An insulating layer is filled between the refrigerant pipe 8 and the outer layer of the box body 1.

[0023] Specifically, the tea seeds that have been pressed for oil are frozen, and taking advantage of the brittle and hard characteristics of the frozen tea seeds, the frozen tea seeds are put into the box 1 through the feeding port 6, so that the crushing rollers 2 are squeezed against each other, and the tea seeds are broken into particles and fall into the relative grinding rollers 3. After being squeezed and rubbed by the grinding rollers 3, the tea seeds are crushed into powder and fall onto the vibrating screen 5 at the bottom. After being sieved by the vibrating screen 5, those that meet the particle requirements fall into the collecting hopper 4 and flow out of the box 1 through the fine material outlet 7. The refrigerant pipes 8 in the cavities of the inner and outer layers of the box 1 keep the temperature inside the box 1 at a low level at all times, which not only avoids the heat rise generated during the crushing and grinding process, but also keeps the tea seeds in a frozen state during the crushing and grinding process, making grinding easier. The tea seed powder has a low viscosity and is not easy to solidify and stick.

[0024] In one embodiment of the present application, preferably, a first collecting plate 9 is provided between the crushing roller pair 2 and the grinding roller 3 , and the first collecting plate 9 is fixedly connected to the box body 1 , so as to allow all the crushed tea seeds to fall into the grinding roller 3 .

[0025] In one embodiment of the present application, preferably, a second material collecting tray 10 is provided between the grinding roller 3 and the vibrating screen 5 , and the second material collecting tray 10 is fixedly connected to the box body 1 , so that the ground tea seed powder can fall onto the vibrating screen 5 .

[0026] In one embodiment of the present application, preferably, a plurality of springs 11 are fixedly connected between both sides of the vibration screen 5 and the box body 1 , and a vibration motor 12 is fixedly connected to one side of the vibration screen 5 for vibrating the vibration screen 5 .

[0027] In one embodiment of the present application, preferably, a coarse material outlet 13 is opened on the side wall of the collecting hopper 4 at the bottom end of the vibrating screen 5, and the coarse material outlet 13 is fixedly connected to a feed pipe 14, and the other end of the feed pipe 14 is fixedly connected to a screw conveyor 15, and the top of the screw conveyor 15 is fixedly connected to a discharge pipe 16, and the other end of the discharge pipe 16 is fixedly connected to the box body 1, and the outlet of the discharge pipe 16 is located above the first collecting plate 9, which is used to transport the coarse particles screened out from the vibrating screen 5 to the top of the grinding roller 3 for re-grinding.

[0028] In one embodiment of the present application, preferably, the screw conveyor 15 includes an outer cylinder 151, a screw shaft 152 and a screw 153, the screw 153 is fixedly connected to the screw shaft 152, the screw shaft 152 is rotatably connected to the outer cylinder 151, a conveying motor 154 is fixedly connected to the outer cylinder, and a driving shaft of the conveying motor 154 is fixedly connected to the screw shaft 152, for conveying coarse particles to the top discharge pipe 16.

[0029] In one embodiment of the present application, preferably, the crushing roller pair 2 and the grinding roller 3 are fixedly connected to the central shaft 17, the central shaft 17 is rotatably connected to the housing 1, and the central shaft 17 is fixedly connected to the gear 18, and the gears 18 corresponding to each pair of grinding rollers 3 and the crushing roller pair 2 are meshed, and three motors 19 are fixedly connected to the housing 1, and the driving shafts of the three motors 19 are respectively fixedly connected to each pair of grinding rollers 3 and one of the central shafts 17 of the crushing roller pair 2, so as to drive the crushing roller pair 2 and the grinding roller 3 to rotate.

[0030] In summary, the tea seed fine grinding equipment in the above embodiment of the utility model, specifically, freezes the tea seeds that have been squeezed for oil, and uses the characteristics of the frozen tea seeds being brittle and hard to put the frozen tea seeds into the box body 1 through the feeding port 6, starts the motor 19 to squeeze the grinding rollers 2 against each other, and the tea seeds are broken into particles and fall into the relatively squeezed grinding rollers 3, and are squeezed and rubbed into powder by the grinding rollers 3, and fall onto the vibrating screen 5 at the bottom, and are sieved by the vibrating screen 5. Those that meet the particle requirements fall into the collecting hopper 4 and flow out of the box body 1 through the fine material outlet 7, and those that do not meet the particle requirements enter the conveying pipe 14 from the coarse material outlet 13 at the bottom under the action of the vibrating screen 5, and The tea seeds are transported upward to the discharge pipe 16 through the screw conveyor 15, enter the box 1 from the discharge pipe 16, fall onto the first gathering plate 9, and enter the grinding roller 3 again for grinding until the grinding is completed. The refrigerant pipe 8 in the cavity of the inner and outer layers of the box 1 keeps the temperature in the box 1 low at all times, which not only avoids the heat rise generated during the crushing and grinding process, but also keeps the tea seeds in a frozen state during the crushing and grinding process, making grinding easier. The tea seed powder has a low viscosity and is not easy to solidify and stick. The device utilizes the reduced viscosity of the tea seed powder in the frozen state to facilitate grinding and screening, which can improve production efficiency. It is not easy to stick to the equipment and is also convenient for cleaning and maintenance of the equipment.
