Description

 Continuous organic fertilizer manufacturing method  

The present invention relates to a method for producing a fertilizer, and more particularly to a method for producing a continuous organic fertilizer.

According to statistics, the amount of organic waste produced in Taiwan is as high as 30 million metric tons a year. This huge amount of production has caused considerable waste disposal problems. If disposed of at will, it will cause very serious environmental pollution problems. Organic waste is handled in three main ways: composting, burial, incineration, and fermentation. Among them, the low cost, safety and environmental friendliness of composting treatment is an organic waste treatment method that the government has vigorously promoted in recent years.

However, the disadvantage of traditional composting is that it takes a period of time to ferment and ripen, turning these organic wastes into organic fertilizers. During this time, depending on the temperature, water, oxygen content and other conditions, it is possible from 2-6 months to 15 days. Not only does it make it impossible to accurately grasp the production schedule, nor can it predict the degree of ripening of organic fertilizers. Moreover, the method of artificial stacking requires a considerable amount of manpower, man-hours, and requires a large space and space for stacking, and also produces an odor. Finally, the time of ripening is beyond control.

Referring to Figures 1 and 2, the continuous organic fertilizer manufacturing method provided by the present invention comprises steps S10, S20, S30 and S40.

First, in step S10, a reactant is added to a first fermentation apparatus 10 which has been preheated to 150 ° C or higher, and the reactant is heated to 70 ° C or higher, preferably 70 ° C to 90 ° C, and the reaction is about 20 to 30 minutes. The reactants include any one of farm organic waste, livestock waste, agricultural processing by-products, or industrial urban organic waste, or a mixture of the above materials. Farm organic waste, mainly agricultural crop residues, including rice bran, bagasse, rice bran, mushroom planting waste and so on. Livestock waste, including chicken, duck, goose, pig, cattle and other poultry or livestock feces, urine, treated corpses or a mixture of the above materials. Agricultural processing by-products, including blood meal, dried meat powder, fish bones or poultry containing meat bones, surimi, oil mites and so on. Organic waste in industrial cities, including feathers, bark, wood chips, sludge, kitchen waste, fruit and vegetable residues, and other household waste. By heating at high temperatures, kill more than 90% of the pathogens and 100% of the eggs and weed seeds.

Next, step S20 is to add a strain to the reactant. At the existing temperature, in the first fermentation apparatus 10, the reaction is carried out for 60 to 90 minutes, so that the strain used in the composting process is inoculated into the reactant to activate the strain. Common commercially used strains include: nitrogen-fixing strains of Rhizobium, phosphorus-dissolving bacteria, citrate bacterial species, fungi-producing fungi species, actinomycetes, mineralized and mature organic fertilizers. Wait.

When the first fermentation apparatus 10 is preheated to 150 ° C, the added reactants can be rapidly heated in step S10, and the heat energy generated by the activation of the strain during the reaction of step S20 makes the first fermentation apparatus 10 easy. During the reaction of steps S10 and S20, the reaction environment is maintained between predetermined temperatures, and the number and time of heating required in steps S10 and S20 are reduced to achieve an effective energy saving effect.

Step S30 is to move the reactants from the first fermentation apparatus 10 to a second fermentation apparatus 20 at a predetermined rate, and the second fermentation apparatus 20 turbulates the reactants and maintains the reaction temperature in the second fermentation apparatus 20. Wherein, the second fermentation device 20 is a drum type turbulent tank, and the tumbling tank adopts a heat preservation design, so that the temperature in the second fermentation device 20 can be maintained at 50 ° C to 70 ° C through the heat energy emitted by the fermentation. In order to meet the temperature of the growth of the strain, the strain is subjected to a sterilizing reaction in the reaction, and the time for performing the expansion reaction is 2 to 8 hours.

