The present invention relates to a fermentation drying apparatus for producing compost for livestock feed or crop cultivation using various organic perishable wastes generated as various by-products such as agricultural, livestock and aquatic products of the present invention. Fermentation drying that is placed inside a fermentation drying room installed in a slope and maximizes uniform agitation and smooth air distribution while maintaining proper internal temperature range to minimize decay and deterioration during the drying and stirring process of waste, and to make fermentation drying more effective. Relates to a device.

In the prior art, Korean Patent Publication No. 93-1204, Patent Publication No. 93-1480, Patent Publication No. 93-2234, etc., which are the original inventions of the present inventors, are disclosed. There was a problem of deterioration due to acetic acid fermentation, or a problem of corruption due to inadequate oxygen supply, and a large amount of heat consumption during the stirring process, and energy loss problem and dust generated inside during the drying process. The air supply and discharge holes are easily blocked, and the operation of the machine and the fermentation process are not constant, causing the viscous material to stick to the interior wall of the fermentation chamber or the drying room and become solid and deteriorate, thus adversely affecting the heat transfer between the heating source and the raw materials. Problems that reduce efficiency and adherence of viscous materials to the inner wall of fermentation chamber or drying chamber These jeomjilmul the rotation of the stirring wing of the functionalized is to act as a load element had the various problems such as the central axis of the excessive load is mad mechanical surface speed.

In order to solve these problems, the present inventors install the fermentation drying barrel at an inclined angle and install a spiral downward stirring blade to allow downward movement in the center, and increase the mixed material on the outside of the downward stirring blade. Patent application No. 94-2750 filed with a spiral upward stirring blade to enable the installation, and separately installed scrapers so that the mixed material which rises or falls on the upper and lower parts is not solidified on the inner wall of the fermentation drying vessel. .

The selected technology of the present inventors minimizes the dust generated after fermentation drying, while extending the life and stirring efficiency of the device by minimizing the supply / exhaust of the air, suppressing the sticking solidification phenomenon, and minimizing the load of the stirring mechanism. However, this pre-applied technology was also used by the present inventors, and as a result, various problems were inherent.

That is, the problem of the prior application technology is that the air inlet and the air exhaust outlet are located close to each other, so that the air circulation is smoothly at first. There was no air circulation and excessive air pressure acted on one side by this action, causing hot water and cold parts to exchange, which delayed drying due to the regeneration of moisture and thus reduced fermentation. Since the upper and lower stirring blades of the central rotating shaft are constant in the apparatus, there is a lot of space on the upper side such as fermentation drying. Therefore, excessive agitation on the upper side results in excessive dust generation. Mixed materials are forced to be pulverized into fine particles Due to the low drying, moisture and fine particles gather together to make the viscous strong, resulting in saccharification (viscosity) fermentation, and finally the outer part is excessively supplied with oxygen. If this occurs, there is a problem of degradation of the device due to lumps and life of the device due to the load action.

The present invention was created to overcome the shortcomings of the source technology of the present applicant as described above, the object of the present invention is to install the intake and exhaust holes of the external air to the fermentation drying tank is installed obliquely to the maximum distance by the upper blower Maximizes the drying rate by minimizing the rehydration with less air pressure through smooth air circulation to the inside of the mixed material by adopting the forced circulation method from the lower inlet to the upper inlet even when the internal air circulation is filled with the contents (mixed material). To promote the fermentation phenomena by the air blower and adopt the indirect exhaust method to discharge the air inside the fermentation drying tank by the negative pressure generated by the exhaust blower. Minimize,

Partial air is introduced from the upper inlet connected to one side by using a negative pressure phenomenon generated inside the upper exhaust hole by forced discharge of the blower, and air pressure is applied to the steam and dust discharged to the upper inlet. It serves to provide a fermentation and drying apparatus that minimizes environmental pollution by performing a role of air curtain to shut off relatively heavy dust and settle inside and discharge purified water vapor.

Another object of the present invention is to provide a stirring mechanism installed inside the fermentation drying vessel, the number of spiral downward stirring blades installed on the central rotary shaft is less than the number of upward stirring blades, so as to push up the mixed material from the bottom to the upper portion. Relatively equalizing the downward velocity from the top to minimize the deviation of the up and down movement speed according to the upper and lower stirring to provide uniformity in the fermentation action by uniform agitation to minimize the generation of viscous material and to minimize corruption and deterioration It is to provide a fermentation drying apparatus that can be quickly fermented decomposition.

