5. The finished product should be packed after passing the inspection.

Corn steep liquor powder organic fertilizer is extracted from natural corn steep liquor. Its nitrogen (N), phosphorus (P), potassium (K) and other nutrients are closely combined with organic matter, highly consistent with the natural synergistic mechanism of soil and crops, providing nutrient supply for green planting.
Corn Steep Liquor Powder Organic Fertilizer: A Good Helper for Improving Soil Compaction
Corn Steep Powder is rich in nutrients. By "supplementing high-quality organic matter and activating microorganisms," it can specifically repair soil structure and fundamentally address the compaction problem.
Specifically, when the culture medium contained 5 g/L Corn Steep Liquor Liquid and 7.6 g/L sodium glutamate, the absorbance of the red pigment reached 20.7 U, compared to only 12.4 U in the control. This indicates that the addition of Corn Steep Extract significantly increased red pigment production.
Benefits of Adding Corn Steep Liquor Powder to Feed Fermentation
Adding corn steep liquor powder to feed fermentation can positively impact the fermentation process and final results in multiple ways, including nutritional supplementation, fermentation efficiency, and cost control.
Organic farm: Corn Steep Liquor Powder are promoters of tomato seedling growth
Corn steep liquor dry powder has a balanced ratio of NPK 7-7-7 and is 100% soluble in water. It is rich in up to 60% organic matter, which can transport a large amount of carbon source to the soil and effectively improve the physical and chemical properties of the soil. The protein content of Corn Steep Powder is not less than 42%, and the total amino acid content is not less than 35%. These nutrients can be directly absorbed and utilized by crops, providing sufficient nitrogen source guarantee for the growth of tomatoes.
Corn steep liquor powder has a cost advantage and more comprehensive nutrition than amino acid powder. The two can form a synergistic effect in the application of agricultural fertilizers through nutritional complementarity, fertilizer efficiency enhancement and cost optimization, which can achieve the improvement of fertilization effect and optimization of economic benefits.
