Abstract

PURPOSE:To obtain instant bean jam having good taste at low cost, by heating, pressurizing, kneading and gelatinizing adzuki beans by a specific food extrusion molding machine, extruding into a small lump state, grinding and processing. CONSTITUTION:A food extrusion molding machine having two shafts set in parallel engaged with screws having a number of threads with different pitches is used as a kneading machine for food raw materials. Adzuki beans, etc., are heated, pressurized, kneaded, gelatinized by the molding machine, then extruded into a small lump state, further ground and processed to give the aimed instant bean jam. By producing the instant bean jam in this way, powdery bean jam can be produced without carrying out drain operation such as astringency removal drain, boiling drain, water bleaching drain, etc., like a conventional method. Consequently, inexpensive powder bean jam containing starchy material to produce so-called TOROMI (kind of sweetness) contained in skin part of beans or inside part of beans having good taste and abundant nutrition can be obtained.

Description

[Detailed description of the invention] <Industrial application field> This invention relates to a method for producing instant red bean paste.

In particular, the present invention relates to a method for producing instant red bean paste by processing raw materials such as red beans into powdered red bean paste using a food extrusion molding machine.

<Conventional technology> Traditionally, powdered bean paste was produced using azuki beans and kintoki.

After soaking the starchy progeny-containing bean necks of cowpeas, peas, green beans, fava beans, green peas, kidney beans, quail, Otebo 2, etc. in water (soaking) - Soaking in J71u water - Steaming and astringent cutting It consisted of the following steps: 1 boiling, 1 boiling, 2 crushing, 1 cutting, 1 soaking, 1 soaking, 1 draining, 1 drying, 1 crushing.

However, in the conventional method, the ``skin'' of the beans, which is rich in flavor and nutrients, is removed during the manufacturing process, and the ``starch'' contained in the beans, which is the source of the so-called ``thickness'', is also removed. It was removed during the ajikiri drainage process, which involves kneading the bean paste. 7. To make the bean paste thicker, other ingredients such as flake starch and arrowroot starch were added to the resulting powdered bean paste.

In addition, if the "starch" removed during the manufacturing process is disposed of in a public river, it becomes a source of pollution.

A large amount of money was required to install a plant to remove starch, which is a source of contamination. In other words, the conventional method requires a large number of processing steps, which results in the loss of the natural flavor of the beans, is time-consuming, and is expensive.

<Problems to be Solved by the Invention> An object of the present invention is to provide a new method for producing instant red bean paste that eliminates the drawbacks of the above-mentioned prior art.

In this invention, as a kneader for kneading one food raw material, a food extrusion molding machine is used, in which two parallel shafts are fitted with a large number of multi-thread screws having different pitches. Drained and dried raw materials such as adzuki beans are introduced into a food extrusion molding machine consisting of two shafts, and in the process of one feed, they are heated, pressurized, kneaded, gelatinized, extruded into small lumps, and then pulverized into powder. By manufacturing the bean paste, we are able to remove the ``skin'' of the beans, which is rich in nutrients, and without removing the ``starch'' contained in the beans, which gives the so-called ``thickness.'' The aim is to provide low-cost instant red bean paste.

〈Means to solve the problem〉 What is the method for producing instant red bean paste according to this invention?

A food extrusion molding machine is used as a kneader for food raw materials, in which a large number of multi-thread screws with different pitches are fitted to two parallel shafts, and red beans, etc. are heated and pressurized in the food extrusion molding machine.・After kneading and gelatinizing, extrude into small lumps,
It is configured to be manufactured by further pulverizing.

〈Operation〉 Patent application No. 178279/1989 filed by the distributor himself: ``Before adding to food, red beans are washed with water and drained.

After the adzuki beans, which are still granular, are gelatinized in their entirety in the "food extrusion molding machine" (they may be dried as appropriate).

It can be extruded into dry small pieces in the form of granules, plates, rods, cylinders, etc. (The dried small pieces are then pulverized into a powder). In other words, the "food extrusion molding machine" does not perform drainage work such as draining water, boiling water, and soaking water as in conventional methods, so the "skin" part of the beans and the beans that are rich in flavor and nutrients are removed. The ``starch'' contained in it that gives it its ``flavor'' is not lost.