Another object of the present invention is to install a grinding movement device inside the fermentation drying chamber to continuously carry out the grinding movement regardless of the stirring speed of the material by the stirring mechanism to increase the enzyme titer (enzyme action), resulting in good heat generation and fermentation drying. It is to provide a fermentation and drying apparatus that can be made easily because it is easy to make a good dead and compost.

The first to fourth fixing rods 31, 32, 33, and 34 are fixed to the central rotation shaft 16 in a sequential orthogonal state so that the one side upward blade 17a of the upward stirring blade 17 is the one side guide support member. The other side of the upper wing (17b) is welded to the end of (30a) and wound and fixed in a spiral of 270 degree angle to one end of the first to third fixing rods (31, 32, 33), the opposite side induction It is welded to the end of the support section 30b and wound around the other end of the first and second fixing rods 31 and 32 in a spiral of 180 degrees.

In the drawings, reference numeral 40 denotes a fixed frame, 41 a material input hopper, 42 a discharge port, 43 a heat insulating material, 44 an outer casing, 45 a front opening door, 46 a rear opening door, and 47 a heater. It is.

On the basis of the accompanying drawings will be described in detail the effect of the present invention.

First of all, raw materials used in the present invention are used when slaughtered wastes such as livestock waste or blood wastes, fish residues or food wastes, by-products generated during plant processing, and various manures are mixed or united. These raw materials contain almost all of the moisture. Nitrogen compound with strong cohesiveness due to the nature of the raw material, which cannot be fermented or delayed, is difficult to fermentation, and has acidification characteristics.

In addition, such wastes do not generate heat due to lack of carbon during fermentation, and are not easily decomposed due to lack of enzymes to generate various malodorous gases as well as polluting soil or surrounding environment.

Therefore, the inventors, as described in the specification of the prior application, mix the first sub-materials made of zeolite, vermiculite or clay minerals with the raw materials to control the amount of moisture while reducing the cohesion of the raw materials and acting with various carbon sources. It can remove gas and odor, and mix the second sub material such as sawdust, chaff and the third sub material such as rice bran, bran or blended feed to obtain various enzyme raw materials, and to allow sufficient enzymatic decomposition. If necessary, conventional fermentation enzymes may be microadded to promote enzymatic degradation.

That is, as described above, the dry fermentation chamber 11a of the dry fermentation tank 11 through the material input hopper 41 using an appropriate ratio of the raw material first sub-material, second sub-material, third sub-material and, if necessary, a small amount of fermentation enzyme. ) And the water in the hot water pipe 14 by the heater 47 to be heated above the proper temperature and passed through, so that the drying fermentation chamber 11a of the drying fermentation tank 11 maintains the temperature above the proper temperature. When the drive unit 27 drives the sprocket 28, the chain 29, and the interlocking sprocket 26, the central rotation shaft 16 of the stirring mechanism 15 rotates to stir the material introduced from the drying fermentation chamber 11a. Will be mixed.

At this time, the injected material is continuously raised while mixing the inner circumferential surface of the dry fermentation chamber 11a by the spiral upward stirring blade 17, as shown in FIG. While gathering to the center of the dry fermentation chamber (11a) by the aroma stirring blade (18a) while descending due to the downward operation of the self-weight by the inclined installation of the drying fermentation cylinder (11) and the spiral downward stirring blade (18), the rotation is mixed slowly As described above again by the upper stirring blades 17 fixed to the outside by scraping while stirring to prevent the mixed material from adhering and solidifying to the inner surface of the dry fermentation chamber 11a by the induction support intervals 30a and 30b configured at the lower portion thereof. As a result of repeated processes of ascending and descending through the process, stirring and mixing are performed.

One of the core technologies of the present invention is the role of the stirring mechanism 15 as described above.

That is, in the source technology, the number of agitating blades of the up stirring blade 17 and the down stirring blade 18 was the same number without considering the inclination of the fermentation drying barrel. The material upward speed and the downward speed of the white stirring blade 18 are the downward speed of the material due to the self-weighting of the material due to the inclination, so that the material is always driven from the lower part of the fermentation drying chamber 11a so that the stirring mechanism 15 ), The shortcoming of device life and uniform stirring could not be provided.

