Nitrogen ice cream is made using liquid nitrogen, we all know that the temperature of liquid nitrogen itself is very low, so it will be very good to form a cooling effect. Liquid nitrogen. It is inert, colorless, odorless, non-corrosive, non-flammable, and has an extremely low temperature. Nitrogen makes up the majority of the atmosphere (78.03% by volume and 75.5% by weight). Nitrogen is inactive and does not support combustion. Vaporization causes frostbite from large amounts of heat absorbing contact. At atmospheric pressure, the temperature of liquid nitrogen is -196°C; 1 cubic meter of liquid nitrogen can be expanded to 696 cubic meters of 21°C pure gaseous nitrogen. Liquid nitrogen is colorless, odorless, low temperature liquid and gas under high pressure. Smoking ice cream production is to use the simple principle that liquid nitrogen absorbs a lot of heat when it vaporizes. The main ingredients of ice cream are water, cream, jam and other auxiliary ingredients. To make smoky ice cream, the first thing we need to do is to mix the ingredients into a thick semi-solid state, and then put this into an appliance containing liquid nitrogen, we will find that the cream and other ingredients will instantly turn into solid ice cream. Simply put, when the cream and other ingredients come into contact with the liquid nitrogen, the -196 degree Celsius liquid nitrogen vaporizes and absorbs the heat from the cream and instantly solidifies.

How much does nitrogen ice cream cost

A liter of liquid nitrogen sells for about 7 yuan, a liter of liquid nitrogen can do about 10 copies of ice cream, if you add the production of ice cream, raw materials, equipment costs, etc., an ice cream of the integrated cost of not more than 3 yuan, the general price of sales of a copy of ice cream for 8 yuan, the gross profit of about 5 yuan / copy. This * average sale of six hundred copies, there are three thousand dollars of gross profit, a month down to 90,000 yuan of gross profit, after deducting the store rent, employee wages, utilities and other miscellaneous expenses, a month of net profit of at least 50,000 yuan
