Fig. 1 shows a plan view of the culture device. The livestock manure storage tank (1) collects and stores manure from chickens, cows, pigs, etc. from producers, and sludge is accumulated from sewage treatment plants, and cellulose is collected. A crushed product, that is, crushed agricultural waste such as sugar cane is mixed with livestock excrement. Livestock manure, sewage treatment waste and cellulose are the best sources of nitrogen-fixing bacteria Azotobacter and cellulolytic bacteria Turkey Derma, and processed coral reef powder is collected and stored in the coral reef storage tank (16). It is sent to the livestock excrement storage tank (1) by a screw conveyor (S-1) attached to the lower part of 16). When mixing coral reef, the mixing ratio should be such that it has the most suitable components for the reproduction of Azotobacter, etc., which is 30 ± 10% of livestock manure and sewage treatment waste, cellulose. Crushed product 10 ± 5%, Coral leaf powder 60 ± 20%
And agitate and mix them. in this way,
The culture medium adjusted for symbiotic bacteria etc. is stored in the tank (1), and the sufficiently mixed mixture is supplied to the steam pressure cooker (11) by the screw conveyor (S-2) attached below the tank (1). -Sent to A). Steam pressure cooker (11-
In A), pressure steam is sent from the steam pressure boiler (7) through a conduit to which a steam pipe (48) is attached as shown in the piping flow sheet shown in FIG.
The vapor pressure is 9 to 12 kg / cm ² and the rapid compression method
Use a powerful steam cooker that can shorten the cooking time by the cellulosic (vegetable fibrin) blasting method. The mixture of livestock manure, sewage treatment products, cellulose, etc., which has been sufficiently cooked and sterilized in the pressure cooker (11-A), is sent to the temperature adjustment tank (11-B) installed below the steam pressure cooker. , The refrigerator (42-A), the cold air compressor (12-
B), the cooled air from the air filter (12-C) is blown from the pipe (58) so that the temperature inside the tank is adjusted to 25-35 ° C, which is the optimum temperature for bacterial culture, and the inoculum added tank (11-C). Sent to. As shown in FIG. 3, 6 kinds of the above-mentioned co-cultivated bacterial species are cultivated in the inoculum addition tank (11-C) in the inoculum culture tank (6), and the inoculum solution is fed through the pipe (55). . Further, as shown in FIG. 2, the fermented mixture fermented in the multi-tank fermenter is circulated from the fermented material accumulation tank (15) by the screw conveyor (S-9) as an inoculum aid.
