Description

Technical Field

[0001] The utility model relates to the technical field of desolventizing devices, in particular to a low-temperature desolventizing device for rice bran meal. Background Art

[0002] Desolventizing units are primarily used in industrial processes to remove solvents from leached or extracted materials to obtain a dry product. This process typically involves heating and vacuum conditions to promote solvent evaporation and reduce thermal damage to heat-sensitive materials.

[0003] Common rice bran meal low-temperature desolventizing devices generally use fans to cool the interior to reduce thermal damage to sensitive components such as protein in the rice bran meal, maintain the nutritional value and quality of the product, and install filters at the air inlet of the ventilation pipe to prevent dust from entering the interior of the device.

[0004] However, since the filter is vibrated when it is cleaned, the dust on its surface will enter the air duct through the holes in the filter. As a result, when the interior of the device is subsequently cooled, the dust that falls into the air duct will inevitably be sucked into the device and mixed with the surface of the rice bran meal, thereby reducing the quality of the rice bran meal desolventizing.
