Description

Technical Field

[0001] The invention relates to the technical field of food processing, in particular to cocoa bean drying equipment. Background Art

[0002] Vibrating fluidized bed is a highly efficient drying equipment, which is used to dry granular food and grains.

[0003] See also Figure 1 Its working principle is as follows: the processed material first enters the interior of the fluidized bed body 1 through the screw conveyor 2 driven by the motor 3, the fluidized bed body 1 is fixedly installed through the base 4, and then the processed material enters the fluidizing sheet 5, and the hot air blown upward through the hot air outlet 6 can blow up the processed material, so that the processed material forms a fluidized state, and the hot air from bottom to top then passes through the vibration tube 7 into the collection tube 8, and then is discharged through the confluence pipe 9, and the dried processed material directly enters the material collection box 10 through the shaking of the vibration motor on the fluidized bed body 1.

[0004] It can be seen from the above text that when the existing fluidized bed body 1 is drying materials, the hot air is discharged directly from bottom to top through the manifold 9. During this process, the processed materials are constantly vibrated and rubbed, and the debris on the processed materials will enter the interior of the vibration tube 7, the collection tube 8 and the manifold 9 together with the hot air, causing dust accumulation inside most pipes. After working for a long time, the internal wind resistance of the vibration tube 7, the collection tube 8 and the manifold 9 increases, affecting the air outlet efficiency. In addition, the aperture of the existing fluidizing sheet 5 is not suitable for the processing of various processed materials, because the volume of the processed materials is not fixed, and too small an aperture will lead to low air outlet efficiency and poor drying effect. Therefore, how to solve the problems of air outlet efficiency and the practicality of the aperture of the fluidizing sheet 5 is also the research direction of the present invention. Summary of the invention

A water bath 11 is fixedly installed on the back of the fluidized bed 1, a damping tube 12 is fixedly installed on the top of the water bath 11, and one end of the damping tube 12 away from the water bath 11 is located inside the fluidized bed 1, and a heat exchange plate 13 is fixedly installed inside the water bath 11. The inner cavity of the water bath 11 is divided into two parts. The upper part of the water bath 11 is provided with a heat exchange box 14, and the lower part of the water bath 11 is provided with a water bath bin 15. The interior of the water bath bin 15 is filled with clean water 16. The water level of the clean water 16 should be higher than the bottom end of the heat exchange plate 13 by more than 2 cm. By setting the water level of the clean water 16 to be higher than the bottom end of the heat exchange plate 13 by more than 2 cm, it can be ensured that the material residue in the hot air can be immersed in the clean water 1 6 is separated from the inside, the heat exchange plate 13 is made of stainless steel, and the length of the heat exchange plate 13 is the same as the length of the water bath 11, the two sides of the heat exchange plate 13 are glued to the inner wall of the water bath 11, and the bottom of the heat exchange plate 13 is provided with a water level sensor assembly. The heat exchange plate 13 is made of stainless steel, so that the heat exchange plate 13 will not produce obvious rust after long-term use, and the setting of gluing the two sides of the heat exchange plate 13 to the inner wall of the water bath 11 can ensure the sealing effect of the two sides of the heat exchange plate 13 and the inner wall of the water bath 11, so as to ensure that the hot air can pass through the clean water 16 when filling the water bath chamber 15 for water bathing, and the back of the water bath chamber 11 is fixedly installed with an air outlet pipe 17 inside the water bath chamber 15, and the air outlet pipe A collecting pipe 8 is fixedly installed at one end of 17 away from the water bath 11, a hot air recovery pipe 18 is fixedly installed at the back of the water bath 11, and an air inlet of a dustproof device is symmetrically arranged on the right side of the heat exchange box 14 and the hot air recovery pipe 18. Through the setting of the air inlet of the dustproof device, fresh cold air can enter the interior of the heat exchange box 14, and the heat inside the heat exchange box 14 can be brought out for secondary utilization. A water inlet pipe 19 is fixedly installed on the side of the water bath bin 15, and a water outlet pipe 20 is fixedly installed at one end of the side of the water bath bin 15 away from the water inlet pipe 19. A crank 21 is fixedly installed on the right side of the fluidized bed 1, a hot air hole 22 is opened on the surface of the fluidizing sheet 5, and a moving sheet 23 is movably installed directly below the fluidizing sheet 5. The shape of the hot air hole 22 is elliptical, and the hot air hole The shape of 22 is an elliptical setting, which can make the ellipses on the fluidizing sheet 5 and the moving sheet 23 cooperate with each other, and the size change of the aperture is controlled by the left and right movement of the two ellipses. The bottom of the moving sheet 23 is provided with a limit block 24 fixedly welded to the inner cavity of the fluidized bed 1, and a rack 25 is fixedly welded to the bottom of the right side of the moving sheet 23. A fixed-point gear 26 is meshed below the rack 25. The fixed-point gear 26 is fixedly welded to the inner wall of the fluidized bed 1 through a rotating shaft. The fixed-point gear 26 is fixedly welded to the inner wall of the fluidized bed 1 through a rotating shaft. The setting that the fixed-point gear 26 is fixedly welded to the inner wall of the fluidized bed 1 through a rotating shaft can ensure that the fixed-point gear 26 can rotate while ensuring fixation relative to the fluidized bed 1, thereby promoting the left and right movement of the moving sheet 23, and realizing the size change of the aperture of the moving sheet 23 and the fluidizing sheet 5.The lower end of the fixed point gear 26 is meshed with a threaded rod 27, which passes through the fluidized bed 1 and extends to the right side of the fluidized bed 1 where a crank 21 is fixedly installed.

[0024] Working principle: when the device is working, after drying the processed materials, the hot air first enters the water bath chamber 15 through the shock absorbing tube 12. Under the influence of pressure, the hot air will enter the right side of the heat exchange plate 13 through the clean water 16. In this process, the material particles in the hot air are immersed in the clean water 16 to complete the water bath, and the hot air without impurities transfers the heat to the clean water 16, and the clean water 16 transfers the heat to the heat exchange plate 13. The heat exchange plate 13 continues to dissipate the heat to the heat exchange box 14. The hot air recovery pipe 18 and the induced draft fan are used to recover the hot air on the side of the heat exchange box 14. In addition, when using materials of different volumes, you only need to turn the crank 21. At this time, the crank 21 drives the threaded rod 27 to rotate, and the threaded rod 27 drives the fixed point gear 26 at the upper end to rotate, thereby driving the left and right movement of the moving plate 23. The aperture size can be adjusted by the mutual cooperation of the moving plate 23 and the ellipse on the fluidizing plate 5.
