Description

Technical Field

[0001] This utility model relates to the field of feed additive production technology, specifically a freeze dryer for feed additive production. Background Technology

[0002] Feed additives refer to small or trace amounts of substances added during feed production, processing, and use. They are used in very small quantities but have significant effects. Feed additives contain a certain amount of moisture, which needs to be removed using a freeze dryer before storage to prevent mold and spoilage.

[0003] Existing freeze dryers use the principle of sublimation for drying. Since feed additives contain moisture, when they are piled up inside the freeze dryer for drying, a large amount of feed additives tend to stick together and form large clumps of material. This makes it very easy for the feed additives to have different drying effects inside and outside the freeze dryer during the drying process. Utility Model Content

[0022] This utility model provides a technical solution: such as Figures 1 to 5 As shown in this embodiment, a freeze dryer for feed additive production includes a freeze dryer body 1, a support leg 2 fixedly connected to the bottom end of the freeze dryer body 1, a door 3 rotatably connected to the outer wall of the freeze dryer body 1, a vacuum pump 4 fixedly connected to the top end of the freeze dryer body 1, a flipping mechanism 5 provided inside the freeze dryer body 1, a protrusion 54 fixedly connected to the inner wall of the freeze dryer body 1, a groove 55 opened on the outer wall of the protrusion 54, and a gear 510 rotatably connected to the inner wall of the protrusion 54.

[0023] The freeze dryer body 1 is fixedly connected to the outer wall of a first motor 51, and the outer wall of the first motor 51 is fixedly connected to an output shaft 52. A gear 510 is fixedly connected to the outer wall of the output shaft 52, and a rubber plate 53 is fixedly connected to the outer wall of one end of the output shaft 52 located inside the freeze dryer body 1.

[0024] The rubber plate 53 can be rotated to flip the material above the placement plate 56, thereby preventing the material from accumulating on the placement plate 56.

[0025] The inner wall of the slide groove 55 is slidably connected to a connecting rod 512. One end of the connecting rod 512 is fixedly connected to a placement plate 56, and the other end of the connecting rod 512 is fixedly connected to a rack 511. The rack 511 meshes with a gear 510, and the outer wall of the gear 510 is missing some teeth.

[0026] Through gear 510, rack 511 meshes with gear 510, and the rotation of gear 510 can drive rack 511 to move.

[0027] Among them, a moving rod 59 is fixedly connected to the bottom end of the placement plate 56, a positioning rod 57 is fixedly connected to the bottom inside of the freeze dryer body 1, a spring 58 is fixedly connected to the bottom inside of the positioning rod 57, and the top end of the spring 58 is fixedly connected to the bottom end of the moving rod 59.

[0028] Spring 58 deforms when stretched by an external force and recovers itself when not subjected to external force, thus vibrating the placement plate 56.

[0029] The freeze dryer body 1 is equipped with a crushing mechanism 6 at its top, and a crushing box 61 is fixedly connected through the top of the freeze dryer body 1.

[0030] The crushing mechanism 6 can crush large pieces of material that have already agglomerated.

[0031] The inner wall of the crushing box 61 is rotatably connected to a first crushing roller 62 and a second crushing roller 63, and the outer wall of the crushing box 61 is fixedly connected to a shell 64, and the outer wall of the shell 64 is fixedly connected to a second motor 65.

[0032] The first crushing roller 62 and the second crushing roller 63 work together to crush large pieces of material, thereby preventing uneven drying between the inside and outside of the material.

[0033] The outer wall of the first crushing roller 62 is fixedly connected to a drive shaft 66, and the end of the drive shaft 66 away from the first crushing roller 62 is fixedly connected to a second motor 65. The outer wall of the second crushing roller 63 is fixedly connected to a driven shaft 67, and the outer wall of the drive shaft 66 is drivenly connected to a drive belt 68, and the end of the drive belt 68 away from the drive shaft 66 is drivenly connected to the outer wall of the driven shaft 67.

[0034] The rotation of the drive shaft 66 via the drive belt 68 can drive the driven shaft 67 to rotate.

[0035] This utility model provides a freeze dryer for feed additive production. The specific working principle is as follows: During use, when large clumps of material appear inside the material, the crushing chamber 61 is opened, and the material is poured into the crushing chamber 61. The second motor 65 is turned on, driving the drive shaft 66 to rotate. The rotation of the drive shaft 66 drives the driven shaft 67 to rotate via the transmission belt 68. The rotation of the drive shaft 66 drives the first crushing roller 62 to rotate, and the rotation of the driven shaft 67 drives the second crushing roller 63 to rotate. The first crushing roller 62 and the second crushing roller 63 work together to crush the clumps of material, preventing uneven drying between the inside and outside of the material during the drying process. When drying the material, it is placed above the placement plate 56, and the freeze dryer and the first motor 51 are turned on. The freeze dryer dries the material, and the first motor... 51 drives the output shaft 52 to rotate, which in turn drives the rubber plate 53 to rotate. The rotation of the rubber plate 53 flips the material, keeping the material above the placement plate 56 in motion. The rotation of the output shaft 52 drives the gear 510 to rotate, which in turn drives the rack 511 to move upward. The movement of the rack 511, through the connecting rod 512, drives the placement plate 56 to move upward. The movement of the placement plate 56 drives the moving rod 59 to move inside the positioning rod 57, and the moving rod 59 drives the spring 58 to stretch. When the gear 510 disengages from the rack 511, the placement plate 56 moves downward under its own weight, squeezing the spring 58. As the gear 510 continues to rotate, the placement plate 56 continuously vibrates the material above it, preventing material accumulation and further improving the drying effect of the material.
