Embodiment
[0048] Adopt the PP-R produced by Borealis Company, model Borclear RB709CF, add the commonly used antioxidant Ciba-Geigy Company's production model Irganox B225 in the plastic processing industry, add 1500ppm. In order to increase the weather resistance of the PP-R plastic film tube, an additional UV absorber Eversorb 73 from Taiwan Everlight Chemical Co., Ltd. was added in an amount of 0.6% by weight. After mixing evenly, use a general plastic film blowing machine with an operating temperature of 220°C to 250°C. The thickness of the blown film is controlled at 0.12 mm, and the width of the plastic film is controlled at 19 inches. After blowing, no processing procedures are required. , directly wound into bundles for later use. After the processed plastic film tube is injected with water to start cultivating algae, it will be stretched by water pressure to form a cylindrical culture tube with a diameter of 30 cm.

Abstract
The invention discloses an improved tubular enclosed algae culture system, which is characterized in that: a glass tube or a transparent polycarbonate (PC) tube of the traditional tubular culture system is replaced by a film made of a high-light transmission polypropylene (PP) material through a plastic film blowing machine, so that the hardware investment cost of the traditional tubular culture can be greatly reduced, and the high yield of the enclosed algae culture system is kept. Due to the film culture system, the dry weight yield of algae cells is 1.13 times that of the transparent PC tube culture system, and the cost of tubes in the culture system is greatly reduced to be about 0.36 percent of the PC tube culture system; therefore, the large-scale enclosed algae culture has commercial feasibility. The algae culture system can be used for culturing high-oil content micro algae to produce grease serving as a raw material for producing biodiesel.
Description
technical field [0001] The present invention relates to a new algae culture system, which mainly uses a thermoplastic with high light transmittance, especially polypropylene resin, to process it into a tubular film to replace the traditional expensive and hard-to-process hard culture pipe. Background technique [0002] The commercialization of algae cultivation is not a new field. Chlorella and spirulina cultivation in Taiwan have been used as healthy food ingredients for more than 30 years. In the past, almost all algae culture factories used an open culture method (Open Ponds, Race-way system). The open culture method is relatively extensive, and various parameters of algae growth (such as CO 2 , nutrients, environmental climate, etc.) can not be effectively controlled, it is easy to cause the algae to be polluted by bacteria, the risk of algae cultivation is high, the space requirement is large, and the final concentration of algae cell culture is low, which also leads t...