<Example> Hereinafter, a method for producing instant red bean paste according to the present invention will be described in detail.

First, the raw material such as red bean grains is washed with water to remove dirt adhering to the surface of the red bean grains, and then drained and dried. Next, a predetermined amount of the drained and dried azuki bean grains as a raw material is put into a food extrusion molding machine, and the food extrusion molding machine No. 1 Food Extrusion Model No. 178279 "Food Extrusion Molding Machine" is used. This machine has (a) a two-axis (shaft) structure, and each shaft rotates in the same direction.

(b) The multi-thread screw fitted to the shaft does not mesh with each other.

(C) Can be replaced with a screw of a different shape.

(d) Screws of different shapes and pitches can be fitted onto the same shaft.

(e) A liquid injection device (a structure for injecting and adding water) is installed.

It has the following characteristics. Therefore, compared to conventional food extrusion molding machines, (i) it can be used for any kind of food raw material by replacing the screw according to the material to be fed and kneaded;

(ii) By exchanging the screws, screws of different shapes and pitches can have the same cooking function, such as steaming or kneading.

It has the following effects.

The "food extrusion molding machine" consists of a material input port, a constant ff1H feeding section with 21 shafts, a kneading cylinder section, a liquid injection device, and an extrusion port. Pulses with high starch content such as red beans are inputted from the material input port, and gradually descend to the constant ff1t'ffi feeding section, and from the fixed amount conveying section, a fixed amount of red beans and other beans are transported in stages to the 9-kuneli cylinder section. . The adzuki beans and the like that are fed into the kneading cylinder in a certain amount are first crushed by various screws fitted on two shafts at the base of the kneading cylinder. The crushed red beans and the like are transported to the center of the kneading cylinder, where they are stirred and kneaded by the rotation of the shaft, and then gradually pressed (pressurized) toward the extrusion port.

When pressurized, it will naturally generate heat. At this time, if heating by rotating the shaft is not sufficient, it may be possible to install a heating device in the external cylinder of the kneading tube to increase the heating temperature. It can be changed into "plate shape", "cylindrical shape", etc. depending on the nozzle attached to the extrusion port of the "food extrusion molding machine". The pregelatinized and dried small lumps of "an" extruded from the extrusion port of the "food extrusion molding machine" are further crushed into a powder by a crusher. In this example, “
It is extruded from the extrusion port of a food extrusion molding machine in the form of dried small lumps, and then the small lumps are further pulverized into powder. However, it can also be extruded from a "food extrusion molding machine" as a gelatinized bean paste without drying.

An (red bean paste) can be used directly as an ingredient in Japanese sweets and the like. The viscosity of the bean paste can be adjusted by adding water from a pouring device.A production example is shown below.

*Ingredients: Red beans (16kg) (no water added)*
Food extruder operating conditions *Results Under the above conditions, 11.5 kg of powdered bean paste could be produced.

<Effects of the Invention> The method for producing instant red bean paste according to the present invention has the structure as detailed above, and uses astringent drainage, boiling drainage,
In addition to not performing any drainage work such as water washing or drainage, adzuki beans, etc. are directly fed into the "food extrusion molding machine" and only the machine is used to form granules, plates, and rods.

It can be extruded into dry small lumps such as cylindrical shapes, and then processed through a pulverizer to produce powdered bean paste.

It is possible to provide an inexpensive powdered bean paste that does not lose the "skin" part of the bean, which is rich in flavor and nutrients, and the "starch" that gives the so-called "thickness" contained in the bean. Also,
Since "starch" is not removed or discharged, it does not become a source of pollution in general rivers, etc. Furthermore, by pouring hot water into the instant red bean paste made by this manufacturing method, stirring and mixing, and leaving it for about 30 minutes.

It is possible to make ``an'' that is both rich in flavor and high in nutrients. In addition, unlike conventional methods, the "starch" that gives the so-called "thickness" is not lost during the manufacturing process, so it can be used as a "base for oshiruko" without the need to mix in arrowroot powder, Katou flour, etc. I can do it. Furthermore, since it is in powder form, it can be used in small quantities as needed, and has a good shelf life of 2 days, allowing for long-term storage. Also, since it is not a living thing, it does not require special consideration in management.
