After the acquisition of rice, can not be eaten directly to users. It must go through this procedure will hulling paddy husk off, made of brown rice, and then through this procedure will be made of rice brown rice can give users edible. So Paddy Husker(LIANGGONG) processing is very important to a process.

Rubber roller husker is hulling machines currently commonly used, the gap two rubber rollers rubber roller hulling machine directly affects hulling quality, resulting in a gap too large can not shelling, the gap is too small would cause broken, and after prolonged use rubber roller, a gap will change due to wear caused by decreased mass husking, so the hulling machine is generally provided with roller adjustment means to adjust the two roller gap, but the commonly used rubber roller hulling machine currently in use adjusting screws to adjust the two roller gap which is adjusted two rubber nip with the operator's experience, there is clearance adjustment is not timely, accurate and resulting mill Valley is not complete or problems of broken rice.

After removing roller rice husk, chaff into the separator separates and brown rice husk, but the adjusting plate in a wind chaff separator currently used fixed on chaff separator can not be adjusted according to actual needs, so there is the problem of incomplete separation of the chaff, when the loss of working time is incorrect, resulting in unnecessary waste. Currently used hulling machine hulling rice into the flow into the nose is to rely on a pull-out door on the hopper to control, not to precisely control the flow into the rice hulling machine head according to the actual processing speed, this will cause sometimes rice caused by too much traffic into the hulling of poor quality or stuck hulling machine.

The most outer rough shell of paddy is removed. Paddy Separator(LIANGGONG) is the most common machine that is used for paddy shelling, however friction type browner is sometimes used as a sheller. Paddy goes between six rubber rollers that are rotating in opposite direction with different velocities. There is a small clearance between the rollers so that when paddy passes through, it is subjected to some shear forces and husk is removed from production process of rice peeled.

Design of experiments ( DOE) and Response Surface Methodology (RSM) is a collection of statistical and mathematical techniques useful for developing, improving and optimizing process and new products, as well as in the improvement of existing product designs. RSM can take unknown response function and approximate it by coded variables where these coded variables are usually defined to be dimensionless with zero mean and the same spread or standard deviation. Usually a low order polynomial in some relatively small region of the independent variable space is generated. The example presented above demonstrates that designs taken from the RSM paradigm can be used to good effect in a traditional agricultural setting and this point is further underscored by the work. And according to Hill and Hunter, RSM method was introduced by G.E.P. Box and K.B. Wilson in 1951. Box and Wilson suggested to use a first-degree polynomial model to approximate the response variable. They acknowledged that this model is only an approximation, not accurate, but such a model is easy to estimate and apply, even when little is known about the process. The resulti ng surfaces, usually linear or quadratic, are fitted to these points.

Often statistical methods such as design of experiments are used to determine where in the design space these points s hould be located in order to obtain best possible fit. In this paper we use linear polynomials to create the response surface. The creation of such response surface models to approximate detailed computer analysis codes is particularly appropriate in the preliminary design stages when comprehensive trade-offs of multiple performance and economic objectives is critical. In many cases, either a second-order model is used.

Small Paddy Husker(LIANGGONG) by many families of all ages with its simple, inexpensive features.How do we buy paddy husker should be adjusted and maintained it?

1.The adjustment of rice knife

Adjust the rice knife is to adjust the gap between rice knife and drum. If the gap is large, the grinding chamber pressure is small, the rice in the drum by the friction of the weak, so the meter can not grind fine, but a high rate of rice.

2.The import and export of knife adjustment

When the knife of import and export knife off hours, crush room grain increased, the pressure increase milled white and beige, but the broken rice; conversely, if the import knife off the export knife open, whitening room save less meters, the pressure is reduced, grind rice is rough.

3.The specific operation and adjustment measures

(1) A rice cutter and roller to adjust the clearance to moderate, clearance is generally not less than a grain of rice the transverse diameter. Otherwise, grain can be easily broken; gap can not be larger than a grain of rice the longitudinal diameter or coarse grain of rice. Therefore, rice knife gap should be to choose between vertical and horizontal diameter of rice. Generally in the adjustment of the actual knife meter gap, there must be a angle, that is, near the outlet switch is slightly larger, such a grind rice is more complete.

(2) The import and export of the knife to work closely with each other. The general import knife opening control in the opening of the 1/2, no more than 2/3. In rice milling process, generally do not will import knife removed, let the import of all open, because open all imported knife after cereals accumulated too much, grinding chamber pressure is too high, rotational resistance, if export knife temporarily do not match up well, belt drive will slip, even to the machine will be stuck or damaged.

4.Maintenance matters

(1) Milling machining of rice, to maintain a certain degree of drying, the moisture content is generally not more than 14% -15%. When the high moisture content of rice, broken rice, affect the quality of the rice, but also with the increase of power consumption.

(2) To pay attention to check whether there are nails in rice, stones and other debris, so as not to enter the white room to cause clogging or damaged rice sieve.

(3) Before starting with rice sieve, a rice cutter, drum core parts to check to see whether to tighten the bolts and nuts.

(4) Before starting the drum to see if there are four.

(5) The boot when the first empty load operation to normal speed, and then poured into the rice hopper, and keep the rice milling machine operation.

(6) Every day after work, the paddy husker machine and ancillary facilities were a check, found problems in a timely manner, to ensure paddy husker machine often in good condition.

The rice is passed through a number of different operations and machines from paddy to white rice is called multistage milling process. Removal of husk layer from the paddy by friction process is called de-husking (or) dehulling. The different types of Rice Huller(LIANGGONG) machines are steel huller, under runner disc sheller and rubber roll sheller. The steel huller and under runner disc sheller have very low milling efficiency and hulling efficiency . Economic values of the grains based upon yield of the grain and percentage of head rice yield.

The objective of rice milling system is to remove the husk and the bran layer to produce white rice. Rice milling can be undertaken at three levels. When the husk and bran layer is removed in one process and the white rice is directly produced from the paddy, it is called one step milling process. The husk and the bran layer is removed separately and the brown rice is produced as an intermediate product, it is called two step milling process.

The parameters that affect the rice breakage and rubber roll wear depends on the type of harvesting, drying temperature, drying methods, physical characteristics of paddy, husking characteristics, paddy moisture content, rubber roller speed, rubber roll pressure, paddy feed rate, fissures and rubber roll wear. So for polyurethane and food Quality Nitrile rubber compound has been developed to test the shelling efficiency and rice breakage. Fresh paddy contains 28% of moisture content and this leads to increase in rice breakage during rice milling. Temperature adopted for drying should be altered based on the level of moisture content. Each paddy has different kernel dimension and it leads to rice breakage during the husking operations.

Rice breakage depends on husking ratio, husking time and husking index. The optimum moisture content in rice milling is 12-14% w.b, rice breakage is low at this moisture content. Higher roller speed leads to increase in rice breakage and in turn roller operated at lower speed leads to unhusked rice. So the optimum roller speed for husking operation in rice milling is 2.9 m/s. Rice breakage is also based on the feed rate in the rubber roll huller. In friction process, crack is developed in the rice kernel and it leads to rice breakage. Rubber roll material wears due to the friction process of paddy de-husking. Rice breakage is also varied based on rubber roll hardness.
