Description

A kind of tea baking machine

Technical field

The utility model relates to a kind of tea machinery, is specifically related to a kind of tea baking machine.

Background technology

The kind of existing tea baking machine has a lot, but has following defective mostly; The one, the energy-conserving and environment-protective aspect is done inadequately, is embodied in that the hot type amount is big, energy consumption big (power attenuation is big).The 2nd, the temperature of box house is unbalanced, and the product drying degree that causes curing is uneven, and quality is variant; Reason is to cure the incipient stage because the humidity of product is higher, so need quick hydrofuge, then needs temperature more stable during the time to curing lower semisection; But the steam vent of existing equipment and venthole all are one, and are fixed sizes; Cause most of user in use will open a period of time hydrofuge to the door of curer, cause sizable energy loss; And inconvenient operation, time length often occurs curing, cure shortcomings such as inhomogeneous.Above defective causes cures machinery to cure benefit not high, has had a strong impact on tea grower's income, has also influenced the development of tea industry.

The utility model content

The purpose of the utility model is to overcome the deficiency that the above-mentioned background technology exists; A kind of improvement of tea baking machine is provided; Make these facility be equipped with even, the measured characteristics of baked product matter of temperature in the casing, and baking efficiency is high, energy-conserving and environment-protective and simple in structure, rationally distributed.

The technical scheme that the utility model is taked is: a kind of tea baking machine, comprise a casing, and the electric cabinet that casing is provided with chamber door and controls each electrical equipment is characterized in that being provided with in the cabinets cavity rotating putting and puts the screen frame (unit) that tealeaves is used; The hot blast chamber that is shaped on blowing mouth that the top of said casing is provided with air inlet, heat conductor endothermic tube, the blower fan by driven by motor, the heating element that is communicated with in regular turn through air inlet duct and is arranged on casing one side; The dehumidifier mouth that is used to extract wet wind that the top of casing also is provided with air outlet, the heat conductor heat release pipe that is communicated with in regular turn through the exhaust passage and is arranged on the cabinets cavity top.

The multilayer screen tray of horizontal arrangement is installed on the said screen frame (unit); This screen frame (unit) is rotatably positioned in casing through the central shaft that its center vertically is provided with, and by being arranged on bottom half and driving by the reduction box of driven by motor.

Said hot blast chamber is made up of the air intake plate of vertical layout and the inner surface of casing one side, and heating element communicates with this hot blast chamber through air inlet duct, is evenly equipped with one group of blowing mouth on the air intake plate; These blowing mouths are aimed at aforementioned multilayer screen tray one by one.

The air outlet of described connection exhaust passage is separately positioned on the casing outer tip end with the air inlet that is communicated with air inlet duct.

Said heating element is 3, and 3 heating elements are divided into two groups, and two groups of heating elements are arranged on the top of said casing.

The bottom of said casing is provided with discharge outlet.

Said casing lower end is equipped with return pulley.

The operation principle of the utility model is: each electric component of this machine starts after the energising; The cold air that under fan action, is sucked by air inlet is introduced into heat conductor endothermic tube (tube bank of U-shaped aluminum air channel) and absorbs heat, also gets into discharges heat in the heat conductor heat release pipe via the dehumidifier hole by the hot moisture of discharging in the casing simultaneously; According to heat-conduction principle, the heat of the hot moisture in the heat conductor heat release pipe just can pass to the cold wind (cold wind is carried out preheating) in the tube bank of U-shaped aluminum air channel; Again the moisture of low temperature after the heat exchange is discharged via moisture exhausting port; Be arranged on the heating element on cabinets cavity top simultaneously, make it to become hot blast to heating through the air after the preheating of heat conductor endothermic tube again, hot blast gets into the hot blast chamber and through the blowing mouth on the air intake plate tealeaves on each screen tray is heated then; Screen frame (unit) then rotates under the drive of motor, rotates thereby drive the tealeaves that is placed on the screen tray, makes the tealeaves thermally equivalent, thereby reaches the purpose of curing.

The beneficial effect of the utility model is: because the heat conductor intensity of heat exchange of this machine configuration is high; Function with heat recovery (adopts the design of shell-and-tube; Help under mean temperature difference, working, simple in structure, and increased heat transfer area); Make the cold wind temperature that gets into curer improve 40 ℃-50 ℃, improved the efficient of curing greatly; The speed that heats is fast, and it is long to cure time of process outage insulation, has saved a large amount of energy consumptions, really plays energy-conserving action; And the heating tube in the heat conductor has adopted simple load and unload Pipe bundle structure, and needing to change only needs when perhaps cleaning will restrain to extract out to get final product, and is rational in infrastructure and reliable; The resistance that has guaranteed the fluid in the heat exchange is less, has reduced the power consumption of heat conductor, has further practiced thrift the energy, has improved efficient, and is simultaneously simple in structure, rationally distributed, also helps environmental protection.
