Epoxy soybean oil drying device and drying method thereof

Abstract

The invention discloses an epoxy soybean oil drying device and a drying method thereof. The apparatus comprises a drying tank, a steam outlet and a feed inlet are arranged on the drying tank, a discharge hatch is arranged below the drying tank, a material distributor connected to the feed inlet is arranged on an upper segment of the drying tank, a vacuum pipeline used for dewatering the material under negative pressure is connected with the steam outlet, a filling device connected with the material distributor is arranged on an intermediate segment in the drying tank and is used for dispersing the material; and a heater is used for heating and drying the material, which is positioned below the filling device and arranged at a lower segment in the drying tank. The drying device is capable of uniformly distributing the materials through the material distributor, so that a vaporization rate can be increased by heating the material, a problem that equipment cannot continuously operate due to material coking and filling material obstruction can be solved, equipment maintenance cost is reduced, production efficiency is obviously enhanced, product quality is stabilized, and energy can be saved.

Description

technical field [0001] The invention relates to a drying device and a drying method of epoxidized soybean oil. Background technique [0002] Epoxy soybean oil (ESO) belongs to epoxy plasticizer, is a widely used polyvinyl chloride (PVC) plasticizer and stabilizer, has good heat and light stabilizing effect, compared with ester plasticizer It has the advantages of extraction resistance, migration resistance, volatility resistance, good compatibility and degradability. It is the only epoxy plasticizer that can be used in food packaging materials. It is a good substitute for phthalate plasticizers. It fully complies with the EU RoHS environmental protection directive and the US FDA food additive rules, which has attracted the attention of more and more plastic processing industries and plasticizer manufacturers. At present, the annual output and consumption of phthalate plasticizers in my country The amount of plasticizers accounts for more than 80% of the total plasticizers, and...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the above-mentioned deficiencies in the prior art, the present invention provides a drying device for the production of epoxidized soybean oil, which distributes the material evenly through the material distributor in the upper section to the filler in the middle section, so as to increase the ratio of the material to the greatest extent. Surface area, reduce wall flow, increase vaporization rate, accelerate water evaporation, further heat the material in the lower section to increase vaporization rate, solve the problem of material coking and plugging packing, causing equipment to not continue to operate, reduce equipment maintenance costs, and significantly improve production Efficiency, stable product quality and energy saving
