Material drying device for processing aquatic animal concentrated feed

Abstract

The invention discloses a material drying device for processing aquatic animal concentrated feed. When the material drying device is used for processing and drying the aquatic animal concentrated feed, a rotating drum is driven by a rotating drive assembly to rotate, high-pressure hot air and low-pressure hot air are respectively led into an inner air pipe and an outer air pipe by a hot air blower, the high-pressure hot air sprayed through a high-pressure spray pipe is used for blowing and spreading the aquatic animal concentrated feed, at least part of the aquatic animal concentrated feed overcomes the gravity and is blown away from the inner surface of the rotary drum, the high-pressure hot air is used for drying the aquatic animal concentrated feed, so that the drying uniformity is improved. The drying efficiency and the uniformity can be improved by adopting a high-pressure hot air flow raising method; the material is lifted to a certain height in a spiral rotating manner and thennaturally falls down, the hot air dries the material in the falling process of the material, so that all the material is uniformly dried; and the spiral rotating drum enables the material to be turnedwhen the material enters different spiral grooves, the material can be dried in all directions, so that the device is suitable for processing a large amount of material.

Description

technical field [0001] The invention relates to the technical field of processing concentrated aquatic feed, in particular to a drying device for processing concentrated aquatic feed. Background technique [0002] Aquafeed is bait specially provided for aquatic animal breeding. According to feeding species, aquatic feed can be divided into fish feed, shrimp feed and crab feed; according to feed characteristics, it can be divided into compound feed, concentrated feed and premixed feed. The raw materials for the production of aquatic feed are mainly composed of fishmeal, grain raw materials and oil. Fishmeal and grain raw materials often account for more than 50% of the feed cost. At present, the drying equipment on the market cannot dry the aquatic feed. The aquatic feed in the drying device is flipped, resulting in a slow drying speed inside the aquatic feed, which reduces the drying efficiency of the drying device.

Problems solved by technology

The raw materials for the production of aquatic feed are mainly composed of fishmeal, grain raw materials and oil. Fishmeal and grain raw materials often account for more than 50% of the feed cost. At present, the drying equipment on the market cannot dry the aquatic feed. The aquatic feed in the drying device is turned, resulting in a slow drying speed inside the aquatic feed, which reduces the drying efficiency of the drying device

[0003] A Chinese patent discloses a drying device for aquatic feed (authorized announcement number CN 207585245 U). This patented technology can shake the material to make the material turn and dry. However, in the case of more and heavier materials, the material cannot be turned thoroughly. , making it difficult for materials to be fully dried and difficult to meet a large number of production needs

Moreover, when the material is drying, it is easy to cause uneven drying and too long drying time, while the ordinary heating and drying method will easily lead to overheating of the position close to the heater, resulting in the loss of nutritional value of the feed, and the farther away The place where the drying is not good, it is easy to mold after a long time
