Abstract

An oil and fat decolouring apparatus comprises a decolouring machine, a drive motor, material discharge pipes, a material collection pipe, a centrifuge and a fixed bracket. An upper cover of the decolouring machine is equipped with a vacuum device that is used for storing oxygen adsorbent. A rotary shaft of the drive motor, which is positioned below the decolouring machine, is equipped with the material collection pipe and the centrifuge. Four centrifugal chambers are equipped in the case of the centrifuge. An oil outlet pipe is positioned on the bottom of the centrifuge. The lower part of the decolouring machine is equipped with two material discharge pipes that enter the material collection pipe. A branch pipe of the material collection pipe is inserted into the bottom of the centrifuge. The oxygen adsorbent equipped in the vacuum device of the production takes chemical reaction with oxygen in the hollow chamber on the upper part of the decolouring machine and absorbs oxygen, producing a vacuum state. The production is fine in decolouring effects, simple in structure, small in shape, convenient for maintenance and low in cost.

Description

The grease-decolor device

This is practical to relate to a kind of grease-decolor device, particularly relates to a small-sized decolouring device that is suitable for civilian polished fat.

Decolouring is the important procedure in the oil and fat refining commercial run, and the natural pigment and the work in-process that exist in the grease are removed because of the external pigment of oxygen generation, improves oil quality.Industrial grease-decolor divides intermittent vacuum decolouring and continous vacuum decolouring.Continous vacuum decolouring device has tower and duct type abroad, domestic only have tower, tower decolouring device main body structure is cylinder laminar or dividing plate seal tower, produce main vacuum condition by multistage vacuum pump, the circulation of oil between each tower layer moves by valve formula divider plate passages to be undertaken, and between each tower layer connection is arranged all, and each tower layer all is equipped with by what the motor of cat head and deceleration device drove and is positioned on a pair of stirring blade on the same axle, though, still can not avoid short circuit and long-term trapping phenomena through multistage stirring.Decolorizing effect is poor.External duct type decolorizer is that the hard straight upside-down mounting pipeline by U-shaped constitutes, and becomes bevel at the bottom of the U-shaped pipe, good decolorizing effect, but because of being an one-piece construction, maintenance is used inconvenient.

The purpose of this utility model provides a kind of good decolorizing effect, and moulding is small and exquisite, and easy access is simple to operate, grease-decolor device easy to use.

The utility model is realized by following technical scheme: the utility model comprises and has whipping appts, vacuum, thermowell, purging valve, the decolorizer of electric heating tube and driving motor, discharge nozzle, aggregate pipe, sedimentator and fixed support, it is characterized in that: the decolorizer loam cake that is arranged on the fixed support is equipped with the vacuum that holds oxygen absorbent, aggregate pipe and sedimentator are equipped with in the position in the driving motor rotating shaft of decolorizer bottom, interior four circumferential uniform division plates of the housing of sedimentator and inner walls and the position oil outlet pipe outer wall at middle part, housing bottom surface constitute four centrifugal chambers, sedimentator housing circular bottom part edge is provided with sedimentation tank, the decolorizer bottom is provided with two discharge nozzles and enters in the aggregate pipe, is in charge of the centrifugal chamber bottom that feeds sedimentator for four on the aggregate pipe.

The utility model has the advantages that owing to be equipped with vacuum in the decolorizer, make grease under vacuum condition, decolour, thereby the external pigment of having avoided Oxidation of Fat and Oils to produce, improved decolorizing effect, and sedimentator can quicken separating of decolouring grease and absorbent, easy to use, simple in structure, moulding is small and exquisite, and maintenance is convenient, and is cheap.

Knot and description of drawings most preferred embodiment of the present utility model.
