摘要： PROBLEM TO BE SOLVED: To prevent the clogging of a fermentation bed of a piping, a deodorizer or a dehumidifier caused by suction, to reduce the frequency of the action removing the sucked fermentation bed and to reduce maintenance cost. SOLUTION: A cyclone 16 and a dust discharge port 17 having an opening/ closing means 18 arranged thereto are arranged to the upper part of a fermentation tank 1 between an air exhaust port 13 and a deodorizing means 14. Since the fermentation bed 4 becomes easy to scatter into the fermentation tank 1 when the water content of the fermentation bed 4 is below 20 wt.%, the opening/closing means 18 is closed and the cyclone 16 is operated to collect the fermentation bed 4.

摘要： PROBLEM TO BE SOLVED: To provide a garbage disposal device capable of reducing the load on a driving section and reducing electric power consumption i.e. a running cost while maintaining a crushing ability. SOLUTION: The garbage disposal device constituted to compost the garbage by mixing the same with a fermentation bed 4 including aerobic bacteria is provided with stationary blades 9 facing downward at the apex of the inside wall of a fermentation tank 1 or is provided with the same to face horizontal on the side walls. The stationary blades are positioned upper than the bottom end of a compost discharge port when the flanks of the fermentation tank are provided with the stationary blades. As a result, the force necessary for crushing is applied on the neck part of agitating arms 5 and, therefore, the agitating torque applied on a driving means 7 is small. In addition, not the fermentation bed 4 in the compressed fermentation tank 1 but the fermentation bed 4 in the upper part where the void volume is high is crushed and, therefore, the agitating torque may be reduced.

摘要： PROBLEM TO BE SOLVED: To obtain a fast fermentation rate and to decrease the cost to produce a compost from a biological solid org. waste by aerobic solid fermentation method by adding a low molecular accelerating factor for microbes during the fermentation proceeds. SOLUTION: A mixture of a primary fermented compost of a biological solid org. waste and a secondary fermented compost as seeds, or a mixture of a primary fermented compost of a biological solid org. waste, a biological solid org. waste and a secondary fermented compost as seeds is heaped to obtain a bed, through which an oxygencontg. gas is permeated to effect aerobic solid fermentation. During fermentation, the lower layer of the bed is withdrawn and returned as the uppermost layer of the bed, while a low molecular accelerating factor for microbial growth or a low molecular accelerating factor for microbial growth and an ash produced from one or more kinds of compost, microbial sludge, paper and plants is added to effect fermentation to obtain a compost. As for the low molecular accelerating factor for microbial growth, thiamine, riboflavin, pantothenic acid. nicotinic acid, inositol can be used.

摘要： PROBLEM TO BE SOLVED: To obtain good quality compost having a high decomposition rate by inhibiting the transfer of undecomposed matter to the downstream side. SOLUTION: In this equipment, the inside of a fermenter 1 is divided into plural sections and a material under fermentation is transferred to a final section on the downstream side of the fermenter 1 through the other sections while successively overflowing them. At this time, the transfer rate of the material under fermentation to the downstream side is controlled by detecting the weight and volume of compost in the fermenter 1, the feed rate of organic waste and the load of a driving means 13, to control the rotational direction, rotational speed and operating time of an agitation means. Since the residence time required for fermentation can be secured even at the time of causing any change in load or in waste quality, good quality compost that is dry, granular and easily handleable can be obtained.

摘要： PURPOSE:To mass produce granular gel with small particle diameters without causing clogging, etc., by setting an upper and a lower rotators of two stages and a mold susension feed nozzle at specific positions in a container in which a gel curing solution is put. CONSTITUTION:A gel curing solution is put in a container to a position where the liquid level is brought into contact with the lower rotator 4 and the nozzle 9 to feed both a suspension of a marine alga gel solution and a mold is set above the upper rotator 5. Liquid drop gel dispersed by the rotator 5 is incorporated with the surface liquid flow 19 of the gel curing solution produced by the rotator 4. Granular gel is successively produced without retaining the gel on the liquid level of the gel curing solution and the particle diameter of the granular gel can be controlled by regulating the numbers of revolutions of the rotators.

摘要： PURPOSE:To prevent the breakage of immobilized gelatinous material in a bioreactor by mechanical shock, by controlling the air flow according to the state of the immobilized particles and the flowing state of the reaction liquid in a suspension reaction column. CONSTITUTION:The kinetic pressure generated by the flow of the suspension in an immobilized enzyme suspension reactor 4 is detected by the pressure sensor 8. The flow of air supplied to the reactor 4 is adjusted by the regulator 9 according to the signal S1 of the sensor 8, and the control valve 10 is operated by the signal S2 to control the air flow through the pipe 24. The air flow necessary for the fluidization of the suspension can be controlled to a level to keep the immobilized material from breakage even if the immobilized material is filled in the reactor 4 in high concentration.
