Analyze the basic needs of biogas fermentation

Biogas fermentation is a type of fermentation where the fermentation environment and conditions are more stringent in the crop fermentation. The following Xiao Bian will carefully analyze the basic requirements for the biogas fermentation of Jinbao:

1. Suitable fermentation temperature

Digester's temperature conditions are divided into: 1 normal temperature fermentation (also known as low-temperature fermentation) 10 °C ~ 30 °C, in this temperature conditions, gas production rate can be 0.15 ~ 0.3 m3/m3 · d. 2 Medium temperature fermentation 30°C~45°C, under this temperature condition, the gas production rate of the pool capacity can reach about 1m3/m3·d. 3 High-temperature fermentation 45 °C ~ 60 °C, in this temperature condition, the gas capacity of the pool capacity up to 2 ~ 2.5 m3/m3 · d about. The most economical temperature condition for the biogas fermentation is 35°C, ie medium temperature fermentation.

2. Suitable pH (pH)

The suitable pH for biogas fermentation is pH=6.5-7.5. The pH affects the activity of the enzyme and therefore affects the fermentation rate.

3. Appropriate dry matter concentration

Biogas bacteria do not only have to “eat” but also “drink”. Biogas bacteria need enough water during growth, development and reproduction. Water is an important part of biogas bacteria. The fermentation of organic matter in biogas digesters must be done with moderate amounts of water. If the water content of the fermentation material liquid is too small, the fermentation raw material is too much, the concentration of the fermentation liquid is too large, and the methanogen can not “eat” so much, it will easily cause a large accumulation of organic acids, which is not conducive to the growth and reproduction of the biogas bacteria. It will hinder the fermentation and it will also cause difficulties in stirring. If there is too much water, the fermentation broth is too thin, the organic content in the unit volume is small, and the gas production is small, which is not conducive to the full utilization of the biogas digester. Therefore, the digester must maintain a certain dry matter concentration. According to many years of practice, rural household biogas digesters generally require a dry matter concentration of 6% to 12% of the raw material for fermentation. Within this range, the initial concentration of biogas digesters is lower, which is easier to start. In summer and early autumn, the temperature of the pool is high, and the decomposition of raw materials is fast. The concentration may be lower, generally 6% to 8%. In winter and early spring, the temperature of the pool is low, and the decomposition of raw materials is slow. The dry matter concentration should be maintained at 10% to 12%.

4. A sufficient amount of bacteria

The number of strains in the biogas fermentation, the quality of the direct impact on the quality and quality of biogas. It is generally required to reach 10-30% of the total amount of fermentation liquor in order to ensure normal startup and strong gas production. At the same time, with the combination of Gambo Biogas Fermentation Auxiliaries, it is possible to increase the activity of the strains in the biogas, so that the strains can greatly increase the fermentation efficiency, and then increase the biogas production.

Automatic Massage Foot Bath Machine

The automatic massage foot bath machine is a device that uses water and massage rollers to provide a relaxing foot massage. It usually has a basin filled with water and has built-in massage rollers that move and massage the feet. The machine may also have other functions, such as heat therapy, air bubbles, and vibration. Users place their feet in the basin and the machine provides a soothing massage that helps relieve tension and improve foot circulation. Some automatic foot massage machines also come with removable attachments for additional massage options.
