Description

Technical Field

[0001] The utility model relates to an energy-saving electric tea fixation machine for tea processing. Background Art

[0002] Most of the existing tea electric fixation machines are drum-type fixation machines or track-type fixation machines. It is difficult to divide the temperature zones inside the drum-type fixation machine. The requirement for tea fixation is that the initial temperature is relatively high to quickly increase the temperature of the tea, and the subsequent temperature is relatively low to make the tea dehydrate and soften evenly. Obviously, the tea fixed by the drum-type fixation machine will reduce the final quality of the tea. Although the track-type fixation machine can set different temperature zones inside to reach the appropriate temperature for tea fixation process, since it often fixes the tea by indirect heating, the fixation time is long and the energy consumption is relatively high. Content of the Utility Model

[0003] The purpose of the utility model is to overcome the above deficiencies of the existing technology, and provide an energy-saving electric tea fixation machine for tea processing with high processing efficiency and quality, and it also has a certain energy-saving effect.

[0004] The technical solution of the utility model is: an energy-saving electric tea fixation machine for tea processing, including a main body, a fixation tank is arranged at the top of the main body. The fixation tank is composed of a plurality of heating tanks arranged in parallel. Each heating tank is provided with multiple heating zones with gradually decreasing temperatures, and the thickness of the heating tank corresponding to each heating zone increases in turn. The end with a thinner thickness of the heating tank is located in the tea input direction, and the end with a thicker thickness of the heating tank is located in the tea output direction;

[0005] Positive and negative connectors are respectively arranged at both ends of each heating tank, and a high-temperature resistant insulating layer is also arranged at the connection of each heating tank.

[0006] Specifically, the high-temperature resistant insulating layer is a mica layer.

[0007] Furthermore, the fixation tank is inclined and arranged at the top of the main body.

[0008] Specifically, the higher end of the fixation tank is located in the tea input direction, and the lower end of the fixation tank is located in the tea output direction.

[0009] Preferably, the included angle between the fixation tank and the horizontal plane is ≤ 45°.

[0010] Furthermore, an arc-shaped groove is also arranged at the bottom of the heating tank, and a temperature measuring instrument is fixed in the arc-shaped groove.

[0011] Optionally, the heating tank is connected by a plurality of arc-shaped plates with gradually increasing thicknesses.

[0012] Preferably, the heating tank is connected by three arc-shaped plates with gradually increasing thicknesses.

[0013] Specifically, the arc-shaped plates are connected end to end in sequence and welded into one body.

[0014] Optionally, the heating groove is formed by bending a whole plate body.

[0015] The beneficial effects of the present utility model are as follows:

[0016] When using the present utility model to carry out tea fixation, the entire fixation process only takes about one minute. Due to the fast fixation speed, energy can be saved, and the quality of the tea fixed by the present utility model is significantly improved compared with that processed by the existing tea fixator; moreover, the input power supply of the present utility model is a low-voltage and high-current power supply of ≤36V, and it also has the advantages of safety and reliability.

[0017] Among them, the heating groove of the present utility model is composed of arc-shaped metal plates with gradually increasing thickness. Since the resistance of metal plates with different thicknesses is different, different temperature regions will be generated when passing the same current, which can meet various temperature requirements at each time period during the processing of tea or other foods and is easy to control the temperature.

[0018] In addition, according to actual needs, metal plates with different thicknesses can be arbitrarily combined to obtain more heating grooves with different temperature ranges. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Figure 3 is Figure 1 an enlarged view of part A in DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The technical solutions of the present utility model will be further specifically described below through embodiments and in conjunction with the drawings.

[0023] Combined with Figures 1-3 shown in the figure, an energy-saving electrothermal tea fixator for tea processing includes a main body. A fixation groove is provided at the top of the main body. The fixation groove is composed of a plurality of heating grooves 1 arranged in parallel. Each heating groove 1 is provided with a plurality of heating zones 2 with gradually decreasing temperatures. The thickness of the heating groove 1 corresponding to each heating zone 2 gradually increases. The thinner end of the heating groove 1 is located in the tea input direction, and the thicker end of the heating groove 1 is located in the tea output direction;

[0024] Both ends of each heating groove 1 are respectively provided with a positive electrode and a negative electrode connector, and a high-temperature resistant insulating layer 3 is also provided at the connection of each heating groove 1.

