Cas number 7681-82-5 Frozen Meat Breaker And Grinder
Frozen meat breaker/frozen meat breaker/meat grinder/meat mincer is the first step of high quality products production. They are used for pre-breaking frozen meat blocks stacked on pallets. It includes bone saw series, frozen meat cutting machine, frozen meat flaker,grinder series, etc. Customers will use different machines depending on the processing needs and to form an automatic production line. No need of defrosting of the meat, Helper`s breaker series has been designed to cut off a whole block of meat in meat pieces with a blades system, avoiding second time pollution and keeping meat texture.
Large frozen meat breaker series: Bone saw, Frozen meat cutting machine, frozen meat flaker.
Frozen meat grinder series: JR-120, JR-140, JR-300, chopping and grinding combination system.

Molecular formula NaI
Molecular weight 149.89
Sodium iodide
White cubic crystal or powder. Odorless, bitter and bitter. It is easily soluble in water, ethanol, acetone, glycerin, liquid ammonia, liquid sulfur dioxide, and the aqueous solution is slightly alkaline. Deliquescent, absorbing water in the moist air and clotting. It gradually decomposes on contact with air to precipitate iodine, which gradually becomes brown.

Product use The chemical industry is used as an important raw material for the preparation of inorganic and organic iodides. It is also used as a co-solvent for iodine and for the preparation of iodine emulsions. The pharmaceutical industry is used to produce expectorants and diuretics. The photosensitive industry is used as a sensitizer for film, and it is used as spot analysis and other analytical reagents in analytical chemistry. Used as an oxidant in chemical reactions.
When the temperature is lower than 65.6 ℃, sodium iodide forms various hydrates with uncertain water content in the aqueous solution. The dihydrate is precipitated from the solution at room temperature as colorless prismatic crystals, and the pentahydrate can be precipitated within 13.5 ～ 31.5 ℃. It reacts with sulfur dioxide to form corresponding stable compounds. It has reducibility and can be oxidized by oxidizing to free iodine.
