Desolventizing humidifier

Abstract

The invention provides a desolventizing humidifier which comprises a tank body, multi-layer sieve plates, a steam plywood case I and a discharge device. The multi-layer sieve plates are fixed in the tank body, the steam plywood case I is fixed on the tank body and arranged at the bottoms of the multi-layer sieve plates, and the discharge device is arranged in the tank body. The tank body comprises a steam outlet, a feed port and a discharge port, wherein the steam outlet is arranged at the top, the feed port is connected with a feed device, and the discharge port is arranged at the bottom of the tank body. The discharge device comprises a vertical shaft arranged in the center of the tank body and a drive mechanism driving the vertical shaft to rotate. A distribution device, scraper boards, a harrow rod I and a harrow rod III are fixed successively on the vertical shaft from top to bottom. The scraper boards are arranged above and matched with the multi-layer sieve plates, the harrow rod I is introversive and arranged above and matched with the steam plywood case I, and the harrow rod III is extroversive and arranged above and matched with the tank body bottom. Steam is fed into the steam plywood case I, and steam outlets are arranged on the upper portion of the steam plywood case I. Compared with the prior art, the desolventizing humidifier has the advantages of being high in solvent recovery rate and dephenolized cottonseed protein quality.

Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to a dephenolized cottonseed protein processing equipment, specifically a desolventizing humidifier. Background technique [0002] At present, in the cottonseed protein production line, after the dephenolized material is dried by a disc dryer, a part of the solvent still remains in the material, which cannot be completely recovered. One of the existing technologies is to use a disc dryer to recycle the residual solvent, but the disc dryer indirectly heats the material and uses a small amount of direct steam to evaporate the material. Since the steam and the material cannot Complete contact, the recovery effect is not ideal, resulting in high solvent consumption, which affects the economic benefits of the enterprise. [0003] In the prior art, there is also a method of secondary recovery of the residual solvent through the evaporation machine. The evaporation machine uses a large...

AI Technical Summary

Problems solved by technology

[0002] At present, in the cottonseed protein production line, after the dephenolized material is dried by a disc dryer, a part of the solvent still remains in the material, which cannot be completely recovered

One of the existing technologies is to use a disc dryer to recycle the residual solvent, but the disc dryer indirectly heats the material and uses a small amount of direct steam to evaporate the material. Since the steam and the material cannot Complete contact, the recovery effect is not ideal, resulting in high solvent consumption, which affects the economic benefits of the enterprise

[0003] In the prior art, there is also a method of secondary recovery of the residual solvent through the evaporation machine. The evaporation machine uses a large amount of steam to evaporate the solvent in the high material layer, but due to the thick material layer, the material in the equipment If the residence time is long, the color of the material will become darker, the protein will be denatured, and the quality of the product will decrease.

[0004] In summary, the existing secondary desolventization equipment has problems such as low solvent recovery rate, long recovery time, denaturation of cottonseed protein after dephenolization, etc.
