Technical Field

The invention relates to a baking device, in particular to an infrared oat baking enzyme-inactivating processing device.

Background

Oat belongs to cereal crops which are one of eight grain crops, integrates nutrition and health care functions, has multiple physiological functions of reducing blood cholesterol content, delaying postprandial blood sugar rise, reducing risks of cardiovascular and cerebrovascular diseases and the like, and is an important healthy food resource, oat grains contain higher nutrients such as protein, fat, beta-glucan, mineral substances, phenolic acids and the like, but compared with other grains, the fat content of oat is quite high, the fat content of naked oat varieties in China is mostly 7% ~%, unsaturated fatty acids account for more than 80% of total fatty acids in oat oil, wherein linoleic acid accounts for 38% ~% of the unsaturated fatty acid content, oleic acid accounts for 30% ~% of the unsaturated fatty acid content, the oat oil not only contains higher oil content, but also has high lipase activity, the characteristic makes oat processed products need to be subjected to enzyme deactivation treatment firstly, otherwise, the lipase catalyzes and hydrolyzes triglyceride to generate free fatty acids, the free fatty acids are further oxidized by lipoxidase and peroxidase, so that rancidity of the products is seriously influenced, the oat metamorphic enzyme deactivation is realized by a novel conventional technology for deactivating the conventional lipase and baking the lipase for deactivating the normal-temperature lipase.

For example, the traditional stir-frying enzyme deactivation has the disadvantages of high labor intensity, incapability of continuous production, uneven temperature, difficult quality control, easy scorching and large quality difference between one pot and another pot; the enzymes are deactivated by normal pressure steam, the steam is introduced, the steaming is carried out for a plurality of hours, the energy consumption is large, special equipment of a high-pressure boiler is needed, and in addition, the oats after the enzymes are deactivated by the normal pressure steam are lack of the unique aroma taste of the oats. The microwave enzyme deactivation requires expensive equipment and has higher cost.

The current situation of belt baking equipment, major structure are all including relative confined casing, are located inside conveyer belt, and heating device is on the conveyer belt of placing the material, through heating device, directly or indirectly heats the material to the material that the stoving is heated is often used for the food processing field. For example: application No. 201610471161.8 crawler-type cardboard dryer, application No.: 201610753283.6 Belt microwave dryer, application number: 201711426314.8 combination of mesh belt type dryer, application number: 201010299908.9, belt food dryer, application No.: 201220737849.3 and 201620907176.X, 201610735002.4, a conveyor-type drying apparatus; 201610403819.1, the full automatic belt dryer. A conveyor type dryer using an electric direct heating system as described in application No. 201610735002.4. The heat source of the above patent adopts electrical heating to convert into heat energy, but the drawback is that the electricity consumption cost is high, because behind the electrical heating air, a large amount of hot air dwell time in the heating cavity is too short, then just is taken away by the air exhauster, and energy conversion efficiency is low, the heat energy loss of more than 65%. There is also a type of drying apparatus using natural gas, coal gas, etc. as a heating source, for example, application No.: 201210277847.5, application No.: 201220043607.4, application No.: 201720670868.1, the food can be baked by generating hot air by gas heating. Also by heating the air, the air medium will consume some heat energy, while the main component of natural gas is alkanes, of which methane is the majority, and small amounts of ethane, propane and butane, in addition to hydrogen sulfide, carbon dioxide, nitrogen and moisture, and small amounts of carbon monoxide and trace amounts of rare gases such as helium and argon. To aid in leak detection, mercaptans, tetrahydrothiophenes, and the like are also used to odorize the natural gas before it is sent to the end user. Natural gas has a high calorific value and is free from any problem when used as a fuel, but when used directly for baking foods, substances such as hydrogen sulfide and mercaptan contained in the natural gas generate bad flavor substances in the combustion process, so that the flavor of the products is deteriorated, and the taste and the flavor are influenced.
