Combined far infrared fermentation equipment and method

Abstract

The invention provides combined far infrared fermentation equipment. The combined far infrared fermentation equipment comprises a high-temperature rapid sterilization, fermentation and decomposition device. The high-temperature rapid sterilization, fermentation and decomposition device comprises a bin, a driving and stirring device and a far infrared heating device, wherein the driving and stirring device comprises a stirring device arranged in the bin and a start driving device connected with the stirring device, and the far infrared heating device is matched with the stirring device. The combined far infrared fermentation equipment has the advantages of being simple in structure, convenient to operate, high in treatment efficiency, small in occupied space, low in manufacturing cost, low in time consumption, uniform in heating, capable of saving energy, environmentally friendly, wide in application range, and high in applicability and good in industrial application prospect when applied to large or medium or small raising households.

Description

technical field [0001] The invention relates to a combined far-infrared fermentation equipment and a fermentation method. Background technique [0002] The toxic and harmful substances in livestock and poultry manure are seriously beyond the capacity of the environment. If they are not treated harmlessly, it will not only cause groundwater pollution and microbial content exceeding the standard, but also pollute the air, making ammonia, sulfur dioxide and other harmful gases in the atmosphere At the same time, livestock and poultry manure will also cause soil environmental problems such as soil acidification and heavy metal residues. At present, there are several methods for the treatment of aquaculture manure, such as anaerobic fermentation (digester), composting, or direct application as fertilizer, but the existing treatment methods all have large investment, large land occupation, secondary pollution and process Control complex and other defects.

Problems solved by technology

[0002] The toxic and harmful substances in livestock and poultry manure are seriously beyond the capacity of the environment. If they are not treated harmlessly, it will not only cause groundwater pollution and microbial content exceeding the standard, but also pollute the air, making ammonia, sulfur dioxide and other harmful gases in the atmosphere At the same time, livestock and poultry manure will also cause soil environmental problems such as soil acidification and heavy metal residues

At present, there are several methods for the treatment of aquaculture manure, such as anaerobic fermentation (digester), composting, or direct application as fertilizer, but the existing treatment methods all have large investment, large land occupation, secondary pollution and process Control complex and other defects

Taking the anaerobic fermentation method and composting method as examples, the required floor area and investment are relatively large, and the temperature and humidity need to be well controlled during treatment. Not only is the process control difficult, the process steps are tedious, and the treatment time is very long (15~ 60 days), it is difficult for ordinary farmers to form a scale

On the other hand, cultured manure itself is a kind of good farmyard manure, and it is a high-quality organic fertilizer resource for fertilizing and improving the soil. However, if the manure is directly applied, it will inevitably have negative effects such as crop root damage, disease, and weed damage.

Due to the limitations of many factors, most of the farmers in our country cannot make good resource utilization of the breeding manure.

[0003] In order to simplify the operation procedure for the treatment of breeding manure and improve the process efficiency of the treatment of breeding manure, a variety of treatment equipment for breeding manure is disclosed in the prior art, but most of the existing treatment equipment is static fermentation equipment, and the structure is relatively complicated , the feed and discharge are not smooth, the fermentation time is long, and the fermentation effect is not ideal, it is difficult to meet the needs of farmers for large-scale treatment of breeding manure
