Polypropylene steamer, which is made from the local unique Luozhu as the main raw material, has been processed by hand. It has the characteristics of natural, green and environmental protection. It uses steamed food in the “steamed steamer” to preserve the original taste of the food. It accumulates distilled water, is not easy to change, and is resistant to heat preservation. It also makes the food leave a unique fragrance of Luozhu, which is favored by consumers at home and abroad.

Quality characteristics Polypropylene steamer is one of the important traditional products of Luoding City. “Jianlun Steamer” is made from the unique local Luozhu as the main raw material. It is processed by hand process and has the characteristics of natural, green and environmental protection. The steamed food of the glutinous rice steamer not only retains the original flavor of the food, but also does not accumulate distilled water, is not easy to change, and is resistant to heat preservation. In the mid-1990s, the technological content of steamer processing continued to increase. Most of the processes that were originally hand-operated have been semi-mechanized. The sawing bamboo, the opening, the nailing, and the steel ring are all used in the machine, so that the output of the steamer is increasing continuously and the quality is continuously improved. Polypropylene steamer is available in a full range of sizes, including a 4-inch point cage, a 6.5-inch steamer, a 20.5-inch bamboo cage, a 6.5-inch steel woven bottom cage, a steel-bottomed bamboo bottom cage, an aluminum-woven bottom high cage, and a new steel. A total of 40 specifications are available for the bamboo base cage. Production conditions Luoding is a semi-hilly mountainous area with many fertile mountains and annual rainfall of about 1400 mm. In the mountainous areas of Luneng, Dumen, Jiayi, Fuhe, Suibin, Xinle, etc., the mountains are dense and dense, the vegetation layer is thick, the mountains are in a humid state for a long time, and the special climate environment grows Sharozhu, also called Luo Zhu. Before the founding of the People's Republic in 1949, farmers had developed the habit of planting bamboo. After the 1970s, the planting area increased year by year and the scope continued to expand. After the reform and opening up, the demand for bamboo steamers in the market increased year by year. Farmers saw the prospect of processing bamboo steamers, so they actively developed Luozhu production. In 1979, there were 7200 mu of Luozhu, which grew to 8400 mu in 1989. In 1999, it increased to 13,000 mu, and in 2003 it reached 38,000 mu. More than 23,000 acres of eucalyptus are planted. Luozhu planting is generally harvested in 4 years, and can be harvested once a year. The harvesting time is from winter to spring of the next year. The yield per mu is generally 6000-7000 kg, and the high yield can reach 10,000 kg. There are many people in Luoding, less cultivated land, and less cultivated land in mountainous areas. In 2003, the town of Yanlun Town was 73,917, with more than 32,241 laborers. The cultivated land was only 30,374 mu, with an average of 0.41 mu per person. The abundant labor resources have created favorable conditions for planting Luozhu, processing steamers and increasing income. Historical origins The production of the Polyester steamer originated in the years from 1796 to 1820 (Qing Dynasty Jiaqing), with a long history. Before the founding of the People's Republic in 1949, some farmers had processed Luozhu into steamers and bought them in the market, and some even took them to Zhaoqing and Guangzhou for export. Luoding steamer has a certain reputation outside. After the founding of the People's Republic of China, mountain farmers used processing steamers as a sideline income. Many farmers not only know how to process steamers in adult men and women, but even children aged six or seven know how to process steamers. In the early 1970s, bamboo and bamboo processing plants were built in the areas of Polyester and Suibin, and bamboo rafts were also produced to process steamers. Some steamers are sold in the market, some are supplied to county town restaurants and restaurants, and some are exported to foreign trade departments for export. After the reform and opening up, some advanced developed countries began to advocate environmental protection. They gradually realized that the use of bamboo steamers as cooking utensils is better than the cooking of metal products or plastic products as cookware, and the cost is low, pollution-free and beneficial to health. Order and use bamboo steamers. Bamboo steamers are favored by foreign friends, and there is a growing demand in the market. In the 1980s, the demand for steamers continued to increase, and the market was in short supply. The government and relevant departments took advantage of the situation and organized large-scale Luozhu, and the planting area of ​​Luozhu continued to increase. In the areas of Huanlun and Suibin, the processing steamer is used as an industry for farmers to generate income. In addition to the township steamer factory, the steamer raw materials are distributed to farmers for processing and regular recycling, which not only strengthens the development of the collective economy, but also increases the income of farmers. . After entering the 1990s, the individual economy continued to grow and develop, and steam cage production has new developments. In some places, professional streets, professional villages and processing and sales of processing steamers have been formed. And gradually explored a "company + base + farmers" steamer processing industrialization path, the implementation of "romatic bamboo planting - steamer processing - product sales" integrated operation, formed a Luozhu steamer, steamer to promote Luozhu A virtuous circle of development. Processing Technology There are several steps in the processing of steamer. One is to select the material, and select the high-quality Luozhu which is planted in the local deep mountain for more than 4 years, with bamboo straight, long diameter and nodules. The second is to open the material, cut the cut bamboo and remove the leaves, and cut the bamboo into various lengths according to the specifications of the steamer that needs to be processed, and break it open and cut it. The third is to cut the pieces, cut off the opened bamboo pieces to the surface of the bamboo green, and smooth the bamboo pieces, the size is even, and at the same time do the anti-corrosion and disinfection treatment. The fourth is the baking sheet. The sliced ​​bamboo pieces are baked on the fire to make it have good flexibility. According to the specifications, the baked bamboo pieces are bundled in several pieces, and the special wooden sticks are rolled into a circle. Shape, dried to be woven. The fifth is to shape the bamboo pieces, which are rolled into a round shape according to the specifications of the steamer. The copper wire is fixed and fixed to make the outer ring of the steamer. Four pieces are used on the inside of the outer ring, and two pieces of bamboo are rolled into a circular shape to support the outer ring. This process is called a top bamboo. Then enter the sub-port process, the material of the sub-port is various, there are bamboo, wood, copper, steel, etc., can be selected according to customer requirements. Then pierce the cage, put the bamboo nails, and then enter the cage bridge (the bottom of the steamer supporting the food). When entering the bridge, the cut bamboo strips are arranged in a row, wrapped and fixed with white skin rattan. The sixth is to carry out insect control and drying on the woven steamer. Seventh, the dried steamer is polished, and the side hair is removed to form a steamer.
