Description

Technical Field

[0001] The present application relates to the technical field of tea processing, and in particular to a mulberry leaf tea roasting machine. Background Art

[0002] A tea roasting machine is needed in the processing of tea. The roasting machine is a mechanical equipment used to roast newly picked tea leaves. Its main function is to evaporate the moisture in the tea leaves by heating and stirring, so as to achieve the processing steps of dehydration, withering, rolling, etc., so as to make the tea leaves have better quality and taste without destroying the natural form of the tea leaves and maintaining the original aroma of the tea leaves. Different tea leaves require different temperatures during processing. The roasting temperature of Pu'er tea should be controlled between 180-200 degrees Celsius, and the roasting time should be between 5-10 minutes. The specific time can be determined according to the degree of withering and drying of the tea leaves. After the roasting is completed, cooling and heat dissipation are usually required. The existing heat dissipation means usually use fans for exhaust, and the cooling speed is slow, and the cooling cannot be carried out synchronously, resulting in low cooling efficiency of the roasting equipment, thereby affecting the quality and production progress of the tea leaves. Utility Model Content

[0003] The purpose of the present application is to provide a mulberry leaf tea roasting machine, which solves the problem that the existing heat dissipation means proposed in the background technology usually uses fans for exhaust, the cooling speed is slow, and the cooling cannot be carried out synchronously, resulting in low cooling efficiency of the roasting equipment, thereby affecting the quality of the tea and the production progress.

[0004] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a mulberry leaf tea roasting machine, comprising a base, an outer cylinder, an inner cylinder, a connecting frame and an outer tooth groove, the outer cylinder is fixedly installed on the top surface of the base, a water adding groove is provided on the inner side of the inner cylinder, the water adding groove is connected to the outside through two water inlets and outlets provided at the right end of the inner cylinder, a plurality of heat sinks are evenly fixedly inserted on the outer surface of the inner cylinder, the bottom of the heat sink is located on the inner side of the water adding groove, two vertical plates are fixedly installed on the top of the base on the left side of the inner cylinder, two exhaust fans are fixedly installed on the surface of the vertical plate facing the inner cylinder, and a plurality of heating resistance wires are fixedly installed below the inner surface of the inner cylinder.

[0005] In this technical solution, tea leaves are poured into the inner cylinder along the feeding port, and then the motor is powered on and started, driving the transmission rod and the inner cylinder to rotate. Four gears are respectively provided at the edges of both ends of the inner cylinder, and mesh in the outer tooth grooves, so as to maintain stability during the rotation. The heating control switch controls the heating resistor to be powered on and generate heat, and heats the inside of the inner cylinder until the required temperature is adjusted. The heat can be dissipated evenly through the water inlet and outlet and the water adding tank. When heat dissipation is required after the tea frying is finished, one of the two water inlets and outlets is connected to an external water source, and water is pumped into the water adding tank, and then discharged from the water inlet and outlet on the other side, and the cycle continues. The water intake and pumping will absorb and discharge the heat, and the heat absorption treatment can be evenly carried out at each position, which improves the heat dissipation effect. At the same time, the heat sink, vertical plates, exhaust fan and vents can assist the heat discharge. The bottom of the heat sink is located in the water tank, so it can absorb the heat in the water and dissipate it to the outside of the inner cylinder. After the exhaust fan is started, it will continue to blow to the right, and exhaust air towards the heat sink in the gap between the outer cylinder and the inner cylinder, thereby accelerating the heat discharge. The vents are connected to the inside of the inner cylinder, and the exhaust fan can also synchronously exhaust air for the tea leaves to assist in heat dissipation, further improving the efficiency of heat discharge.

The output end of the transmission shaft of the motor passes through the connecting frame and is fixedly connected to the transmission rod in the center of the left end of the inner cylinder.

[0007] As an optional solution of the technical solution of the present application, a feeding port is opened in the center of the right end of the inner cylinder, a heating control switch is fixedly installed on the left end surface of the inner cylinder, and a ventilation port is opened on the left end surface of the inner cylinder on the side of the heating control switch.

[0008] As an optional solution of the technical solution of the present application, a discharge port is provided below the central surface of the outer cylinder, and a cylinder door is hingedly connected to the central surface of the inner cylinder.

[0009] As an optional solution of the technical solution of the present application, the inner surface edges on both sides of the outer cylinder are provided with outer tooth grooves surrounding the outer cylinder.

[0010] As an optional solution of the technical solution of the present application, the left and right end edges of the inner cylinder are fixedly connected with four fixed blocks equidistantly in a circular array, and the side walls of the fixed blocks are rotatably connected with gears, which mesh with the external tooth grooves.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The present application can facilitate uniform heat dissipation through the water inlet and outlet and the water adding tank. When heat dissipation is needed after tea frying, one of the two water inlets and outlets is connected to an external water source, water is pumped into the water adding tank, and then discharged from the water inlet and outlet on the other side. Continuous water intake and pumping will absorb and discharge the heat, and each position can be evenly treated for heat absorption, thereby improving the heat dissipation effect.

