The introduction of the modern clean room facility was a key development in Dacun Farm, as well as a breakthrough in the production of food/drug mushrooms in Taiwan. In the production process of mushrooms, the initial process runs from medium selection, fermentation, nutrition mixing, filling, to sterilization in 130°C high temperature. Following the initial preparation, the pouches are then sent into the clean room for inoculum and cultivation. The clean room facility is like the hand of God. It controls the air, temperature, humidity, and light in a consistent and optimal state for the mushrooms. Therefore, the mushrooms grow with high degree of stability and vibrant life. And because of the consistent environmental criteria, production of mushrooms is now controlled as an industrialized "plant factory", where products are manufactured with unified specifications and stable quality. The farm is also engagied in the development of several popular species, including Eryngii, ostreatus, lingzhi, golden mushroom, and the Yunnan series Eryngii.
