Energy-saving feed particle drying equipment

Abstract

The invention discloses energy-saving feed particle drying equipment. The energy-saving feed particle drying equipment comprises a storage hopper, a feeding pipe and a drying box. The drying box communicates with the lower end of the storage hopper through the feeding pipe. A first preheating jacket sleeves the outer side of the feeding pipe, the first preheating jacket communicates with the innercavity of the drying box through a first communicating pipe. A second preheating jacket sleeves the outer side of the storage hopper, the second preheat jacket communicates with the first preheat jacket through a second communicating pipe, and the second preheating jacket communicates with an exhaust pipe. According to the energy-saving feed particle drying equipment, through a drying cylinder being a hollow cone, a drum, a rotating joint and an air heater, the uniform blowing of hot air from meshes of the drying cylinder is realized, feed particles spread and sliding down from the surface ofthe drying cylinder are evenly and efficiently dried, and the drying uniformity and the drying effect are improved; and the feed particles are preheated by arranging the first preheat jacket and thesecond preheat jacket, subsequent drying is facilitated, and meanwhile, heat is used fully.

Description

technical field [0001] The invention relates to the field of energy-saving drying equipment, in particular to an energy-saving feed particle drying equipment. Background technique [0002] Drying is one of the most important processes in extruded feed processing. The moisture content of the feed pellets just extruded from the extruder is very high, reaching more than 22%. It must be equipped with drying equipment to remove more than 10% of the moisture and then cooled to ensure that it reaches the qualified product quality. At present, the supporting drying equipment in domestic extruder feed processing mostly uses conveyor belts and chain-type crate dryers. This type of equipment is of horizontal structure, which occupies a large area and is expensive. Most of the newly built factories still rely on imports. At the same time, in actual production, there are still problems such as large fan power, high energy consumption for drying, steam consumption per ton of material is...

Problems solved by technology

This type of equipment is a horizontal structure, which occupies a large area and is expensive. Most new factories still rely on imports.

At the same time, in the actual production, there are still problems such as large fan power, high drying energy consumption, steam consumption of more than 500kg per ton of material, and blockage of sieve (mesh) holes, which significantly increase the processing cost of extruded feed and affect its popularization and application.
