Description

Technical Field

[0001] This utility model relates to the field of powdered coffee processing technology, and in particular to a low-temperature grinding and anti-oxidation processing device for powdered coffee. Background Technology

[0002] When processing powdered coffee, grinding is required to break down coffee beans into powder. Existing grinding equipment has a relatively simple structure and can only perform simple grinding of coffee beans. When using traditional grinding equipment, the friction between the grinding block and the coffee beans generates local high temperatures (usually as high as 40-60°C), which leads to the loss of volatile aromatic substances. At the same time, the mechanical impact accelerates the contact between coffee powder and oxygen, causing lipid oxidation and Maillard reaction to occur prematurely, which significantly reduces the freshness and flavor profile of the product and affects the processing quality of powdered coffee. To address these issues, we propose a low-temperature grinding and anti-oxidation processing device for powdered coffee. Utility Model Content

[0023] Working Principle: During use, the operation of the device is controlled via the control panel 110. Coffee beans are injected into the feed tank 210 through the feeding pipe 211. The geared motor 230 drives the drive shaft 231 to rotate, which in turn drives the stirring rack 240 and the screw conveyor 250 to rotate. The stirring rack 240 stirs the coffee beans, ensuring that they are fully in contact with the cold air, achieving all-round cooling of the coffee beans. The screw conveyor 250, in conjunction with the feeding pipe 220, evenly conveys the coffee beans into the grinding mechanism, achieving high-precision feeding of the coffee beans. In operation, after the coffee beans enter the installation cylinder 310, the rotation of the spiral conveyor rod 250 drives the installation shaft 320 to rotate, which in turn drives the conical grinding block 340 to rotate. The outer ring grinding block 330 and the conical grinding block 340 work together to grind the coffee beans. The ground coffee powder is collected by the collection box 410 and the storage hopper 420. When discharge is required, the discharge control valve 440 opens, and the coffee powder is discharged from the device through the installation pipe 430 and the discharge pipe 450. During the process, the blower 520 is started, and the blower 520... The cold air generated by the semiconductor cooler 530 is extracted through the connecting pipe 521 and delivered to the connecting pipe 610 and the connecting pipe B640 via the gas supply pipe A540 and the tee connector 550. The cold air enters the gas collecting ring A620 through the connecting pipe 610, and finally fills the feed tank 210 with cold air through multiple nozzles A630, which can cool the coffee beans during the feeding stage. At the same time, the cold air enters the gas collecting ring B650 through the gas supply pipe B640, and finally injects the cold air into the mounting cylinder 310 through multiple nozzles B660, which can cool the coffee beans during the grinding process. The coffee beans are cooled and cooled in all directions. Next, the air inlet pipe 740 is connected to an external inert gas storage tank, the control valve 741 is opened, and the circulating air pump 720 is started. The circulating air pump 720 injects inert gas into the collection box 410 through the filling pipe 730. When the collection box 410 is full of inert gas, the return air pipe 750 is connected to the circulating air pump 720. The circulating air pump 720 can circulate and transport the inert gas, which can expel the air inside the collection mechanism and prevent the coffee powder from oxidizing.
