Description
Technical Field
The application relates to a grain and oil seed frying machine, in particular to a roller seed frying machine with double-exhaust-channel.
Background
The grain and oil seed frying machine is mainly applied to an oil preparation process or a food processing process, for example, the grain and oil are baked, and is particularly applied to baking and seed frying of special oil materials such as sesame, peanut, camellia seed, walnut kernel, linseed and the like, and the prepared grease or processed food has special fragrance after baking. The grain and oil seed frying equipment utilizes hot air or flame generated by burning fuel to continuously heat a frying pan or a roller for baking materials, simultaneously continuously turns the materials, and fries cooked oil seeds through control of a certain time and temperature, so that the oil produces unique good flavor.
Currently, the equipment for stir-frying grains and oil is divided into two types: one type is a small-scale or workshop type soil kitchen frying pan, namely a pot is placed on a kitchen heated by direct fire, oil seeds are baked and fried in the pot, and the materials are continuously turned over by manpower, so that the frying pan is applied to the traditional workshop production of preparing ground sesame oil by sesame, the old-fashioned production of which inherits for hundreds of years is eliminated, and the defect is obvious: low heat utilization rate, high labor intensity and serious environmental pollution. The other type is drum-type seed frying equipment, wherein hot air generated by burning fuel in a hot air furnace is introduced from the side of a seed frying machine by using a draught fan, is discharged from the top of the seed frying machine, indirectly heats oil or grain in a rotating drum, continuously turns over and continuously fry the oil or grain in the seed frying drum for drying, and ensures that the oil is fried to generate good flavor and taste or moisture of the grain is dried by heating.
However, the common roller seed frying machine mainly comprises a frame, a seed frying roller, a material inlet (outlet) device, a hot air inlet (outlet) and a driving device. In actual operation, the temperature of the stir-fried oil reaches more than 250 ℃, hot air or smoke after the stir-frying is directly discharged from a smoke outlet at the top of the seed frying machine, the rest temperature is about 200 ℃, the direct discharge at the temperature causes considerable heat energy loss, and meanwhile, the material to be stir-fried is heated from normal temperature to the stir-frying temperature, and a large amount of heat energy is consumed. When the normal temperature material enters the seed frying equipment, the material needs to be fried rapidly by strong fire, but the temperature of the oil is low at the moment, and the material is easy to be burnt by high-temperature frying, so that the color of the prepared oil is deepened.
In order to utilize the heat energy of the flue gas at the discharge port, a heating sleeve is added on the screw conveyor before the seed frying machine, and the flue gas waste heat is utilized for heating, so that although a part of heat energy can be utilized, the heating effect is limited due to the short residence time of the conveyor, the flue gas waste heat cannot be effectively utilized, moreover, the screw conveyor is not necessarily applied to the grain and oil frying process, and equipment and power consumption must be increased to realize the utilization of the waste heat, so that the screw conveyor is not necessarily feasible in practical application.
In summary, the above grain and oil seed frying device has the following disadvantages:
(1) The unit heat energy consumption is large, the materials are required to be heated from normal temperature to seed frying temperature, then seeds are continuously fried, the heat loss is large, and the temperature of directly discharged smoke is about 200 ℃.

An inner cylinder is arranged in the heating roller, hot air is introduced into the inner cylinder, and a material channel is arranged between the heating roller and the inner cylinder. Therefore, in the heating section, the materials in the heating roller are heated by the smoke of the inner and outer hot air smoke channels, so that the materials are effectively heated and heated, and enter the seed frying roller when the temperature is close to the seed frying temperature.

(4) On the basis of the original seed frying function, the machine has the function of utilizing the residual heat energy of hot air after frying the materials, has compact structure, and does not need to additionally increase equipment and power for customers.
However, the seed frying machine also finds some problems in the actual use process, the smoke flow path is complex, the flow resistance is high, meanwhile, smoke dust is easily accumulated in the smoke channel and is not easy to clean, in addition, the structure of the equipment is complex, the manufacturing difficulty is high, and the like, so that the operation and maintenance cost of the equipment is obviously increased, that is, the energy saving benefit of the equipment is reduced.
