Description

  The present invention relates to a method for producing a wet feed containing high moisture.

  A wet feed containing moisture is known from Patent Document 1, for example. As a conventional method for producing a wet feed, water is added to hay, and the hay is sufficiently absorbed and then packed in a sealed container for lactic acid fermentation. A transformer bag is used as the sealed container. In order to obtain a sealing property, a bag made of a plastic film such as polyvinyl or nylon (registered trademark) is used in the container. The feed material is placed in a hopper and sealed.

JP-A-4-258259

  In the above conventional wet feed manufacturing method, feed material is charged and sealed in a bag-like container having airtightness, so that it is easy to handle after sealing. There is an advantage that it can be moved and transportability and storage are good.

However, since the sealed container is a tearable plastic film, the packing density to this cannot be so high as 150 kg / m ³ , so that a large amount of air remains in the feed after filling, thereby causing mold. The fermentation quality was difficult to stabilize. And in order to solve this problem, before closing a sealed container, the air in this must be sucked with a vacuum pump, and the new problem that the process for this will increase will arise.

  The present invention has been made in view of the above, and provides a method for producing a wet feed that can seal and wrap the material of the wet feed with a large density and can obtain a wet feed of extremely excellent quality. It is the purpose.

  In the method for producing a wet feed for achieving the above object, a high moisture feed material is compression-molded, a strip-like film having stretch properties is wound around the entire circumference, and stored for a predetermined number of days.

  According to the present invention, the feed material can be packed with a large density by compaction molding and the stretching force of the stretch film, and the intrusion of air into the feed material at the time of storage ripening can be reduced and mold does not occur. Moreover, each of lactic acid, acetic acid, and total acid is produced in a large amount, and an excellent wet feed can be obtained. Also in this manufacturing process, the process of compressing the feed material and the process of winding the band-shaped film around the compression molded body can be performed in a series of continuous work processes, making the manufacturing process a line. can do. Furthermore, the strength as a package can be increased as compared with the conventional one using a single plastic bag by using a belt-like film having stretchability as the packaging material.

  As shown in FIG. 1, a feed material A that has been press-molded into a predetermined shape, for example, a cube, is wound with a band film 2 partially overlapped from the periphery of the feed material A, and further wound in multiple layers. A wet feed C is produced by winding the entire circumference with a belt-like film B. A stretch film is used as the belt-like film B, and the cubic feed material is kept in a pressurized state by the stretch force of the belt-like film by winding it while stretching it. Then, it is stored for a predetermined number of days, for example, 13 to 40 days to obtain a wet feed. As the feed material A, a material obtained by mixing hay or concentrated feed with food by-products such as high-moisture beer cake and tofu cake is used.

The chucking portion 18 has chucking blades 18a and 18b that rotate in directions opposite to each other, and opens to the left and right while the strip film B is wound so as not to interfere with the strip film B. At the time of cutting, this protrudes toward the belt-like film B, and the chucking blades 18a and 18b are rotated inwardly and chucked by both chucking blades 18a and 18b as shown in FIGS. It has become. The cutting guide bar 19 protrudes as shown in FIGS. 8, 9, and 10 at the time of cutting to receive the strip-shaped film B so that it can be easily cut.

  As shown in FIGS. 2 and 3, a transport rotary table device 21 provided at a predetermined interval 20 in the transport direction is disposed on the downstream side of the conveyor mechanism 6 of the ring packaging device 1. The conveyance rotary table device 21 includes a conveyance table 22 and a rotation device 23 that rotates the conveyance table 22 in the horizontal direction about a vertical axis.

  The transport table 22 has a large number of long plate members 24 endless in the transport direction, connected by a chain and wound around a drive roller 25 and a driven roller 26, and a transport band 27 standing at a transport direction end portion. The stopper 28 is provided. Each plate member 24 of the transport band 27 is provided with a large number of roller rollers 29 with the rotation axis inclined by 45 ° with respect to the transport direction, and the feed material A transported in the transport band 27 is stopped by the stopper 28. In this state, the repulsive force at this time is transmitted to the roller 29, and the force for moving the feed material A in the right-angle direction acts. A large number of rollers are provided on the surface of the stopper 28, and the feed material A that is in contact with the stopper 28 is moved in the right-angle direction without receiving resistance from the feed material A in contact with the stopper 28. A conventionally well-known thing (brand name: Seitaro, Toho Machine Industry Co., Ltd.) is used for the part of the conveyance table 22 of this structure. Reference numeral 30 denotes a drive motor that drives the transport belt 27.

  The conveying table 22 is placed on a rotating device 23 and can be rotated by 90 ° with respect to the traveling direction of the conveyor mechanism 6 of the ring packaging device 1.

  A pressure forming device 31 for press-forming the feed material A as shown in FIG. 12 is arranged on the upstream side of the transport conveyor 8 of the belt-shaped film winding device having the above configuration. The pressure molding device 31 is a hopper 32 for feeding the feed material A and a pressure plate 34 reciprocatingly moved by the cylinder device 35 toward the molding frame 33 provided on the lower side of the hopper 32. And a pressure device 36. An opening / closing plate 37 for opening and closing the opening end is provided at the opening end of the molding frame 33 so as to be opened and closed by an opening / closing device (not shown).

  The manufacturing method of the wet feed C using the apparatus of the said structure is demonstrated below.

  In FIG. 12, the feed material A is introduced from the hopper 32 of the pressure molding device 31 with the open / close plate 37 closed, and the pressure plate 34 is reciprocated by the expansion and contraction of the cylinder device 35 to add the feed material A. Press.

