BACKGROUND OF THE INVENTION
  The present invention relates to a method and an apparatus for producing fertilizer and feed by boiling and ripening raw garbage, sludge and the like for use as raw material and feed for raw garbage and sludge generated from various places, and further, More specifically, the present invention relates to a method for producing fertilizer and feed by boil drying and maturation of fertilizer and feed so as not to generate a bad odor from the above-mentioned raw waste and sludge, and an apparatus therefor.
[0002]
[Prior art]
  As is well known, garbage is anaerobic fermentation that destroys the cellular structure of the garbage while giving off a bad odor, that is, primary fermentation, and then shifting from anaerobic fermentation to aerobic fermentation that does not emit bad odor. In other words, secondary fermentation is performed, and finally a healthy aerobic bacterium is ripened to decompose organic matter that is garbage. Moreover, the moisture content which shows the quantity of the water | moisture content of the said whole garbage normally is about 80%.
[0003]
  Therefore, conventionally, in order to reduce the moisture content of the garbage, a moisture adjusting material such as dry powder is mixed with the garbage. By the way, raw garbage is mainly waste dead fish, vegetables, and fruit scraps, and the internal tissue is not destroyed in these raw garbage. Even if mixed, the moisture content on the surface of the garbage is as low as 40 to 50%, but the moisture content is still about 80% inside the garbage.
[0004]
  Accordingly, the surface portion of the garbage has a moisture content of 40 to 50% and is in contact with oxygen in the air, so aerobic fermentation, that is, secondary fermentation is performed. Since the water content is still about 80%, anaerobic fermentation is performed, and the cellular structure of the garbage is destroyed, that is, primary fermentation is performed. And since the said garbage is aged in this state, it is aged gradually, giving off a bad smell.
[0005]
  On the other hand, methods for producing fertilizer and feed from the above-mentioned garbage using some devices have also been proposed. That is, the garbage is put into a cooker and boiled. Next, the boiled garbage is put into a dehydrator and dehydrated to lower the moisture content of the whole garbage. And the fertilizer and feed are manufactured by putting the garbage which the said moisture content fell into a dryer, and drying it.
[0006]
[Problems to be solved by the invention]
  According to the above conventional technique, when using a moisture adjusting material, man-hours for producing fertilizer and feed from raw garbage are small, but since the moisture adjusting material is mixed with the raw garbage, the total amount of the raw garbage is increased. . Moreover, since the anaerobic fermentation which emits a bad smell inside the said garbage is carried out during aging, the bad smell continues to be emitted.
[0007]
  On the other hand, when some devices are used, the water content of the garbage is reduced by using a dehydrator to reduce the moisture content. The manufacturing man-hour for manufacturing a feed will increase.
[0008]
  Accordingly, an object of the present invention is to solve the problems of the conventional techniques as described above, and when producing fertilizer and feed from raw garbage and sludge, malodor due to primary fermentation is generated. It is an object of the present invention to provide a method and apparatus for producing fertilizer and feed by boil drying and ripening sludge with low man-hours for producing fertilizer and feed from raw garbage and sludge.

And while the raw material A sent into the said boil drying tank 2 is stirred by stirring means 3, such as a rotary winding upper blade and a spiral rotary blade, the cell structure of the said raw material A is destroyed.WhileThe moisture of the raw material A evaporates by being pressed against the heat transfer surface 6 of the inner wall surface of the boil drying tank 2. That is, the water content of the raw material A is lowered. Thus, by lowering the water content of the raw material A while destroying the cell tissue of the raw material A, both the conventional primary fermentation and secondary fermentation can be completed. Therefore, malodor generated from the raw garbage as the raw material A by primary fermentation can be suppressed.
[0047]
  And when the moisture content of the raw material A in the said boil drying tank 2 becomes 40 to 50%, the said raw material A is sent in the rotary aging tank 41 of the said rotary aging apparatus 40. FIG. More specifically, the raw material A is passed through the lead-out pipe 10 by the lead-out screw conveyor 11 disposed in the boil drying tank 2 and through the lead-in pipe 42 connected to the lead-out pipe 10 to the rotary aging tank 41. Sent.
[0048]
  And the raw material A sent in the said rotary aging tank 41 is a thing by which a microbe is planted and ripened in the said rotary aging tank 41, when the said rotary aging tank 41 rotates with the power source which is not shown in figure. is there. Further, the rotary aging tank 41 is arranged so that the introduction pipe 42 side is located at a higher position than the outlet pipe 43 side, that is, obliquely arranged, so the raw material A in the rotary aging tank 41 is The rotary aging tank 41 is gradually aged toward the outlet pipe 43 while being aged while rotating. In addition, the said microbe can be selected freely in the air | spore, yeast, natto, wine yeast, etc. Moreover, if the soil fungus of the field used as a fertilizer is used, the influence on the plant ecosystem by the new fertilizer fungus will be lost.
[0049]
  The raw material A located on the outlet pipe 43 side disposed in the rotary aging tank 41 is then sent to the product hopper 67 through the outlet pipe 43 by the outlet screw conveyor 44 and fertilizer. The product B is a feed. Then, the product B is carried out by a transport vehicle etc. through a lead-out pipe 68 by a lead-out screw conveyor 69 operated by a power source (not shown) provided at the bottom of the product hopper 67, packed in a bag, etc. It is used as feed.

【The invention's effect】
  As described in detail above, the present invention has the following effects.
  That is, since raw materials that are boiled and aged by the boil drying and aging apparatus of the present invention and raw materials that are sludge are subjected to primary fermentation and secondary fermentation that have been conventionally performed, The raw materials which are garbage and sludge do not give off the bad smell generated by primary fermentation. In addition, since the boil drying / ripening apparatus is composed of one or two apparatuses, man-hours for producing fertilizer and feed from the raw materials can be reduced.
