Abstract

The invention discloses a vertical steam removal device for a residual solvent in rapeseed meal. The vertical steam removal device comprises a vertical steam removal machine composed of six layers of box bodies, wherein the bottom plates and side walls of the lower five layers of box bodies are provided with heated steam jackets, the bottom of the topmost layer of box body is provided with an annular steam pipe on which a plurality of steam pipes are obliquely arranged; each layer of box body is internally and respectively provided with a material height indicator and an automatic material door capable of automatically regulating the dropping speed of an upper-layer material according to the height of a local-layer material; a material seal conveying stranding cage is connected with the upper end of the topmost layer of box body, and the bottommost layer of box body is provided with a cock discharging valve; each layer of box body is provided with an agitating scraper, the agitating scrapers are fixed on a main shaft, and the main shaft is fixed in the box bodies and can rotate; and the topmost layer of box body is connected with a shell pass of a tubular heat exchanger through a cyclone dust catcher and is finally connected with a connecting pipe of a water distribution tank. The vertical steam removal device is used for solving the technical problems of rapeseed meal steam removal difficulty, high steam consumption in steam removal and high extraction solvent consumption and is suitable for large-scale industrial processing; and in addition, the automatic material door is simple in working principle, reliable and convenient to operate.

Description

technical field [0001] The invention relates to a vertical device for evaporating residual solvent in rapeseed meal. Background technique [0002] Rapeseed oil is a popular edible oil, and its production volume is particularly large. The processing technology of rapeseed oil is generally pre-pressed and then leached. After the leaching is completed, the rapeseed meal needs to be evaporated to recover and remove the residual solvent. , so that rapeseed meal can be used as animal feed, fertilizer, etc. [0003] Due to the large production of rapeseed oil, the amount of rapeseed meal that needs to be evaporated is also very considerable, and the evaporation needs to consume a lot of steam and energy. Reducing energy consumption can significantly save energy and reduce emissions. The existing device for steaming and removing the residual solvent in rapeseed meal has not reached a satisfactory level, and there is still a lot of room for improvement. Contents of the invention ...
