Description

The present invention relates to a pulverizing and stirring device that finely pulverizes and agitates organic waste as a raw material for livestock feed.

Conventionally, in meat processing facilities that process meat, fish processing facilities that process seafood, and facilities that process confectionery and various foodstuffs, a large amount of food processing residue remains after processing. On the other hand, food and beverage facilities such as hotels and restaurants, and food processing facilities that process food for schools and companies also handle a large amount of food every day to serve various dishes, so kitchens that cook these foods. A large amount of "food waste" such as food waste left after cooking and leftover food left by customers is discharged from the restaurant.

Generally, food processing residues discarded from these food processing facilities and kitchen waste (organic waste) discharged from kitchens are outsourced to a specialized disposal company and are mainly incinerated. There are many. However, since this processing residue and the like contain a large amount of various nutrients, these nutrients are regarded as useful resources that can be reused, and are subjected to treatments such as stirring, crushing, drying, and fermentation for livestock animals. A system for producing feed and compost raw materials (Patent Document 1) and a system for recycling the solid content of kitchen waste into organic compost (Patent Document 2) have been proposed and put into practical use.

The processing residue and the like were discharged in a state in which animal materials such as meat waste, fish waste, and vegetable waste and vegetable materials were mixed. As a result, unlike the food processing residue discharged from the food processing facility described above, it was not composed of a single food material, and the constituent components were often different each time it was discharged.

However, in the conventional crushing and stirring device, it is difficult to crush and stir the mixed relatively soft residue and the relatively hard residue in the same device, so that the relatively hard residue is pulverized. When the designed crushing blade was used, it was difficult to crush the soft residue such as leftover food and noodles because it had stickiness. On the other hand, when a crushing blade designed to pulverize a soft residue is used, it becomes difficult to pulverize a relatively hard residue. Therefore, there is a problem that a long time is required to pulverize the soft residue and the hard residue at the same time.

Further, for example, the crushing and stirring device shown in Patent Document 2 is configured such that the kitchen waste is installed directly under the sink and is subjected to the work by the grip cutting, crushing, and dehydration separation functions in a sealed state. Therefore, the configuration is complicated, and there is a problem that causes an increase in cost. Further, since the crushing blade portion is arranged inside the cutting and crushing apparatus, there is a problem that it is difficult to remove the pulverized residue from the inside of the apparatus because the pulverized residue is entangled with the blade portion.

The problem to be solved by the present invention is that organic waste, which is a raw material for livestock feed, can be finely crushed and agitated in a short time, and crushing can facilitate the storage and discharge of the raw material. It is an object of the present invention to provide a stirrer, and an object of the present invention is to provide a method for producing livestock feed, which can uniformly spread fermented yeast by adding fermented yeast to organic waste, crushing and stirring the mixture.

Therefore, the livestock feed crushing and stirring device according to the present invention includes a cup-shaped container for accommodating raw materials for livestock feed, a lid attached so as to seal the open end of the container, and the lid. comprising a rotary blade rotatably disposed on the container side, and a drive motor for rotating the rotary blade, and a reversing means for vertically inverting the lid body in a united state of being attached to the open end of said container, said The reversing means are a guide plate having guide grooves provided on the left and right sides of the support, a reversing drive wheel provided on both sides in the radial direction near the opening end of the container, and a lid diameter. The lid is provided with protrusions provided on both sides in the direction and movably inserted into the guide groove, and the lid guides the protrusion to the guide groove and moves from the retracted position to the open end of the container. The lid body is attached to the container, and from this combined state, the projecting shaft of the lid body is guided by the guide groove to rotate around the support shaft of the container, and the container and the lid body are rotated by the reversing means. Is configured to rotate and drive the rotary blade in a state where the rotary blade is turned upside down.

Further, on the lid, a rotary blade is rotatably arranged on the container side, the drive motor is arranged on the opposite side of the container side, and the rotary shaft of the drive motor is connected to the rotary blade. Is desirable.

According to the crushing and stirring device for livestock feed according to the present invention, the rotary blade is rotationally driven by turning upside down in a combined state in which a lid with a rotary blade is attached to the open end of a container containing raw materials for livestock feed. Since the raw material is always lowered to the rotary blade side, the raw material can be pulverized and stirred quickly and in a short time. At this time, even if the raw material is a soft residue having stickiness such as leftover food or noodles, the rotary blade is directly crushed by descending, so that the crushing and stirring can be performed uniformly together with other residues.

