Japanese plant Spread upgrade secret LED meritorious

According to the United Nations, the global population is expected to reach 10 billion in 2050, directly leading to food production is facing heavy pressure. In this case, more and more companies are starting to build vegetable plants, such as Singapore's farm towers or water farms. A recent case is from Spread, japan.

The 9 year old vegetable growing company plans to build a new plant of about $4400 a year in Kyoto to grow lettuce, which is expected to reach about $30 thousand a day. Compared to the earlier Spread plant, the new plant will introduce robots to automate the process.

Growing plant

In fact, the plant is not a new word. Because it can avoid the air, water and soil pollution, and control the growth environment of plants, in recent years, there have been a number of companies do plant. In such a poor indoor ventilation of the factory, the food is how to do?

Alternatives to sunlight, LED light

In the room, there is no sun how to do? The solution to the plant is a specially designed LED lamp.

Compared with the traditional lighting technology, LED lamp has obvious advantages: high light efficiency, low energy consumption, bulb temperature and therefore at a low level, the cost is also cheaper than the agricultural greenhouses commonly used high-pressure sodium lamp 1/4.

Specializes in agricultural lighting PHILPS and general electric are doing this special LED lights. For example, Mirai company is used to do the general electric LED lights, light through the leaves to allow the whole plant to get light, the speed of the vegetables are also raised to 2.5 times the outdoor planting. The PHILPS LED lights can be set according to the different spectral frequency, which is called the "Recipe" (Light), to affect the growth of plants.

There is no soil, with recycled water

Hydroponic plants need less water, water recycling, these two are the main water-saving measures plant.

As with other plants, Spread plant is using hydroponic methods to grow lettuce. Seeds were grown in a hydroponic environment rich in nitrogen and potassium. Compared to the outdoor cultivation of lettuce in the soil, Hydroponic Lettuce requires only 1% of water, the required nutrients only 1/4.

As for the water recycling system, Spread's new plant is expected to be able to recycle 98% of the water during the plant, mainly to recycle those from the plant leaves into the air moisture. The process of water resources recycling will generally use dehumidifier.

Plants also blowing air conditioning

In addition to being able to provide heat LED lights, Spread new plant will also be used to adjust the temperature of a special air-conditioning. The combination of air conditioning and LED, compared to the previous plant, the cost of each lettuce reduced by 30%.

In addition, Spread company in order to keep the plant in the process of planting no pest and disease free state, but also requires employees to wear special costumes, to prevent pollution of plants in the process of planting.

Automatic, no one to look after

In the new plant, Spread plans to give the process to the robot to complete, compared to the previous manual way, the automation process can save 50% of the cost.

The planting process currently has 6 parts, sowing, germination, seedling planting, bed to transport more vegetables cultivation mature, harvest and transport of vegetables to the packaging line, the robot has been able to complete 4, Spread company is in the process of planting machine development.

Since all planting conditions are controlled indoors, the indoor plant can provide a steady supply of vegetables to the market. At present, Spread for 2000 stores to provide vegetables, the price is not different from the outdoor planting lettuce, Spread said the same taste.
