Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of color-protecting devices of low-temperature baking of medicine-food homologous pigment. BACKGROUND

[0002] The existing electric heating constant temperature drying generally has the defect of "constant temperature waiting time", that is, when the temperature reaches the set temperature, although the drying temperature is set at the designed constant temperature by the temperature setting button, due to the thermal inertia, there is about half an hour of thermal inertia temperature rise phenomenon before the temperature in the drying chamber remains unchanged, i.e., remains constant, and then the temperature becomes constant. This half-hour thermal inertia temperature rise phenomenon is called "constant temperature waiting time" (the temperature difference during this period is called "constant temperature waiting temperature rise"). For most dried materials that require low temperature or have little change in properties or are acceptable within a short period of time due to temperature changes, such as glassware, ceramic products, steel products, etc., "constant temperature waiting time" does not have a negative impact. However, for materials that require high color and taste and are easily affected by temperature changes, "constant temperature waiting time" is a problem that cannot be avoided and is not desirable. For example, medicine-food homologous medicines (food) and tea. Therefore, people have adopted double-layer high-temperature baking boxes provided by the utility model patent with the authorization announcement number CN 204007059 U or precision baking machines provided by the utility model patent with the authorization announcement number CN203262166U. Although these methods achieve better results in terms of uniform heating and low-temperature long baking, they still cannot overcome the negative impact of "constant temperature waiting time". In particular, for materials that require low baking temperature to preserve pigments well, the high temperature caused by "constant temperature waiting time" for half an hour can seriously affect the properties of the materials and result in low pigment retention rate and low product quality. CONTENT OF THE UTILITY MODEL

[0003] The utility model aims to provide a color-protecting device for low-temperature baking of medicine-food homologous pigment, which can effectively suppress the obvious changes and unevenness of baked materials caused by "constant temperature waiting temperature rise" during "constant temperature waiting time".

[0004] To achieve the above-mentioned purpose, the utility model provides a color-protecting device for low-temperature baking of medicine-food homologous pigment, which comprises a box body and a working chamber arranged in the box body. The special feature is that the working chamber comprises a ceramic liner, an electric heater body wrapped outside the ceramic liner, and an electric insulation layer wrapped outside the electric heater body.

[0005] A constant temperature part is arranged outside the electric insulation layer, and a constant temperature end assembly of the constant temperature part is arranged in the ceramic liner to suppress the constant temperature waiting temperature rise.

[0006] The constant temperature end assembly is closed, isolated, and not connected to the electric heater body and the electric insulation layer.

[0007] Further, the thermostat includes a water pipe and a solenoid valve which are connected to the inside and outside of the chamber of the ceramic liner.

[0008] The thermostat end assembly includes an injection pipe section, an injection four-way pipe, three injection guide pipes, a return four-way pipe and a return pipe section.

[0009] The injection pipe section is connected to the injection cavity of the water pipe.

[0010] The inlet pipe section of the injection four-way pipe is connected to the outlet of the injection pipe section.

[0011] The inlets of the three injection guide pipes are respectively connected to the three injection branch pipe sections of the injection four-way pipe.

[0012] The three return branch pipe sections of the return four-way pipe are respectively connected to the outlets of the three injection guide pipes.

[0013] The outlet pipe section of the return four-way pipe is connected to the inlet of the return pipe section.

[0014] The outlet of the return pipe section is connected to the return cavity of the water pipe.

[0015] The solenoid valve is installed on the inlet pipe section of the injection cavity.

[0016] The injection four-way pipe and the return four-way pipe are respectively arranged at the axial two ends of the ceramic liner, and the three injection guide pipes are arranged along the axial direction of the ceramic liner.

[0017] Further, the front end and the rear end of the three injection guide pipes are respectively fixed on a fixed ring.

[0018] Further, the outlet pipe section of the return cavity is arranged outside the chamber of the ceramic liner, and a pipe thermometer is arranged on the outlet pipe section.

[0019] The beneficial effects of the present application are as follows: through control, the low-temperature liquid (the specific temperature can be determined according to multiple experiments) input into the thermostat and the thermostat end assembly can timely absorb the heat generated by thermal inertia, thereby effectively inhibiting the change of the pigment of the baked product caused by the constant temperature waiting for temperature rise, so that the baked product is in an ideal temperature range, thereby improving the qualified rate and appearance of the finished product.

[0026] After being thus arranged, at least three cold water pipes extending along the axial direction of the ceramic inner container 3 are arranged in the ceramic inner container 3, when the temperature reaches the set temperature and the heating is stopped, at this time, the "constant temperature waiting temperature rise" caused by thermal inertia needs to be inhibited in time, only by opening the electromagnetic valve 9, the low-temperature water (water temperature of water meeting the temperature control requirements prepared in advance according to experiments) in the external water pipe is made to flow through the injection cavity 16, the injection pipe section 10, the injection four-way pipe 11, the three injection guide pipes 13, the return four-way pipe 14, the return pipe section 15 and the return cavity 20, and then return to the water pipe 8 from one end of the ceramic inner container 3 to the other end, and then be discharged, so that heat exchange is realized, and the temperature change of the ceramic inner container 3 is gentle and moderate due to the linear (i.e. relatively stable, without sudden change) stability of the temperature change of the water medium, so that the excessive heat is discharged in time, not only effectively inhibiting the "constant temperature waiting temperature rise" caused by thermal inertia, but also helping to shorten the time of constant temperature, achieving the additional effect of energy saving.
