Milling machinery processing wheat process

Wheat--cleaning--watering--moistening wheat--grinding--grinding and sieving--powder-mixing--packaging

1. Cleaning: It is mainly to clean the straw, stones, damaged wheat and other impurities in the wheat that affect the flour yield. The main equipments are: wheat threshing machine, stone removal machine, wind selection, selection, etc. According to the quality of wheat and milling requirements, various flour mills will have some differences

2. Watering: After the wheat is cleaned, it needs to be watered to make the moisture of the wheat reach a certain content, which can improve the toughness of the wheat husk and reduce the mechanical strength of the wheat endosperm, so that the wheat husk should not be crushed during grinding. flour quality, and the conditioned endosperm results in lower roller wear and lower energy consumption in the mill. Generally, high-gluten wheat needs more water, and low-gluten wheat is relatively less.

3. Run wheat: Wheat soaked in water should be stored in the wheat warehouse for a certain period of time, generally 8 to 24 hours, depending on the variety of wheat and the temperature. High-gluten wheat generally takes longer, and it takes longer to moisten wheat in winter. The wheat after watering and moistening is called the milled wheat, and the moisture of the milled wheat is controlled at 14-16%. If it is too high, it will affect the subsequent screening.

4. Grinding and sieving: Distracted grinding system and skin grinding system, the mill crushes the wheat into large bran, small bran, large endosperm, small endosperm, coarse powder and fine powder, and then different materials enter different mills. Grinding with a powder machine, sieving and cleaning at the same time. This is a very complicated process that needs to be adjusted by experienced fans to achieve the best results. Finally get flour (1~3 kinds), coarse bran, fine bran.

5. Mixing flour: Due to the demand for special flour, one kind of wheat flour often fails to meet the requirements of customers. By mixing different wheat flours according to a certain proportion, various silty properties of the finished flour can be adjusted to meet customer requirements.

6 Lastly is the packaging.

Wheat flour milling/grinding machine equipment configuration, production capacity, process are different, prices are often different, profits, and peers are different, so we can't talk about it.

Main working parts of wheat flour milling/grinding machine

The grinding part is mainly composed of a hopper, a flow adjustment mechanism, a speed grinding roller, and a grinding roller spacing adjustment mechanism. The hopper is installed above the machine base, and there is a flow adjustment plate at the bottom to control the opening of the bottom port, which is adjusted by the flow adjustment mechanism.

Grinding rollers are the main working parts of the pulverizer. They are arranged in pairs at the lower part of the feeding port. The two rollers rotate opposite each other at different speeds to grind the materials into powder. The grinding roller is made of alloy cast iron by cold casting, the surface has sufficient hardness and strength, and has good thermal conductivity. There are two types of grinding rollers: smooth rollers and toothed rollers. The toothed rollers have high grinding efficiency, save electricity and are widely used.

The cylindrical screen (referred to as the round screen) is composed of a shell, a circular sealing screen, and a fan impeller. The shell is rolled into a cylinder by a thin iron sheet, the lower end is a powder outlet, and the end cover of the cylinder is a bran outlet. The screen frame of the cylindrical screen is equipped with a screen mesh, and the thickness of the screen mesh can be changed as required. The circular screen is equipped with a wind impeller, and there are two wind blades and two pig brown brushes on the wheel. The position of the brush can be adjusted so that the brush can always be brushed on the screen. The impeller is driven by the pulley to rotate, which plays the role of conveying and separating materials.

How to install wheat flour milling/grinding machine?

(1) Check whether the direction of power rotation is consistent with the direction of the arrow on the shell of the wheat mill;

(2) Check whether the tension of the drive belt is appropriate. If the transmission belt is too tight, the motor and bearing will heat up; if it is too loose, the transmission belt will slip, the productivity will decrease, and the grinding quality will also decrease accordingly, so the transmission belt should be tensioned to an appropriate degree;

(3) Check whether the two grinding discs are firmly installed, the fixing screws of the grinding discs are not allowed to be higher than the grinding discs, and whether the crushing gear and the toothed clutch are firmly installed;

(4) Check whether the adjusting screw can advance and retreat freely, and whether the spring can rebound the moving grinding disc in time;

(5) Check whether the silk screen is pressed tightly, and whether the fan blade of the round screen collides with or is far away from the screen frame. The fan blade should be about 5-7 mm away from the screen surface.

