  Here, natto boiled beans produced from the manufacturing process of natto are already in a state where natto bacteria are already contained in the boiled natto, so it is desired to actively use this. .

  However, in the case of natto boiled beans, it is difficult to preserve because of its high water content, and it is a problem whether natto boiled beans can be transported from a natto factory to a feed factory and converted into feed.

  Then, an object of this invention is to provide the production method of a feed which can implement | achieve the feed conversion which uses natto boiled beans as the raw material of a feed.

1st invention collect | recovers natto boiled beans and produces the feed which uses this natto boiled beans as a raw material,
A recovery process for recovering the heat-treated natto boiled beans in an anaerobic state;
A feed process for feeding natto boiled beans recovered in the recovery process by lactic acid fermentation ,
The feed conversion step is performed by lactic acid fermentation of the natto boiled beans at a temperature not lower than the first temperature at which the lactic acid bacteria become active and less than a second temperature higher than the first temperature at which the natto bacteria become active. The natto boiled beans are lactic acid fermented in a state where the activity of lactic acid bacteria related to lactic acid fermentation is superior to the activity of natto bacteria contained in natto boiled beans .

  According to 1st invention, in the process of collect | recovering the heat-treated natto boiled beans, it can suppress that a natto boiled bean decays by making it an anaerobic state, This is preserve | saved until the next feed process, It can be transported.

  Furthermore, in the feed conversion step, natto-boiled beans are actively lactically fermented, whereby the natto-boiled beans can be silaged and used as a raw material for simple feed or fermented TMR feed.

Thus, according to 1st invention, the feed conversion which uses natto boiled beans as the raw material of feed can be implement | achieved.
Moreover, according to 1st invention, a smooth lactic-acid fermentation is implement | achieved by making the activity of the lactic acid bacteria which concerns on lactic acid fermentation have a dominant state with respect to the activity of the natto bacteria contained in boiled natto in a feed conversion process. It is possible to feed natto boiled beans.
Specifically, in the feed conversion process, the lactic acid bacteria are in an active state and the temperature range in which the natto bacteria do not become active, the activity of the lactic acid bacteria is dominant and the activity of natto bacteria contained in the boiled natto is suppressed It can be. Thereby, also when using natto boiled beans as a raw material of feed, smooth lactic acid fermentation is realizable.

The second invention is the first invention,
The recovery step includes
A first recovery step of packing natto boiled beans discharged in the natto manufacturing process in a sachet;
And a second recovery step in which the natto boiled beans packed in a small bag in the first recovery step are refilled into a large bag and subjected to anaerobic treatment.

  According to the second invention, the recovery step is primarily anaerobic by stuffing the natto boiled beans discharged at the natto factory or the like in the first recovery step into a sachet at each manufacturing step where the natto boiled beans are discharged. It can be.

  Furthermore, in the second recovery step, the natto boiled beans in a small bag are refilled into large bags and subjected to anaerobic treatment such as degassing, so that the natto boiled beans are secondarily anaerobic and are suitable for storage and transportation. can do.

The third invention is the first invention or the second invention,
The feed conversion step is characterized in that the natto boiled beans are subjected to lactic acid fermentation under acidic conditions so that the activity of natto bacteria contained in the natto boiled beans is suppressed.

According to the third invention, since the activity of natto bacteria decreases in an acidic atmosphere, the activity of natto bacteria contained in natto boiled beans can be suppressed by making the feed process acidic. It can be avoided that the activity of natto bacteria is dominant and lactic acid fermentation is suppressed. Thereby, also when using natto boiled beans as a raw material of feed, smooth lactic acid fermentation is realizable.

Explanatory drawing which shows the whole structure of the method of collect | recovering natto boiled beans and producing the feed which uses this as a raw material.

  As shown in FIG. 1, the method for producing a feed using natto boiled beans as a raw material of the present embodiment collects natto boiled beans discharged from natto factory 1 between natto factory 1 and feed factory 2. This is processed into feed for livestock in the feed factory 2, and the processed feed is supplied to, for example, a ranch (dairy farming association) 3 and fed to a dairy cow or the like that needs a high protein feed.