Therefore, in the present invention in consideration of the self-weight drop of the material introduced by the inclination of the fermentation drying tank 11 while inducing stirring by the guide support (30a, 30b) in consideration of the weight of the material 270 degrees The upper portion of the upper and lower portion of the dry fermentation chamber (11a) by the helical upward wing (17a) by striking the material to raise the upper and lower by moving the spiral upward wing (17b) of the opposite side 180 degrees By moving upward at the periphery to minimize the self-weighting deviation, the material upward by the up-wings (17a, 17b) of the up stirring blade 17 is collected to some extent in the upper lower peripheral portion, forming a downward stirring blade (18) It overcomes the weight drop while raising upward by the outer downward wing (18a) of the 90 degree angle to move downward toward the center by the inner facing inner wing (18b, 18c) installed on the inner side. It will be done despite the inclination of the fermentation drying tube and provide a uniform stirring and rotational cycle of the material.

During this operation, another key technology of the present invention is the air circulation system.

That is, the gas generated in the stirring and mixing process of the material while the air is circulated to the purified material while the mixing and stirring by the operation of the blower 21 is discharged from the outside to the upper outlet 12 by the blower 21 and the blower Air is circulated through the lower suction port 13 through the material filled in the fermentation drying chamber 11a through the lower suction port 13 to be discharged to the upper discharge port 12.

In this process, the upper discharge port 12 formed by the material input surface has a lot of space, and a negative pressure is generated in the space part by the forced suction operation of the blower 21.

This negative pressure is generated in the discharge process by the forced suction input of the blower 21, so that the water and dust are generated during the stirring of the material, and the water vapor is discharged to the upper discharge port 12 through the space portion where the negative pressure is generated. The aerobic large dust falls to its own weight, and the external air is sucked by the pressure difference due to the negative pressure from the suction hole 23a of the opening 23 which is formed in front of the guide duct 19 constituting the upper discharge port 12. As the air curtain (A, C) role is provided by the pressure of the intake air to provide a function of reducing the fine dust, it is effective to discharge the relatively purified water vapor.

In particular, in the source technology, the discharge of steam to the outside of the fermentation drying chamber 11a by the blowing of the blower adopts a direct discharge decoration via the blower 21 directly so that the failure caused by the discharged steam and the fine dust contained therein is eliminated. There was a problem that occurred frequently,

In the present invention, the blower tube 22 of the blower 21 fixed to the outside is installed in the guide tube 20 communicating with the guide duct 19 constituting the upper outlet 12 (blower tube by the blower 21 ( 22) The failure rate of the blower 21 is minimized by adopting an indirect discharge method in which water vapor of the dry fermentation chamber 11a is indirectly discharged through the guide duct 19 and the guide tube 20 by the blowing force discharged to the air. It offers ease of repair work.

11 is a longitudinal cross-sectional view showing a modified example of the present invention, which is provided with a grinding mover 50 at a lower periphery of the dry fermentation chamber 11a of the dry fermentation cylinder 11 to be interlocked with the stirring mechanism 15. However, the grinding mover 50 has a spiral screw blade 52 is integrally formed on the outer surface of the interlocking side (51).

Stirring mechanism 50 of this structure is fixed to the interlocking sprocket 26 'on the central rotation shaft 16 of the stirring mechanism 15 protruding to one side of the dry fermentation cylinder 11 and to the interlocking sprocket 26' Connecting the interlocking sprocket 54 installed at the end of the interlocking shaft 51 of the agitating mechanism 50 with the chain 55 to drive the reduction motor 27 in a state in which the driving force is transmitted, the agitating mechanism 50 It is stirred by the screw blade 52 of the material is pushed toward the lower side of one side while moving to the other side, that is, while grinding in the upper direction of the drying fermentation chamber (11a) so that the material is agglomerated or viscous at the corner of the lower side The material that has been minimized and moved to the upper side is moved to the lower side through the central part again by the stirring mechanism 15 located on the upper side without overloading, so that the fermentation grinding movement and drying operation of the up, down, left and right are very fast. Easily pressed In addition, the grinding mover 50 serves to increase the enzymatic value of the material to be stirred, so that the heat is generated well and the fermentation is easily dried, thus making it easier to prepare excellent feed or compost without decay. .

As discussed above, the present invention minimizes environmental pollution by discharging purified water vapor by effective air circulation during fermentation drying process, and provides effective fermentation drying by uniform stirring of materials. In addition to minimizing the load on the agitator mechanism, it minimizes the extension of the service life and the failure rate of the blower, and also facilitates the fermentation and grinding movement very quickly and easily by the crushing mover to minimize the conventional problems such as corruption and deterioration. It is obvious that this is a very useful design.
