Disclosure of Invention

The invention aims to provide a tea frying machine, which solves the problem that tea in the prior art is adhered to a high-temperature pot wall after being contacted with the pot wall for a long time.

In order to achieve the aim, the basic scheme of the invention provides a tea leaf frying machine which comprises a support and a spiral frying device, wherein the spiral frying device comprises a motor, a timer, a connecting rod, a position switch for detecting the connecting rod, an air pump, a heating ring, a frying plate with an arc-shaped cross section, a spiral blade for conveying tea leaves and a cylindrical shell, the shell is fixed on the support, two ends of the shell are closed, two ends of the shell are respectively provided with a discharge port and a feed port, the upper part of the shell is internally provided with an air cavity, and the inner wall of the upper part of the shell is provided with a plurality of air injection holes communicated; the electric frying machine comprises a shell, a motor, an air pump, a frying plate, a heating ring, spiral blades, connecting rods and air blocking plates, wherein the motor and the air pump are fixed on a support, the output end of the air pump is communicated with an air cavity, the frying plate is rotatably connected to two ends of the shell, the frying plate is fixedly connected to the output end of the motor, the frying plate is positioned in the heating ring, the heating ring is fixed on the support, the spiral blades are fixed on the frying plate, the connecting rods are fixed on the spiral blades, the connecting rods are parallel to the central line of the shell, the; the position switch is fixed on the inner wall of the shell and positioned on the upper part of the shell, the position switch is electrically connected with the motor and the timer, and the timer is electrically connected with the motor.

The principle of the basic scheme is as follows: the timer is set to be the time required by single heating of the tea leaves, the tea leaves are loaded into the shell from the feed inlet, and the motor and the heating ring are started. The heating ring makes the stir-frying plate in a high-temperature state, and the stir-frying plate starts to rotate under the driving of a motor of the motor. When the frying plate rotates, the helical blade rotates along with the frying plate, and the helical blade scrapes the tea leaves to the inner wall of the upper part of the shell when rotating. At the moment, the connecting rod fixed on the helical blade rotates to the upper part of the shell, and the air blocking plate on the connecting rod blocks the air injection hole. After the position switch on the upper part of the shell detects the connecting rod, an electric signal is sent to the motor and the timer, the motor stops rotating, and the timer starts timing. When the motor stops rotating, the tea leaves positioned on the upper part of the shell fall onto the arc-shaped frying plate and are placed in the concave part of the frying plate to be heated. When the time of the timer reaches the set time, the timer sends an electric signal to the motor to restart the motor, and meanwhile, the limit switch is reset. The frying plate is driven by the motor to continuously rotate to pour the tea leaves to the lower part of the shell, but part of the tea leaves are adhered to the frying plate due to juice evaporated at high temperature, and the juice is continuously heated to be dried by distillation to generate adhesion. The connecting rod continues to rotate under the drive of the helical blade, and the air blocking plate also rotates along with the connecting rod. The air blocking plate exposes the air jet holes when rotating, and the pressure air injected into the air cavity by the air pump is ejected from the air jet holes. The pressure gas can not flow rapidly between the blades of the screw thread blades, turbulent flow is formed between the blades of the screw thread blades, tea leaves on the frying plate are blown away, and the tea leaves are prevented from contacting with the frying plate for a long time to cause serious adhesion.

After being fried for many times, the tea leaves are conveyed to a discharge hole by a helical blade and discharged.

The beneficial effect of this basic scheme lies in: 1. this device is equipped with the timer, can set up single stir-fry time, can reduce the emergence because of the adhesion condition that the hot time overlength arouses. Therefore, the device solves the problem that the tea leaves can be adhered to the pot wall when being contacted with the pot wall with high temperature for a long time in the prior art.

2. The tea leaf heating device enables the frying plate to heat tea leaves at intervals through the matching of the position switch, the timer and the connecting rod. Meanwhile, after the tea leaves are poured into the frying plate, the tea leaves adhered to the frying plate are blown away, so that the adhesion condition is further avoided.

3. The helical blades in the device have the conventional transportation function, and meanwhile, a space with unsmooth air circulation is formed between the blades of the helical blades, so that the condition for blowing and lifting tea leaves from the frying plate by turbulent flow is provided.

The first optimization scheme is as follows: the stir-frying plate is provided with a plurality of through holes. The setting up of through-hole makes indiscriminate flow can blow to the depressed face of frying the system board from frying the system board bottom, consequently can blow off the tealeaves of adhesion on frying the system board better, has further prevented that the condition of tealeaves adhesion from taking place.

And the second optimization scheme is as follows: the cross section of the air blocking plate is in an arc shape matched with the inner wall of the shell. The design reduces the gap between the air blocking plate and the inner wall of the upper part of the shell, so that the air blocking effect is better. Prevent to make the board at the frying to the tealeaves heating, a large amount of pressure gas gets into and blows away tealeaves, influences the effect of frying.

And the optimization scheme is three: the circumferential angle of the air blocking plate is equal to that of the stir-frying plate. The design ensures that the air immediately enters the shell after the frying plate is turned over, and the tea leaves are blown away from the frying plate, thereby further reducing the adhesion condition.

And the optimization scheme is four: the stir-frying plate is made of copper. The heat conducting property of the copper metal is good, and the energy utilization rate is improved.

And the optimization scheme is five: and a collecting box is arranged at the discharge port. The arrangement of the collecting box facilitates the collection of the fried tea.
