Fertilizer starter (control of ventilation in fertilizer fermentation)

Fertilizer starter (control of ventilation in fertilizer fermentation)
In the process of treating livestock manure and other organic wastes as bio-organic fertilizer with the use of a goldfish fermentation agent, an aerobic fermentation method is adopted, which requires a certain amount of ventilation and ventilation frequency. Ventilation and oxygen supply is one of the basic conditions for the production of aerobic fermentation bio-organic fertilizer. Ventilation volume is mainly determined by the compost raw material organic content, volatility, and degradable coefficient. The main role of ventilation is: 1 to provide oxygen to accelerate the fermentation process of microorganisms; 2 to adjust the stack temperature; 3 to dry the stack. Too little ventilation will not provide sufficient oxygen to the microorganisms, which will affect the increase of the composting temperature. Excessive ventilation volume may dissipate the heat of the compost heap, affecting the compost innocuousness. The empirical data for compulsory forced ventilation is usually 0.05 to 0.2 m3/m3 of stacking material min.
Ventilation of the control mainly through the following ways to achieve: 1 natural ventilation oxygen; 2 into the reactor into the ventilation pipe; 3 use a variety of special tipping machine to turn the stack ventilation; 4 fan forced ventilation for oxygen.

Our Plastic Pipette includes serological pipette and disposable Transfer Pipette


The serological pipette(Pipette Tip) is made of imported high quality polystyrene. Novel aspiration area design can fit most of the pipettors on the market. Mainly used for accurate measure or transfer certain volume liquid and is widely employed in the field of cell cuture, bacteriology, clinical research, etc. Six capacity 1ml, 2ml, 5ml, 10ml, 25ml and 50ml are available. 


The disposable transfer pipette is made of superior LDPE material, non-toxic, adapted to draw, transfer or carry for small volume liquid. The soft material make the pipette can be bent with a certain angle, which is convenient for drawing or adding liquid in irregular or micro container. Individual pack or bulk pack are available.
