Description

Technical Field

[0001] The utility model relates to the field of preparation equipment for producing pig feed, in particular to a preparation device for producing pig feed. Background Art

[0002] In the pellet feed production process, conditioning is a comprehensive pretreatment of powdered materials before pelleting. It is the process of fully mixing and absorbing the powder to be pelletized and the appropriate amount of steam, fat, molasses, etc. in the conditioner. Among the many factors that affect feed quality, once the feed formula and production process are determined, controlling the conditioning system is the most critical factor in improving pellet quality and producing optimal production conditions for heating or adding water to the feed. The pellet feed conditioning system must include the ability to accurately control heat and water addition, regardless of the method of addition. Heat is a necessary condition for the gelatinization of starch components in the feed. Gelatinization makes the pellets have better adhesion, formability and durability. In addition, heat can kill pathogens and corrupt microbial tissues in the feed, and promote the drying of pellet feed in the cooler. Water is used for starch gelatinization and makes the feed lubricating through the die.

[0003] During the pretreatment of the granulated powder using steam for tempering, the feeding speed of the tempered powder and the steam conveying speed should be considered comprehensively so that the granulated powder entering the tempering equipment can move forward with an ideal material layer thickness, and in the process of moving forward, the granulated powder can fully contact the steam, fully utilize the heat carried by the steam, and also use the liquefied water condensed after the steam is liquefied to evenly adhere to the granulated powder. However, during the process of the granulated powder in the tempering equipment being transported at a normal speed, if the amount of granulated powder received by the tempering equipment is too large, the material layer thickness of the granulated powder moving forward in the tempering equipment will increase, so that the granulated powder cannot achieve the preset tempering effect after completing one online tempering in the tempering equipment, thereby affecting the subsequent process. Therefore, uniformly and stably conveying an appropriate amount of the powder to be granulated into the tempering equipment for tempering treatment is one of the conditions for the powder to be granulated to fully complete the tempering treatment, and it is also a condition to ensure that the subsequent process can proceed stably. It is worthy of consideration and improvement, so as to improve product quality. Summary of the invention

When the parameter fed back by the gravity sensor 3 reaches the preset range, the material to be quenched and tempered is stopped from being transported to the storage tank 1. When this step is completed, the preparation work before the material to be quenched and tempered is completed.

[0024] Then, open the stop valve 4, the first drive motor 20, the second drive motor 26 on the first star-shaped air lock 6 and the second drive motor 26 on the second star-shaped air lock 12, and reasonably adjust the output power of the first drive motor 20, the output power of the second drive motor 26 on the first star-shaped air lock 6 and the output power of the second drive motor 26 on the second star-shaped air lock 12; at this time, the material to be tempered stored in the storage tank 1 is conveyed to the buffer tube 9 through the feed pipe 7 after being decelerated and conveyed by the first star-shaped air lock 6, and the second drive motor 26 utilizes the first sprocket 21, the chain 23 and the second sprocket 22 to drive the drive tube 15 to rotate, and the drive tube 15 drives the second spiral blade 16 and the inner cylinder 13 to perform synchronous rotation, and the inner cylinder 13 drives the first spiral blade 14 installed on the inner side of the inner cylinder 13 to perform synchronous movement, so that the material entering the buffer tube 9 is driven by the second spiral blade 16 to enter The inner tube 13 moves toward the discharge pipe 11 driven by the first spiral blade 14 in the inner tube 13; in this process, the steam delivery pipe 38 receives the superheated high-pressure steam delivered by the steam boiler, and continues to be delivered along the steam delivery pipe 38 toward the driving pipe 15 after the flow rate is adjusted by the regulating valve 41. During this period, the flow parameters are fed back by the gas flow sensor 39 and the temperature sensor 40.

After completing the adjustment process, the material is transported to the discharge pipe 11, discharged through the second star-shaped air lock 12, and then sent to the next process for further processing. The steam that has not been liquefied enters the gap between the outer tube 10 and the inner tube 13 and is discharged from the steam discharge pipe 24 , while part of the steam is liquefied after contacting the outer tube 10 and exchanging heat with the air to form condensate which is discharged through the condensate discharge pipe 25 .

The speed of the material to be tempered conveyed to the tempering equipment is fed back by the gravity sensor 3, and the conveying speed of the material to be tempered conveyed into the feed pipe 7 can be adjusted by the output power of the second drive motor 26 installed on the first star-shaped air lock 6; by adjusting the output power of the first drive motor 20, the drive pipe 15 can be adjusted to further adjust the conveying speed of the material to be tempered in the buffer tube 9 and the inner tube 13. Combined with adjusting the opening of the regulating valve 41, the conveying flow rate of the superheated high-pressure steam can be adjusted, so that the material to be tempered is fully in contact with the continuous steam during the movement of the buffer tube 9 and the inner tube 13 to the discharge pipe 11, thereby improving the effect of material tempering treatment and ensuring efficiency, which is worthy of promotion.
