The rice milling machine is a grain processing machine that processes rice into rice in China's rice producing areas. China's rice processing rice accounts for about 30% of the total commercial flow of general grain processing by rice processing plants using large-scale rice milling machines for complete sets of equipment, accounting for 70% of the total amount of rural farmers' food used by processing professionals and farmers' families. Small-scale rice milling machine processing; especially in recent years, the small-scale rice milling machine widely used in rural areas has developed rapidly; it solves the problem that the rural labor force picks up grain processing after entering the city for work, lacks human resources, and brings life to thousands of families. Convenient.
In addition to the size of the product, the rice mill is divided into iron roller, sand roller, iron roller and air jet, and separate rice mill. In addition to the sand roller is a complete set of equipment, raw materials need to use brown rice as raw materials, and other imported materials can be processed directly from rice. At present, there are more than 120 rice mill manufacturers in China, among which small production There are about 110 agricultural rice milling machines with an annual output of more than 1.1 million units. Most of the small rice milling machine enterprises in China are private enterprises. Most of them are small in scale, weak in technical strength, poor in production conditions, and difficult to guarantee product quality. In recent years, the sampling rate of national and local provincial supervision and sampling products is generally around 70%. Users have a strong response to product quality.
At present, the main problems in the quality of rice milling machine products are: product safety facilities are not perfect, the instructions for use do not meet the requirements, can not effectively prompt the operator to avoid danger, the operator's physical injury incidents occur; the quality of manufacturing, the quality of purchased parts The assembly quality, welding quality and appearance quality are poor, resulting in high energy consumption, high noise, more broken rice, low equivalent rice output rate and short service life.
In order to help users choose and use the rice milling machine to avoid losses caused by improper purchase, users should pay attention to the following issues during purchase and use:
First, determine the size of the model as needed.
The purchase machine should be based on the requirements of use, the scope of application and local power supply conditions, and according to the processing output, how large and what type of machine, such as three-phase power supply, the general processing output is more than 200 kg per hour, single-phase power supply for agricultural use. Small rice mills generally produce about 100 kilograms per hour. There are two types of agricultural small rice milling machines on the market; one has a separating device, and the rice is separated by a separating device to remove the bracts and the mouth of the valley to meet the food standard requirements. The other is that without the separation device, the processed rice needs to be removed by another separating machine (or windmill) to remove the bracts and the valley mouth in the rice. This kind of machine is suitable for use in some remote rural areas where the voltage is unstable and the power is insufficient. It is better to purchase a rice machine with a separating device when the power supply is stable and sufficient, so that it is convenient and quick to use.
Second, check the random data to verify the product "identity"
When purchasing a rice milling machine, you must first check the relevant information that can prove the product. First, check whether the product has a factory certificate, “three guarantees†certificate, product identification certificate, and implementation standards; whether it is qualified in the recent quality supervision and spot check. "Three no" products, certificates and unqualified products can not be purchased.
Third, put a good quality inspection
After verifying the relevant information of the product, it is necessary to further check the quality of the product. First, it is necessary to look at the exposed tape wheel, whether there is any protective device on the running part of the tape; the protective device must have a certain anti-extrusion strength. There are no hazard warning signs and instructions on the machine. There are no requirements for operation and maintenance safety precautions. This is the requirement that the safety quality should be achieved. Secondly, the main shaft pulley is rotated by hand to see if the main shaft and the fan are stuck when turning. Whether it is flexible; look at the quality of assembly and welding appearance;
Fourth, understand the instruction manual, use it correctly
Before using the rice milling machine, read the instruction manual of the machine in detail, and perform the debugging operation according to the requirements of the instruction manual. Pay special attention to the safety precautions in the instruction manual and the safety warning signs on the machine; prevent safety accidents; The raw materials of rice should prevent the incorporation of stones, magnetic substances and other impurities, so as to avoid damage to the machine. Grease should be added regularly to the bearing; after cleaning, it should be cleaned and maintained to extend the service life of the machine.
