Description

Technical Field

[0001] The present invention relates to the technical field of whey powder preparation, and particularly relates to a drying device for whey powder preparation. Background Art

[0002] Whey is a natural by-product obtained by dairy enterprises when producing cheese from milk. It is liquid, and whey powder is obtained by directly drying whey. The whey protein in whey powder is extremely low, generally a dozen percent, not exceeding thirty percent, and a drying device is required during the preparation of whey powder.

[0003] The existing drying device for whey powder preparation sprays the whey liquid atomized into the drying chamber during use, and at the same time blows hot air into the drying chamber. The hot air evaporates the moisture in the atomized whey liquid to form whey powder. However, in the above method during the drying process, due to the high flow rates of both the hot air and the atomized whey liquid, there is a problem that the contact time between the hot air and the whey liquid is short, resulting in insufficient drying and affecting the drying effect of the device. In addition, during the drying process of the existing drying device for whey powder preparation, due to the high humidity in the drying chamber, the produced whey powder is likely to adhere to the inner wall of the drying chamber, and it is not easy to clean, which not only affects the output of whey powder but also reduces the functionality of the device. Summary of the Invention

[0004] The purpose of the present invention is to provide a drying device for whey powder preparation to solve the above problems.

[0005] The present invention achieves the above purpose through the following technical solutions:

[0006] A drying device for whey powder preparation includes a drying chamber. A discharge hopper with a conical structure is fixed at the bottom end of the drying chamber. A liquid storage tank is installed on one side wall of the drying chamber. A suction pipe is inserted into the liquid storage tank. A suction pump is provided on the suction pipe. One end of the suction pipe is connected to an atomizing nozzle. A blower is fixed on the side wall of the drying chamber adjacent to the liquid storage tank. A dust-proof net is installed on the suction port of the blower. A duct is provided on the exhaust port of the blower. A heater is installed on the duct. One end of the duct is connected to a shunt pipe. Spiral blades are fixed on the outer side wall of the shunt pipe. A plurality of air guiding nozzles are circumferentially distributed on the outer side wall of the shunt pipe.

[0007] Further, the discharge hopper is welded to the bottom end of the drying chamber, and four support legs are welded to the bottom end of the drying chamber.

[0008] By adopting the above technical solution, the dried whey powder is discharged and collected through the discharge hopper.

[0009] Further, the liquid storage tank is fixed on the drying box by bolts. The pumping pipe penetrates through the liquid storage tank and the top wall of the drying box. The pumping pump is installed on the pumping pipe by bolts, and the atomizing nozzle is installed on the output end of the pumping pipe by threads.

[0010] By adopting the above technical solution, the pumping pump extracts the whey liquid in the liquid storage tank through the pumping pipe, atomizes it through the atomizing nozzle and then sprays it out.

[0011] Further, the blower is fixed on the drying box by bolts. The dust-proof net is fixed on the suction port of the blower by screws. The air duct is connected to the exhaust port of the blower by bolts, and the heater is installed on the air duct by threads.

[0012] By adopting the above technical solution, the blower blows air into the shunt pipe through the air duct. At the same time, the heater heats it to form hot air.

[0013] Further, the shunt pipe is connected to the output end of the air duct by threads. The spiral blade is welded on the outer side wall of the shunt pipe, and the air guiding nozzle is installed on the outer side wall of the shunt pipe by threads.

[0014] By adopting the above technical solution, during the drying process, the atomized whey liquid falls on the spiral blade by gravity and flows along the spiral blade. During the flowing process, the hot air is sprayed out through the air guiding nozzle on the shunt pipe to continuously heat and dry it to form whey powder. The contact time with the hot air can be increased by increasing the flow path of the whey powder, ensuring sufficient drying and improving the drying effect of the device.

[0015] Further, a bearing plate is welded on one side wall of the discharge hopper. A driving motor is installed on the bearing plate by bolts, and a transmission shaft is fixed on the output shaft of the driving motor.

[0016] By adopting the above technical solution, the driving motor can drive the transmission shaft to rotate.

