Description

Technical Field

[0001] The utility model relates to the technical field of pre-prepared food processing, in particular to a spice grinder. Background Art

[0002] Various spices are often used in the preparation of dishes. For example, star anise, angelica dahurica and cinnamon are used in the preparation of braised beef. The quality and amount of these spices are one of the key factors to ensure the quality and consistency of food flavor. Powdered spices are easy to measure and can also release all the spices in a short time, shortening the preparation time of dishes.

[0003] Existing grinders often directly put spices into the grinder for grinding during use, and then directly discharge the materials. However, spices are fruits, leaves or bark of plants, etc., which will be mixed with dust and various impurities. For example, star anise is mixed with fruit stems, which reduces the quality of the spices after grinding. In addition, during the grinding process, the spices collide repeatedly with each other, causing their temperature to rise. Since the spices contain volatile oils, the temperature rise will accelerate the attenuation and volatilization of the effective ingredients of the spices, thereby reducing the quality and flavor of the spices. Utility Model Content

[0004] The utility model provides a spice grinder, which can solve the above technical problems.

[0005] The utility model is achieved through the following technical solutions:

[0006] A spice grinder includes a feeding mechanism, a grinding chamber, a cooling mechanism and a feeding mechanism.

[0007] The feeding mechanism includes a cylinder and a first screw conveying assembly built into the cylinder. The shell of the first screw conveying assembly is provided with a plurality of through holes. A space is formed between the cylinder and the shell of the first screw conveying assembly to receive impurities falling from the through holes.

[0008] The crushing chamber is communicated with the discharge port of the first spiral conveying assembly;

[0009] The cooling mechanism includes a cooling chamber, a cooling pipe and a liquid supply assembly. The cooling chamber is connected to the discharge port of the crushing chamber. The cooling pipe is wound around the feeding mechanism, the cooling chamber and the discharge mechanism. The liquid supply assembly is connected to the cooling pipe.

[0010] The unloading mechanism comprises a second spiral conveying assembly, and the feed port of the second spiral conveying assembly is communicated with the cooling chamber.

[0011] Furthermore, an adjustment cylinder is coaxially arranged with the shell, and the adjustment cylinder is movably connected to the outer wall of the shell. The adjustment cylinder is provided with an adjustment hole corresponding to the through hole and having the same size as the through hole.

[0012] Furthermore, a discharge port is provided on the cylinder body, and a guide plate inclined toward the discharge port is provided inside the cylinder body.

[0013] Furthermore, it also includes a hopper, which is connected to the end of the first spiral conveying assembly away from the crushing chamber.

[0015] Furthermore, a plurality of heat sinks are connected to the outer surface of the cooling pipe wound around the cooling chamber.

[0016] Furthermore, a cooling pipe is wound in the cooling chamber.

[0017] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0018] A spice grinder comprises a feeding mechanism, a grinding chamber, a cooling mechanism and a discharge mechanism. Spices are put into a first spiral conveying assembly, and the first spiral conveying assembly conveys the spices to the grinding chamber. During the movement of the spices in the first spiral conveying assembly, impurities fall into the cylinder through the through holes on the shell of the first spiral conveying assembly to achieve impurity separation. The liquid supply assembly conveys cooling liquid into the cooling pipe, and the cooling liquid flows to the cooling pipe wound on the feeding mechanism, exchanges heat with the feeding mechanism, and pre-cools the spices to be crushed in the feeding mechanism. Then, the cooling liquid flows to the cooling pipe wound on the cooling chamber, exchanges heat with the cooling chamber, and cools down the crushed spices. Subsequently, the cooling liquid flows to the cooling pipe wound on the discharge mechanism, and exchanges heat with the discharge mechanism. In contrast, the spices are further cooled during the feeding process, and finally, the coolant flows back to the liquid supply component to cool the spices before crushing, thereby reducing the initial temperature of the spices. The temperature of the cooled spices after grinding is lower than the temperature of the uncooled spices after grinding. The heated spices are not fed directly, but are cooled in the cooling chamber before feeding, which can quickly reduce the temperature of the spices and reduce the attenuation and volatilization of their effective components. The spices are further cooled by arranging a cooling pipe wound around the second spiral conveying component to further reduce the attenuation and volatilization of their effective components. The quality of the spices is improved after the impurities are separated, and the cooled spices reduce the attenuation and volatilization of the effective components of the spices caused by heating, thereby maintaining the quality and flavor of the spices.

The feeding mechanism includes a cylinder 20 and a first spiral conveying component 21 built into the cylinder 20. The shell of the first spiral conveying component 21 is provided with a plurality of through holes. A space for receiving impurities falling from the through holes is formed between the cylinder 20 and the shell of the first spiral conveying component 21. One end of the cylinder 20 is connected to the end connected to the support column. The other end of 20 is connected to the grinding chamber 10. The cylinder 20 can be tilted upward or horizontally. The cylinder 20 is provided with heat dissipation holes for dissipating the heat of the motor of the first spiral conveying assembly 21. For example, it also includes a hopper 22. The hopper 22 is connected to the end of the first spiral conveying assembly 21 away from the grinding chamber 10. The hopper 22 is connected to the grinding chamber 10 through a feeding mechanism. Compared with the hopper 22 being directly connected to the grinding chamber 10, it can reduce the powder flying out of the feed port due to the centrifugal force of the grinding chamber 10 during the grinding process, thereby causing certain dust pollution and volatilization loss of spices.