How to adjust wheat flour milling/grinding machine

(1) Adjustment of roller wheat flour mill

①Adjustment of feeding amount: The feeding amount is adjusted by the gap between the flow regulating plate and the slow roller. Generally, it depends on the size of the material particles and the working conditions.

②Grinding roller gap adjustment: The fine adjustment of the grinding roller gap is operated by adjusting the handwheel, and the adjustment amount for each turn of the handwheel is 0.04-0.06 mm; The fixed position of the end bearing arm on the tie rod, so that the slow roll moves closer to or away from the fast roll. The adjustment amount for each turn of the positioning nut is 0.2~0.4mm.

The gap between the grinding rollers can be checked visually or with a thin iron sheet, or a thin paper strip of the same width as the grinding roller can be inserted between the two grinding rollers, turn the adjusting handwheel to adjust the rolling distance, turn the transmission belt by hand, and observe the paper strip being rolled. traces are consistent. If the marks are uneven, the length of the rod or the pressure of the pressure spring can be adjusted.

③ Selection of the arrangement of grinding rollers: The grinding roller is the main working part of the mill. The surface of the grinding roller is made of fine and dense helical teeth by broaching, which has strong grinding ability. Grinding teeth are divided into sharp angle and obtuse angle. The tooth shape of the newly drawn grinding roller should be blunt to blunt; when the grinding roller tooth shape is worn out, the productivity will be significantly reduced. , so that the tooth shape arrangement is blunt and opposite to the front; when the grinding roller tooth tip is further worn and the productivity is lower, the fast roller is turned around so that the grinding teeth are arranged in front to front. When the grinding teeth are ground into a larger plane, the teeth should be redrawn.

④Adjustment of wall plate and long sliding plate: The left and right wall plates are used to prevent the material from leaking from both ends of the grinding roller without being ground. The gap between the left and right wall plates and the grinding roller is subject to no grain leakage. Whenever the grinding roller pulls the wire once or replaces the grinding roller, the long slide plate needs to be adjusted to prevent grain leakage or friction of the grinding roller. When adjusting, loosen the bolts and turn the crank, so that the long sliding plate and the slow roller should maintain a gap of 1.5~2 mm.

⑤Adjustment of the round screen part After the round screen has been used for a period of time, the silk screen will become loose. At this time, the ratchet on the ratchet shaft can be rotated to adjust.

The fan wheel in the round sieve is equipped with two pig brown brushes, which push the fine powder out of the silk sieve and clean the mesh of the silk sieve in time. When the brush cannot brush the silk screen, loosen the bolt on the brush handle, and use the long hole on the brush handle to move the brush position so that it can brush the silk screen.

(2) Adjustment of disc wheat mill

①Feeding amount adjustment Adjust the feeding amount by changing the opening of the feeding hopper insert. The opening of the insert plate should be gradually opened with the increase of the number of grinding passes. When grinding for the first time, the plug board cannot be fully opened, and should be opened about 10-15 mm. Otherwise, the machine will be overloaded and the car will be stuffy, and it will also be easy to break the silk screen.

②Adjustment of grinding disc spacing Adjust the grinding disc spacing by turning the adjusting handwheel on the grinding disc clearance adjusting mechanism. The distance between the grinding discs is gradually reduced with the increase of the number of grinding passes. When adjusting, first loosen the lock nut, and then turn the adjusting handwheel. Turn the adjusting handwheel clockwise to reduce the disc spacing; turn it counterclockwise to increase it. After the disc spacing is adjusted, tighten the lock nut immediately to maintain the adjusted spacing.
