Abstract

The utility model relates to a stone mill equipment for milling flour, which belongs to the field of a device for milling cereals and comprises a supporting rack (9) on which a mill bottom disc (8) is fixedly connected. A lower milling disc (7) is fixed to the mill bottom disc (8). The upper part of the lower milling disc (7) is connected with an upper milling disc (1). The utility model is characterized in that the supporting rack (9) is connected with a motor (11), wherein an output shaft of which is connected with a speed reducer (12). An output shaft of the speed reducer (12) is connected with a drive shaft (5) fixedly connected with the upper milling disc (1) after passing through the lower milling disc (7). Because the utility model adopts a stone mill to mill the flour and the low rotation speed of the milling disc of the stone mill leads to low temperature between the upper milling disc and the lower milling disc. Thereby, various nutritional ingredients, such as minerals, proteins, carbohydrates, vitamins of B1, B2, etc., in the flour are reserved. In addition, because the drive mode of the motor is adopted, processing efficiency is effectively enhanced. The utility model can be applied to small-size flour processing plants, family flour processing workshops and foods manufacturers, such as steamed bun plants, etc., for processing flour.

Description

Stone mill flour milling powder equipment

Technical field

The utility model belongs to the device field of the cereal of milling, and is specifically related to a kind of coaxial circles disc type grinding mill that vertical axis is arranged.

Background technology

In the northern area of China, common people like eating flour-made food, and particularly with the area of flour as staple food, annual flour demand is huge.Larger flour mill adopts the very high plant equipment of automaticity to grind flour, is provided with two and is grinding roller in relative rotation in these plant equipment, and wheat is milled into flour between grinding roller.The advantage that mechanization grinds flour is the productivity ratio height, but shortcoming also is obviously.In the process of machine stone roller system flour, for boosting productivity, the rotating speed operated by rotary motion of grinding roller is at 600 rev/mins, and the temperature that the rotation of the high speed of grinding roller produces is generally about 60 ℃.Under this temperature, nutritional labelings such as the protein in the flour, carbohydrate, fat, calcium, phosphorus, iron, vitamin B1, B2 almost exhaust.And in order to prevent the grinding roller excessive wear, often put into talcum powder, thereby cause pollution problem, be unfavorable for that people's is healthy in wheat the inside.Along with growth in the living standard, people more and more pay close attention to dietetic hygiene and nutritive value, and real pollution-free food more and more is subjected to common people's favor.In fact, a lot of rural areas in China, people get used to grinding system flour with stone mill, and this stone mill is made up of upper millstone, lower millstone and mill bed plate, by the frictional force between the last lower millstone wheat is pulverized into flour.With the flour of the stone mill system of grinding, the rotating speed of stone mill is very low, and the temperature between the stone mill is also very low, thereby multiple nutritional components such as the mineral matter in the flour, protein, carbohydrate, fat, calcium, phosphorus, iron, vitamin B1, B2 are kept.But traditional stone mill spurs by manpower or animal power, and production efficiency is extremely low.

The utility model content

The technical problem that the utility model solved is: a kind of stone mill flour milling powder equipment is provided, and this equipment can keep the nutritional labeling of flour, has improved working (machining) efficiency again, and pollution-free.

The scheme that its technical problem that solves the utility model adopts is: design a kind of stone mill flour milling powder equipment, comprise bracing frame, mill bed plate is fixedly connected on the bracing frame, fixing lower millstone on the mill bed plate, the top of lower millstone connects upper millstone, it is characterized in that connecting a motor on the bracing frame, and the output shaft of motor connects reductor, the output shaft of reductor connects a power transmission shaft, and power transmission shaft connects firmly mutually with upper millstone after passing lower millstone.

The utility model is offered corase grind blanking port and correct grinding blanking port on upper millstone, corase grind blanking port, correct grinding blanking port are through hole; The upper end of power transmission shaft connects firmly with upper millstone mutually by compressing tablet; The other end of power transmission shaft links by shaft coupling and speed reducer output shaft; The power shaft of reductor links by shaft coupling and motor output shaft.

The utility model is offered side opening on the periphery of upper millstone, insert short column in the side opening.

The beneficial effect that the utility model had is: owing to adopted stone mill to grind flour, the rotating speed of stone mill mill is low to cause the temperature between upper millstone and the lower millstone low, thereby multiple nutritional components such as the mineral matter in the flour, protein, carbohydrate, fat, calcium, phosphorus, iron, vitamin B1, B2 are kept; And because the mode that has adopted the motor transmission to drive, working (machining) efficiency has also obtained effective raising; Because the processing technology program that has adopted corase grind and correct grinding to be separated makes that the flour that grinds is more meticulous.The utility model can be applicable to small-sized flour mill, and family type flour adds workshop, also can make the usefulness of processing flour for food producers such as steamed bun factories.

Description of drawings

Below in conjunction with drawings and Examples the utility model is described further.

Fig. 1 is the structural representation of an embodiment of the utility model.

Among the figure, 1. upper millstone, 2. corase grind blanking port, 3. fastening bolt, 4. compressing tablet, 5. power transmission shaft, 6. correct grinding blanking port, 7. lower millstone, 8. mill bed plate, 9. bracing frame, 10. shaft coupling, 11. motor, 12. reductors, 13. shaft couplings, 14. short columns, 15. hollow core grindings.

The specific embodiment

As shown in Figure 1, the mill bed plate 8 that on bracing frame 9, is fixedly connected, fixing lower millstone 7 and the upper millstone of being made by granite 1 on the mill bed plate 8 offered correct grinding blanking port 6 and corase grind blanking port 2 on the upper millstone 1, correct grinding blanking port 6 and corase grind blanking port 2 are through hole, and the bottom of correct grinding blanking port 6 is a bellmouth.Connect a motor 11 on the bracing frame 9, the output shaft of motor 11 connects reductor 12, and the output shaft of reductor 12 connects a power transmission shaft 5, and power transmission shaft 5 passes lower millstone 7 and connects firmly mutually by compressing tablet 4 and fastening bolt 3 with upper millstone 1 with hollow core grinding 15 backs.

After motor 11 work, the output shaft of reductor 12 drives power transmission shaft 5, afterwards drive upper millstone 1 around hollow core grinding 15 rotations, wheat is earlier from roughly grinding in the gap that enters in the blanking port 2 between upper millstone 1, the lower millstone 7, upper millstone rotation back wheat is squeezed and is milled to fine grained, grind in the process at this, the blanking speed of wheat is very fast, and this process is the corase grind stage.And then the wheat fine grained after will roughly grinding is put in the correct grinding blanking port 6, the lower end diameter of correct grinding blanking port 6 is less, the speed of blanking has just reduced like this, the mixture that more fully forms flour and wheat bran that the wheat material is milled between upper millstone 1 and lower millstone 7 sieves this mixture from getting final product with square-bottomed bamboo basket.

After using a period of time, can there be a small amount of flour between upper millstone 1 and the lower millstone 7, for removing these flour.On the periphery of upper millstone 1, offer side opening, insert short column 14 in the side opening.After catching short column 14 by manpower or mechanical force upper millstone 1 is lifted, the flour between upper millstone 1 and the lower millstone 7 is scanned out get final product.
