Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a bread dough temperature control device for controlling the temperature of bread dough in a mixer used in a kneading step in a bread making process.

As is well known, in the bread-making process, water is added to raw materials such as flour, yeast, and salt using a mixer and kneaded to evenly mix the raw materials and ensure that the flour absorbs sufficient water. There is a kneading process that softens, stretches, and binds the protein and gluten contained in flour.

One of the important issues in this process is the adjustment of the kneading temperature of the bread dough, which affects the fermentation of the bread dough.

Factors related to this temperature adjustment include powder temperature, water temperature, dust, room temperature, kneading rising temperature, and middle dough temperature during main kneading.
It is known as a rule of thumb that the following relationships exist.

Among these factors, the dough temperature is 25
In the range of ~29C, the optimal temperature for each type of dough is known in advance, and the flour temperature, room temperature, and dough temperature are determined by measurement, and the temperature at which the dough is kneaded and kneaded by applying power to the mixer is also under the same conditions. It is also known empirically how much the temperature will rise under these conditions.

Therefore, the optimum dough temperature is determined by changing the water temperature dust according to the temperature of other various factors.

Equations (1) and (2) above can be rearranged for water temperature dust as follows.

(3) Water temperature dust of medium dough kneading water temperature dust - (bread dough temperature - kneading rising temperature) x 3 - (flour temperature 10 room temperature) (4) Water temperature dust of main kneading water temperature dust = (bread dough temperature - kneading rising temperature) x 4- (Powder temperature, room temperature, seed temperature) In the past, all of these factors were measured and calculated by the worker, and the temperature of the water stored in the water tank was raised until it reached the calculated value. The kneading process using a mixer is very complicated, and only a skilled person can do the work in a short amount of time. However, there are slight differences in the measurement of various factors and the order of operations, making it difficult to obtain uniform bread dough.

This invention was made in view of the above circumstances, and the temperature measurement and calculation of various factors are automatically performed, and the water is heated until it reaches a predetermined water temperature calculated by a water temperature control device installed in the aquarium. It is an object of the present invention to provide a bread dough temperature control device that controls the temperature of bread dough in a mixer by raising or lowering the temperature and then feeding the dough into a mixer containing raw materials and mixing them.

An embodiment of the present invention will be described below based on the description of the drawings.

In the figure, 1 is a room temperature sensor, 2 is a powder temperature sensor, and 3 is a powder temperature sensor.
are intermediate temperature sensors in this kneading system, which each sense a temperature in the range of 5 to 400 C, convert it into a DC current of, for example, 4 to 20 mA by the respective converters 4 and 5.6, and send it to the amplifier 7. After amplifying the signal, the signal is input to the CPU 9 through the A/D converter 8.

Each circuit between each converter 4, 5.6 and the amplifier 7 includes a relay switch Ry1. Ry2. Ry3 is provided respectively.

Further, the CPU 9 is configured to be able to input bread dough temperature and kneading temperature rise through a keyboard 10, and is also provided with a memory 11 for storing these input data and calculation results. A display 12 is connected to the CPU 9 and is capable of outputting the temperature, automatically input temperature values for each factor, and temperature values manually input from the keyboard 10 as required.

Furthermore, the CPU 9 stores calculation procedure programs for formulas (3) and (4), and each sensor 4,
The data of various factors input from 5 and 6 as well as the data input from the keyboard 10 are calculated, and the water temperature as a result of the calculation is outputted to V/V through the analog output device 13, and the converter 14 outputs a current of, for example, 4 to 20 mA. The temperature controller 15 changes the strength of the current to an electric heater (not shown) provided in the water tank and connected to a power source (not shown). By converting, the amount of heat generated by the electric heater is controlled and the temperature of the water in the tank is raised to the calculated water temperature.

The temperature control device 15 for the aquarium is also equipped with a cooler connected to a power source (not shown), if necessary, so that it can be cooled down if the water in the aquarium rises more than necessary. It looks like this.

Between the keyboard 10 and the CPU 9 and between the display 12 and C
An interface 16 is provided between each PU9.

The operation of this invention having the above configuration will be explained as follows.
First, by operating a switch not shown in the figure, the relay switch Ry1 is turned on, and the room temperature measured by the room temperature sensor 1 is converted to the strength of the current through the converter 4, and after being amplified by the amplifier 7, it is converted to a % converter. 8 and is temporarily stored in the memory 11.

When the measurement of the room temperature is completed, the relay switch Ry1 is cut off and the relay switch Ry2 is automatically turned on. Similarly, the powder temperature is measured by the powder temperature sensor 2 and stored in the memory 11, and the relay switch Ry2 is cut off.

This disconnection then turns on relay switch Ry3,
Similarly, after the temperature of the middle dough is measured and stored in the memory 11, the relay switch Ry3 is turned off, but this temperature of the middle dough is measured only in the case of main kneading, and when this temperature is measured, the above formula ( When the calculation formula (4) is called and the temperature of the armor type is not measured, the above-mentioned formula (3) is called.

Next, after the measurement of these various factors and storage in the memory 11 is completed, or at the same time as these automatic measurements, the optimum dough temperature and kneading temperature rise are determined according to the type of dough to be kneaded, which is input from the keyboard 10. After storing it in the memory 11, the water temperature is calculated in the CPU 9 according to the equation (3) or (4), and immediately sent to the □1 converter 14 through the analog output device 13, where the current strength is determined, for example, 4 to 20 mA. After the current is converted into a current, the temperature of the water in the water tank is calculated by controlling the amount of heat generated or the amount of cooling of the electric heater or cooler of the temperature control device 15 installed in the water tank in proportion to the strength of this current. temperature.

Note that the rising temperature during kneading does not change under the same conditions, so when kneading bread dough over and over again,
If the first input data is stored, this input data can be used from the second time onward, which saves the trouble of inputting data each time kneading is performed.

In this way, when the temperature-controlled water is introduced into the mixer and mixed with the raw materials, kneading can be performed according to the input dough temperature.

As is clear from the above description, the bread dough temperature control device of the present invention adjusts the temperature of water mixed with raw materials in order to control the temperature of bread dough in the mixer, and for this purpose, the temperature of the water is determined. Various factors such as flour temperature, room temperature, and dough temperature during main kneading are automatically measured and stored in the memory 11 of the CPU 9, and then the dough temperature value and the kneading temperature rise entered from the keyboard 10 are measured automatically. Calculate the water temperature by calculating the value along with the above factors according to a calculation formula program based on empirical rules,
Water temperature control device 1 installed in the aquarium until this water temperature is reached
Water whose temperature has been adjusted by operating the electric heater or cooler No. 5 is fed into the mixer and mixed with the raw materials, thereby controlling the temperature of the bread dough.

Therefore, unlike in the past, there is no need to measure each factor each time you knead, and there is no need to calculate the measured data one by one, which saves time and improves work efficiency. Even workers can easily perform the work, and uniform bread dough can be obtained even by different workers.
