The invention provides an efficient and energy-saving roasting pan. A main body comprises a large body, an upper cover, heaters, a pan body, a food rolling-over device, an air inlet hole and a cooling fan, wherein the heaters comprise an upper heater and a lower heater; the efficient and energy-saving roasting pan is characterized in that the large body is used for containing the pan body (3), the food rolling-over device (11) and the lower heater (44); the large body (1) provides a heat source for providing conductive heating to bottoms of foods; the upper cover (2) provides a heat source for providing heat radiation or light illumination heating to upper surfaces of the foods; the upper cover (2) covers the large body (1) to form a three-dimensional heating cavity (55) with the upper part for carrying out heat radiation or light illumination heating and the bottom for providing conductive heating; the cooling fan is used for providing a constant temperature into the three-dimensional heating cavity (55) or relatively cooling and heating the inner part of the three-dimensional heating cavity (55); the cooling fan is arranged at the outer part of the three-dimensional heating cavity (55); and one food rolling-over device (11) is used for rolling over the foods to carry out uniform heating and three-dimensional heating on the foods. The efficient and energy-saving roasting pan has the characteristics of good cooking effect, easiness of dismounting and mounting, easiness of cleaning and wide applicable range.

The invention discloses a high-efficiency and energy-saving baking pan and its heating, cooling, and exhaust methods. A temperature control probe, the heater includes an upper heater and a lower heater, the cooling fan is arranged outside the three-dimensional heating chamber, one end is connected to the outside air, and the other end is connected to the inside of the three-dimensional heating chamber, Mix the external low-temperature air with the high temperature inside the three-dimensional heating chamber by blowing air, keep the temperature inside the three-dimensional heating chamber constant or relatively cool down the inside of the three-dimensional heating chamber, and heat the water vapor in the three-dimensional heating chamber along the air outlet or the The gap on the main body is exhausted. The invention has the characteristics of good cooking effect, easy assembly and disassembly, easy cleaning and wide application range.

The invention discloses a cylinder head and a gas engine, which are applied to a gas engine modified on the basis of a diesel engine. The throat is provided with a first intake valve seat, and the second intake throat is provided with a second intake valve seat, and the height H of the first intake valve seat from the bottom surface of the cylinder head is 1 Greater than the height H of the second intake valve seat from the bottom surface of the cylinder head 2 . Compared with the traditional symmetrical arrangement of two intake valve seat rings, this cylinder head can effectively reduce the airflow hedging interference in the direction of the center line of the two intake valves, thereby reducing the loss of airflow kinetic energy, which is more conducive to Improves the tumble effect in the combustion chamber.

The invention discloses a production process of heat-resistant iron oxide black, which belongs to the field of chemical pigments. It is a production process of heat-resistant iron oxide black. The invention can realize dehydration and drying after the iron oxide black filter cake is obtained by adopting the sodium hydroxide oxidation method dry, and preliminarily powdered and mixed with white carbon black and powdered refractory materials, and then after high-speed uniform dispersion, innovatively introduce an entrainment device, using anhydrous ethanol vapor to entrain surfactants and coupling agents , based on the fluidity and contact properties of the gas, the powdery refractory material is uniformly and comprehensively covered on the surface of the iron oxide black, and the coating dead angle is not easy to appear, forming a dense high temperature resistant film, which significantly improves the resistance of the iron oxide black High temperature performance, acid resistance, alkali resistance, light absorption, tinting strength, compatibility and dispersibility have all been greatly improved.
