Exhaust Valve Feed Fermentation Bag

1. Product introduction

In the field of feed fermentation, the fermentation bag is a common tool, and the feed fermentation bag with exhaust valve provides a lot of convenience and advantages for the fermentation process. This innovative fermentation bag can effectively solve the problem of gas emissions during fermentation, while ensuring the stability of the fermentation environment and the quality of feed.

2. Product material

Body material

The main material of the feed fermentation bag is usually high quality polyethylene (PE) or polyvinyl chloride (PVC). Polyethylene material has good flexibility, corrosion resistance and chemical stability. It can withstand a certain amount of pressure, is not easy to break, and can adapt to various external forces during the feeding and fermentation process. Polyvinyl chloride material has good gas barrier property, which is helpful to maintain the anaerobic or micro-oxygen environment in the fermentation bag.

These materials are non-toxic and odorless, ensuring no contamination of feed. When selecting the material, the safety of direct contact with the feed is also taken into account, which meets the relevant standards of food safety and ensures that the fermented feed can be safely used for livestock breeding.

Exhaust valve material

The material of the exhaust valve is generally aging and corrosion resistant plastic or rubber material. The outer part of the exhaust valve is usually a plastic that matches the main material of the fermentation bag, has good sealing and connectivity, and can be firmly installed on the fermentation bag. The internal spool part may be made of rubber or special plastic material, which has good elasticity and permeability control.

The material of the exhaust valve needs to be able to work properly under different temperature and humidity conditions. For example, in the high temperature fermentation environment, the sealing performance will not be lost because of the softening of the material; In the low temperature environment, it will not become brittle and affect the exhaust function.

3. Function and design of exhaust valve

One-way exhaust function

The exhaust valve has the characteristic of one-way exhaust. In the fermentation process, with the metabolic activities of microorganisms, carbon dioxide, methane and other gases are produced. The exhaust valve allows these gases to be discharged from the fermentation bag to the outside of the bag, while preventing outside air from entering the fermentation bag. This one-way gas flow mechanism is achieved through a special structure inside the exhaust valve.

For example, the spool inside the exhaust valve will be pushed open when the pressure inside the bag is higher than the external pressure, and the gas can be discharged; When the pressure in the bag is reduced or the external pressure is higher than the pressure in the bag, the spool will close to prevent air from entering. This ensures that a suitable fermentation environment is always maintained in the fermentation bag, which is conducive to the growth and reproduction of beneficial microorganisms.

Precise pressure control

The exhaust valve provides precise control of the pressure in the fermentation bag. It can perform exhaust operations according to a set pressure threshold. In general, when the pressure in the bag reaches a certain degree (usually about 1-2 kpa, the specific value can be adjusted according to the fermentation requirements), the exhaust valve begins to work. This precise pressure control helps maintain the stability of the fermentation process.

If the pressure in the bag is too high, it may cause the fermentation bag to break; The pressure is too low, which may mean that the fermentation environment is not ideal, such as insufficient anaerobic degree. By adjusting the pressure, the exhaust valve keeps the gas composition, humidity and other environmental factors in the fermentation bag within a range conducive to fermentation.

Anti-clogging design

The exhaust valve is also designed to prevent clogging. During the fermentation process, some small particles in the feed or substances produced by microbial metabolism may block the exhaust channel. The exhaust valve uses a large ventilation aperture or a special anti-clogging structure, such as a filter screen around the vent or a slanted ventilation channel, so that impurities are not easy to accumulate in the exhaust valve to ensure that the exhaust valve can continue to work normally.

4. Ease of use

Easy to fill: the opening design of the feed fermentation bag of the exhaust valve is large, which is convenient to fill the feed. It is easy to fill either manually or mechanically. For manual loading, the chopped feed raw materials can be directly poured into the bag; For mechanical loading, the large opening can be well matched with the loading equipment to improve the loading efficiency.

During the loading process, no particularly complex operation is required to avoid the exhaust valve, because the location of the exhaust valve is usually properly designed and does not hinder the loading.

Observation and monitoring

The presence of the exhaust valve facilitates the observation and monitoring of the fermentation process. By observing the exhaust of the exhaust valve, the progress of fermentation can be preliminarily judged. For example, if the exhaust is frequent and the amount of gas is large, it may indicate that the fermentation is in a prosperous period; If the exhaust gradually decreases, it may indicate that fermentation is nearing its end.

At the same time, some advanced exhaust valve feed fermentation bags can also be connected with monitoring equipment, real-time monitoring of the pressure, temperature and other parameters in the bag, to further improve the control ability of the fermentation process.
