Abstract
Description
Technical Field
[0001] The utility model belongs to the field of experimental animal feed processing, in particular to a maturing device for preventing experimental animal feed from leaking and coking. Background Art
[0002] Laboratory animal feed is the main source of nutrients for animals. The quality of feed has a direct impact on animal quality and animal experimental results. The nutrients in feed mainly include crude protein, crude fat, carbohydrates, minerals, vitamins and water. The granulation process of laboratory animal feed mainly includes raw material receiving and processing - raw material crushing - primary mixing - secondary crushing and mixing - conditioning and granulation - drying - cooling - packaging.
[0003] The feed conditioning section is to mature the raw materials and heat and pressure treat them with high-temperature steam. After the feed raw materials are matured, their digestibility and nutritional value can be improved, and the burden on the digestive system of experimental animals can be reduced. The feed that has been matured can reduce the feed expansion rate, making it easier to swallow and be digested and absorbed by animals, reducing feed waste. In addition, the feed that has been matured is not easy to cause mold due to factors such as moisture and saturation, reducing the risk of feed pollution and environmental pollution.
[0004] The tempering agitator in the prior art is mainly composed of a cylinder, a stirring shaft, a seat bearing, a reducer, a motor, a steam addition port, a molasses and grease addition buckle, a safety magnet, a lifter, etc. The stirring shaft is mainly composed of paddles in the same direction, and there is a small gap between the stirring shaft and the inner cylinder wall. Due to the distance between the stirring shaft and the inner cylinder wall, the cooked raw materials are adhered and cannot be moved. Secondly, the cylinder wall cannot rotate or shake, and cannot help the adhesion to fall off. There is only one steam port, and the paddles cannot increase more contact areas at the same angle and direction.

The stirring assembly 3 includes a transmission rod 31, the surface of the transmission rod 31 is fixedly connected to a connecting rod 32, the surfaces of the connecting rod 32 are respectively fixedly connected to a first spiral blade 33 and a second spiral blade 34, and the output shaft of the motor 4 is transmission-connected to the transmission rod 31 through a coupling.
[0024] like Figure 1-4As shown, an inner cylinder 2 is added to the inner part of the outer cylinder 1, and the inner cylinder 2 is movably arranged. When the output shaft of the motor 4 drives the transmission rod 31 to rotate, the transmission rod 31 drives the connecting rod 32 to move, and the connecting rod 32 drives the first spiral blade 33 and the second spiral blade 34 to rotate, so as to stir the internal raw materials. At the same time, since the second spiral blade 34 contacts the inner wall of the inner cylinder 2, the second spiral blade 34 can drive the inner cylinder 2 to rotate while rotating, so that the inner cylinder 2 drives the retained raw materials inside to move. The first spiral blade 33 and the second spiral blade 34 are double-layer spirals, so that during the stirring and rotating process, the material can be driven to move forward at a uniform speed in the direction of the spiral movement, thereby increasing the contact area between the raw material and the high-temperature steam, effectively reducing the situation where the feed raw materials are adhered to the inner wall after maturation, and improving the sensory quality of the feed.
[0025] Example 2
[0026] Reference Figure 1 and 4 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment.
[0027] In this embodiment, the top of the inner tube 2 is connected to a feed hopper 21, the bottom of the inner tube 2 is connected to a discharge pipe 22, the right side of the inner tube 2 is connected to a steam pipe 5, and the surfaces of the feed hopper 21, the discharge pipe 22 and the steam pipe 5 are all connected to valves.
[0028] Bases 14 are fixedly connected to both sides of the bottom of the outer cylinder 1 , a bracket 41 is fixedly connected to the bottom of the motor 4 , and one end of the bracket 41 away from the motor 4 is fixedly connected to the outer cylinder 1 .
[0029] like Figure 1 and 4 As shown, the feed hopper 21 facilitates the transfer of raw materials to the interior of the inner tube 2 for later processing operations, while the discharge pipe 22 facilitates the discharge of processed raw materials, and the steam pipe 5 facilitates the transfer of steam to the interior of the inner tube 2 for processing the raw materials. The feed hopper 21, the discharge pipe 22 and the steam pipe 5 are conveniently opened or closed by the valve, the outer tube 1 can be stably supported by the base 14, and the bracket 41 can stably support the motor 4, thereby ensuring the stability of the outer tube 1 and the motor 4.
[0030] Example 3
[0031] Reference Figure 1 , 2 and 4, which are the third embodiment of the present utility model, and this embodiment is based on the first two embodiments.
[0032] In this embodiment, the top of the feed hopper 21 is movably connected with a sealing cover, the top of the outer cylinder 1 is provided with a second through slot 12 , the feed hopper 21 passes through the inner cavity of the second through slot 12 , and is slidably connected with the inner cavity of the second through slot 12 .
[0033] A first through groove 11 is formed at the bottom of the outer cylinder 1 , and the discharge pipe 22 passes through the inner cavity of the first through groove 11 and is slidably connected with the inner cavity of the first through groove 11 .
[0034] A third through slot 13 is formed on the right side of the outer tube 1 , and the steam pipe 5 passes through the inner cavity of the third through slot 13 and is slidably connected with the inner cavity of the third through slot 13 .
[0035] like Figure 1 , 2 As shown in FIG. 4 , when the inner cylinder 2 moves, the inner cylinder 2 will drive the feed hopper 21, the first through groove 11 and the third through groove 13 to move. When the feed hopper 21 moves, it will move along the inner cavity trajectory of the second through groove 12. When the discharge pipe 22 moves, it will move along the inner cavity trajectory of the first through groove 11. When the steam pipe 5 moves, it will move along the inner cavity trajectory of the third through groove 13. Therefore, the second through groove 12, the first through groove 11 and the third through groove 13 can limit the steam pipe 5, the feed hopper 21 and the discharge pipe 22 to ensure their movement trajectories and prevent misalignment.
[0036] When in use, firstly, by opening the valve on the surface of the feed hopper 21, the raw materials can be transmitted to the inner cavity of the inner tube 2 through the feed hopper 21, and by opening the valve on the surface of the steam pipe 5, the steam is injected into the inner cavity of the inner tube 2 through the steam pipe 5, and then the motor 4 is turned on, and the output shaft of the motor 4 drives the transmission rod 31 to rotate, and the transmission rod 31 rotates while driving the connecting rod 32 to move, and the connecting rod 32 drives the first spiral blade 33 and the second spiral blade 34 to rotate, so that the internal raw materials are stirred by the first spiral blade 33 and the second spiral blade 34, and at the same time, because the second spiral blade 34 contacts the inner wall of the inner tube 2, and the inner There is a movable arrangement between the cylinder 2 and the outer cylinder 1, so that the force generated by the rotation of the second spiral blade 34 can drive the inner cylinder 2 to rotate, so that the inner cylinder 2 drives the retained raw materials inside to move to prevent the raw materials from being left behind. At the same time, the first spiral blade 33 and the second spiral blade 34 are set as a double-layer spiral, so that during the stirring and rotating process, the material can be driven to move forward at a uniform speed in the direction of the spiral movement, thereby increasing the contact area between the raw material and the high-temperature steam, which not only effectively reduces the situation where the feed raw materials stick to the inner wall after maturation, but also improves the sensory quality of the feed. After stirring, the raw materials will be discharged through the discharge pipe 22 by opening the valve on the surface of the discharge pipe 22.
