[0028] The stirring assembly 7 comprises a stirring motor 71 and a stirring shaft 73, the stirring motor 71 is installed above the outer box body 1, the upper end of the stirring shaft 73 is sleeved on the top wall of the outer box body 1 through a shaft seat, and the lower end is arranged in the inner cooling box 4, the output end of the stirring motor 71 is fixedly sleeved with a main gear 72, the upper end of the stirring shaft 73 is fixedly sleeved with a driven gear 74, and the main gear 72 and the driven gear 74 are meshed with each other, and the lower end of the stirring shaft 73 is uniformly connected with a plurality of stirring rods, the stirring rods can be uniformly stirred in the inner cooling box by starting the stirring motor 71 to drive the stirring shaft to rotate, the material is further dispersed and the heat exchange is enhanced, so that the feather powder in the inner cooling box is rapidly cooled and cooled, and the uniformity and speed of the feather powder cooling are improved.

[0029] A through hole 44 is formed in the center of the top of the inner cooling box 4, the stirring shaft 73 is movably inserted through the through hole 44, so that a certain gap is left between the stirring shaft 73 and the inner cooling box 4, and the vibration force generated when the inner cooling box 4 vibrates cannot be directly transmitted to the stirring shaft.

[0030] The stirring shaft 73 and the stirring rod are hollow structures, and the refrigerating mechanism 8 comprises a circulating refrigerating device 81 installed on the outer box body 1, and the inlet and outlet of the circulating refrigerating device 81 are respectively connected with the water inlet / outlet pipes 82, and the two water inlet / outlet pipes 82 are respectively connected with the hollow interlayer 42 of the side wall of the inner cooling box 4 and the end of the stirring shaft 73. Specifically, the upper and lower ends of the stirring shaft 73 are respectively sleeved with rotary joints 83, one side of the water inlet / outlet pipe is connected with the upper end of the hollow stirring shaft 73 through the rotary joint, and one side of the water inlet / outlet pipe is communicated with the hollow interlayer 42 of the side wall of the inner cooling box 4. The hollow interlayer 42 of the inner cooling box 4 and the stirring shaft 73 are further connected through the water cooling pipe 84. The water cooling pipe 84 is arranged in a cross shape at the bottom of the inner cooling box, the center of the water cooling pipe 84 is connected with the lower end of the stirring shaft 73 through the rotary joint below, and the outer end of the water cooling pipe 84 is connected with the hollow interlayer of the inner cooling box 4. A circulating refrigerating path is formed between the circulating refrigerating device 81, the water inlet / outlet pipes 82, the stirring shaft 73, the hollow interlayer 42 of the inner cooling box 4 and the water cooling pipe 84, so that the cooling water can flow in the hollow interlayer 42 of the inner cooling box 4 and the hollow stirring shaft 73 through the water cooling pipe 84 and the water inlet / outlet pipes 82, and the feather powder in the inner cooling box 4 is cooled and cooled.

[0031] The water cooling pipe 84 close to the side wall of the inner cooling box 4 is arranged as a flexible pipe to adapt to the deformation caused by the vibration of the inner cooling box 4, and does not affect the normal rotation of the stirring shaft, preventing the water cooling pipe 84 from being damaged due to rigid connection.

[0032] The lifting mechanism 10 is used to drive the bottom frame 9 to move up and down between the sieve plate 43 and the bottom plate 3. When the collecting frame 92 moves to the topmost position, the collecting frame 92 is close to the sieve plate 43, and the sieve holes on the sieve plate 43 can be blocked by the collecting frame 92 to prevent the feather powder in the inner cooling box 4 from leaking out. When the collecting frame 92 moves away from the sieve plate, the sieve holes are opened, and at this time, the inner cooling box 4 continues to vibrate to vibrate and screen the feather powder in the box through the sieve plate. The dispersed feather powder falls into the collecting frame after screening for subsequent removal. The caked feather powder cannot pass through the sieve holes, thereby realizing automatic screening of the caked feather powder.

[0033] The lifting mechanism 10 comprises a driving motor 101 installed on one side of the vertical column of the support 2. The output end of the driving motor 101 is fixedly sleeved with a vertical screw rod 102. The screw rod 102 is threadedly sleeved with a nut 103. The nut 103 is fixedly connected with the supporting plate 91. The other side of the support 2 is vertically fixed with a sliding rod 104. The sliding rod 104 is slidably sleeved with a sliding sleeve 105. The sliding sleeve 105 is fixedly connected with the supporting plate 91. Through the operation of the driving motor 101, the screw rod 102 can be driven to rotate. Under the cooperation of the screw rod 102 and the nut 103, and under the synchronous limiting and guiding action of the sliding rod 104 and the sliding sleeve 105, the bottom frame 9 can be stably driven to move up and down to approach or move away from the sieve plate.

[0034] The sieve plate 43 is hinged to the bottom of the inner cooling box 4 and locked by the pin 12. The sieve plate 43 can be opened from the bottom of the inner cooling box 4 to clean up any remaining small amount of clumps of feather powder.

[0035] In practical use, the rapid cooling device for steam-exploded feather powder of this utility model first controls the bottom frame 9 to move upward through the lifting mechanism 10 until the collection frame 92 is close to the lower part of the sieve plate 43, blocking the sieve holes. Then, the steam-exploded feather powder enters the inner cooling box 4 from the feed inlet 41. The vibration motor 6 is started, and the inner cooling box 4 vibrates. The vibration makes the feather powder evenly dispersed in the inner cooling box 4. At the same time, the stirring motor 71 drives the stirring shaft 73 to rotate, and the feather powder is evenly stirred. The combination of vibration and stirring functions further prevents the feather powder from clumping.

[0036] Meanwhile, the refrigeration mechanism 8 continues to work, and the circulating refrigeration equipment 81 delivers coolant to the hollow jacket 42 and stirring shaft 73 of the inner cooling box 4 through the inlet / outlet water pipes 82, so that the coolant circulates and cools down in the hollow jacket 42 and stirring shaft 73, thus cooling the feather powder. After cooling, the temperature of the feather powder decreases, avoiding protein denaturation and amino acid oxidation caused by high temperature. When the feather powder has cooled down, the lifting mechanism 10 controls the bottom frame 9 to move downward, and the vibration motor 6 is started again to drive the inner cooling box 4 to vibrate and screen the feather powder in the box. A large amount of dispersed feather powder falls into the collection frame after screening to be removed later. A small amount of clumped feather powder cannot pass through the sieve holes and remains in the inner cooling box 4, realizing the automatic removal of clumped feather powder. Example

[0037] Based on Embodiment 1, in order to further improve the support stability of the inner cooling box 4 inside the outer casing 1, such as... Figure 3 As shown, a rope 11 is installed on the top of the inner cooling box 4. The upper end of the rope 11 is pulled and fixed to the top of the outer box 1, and the rope plays an auxiliary fixing role. By pulling the rope 11, the inner cooling box can be lifted, which can share the weight of the inner cooling box with the spring 5. This solves the problem that the inner cooling box 4 is easily fatigued and failed due to the rapid fatigue of the spring due to the weight of the inner cooling box 4 itself, which is connected by the spring alone.

[0038] The above description is only a preferred embodiment of the present utility model and does not limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
