Cats eat fish, foxes also eat fish! Medium and small sea miscellaneous fish can be fox's main feed. The amino acid content of fish is similar to that of warm-blooded animals and can be used as the main animal feed for fox (especially the Arctic fox), and is cheaper. However, it should be noted that such by-products as fish heads, fish rafts and fins must have low levels of amino acids, can be fed in small amounts, and can only account for 10%-15% of animal feed protein, and must be guaranteed for other full-priced feeds. supply. Otherwise it will have serious consequences. According to the physiological characteristics of fur animals, special premixes for special Chinese and Western cultures have significantly improved scientifically designed and formulated feeds, digestibility and utilization rates.
Fish is an important source of vitamins A, D, B12 and calcium, phosphorus, cobalt, iodine content is also very rich, but less iron, copper, manganese, zinc content. Sea fish that do not go visceral can account for 30% of the total amount of feed and can guarantee the general needs of vitamins A, D and B12. When feeding fish, be aware that the carp is a form that cannot be digested and absorbed by Arctic foxes because it contains trimethylamine oxides, such as pollacks, gingiva, and shit. The amount should not be too large to exceed 40% of animal protein. When feeding a large amount of fox, add ferrous glucose to supplement the deficiency of iron. Otherwise it will cause anemia, the fox showed loss of appetite, indigestion, growth of young foxes stagnation, reduced male sexual desire or lack of sexual desire; female fox empty rate increased. In addition, certain marine fish such as capelin, sardines, sardines in the Far East, silver bream, barracuda, etc., as well as certain freshwater fish such as pupa, smelts, squid, red sea bream, squid and other thiamine containing enzymes, can destroy Vitamin B1. When used, the fish should be cooked and continued for a few minutes to inactivate the thiamine enzyme.
Explosion Proof Solvent Recovery Machine
We occupy a quality position of the Explosion-proof Solvent Recovery Machine in the market place, solvent recovery machine is the layout of the factory, The solvent recovery machine output of our factory is the largest; 
explosion-proof device for recovering solvent, solvent recovery apparatus and other products through the national explosion-proof inspection center Chinese verification, access to safe explosion-proof certification, so Calstar® brand can be assured.
Characteristics of explosion-proof solvent recovery machine
1, the two stage heating setting: according to the composition of the mixed solvent to recycling, the heater temperature for two set, so that different boiling point solvents in accordance with the order from low temperature and high temperature distillation in batches, the start time to avoid too high temperature, resulting in low boiling boiling over solid component and pipeline obstruction by;
2, fan running time setting: after the machine is shut down, the fan can continue to operate for a period of time, in order to improve the safety of operation;
3, the operation is simple: do not need someone to operate, staff only need to feed, turn on the power, clean up the residue can be, the whole process of automatic recycling automatic shutdown; save human resources
4, after the recovery of solvent quality as new: because the device uses the distillation separation principle, do not add any chemical composition
5, model a variety of: your company can choose according to the actual amount of waste of different models of models
6, the cooling way: the use of air-cooled cooling principle to improve the cooling effect, shorten the recovery time, more energy saving and environmental protection,
6, automatic shutdown system: can be controlled by time or temperature
7, recovery tank can be dumped, easy to remove residue
8, double circulation cooling, environmental protection without pollution,
9, fixed temperature shutdown: solvent recovery is completed, according to the steam temperature automatic shutdown;
10, time off: according to the time, double shutdown protection function;
11, ultra high temperature protection: when the machine exceeds the set temperature, automatic stop heating system;
12, temperature display no contact, no electric spark;
13, the temperature is accurate: the digital setting display temperature, the minimum value is 0.1
