Description

Technical Field

[0001] This utility model relates to the field of white oil production equipment, specifically to a white oil filtration and blending system. Background Technology

[0002] Currently, shortening, scientifically known as white oil, is a specialized oil in the food industry due to its snow-white appearance and resemblance to lard. It possesses a certain degree of plasticity or viscosity and is used as an ingredient in pastries, for surface coating, or for demolding. It is used to crisp or soften baked goods, prevent proteins and carbohydrates from hardening and clumping together during processing, and improve texture. On white oil production lines, the raw material needs to be filtered before further processing. Existing filtration devices are prone to clogging and have slow filtration speeds. There is a lack of a white oil filtration device that offers fast filtration speed and is less prone to clogging.

[0003] Most existing blending equipment for finished white oil production uses a single type of agitator, such as a standard paddle agitator. This only generates a unidirectional flow of agitation, resulting in insufficient mixing of the white oil within the tank and the presence of dead zones. This is particularly problematic for blending high-viscosity white oils or those with multiple added ingredients, making it difficult to achieve uniform mixing and affecting the quality stability of the white oil product.

[0050] Example 1: As shown in the attached diagram, the white oil raw material moves along the direction of the arrow during filtration. The white oil raw material is added through the raw material inlet 6 and first falls into the buffer area between the diversion hood 13 and the outer filter cylinder 2. The liquid level of the white oil raw material in the buffer area continuously rises, and after submerging the top surface of the diversion hood 13, it flows evenly into the diversion hood 13. It then falls into the inner filter cylinder 1 through a set of flow holes 14. As the white oil raw material in the inner filter cylinder 1 continues to rise, the stirring and discharge mechanism 3 is activated, continuously agitating the white oil raw material. The pressure of the white oil raw material causes it to quickly flow out through the filter holes 4 into the filtration area 8. The filtered white oil raw material is discharged to the next station through the filter outlet 7. Raw material impurities remaining at the bottom of the inner filter cylinder 1 are periodically discharged by opening the drain valve. During stirring, the stirring and discharge mechanism 3 continuously scrapes off the white oil adhering to the inner wall of the inner filter cylinder 1 using the scraper 12, preventing blockage of the filter holes 4. When it is necessary to test whether the white oil filtration is qualified, a sampling pipe 15 can be connected to take a sample.

[0051] The motor and reducer are installed on the top of the outer filter cylinder 2. The rotating shaft 9 passes through the shaft hole at the center of the top of the outer filter cylinder 2 and extends into the inner filter cylinder 1. The rotating shaft 9 is connected to the outer filter cylinder 2 and the flow divider 13 by a packing seal.

[0052] The white oil feed pipe and the functional additive feed pipe respectively deliver refined white oil raw materials and functional additives to the two inlets of the turbine dynamic pipeline mixer. After initial mixing, they flow through the raw material feed interface at the top of the blending vessel and enter the blending vessel body. Then, they are stirred and mixed by multiple sets of horizontal stirring rods of the stirring paddle assembly, combined with the aeration and dispersion of the pulse air pump and the bottom reflux of the return pump, to achieve uniform mixing of refined white oil raw materials and functional additives.
