Description

Technical Field

[0001] The invention belongs to the technical field of wine making, and in particular relates to a wine cellar temperature measuring device with ambient temperature compensation and a use method thereof. Background Art

[0002] In the fermentation process of liquor production, the fermented grains are fermented in the cellar, and after a period of time, the grains are converted into alcohol. The fermentation temperature of the fermented grains is the main indicator to reflect the fermentation status of the fermented grains.

[0003] Considering food safety and sealing, the current instrument for measuring the fermentation of fermented grains in the cellar usually arranges multiple temperature sensors in a stainless steel pipe, such as three temperature sensors for the "upper layer, middle layer, and lower layer". The length of the stainless steel pipe is usually 2 to 3 meters. In order to ensure that the stainless steel pipe has sufficient strength to be inserted into the fermented grains, the wall thickness is usually 1 to 1.5 mm, and the outer diameter of the pipe is 20 mm. In winter, the ambient temperature is low, the temperature of the fermented grains in the cellar is high, and the measurement of the "upper layer" temperature will become inaccurate. This is caused by the heat conduction of the stainless steel pipe. The thicker the pipe wall, the thicker the pipe diameter, and the greater the temperature gradient in the fermented grains, the more serious the impact. In severe cases, the measurement deviation of the "upper layer" temperature will exceed 4°C. Summary of the invention

[0025] The present invention is further illustrated below in conjunction with specific examples. The examples are implemented based on the technical solutions of the present invention. It should be understood that these examples are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0026] like Figure 1 and 2 As shown, the present invention provides a wine cellar temperature measuring device with ambient temperature compensation, including a temperature measuring instrument head 1, a detection tube 2 is fixedly connected to the lower side of the temperature measuring instrument head 1, and the detection tube 2 includes an outer tube body 3, an inner rod 4, a filling layer 5 and a plurality of temperature sensors. Among them, the outer tube body 3 is preferably a stainless steel outer tube body. The inner rod 4 is arranged at intervals inside the outer tube body 3. The inner rod 4 is required to have a large strength and poor thermal conductivity, and preferably a glass fiber inner rod is used. The filling layer 5 is arranged between the outer tube body 3 and the inner rod 4. The filling layer 5 is preferably an elastic foam filling layer, which can be directly bonded and fixed to the outside of the inner rod 4. Several temperature sensors are arranged on the filling layer 5, which are preferably bonded to the filling layer 5. A main control board is provided in the temperature measuring instrument head 1, and the main control board is respectively connected to several temperature sensors through signal lines 6, so that the collected signals are sent to the main control board.

[0027] There are preferably three temperature sensors in the embodiment of the present invention, namely an upper temperature sensor 7, a middle temperature sensor 8 and a lower temperature sensor 9. The upper temperature sensor 7, the middle temperature sensor 8 and the lower temperature sensor 9 are arranged in sequence from top to bottom.

[0028] In order to facilitate the on-site temperature check, a temperature display 10 is preferably provided on the outside of the temperature measuring instrument head 1, and the temperature display 10 is connected to the main control board. The temperature display 10 preferably adopts a segment code liquid crystal display. The main control board preferably includes a single chip microcomputer connected to the temperature display 10, and the single chip microcomputer preferably adopts an STM32 single chip microcomputer. In order to facilitate the signal transmission, the single chip microcomputer is also connected to a communication module, and the communication module preferably adopts a LORA module. A lithium battery is also provided in the temperature measuring instrument head 1 to provide the power required for the operation of the device, and the lithium battery preferably adopts a 18650 lithium battery.

[0029] For ease of use, a handle 11 is fixed between the temperature measuring instrument head 1 and the detection tube 2. The handle and the detection tube 2 are arranged in a T shape. When in use, the handle 11 is held with both hands to facilitate inserting the detection tube 2 into the wine mash in the cellar.

[0030] Based on the above embodiments, those skilled in the art can understand that the present invention also provides a method for using the above wine cellar temperature measurement device with ambient temperature compensation, including:

[0031] The detection tube 2 is inserted into the fermented grains in the cellar, and the upper temperature sensor 7 is arranged 30 to 80 cm below the cellar cap 12.

[0032] A high-precision temperature sensor 13 (such as a glass thermometer or a capillary electronic thermometer) is arranged at a distance of 2 to 5 cm on the horizontal plane of the upper temperature sensor. After the set time is reached, the measured temperature value T1 is read.

[0033] The ambient temperature T2 at this time and the temperature T3 collected by the upper temperature sensor 7 are obtained. The ambient temperature T2 is collected by the ambient temperature sensor 14, and the ambient temperature sensor 14 can be arranged inside or outside the temperature measuring instrument head 1.

[0034] The value of the correction coefficient K is calculated according to T1=T3+K×(T3-T2).

[0035] The calculated correction coefficient K is used to correct the temperature collected by the upper temperature sensor 7. Specifically, in the subsequent use process, the corrected temperature = T3 + K × (T3-T2). It should be noted that when the position of the upper temperature sensor 7 relative to the cellar cap does not change, the above-calculated correction coefficient K can be used all the time. If the position of the upper temperature sensor 7 relative to the cellar cap changes, the correction coefficient K needs to be recalculated.

[0036] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