  As the feed material A, food by-products such as beer lees, Sudan hay, cacao shells, and tofu lees are used. In this example, beer lees, Sudan hay and cacao shells were used.

  In the pressure molding apparatus 31, the feed material A input from the hopper 32 is compressed to a predetermined density in the molding frame 33 and formed into a shape along the molding frame 33, for example, a cubic shape. Thereafter, the opening / closing plate 34 is opened and pushed out onto the conveyor 8 by the pressure plate 34.

  The feed material A on the transport conveyor 8 is carried by the transport conveyor 8 onto the conveyor mechanism 6 of the ring packaging apparatus 1 of the film winding apparatus shown in FIGS. The feed material A is conveyed downstream by the conveyor mechanism 6. At this time, the cutting device 10 is moved to a position where it does not interfere with the circulating belt-like film B. In this state, the ring wrapping apparatus 1 is operated, and the belt-like film B is wound around the feed material A together with the conveyor mechanism 6. The belt-like film B is wound in a spiral shape while being stretched according to the movement of the feed material A. The belt-like film B wound around the lower part of the conveyor mechanism 6 moves downstream at the same speed as the feed material A according to the movement of the film belts 6b, 6b. And the strip | belt-shaped film B wound by the lower part of this conveyor mechanism 6 is also removed from the conveyor mechanism 6, when the feed material A remove | deviates to the downstream side of the conveyor mechanism 6 in the position of the space | interval 20. The feed material A is tightly wound by the restoring force of the belt-like film B thus formed. In accordance with the movement of the feed material A, the cutting device 10 is operated in a state in which the belt-like film B is wound over the entire length in the moving direction, and the belt-like film B is cut. At this time, the leading end of the belt-like film B is chucked by the chuck member 18 (see FIGS. 8 to 11).

  The feed material A conveyed from the conveyor mechanism 6 moves onto the conveying table 22 of the conveying rotary table device 21 and is conveyed until it abuts against the stopper 28 at the conveying band 27 of the conveying table 22.

  At this time, before the feed material A comes into contact with the stopper 28, the transport table 22 is rotated 90 ° by the rotating device 23. The rotating direction by the rotating device 23 is rotated in the direction in which the moving direction by the roller roller 29 is directed toward the conveyor mechanism 6 of the ring packaging device 1.

  If the conveying action by the conveying band 27 of the conveying table 22 is continued in this state, the feed material A is moved by the repulsive force of the roller roller 29 and is moved backward to the ring packaging device 1 side. At this time, the conveyor mechanism 6 of the ring packaging apparatus 1 is reversed. As a result, the feed material A fed back on the transfer table 22 is run backward on the conveyor mechanism 6 while being rotated 90 ° in the horizontal direction with respect to the forward running described above, and during this time the ring packaging device 1 is moved. The belt film B is wound around the feed material A in a spiral shape. Therefore, as shown in FIG. 1, the strip-shaped film B is wound on the upper and lower surfaces of the feed material A so as to intersect with each other on both the upper and lower surfaces.

  The belt-like film B is cut in a state where the winding of the belt-like film B by the reverse running is completed, and the feed mechanism A is fed downstream by causing the conveyor mechanism 6 to run forward. During this time, the transport table 22 is returned to the original posture, and the feed material A from the conveyor mechanism 6 is received and transported until it comes into contact with the stopper 28. Further, the feed material A is discharged to the side by continuing the conveyance in the conveyance band 27.

  By repeatedly performing the above-described action, the feed film A carried on the conveyor mechanism 6 is wound twice in a state in which the belt-like film B is orthogonally placed on the upper and lower surfaces of each feed material A. The belt-like film B is wound on all of the surface. The winding of the belt-like film B is not limited to double, and may be any number.

  Next, test results comparing the above-described manufacturing method according to the present invention and the conventional manufacturing method shown in the background art will be shown below. In the following, the method of the present invention is referred to as a “wrapping method” and the conventional method is referred to as a “backing method”.

(1) Test method (a) Feed material: beer lees, Sudan hay, cocoa shells (b) Component values of feed material: moisture 59.2%, ADF 30.7%, NDF 60.8% (in dry matter)
(C) Comparison method Back method: Sealed storage in polyethylene inner bag
Stuffing amount: 350 kg, apparent specific gravity: about 0.4
Lapping method: Compression molding with a pressure molding machine, and winding and storing the belt-like film all around
Packing amount: 750 kg, apparent specific gravity: about 0.55

(2) Test results (a) Comparison of fermentation quality

(3) Discussion The wrap method showed the following differences in lactic acid fermentation of wet feed compared to the back method.
(B) The wrap method has a higher pressure density than the back method, so that the amount of residual oxygen during stuffing is small, and the inflow of oxygen from the outside air is small, so that lactic acid fermentation is promoted. In the above test, there was a difference in the organic acid content. Since the organic acid content after consolidation is greater than that in the bag system, it is judged that the effect of suppressing the generation of mold is enhanced.
(B) In the back system, carbon dioxide gas is generated in the bag when it is stuffed, but there is a tendency to become negative pressure after it is released (in the polyethylene inner bag, the permeability of oxygen and carbon dioxide gas is different, so negative pressure It is estimated that this facilitates the inflow of oxygen from the outside air and promotes the generation of mold. In the lap system, such a negative pressure is not caused, and therefore it is determined that the inflow of oxygen is small. In the above test, the lap method did not cause mold.
(C) From the above, the wrapping method does not store carbon dioxide in the inner bag during storage unlike the bag method, so that the product can be easily stored and transported.
(D) Also, in the quality comparison, as the number of storage days increases in the wrap method, the amount of lactic acid, acetic acid and total acid in the feed increases compared to the back method, and the quality of the feed I found it good.
