Description

  The present invention relates to a drying processing apparatus, a stirring body, and a drying processing method. More specifically, for example, the present invention relates to a drying apparatus, a stirrer, and a drying method that can sterilize chickens that have died during breeding in a poultry farm by high-temperature treatment and sterilize them in a short time.

  For example, in a poultry farm that produces broilers, about 2 to 4% of chickens die due to illness during the 60-day breeding period. These moribund chickens need to be disposed of early so that they do not become a source of foul disease or a source of malodor. In other words, on a poultry farm that raises 100,000 broilers, it is necessary to dispose of 30 to 40 birds on average every day.

  There are various methods for disposing of moribund chickens: (1) buried in soil, (2) treatment with fermenter, (3) incineration, etc. (1) is not a preferable treatment method because it requires a large amount of land to dispose of it and may be a source of groundwater contamination. Moreover, as what performs disposal of (2), there exists a processing apparatus of patent document 1, for example, and there exists an incinerator of patent document 2 as what performs disposal of (3), for example.

  In the processing apparatus described in Patent Document 1, an endless transport path is formed, a processing layer in which a moribund chicken is input and stored together with chicken dung, a moribund chicken is cut and subdivided, and the subdivided moribund chicken and Air can be supplied by stirring the mixture with chicken manure, and has a stirrer having a moving wheel in which tilling nails are radially planted around the rotating shaft, facing from above the treatment layer, The early processing can be achieved reliably and easily.

  Moreover, the incinerator described in Patent Document 2 includes a combustion device and a supply device that feeds a combusted material to the combustion device, the supply device includes a conveyor, a collapsing device, and the combustion device has a combustion chamber. A carbonization device that heats and carbonizes in an oxygen-free state while conveying a combusted material that is provided in the combustion chamber and sent by a supply device to the discharge side, and a combustible gas and a carbide that are provided in the combustion chamber and discharged from the carbonization device. Equipped with a combustion section that burns in an aerobic state while transporting it to the discharge side, and a discharge conveyor that discharges burnt ash to the outside. It can be done.

However, the processing apparatus described in Patent Document 1 and the incineration apparatus described in Patent Document 2 have the following problems.
First, the processing apparatus described in Patent Document 1 ferments and processes moribund chickens in a processing tank while stirring them, and requires a large area for installing the processing tank. Moreover, it takes considerable time to process the moribund chicken by the processing apparatus. For this reason, there is a big problem that wild beasts such as stray dogs or sanitary pests causing in-field contamination and invasion of wild birds causing infrequent occurrence of bird flu in recent years are likely to occur.

  Therefore, it is possible to perform the processing by an incinerator that can perform the processing in a short time and hardly causes a stray dog, a wild bird or the like to enter the field. The incinerator described in Patent Document 2 has been proposed by the present inventor and is sufficiently useful for incineration of chicken manure and the like. However, if this is used for the treatment of moribund chickens, the following problems arise.

  In other words, since moribund chickens are disposed of as so-called whole chickens, if moribund chickens placed in the processing chamber are stirred with ordinary stirring blades, they are considerably long until they become fine even though they are treated at high temperatures. Need time. Moreover, even if meat, feathers, etc. are finely pulverized, thick bones such as foot bones are not pulverized and remain as large bone fragments. In addition, since the fat percentage of the whole chicken is about 25%, there is a fundamental problem that the inside of the processing chamber becomes slippery with oil, and even if it is stirred inside, it turns around in one lump and the stirring efficiency is extremely poor.

(Object of the present invention)
The object of the present invention is, for example, when disposing of a moribund chicken that has died in the middle of breeding in a poultry farm, by cutting the moribund chicken in the processing chamber and making it finer, there is a lot of oil contained in the moribund chicken and the processing chamber slips. Even if it becomes easy, it is possible to perform reliable and efficient agitation, and to sterilize the processed material by high-temperature processing and to perform almost complete pulverization processing without bone fragments in the processed material in a short time It is to provide a drying apparatus, a stirring body, and a drying method.

(Function)
The operation of the drying apparatus according to the present invention will be described. Here, the constituent elements used in the description are assigned in correspondence with the reference numerals given to the respective parts in the embodiments described later. These reference numerals are the same as the reference numerals described in the claims of the claims. Similarly, it is only for the purpose of facilitating understanding of the contents, and the meaning of each component is not limited to the above-described parts.

A case where the workpiece is a moribund chicken will be described as an example. First, the processing chamber is heated by the heating chamber and the stirring body is rotated by the drive system. And the moribund chicken which is a to-be-processed object is thrown into a processing chamber from an input part with a circle.
Each moribund chicken that has been thrown in is cut by the bones in turn by the detents provided in the required number on the rotating shaft of the stirring body. This cutting is mainly performed at the bottom of the processing chamber due to the weight of the object to be processed, and returns to the inner surface when a part or the outer periphery of the detent portion rotates and moves close to the inner surface of the bottom of the processing chamber. The process is performed so that the workpiece is sandwiched between the stoppers.

  In parallel with the cutting of the object to be processed by the detent part, the cut object to be processed is fed in one direction in the axial direction of the rotating shaft while being stirred by the feed stirring part. In addition, the moribund chicken that is the object to be processed has a high fat percentage and it is easy to slip with oil in the processing chamber, but the object to be processed is finely cut by cutting to the bone, and it is difficult to make a lump when stirring, Stir efficiently.

