Building C21: R&D facility for plant cultivation
 

In Building C21, there are some multilayer-type and flat-type plant cultivation rooms that make it possible to conduct simulated cultivation experiments and research programs with a view to social implementation.

Built under a scheme called the “model-house demonstration, exhibition and research project” led by the Ministry of Agriculture, Forestry and Fisheries.

Leafy vegetables are produced experimentally in these rooms to demonstrate a high yield production with efficient light sources and air conditioners.
Nursery room Lettuce seedlings are produced at a low cost in optimized ways and conditions.
Precooling room Products are precooled and stored here before shipped.
Multilayer plant production room A Small-scale plant production (with a daily capacity to produce 250 heads) is conducted in this room equipped with fifteen-layer shelves employing Nutrient Film Technique (NFT) and an automatic picking robot.
Multilayer plant production room B The production laboratory equipped with an air conditioning system enables various experiments related to plant production using the two-story ceiling space.

Building C22: R&D facility for plant mass production
(The new-generation plant factory)


 Building C22 is a model facility as an artificial light-type mega plant factory capable of mass-producing up to 6,000 heads of two types of leaf lettuces (Frill lettuce and Batavia lettuce) combined per day. Here, various experimental researches from production, distribution through sales are conducted with an eye to realizing the social implementation of artificial light-type plant factories.

Built under a scheme called the “Innovation base location promotion project” led by the Ministry of Economy, Trade and Industry.
Structure: two-story steel frame
Total floor area: approximately 1,300 ㎡
Total project cost: approximately 700 million yen
(Construction cost: approximately 300 million yen,
Equipment cost: approximately 400 million yen)

Seedling transplantation and Nursery room scenes

Although our seedling selection operation is currently suspended, the automatic transplanting system is an essential technology in any mega plant. The seedlings embedded into nursery panels (153 cells/panel) will be grown up into 5-8 gram seedlings on 15-layer shelves in about two weeks.

Cultivation room scenes

The seedlings planted in 32-cell cultivation panels will be grown up into 80-90 gram plants on the 16 to 18-layer shelves formed in six lanes in about 20 days. Those cultivation panels are moved by two pallets per day toward the harvest room by the automatic transport devices.

■Construction purposes

Resolve social issues and meet industrialization needs
1 . Make plant factories well-known and widespread to help industrialize indoor farming.
2 . Strengthen the supply system to deliver “delicious”, “safe”, and “fresh” vegetables grown in plant factories to consumers.
3 . Make new social and local contributions to the field of agriculture through a demonstrative model project based on the industry-academia-government partnership.
4 . Respond to overseas demand for farming crops in uncultivable land areas such as a desert or cold region.
 

 

Introduction of state-of-the-art technologie

As the new-generation mega plant factory, cutting-edge technologies have been employed at each stage: such as a seedling selection system and an automatic transplanting robot, both following a circadian rhythm attributable to clock gene;automatic transport devices intended to release workers from heavy labor and curb labor costs; a direct air distribution system to each cultivation shelf; and a hybrid LED lighting system consisting of red, blue, white, and far-red lights. Those LED lights have been gradually replaced with white light LEDs, however, as technology progresses.

Production process in the-new generation plant factory
Product Name: Frill Lettuce / Batavia Lettuce
Daily production: up to 6,000 heads  

Starting with the seeding / germinating process, the cultivation flow goes through the nursing, cultivation and harvesting processes, before the trimming / packaging process. The entire operation takes approximately 40 days, about half the period of conventional production.

Minamihanada Lab. (OSP&PFC Second R&D Center)
– a model research institute for on-demand plant factories: Opened in October 2019
 

As artificial light-type mega plant factories are opening a new chapter in agriculture history, this laboratory is aimed at becoming an on-demand model research facility for studying and verifying mass production methods to cope with emerging demands for high-mix, high-volume or rapid-growth production of vegetables. This facility has been converted from an SC built earthquake-resistant warehouse and has three stories with each floor area of about 1,640 square meters. The building includes a would-be food supermarket on the first floor, the working area on the second floor and on the third floor located is Minamihanada Lab.(OSP&PFC Second R&D center).
