Description

  The present invention relates to a method for producing solid coffee, and more particularly to a method for producing solid coffee for solidifying instant coffee.

  Powdered instant coffee can be easily made without the work of extraction in regular coffee. Such powdery instant coffee has the property of being highly water-soluble, but due to this property, there is a problem that powdered instant coffee becomes solid due to the influence of humidity in the air. It was.

  In addition, it has been pointed out that powdered instant coffee spilled from the cup is easy to melt, making it difficult to clean.

  For this reason, in view of the above-mentioned problems, there has been a strong demand for a technique for producing instant coffee that is easily dissolved in hot water and solidified.

The prior art that the applicant of the present application knows at the time of filing a patent is as described above and is not an invention related to a known literature, so there is no prior art information to be described.

  The present invention has been made in view of the strong demand for the conventional technology as described above, and its object is to produce a solid coffee for producing a solidified instant coffee that can be easily dissolved in hot water. Is to provide a method.

  In order to achieve the above object, the invention according to claim 1 of the present invention is that the instant coffee produced by adding an additive to the instant coffee raw material is pulverized, and the instant coffee powder is compressed by a tableting machine. It is what you do.

  The invention according to claim 2 of the present invention is the invention according to claim 1 of the present invention, wherein the tablet additive is a release agent and a disintegrant.

  The invention according to claim 3 of the present invention is the invention according to claim 2 of the present invention, wherein the tablet release agent is a 2% by weight water-soluble ester.

  Moreover, the invention according to claim 4 of the present invention is the invention according to any one of claims 2 or 3 in the present invention, wherein the tablet disintegrant is 5% by weight or less of saccharide. It is a thing.

  Further, in the invention according to claim 5 of the present invention, in the invention according to claim 4 of the present invention, the disintegrant is agar powder, gluconannan, pregelatinized starch or carboxymethylcellulose calcium. It is a thing.

  The invention according to claim 6 of the present invention is the invention according to any one of claims 1, 2, 3, 4 or 5 of the present invention, wherein the size of the instant coffee powder is 40 to 50 mesh.

  The invention according to claim 7 of the present invention is the mold according to any one of claims 1, 2, 3, 4, 5 or 6 of the present invention. The surface temperature is set to 60 ° C. or lower.

  The invention according to claim 8 of the present invention is based on the tableting machine according to any one of claims 1, 2, 3, 4, 5, 6 or 7 of the present invention. The pressure at the time of tableting is set to 600 kg / cm.

  Since this invention is comprised as demonstrated above, there exists the outstanding effect that the solidified instant coffee can be manufactured.

  Hereinafter, an example of an embodiment of a method for producing solid coffee according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a flow chart showing the production process of solid coffee according to the present invention. In this embodiment, for example, a tableting machine manufactured by Kikusui Seisakusho is used to solidify the powder into a certain shape.

  First, a disintegrating agent for facilitating dissolution of instant coffee solidified by a tableting machine and a water-soluble ester releasing agent for improving peeling from the mold of the tableting machine. It is added to an instant coffee raw material (hereinafter, “instant coffee raw material” is simply referred to as “raw material”) and mixed by a mixer.

  This disintegrant must be added to dissolve in solidified instant coffee hot water that becomes difficult to dissolve in hot water because it is molded at high pressure, and is basically water-soluble and tasteless and odorless. Use one that does not affect

  Specifically, the addition amount is 5% or less of the raw material weight, and agar powder, glucomannan, pregelatinized starch, carboxymethylcellulose calcium, or saccharides other than those described above are used. The solidified instant coffee produced according to the present invention by using such a disintegrant is approximately 1/4 to 1/1 when using agar powder or glucomannan as compared to the case without using the disintegrant. In the case of using the pregelatinized starch or carboxymethyl cellulose calcium, the solution is dissolved in about 1/2 time as compared with the case where the disintegrant is not used.

  The amount of the release agent added is 2% of the weight of the raw material, and if it is lower than 2%, there is a problem in taking out from the mold, and if it is higher than 2%, the taste of the manufactured instant coffee is solid. It will change.

  The size of powdered instant coffee produced from the raw material to which the release agent and disintegrant are added is set to 40 to 50 mesh in order to facilitate feeding into a tableting machine.

  Next, the powdered instant coffee produced in the above process is fed into a mold of a tableting machine for tableting to produce solidified instant coffee.

  At that time, the rotation of the rotating plate is set to a medium speed rotation, the pressure at the time of tableting is adjusted to 600 kg / cm, and the mold surface temperature is adjusted to be kept at 60 ° C. or lower. When the pressure at the time of tableting is higher than 600 kg / cm, the produced instant coffee is not easily dissolved, and when the pressure at the time of tableting is lower than 600 kg / cm, the instant coffee is not solidified.

  When the surface temperature of the mold exceeds 60 ° C., the surface of the manufactured instant coffee is collapsed and heat sagging occurs. For this reason, it is necessary to make room and humidity constant in the place where the tablet press is placed so that the surface temperature of the mold does not vary as much as possible.

Thus, by solidifying instant coffee, the amount of coffee instantly clarified as one cup of solidified instant coffee, and cleaning is easy when dropped because it is large. .

  Furthermore, since the area where the coffee particles are in contact with the air is small and there is no air circulation, moisture can be prevented and the flavor can be confined inside, so that the effect that the flavor is hardly affected by the moisture in the air can be obtained.

  Moreover, when it solidifies with a tableting machine, it has a secondary roasting effect by heat-processing. This secondary roasting effect has an effect of eliminating the miscellaneous taste mixed in the raw material although the roasting degree is shallow, and the instant coffee produced is easier to drink.

In the above-described embodiment, the tableting machine manufactured by Kikusui Seisakusho was used, but it is of course not limited thereto. For example, a tableting machine manufactured by Hata Seisakusho may be used, Other tableting machines may be used.

  INDUSTRIAL APPLICABILITY The present invention can be used as instant coffee that can be carried outdoors and can be easily tasted.

FIG. 1 is a flowchart showing a production process of solid coffee according to the present invention.
