Soybean Meal Fermentation Bag

1. Product introduction

Soybean meal is a kind of high protein feed made from soybean, which is widely used in aquaculture. However, traditional soybean meal often has certain limitations in storage and use, such as being susceptible to moisture, mold, etc., resulting in nutrient loss and economic losses. In order to solve these problems, soybean meal fermentation bag came into being. Soybean meal fermentation bag is a kind of soybean meal mixed with specific microbial strains, nutritional additives and water, closed in a special bag for fermentation products. By controlling the fermentation environment, the growth and reproduction of microorganisms are promoted, so as to improve the nutritional value and storage stability of soybean meal. Soybean meal bags are usually made of multi-layer materials, the outer layer is made of plastic or fiber material with good air permeability, and the inner layer is moisture-proof and heat-insulating material. The fermentation bag is provided with a vent, which can adjust the gas and water generated during the fermentation process to avoid the environment in the bag is too wet or hypoxia.

2. Production process of soybean meal fermentation bag

Raw material preparation: Select high-quality soybeans, and obtain high-quality soybean meal after cleaning, soaking, cooking and pressing. The moisture content of soybean meal should be controlled below 10% to facilitate subsequent fermentation treatment.

Add microbial strains: According to the nutrients required for fermentation, select the appropriate microbial strains, such as lactic acid bacteria, yeast, etc. These strains can play a role in promoting fermentation, improving taste and increasing nutritional value in the fermentation process.

Mixing and stirring: the soybean meal, microbial strains and appropriate amount of water mixed evenly, stirring until no particles. At this time, some nutritional additives can be added as needed, such as vitamins, minerals, etc., to further enhance the nutritional value of the feed.

Bagging and sealing: Put the mixed soybean meal fermentation material into a special fermentation bag, taking care not to exceed the capacity of the bag, leaving appropriate space for the generation of fermentation gas. Then seal the mouth of the bag to prevent outside air from entering.

Fermentation process: The sealed fermentation bag is placed in a suitable fermentation environment, usually controlled at a temperature of 30 ° C ~40 ° C, and the appropriate humidity is maintained. The fermentation time is usually 5 to 10 days, depending on different strains and environmental conditions.

Finished product inspection: After the fermentation is completed, the soybean meal fermentation bag is inspected, including smell, color, pH value and nutritional composition, to ensure that the quality of the product meets the standard.

3. Application field of soybean meal fermentation bag

Aquaculture: The application of soybean meal fermentation bag in the aquaculture industry is particularly significant, and the nutrients of fermented soybean meal are more easily absorbed by animals, improve the conversion rate of feed, and promote the growth and health of animals.

Aquaculture: In aquaculture, soybean meal fermentation bag can be used as feed for fish and shrimp, after fermentation can effectively improve the solubility of feed and reduce ammonia nitrogen in water, reduce water pollution.

Organic fertilizer: The fermented soybean meal can also be used as an organic fertilizer for agricultural production, which can effectively improve soil fertility and promote crop growth.

4. Advantages of soybean meal fermentation bag

Improve nutritional value: After fermentation of soybean meal, its protein digestibility and utilization rate are significantly improved, which can better meet the growth needs of animals.

Enhance disease resistance: The beneficial microorganisms and their metabolites produced during the fermentation process can enhance the immunity of animals, improve their resistance, and reduce the incidence of disease.

Environmental protection and sustainable development: The use of soybean meal fermentation bags can reduce feed waste, while effectively reducing environmental pollution in the breeding process, to achieve sustainable development.

Easy storage and transportation: The sealing and moisture-proof properties of the soybean meal fermentation bag make the fermented soybean meal easier to store and transport, reducing logistics costs.

5. FAQ

What is soybean meal fermentation bag?

Soybean meal fermentation bag is a bag specially used for soybean meal fermentation, providing a closed or semi-closed space for soybean meal fermentation, in order to facilitate the growth and reproduction of microorganisms, transforming soybean meal into more nutritious and functional products.

What are soybean meal bags usually made of?

It is generally made of plastic materials such as polyethylene (PE). These materials have good flexibility, tightness, and are non-toxic and harmless, which can ensure the safety and stability of the fermentation process.

Why is soybean meal fermented?

Fermentation can improve the nutritional value of soybean meal, such as increasing the content of small peptides, reducing the content of anti-nutritional factors (such as trypsin inhibitors, etc.), but also improve the palatability and digestibility of soybean meal, making it more suitable for animal consumption.

How long does it take to ferment in a soybean meal fermentation bag?

It usually takes 3-7 days, but the specific time is affected by a number of factors, including the fermentation temperature (the ideal temperature is generally between 20-35 °C), the type and number of microorganisms inoculated, and the initial water content of the soybean meal.

How are soybean meal bags sealed?

Common sealing methods are zipper sealing and heat sealing. Zipper seal is easy to fill and check the fermentation process; The heat seal provides a tighter seal and effectively prevents air from entering.

What happens to the gases produced during fermentation?

Some fermentation bags are equipped with exhaust valves, which can automatically discharge the gas generated by fermentation (such as carbon dioxide, etc.); If there is no exhaust valve, you need to open the bag regularly to exhaust, but to minimize the entry of outside air.

What effect does bad sealing have on soybean meal fermentation?

Poor sealing will lead to a large amount of outside air entering, destroying the anaerobic or micro-oxygen environment required for fermentation, which may cause harmful microorganisms to breed, such as mold, thus affecting the fermentation effect and reducing the quality of soybean meal.

How to put soybean meal into fermentation bag?

The soybean meal after pretreatment (such as adjusting the water content, crushing, etc.) is directly poured into the fermentation bag, and attention should be paid to avoid soybean meal sticking to the mouth of the bag when filling, so as not to affect the sealing.

Can fermentation bags be reused?

If cleaned and undamaged, some soybean meal bags can be reused, but the tightness should be checked before each use.
