Fluidized bed drying equipment

Abstract

The invention discloses fluidized bed drying equipment. The equipment integrally designs a material drying system, a separation system and a collection system based on the fluidizing drying technologyand the centrifugal principle, and materials have the advantages that heating is uniform, the time in a drying roller can be adjusted, the drying speed is high, products obtained after material drying are separated thoroughly, multiple dried articles can be collected at the same time, and the automation degree is high. A box body is composed of an inner heat conduction layer, a middle heating layer and an outer heat preservation layer, the heat energy utilization rate is high, a temperature controller and a timer are arranged, and therefore automatic control is achieved; temperature distribution in a fluidized bed is uniform, and the heat transfer effect is good; and the temperature and the air speed can be automatically controlled at the same time, the phenomenon of non-uniform partial heating of the materials is avoided, and the fluidized bed drying equipment is especially suitable for drying thermosensitive materials. The reliability of a screw feeding mechanism is high; a dust removal device can reduce the amount of dust in waste gas and is beneficial to environment protection; and the equipment structure is simple, and the fluidized bed drying equipment is suitable for beingused and popularized in drying and separating of crop and chemical products.

Description

technical field [0001] The invention relates to the technical field of agricultural and chemical machinery, in particular to a fluidized bed drying equipment. Background technique [0002] Drying equipment is a combination of a series of mechanical devices that remove unbound moisture on the surface of the material to be dried or other liquids through certain technical means, and is the core of the material drying process system. With the development of my country's industry and agriculture, a large number of agricultural and chemical products need to use drying equipment to realize the dehydration process. Fluidized beds are often used for drying materials due to their good mass and heat transfer effects. The working principle of the traditional fluidized bed drying equipment is: the material enters the dryer from the feed port, and under the action of the vibration force, the material moves forward continuously along the horizontal direction, and the hot air enters from th...

AI Technical Summary

Problems solved by technology

This dryer adopts the traditional hot air drying technology, and its mass and heat transfer effects are not good enough; manual feeding is required, and the dried pepper seeds and pepper shells are still mixed together, which cannot be separated, and the box can only be opened after drying manual collection
