How to choose electric frying furnace
Electric blast furnace can be divided into single cylinder electric blast furnace, double cylinder electric blast furnace, three cylinder electric blast furnace, multi-functional electric blast furnace. According to the actual need to fry the number of things to choose different functions of the electric blast furnace.
How to choose the right electric heat pipe for fryer
1, the consideration of power selection power calculation selection should consider the following three: 1, from the initial state, according to the specified time requirements to achieve the heating medium to the set temperature (operating temperature); (2) under operating conditions, the heat is enough to maintain the temperature of the medium; We should have a certain safety margin, generally 1.2. Obviously, the power selected from the larger, multiplied by the safety margin is the selected power. Calculation of required power for heating from the initial state (1) static fluid heating (2) flowing fluid heating (3) duct heater at atmospheric pressure air heating (P meter -- required power (KW); Q dispersion -- heat dissipated from the container at the set temperature (KW); Where: C1 is the specific heat of the heated medium. (Kcal/(kg·℃)C2 -- specific heat of the container. (Kcal/(kg·℃)M1 -- mass of medium heated. (Kg); M2 - container (system) mass (Kg); Δ T - set temperature and the initial temperature difference. (℃); T -- the time specified for heating the medium from the initial temperature to the set temperature. (h); F - heating medium flow rate, (generally take the maximum flow rate). (m /min); S - heat dissipation area. (m2); Q loss -- the amount of heat loss per unit area of the material at the set temperature. 3. In the calculation formula of the power required to maintain the medium temperature: p-dimension -- the power required by the electric heater to maintain the medium temperature. (KW) M1 increase -- increase in medium mass per hour.
