A system and a method for performing an automated winterization process for a swimming pool or spa are provided. A temperature sensor collects a sensed temperature value, which is transmitted and processed by a control system of a connected aquatic system. Based on the sensed temperature value, the swimming pool or spa control system executes the automated winterization process for the swimming pool or spa. The automated winterization process includes displacing water with air using an air-moving device in a first loop path and a second loop path using one or more actuated automatic valves.

The present application relates to the field of microbial technology, and particularly relates to a kind of schizochytrium sp. producing high content, high clarity oil and application thereof. A schizochytrium strain with high quality after winterization is found in the screening process of schizochytrium, and the DHA content of the oil produced by fermentation is much higher than that of other strains. The schizochytrium provided by the present application is particularly suitable for preparing winterization products. After winterization treatment, a considerable amount of DHA is preserved in soft fat, and the quality of the winterization oil product is high, with high economic value.

The present application relates to the field of medicine manufacturing, and relates to a preparation method of natural source cholesterols for injection, which comprises the following steps: taking fish oil, cooling and winterizing, taking the lower sediment, heating to dissolve it into clear winterization fraction, adding the winterization fraction into a chromatographic column filled with mixed filler of adsorbent and filter aid which are mixed uniformly in a physical way to perform circulation chromatography, emptying the winterization fraction after the circulation ends, adding eluent to the chromatographic column, and recovering the solvent after the eluent is combined to obtain cholesterols concentrate. The cholesterols concentrate is added with first crystallization solvent to recrystallize and refine twice, the cholesterols crude product after recrystallization is taken and added with second crystallization solvent to recrystallize and refine, and the product is dried under reduced pressure to obtain cholesterols for injection. The present application solves the technical problem of preparing cholesterols for injection from fish oil, is suitable for large-scale industrialization of cholesterols, can be applied to preparation of complex preparations such as liposomes, and improves the safety of drug use.

The invention relates to the field of fish oil filtering, in particular to a fish oil winterization filtering device which comprises a tank body, a feeding pipe is installed at the top of the tank body, the bottom of the tank body is in an arc shape, a stirring driving cylinder is fixedly installed in the middle of the tank body in a penetrating mode, and a discharging pipe is installed on the side face of the stirring driving cylinder in a penetrating mode.

The scraping plate stirring mechanism slowly rotates in the tank body to stir fish oil, the fish oil is prevented from being attached to the inner wall of the tank body, the filter screen cylinder can intermittently move downwards for filtering for multiple times, liquid oil is extracted, and the liquid oil in the fish oil is fully extracted.

The application provides a method for efficiently separating solid grease from polyunsaturated fatty acid oil, which comprises adding a certain amount of inert substances into the polyunsaturated fatty acid oil, cooling and crystallizing, and then filtering through a filter to obtain clear polyunsaturated fatty acid oil, and then passing hot gas into the filter to dissolve the solid grease adsorbed on the filter cake and recover the solid grease through the filter plate, and the inert solid substances can be reused next time. Through the method, saturated and low-saturated fatty acid solid grease can be efficiently separated from the polyunsaturated fatty acid oil, the winterization crystallization time in the process is short, the crystallization is complete, the crystal separation is easy, and the phenomenon that part of the solid grease melts and reenters the filtrate due to long separation and drying time in the conventional process does not occur, so that the yield of the final product is as high as 89.8%-97.8%, and the polyunsaturated fatty acid oil after winterization treatment is clear, and no crystal is precipitated at 0 DEG C for 5 hours.

Water drainage system for a pool covered with a tarpaulin, characterized by that the cover (3) has at least one drainage opening through which the water collected on the cover is conveyed via a pipe (10, 11) to an existing inlet or outlet opening (4, 5) of the pool, the water is drained out of the pool above the cover.

The invention discloses direct drinking tea seed oil and a preparation process thereof, and relates to the technical field of grease processing. The method adopts a pure physical squeezing and whole-course low-temperature treatment technology, and comprises the following steps: screening fresh tea seeds, performing low-temperature drying treatment, and performing mechanical shelling and crushing to obtain a tea seed kernel and tea seed shell composite squeezed material in a specific proportion; and finally, obtaining virgin grease by adopting a low-temperature physical spiral squeezing process. The obtained crude oil is sequentially subjected to rough filtration, sedimentation and vacuum suction filtration, and then is subjected to the steps of ultrasonic-assisted hydration degumming, low-temperature winterization wax removal, vacuum low-temperature drying and the like, so that non-triglyceride components such as impurities, moisture, phospholipid and waxiness in the grease are effectively removed.
