Shanghai Longyu expands automated food production equipment lineup

Shanghai Longyu Electro-Mechanic Technology Co., Ltd. is broadening its food machinery portfolio as demand rises for automated systems that can improve consistency and throughput across filled foods, pastries, and bakery products. The Shanghai-based manufacturer is highlighting encrusting machines and integrated production lines for domestic and international buyers.

Why it matters: - Food manufacturers are under pressure to automate production while handling more product varieties, fillings, shapes, and sizes. - Shanghai Longyu Electro-Mechanic Technology Co., Ltd. is positioning its equipment portfolio to serve bakeries, food factories, commercial kitchens, and other processors that need flexible, repeatable output. - The company’s machines are designed to support both standalone production steps and coordinated manufacturing lines.

What happened: - Shanghai Longyu Electro-Mechanic Technology Co., Ltd. highlighted its role as an Encrusting Machine manufacturer with a broad lineup for filled foods, bakery products, pastries, and other processed foods. - The company’s publicly listed products include multifunctional Encrusting Machines, Mochi Machines, Bread Machines, Cookie Machines, Maamoul Production Lines, Mochi Ice Cream Machines, Meat Ball Machines, Flaky Pastry Production Lines, Steamed Bun Production Lines, and Croissant Machines. - The company is based in Shanghai, China, and operates from No. 66, Jiushu Road, Jiuting Town, Songjiang District, Shanghai, China. - Public business information also lists the address as No. 66, Guangfulin East Road, Zhongshan Subdistrict, Songjiang District, Shanghai, China.

The details: - Encrusting machines automatically form products that combine an outer layer with a filling. - The technology can be used for moon cakes, mochi, filled cookies, stuffed buns, pies, filled dough products, and other specialty foods. - The publicly listed SV-208 Encrusting Machine handles products weighing about 10 to 275 grams. - The SV-208 supports adjustable shapes including round, cone, strip, square, and other configurations. - The machine uses a PLC and touch-screen control system. - Published output is about 60 to 99 pieces per minute, depending on the product and operating conditions. - Food-contact parts use food-grade materials. - A double-filling feeder is available for additional product configurations. - Longyu’s application list includes Chinese moon cakes, Japanese-style mochi, mochi ice cream, filled doughnuts, stuffed buns, pies, filled hamburgers, bread sticks, and soft-filled cookies. - The company offers Dough-Based Food Production Lines for broader manufacturing workflows. - Those lines can connect dough preparation, forming, filling, shaping, stamping, arranging, baking, and packaging. - Longyu also lists Flaky Pastry Production Line and Croissant Machine among its main products. - The company’s Maamoul Production Line includes an SV-208 Encrusting Machine, SV-303 Stamping Machine, and SV-302 Arranging Machine. - That line is designed for Maamoul and Chinese moon cakes, and also covers mochi, soft-filled cookies, pies, stuffed buns, sesame balls, and other products. - Public company information identifies Shanghai Longyu as an ISO 9001-certified manufacturer. - The company states that its machinery has CE certification. - Longyu also says it holds patents related to its encrusting machine cutter technology. - The company’s manufacturing base is in Songjiang District, Shanghai. - Public supplier information describes Longyu as a manufacturer and exporter with customers or markets in Europe, North America, Asia, the Middle East, and Latin America. - The company’s official website is More information.

Between the lines: - The product mix shows how one forming technology can support both traditional regional foods and more standardized bakery products. - Integrated lines matter because larger producers often want fewer manual steps and more consistent output across longer runs. - PLC and touch-screen controls point to a shift in operator work from manual forming toward setup, monitoring, sanitation, and quality checks. - The company’s focus on adjustable size, shape, and filling ratio reflects a market that wants faster recipe changes and more format flexibility. - Certification and export claims matter, but buyers still need to confirm documentation, compliance needs, and service coverage for each specific machine and destination market.

What's next: - Food manufacturers evaluating new machinery will likely continue testing equipment with actual dough and filling before buying. - Buyers will look at product formulation, filling type, target weight, shape, speed, factory space, and automation level when choosing equipment. - Longyu’s broader opportunity is to serve both smaller businesses that need a single machine and larger manufacturers that need full production lines. - Continued demand for moon cakes, Maamoul, mochi, filled cookies, stuffed buns, and pastries could keep automated forming and filling equipment in demand.

The bottom line: - Shanghai Longyu is betting that flexibility is now as important as speed in food manufacturing, and it is packaging that idea in standalone encrusting machines and integrated production lines.
