Description

Technical Field

[0001] The utility model relates to the technical field of edible oil processing equipment, in particular to a vegetable oil refining and deodorizing device. Background Art

[0002] Refining and deodorization are necessary steps in oil processing. After decolorization, the crude oil enters the deodorization tank, where it is heated by water circulation and deodorized with the aid of high-temperature steam, which can effectively remove foreign flavors and odors in the oil.

[0003] The common vegetable oil refining and deodorizing devices currently on the market are mostly similar in structure. They are mainly made of stainless steel deodorizing tanks with water circulation pipes inside. Hot water flows through them. After the oil is injected into the deodorizing tank, it is continuously heated through water circulation, and then the high-temperature steam generated by the steam generator is passed into the oil. During the rising process of the steam, the water vapor passes through the oil and fat containing odor components, and the gas-liquid surface contacts each other. The water vapor is saturated with the volatile odor components and escapes according to the ratio of their partial pressures, thereby achieving the purpose of removing the odor components. In actual use, there are some functional deficiencies and there is room for improvement. For example, the outlet of the steam pipe used to export steam is in an open state. When the steam pressure is insufficient, there is a risk of oil backflow. In addition, when the steam is ejected from the open outlet, it is ejected in the form of an air mass, and the contact surface with the oil is small, and it does not have the function of diffuse jet to prevent backflow.

[0004] Now, a novel vegetable oil refining and deodorizing device is proposed to solve the above problems. Utility Model Content

When a worker approaches, the proximity sensor senses that an object is approaching, and the loudspeaker immediately broadcasts a reminder, thereby improving the worker's safety awareness and prevention awareness and reducing the chance of accidental scalding. The mounting plate provides physical support for the installation and fixation of the shell, thereby realizing the function of reminding pedestrians approaching. BRIEF DESCRIPTION OF THE DRAWINGS

The spherical cover 13 can limit the height of the spraying. As the oil in the guide cylinder 10 is sprayed out, the internal pressure is reduced, and the external oil enters along the oil inlet 11, forming a flow cycle of the oil. In the continuous circulation flow, the high-temperature steam takes away the grease containing odor components in the oil and discharges it from the exhaust gas outlet 9. The one-way valve nozzle 6 can prevent the oil from flowing back into the steam delivery pipe 4. Hot water enters the hot water coil 19 along the hot water inlet 14.
