Solar constant temperature barbecuing device

Abstract

The invention provides a solar constant temperature barbecuing device. The solar constant temperature barbecuing device comprises a solar heat collection tube, a light condenser plate and a support; the light condenser plate is arranged on the support; the solar heat collection tube is connected with the support and arranged on the inner side of the light condenser plate; the solar constant temperature barbecuing device also comprises a heat accumulation tube which is arranged on the inner side of the solar heat collection tube and filled with heat accumulation materials; the cross section of the light condenser plate is in a U shape; the solar heat collection tube is arranged in a U-shape opening of the light condenser plate; the heat accumulation materials are inorganic salt composite phase change heat accumulation materials or expanded graphite composite phase change heat accumulation materials. According to the solar constant temperature barbecuing device, the energy regulation and the temperature control are performed on the solar barbecuing process through the phase change heat accumulation materials and accordingly the defect of the nonuniform heat of the solar energy is overcome and harmful materials such as heterocyclic amines which are harmful to the health of human bodies can be effectively reduced.

Description

technical field [0001] The invention relates to a heater, in particular to a solar constant temperature barbecue device. Background technique [0002] In recent years, with the increasing prosperity of the catering industry, barbecue has spread all over the city's business districts and is popular all over the country. However, barbecue also brings environmental pollution problems at the same time. The barbecue mainly uses coke and charcoal as fuel, and a large amount of dusty oily smoke is generated during the combustion process, which seriously affects the urban environment. In addition, barbecue itself also has certain health problems. The threat to health of barbecue mainly comes from two types of dangerous chemical reactions in the process of barbecue: the smoke generated by the dripping fat when it meets charcoal is full of carcinogenic polycyclic aromatic hydrocarbons, When the smoke surrounds the food, these polycyclic aromatic hydrocarbons will also adhere to the s...

AI Technical Summary

Problems solved by technology

However, solar energy itself also has the defect of volatility, and solar radiation will vary greatly during the day

Therefore, the use of solar energy for barbecue must have problems of uneven heat and temperature fluctuations, which requires certain technical means to stabilize the heating temperature of solar energy