  The workpiece to be sent is pushed by the workpiece to be sent subsequently, the pressure is increased at one end of the processing chamber, and the feed agitating unit located near one end is kept at a high temperature and high pressure for a certain period of time. Kneaded. At this time, the object to be processed tries to return to the direction in which the pressure is released, that is, the direction opposite to the feeding direction, but most of the object is stopped by each of the detents that are rotating and moving. The high pressure of the object is maintained.

  When such high temperature and high pressure processing is performed for a predetermined time, the rotation direction of the agitator is switched by the control unit, and the agitator rotates in the opposite direction. As a result, the object to be processed is sent in the opposite direction to the above in the processing chamber, and the processing at a high temperature and high pressure is performed for a predetermined time at the end in the processing chamber in the same manner as described above. During the treatment, the side where there is no workpiece in the treatment chamber has a higher temperature, and even when the workpiece moves, an efficient treatment can be performed at a sufficiently high temperature. it can.

  The rotation direction of the stirrer is controlled so as to be switched at regular time intervals. By repeating the above process, the object to be processed is dried and gradually powdered. Then, when the processing time exceeds a certain time, finally, the remaining bone fragments are pulverized all at once, although the reason is not clear. The pulverized processed product is sufficiently sterilized by high temperature and high pressure during processing. The processed product is discharged from the discharge section of the processing chamber and used for feed or the like as necessary.

  For example, in the case of disposing of a moribund chicken, the drying treatment apparatus according to the present invention cuts the moribund chicken in a processing chamber to make it finer, so that even if there is a lot of oil contained in the moribund chicken and the processing chamber becomes slippery In addition, in the processing chamber, the processing can be performed under high temperature and high pressure by the action of the feed stirring section and the detent section, so that the processed product can be sterilized. Almost complete pulverization processing in which bone fragments are not included in the processed material can be performed in a short time.

(Function)
With reference to FIG. 1 thru | or FIG. 6, the case where a to-be-processed object is a moribund chicken is demonstrated as an example about the effect | action of the drying processing apparatus A which concerns on this Embodiment.
First, the burner 41 below the heating chamber 4 is ignited to heat the processing chamber 1, and the agitator 2 is rotated by the driving device 3. Then, the lid plate of the lid device 49 is opened, and the moribund chicken, which is the object to be processed, is thrown into the processing chamber 1 from the feeding unit 48 as a circle. The lid plate of the lid device 49 is closed.

  Each of the moribund chickens that have been thrown in is cut into small pieces and finely cut in sequence with the bones by the detent plates 25 provided in the required number on the rotating shaft 21 of the stirrer 2. This cutting is performed mainly at the bottom of the processing chamber 1 due to the weight of the workpiece, and the blade portion 28 provided on the outer peripheral portion of the detent plate 25 is close to the inner surface of the peripheral wall 10 of the processing chamber 1. When rotating, the workpiece is sandwiched between the inner surface of the peripheral wall 10 and the blade portion 28.

  In parallel with the cutting of the workpiece by the detent plate 25, the cut workpiece is fed in one axial direction of the rotary shaft 21 in the processing chamber 1 while being stirred by the housing 23 and the blade plate 24. It is done. In addition, as described above, the moribund chicken that is the object to be processed has a high fat percentage, and the inside of the processing chamber 1 becomes slippery with oil. However, the object to be processed is finely cut by cutting up to the bone. It is hard to become a lump and is efficiently stirred. The sent object to be processed stops at the end wall 11 or the end wall 12 of the processing chamber 1, and is pushed by the object to be processed that is subsequently sent to increase the pressure at the end.

  Further, they are kneaded while being rubbed strongly for a predetermined time under high temperature and high pressure by the casing 23 and the blade plate 24 of the stirring paddles 22 and 22a located in the vicinity of the ends. At this time, the object to be processed tends to return in the direction in which the pressure is released, that is, in the direction opposite to the feeding direction. However, since most of the detent plate 25 is rotated and moved, the high pressure of the workpiece is maintained. It should be noted that a part of the object to be processed whose pressure has been increased can be returned through the pressure release hole 27 of each detent plate 25 to prevent an excessive increase in the pressure of the object to be processed. Yes.

  When such processing at high temperature and high pressure is performed for a predetermined time, the rotation direction of the stirring member 2 is switched by the control unit, and the stirring member 2 rotates in the opposite direction. As a result, the object to be processed is sent in the opposite direction to the above in the processing chamber 1, and processing at a high temperature and high pressure is performed for a predetermined time at the end in the processing chamber 1 as described above. During the processing, the side of the processing chamber 1 where there is no object to be processed has a higher temperature, and even when the object to be processed moves, an efficient processing is performed at a sufficiently high temperature. Can do.

The rotation direction of the agitator 2 is controlled so as to be switched at regular time intervals. By repeating the above process, the object to be processed is heated and dried, and gradually powders. When the processing time exceeds a certain time, finally, the remaining bone fragments are pulverized all at once, although the reason is not clear. Needless to say, the pulverized processed product is sufficiently sterilized (sterilized) by high temperature and high pressure during processing.
The processed material in the processing chamber 1 is discharged to the outside through the chute 18 by opening the cover plate of the cover device 16, and is used as feed or the like as necessary.

  Note that the terms and expressions used in the present specification are merely explanatory and not restrictive, and do not exclude terms and expressions equivalent to the above terms and expressions. The present invention is not limited to the illustrated embodiment, and various modifications can be made within the scope of the technical idea.
