Abstract

The invention relates to a stone mill and in particular relates to an oil mill for processing sesame oil from sesame. The oil mill is divided into an upper mill sheet and a lower mill sheet and is characterized in that a mill navel is formed in the center of the upper mill surface of the lower mill sheet; small and thin mill teeth with the lengths within 3-12cm are radially arranged at the outer edge of the lower mill sheet; a mill navel sleeve is arranged in the center of the lower mill surface of the upper mill sheet; small and thin mill teeth with the lengths within 3-12cm are radially arranged at the outer edge of the upper mill sheet; one or more mill hole are formed near the inner section part of each small and thin mill tooth; an arc centrifugal fan-shaped upwardly-concave material feeding groove with gradually small transition depths is formed in the outer part of each mill hole. When the chamber-stagnation-free oil mill works, a raw material does not pass through a mill chamber and large and thick teeth, so that the raw material cannot be stagnated in the mill chamber and the large and thick teeth, and the problem of the chamber stagnation is solved; the problem of the chamber stagnation is solved, the arc centrifugal fan-shaped upwardly-concave material feeding groove with the gradually small transition depths is formed in the outer part of each mill hole, the small and thin mill teeth are lengthened to 3-12cm, the feeding amount is increased and the rotation rate is increased, so that the oil milling efficiency of the oil mill is improved.

Description

Not stagnant thorax oil abrasion

Technical field

The present invention relates to a kind of stone mill, specifically the oil abrasion of sesame oil processed by a kind of sesame.

Background technology

The stone mill of current use is divided into dry grinding (flour mill), wet-milling (soya-bean milk mill) and oil abrasion (Special grinding with sesame processing sesame oil).The structure of oil abrasion is stacked together with the round pie stone that two block sizes are equal, and there is iron axle at the top bevel center of lower fan abrasive disc, is called mill navel, has large corase grind tooth radially outside mill navel, is radial little fine grinding tooth outside large corase grind tooth, the center of the bed stone of upper fan abrasive disc is mill navel cover, the outer 5cm place of mill navel cover leads directly to two symmetrical wear eyes up and down, it is radial large corase grind tooth outside wear eye, it is radial little fine grinding tooth outside large corase grind tooth, the upper and lower large corase grind tooth of two fan abrasive discs and the length of little fine grinding tooth are than being 4:1, number ratio is 1:5, the function of wear eye is that sesame is transported to the middle gap of two fan abrasive discs, this gap is called mill thorax, another function of wear eye is ventilated, when upper fan abrasive disc rotates, the large corase grind tooth of upper fan abrasive disc produces centrifugal cyclone, mill thorax in sesame in the groove of lower fan abrasive disc outwards centrifugal blow be passed to fine grinding tooth wear into sesame slurry, and then enter next and put forward oily operation, this oil abrasion when rotating speed low, centrifugal wind is little, when can not blow sesame, or conveying amount excessive time, large corase grind tooth easily extrudes sesame and is brokenly sticky in together up and down, produce stagnant thorax phenomenon, stagnant thorax phenomenon is because the sesame fried is very crisp, pressurized will pulverize powder a little, Powdered pressurized again will become greasy filth shape, greasy filth shape easily sticks together, can not outside centrifugal output, just stagnate in mill thorax and in large bastard, upper fan abrasive disc just must be taken apart once produce stagnant thorax phenomenon, remove the stagnant thing in large bastard and mill thorax, then could work after ressembling.In order to prevent stagnant thorax phenomenon, only have the method reducing feed quantity and lengthen working hours at present, therefore mill oil is referred to as " suffering oil ", the oil abrasion efficiency used at present is all very low.

Summary of the invention

Technical problem to be solved by this invention is: provide one not stagnant thorax oil abrasion, and it can improve the mill oil efficiency of oil abrasion.

The technical scheme that the present invention takes is: this oil abrasion profile is the same with traditional oil abrasion, and be divided into upper and lower two fan abrasive discs, it is characterized in that: there is mill navel at the top bevel center of lower fan abrasive disc, there is the little fine grinding tooth that 3-12cm is long radially abrasive disc outer; The bed stone center of upper fan abrasive disc is mill navel cover, and there is the little fine grinding tooth that 3-12cm is long radially outer, at the inner segment position by broadcasting this little fine grinding tooth nearly, having one or more wear eye, having circular arc centrifugal fan-shaped transition gradually shallow fovea superior feed-sowing groove outside wear eye.

Have circular arc centrifugal fan-shaped transition gradually shallow fovea superior feed-sowing groove outside above-described wear eye, its structure and working condition are: the wear eye of upper abrasive disc does circular-rotation, and its movement locus is circular arc; Because there is rotation just to have centrifugal force, so raw material is just shed out in centrifugal fan-shaped after flowing out wear eye, transition is gradually shallow, be by deep trouth to shallow slot gradually transition until shallow slot disappear, so just can raw material sesame is first squeezed into Powdered, regrind and be twisted into slurry oil shape, two wear into flow-like by little fine grinding tooth; Because this feed-sowing groove is on the bed stone of upper fan abrasive disc, so this groove upwards caves in, so call recessed feed-sowing groove.

When the not stagnant thorax oil abrasion of the present invention works, raw material, without overground thorax and large bastard, therefore can not stagnate in mill thorax and large bastard, thus also just solve " stagnant thorax " problem; Because solve stagnant thorax problem and have wear eye cylindrical arc centrifugal fan shape transition gradually shallow fovea superior feed-sowing groove, add 1. little fine grinding tooth and be lengthened to 3-12cm; 2. inlet amount is strengthened; 3. rotating speed is improved, so the efficiency of the mill oil of this oil abrasion improves.

Detailed description of the invention

This oil abrasion profile is the same with traditional oil abrasion, be divided into upper and lower two fan abrasive discs, it is characterized in that: there is mill navel (2.1) at the top bevel center of lower fan abrasive disc (2), there is the little fine grinding tooth (2.2) that 3-12cm is long radially abrasive disc outer, the bed stone center of upper fan abrasive disc (2) is mill navel cover (1.1), there is the little fine grinding tooth (1.2) that 3-12cm is long radially outer, at the inner segment position by broadcasting this little fine grinding tooth (1.2) nearly, there is one or more wear eye, outside wear eye, have circular arc centrifugal fan-shaped transition gradually shallow fovea superior feed-sowing groove (1.4).

The concrete structure of feed-sowing groove (1.4) and working condition: the wear eye (1.3) of upper abrasive disc (1) does circular-rotation, and its movement locus is circular arc; Because there is rotation just to have centrifugal force, just shed out in centrifugal fan-shaped afterwards so raw material flows out wear eye (1.3), transition is gradually shallow, be by deep trouth to shallow slot gradually transition until shallow slot disappear, so just can raw material sesame be first squeezed into Powdered, regrind and be twisted into slurry oil shape, two wear into flow-like by little fine grinding tooth; Because this feed-sowing groove (1.4) is on the bed stone of upper fan abrasive disc (1), so this groove upwards caves in, so call recessed feed-sowing groove (1.4).

After adopting said structure, this oil abrasion not only overcomes stagnant thorax problem, and the efficiency of mill oil also improves.
