To determine the effects of vitamin C on the growth and pathology of diseased Nile tilapia, Egyptian fisheries researchers conducted experiments. The average weight of the test fish was 20 g, and the feeds supplemented with vitamins C0 mg/kg, 50 mg/kg, 150 mg/kg, 250 mg/kg, 500 mg/kg, and 1000 mg/kg were administered for 12 weeks. The growth of fish fed with no vitamin C feed was measured. The addition of vitamin C 50 mg/kg prevented the lack of symptoms of the fish. The addition of 150 mg/kg increased the weight gain, feed conversion rate, specific growth rate and protein efficiency of tilapia. The protein content of the fish body increases with the addition of vitamin C in the feed, and the fat content decreases. The content of vitamin C in fish tissue is spleen, liver, muscle and kidney. Feeding tilapia with bacteria to different levels of vitamin C feed, the mortality rate of diseased fish without feeding vitamin C feed is more than 90%, and the survival rate of sick fish fed with vitamin C 1000mg/kg feed is over 90%. The symptoms of pathological infection gradually disappeared. Ice Maker

Ice maker is a refrigerating mechanical device that generates ice by cooling water by an evaporator through a refrigerant in a refrigeration system. A refrigeration system is used to manufacture ice by using a water carrier and passing a certain device under a power-on state. According to the principle of the evaporator and the production method, the shape of the generated ice cubes is also different; people generally use an ice shape to divide the ice maker into a granular ice maker and a flake ice maker.
We have three series of ice maker: Snowflake, Block, Flake.
Snowflake: IMS series automatic flake ice makers are the entire computer-controlled high-tech products. There are 9 specifications 17 types of flake ice makers such as IMS-25.IMS-40.IMS-50.IMS-70.IMS-85.IMS-100.IMS-120.IMS-150.IMS-200,etc. This series of products have entered the rank of the leading domestic level. In structure, stainless steel is adopted as enclosures, boasting elegant appearance. They have characteristics of continuous ice-making, fast ice-making speed and large ice-making capacity etc. They are widely used in hospitals, schools, laboratories, research institutes, food preservation in supermarkets, fishing refrigeration, medical applications, chemical and food processing industries, etc. This series automatic flake ice makers have adopted Italian Oute Shi Haitec two-stage reducer and Korean GGM motor, featuring low noise, stable and reliable operation. They have adopted the ice-making and ice-breaking structure with the line of chip ice-making chamber separated from the evaporator, resulting in high ice-making efficiency and large ice-making capacity. They are fully computer controlled with functions of shutdown protection in case of full of ice and water deficiency, etc.
3)Side air inlet and side air outlet; mixing type ice making; highly transparent ice.
4)Detection and protection in case of overload, water shortage and full ice level.
5)Highly efficient freon-free compressor, economical and energy-saving.
6) Widely applied to pubs, ice bars, hamburger shops, cold drinks shops, fast food restaurants, bake-ries and cafes.
Flake: Material: Inner and outer cylinders are made of alloy steel. Cast aluminum is available for top/bottom closures of 12T and below, alloy steel is available for top/bottom closures of 15T and above. The rotor is made of alloy steel and the ice removal blade is made of spiral stainless steel. Stainless steel also could be adopted for top/bottom closures and rotor as requested by customers. The bearing is famous global brand.
Configuration: Rotor, ice removal blade, water receiving pan, water circulation are standard components. Speed reducer, metering pump, electric controlling system are optional components.
Specifications: 0.5T~60T.