Further, when the raw material for livestock feed is put into and discharged from the container, the opening side faces upward, which facilitates the work, and by turning it upside down, the crushed and agitated raw material is transferred from the rotary blade to the container. Since it falls inward, the residue adhering to the rotary blade can be reduced. Further, since the rotary blade is separated from the container by separating the lid body, post-treatment such as cleaning becomes easy, and workability can be further improved. On the other hand, since the lid is guided by the guide groove formed in the guide plate to move the opening end and the retracting position of the container, it is easy to put in and out the raw material to be put into the container, and the rotary blade is arranged. The heavy lid can be easily attached and detached. Further, since the container and the lid are guided to the guide groove and rotated in the reverse direction in the combined state, the work can be facilitated.

The livestock feed crushing and stirring device is rotatable toward the container side of a cup-shaped container containing raw materials for livestock feed, a lid attached so as to seal the open end of the container, and the lid body. The container is provided with a rotary blade arranged in a container, a drive motor for rotationally driving the rotary blade, and a reversing means for flipping the lid upside down in a combined state attached to the opening end of the container. The rotary blade is rotationally driven in a state where the lid is turned upside down.

Further, in the method for producing livestock feed, after accommodating a raw material for livestock feed with the opening side of the cup-shaped container facing upward, a lid is attached to the open end of the container and sealed, and the above is described. The rotary blade arranged on the lid is arranged in the container, and the lid is turned upside down by the reversing means in a united state in which the lid is attached to the open end of the container, and then the rotary blade is rotationally driven by a drive motor. The raw material is crushed and stirred, and then the lid is separated from the container with the opening side of the container facing upward again by the reversing means, and the crushed and stirred livestock feed is discharged from the container. There is.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. 1 and 2 show an embodiment of a pulverizing and stirring device for livestock feed.

The pulverizing and stirring device is composed of a container 1 and a lid 2 on which a rotary blade 3 is arranged. The container 1 is made of a metal such as a stainless steel plate or an iron plate, or plastic as a material, and is formed in a cylindrical cup shape. The lower bottom is formed in a substantially hemispherical shape, and the upper end is formed.

The lid 2 is formed in a substantially disk shape, and the outer diameter is substantially equal to the size of the open end of the container 1. A rotary blade 3 is rotatably arranged in the center of one surface side of the lid 2, and a drive motor 4 for rotationally driving the rotary blade 3 is attached to the other surface side. The output shaft 4a of the drive motor 4 extends to one side of the lid 2, and a rotary blade 3 is attached to the tip thereof. Then, as shown in FIG. 1, when the lid 2 is attached to the open end of the container 1 and sealed, the rotary blade 3 is arranged inside the container 1. It is desirable that the output shaft 4a is supported by a bearing provided in the center of the lid 2. A protective cover 5 is covered on the other surface side of the lid 2 so as to cover the drive motor 4.

When the lid 2 is attached to the open end of the container 1, an elastic packing, for example, is interposed between the peripheral edge of the lid 2 and the flange of the open end of the container 1, and the raw material described later leaks to the outside. It is desirable not to. Further, as a means for fixing the open end of the container 1 and the lid body 2, a well-known fixing mechanism is appropriately used.

As shown in FIGS. 1 and 2, the rotary blade 3 is composed of a substantially plate-shaped upper cutter 3a and a substantially plate-shaped lower cutter 3b. The upper cutter 3a is a substantially plate-like shape in which both ends of a long and thin metal plate are gradually narrowed and bent diagonally upward and outward, and the cross section on the tip side is formed in a substantially V shape and is symmetrical. It is formed in the shape of a rotating blade. By forming the rotary blade 3 in this way, the raw material described later is pushed up toward the inner wall of the container 1 by the slope on the tip side having a substantially V shape as shown by the arrow in FIG. 1, and is pushed up from the vicinity of the center. It flows so as to fall near the center of the upper cutter 3a. Then, the raw material is crushed mainly on the slope on the tip side and the blade portion by the centrifugal force of the upper cutter 3a, and the lowered raw material is crushed by the lower cutter 3b. At that time, the rotation of the upper cutter 3a and the lower cutter 3b causes the raw material to flow as shown by the arrow in FIG. 1, so that the raw material is evenly and uniformly agitated.

