Is it necessary to ventilate the open fermentation bed housing?
The fermentation bed culture technology has the effects of deodorization, environmental protection, energy saving, grain saving, water saving, labor saving, disease resistance and longevity, and improved egg quality. In particular, the Tycoon Dry Fermentation Bed is operated dryly, and the litter does not need to be fermented in advance, nor is it necessary to add water and nutrient solution, and the operation is simpler and more convenient. It has been welcomed by many farmers. However, some farmers tend to have a wrong understanding: As long as skylights, underground windows, doors and windows are open in the pens, ventilation in the pens is very good. Ventilation in open style pens is better. In fact, this is the case. ?
The picture above is provided by the demonstration households of the Golden Duck Dry Sausage Duck. It can be seen from the figure that this is not the case. Ventilation of the open-style fermentation bed is not necessarily good, especially in the hot summer and in the absence of wind, natural ventilation is not enough. Experienced farmers should know that the main function of the sunroof is to complete the exchange of gas and heat inside and outside the house through the air up and down, cold and hot convection. Discharge gas with lighter molecular weight and higher temperature, such as ammonia, etc.; Windows: The main function is to discharge exhaust gas and excess heat by strengthening the air flow on the surface of the fermentation bed. Mainly to discharge larger molecular weight gases such as: carbon dioxide, hydrogen sulfide, etc.; doors and windows: The main role is to conduct regular ventilation, to maintain the relative circulation of air inside and outside the house, you can use natural horizontal wind to emit carbon dioxide, water vapor and other gases and excess heat. However, the role played by skylights, windows, doors, and windows in the absence of wind will drop a lot, even if the open-type houses are not well ventilated in the absence of wind. Therefore, additional ventilation equipment is required to promote continuous ventilation into the housing to remove heat, moisture, dust, and exhaust gas from the housing.
Fermentation of the fermentation bed is an oxygen-consuming process. If the long-term ventilating and ventilation in the housing is poor, microbial activity will be inhibited. This will directly affect the vitality of strains and the moisture and temperature of the housing, eventually leading to failure of the fermentation bed. . Therefore, the fermentation bed housing must be continuously ventilated in order to facilitate better operation of the Fermentation Bed. In order to save the cost, you can strengthen the ventilation of the house according to the above figure. Put a simple fan every 20 meters inside the fermentation bed housing. This simple fan can be made by yourself or it can be purchased. It is simple and cheap, and this A simple fan can also adjust the angle, so that all directions can be ventilated ventilation, reducing the temperature of the house, so that the air in the housing more fresh. Conditional users can also install a cooling fan. The sunroof is best equipped with unpowered sunroof and powered sunroof combined to meet the ventilation requirements under any circumstances. In addition, water curtains can be installed in summer to reduce the temperature of the house more effectively.
