Description

Description: TECHNICAL FIELD The present invention relates to a method and an apparatus for producing high-quality ground pepper with an aroma or the like.

(Prior Art) Conventionally, in order to obtain pulverized spices such as pepper, these holes have been pulverized to a final particle size in one step by a high-speed pulverizer such as a pin mill. However, this method not only has problems such as a lack of uniformity of grinding and a decrease in grinding efficiency, but also requires a large amount of energy at the time of grinding to heat the spices. It was difficult to obtain a good ground spice.

In addition, in a field other than spices, a multi-stage pulverization technique using a roll machine is known. For example, JP-A-63-166442
In the two-stage pulverizing method and apparatus using a roll mill and another mill downstream thereof, the amount of coarse particles generated during sieving is branched and returned to the roll mill and the second mill. The brittle material 2 is controlled so that the sum of the amount of new material and the amount of coarse particles is kept constant and the distribution of the amount of coarse particles to the two branch flows is controlled so that the driving force of the roll mill is constant. A step grinding method and apparatus is disclosed. However, even in such a two-stage pulverization, in the prior art, when a large amount of energy is applied at the time of pulverization, the spice is heated, and by this heat denaturation, it is possible to obtain a pulverized spice with good quality such as aroma and flavor. ,was difficult.

(Problems to be Solved by the Invention) In view of the above-mentioned problems of the prior art, the present invention provides a method and a method for producing a high-quality ground spice having excellent aroma and flavor from a hole such as black pepper and white pepper. It is intended to provide a device.

(Means for Solving the Problems) The present invention is to reduce the heating energy of the pepper by reducing the energy at the time of crushing the pepper hole into fine particles stepwise under specific conditions using a roll machine. It has been made based on the finding that the above object is effectively achieved.

That is, according to the present invention, a first crushing step of crushing the pepper hole using a roll machine so that the crushed material having a particle size distributed in a particle size range of 300 to 1500 μ becomes 40 to 85% by weight;

(Action) In the present invention, by performing the first pulverization step under specific conditions before the final pulverization, it is possible to pulverize the pepper to a state in which the pepper can be easily pulverized to the final particle size in a state where heating of the pepper is relatively prevented. it can. Therefore, the final pulverization of the pulverized material can provide excellent pulverization suitability and efficiency, and can obtain finely ground pepper excellent in uniformity of particle size, aroma, and flavor.

(Example) Hereinafter, an example of an apparatus for producing ground pepper that can suitably implement the present invention will be described with reference to the drawings.

A hole storage device 10 is provided for storing a pepper hole, which is a material of ground pepper, and supplying the pepper hole to the grinding step.

The first roll machine 1 is provided downstream of the hall storage device 10. The first roll machine 1 is for slightly pulverizing the pepper hole supplied from the hole storage device 10, and rotates at different speeds in directions indicated by arrows d1 and d2, respectively.

It is desirable to drive by the meshing method of p).

A first shifter 21 is provided downstream of the first roll machine 1. The first shifter 21 is for sifting the pepper pulverized by the first roll mill 1 and has a predetermined mesh, that is, a sieve having an opening dimension. The mesh of the sieve is appropriately determined depending on the desired particle size of the final product.
300300 μm.

Downstream of the first shifter 21, a first product passage 3 for passing the pulverized material that has passed through the shifter and a first pulverized material passage 4 for passing the pulverized material remaining in the shifter are provided.

The second roll mill 2 is provided downstream of the first shifter 21 via the first pulverized material passage 4. The second roll machine 2 is for further pulverizing the pulverized material remaining in the first shifter 21. Two rollers rotating at different speeds in directions indicated by arrows d3 and d4, respectively. 2A, 2B. The rollers 2A and 2B can adjust the roller gap similarly to the first roll machine 1, and have the same tooth shape and meshing system.

A second shifter 22 is provided downstream of the second roll machine 2. The second shifter 22 is for sifting the pepper pulverized by the second roll mill 2, and has a predetermined mesh, that is, a sieve having an opening size, like the first shifter 21.

Downstream of the second shifter 22, there is provided a second product passage 5 for passing the pulverized material passing through the shifter and a second pulverized material passage 6 for passing the pulverized material remaining in the shifter. Second crushed material passage 6
Supplies the pulverized material to the second roll machine 2 again.

The pulverized material that has passed through each shifter is sent through a first product passage 3 and a second product passage 5 to a product storage device 11 provided downstream of the present device. The product storage device 11 is for storing ground pepper having a desired particle size as a product.

Next, a method for producing ground pepper using the above-described grinding apparatus will be described. This method for producing ground pepper comprises a first grinding step and a second grinding step.

