Description

Technical Field

[0001] The utility model relates to the technical field of oil processing, in particular to a desolventizing device for subcritical extraction of animal oil. Background Art

[0002] Grease desolventizing refers to a series of process steps in industrial production to separate grease from a mixture. Its working principle is to use a vacuum pump to create a working environment with a stable vacuum degree of about 7000 Pa, then heat the grease to a subcritical state, and then use high-temperature steam to separate the impurities remaining in the grease.

[0003] When desolventizing, first turn on indirect steam to raise the oil temperature to 100°C. Then, introduce direct steam at a pressure of about 0.1 MPa to fully stir the oil in the pot. Continue to use indirect steam to raise the oil temperature to 140°C. At the same time, start timing and desolventizing, which generally lasts for four hours.

[0004] During the steam stripping process of the existing desolventizing device, the broken bubbles often stick to the inner wall of the device, making it difficult to clean them quickly. Therefore, we propose a desolventizing device for subcritical extraction of animal oil. Utility Model Content

When the control device is working, the animal oil is first added to the desolventizing tank through the feed pipe, and then heated to make the animal oil reach the subcritical temperature condition, and then steam is sprayed through the steam spray device to continuously desolventize. When the bubble fragments of the animal oil splash onto the desolventizing tank, they are cleaned by the scraper. When the steam spray device is controlled to work, the high-temperature steam enters the jet pipe through the second inlet pipe, and then is evenly sprayed into the vegetable oil through each jet nozzle to continuously desolventize the vegetable oil.

[0008] Furthermore, the desolventizing device also includes a motor, which is fixedly connected to the middle of the upper surface of the desolventizing tank.