  More specifically, a method for producing a feed made from natto boiled beans includes a recovery process for collecting natto boiled beans from natto factory 1 to feed factory 2, and a feed process for converting natto boiled beans into feed in feed factory 2 Is provided.

  First, the process of recovering natto boiled beans includes a first recovery process (FIG. 1 / STEP 11, corresponding to the first recovery process of the present invention) and a second recovery process (FIG. 1 / STEP 12, second recovery process of the present invention). Corresponding to the process).

  In the first recovery process (FIG. 1 / STEP 11), in the natto manufacturing process, the discharged natto boiled bean residue is collected and packed in a sachet.

  In this process, natto boiled beans, which are determined to be mainly out of specification in the natto manufacturing process, are packed in a small bag in a short time from the occurrence, thereby making the natto boiled beans primarily anaerobic.

  And the natto boiled beans packed in the sachet are temporarily accumulated in a container near the production line (near the place where it occurs), and the container has a second collection process (for example, every 3 hours). 1 / STEP 12) It is moved to the pickup location.

  In this way, the natto boiled beans packed in a small bag transferred in container units are opened in a large bag (for example, a flexible container bag with an inner bag) at the collection location, and the large bag is deaerated using a suction device. As a result, the natto boiled beans are secondarily anaerobic. Thereby, it can be made into the state suitable for long-term storage, conveyance, etc. (unlike the case of bagging with a small bag).

  Furthermore, when degassing a large bag with a suction device, unnecessary moisture can also be sucked from the bag, so when transporting large natto boiled beans on a truck etc., the weight should be reduced. Can do.

  Next, the natto boiled beans transported from the natto factory 1 to the feed factory 2 in the form of large bags are silaged in the feed factory 2 (FIG. 1 / STEP 21, corresponding to the feed process of the present invention).

  Specifically, in silageization, by making anaerobic conditions, activities of bacteria and the like that prefer oxygen are suppressed, and instead, activities of lactic acid bacteria become active. Lactic acid is produced by this lactic acid bacteria activity (lactic acid fermentation), and PH decreases. This decrease in PH further increases the activity of lactic acid bacteria. When PH decreases to about 4.2, lactic acid fermentation becomes stable and silageation is completed.

  In this embodiment, addition of lactic acid bacteria, addition of sugar, and adjustment of moisture are not performed in the silageization process.

  In this treatment step, it is particularly preferable that the activity of lactic acid bacteria that plays an important role in silage formation is superior to the activity of natto bacteria contained in boiled natto beans. Therefore, you may actively suppress the activity of Bacillus natto.

  For example, lactic acid fermentation of natto boiled beans at a first temperature (eg, 10 ° C.) or higher at which lactic acid bacteria become active and less than a second temperature (eg, 50 ° C.) that is higher than the first temperature at which natto bacteria become active. Can be made. In particular, in summer, when the outside air temperature is around 30 ° C., smooth lactic acid fermentation can be realized by performing temperature management during silage formation.

  Moreover, simply, natto boiled beans may be lactic acid fermented under acidity to suppress the activity of natto bacteria and realize smooth lactic acid fermentation. In general, the lactic acid fermentation progresses to lower the PH, and as a result, the activity of Bacillus natto can be suppressed.

  In this embodiment, silage was performed with the temperature being equal to or higher than the first temperature and lower than the second temperature. As a result, the feed obtained had a pH of 4.1, and the V score, which is the evaluation value of fermentation quality, was a high evaluation value of 98.7.

  Furthermore, the silaged feed was supplied to the ranch 3 as a simple feed and a fermented TMR raw material and fed to dairy cows. As a result, it was also confirmed that the palatability, milk yield, and milk components of dairy cows were not different from those of heat-pressed pen soybeans.

  As described above in detail, according to the feed production method of the present embodiment, it is possible to realize a feed using boiled natto beans as a feed material.
