Description

Technical Field

[0001] The invention relates to the technical field of beer brewing, in particular to a temperature control system. Background Art

[0002] Beer is a fermented wine made from malt and water as the main raw materials, with hops (including hop products) added and fermented by yeast. It contains carbon dioxide and can form foam.

[0003] Temperature control is particularly important in the brewing process, but nowadays, some brewers choose to brew in the right season. However, from wort processing, yeast breeding and fermentation to final cooling, heat is also a catalyst that can accelerate chemical reactions and biological decomposition processes. This principle also applies to the alcohol fermentation process. If the temperature in the fermentation tank is too high (above 35°C), the yeast cannot survive. When the temperature is below 5°C, the yeast will enter a dormant state and alcohol fermentation cannot proceed. The current beer brewing temperature control is usually controlled manually. There is a lack of rapid adjustment and control of temperature changes during the fermentation process, which affects the quality of brewed beer.

[0004] Therefore, the present invention provides a temperature control system to solve the above-mentioned related technical problems. Summary of the invention

The present invention can determine whether the temperature is uniform everywhere, and can also determine whether the internal temperature of the fermentation tank is within the temperature range of the fermentation stage, so as to ensure that the overall temperature distribution of the fermented material is uniform and the fermentation temperature is reasonable. At the same time, the fermentation temperature can be predicted and temperature compensation can be performed in advance at the predicted time, so as to reduce the impact of temperature fluctuations on fermentation and ensure the quality of winemaking.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] Example:

[0049] like Figure 1-Figure 4 As shown, the present embodiment provides a temperature control system, which includes an information collection unit 100, a temperature control unit 200 and a control response unit 300, wherein: the information collection unit 100 is used to collect the temperature in the fermentation tank, the information of the fermentation material and the information of the coolant; the temperature control unit 200 determines the temperature difference in the fermentation tank and predicts the temperature of the fermentation tank according to the received information and the preset information, and compensates the temperature in the fermentation tank according to the predicted temperature, and the temperature control unit 200 is connected to the information collection unit 100; the control response unit 300 is used to control the flow and temperature of the coolant, as well as to set the fermentation parameters and display the received information, and the control response unit 300 is connected to the temperature control unit 200.

[0050] The information of the fermentation material includes material density, material concentration and specific heat capacity of the material.

[0051] In the present embodiment, it should be noted that, during wine fermentation, the information collection unit 100 is used to collect the temperature in the fermentation tank, the information of the fermentation material and the information of the coolant, and the above information is fed back to the temperature control unit 200. After receiving the information, the temperature control unit 200 will first determine the temperature of multiple collection points at the top, middle and bottom of the fermentation tank, as well as the temperature difference between the top, middle and bottom to determine whether the temperature is uniform everywhere, and when the fermentation temperature of the material is uneven, the fermentation material is processed, such as stirring, to ensure that the overall temperature distribution of the fermentation material is uniform, to avoid uneven temperature of the fermentation material, which affects the quality of winemaking.

When it is within the first temperature difference threshold, the average value of each average temperature is calculated again to obtain a secondary average value, and the secondary average value is compared with the preset second temperature difference threshold. If it is within the second temperature difference threshold, no temperature adjustment information is fed back, otherwise, the temperature adjustment information is fed back; real-time temperature prediction and calibration effects are achieved.

[0053] In addition, when adjusting the temperature, the control response unit 300 is used to adjust the flow and temperature of the coolant to achieve an intelligent temperature control effect.

When the fermentation temperature of the material is uneven, the fermentation material is processed, such as stirred, to ensure that the overall temperature distribution of the fermentation material is uniform, so as to avoid uneven temperature of the fermentation material and affect the quality of the wine.
