Drying device and system and drying method

Abstract

The invention discloses a drying device comprising a drying module, a water supply module, a heat exchange module and a steam supply module. The drying module comprises a drying inner cavity and a drying outer cavity. A jacket is formed by the gap between the drying inner cavity and the drying outer cavity. The jacket communicates with the head and the tail of the water supply module through pipelines. The water supply module communicates with the head and the tail of the heat exchange module through pipelines. The steam supply module communicates with the drying module / heat exchange module through pipelines correspondingly. According to the drying device, a drying system and a drying method, heat is supplied to the jacket in the drying module through constant-temperature water flow or constant-temperature steam to dry materials stored in the drying inner cavity of the drying module, the temperature control can be accurate to + / -1 DEG C, quality of products obtained through drying canbe ensured through the constant-temperature drying condition, no manual operation is needed in the whole drying process, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of drying, in particular to a drying device, system and drying method. Background technique [0002] A crystal is a solid substance composed of atoms or molecules that are periodically and repeatedly arranged in space according to a certain law. The crystal has an internal structure that is arranged according to a certain geometric law. The three-dimensional space is periodically arranged repeatedly. Crystals are used in a wide range of fields, so the demand is very large. However, the crystal drying process has very strict temperature requirements. The existing technology can only achieve small-scale production and cannot meet the urgent needs of large-scale production. [0003] In the prior art, the constant temperature oven drying method is generally used to dry the crystals, but the constant temperature oven has the disadvantages of large temperature difference and uneven temperature during the drying p...

Problems solved by technology

Crystals are used in a wide range of fields, so the demand is very large. However, the crystal drying process has very strict temperature requirements. The existing technology can only achieve small-scale production and cannot meet the urgent needs of large-scale production.

[0003] In the prior art, the constant temperature oven drying method is generally used to dry the crystals, but the constant temperature oven has the disadvantages of large temperature difference and uneven temperature during the drying process, so it is difficult to obtain constant temperature drying conditions, resulting in the quality of the dried products cannot be guaranteed , the products in the oven are easy to be baked and the quality is unqualified, which is not conducive to quality control; and the collection of products in the constant temperature oven is more troublesome, it needs to rely on manual and careful operation, it is highly dependent on the proficiency of the operator, and the production efficiency is low
