Abstract

PROBLEM TO BE SOLVED: To obtain a piece of bread capable of saving a fermentation process after dividing dough and a final prover process thereafter by preparing dough by kneading a dough raw material, making the dough sufficiently fermented one and supplying the resultant dough into at least a pair of opposed nipping devices. SOLUTION: A kneaded dough D1 is prepared by a well-known kneader M in a usual combination of a dough raw material of bread. Next, the kneaded dough D1 is stored and held in a prescribed hot insulation environment of a storing part in a dough box to obtain a fermented dough containing a sufficient amount of air foams. The resultant fermented dough is subjected to periodical repetition of widening and narrowing of a nipping gap in a nipping device and extruded from the device to form a belt-like dough suppressing increase of internal stress of the dough and having elasticity caused from a gel texture without destructing. Then, the belt-like dough is further shaped to form a dough piece and immediately baked without performing a final fermentation to obtain the objective bread.

DETAILED DESCRIPTION OF THE INVENTION

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing bread dough, which omits a final fermentation step which is conventionally performed after final dough formation and before baking, and which is simpler than a conventional bread dough production step. The present invention relates to providing high quality bread to a dining table, which can be a process.

2. Description of the Related Art In a conventional bread manufacturing process, a dough material is kneaded by a mixer (kneading device), and the dough is first mixed.
After fermentation to make a fermented dough, this fermented dough is divided and molded, intermediate fermentation (bench time), molding, and second fermentation (final proofing) are performed to expand it. I am producing it. At this time, the reason for performing bench time and final proofing is to repair the dough division by a machine performed from the batch dough after the preparation of the dough and to repair the breakage of the gel network structure generated at the time of machine molding, and ferment the dough sufficiently. One of the main purposes is to expand and obtain sufficient volume by firing. In other words, during the dough preparation for kneading the dough ingredients, the dough becomes an elastic body that generates a network structure of a gluten protein gel of flour and expands during baking. Since the elastic structure of the dough is broken by the input of, it was necessary to go through a bench time in an environment where the dough can be fermented in order to repair it. Furthermore, since the gel structure is destroyed by the mechanical input in the subsequent molding step, it is a conventional practice to provide a second fermentation step (final proofing) to repair the gel structure. Further, it was necessary to add a dough improving agent such as potassium bromate to the dough in advance.

In the conventional bread making process, the present invention requires the bench time and the final stove as described above. This is an invention in which the subsequent fermentation step (bench time) and the subsequent final proofing step can be omitted, and more excellent bread can be obtained.

SUMMARY OF THE INVENTION According to the present invention, an excellent bread production is achieved by omitting the final boiler before baking the molded dough pieces, greatly shortening the baking process from preparation of the dough to baking. Can be performed. By omitting the conventional final boiler and bench time before baking, it is possible to bake a taste-excellent bread as well as the boiler which has been conventionally required two or three times in the bread manufacturing process. (Fermentation apparatus) can be completed in a single operation, so that the process can be largely labor-saving. According to the method for producing bread of the present invention, in the invention according to claim 1, dough is prepared by kneading bread dough materials, storing the dough in a container, and sufficiently fermenting in a warm environment. Supplying the dough to at least one pair of opposing pressing devices, pressing the dough by repeatedly expanding and reducing the opposing interval of the pressing device, and discharging the dough from the lower outlet of the pressing device. It is formed into a belt shape, cut into predetermined dimensions to produce a piece of dough of a predetermined shape, and the dough piece can be fired without being fermented again. In the invention described in claim 2, in the invention described in claim 1, the pressure device is a roller group including a plurality of pressure rollers arranged in parallel in a vertical direction, and feeds each pressure roller. It is characterized by being configured to be rotatable in each direction. After the kneaded dough kneaded from the bread dough material is sufficiently fermented in advance in a warm environment, it is formed into a band-shaped dough while periodically expanding and reducing the interval of pressing by a pressing device, and discharging. is there. The dough pieces obtained by cutting the band-shaped dough formed in this way into a predetermined shape can be baked immediately without obtaining another fermentation because bubbles are sufficiently retained, and a good-quality bread can be obtained. it can.

BEST MODE FOR CARRYING OUT THE INVENTION In the method for producing bread according to the present invention, kneaded dough is prepared by a well-known kneading apparatus by mixing dough ingredients in a conventional manner. Next, the kneaded dough is stored and allowed to stand in a predetermined heat retaining environment to produce a fermented dough sufficiently containing air bubbles. The dough, which is obtained by discharging the fermented dough by repeatedly expanding and contracting the pinching interval periodically by a pinching device, suppresses an increase in the stress inside the dough, and forms it into an elastic band-shaped dough that does not destroy the gel structure. Can be. Next, the band-shaped dough is cut into a predetermined size or further formed into a dough piece, which is immediately baked without performing final fermentation.
