Description

  TECHNICAL FIELD The present invention relates to a method for producing a granulated product of barley young leaf juice dry powder.

  The granules of young barley powder include granules of dried and ground powder of young barley leaves and granules of squeezed dry powder of young barley leaves. Wheat young leaf dry crushed powder is obtained by washing young wheat leaves, heating and drying, and pulverizing fine powder. Wheat young leaf squeezed dry powder is used to wash young wheat leaves, squeeze, concentrate and spray dry. Through the process of. These powders are characterized by having relatively low water absorption in dried and pulverized barley young leaves powder and very high water absorption in squeezed young barley leaf squeezed powder, depending on the manufacturing process. Since it is difficult to uniformly granulate any of the powders as they are, it is common to granulate with a binder.

  In Patent Document 1, a hygroscopic powder such as a vegetable extract powder is mixed with a dextrin as a binder, and the hygroscopic powder can be easily fluidized-bed granulated while suppressing the influence of moisture. Granulation methods are described.

  Patent Document 2 describes that the granulating property of the food material powder is improved by mixing galactomannan as a binder with the food material powder.

  In the case of granulating the dry pulverized powder of barley young leaves, the water absorption of the dry pulverized powder is not so high. Therefore, when a binder such as dextrin is mixed, a uniform granulated product can be easily produced. However, in the case of granulating the dried powder of young wheat leaves squeezed by spray-drying the juice of young wheat leaves, the water absorption of the dried powder of squeezed wheat is very high, and a binder such as dextrin is mixed to form a fluidized bed. Even if granulation is performed, the squeezed dry powder rapidly absorbs water, so that coarse particles are easily formed, and there is a problem in that a fluidity problem such as blocking is likely to occur.

  The present invention has been made in view of the above problems and has high operability in fluidized bed granulation of barley young leaf squeezed dry powder, and production of a barley young leaf squeezed dry powder capable of shortening work efficiency. It is an object to provide a method for producing granules.

That is, the present invention includes the following inventions.
[Invention 1]

[Invention 5]
Calcium is blended in an amount of 1% by weight to 3% by weight, and the method for producing a granulated product of dried powder of young wheat leaf juice according to the invention 3 or 4.

  The method for producing granules of barley young squeezed dry powder of the present invention is a high-water-absorbed barley young squeezed dried powder, since a fluidity improver is previously mixed to perform fluidized bed granulation. However, since a uniform granulated product can be easily produced, the working efficiency of the granulation process can be improved.

  Furthermore, the method for producing a granulated product of dried young wheat leaf squeezed powder of the present invention, in which the fluidity-improving agent is preliminarily compounded to perform fluidized bed granulation, the produced granulated product has a powdering state. Since it disappears, the adhesiveness of the packaging material due to the powder is eliminated, the adhesion of the granulated material to the granulation device is reduced, and the work efficiency after the granulation step is improved.

  In order to solve the above problems, the inventors of the present invention have conducted extensive studies and, as a result, when producing a granulated product of barley young leaf squeezed dry powder, include a fluidity improver in advance to form a fluidized bed. It was found that a uniform granulated product can be easily obtained by performing graining, even if the dried powder of young wheat leaf juice has high water absorbency, and completed the present invention. The method for producing a granulated product of young barley leaf squeezed dry powder according to the present invention will be described in detail below. However, the present invention is not intended to be limited to the configurations described below.

  The young barley leaf squeezed dry powder is generally produced by concentrating the young barley leaf squeezed liquid to a predetermined solid content concentration by low-temperature concentration and spray-drying or freeze-drying the concentrated liquid. This is to produce a squeezed dry powder while maintaining the flavor and nutritive value of fresh raw barley leaves. Examples of the young barley leaves used in the present invention include barley, wheat, rye and oats.

  Various methods such as extrusion granulation, stirring granulation, and fluidized bed granulation are known as methods for granulating food powder, but fluidized bed granulation is used in the present invention. Fluidized bed granulation is a method in which a raw material powder is wound into the air to form a layer in a state in which the powder flows, and a liquid is sprayed onto the layer to agglomerate or coat the powder for granulation. Fluidized bed granulation can granulate a plurality of raw materials uniformly as a granulated product.

