The upper grinding body is a cone with a large diameter on the upper side and a small diameter on the lower side. A conical flow guide cover is arranged on the top of the upper grinding body, and the lower grinding body is fixed to the bottom of the tank body. The lower grinding body is provided with a grinding cavity matching the shape of the upper grinding body, and the upper grinding body is provided with a grinding cavity. The lower grinding body is provided with a feeding cavity, and the feeding cavity and the grinding cavity are separated by the grinding plate. The bottom of the feeding cavity passes through the bottom wall of the tank body and is provided with a feeding port. The bottom of the lower grinding body is provided with a through groove. The top of the rotating shaft passes through the bottom wall of the tank body and the through groove of the lower grinding body and is fixedly connected to the bottom end of the upper grinding body. The outer wall of the rotating shaft and the inner wall of the through groove are sealed and rotatably connected. The output shaft of the reduction motor is transmission-connected to the bottom end of the rotating shaft.
[0006] Optionally, the crushing mechanism includes two crushing rollers arranged inside the tank body and a crushing motor arranged outside the tank body, the two crushing rollers are arranged opposite to each other on the left and right, and the gap between the two crushing rollers corresponds to the feeding port, and the roller shaft of the crushing roller is transmission-connected to the output shaft of the crushing motor.
[0007] Optionally, scraper plates are respectively arranged below the two crushing rollers, and the scraper plates are arranged obliquely, with the higher end of the scraper plates resting on the bottom of the crushing rollers, and the lower end of the scraper plates fixed on the inner wall of the tank body.
[0008] Specifically, the scraper plate is used to scrape off the materials adhering to the surface of the crushing roller.
[0009] Optionally, an inclined material guide plate is arranged below the scraper plate, a higher end of the material guide plate is fixed on the inner wall of the tank body, and a lower end of the material guide plate faces the air guide cover.
[0010] Specifically, the material guide plate facilitates the material to be directed to the guide cover.
[0011] Optionally, supporting legs are provided below the tank body.
[0012] Optionally, a fixed bracket is provided at the bottom of the tank body, one end of the fixed bracket is fixedly connected to the bottom wall of the tank body, and the other end of the fixed bracket is rotatably connected to the rotating shaft.
[0013] Specifically, the fixing bracket can improve the stability of the rotating shaft when it rotates.
[0014] Optionally, an inspection port is also provided on the side wall of the tank body.
[0015] Specifically, the inspection port allows staff to easily inspect and repair equipment inside the tank.
[0016] The utility model also includes other components that enable a grinding device for beverage concentrate raw materials to be used normally, which are all conventional technical means in the field. In addition, the devices or components not limited in the utility model all adopt conventional technical means in the field, such as a grinding motor, a reduction motor and a vibrator.
[0017] The working principle of the utility model is to first put coffee beans into the tank body from the feeding port, start the grinding motor, drive the grinding roller to rotate, and perform preliminary grinding of the coffee beans. Since the coffee beans are rich in water, the ground coffee beans become slurry and fall from the gap between the two grinding rollers, then fall on the guide cover, and flow along the guide cover to the gap between the upper grinding body and the lower grinding body. The coffee bean slurry adhering to the surface of the grinding roller can be scraped off by the scraper plate, fall along the guide plate to the guide cover, and then be diverted to the gap between the upper grinding body and the lower grinding body. The reduction motor is started to drive the rotating shaft to rotate, and then the upper grinding body is driven to rotate. The slurry is further ground, and the ground slurry flows into the discharge cavity through the leakage hole and is finally discharged from the discharge port. In order to facilitate the control of discharge, an equipment control box can be set outside the tank body, and a control switch can be set in the box. The control switch is electrically connected to the vibrator through a wire. The vibrator is started by the control switch, and the material on the grinding plate is quickly dropped by vibration screening. At the same time, due to the small gap between the upper grinding body and the grinding plate, the material adhering to the upper grinding body can be indirectly vibrated off, which can reduce the material sticking to the wall and prevent the leakage hole from being blocked. In addition, after use, the staff can remove the small amount of material remaining in the tank body through the inspection port, which is convenient for later cleaning.
[0018] The beneficial effect of the utility model is that, through the tank body, the crushing mechanism and the grinding mechanism, the material can be crushed first and then ground to improve the fineness of the material. At the same time, the grinding mechanism can reduce the adhesion of the material to the upper grinding body and the grinding plate through the upper grinding body, the vibrator and the lower grinding body, and can also prevent the leakage hole from being blocked, providing convenience for later cleaning; the scraper plate can scrape off the material adhered to the surface of the crushing roller, the guide plate is convenient for guiding the material to the guide cover, and the guide cover is convenient for guiding the material to between the upper grinding body and the lower grinding body, so as to facilitate grinding.