3 to 5 show a first embodiment as an inversion means for upside down in a combined state in which the lid 2 is attached to the open end of the container 1 in the pulverizing and stirring device. As shown in FIG. 3, the support base 10 is formed on the bottom plate 10a by, for example, four columns 10b and the top plate 10c in a substantially cubic shape. The upper plate 10c is formed with an opening larger than the outer diameter of the opening end of the container 1. Guide plates 11 are provided on the left and right on the upper side of the support base 10, and a guide groove 11a is formed in the guide plate 11.

On the other hand, in the vicinity of the opening end of the container 1 described above, support shafts 1a are provided on both sides in the radial direction, and are rotatably supported by bearings provided under the left and right guide plates 11. Further, the support shaft 1a protrudes from the guide plate 11, and a reversing drive wheel 12 is provided at the tip thereof. A motor (not shown) is connected to the reversing drive wheel 12 via a reduction mechanism. Further, protrusion shafts 2a are provided on both sides of the lid 2 in the radial direction, and are movably inserted into the guide groove 11a.

Next, the operation of the above-mentioned crushing and stirring device and the method for producing livestock feed according to the present invention will be described with reference to the first embodiment of the crushing and stirring device shown in FIGS. 3 to 5. First, as shown in FIG. 3, the raw material M for livestock feed is put into the container 1 with the opening side of the cup-shaped container 1 facing upward. This raw material M differs depending on the type of livestock, but here, pig feed will be described as an example. The raw material M for pig feed is mainly organic waste such as food processing residue discarded from food processing facilities and the like and waste discharged from kitchens and the like. However, waste containing harmful germs and slightly rotten kitchen waste are removed.

At this time, in order to ferment the raw material M of the livestock feed together with the raw material M, for example, fermented yeast E composed of Saccharomyces cerevisiae Kakegawa strain is put into the container 1 and added. In addition to this, the fermentation yeast E may be other yeast, lactic acid bacteria, or the like.

When the raw material M is put into the container 1, the protruding shaft 2a of the lid 2 is located at the right end of the guide groove 11a as shown in FIG. 3, and the lid 2 is retracted. In this retracted state, the rotary blade 3 rotatably arranged on the lid 2 faces downward of the lid 2. Then, after the raw material M and the fermented yeast E are put into the container 1, the lid 2 is moved to the position shown in FIG. Since the lid 2 moves while the protrusion 2a is guided by the guide groove 11a, the lid 2 is attached to the open end of the container 1 when the protrusion 2a reaches the bent portion at the center of the guide groove 11a. It is sealed at the same time. At this time, the rotary blade 3 arranged on the lid 2 is arranged in the container 1. As a result, the lid body 2 is attached to the open end of the container 1 and is in a united state.

After that, when the reversing drive wheel 12 is rotated to the right in the drawing by a motor (not shown) or manually, the lid 2 is rotated to the right around the support shaft 1a of the container 1 and the lid 2 combined with the container 1 is on the right. Rotate in the direction. This rotation is performed until the protruding shaft 2a of the lid 2 is guided by the guide groove 11a and eventually reaches the lowermost end and stops, and this stop position is 180 ° between the combined lid 2 and the container 1. It will be in an inverted state. When the radius from the center of the support shaft 1a of the semicircular guide groove 11a formed on the lower side is set to the dimension to be mounted so that the lid 2 is slightly pressed against the opening end of the container 1, FIG. From the state shown in FIG. 5 to the inverted position shown in FIG. 5, the state in which the open end of the container 1 is sealed by the lid 2 can be maintained. It is desirable that the protruding shaft 2a of the lid 2 is locked to the guide plate 11 by a well-known fixing means so that the lid 2 does not rotate and move in the opposite direction when the inverted position shown in FIG. 5 is reached.

In this way, when the rotary blade 3 is rotated by the drive motor 4 after reaching the reversal position shown in FIG. 5, the raw material M and the fermented yeast E contained in the container 1 are moved up as shown in FIG. 1 described above. The rotation of the rotary blade 3 including the cutter 3a and the lower cutter 3b causes the raw material M to flow as shown by the arrow in FIG. 1, so that the raw material M is evenly and uniformly stirred. At this time, the rotation speed of the rotary blade 3 is set to an appropriate rotation speed of several thousand rotations to tens of thousands rotations per minute depending on the type of raw material. Further, the time for crushing and stirring by rotating the rotary blade 3 may be 1 minute to 10 minutes or less.

