Meeting the various needs of food factories

Flow Line Planning, Zoning

Due to the wide variety of fresh foods produced, planning of a specific flow line for raw materials, products and people, and clear zoning for sanitary areas were designed. Furthermore, a system to prevent contamination from outside and to prevent the introduction of foreign substances was installed, achieving an environment which maintains thorough freshness and sanitary management.


Renewal of the existing factory and the additional construction of building were carried out while the factory was under 24 hour operations. Temporary work was planned and carried out to prevent dust from entering into the existing factory. Furthermore, low-odor materials were used. Construction was planned and carried out in a way that operations of the existing factory would be affected as little as possible.

Factory Relocation

Relocation of existing factory to adjacent to existing factory at another site was planned. Multiple-layer type building, which is uncommon for food factories, was adopted to make good use of the land. Furthermore, consistency in sanitary zoning and material flow, as well as countermeasures to waterproof properties and dew condensation were taken into consideration. As a result, an industry leading factory with high-productivity was achieved.

Overseas Advance

The factory produces seasonings targeting people in overseas and is considered to be the largest base in the overseas food business. The factory contributes to increasing the company image among local customers not only by manufacturing safe products, but also by inviting visitors to view the facility.

Open Factory

The factory was highly evaluated for its HACCP compliance and high technology for cold region in a competition. The factory integrates the most advanced production line which meets HACCP and ISO14001 requirements with an enriched visitor facility to introduce the client's brand, and promote the safety and performance of its products.

Energy Saving

Engineering techniques which perceive building and production equipment as one unit were introduced. Heat emitted from the production equipment (firing room) was analyzed by air flow simulation, and a "Natural Ventilation System" which discharges the heat using natural forces was adopted in order to save energy.

Hardware Countermeasures
Sanitary Countermeasures for the Building

  • Determining contaminated and uncontaminated areas
  • Flow line planning for people and goods based on contamination prevention
  • Interior planning for individual rooms
      (floor, wall, ceiling, door, etc.)
  • Environmental requirements for individual rooms
     (temperature and humidity, illuminance, sanitation)

Sanitary Countermeasures for Manufacturing Machines

  • Review on cleaning and anti-bacterial prevention of the equipment
     (quality of material, finishing, accessories)
  • Design of a monitoring system corresponding to critical control points
  • Prevention of cross-contamination between machines
  • Securing sufficient work space

Software Countermeasures
Maintenance of the Building

  • Cleaning of the Building
  • Cleaning and sterilization of equipment and machinery
  • Maintenance of the building, equipment, and machinery
  • Environment measurement of production room
      (floating bacteria, falling bacteria)

Sanitation Control for the Workers

  • Management of hand washing and disinfection
  • Management of clothing, footwear, etc.
  • Health control for the workers
  • Hygiene education for the workers

Developing a sanitation plan in compliance with HACCP, based on Abundant Experience in Food Factory Construction

Realization of a production environment with high-sanitation by establishing countermeasures to insects, rats, bacteria, and mold.

Planning the most appropriate work area and flow line in compliance with HACCP, based on the production process of each client

By zoning contaminated, semi-sanitized and sanitized areas, invasion of foreign substances will be prevented. Cross contamination will be prevented by separating people flow line from goods' one.

Flow Line of Goods and Barriers (example: Dairy Dish Factory)

Contamination by powder dust from goods and pieces of paper is prevented by barriers.

Flow Line of People and Barriers (example: Dairy Dish Factory)

Invasion of human hair, bacteria, and dust attached to clothing or shoes is prevented by barriers such as changing clothes and shoes, hand washing sterilization.

Safety of the manufacturing environment is improved by emphasizing insect, rat, bacteria, and mold countermeasures based on our years of abundant experience of the food factory.

Insect and Rat Countermeasures

Countermeasures, which is reliable and friendly to environment, are established by three systematic policies and methods using minimal amounts of pesticide.

No Attractant

  • Selection of wood types that insect dislike
  • Insect repelling illumination
  • Insect repelling window film
  • Berm, pavement, and curb around the building

No Entry

  • Cutout of invasion route
     (Several traps, such as insect repelling trenched, etc.)
  • Restricted Entrance
  • Double protected entrance
     (Airlock, air shower)
  • Airtight around perimeter
     (Dock shelter, sealing at interstices)
  • RShortened period for opening and closing
     (high-speed sheet shutter)

No Increase (Catch)

  • Insect catcher (for capturing, for monitoring)

Bacteria and Mold Countermeasures

Countermeasures based on the four principles for anti-bacteria and anti-mold are established in the hardware and software fields.

Invasion Countermeasures

  • To plan the entrance preparation room
  • One way toilet

Countermeasures to Prevent Occurrence or Spread

  • Consideration to the floor
     (Crack prevention, aridification, floor slope)
  • Sanitation
     (Finishing, round finish of reentrant section, Stainless steel trench, Stainless steel pit)
  • Dew condensation prevention
     (High heat insulation, ventilation to prevent stagnation, effective exhaust equipment)
  • Sterilization lamp
  • Pressure control among areas

Elimination Countermeasures

  • Sanitation (Finishing, round finish at reentrant section, Stainless steel trench, Stainless steel pit)
  • RPlan of a dedicated equipment washing room


Performance can be improved through renewal aiming at better efficiency of factory, reviewing the production base, and using the most advanced systems, such as In-factory Logistics System and Manufacturing Execution Management System.