The first pulverizing step includes the first roll mill 1 and the first shifter 21.
Done by First, the pepper holes (hole diameter of about 3000 to 5000 μ) stored in the hole storage device 10 are supplied to the gap between the rollers 1A and 1B of the first roll machine 1. Then, the pepper hole is adjusted, for example, by rollers 1A and 1B adjusted to a gap of 0.5 mm so that the crushed material having a particle size distributed in a particle size range of 300 to 1500 μ becomes 40 to 85%, preferably 50 to 75%. Crushed. Next, the ground pepper is supplied to the first shifter 21 and sieved. The ground material that has passed through the sieve is supplied to the product storage device 11 through the first product passage 3.

The pepper hole is pulverized by the first roll machine 1 so that the pulverized material is distributed in the above-mentioned relatively large particle size range in a large amount, so that heat generated by pulverization energy is prevented as much as possible. Pulverization is performed by a two-roll mill 2 so that desired pulverization can be achieved.

Next, the second grinding step is performed by the second roll mill 2 and the second shifter 22. First, the pulverized material remaining in the first shifter 21 is supplied to the gap between the rollers 2A and 2B of the second rolling machine 2. For example, a roller adjusted to a gap of 0.03 mm
According to 2A and 2B, the pulverized product having a particle size distributed in a particle size range of 100 to 300 μ is pulverized so as to have a particle size of 25 to 75%, preferably 40 to 60%. Next, the ground pepper is supplied to the second shifter 22 and sieved. The ground material that has passed through the sieve is supplied to the product storage device 11 through the second product passage 5.

In the first pulverization step, the pulverized product pulverized to a finer particle size to some extent while preventing generation of heat is pulverized in the final second step to a particle size of a product which is required to be extremely homogeneous without adversely affecting aroma and the like. be able to.

It is preferable that the pulverization treatment in the first and second pulverization steps is performed in a substantially sealed state. Here, the “substantially sealed state” refers to a state in which the flavor of pepper can be prevented from being deprived by wind force during the grinding. In addition, the crusher uses forced cooling or natural cooling to reduce the crushing temperature to 45
C., preferably not more than 40.degree. That is, when the pulverization temperature exceeds 45 ° C., the aroma of pepper tends to volatilize or deteriorate.

As described above, the pulverized pepper that has been pulverized to the desired particle size and stored in the product storage device 11 is a product.

Next, an embodiment in which a pepper hole is pulverized using the apparatus for producing pulverized pepper shown in FIG. 1 will be described. A dried hole of pepper stored in the hole storage device 10 (grain size of about 3000 to
5000 μ) was supplied to the first roll machine 1 in a fixed amount, whereby a ground pepper product was obtained. The pulverized product contained about 60% of particles having a particle size ranging from 300 to 1500 μ. The crushed product was sent to a first shifter 21 having an opening of 250 μm to be sieved, and the product passed through the sieve was sent to a product storage device 11.
In addition, the weight of what passed through the sieve corresponds to about 30% of the weight of the pepper hole.

What was left in the first shifter 21 was supplied to the second roll machine 2 in a fixed amount, whereby a pulverized product was obtained. In the pulverized material,
45% of particles having a particle size distributed in the range of 100 to 300 μ particle size were contained. After being processed by the second roll mill 2 together with about 5% of the pulverized material having the above particle size range passed through the first shifter 21, about 50% of the pepper hole was pulverized in this particle size range. The pulverized product was sent to a second shifter 22 having an aperture of 250 μm to be sieved, and the product passed through the sieve was sent to a product storage device 11. 2nd shifter 22
Was left to the second roll machine 2 again.

The product had the preferred flavor of pepper and was of uniform particle size.

The present invention is significant in performing a first pulverizing step under the above conditions before final pulverization. However, a step of pulverizing to a larger particle size before the first step or a step of pulverizing to a particle size between these pulverized particle sizes between the first and second pulverizing steps is performed. And further includes performing multi-stage roll grinding.

Further, as shown in the Examples, it is also included in the present invention that a shifter is provided between each pulverization step to separate pepper having a desired particle size by pulverization. The pulverized material remaining in each shifter can be re-supplied to an arbitrary roll machine in front.

Thus, it is possible to obtain fine-grained pepper having even more uniform particle size. However, if the pulverization is performed in too many stages, the aroma and flavor of the pepper are adversely affected. Therefore, two-stage pulverization is particularly desirable in order to maintain these and to obtain a uniform particle size. Thereby, the desired high quality ground pepper can be obtained with a simple process and at low cost.

(Effect of the Invention) By crushing the pepper hole stepwise under specific conditions using a roll machine, it is possible to crush the pepper hole to the final particle size while preventing the generation of heat from the pepper during the crushing. Therefore, the crushed pepper thus crushed is of high quality with excellent aroma. In addition, uniform ground pepper can be obtained with a fine particle size.