After crushing and stirring the raw material M, the rotary blade 3 is stopped by stopping the drive motor 4, the combined lid 2 and the container 1 are reversed by 180 ° to return to the state shown in FIG. 3, and the container is again used. The lid 2 is detached with the opening side of 1 facing upward. Then, the raw material M to which the fermented yeast E as a livestock feed that has been crushed and agitated is added is discharged from the container 1. At this time, since the rotary blade 3 is separated from the container 1, the raw material M and the like can be easily discharged, and since the rotary blade 3 is exposed, post-treatment such as cleaning becomes easy. Workability can be further improved.

Here, an example will be described when fermented yeast E composed of Saccharomyces cerevisiae Kakegawa strain (accession number FERM P-18964) is added to the raw material M. Fermentation yeast E is added to the raw material M discharged from the container 1 in an amount of 0.1% by weight to 0.5% by weight based on the raw material M made of organic waste, and fermented by the above-mentioned pulverizing and stirring device. The yeast E is stirred so as to be evenly distributed over the whole raw material M.

Fermentation yeast E composed of Saccharomyces cerevisiae Kakegawa strain (accession number FERM P-18964) is yeast, budding yeast, and particularly yeast for producing feed. Details of the fermented yeast are described in Japanese Patent No. 3950767.

The organic waste to which the fermented yeast E is added is first left in a temperature atmosphere of 25 to 40 degrees Celsius. After that, when a predetermined time elapses, lactic acid bacteria existing in nature first adhere to organic waste and lactic acid fermentation starts. The above temperature atmosphere is set to a temperature suitable for fermentation of lactic acid bacteria and fermentation of Saccharomyces cerevisiae Kakegawa strain. In this temperature atmosphere, the Saccharomyces cerevisiae Kakegawa strain does not start fermentation because it rises slower than the lactic acid bacteria. After the start of lactic acid fermentation, lactic acid bacteria ferment the germs mixed in the organic waste as a feed for a predetermined time, so that the germs in the organic waste are gradually sterilized.

Normally, when left in an atmosphere of 25 to 40 degrees Celsius, lactic acid fermentation is carried out by lactic acid bacteria in the natural world, but the sugar content of wood chips, mushroom waste floor materials, bamboo materials, etc. is relatively low. In that case, lactic acid bacteria in the natural world are insufficient, and lactic acid fermentation may be delayed. In this case, an appropriate lactic acid bacterium may be added to surely start the lactic acid fermentation.

After that, when the above-mentioned atmosphere of the predetermined temperature is continued, the fermented yeast E composed of the Saccharomyces cerevisiae Kakegawa strain stands up and starts fermentation. At this time, the fermented yeast E propagates using lactic acid bacteria as feed to reduce lactic acid bacteria and ferment organic waste to produce fermented feed. As a result, the decomposition of organic waste is promoted, and a fermented feed that is easily digested and absorbed with a slight alcohol-like odor can be obtained. If necessary, the fermented feed may be dried until the water content is 40% or less. By drying the fermented feed in this way, the storage period can be further extended.

The fermented feed can be provided as livestock (cattle, pig, chicken, goat, horse, etc.) feed, farmed (fish, shellfish) feed, and pet animal (dog, cat, small bird, ornamental fish, etc.) feed. Fermented feed obtained by fermenting organic waste with fermenting yeast E consisting of Saccharomyces cerevisiae Kakegawa strain can be particularly used as feed for pigs. Since this fermented feed is accompanied by a slight alcohol-like odor, it has good palatability and is excellent in digestion and absorption, and can contribute to the promotion of health and growth of livestock, aquaculture and pet animals. In livestock, the accident rate of ascites and sudden death syndrome, reduction of antibiotics, promotion of growth and improvement of meat quality can be achieved, and at the same time, reduction of organic waste, recycling and reduction of livestock feed cost can be achieved. Can be planned.

When pigs were fed fermented feed as livestock and bred, unsaturated fatty acids increased in both muscle and fat parts, and in particular, linoleic acid increased by about 5% compared to the concentrated feed generally fed. It has been confirmed that. In addition, saturated fatty acids such as stearic acid tend to decrease on the contrary, and can be changed to the meat quality of a healthy component when a person eats. Moreover, when only the above-mentioned fermented feed was fed to the chickens without feeding the general mixed feed, the growth of the chickens could be accelerated. In addition, despite not administering veterinary drugs such as antibiotics, there were no accidents due to infectious diseases. Furthermore, it has been confirmed that the meat and chicken eggs do not develop an allergic reaction even when eaten by a person with allergic symptoms, and in particular, they are eaten for patients with atopic dermatitis, but there are no cases of onset.