  In the fluidized bed granulation of the present invention, the dry powdered young wheat leaf juice and the fluidity improver are put into a fluidized bed granulator, and these components are fluidized and mixed in a granulator by an air flow. When an additive such as a binder or an auxiliary agent is used, these powders are charged and then fluidized. A granulating liquid is sprayed on this mixed powder to granulate. The temperature at the time of granulation, the air flow rate, the spraying speed, the type of the granulating liquid, etc. are appropriately set.

  Due to the nature of various raw materials used, raw materials with poor fluidity are often used for foods and other granules.Therefore, granules are classified during the manufacturing process, and packing, storage, and transportation of packing materials are performed. Poor fluidity may be a problem during consumption. The fluidity improver is added to the granules in order to improve the fluidity of these granules.

  It was examined whether blocking caused by water absorbency and binding property can be prevented by adding a fluidity improver before granulation of the dried young wheat powder squeezed powder. If the fluidity improver is generally added before performing fluidized bed granulation, it becomes difficult to form a granulated product, and there is a risk of pulverization. However, surprisingly, it has become possible not only to prevent blocking but also to easily manufacture a granulated product having a uniform product form.

  Examples of the fluidity improver used in the present invention include calcium, dolomite, and finely divided silicon dioxide. Among them, calcium is preferable, and among these, seaweed calcium, sea urchin shell calcium, egg shell calcium, shell calcium, coral calcium, bone. Calcium, calcined calcium such as calcium whey phosphate is preferred.

  The content of the fluidity improver is 1% by weight to 30% by weight, preferably 1% by weight to 3% by weight, based on the total amount of the granulated product.

  In the method for producing a granulated product of the present invention, a binder may be added before granulation. Examples of the binder include dextrin, pullulan, starch, hydroxypropylcellulose, hydroxypropylmethylcellulose, methylcellulose, carboxymethylcellulose, galactomannan and the like.

[Comparison evaluation of granulation properties by different wheat barley powder]
In examining the fluidized bed granulation of the barley young leaf squeezed dry powder, first, the barley young leaf squeezed dry powder (hereinafter referred to as “SD powder”) and the dextrin-containing barley young leaf squeezed dry powder (hereinafter referred to as “compound SD powder”) Comparative test of granulation properties for sample powders of dried barley barley dry powder (hereinafter referred to as "ground powder") and dry ground barley leaf dry ground powder (hereinafter referred to as "compounded ground powder"). went.

  The SD powder used was obtained by washing young barley leaves, squeezing, concentrating, and spray drying (manufactured by Nippon Pharmaceutical Co., Ltd.). As the compounded SD powder, a compounded product of this SD powder and an appropriate amount of dextrin (trade name: Paindex, Matsutani Chemical Industry Co., Ltd.) was used. As the pulverized powder, 100% barley young leaf powder (manufactured by Yamamoto Kampo Co., Ltd.) was used. As the blended pulverized powder, the pulverized powder blended with an equal amount of dextrin was used. Granulation was performed by fluidized bed granulation using 400 g of each sample powder.

The fluidized bed granulator was a flow coater (product number FL0-1, Freund Sangyo Co., Ltd.). The granulator was warmed up in advance to 65 ° C. Each sample powder was placed in the raw material container of the flow coater, set in the main body, and then preheated and dried for about 10 minutes. The operating conditions of the flow coater were set to an intake air temperature of 65 ° C. and a spray air pressure of 0.12 kg / cm ² .

  In the granulation step, 80 ml of water was sprayed for about 10 to 25 minutes and then dried for 5 minutes, which was defined as one step. This step was repeated 5 to 8 times, and finally dried for 15 minutes. 20 g of sampling was performed in each step of granulation. The degree of difficulty in granulating each sample powder is shown below.

  The SD powder had poor fluidity in the granulation step, frequent blocking occurred, and it took about 3 hours to complete the granulation operation. Since SD powder is a natural product, it may be very difficult to produce a granulated product depending on the lot, and it is very difficult to handle as a granulated powder.

