In the process of the water-removing and carding process, the tea leaves are complex to stir. For example, summarized by the association of Longjing tea leaves, the tea is prepared by frying in a smooth, specially-made iron pan with manually-operated frying techniques, which include shaking, lapping, , pressing, throwing, grasping, pushing, buckling, pressing, grinding and other ten major techniques. Therefore, the tea leaves are not heated constantly, but heated periodically and cooled repeatedly, and the heating process is complex.

The tea leaves fried manually are generally complete and bright, the taste is relatively pure, the tea type fried by a machine is not very good, and the tea leaves can be broken or overfire due to the fact that the degree of the tea leaves cannot be controlled. And because the machine stir-fry tea leads to the heated process of tealeaves comparatively simple, the tealeaves quality is than stir-fry system by hand poor. Therefore, it is necessary to develop a tea heating device capable of extracting the heating characteristic of the manually-fried tea, which is used for improving the heating characteristic of the electrically-fried tea to make the electrically-fried tea more approximate to the heating characteristic of the manually-fried tea, improving the quality of the electrically-fried tea and avoiding the excessive heating of the tea.

The resistor R1 is a fixed value resistor, and is suitable for selecting a resistor with small temperature drift, although the resistor R1 and the heat conduction cap 4 are shown to be positioned on one side of the heat insulation board 9 in the figure, the best mode is that the resistor R1 is arranged on the other side of the heat insulation board 9, the resistance value of the thermistor Rr can be calculated by detecting the voltage at the two ends of the thermistor Rr, and the temperature value of the thermistor Rr can be obtained according to the characteristic curve of the thermistor Rr.
Example two:
the embodiment is further improved on the basis of the first embodiment. As shown in fig. 3, the heat insulation housing 1 is in a flat column shape, i.e. the width of the heat insulation housing 1 is more than 2 times of the height, a turn-over detection box is installed in the heat insulation housing 1, the turn-over detection box has a cavity 12 in a rectangular parallelepiped shape, the length of the cavity 12 is more than 3 times of the height, the height of the cavity 12 is in the same direction as the height of the heat insulation housing 1, a pair of contacts 11 are embedded in both bottom surfaces of the cavity 12, a conductive block 13 is placed in the cavity 12 and is basically abutted to the inner wall of the cavity 12, one pair of contacts 11 in one bottom surface is respectively connected with a resistor R3 and one end of a thermistor Rr3, the other end of a resistor R3 is connected with the other end of the thermistor Rr3, one end of a resistor R0 and an ith I/O pin of the single chip microcomputer 7, the other end of the resistor R0 is connected with a jth I/O pin of the single chip microcomputer 7, one pair of contacts 11 in the other bottom surface is respectively connected with a resistor R4 and one end of the thermistor Rr4, the other end of the resistor R4 is connected with the other end of the thermistor Rr4 and the kth I/O pin of the singlechip 7, a known voltage difference exists between the jth I/O pin and the kth I/O pin, voltage digital-to-analog conversion can be performed between the ith I/O pin and the kth I/O pin, the thermistor Rr3 and the thermistor Rr4 are attached to two surfaces of the heat insulation shell 1 respectively, and the difference value of the resistance values of the resistor R3 and the resistor R4 exceeds the maximum working resistance value of the thermistor R3 and the thermistor Rr 4. The working mode is as follows: a known voltage difference exists between the jth I/O pin and the kth I/O pin, the resistance value of the resistor R0 is known, the resistance value of the resistor R0 is insensitive to temperature change, and voltage digital-to-analog conversion can be carried out between the ith I/O pin and the kth I/O pin, namely voltage division can be measured, so that the total resistance value Rs formed by the resistor R3, the resistor R4, the thermistor Rr3 and the thermistor Rr4 can be measured. The thermally insulated housing 1 is in the form of a flat column, i.e. the electrically conductive block 13 is kept in contact with one of the two bottom surfaces for the majority of the time, i.e. the electrically conductive block 13 is connected to a pair of contacts for the majority of the time. When the conductive block 13 is not in contact with any contact 11, the resistance value Rs = Rr3+ Rr4, when the conductive block 13 is connected with a contact connected with R3, the resistance value Rs' = Rr3// R3+ Rr4, the resistance value of the thermistor Rr3 can be obtained by combining the two formulas, and the current temperature of the thermistor Rr3, namely the temperature of one bottom surface of the heat insulation shell 1 can be known according to the resistance value characteristic of the thermistor Rr 3. Similarly, when the conductive block 13 is connected to the contact point to which R4 is connected, the resistance value of the thermistor Rr4, that is, the temperature of the other bottom surface of the heat insulating case 1 can be obtained. Although the contact between the conductive block 13 and the pair of contacts cannot be directly obtained, a mode of calculating two groups of contacts can be adopted, and the difference value of the resistance values of the resistor R3 and the resistor R4 exceeds the maximum working resistance values of the thermistor Rr3 and the thermistor Rr4, so that an incomprehensible solution can be generated, the solution is generated when the temperature of the heat insulation shell 1 is too high or too low, and the contact with the conductive block 13 can be accurately obtained by excluding the solution. Further, it is known which bottom surface of the heat insulating casing 1 is facing downward at present, and the temperature of the bottom surface is obtained. The contact frequency of the conductive block 13 is alternated between the contact pairs, so that the rolling frequency of tea leaves in the tea frying process can be reflected, and further more characteristics of manual tea frying are extracted.
The substantial effect of the embodiment is as follows: the size of the input type temperature monitor is equivalent to that of fresh tea leaves, the input type temperature monitor can be mixed with the fresh tea leaves, and the input type temperature monitor has the motion characteristic similar to that of the fresh tea leaves in the stir-frying process, so that the heating process of the fresh tea leaves is extracted, and a data base is provided for recovering the heating characteristic of manual tea frying by using electric tea frying equipment.
The above-described embodiments are only preferred embodiments of the present invention, and are not intended to limit the present invention in any way, and other variations and modifications may be made without departing from the spirit of the invention as set forth in the claims.