[0013] 2. The present application can assist in the discharge of heat through heat sinks, vertical plates, exhaust fans and vents. The bottom of the heat sink is located in the water tank, so it can absorb the heat in the water and dissipate it outside the inner cylinder. After the exhaust fan is started, it will continue to blow to the right, and exhaust air toward the heat sink in the gap between the outer cylinder and the inner cylinder, thereby accelerating the discharge of heat. The vents are connected to the inside of the inner cylinder, and the exhaust fan can also synchronously exhaust air for the tea leaves to assist in heat dissipation, further improving the efficiency of heat discharge.

The outer cylinder 2 is fixedly mounted on the top surface of the base 1, and two vertical plates 13 are fixedly mounted on the top of the base 1 on the left side of the inner cylinder 3. Two exhaust fans 14 are fixedly mounted on the side surface of the vertical plate 13 facing the inner cylinder 3. The exhaust fans 14 can blow air into the gap between the vent 15 and the inner cylinder 3 and the outer cylinder 2, so as to assist in heat dissipation.

[0022] like Figure 1 As shown, the upper and lower ends of the connecting frame 11 are fixedly connected to the upper and lower sides of the left end of the outer cylinder 2 respectively, and a motor 12 is fixedly installed in the center of the left side wall of the connecting frame 11. The output end of the transmission shaft of the motor 12 passes through the connecting frame 11 and is fixedly connected to the transmission rod 121 in the center of the left end of the inner cylinder 3.

[0023] like Figure 2 As shown, a discharge port 10 is provided below the central surface of the outer cylinder 2, and a cylinder door 9 is hingedly connected to the central surface of the inner cylinder 3. When the tea leaves need to be discharged, the inner cylinder 3 is rotated so that the cylinder door 9 reaches the discharge port 10 and then opened.

[0024] like Figure 1 and Figure 3 As shown, a heating control switch 501 is fixedly installed on the left end surface of the inner tube 3, and a vent 15 is provided on the left end surface of the inner tube 3 on one side of the heating control switch 501. The heating control switch 501 controls the temperature of the heating resistance wire 5 by controlling the magnitude of the current. This technical feature is relatively mature, so it will not be described in detail.

[0025] like Figure 3 As shown, a water adding tank 4 is provided on the inner side of the inner cylinder 3, and the water adding tank 4 is connected to the outside through two water inlets and outlets 401 provided on the right end of the inner cylinder 3. A plurality of heat sinks 6 are evenly fixedly inserted on the outer surface of the inner cylinder 3, and the bottom of the heat sink 6 is located on the inner side of the water adding tank 4. A plurality of heating resistors 5 are fixedly installed below the inner surface of the inner cylinder 3, and the heat sink 6 can assist in absorbing the heat of the water in the water adding tank 4, thereby assisting in heat dissipation.

[0026] like Figure 2 and Figure 4 As shown, the inner surface edges of the left and right sides of the outer cylinder 2 are provided with outer tooth grooves 201 that surround the cylinder, and a feeding port 301 is provided in the center of the right end of the inner cylinder 3. The left and right end edges of the inner cylinder 3 are fixedly connected with four fixed blocks 7 at equal intervals in a circular array, and the side walls of the fixed blocks 7 are rotatably connected with gears 8 that mesh with the outer tooth grooves 201. The four gears 8 can support the inner cylinder 3 so that it will not deviate.

[0027] In actual use, tea leaves are poured into the inner cylinder 3 along the feeding port 301, and then the motor 12 is powered on and started, driving the transmission rod 121 and the inner cylinder 3 to rotate. Four gears 8 are respectively provided at the edges of both ends of the inner cylinder 3, and mesh in the outer tooth grooves 201, so as to maintain stability during the rotation process. The heating control switch 501 controls the heating resistor to be powered on and generate heat, and heats the inside of the inner cylinder 3 until the required temperature is adjusted. When heat dissipation is required after the tea frying is completed, one of the two water inlets and outlets 401 is connected to an external water source, and water is pumped into the water adding tank 4, and then discharged from the water inlet and outlet 401 on the other side, and the cycle continues. When water is taken in and pumped out, the heat will be absorbed and discharged, and each position can be evenly treated with heat absorption, thereby improving the heat dissipation effect. The bottom of the heat sink 6 is located in the water tank 4, so it can absorb the heat in the water and dissipate it to the outside of the inner cylinder 3. After the exhaust fan 14 is started, it will continue to blow to the right, and exhaust air towards the heat sink 6 in the gap between the outer cylinder 2 and the inner cylinder 3, thereby accelerating the discharge of heat, and the vent 15 is connected to the inside of the inner cylinder 3. The exhaust fan 14 can also synchronously exhaust air for the tea leaves to assist in heat dissipation, thereby further improving the efficiency of heat discharge. After the heat dissipation is completed, the cylinder door 9 can be opened to export the tea leaves.