As shown in FIG. 2, during the actual operation, the reactants in the first fermentation tank 10 are moved to the second fermentation tank 20 through the first conveying device 12 between the first fermentation tank 10 and the second fermentation tank 20. The first delivery device 12 may be a screw delivery tube that aliquots or quantifies the feed in conjunction with the time required for the expansion reaction and the amount of reactant feed. In this way, the rate at which the reactants move from the first fermentation tank 10 to the second fermentation tank 20 is determined, and the rolling speed of the second fermentation tank 20 is adjusted in conjunction with the feed rate so that the reactants stay in the second fermentation tank 20 2 After 8 hours, drop from the exit in order. Further, a dynamic balance is obtained among the four variables of the amount of feed and discharge, the length and rotation speed of the second fermentation tank 20, and the residence time of the reactants in the second fermentation tank 20. For example, 300 kg of the reactants that have completed the reaction from the first fermentation apparatus 10 are sent to the second fermentation tank 20 in 100 minutes, and the feed amount per minute is 3 kg, and the length of the second fermentation tank 20 is 5 At a revolution of 3 revolutions per minute, the second fermentation unit 20 can be blanked at the same discharge rate of 3 kg per minute. Such a process, in addition to allowing the reactants to maintain the reaction temperature during the expansion reaction while conserving energy, allows the reactants to be carried out in a flowing, continuous, uninterrupted manner during the continuous fermentation.

Step S40, the reactants are put into the third fermentation device 30 from the second fermentation device 20, and the third fermentation device 30 is tumbling from the bottom to the clockwise or counterclockwise direction at a predetermined rate, so that the reactants move from the bottom to the bottom. In the process, it gradually matures and then falls out. At the time of actual operation, the reactants stay in the third fermentation tank 30 for about 7 days to carry out a ripening reaction. As shown in Fig. 2, the second fermentation device 20 and the third fermentation device 30 are connected by a second transfer device 22, and the reactant dropped at the outlet of the second fermentation device 20 is moved to the third fermentation device 30. The third fermentation device 30 may be an upright fermentation tank, and the bottom of the third fermentation device 30 is provided with a stirring device 32. The stirring device 32 rotates clockwise or counterclockwise at the center of the bottom of the third fermentation device 30. At the same time, the reactants are driven from the outside to the center of the circle, so that the reactants stacked in the third fermentation device 30 form a continuous gradient from top to bottom, and form a continuous gradient, and then the reactants are fully matured. Thereafter, it falls from the center of the bottom of the third fermentation tank 30 as shown in Fig. 3.

According to the above description, the continuous organic fertilizer manufacturing method disclosed in the present invention, in the process of composting fermentation, the various steps in the process are connected to each other, and the reactants can sequentially pass through the first fermentation device 10, the second fermentation device 20, and The third fermentation device 30 and the like are successively carried out under different reaction environments, and under the process of computer-controlled treatment of the whole process temperature, humidity and conveying speed, the reactants of various organic wastes are truly continuous, uninterrupted and flowing in the process of composting fermentation. Sexual production effects have greatly improved the efficiency of production. And can meet the requirements of the composting yard setting. The first, second and third sections of the fifth point are closed and processed, and meet the requirements of the sixth point. Through experimental tests, the continuous organic fertilizer manufacturing method disclosed in the present invention can shorten the composting fermentation process to about 8 days, and the monthly production capacity can reach 10,000 tons.

The sealed tanker 40 is used to collect and transport the goods, and then poured into the first fermentation device 10 through a third conveying device 42 to start the production of organic fertilizer, and the time and possibility that the organic waste is exposed to the outside or in contact with the outside. Minimize and achieve a clean, odor-free effect.

Referring to FIGS. 2 and 3 again, in step S60, the reactant is again introduced into the third fermentation apparatus, and step S40 is repeated. Because in the actual operation, in order to achieve the full ripening effect, the reactants that have already fallen out will be transported from the discharge point to the input by the fourth conveying device 34, and the second or more ripening reaction will be carried out. The reactants achieve the best ripening effect.

In step S70, the reactants are dropped from the third fermentation device 30 into a granulation device for granulation, or directly packaged to form a final organic fertilizer product.