[0017] Further, the transmission shaft is connected to the side wall of the discharge hopper through a bearing. One end of the transmission shaft is connected with a transmission box, and the transmission box is fixed in the discharge hopper through a bracket.

[0018] By adopting the above technical solution, the bracket fixes the transmission box, and the transmission shaft drives the main gear to rotate.

[0019] Further, a main gear and a sub-gear are rotatably installed in the transmission box. The sub-gear meshes with the main gear. One end of the transmission shaft is fixedly connected with the main gear. Both the main gear and the sub-gear are bevel gears.

[0020] By adopting the above technical solution, the main gear drives the driven gear to rotate, and the driven gear drives the rotating shaft to rotate.

[0021] Furthermore, a rotating shaft is led out from the driven gear. The rotating shaft is connected to the transmission case through a bearing. One side of the top end of the rotating shaft is fixed with a connecting rod of an L-shaped structure, and a brush is installed on one side wall of the connecting rod.

[0022] By adopting the above technical solution, the rotating shaft drives the brush to rotate through the connecting rod, so that the brush rotates along the inner wall of the drying box. During the rotation, the whey powder attached to the inner wall of the drying box can be automatically cleaned, ensuring the output of whey powder and improving the functionality of the device.

[0023] Furthermore, a blocking block is arranged at the discharging port of the discharging hopper. The surface of the blocking block is of a conical structure, and two groups of electric push rods are symmetrically installed on both sides of the blocking block.

[0024] By adopting the above technical solution, during the drying process, the electric push rod drives the blocking block to separate from the discharging hopper to enable normal discharging. When it is idle, the electric push rod drives the blocking block to seal the bottom end of the discharging hopper.

[0025] The specific working principle is as follows: Connect the external power supply. During the drying process, the electric push rod drives the blocking block to separate from the discharging hopper to enable normal discharging. Then, the pumping pump extracts the whey liquid in the liquid storage tank through the pumping pipe and sprays it out after atomization by the atomizing nozzle. The blower blows air into the shunt pipe through the air duct, and at the same time, the heater heats it to form hot air. The atomized whey liquid falls on the spiral blade by gravity and flows along the spiral blade. During the flowing process, the hot air is sprayed out through the air guiding nozzle on the shunt pipe to continuously heat and dry it to form whey powder. The contact time with the hot air can be increased by increasing the flowing path of the whey powder to ensure sufficient drying and the drying effect of the device. During the drying process, the driving motor drives the main gear to rotate through the transmission shaft, the main gear drives the rotating shaft to rotate through the driven gear, and the rotating shaft drives the brush to rotate through the connecting rod, so that the brush rotates along the inner wall of the drying box. During the rotation, the whey powder attached to the inner wall of the drying box can be automatically cleaned, ensuring the output of whey powder. The dried whey powder is discharged and collected through the discharging hopper. After drying is completed, the electric push rod drives the blocking block to seal the bottom end of the discharging hopper.

[0026] The beneficial effects of the present invention are as follows:

[0027] 1. By setting a shunt pipe, a spiral blade and a wind guide nozzle, during the drying process, the atomized whey liquid falls on the spiral blade by gravity and flows along the spiral blade. During the flowing process, hot air is ejected from the wind guide nozzle on the shunt pipe to continuously heat and dry it to form whey powder. Furthermore, the contact time with hot air can be increased by increasing the flow path of the whey powder, ensuring sufficient drying and improving the drying effect of the device.

[0028] 2. By setting a driving motor, a transmission shaft, a main gear, a sub-gear, a rotating shaft, a connecting rod and a brush, the driving motor drives the main gear to rotate through the transmission shaft, the main gear drives the rotating shaft to rotate through the sub-gear, and the rotating shaft drives the brush to rotate through the connecting rod. Thus, the brush rotates along the inner wall of the drying box, and during the rotation, the whey powder attached to the inner wall of the drying box can be automatically cleaned, ensuring the output of whey powder and having strong functionality.
