Description

  The present invention relates to a technique for effectively utilizing a non-standard product produced in the production process of tofu or fried chicken as a feed.

  A technique for reusing okara that is produced in large quantities in the production process of tofu and fried tofu is disclosed. For example, Patent Document 1 discloses a technique for producing a regenerated food material by mixing a food residue having a high water content with dried okara and then further drying it.

JP2008-212131

  However, for non-standard products that are produced in large quantities every day in the manufacturing process of tofu and fried tofu, there is no technology for how to reuse them, and they are simply treated as waste or dehydrated into compost. Either. A non-standard product is a product that loses its product value as a defective product due to its shape being lost in the manufacturing process, for example, when the tofu is packed in packs, the corners of the product are missing, or the fried chicken is warped or folded. Refers to things. And the amount reaches 600t / month. In addition, tofu and fried tofu are soy products, which are rich in protein and high in nutritional value. Therefore, development of technology that can effectively use these non-standard products is required.

  On the other hand, livestock feeds that are in the process of growing chicken chicks and piglets with high productivity are required to have high protein, high calories, and high nutritional value, but feeds rich in nutrients are common. There is a problem that it is expensive.

  Therefore, in the present invention, it is proposed to provide a highly nutritious livestock feed and a method for producing the livestock feed using non-standard products generated in the production process of tofu and fried tofu.

In order to achieve the above object, the present invention solves the following problems.
(1) Provided is a livestock feed characterized by containing dried powder obtained by vacuum drying non-standard tofu and non-standard fried tofu produced in the process of producing tofu and deep-fried tofu.
(2) Moreover, 80-90 weight part of feed and 10-20 weight part of said dry powder are mixed, The feed for livestock as described in (1) characterized by the above-mentioned is provided.
(3) In addition, (1) or (2), wherein the pre-dry weight of the non-standard fried tofu and the pre-dry weight of the non-standard tofu are in the range of 1: 9 to 2: 8 The feed for livestock described is provided.
(4) Furthermore, after crushing the crushed non-standard fried oil and the non-standard tofu tofu in a vacuum ratio of 1: 9 to 2: 8 to obtain a dry powder, 80 to 90 parts by weight of the feed and the dry powder Provided is a method for producing livestock feed characterized by mixing 10 to 20 parts by weight.

  According to the livestock feed and the method for producing livestock feed according to the present invention, it is possible to effectively utilize tofu and non-standard fried products that have only been treated as waste.

  Moreover, the nutritional value of feed can be increased by adding to existing inexpensive feed.

It is explanatory drawing which shows the manufacturing method of the livestock feed which concerns on this invention.

  Hereinafter, the present invention will be described in detail with reference to the drawings. First, as shown in FIG. 1, the non-standard oil frying generated in the manufacturing process is crushed into a paste by a crushing machine such as a grinder or a chopper (step S102). In addition, non-standard-sized fried oil is crushed into a paste form, and then comes into a powder form by subsequent drying. Moreover, since fried oil uses oil, it has a higher calorie than tofu and can provide a livestock feed that is higher in calories than when only non-standard tofu is dried and mixed with the feed. In addition, when it comes to frying, it can be used regardless of the type.

  Next, paste-like non-standard fried oil is put into a vacuum dryer together with non-standard non-form tofu and dried while mixing (step S104). An existing vacuum dryer can be used, and it is preferable to use a vacuum dryer capable of stirring the object together with vacuum drying under reduced pressure. In addition, since tofu is fragile and easily broken, the shape is broken by stirring and drying in a vacuum dryer, and the powder looks like a powder even if it is not pulverized beforehand like fried. The drying method may not be vacuum drying, but it is preferable to use vacuum drying in consideration of the cost for drying. Regarding tofu, cotton tofu and silken tofu can be used, and any kind of tofu can be used as long as it belongs to tofu.

  Here, with respect to the weight before drying, it is preferable to mix and dry so that the ratio of non-standard fried tofu and non-standard tofu is about 1: 9 to 2: 8. The moisture content of fried tofu is 45 to 55%, whereas the moisture content of tofu is 80 to 90%, and tofu has a higher water content than fried tofu. Therefore, the weight ratio of the fried tofu and the dried powder of tofu is approximately 1: 3 to 1: 4.

  In addition, tofu is high protein, while fried chicken is high in calories, and when blended in the above proportion, a balanced livestock feed can be provided. That is, when only fried fried food is mixed with feed, protein is insufficient, and when only tofu is mixed with feed, calories are insufficient.

  The vacuum drying conditions can be described. For example, it can be vacuum-dried for about 12 hours while stirring at a pressure of 55 to 65 ° C. in an atmosphere of 0.7 atm. In addition, about the mixture of non-standard tofu and non-standard fried oil fried, it can be dried under any conditions as long as the moisture content before drying is from 85 to 90% and the moisture content after drying is 10% or less. is there.

  The dry powder that is a mixture of fried tofu and tofu obtained as described above has the components shown in the table below.

  As can be seen from Table 1, the dry powder obtained by the present invention is characterized in that it contains about twice as much protein as a normal feed. Moreover, magnesium is not contained only by making soybeans into a dry powder, but since dried bittern is used in the manufacturing process for tofu and fried chicken, the dry powder according to the present invention contains magnesium as a component. Yes. Magnesium is a nutrient that is indispensable for forming bone together with calcium, and is preferably contained in a large amount in feeds such as chicken chicks and piglets. In addition, because it is derived from tofu and fried chicken, it contains mineral components such as phosphorus, and these are feeds for livestock that have high nutritional value by blending the dry powder obtained in the present invention with conventional feed It can be obtained.

  Next, the dry powder obtained by the above process is mixed with conventional feed (step S106). This feed may be commercially available from rice, rice bran, corn or the like as a raw material. And since these feeds with low nutritional value are generally inexpensive, the nutritional value of these inexpensive materials as a whole can be increased by adding the dry powder according to the present invention. Since the dry powder according to the present invention is a waste in the first place, a livestock feed having the same nutritional value as an expensive feed can be provided at low cost. Here, the blending ratio of the conventional feed and the dry powder will be described. Since the dry powder is a high protein and high lipid, the feed can be mixed at a ratio of 80 to 90 parts by weight and the dry powder at a ratio of 10 to 20 parts by weight. preferable. In addition, it is possible to increase the amount of protein in the feed by 3% or more by adding 10% of the dry powder to the feed. This makes it possible to provide a low-cost livestock feed while having the same nutritional value as an expensive high-nutrition feed.

After crushing 850 kg of non-standard fried oil into a paste, 7650 kg of non-standard tofu, 8.5 tons as a whole, is put into a vacuum dryer. The moisture content before drying of non-standard fried tofu and non-standard tofu is 85 to 90%. These mixtures are evacuated in an atmosphere having a degree of vacuum of 0.7 Mp and a drying temperature of 60 ° C., and steam heating is performed at a steam pressure of 0.25 Mp for 12 hours. Thereby, it can dry faster than the drying in an atmospheric condition. The moisture content after drying is preferably 10% or less. Of course, drying under other conditions is also possible. Thereafter, for example, the dry powder obtained thereby is mixed with 1 to 2 kg at a rate of 8 to 9 kg to obtain a feed with high nutritional value.
