Description

Technical Field

[0001] This utility model relates to the field of equipment for processing feed additives, and more specifically, to a drying device for nutrient supplements. Background Technology

[0002] Organic micronutrient supplements (such as organic salts, amino acid chelates / complexes, and hydrolyzed protein salts) are commonly used in feed. Compared to inorganic micronutrients, these products have better structural stability, higher biological value, and are easier to digest and absorb. They can improve the storage stability of oils and vitamins in compound premixes, reduce the loss rate of oils and vitamins in premixes, and thus improve feed quality and utilization. Therefore, it is a new type of environmentally friendly and efficient feed additive, and is currently widely used in the feed industry.

[0003] After searching, it was found that the application number CN201920728934.5, entitled "Drying Apparatus for Organic Micronutrient Supplements", proposed that the existing drying methods for organic micronutrient supplements are generally divided into three types: one is drying with an oven, the second is drying with a fluidized bed, and the third is drying with centrifugal spray. Oven drying easily causes variable-valence metal elements in the product to change their valence, thus damaging the product structure. It is also inefficient and cannot produce granular products. Centrifugal spray drying cannot produce granular products. Fluidized bed drying, while producing some granular products, results in irregular and uneven particles, with a proportion generally not exceeding 60%. Furthermore, the moisture content of the products using these three drying methods is difficult to guarantee below 10%. A structure combining a pressure spray drying tower and a fluidized bed addresses this issue. The product after pressure spray drying is granulated and most of its moisture is dried before entering the fluidized bed, resulting in uniform particles with lower moisture content. Simultaneously, connecting the pressure spray and fluidized bed to a dust removal system, and sending solid materials from the dust removal system to the spray drying tower via a fifth pipe, can improve the granulation rate and reduce the amount of powdery material. However, in practical use, this application requires large and complex equipment such as a drying tower, fluidized bed, and dust removal system. Matching the working time intervals of each device is difficult, leading to long waiting times and affecting the continuity of work. Additionally, the overall equipment is complex, cumbersome to use, and costly. Further improvements are possible.

[0004] There are currently no effective solutions to the problems in the relevant technologies. Utility Model Content

When drying nutrient supplements, the nutrient supplement raw materials can be put into the top surface of the second conveyor belt 4 through the feed inlet 17, and then enter between the second conveyor belt 4 and the first conveyor belt 2 as the second conveyor belt 4 is conveyed. After being squeezed by the first pressure roller 3 and the second pressure roller 5, the moisture in the raw materials is initially squeezed out. Subsequently, the raw materials fall between the second conveyor belt 4 and the third conveyor belt 9, and after being squeezed by the third pressure roller 6 and the fourth pressure roller 10, the moisture is squeezed out again. This process can quickly and continuously squeeze out the moisture in the raw materials, which is convenient for subsequent drying and improves the drying speed and efficiency. At the same time, the whole process does not require heating and can be operated at low temperature, avoiding the loss of nutrients and improving work efficiency.

[0031] In one embodiment, multiple sets of first pressure rollers 3, second pressure rollers 5, third pressure rollers 6, and fourth pressure rollers 10 are arranged at equal intervals. The first pressure roller 3 rolls against the first conveyor belt 2, the second pressure rollers 5 and 6 roll against the second conveyor belt 4, and the fourth pressure roller 10 rolls against the third conveyor belt 9.

[0032] In one embodiment, nozzles 14 are arranged above and inside the fourth conveyor belt 13, and blowers 15 are connected through the surface of the nozzles 14. A fan 20 is fixedly installed on the back side of the drying box 1, and the output end of the fan 20 is connected through the nozzles 14 via an air supply pipe 19. A granulating roller 16 is installed below the other end of the fourth conveyor belt 13.

After the raw material is squeezed and drained, it falls onto the top surface of the fourth conveyor belt. The blower 20 is started to generate flowing air, which is blown out bidirectionally through the blowers 15 to quickly dry the raw material. The dried raw material enters between the granulating rollers 16 and is squeezed by the granulating rollers 16 to form granules.

[0036] Working principle:

[0037] During the drying of nutrient supplements, the raw materials can be fed from the inlet 17 onto the top surface of the second conveyor belt 4. As the raw materials are conveyed by the second conveyor belt 4, they enter the space between the second conveyor belt 4 and the first conveyor belt 2. After being squeezed by the first pressure roller 3 and the second pressure roller 5, the moisture in the raw materials is initially squeezed out. Subsequently, the raw materials fall between the second conveyor belt 4 and the third conveyor belt 9, where they are squeezed again by the third pressure roller 6 and the fourth pressure roller 10. This rapid and continuous extraction of moisture from the raw materials facilitates subsequent drying and improves the drying efficiency. The drying speed and efficiency are high. At the same time, the entire process does not require heating and can operate at low temperatures, avoiding nutrient loss and improving work efficiency. Meanwhile, the raw material after being squeezed and drained falls onto the top surface of the fourth conveyor belt. The blower 20 starts to generate flowing air, which is blown out bidirectionally through the blower 15 to quickly dry the raw material. The dried raw material enters between the granulating rollers 16 and is squeezed by the granulating rollers 16 to form granules. The granulation is uniform, efficient and continuous, which further improves work efficiency. The overall structure of this device is simple, easy to use and continuous, and significantly improves the overall work efficiency.
