[0002] Coffee beans are the fruit of the plant used to make coffee. A coffee bean consists of two oval seeds facing each other. The side where they meet is flat and called a flat bean. However, some coffee beans consist of a single round seed, called a round bean, but their taste is no different.

[0003] In existing technologies, coffee bean preservation tends to use airtight containers. However, when the relative humidity of the air is high, it is difficult to avoid the coffee beans becoming damp in the airtight container, which affects the quality of the coffee beans. Utility Model Content

[0004] The purpose of this invention is to provide a drying device for coffee preservation. The coffee beans are dried and preserved by means of a drying box. However, when coffee beans are piled up on the only support plate of the drying box, the density of the coffee beans will increase, the gaps inside the coffee beans will be small, the flow of hot air will be reduced, and the coffee beans inside will not come into contact with the flowing drying gas, which is not conducive to the overall drying of the coffee beans.

[0005] To achieve the above objectives, a drying device for coffee preservation is provided, comprising a housing, wherein three bearing chambers are slidably connected inside the housing, and a perforated bearing plate is fixedly installed at the bottom of each of the three bearing chambers.

[0028] The inner wall of the housing 18 is provided with a sliding groove 15, and a slider 16 is slidably connected to the sliding groove 15. The sliders 16 are fixedly connected to both sides of the bearing chamber 11. One end of the bearing chamber 11 passes through the outer housing 18 and is fixedly connected to a second handle 6. When taking out or putting in coffee beans, pull the second handle 6 outward, and the bearing chamber 11 will be slid open by the cooperation of the sliding groove 15 and the slider 16.

[0029] The housing 20 is fixedly installed on the upper end of the housing 18. An air outlet 3 is provided at the connection between the housing 20 and the housing 18. A filter screen 1 is provided on the top of the housing 20. The filter screen 1 can prevent large and obvious pollutants from falling into the air outlet 3 and entering the housing 20.

[0030] The first activated carbon filter plate 2 is movably arranged inside the shell 20. The first activated carbon filter plate 2 can effectively filter pollutants, and a bag of desiccant is placed on the first activated carbon filter plate 2 to increase the drying and dehumidification effect. One end of the first activated carbon filter plate 2 passes through the outer shell 20 and is fixedly connected to the first handle 4. Pulling out the first handle 4 is used to replace the first activated carbon filter plate 2 and the desiccant.

[0031] An air inlet 10 is provided at the upper end of the fan room 22, and a second activated carbon filter plate 23 is provided at the upper end of the air inlet 10. The second activated carbon filter plate 23 can filter pollutants, purify the incoming air, and reduce the contact between pollutants and coffee beans.

A third handle 17 is fixedly connected to one end of the drawer 13. Pulling out the third handle 17 is used to clean the coffee bean residue.

[0033] The second activated carbon filter plate 23 has fixing plates 28 spaced apart on both sides. Fixing clamps 24 are slidably connected to the sides of the fixing plates 28, and fixing bolts 26 are threadedly connected to the middle of the fixing plates 28. After the fixing plates 28 are adjusted to a suitable height and match the height of the second activated carbon filter plate 23, their four corners are fixed.

[0034] The fixing plate 28 has three protrusions 27 on its side and the fixing clip 24 has three grooves 29 on its side. The three protrusions 27 and the three grooves 29 cooperate with each other. The height of the three protrusions 27 and the three grooves 29 can be adjusted up and down according to the height of the fixed content. After the adjustment is appropriate, the three protrusions 27 and the three grooves 29 will mesh with each other and be fixed.

[0035] Working principle: When in use, the first handle 4 is used to slide open the bearing chamber 11 with the cooperation of the slide groove 15 and the slider 16. Coffee beans are placed in the bearing chamber 11. After closing the bearing chamber 11, the hot air blower 21 is turned on. The airflow is filtered through the second activated carbon filter plate 23 and enters the blower chamber 22 through the air inlet 10. The hot air blower 21 heats the filtered gas into hot airflow, which is then transported to the air inlet chamber 14 through the air delivery pipe 19. The hot airflow flows from bottom to top through the porous bearing plate 9 and the porous vertical partition plate 8, expanding the space and improving the flow of hot airflow, increasing the contact area between the coffee beans and the hot airflow, until it exits from the air outlet 3. When the coffee beans have accumulated for a certain period of time, the electric push rod 5 is activated to drive the electric rake 7 to make a straight back-and-forth motion, which disperses the coffee beans that have accumulated deep inside and brings them into contact with the hot airflow, reducing the problem of uneven drying of coffee beans.

[0036] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