6 to 11 show a second embodiment as an inversion means for upside down in a combined state in which the lid is attached to the open end of the container in the pulverizing and stirring device. This second embodiment is substantially the same as the first embodiment described above, except that a passive connector connected to the rotary blade is arranged on the lid and an output connector is provided on the fixed base. When the lid is mounted on the fixed base, the passive connector is engaged with the output connector to rotate the rotary blade. The same reference numerals as those in the first embodiment described above indicate the same parts, and detailed description thereof will be omitted.

First, the configuration of the second embodiment will be described with reference to FIG. The lid 20 is formed in a substantially disk shape, with an upper recess 20a formed above and a lower recess 20b formed below the partition wall 20c. The outer circumference of the upper recess 20a is formed to have an outer diameter that fits into the open end of the container 1, and the outer circumference of the lower recess 20b is formed to have an outer diameter that fits into the upper recess 21b of the fixing base 21.

A rotary blade 3 is rotatably arranged in the upper recess 20a of the lid 20. Further, a passive connector 22 that rotates integrally with the rotary blade 3 is mounted in the lower recess 20b. The rotary blade 3 and the passive connector 22 are connected by a rotary shaft 23, and the rotary shaft 23 is rotatably supported by a bearing provided in the center of the lid 20.

On the other hand, in the fixing base 21, an upper recess 21b is formed above the partition wall 21a, and a lower recess 21c is formed below. An output connector 24 is attached to the upper recess 21b, and a drive motor 4 is disposed in the lower recess 21c. The tip end side of the output shaft of the drive motor 4 is connected to the output connector 24, and the output connector 24 is integrally rotationally driven by the rotation of the drive motor 4.

Then, when the lower recess 20b side of the lid 20 is fitted into the upper recess 21b of the fixing base 21, the tooth portion of the passive connector 22 meshes with the output connector 24, and the rotation of the drive motor 4 is transmitted to the passive connector 22. The rotary blade 3 is rotationally driven.

Next, the operation of the pulverizing and stirring device and the method for producing livestock feed according to the present invention will be described with reference to the second embodiment shown in FIGS. 7 to 11. First, as in the first embodiment described above, as shown in FIG. 7, the container 1 is filled with the raw material M for livestock feed and, if necessary, with the opening side of the cup-shaped container 1 facing upward. Fermented yeast E is added. Then, as shown in FIG. 8, with the lid 20 inverted, the upper recess 20a side is fitted to the open end of the container 1 and sealed. Both may be fixed by well-known fixing means in order to maintain the sealed state. After fitting the lid 20 into the container 1 to bring it into a united state, the container 1 and the lid 20 are inverted as shown in FIG. In this state, the raw material M or the like in the container 1 descends downward, so that the rotary blade 3 is covered with the raw material M.

After that, with the container 1 and the lid 20 inverted, the lower recess 20b side of the lid 20 is fitted into the upper recess 21b of the fixing base 21, and the tooth portion of the passive connector 22 is engaged with the output connector 24. Then, by rotationally driving the drive motor 4, as shown in FIG. 10, the rotary blade 3 rotates to the output connector 24 via the passive connector 22, and as described by the first embodiment described above, the container. By flowing the raw material M and the fermented yeast E contained in 1 as shown by arrows, the mixture is evenly and uniformly stirred. Then, after crushing and stirring the raw material M, the lid 20 is separated from the open end of the container 1, and as shown in FIG. 11, the container 1 is tilted and the raw material M inside is discharged to another container or the like (not shown). To do.

In the second embodiment configured in this way, since the output connector 24 and the passive connector 22 can be separated, for example, a plurality of containers 1 and a lid 20 are prepared, and one is installed in the pulverizing and stirring device. Then, crushing and stirring are performed, and during that time, it is possible to rotate the work such that the raw material M or the like is put into or discharged from the container 1, and the work efficiency can be improved. Further, since it is not necessary to install and move the drive motor 4 having a relatively large weight on the fixed base, there is an effect that the danger during the work can be prevented.

Although the present invention has been specifically described above based on the examples, it goes without saying that the present invention is not limited to the above examples and can be variously modified without departing from the gist thereof. In the above-described embodiment, the shape and configuration of each part such as the container, the lid, and the rotary blade may be changed as appropriate.