  The compounded SD powder may have poor fluidity in the granulation step and may cause blocking unless the adjustment of the granulation device is properly operated, but it was possible to produce a granulated product. However, like the SD powder, it takes about 3 hours to complete the granulation operation, and it is difficult to handle as the granulation powder, and a skilled technique is required.

  Since the pulverized powder has the property of returning to the original fine powder in the drying step, it was not possible to finally produce a granulated product. Regarding the blended pulverized powder, since dextrin is a proper binder, a granulated product can be easily produced, and it is very easy to handle as a granulated powder.

[Evaluation of fluidity improvement in granulation process]
It was found from the results of Example 1 that the barley young leaf squeezed dry powder was difficult to granulate even if dextrin was added. Based on this result, the inventors examined the use of a fluidity improver in order to improve the fluidity in the granulation process. Up to now, the fluidity improver was generally added after the granulation step, but it is necessary to study the improvement of fluidity in the granulation step by blending the fluidity improver before the granulation operation. went.

  Seaweed Calcium IT-1 (manufactured by Taiyo Kagaku Co., Ltd.) as a flow improver was added to the compounded SD powder of Example 1 so as to have a calcium content of 1% by weight, 3% by weight, 10% by weight, and 30% by weight. What was mixed with was used as a test sample. As a control, blended SD powder containing no seaweed calcium IT-1 was used. In the granulation step, fluidized bed granulation was performed by the same method as in Example 1, and 6 steps were repeated.

  The evaluation of the granulation result is performed by classifying the granules in each granulation step 1 to 6 times, calculating the weight% of the granules having a constant size, which is equivalent to the weight% of the final product having a constant size. The number of granulation steps required to achieve the above was compared. For example, when comparing the number of granulation steps required for the granulated product to occupy 70 wt% to 80 wt% of particles having a size of 75 μm to 180 μm, the smaller the number of granulation steps required, the more efficient This means that the granulated product could be manufactured in a short time.

  The classification test is a JIS standard mesh size of 14 mesh (opening: 1180 μm), 30 mesh (opening: 500 μm), 42 mesh (opening: 355 μm), 60 mesh (opening: 250 μm), 83 mesh (opening) Opening: 180 μm), 100 mesh (opening: 150 μm), 140 mesh (opening: 106 μm), 200 mesh (opening: 75 μm) made of stainless steel sieve.

  When the size of the granulated product is less than 14 mesh and 200 mesh or more, the number of granulation steps in which the ratio (% by weight) of the cumulative amount reaches 87% to 92% is controlled by the compounded SD powder to which Ca is added. Compared with (6 times), both decreased (2 to 4 times), and further decreased (2 to 3 times) in the compounded SD powder sample to which Ca was added by 1 to 3% by weight.

  When the size of the granulated product is less than 14 mesh and 140 mesh or more, the number of granulation steps in which the ratio (% by weight) of the cumulative amount reaches 74% to 76% is controlled by the compounded SD powder to which Ca is added. Compared with (6 times), all decreased (3 to 5 times), and further decreased (3 times) in the compounded SD powder containing 1 to 3 wt% Ca.

  When the size of the granulated product is less than 14 mesh and 60 mesh or more, the number of granulation steps in which the ratio (% by weight) of the cumulative amount reaches 4.7% to 6% depends on the compounded SD powder to which Ca is added. Was decreased (1 to 3 times) compared with the control (5 times), and was further decreased (1 to 2 times) in the compounded SD powder containing 1 to 3 wt% of Ca.

  From the above results, it became clear that the blending of the fluidity improver shortens the time of the granulation step. Up to now, the fluidity improver has been blended for the purpose of improving the fluidity of the granulated product after the granulation operation and preventing caking, but by blending it before the granulation operation, the fluidity in the granulation process is improved. It became clear that work efficiency was improved. Furthermore, it has been clarified that the addition of a fluidity improver also improves the fluidity and prevents caking of the granules of young barley squeezed dry powder, and the handling (storage, storage, Supply, light weight, transportation) have also been confirmed to be improved.