[0025] In another embodiment, it further includes an access power supply, and the voltage of the access power supply is ≤ 36V.

[0026] Specifically, the high-temperature resistant insulating layer 3 is a mica layer.

[0027] It should be noted that the mica layer is only a preferred embodiment of the high-temperature resistant insulating layer 3, and other materials with high-temperature resistant insulating properties such as fiberglass layers and epoxy resin layers can also be used as the high-temperature resistant insulating layer 3.

[0028] In another embodiment, the withering trough is inclined and arranged at the top of the main body so that the tea leaves can slide down along the slope of the withering trough under the action of the shaking of the main body.

[0029] Specifically, the higher end of the withering trough is located in the tea leaf input direction, and the lower end of the withering trough is located in the tea leaf output direction.

[0030] Preferably, the included angle between the withering trough and the horizontal plane is ≤ 45°, so as to prevent the tea leaves from sliding out of the withering trough too fast and not having enough heating and withering time.

[0031] In another embodiment, as Figure 3 shown, an arc-shaped groove 5 is further provided at the bottom of the heating trough, and a thermometer is fixed in the arc-shaped groove 5 for real-time monitoring of the temperature of the heating trough.

[0032] In another embodiment, in combination with Figures 1-3 shown, the heating trough 1 is connected by a plurality of arc-shaped plates 4 with gradually increasing thicknesses in sequence. The heating trough 1 with this structure has a lower manufacturing cost, and the resistance values of the respective heating zones 2 are significantly different, and the temperature differences when the respective heating zones 2 generate heat are also relatively obvious.

[0033] Preferably, the heating trough 1 is connected by three arc-shaped plates 4 with gradually increasing thicknesses in sequence.

[0034] Specifically, the respective arc-shaped plates 4 are connected end to end in sequence and welded into one body.

[0035] In another embodiment, the heating trough 1 is formed by bending a whole plate body, and the thickness of the plate body gradually increases from front to back. The heating trough 1 with this structure has a higher manufacturing cost, mainly due to the higher cost of the plate body itself, but it has the advantages of a smooth surface without solder joints, a more stable and reliable structure, and a long service life.

[0036] The working principle and beneficial effects of the above structure are as follows: The tea leaves are input from the higher end of the fixing trough. At this time, the power supply of the fixing trough is turned on. Since the high-temperature insulating layer 3 is arranged between the heating troughs 1, the heating speeds of the heating troughs 1 tend to be consistent. Also, since the thicknesses of the heating zones 2 of the heating trough 1 increase in sequence and the resistances decrease in sequence, one end of the whole heating trough 1 in the tea leaf input direction has a higher temperature, while the other end has a lower temperature, meeting the temperature requirements for tea leaf fixing; under the action of the shaking of the main body, the tea leaves falling into the fixing trough slide down along the slope of the fixing trough, are heated by the heating zones 2 of each section, are quickly fixed and output. The entire fixing process only takes about one minute. Since the fixing speed is fast, energy can be saved, and the quality of the fixed tea leaves is significantly improved compared with that of the tea leaves processed by the existing fixing machines; moreover, the input power supply of the above structure is a low-voltage and high-current power supply of ≤36V, and it also has the advantages of safety and reliability;

[0037] Among them, the heating trough of the present utility model is composed of arc-shaped metal plates with increasing thicknesses in sequence. Since the resistances of the metal plates with different thicknesses are different, different temperature regions will be generated when the same current passes through, which can meet various temperature requirements at each time period during the processing of tea leaves or other foods and is easy to control the temperature;

[0038] In addition, according to actual requirements, the metal plates with different thicknesses can be arbitrarily combined, and more heating troughs with different temperature ranges can be obtained.
