1, from the appearance of the identification of quality feed should be yellow, odor, delicate powder. Inferior feeds are yellow, black or gray in color and have coarse particles with astringent, bitter or odoriferous taste.
2, in the mixing of feed to identify high quality feed adhesive moderate, adjust the good feed into a group, soft, bulky, shiny and non-stick mixer. Inferior feed pellets are hard, easily broken or sticky, and are not easily removed from the blender.
3, in the feeding of identification of high-quality feed into the table after 1-2 minutes there are groups of squid to the table fight for food during the feed group is always scattered, there is no white turbidity flow. After the poor quality feed is put on the food table, the carp is lazy and it is reluctant to feed.
4. Analyze and analyze scientifically whether the quantity and proportion of its various nutrient components meet the nutritional standards of carp feed.
5, from the breeding effect of the identification of the general Japanese feed coefficient of 1.8, domestic materials (including Taiwan materials) for the 2.0 - 2.3, if the feed coefficient is greatly exceeded, it should increase the warning and identify the reasons.
Containerized Oxygen Generator
ETR can combine all parts of the oxygen generation system into a customized container, including air compressor, refrigerate air dryer, filters, buffer tanks and Oxygen Generator. Even the optional oxygen booster and cylinder filling station.
Compressed air is purified through the air dryer and filters to a certain level for main plant to work with. Air buffer is incorporated for smooth supply of compressed air thus to reduce fluctuation of compressed air source. The plant produces oxygen with PSA (pressure swing adsorption) technology, which is a time proven oxygen generation method. Oxygen of desired purity at 93%±3% is delivered to oxygen buffer tank for smooth supply of product gas. Oxygen in buffer tank is maintained at 4bar pressure.