[0031] The cooling mechanism includes a cooling chamber 30, a cooling pipe 31 and a liquid supply assembly 33. The cooling chamber 30 is connected to the discharge port of the crushing chamber 10. The cooling pipe 31 is wound around the feeding mechanism, the cooling chamber 30 and the discharge mechanism. The liquid supply assembly 33 is connected to the cooling pipe 31. For example, the liquid supply assembly 33 includes a water pump and a water tank. The liquid inlet of the water pump is connected to the water tank, and the liquid outlet of the water pump is connected to the cooling pipe 31. The coolant can be water, which has low cost, large heat capacity, and good heat absorption and thermal conductivity. In order to increase the performance of the water-cooled liquid, antibacterial and anti-fouling agents can be added. Foam additives and anti-corrosion additives, etc. Preferably, the cooling tube 31 is made of copper, has good thermal conductivity, and has a good heat dissipation effect. For example, the outer surface of the cooling tube 31 wound around the cooling chamber 30 is connected to a plurality of heat sinks 32. The cooling chamber 30 is where heat gathers. The provision of a plurality of heat sinks can increase the heat dissipation area to accelerate heat dissipation. The material of the heat sink 32 can be selected from copper-aluminum composite material, which combines the advantages of copper and aluminum, and utilizes the rapid heat absorption of copper and the rapid heat release of aluminum to achieve better heat dissipation effect.

[0032] The unloading mechanism includes a second spiral conveying assembly 23 , and a feed port of the second spiral conveying assembly 23 is communicated with the cooling chamber 30 .

[0033] A spice grinder includes a feeding mechanism, a grinding chamber 10, a cooling mechanism and a discharge mechanism. Spices are fed into a first spiral conveying assembly 21, which conveys the spices to the grinding chamber 10. During the movement of the spices in the first spiral conveying assembly 21, impurities fall into the cylinder 20 through the through holes on the shell of the first spiral conveying assembly 21, thereby achieving impurity separation. The liquid supply assembly 33 conveys cooling liquid into the cooling pipe 31, and the cooling liquid flows to the cooling pipe 31 wound on the feeding mechanism, exchanges heat with the feeding mechanism, and pre-cools the spices to be crushed in the feeding mechanism. Then, the cooling liquid flows to the cooling pipe 31 wound on the cooling chamber 30, exchanges heat with the cooling chamber 30, and cools the crushed spices. Subsequently, the cooling liquid flows to the cooling pipe 31 wound on the discharge mechanism. , and exchanges heat with the feeding mechanism, further cooling the spices during the feeding process, and finally, the cooling liquid returns to the liquid supply component 33, cooling the spices before crushing, thereby reducing the initial temperature of the spices. The temperature of the cooled spices after grinding is lower than the temperature of the uncooled spices after grinding. The heated spices are not fed directly, but are cooled by the cooling chamber 30 before feeding, which can quickly reduce the temperature of the spices and reduce the attenuation and volatilization of their effective components. By arranging the cooling pipe 31 wound around the second spiral conveying component 23, the spices are further cooled, and the attenuation and volatilization of their effective components are further reduced. The quality of the spices is improved after the impurities are separated, and the cooled spices reduce the attenuation and volatilization of the effective components of the spices caused by the temperature increase, thereby maintaining the quality and flavor of the spices.

[0034] In another embodiment, an adjusting cylinder 211 is coaxially provided with the shell, and the adjusting cylinder 211 is movably connected to the outer wall of the shell.

For example, a guide rail is circumferentially provided on the outer surface of the shell, and a slide groove corresponding to the guide rail is provided on the inner surface of the adjusting cylinder 211. A limiting pressure rod 212 for limiting the displacement of the adjusting cylinder 211 is provided on the outer wall of the shell. The limiting pressure rod 212 is movably connected to the shell, for example, the limiting pressure rod 212 is fixed to the shell by a nut. When the impurities to be screened are small, , unscrew the nut to release the restriction of the adjusting cylinder 211, rotate the adjusting cylinder 211 to make the adjusting hole and the through hole misaligned, and the adjusting hole and the through hole partially overlap, and the impurities allowed to pass through also become smaller. When the adjusting cylinder 211 is rotated to the preset position, tighten the nut to restore the restriction of the adjusting cylinder 211. When the impurities to be screened are large, rotate the adjusting cylinder 211 to adjust the size of the overlapping area of ​​the through hole and the adjusting hole. The maximum impurities allowed to pass through are equal to the size of the through hole. This setting is suitable for screening spices with different particle sizes, increasing the versatility and flexibility of the equipment.

[0035] In another embodiment, the cylinder 20 is provided with a discharge port 201 , and a guide plate 20 is provided in the cylinder 20 and is inclined toward the discharge port 201 , so as to guide the impurities falling into the cylinder 20 to be discharged to the discharge port 201 .

[0036] In another embodiment, the feeding mechanism also includes a negative pressure pump and a dust collecting box. The air inlet of the negative pressure pump is connected to the discharge port 201 of the cylinder 20, and the air outlet of the negative pressure pump is connected to the dust collecting box. The negative pressure pump forms a negative pressure, so that the impurities that fall into the upper barrel through the screen cylinder enter the dust collecting box, thereby improving the efficiency of impurity discharge.

[0037] In another embodiment, a cooling pipe 31 is wound around the cooling chamber 30.
