Case Study: Yamachan Noodles

100% Inspection for Yamachan Noodles

Case Study: Something to Noodle on

Profits Increased in Multiple Areas of the Assembly Line for Food Manufacturer, Yamachan


Yamachan – the “Ramen noodle for your needs” – produces various high quality, authentic Japanese Noodles for restaurants across the country. The company manufactures customized noodles based on request and the needs of the restaurants it serves using Japanese-made machines and techniques. They also produce varieties of retail products including mild, rich, and no MSG noodle packages. 


With restaurants as its primary business base, Yamachan wanted to ensure they were providing the same portion sizes in each package of noodles to maximize cost efficiencies for its customers. In addition, as a food manufacturer, the company is held to high standard for product contaminants, and wanted to make sure each package was free of metal fragments. 


Product managers at A&D Inspection recommended installation of the AD-4971-3517 metal detector, the AD-4961-6k-3050 checkweigher with rejector for over- or under-weight products on the assembly line, and the ProteX X-ray inspection system as part of the production process and after the packing process.  This combination ensures 100% Product Inspection for Yamachan.

Portioned Noodles

Noodles are portioned prior to going through the bagger.
  After the product is bagged, it then travels through the metal detector and checkweigher.


Following implementation of the checkweigher and metal detector as part of the production process, improvements were immediately recognizable, and due to the easy programming and data analysis capabilities in the A&D Inspection equipment, immediately documentable audit trails and inspection history reports the following:  

  • Accurate measurement within 1g +/- repeatability
  • Accurate metal detection readings down to 1mm Ferrous
  • Worker efficiency improved with a reduction of rework
  • Quality assurance team trusts A&D with inspection of over 180,000 packages per month 

Most recently, Yamachan also installed the new ProteX X-ray system to augment their quality assurance efforts.  Watch the video below to see how X-ray inspection helps Yamachan detect foreign materials, including a variety of potential contaminants. 


Yamachan was so pleased with their results, Hirotaka Yamashita COO/ Director sat down with us for an interview.

Less downtime overall and easy to service the equipment”.  Worker efficiency - “(the) machine is very user friendly and once you set the products up you really don’t have to make adjustments.”  Quality assurance team - “Our team relies on the audit train function and A&D is developing a special yield rate firmware version for our needs.”
