It should be noted that it is above-mentioned during moon cake high-temperature baking, such as during maximum temperature, the manipulation row of control device 60 Blower 30 starts, and aspirates forced exhaust, favorably the micro metal ion gas of 10 vaporization at high temperature of apparatus for baking is discharged in time, with drop Metal catalytic hydroperoxidation reaction occurs for the grease in low moon cake, and oxidation reaction occurs for the grease reduced in moon cake, makes in moon cake The content of the rotten object of Oxidation of Fat and Oils harmful to health is less.

Compared with moon cake roasted in air environment, this equipment the oxidation that is oxidized of grease in roasted moon cake The content of rotten object is few, not as good as 10% in conventional roasted moon cake, so that the oxygen uptake ability of moon cake is greatly reduced, moon cake It is easier to save, the shelf-life of moon cake improves 0.5-1 times or even longer.

As second of embodiment of the application, a kind of intelligent baking method suitable for food is provided, for the ease of retouching It states, it next will be with nitrogen as being illustrated for protection gas, moon cake, as shown in figure 9, the baking method includes following step Suddenly.

Moon cake blank to be baked is got out, the gate 16 of manipulation apparatus for baking 10 is opened, by moon cake blank to be baked It is transferred in the roasted room of apparatus for baking 10, closes the gate 16 of apparatus for baking 10, the roasted room of apparatus for baking 10 and external air It is isolated.

Baking process is arranged in maneuver control device 60, and baking process includes and the protection gas parameter of time correlation connection and baking The setting value of temperature.The protection gas parameter includes 30 start and stop state of exhaust blower, oxygen content setting value, the opening and closing of the 1st solenoid valve 51 The setting value of state and aperture, 52 open and-shut mode of the 2nd solenoid valve and aperture.

Control device 60, which manipulates the movement of the 1st solenoid valve 51, to be made to be connected to the gas pipeline of 10 supplying nitrogen of apparatus for baking, to High pure nitrogen of the conveying as protection gas in the roasted room of apparatus for baking 10.

Control device 60 acquires the detection signal of lambda sensor 41, and judges that baking indoor air has based on the detection signal Nothing is fully drained.Detailed process includes the measured value for the oxygen content that lambda sensor 41 is fed back being obtained, when 41 institute of lambda sensor When the measured value of the oxygen content of feedback is lower than setting value, it is believed that the air in apparatus for baking 10 is all arranged by nitrogen protection gas Out, it closes symbol baking to require, control device 60 makes the judgement that the air in apparatus for baking 10 has all been discharged by protection gas, otherwise Continue to input nitrogen.It should be noted that in order to accelerate the discharge of the air in apparatus for baking 10, control device 60 can be manipulated Exhaust is reinforced in the starting of exhaust blower 30, is quickly discharged the air in apparatus for baking 10, reduces the time of air-discharging, improves and produces Energy.The nitrogen selects purity to reach analytically pure food-grade nitrogen, and purity can also be selected to reach 99% or more food Grade nitrogen, is understood to be above-mentioned high pure nitrogen.The nitrogen can also select argon gas to substitute.

When the air in apparatus for baking 10 is discharged entirely, control device 60 manipulates the starting heating of apparatus for baking 10, baking Food is toasted moon cake to be baked by preset baking temperature in the protection compression ring border that nitrogen is constituted.Specifically, control Device 60 processed obtains the baking temperature of the measured value of temperature measured by temperature sensor 42, measured value based on temperature and acquisition Setting value, manipulation apparatus for baking heating makes food to be baked in protection compression ring so that the measured value of temperature reaches setting value It is toasted in border by preset temperature.During baking, the valve opening that control device 60 manipulates the 1st solenoid valve 51 is turned down, The input quantity for reducing nitrogen keeps the nitrogen input of smaller flow, replacement part protection gas, nitrogen protection in the baking process The trace metal ion gas of 10 vaporization at high temperature of apparatus for baking can be discharged in time for the replacement of gas, and metal occurs for the advantageous grease that reduces Cui's oxidation；In addition, control device 60 manipulates the 2nd solenoid valve, extraction flow is adjusted, apparatus for baking 10 is made to bake indoor guarantor The pressure of shield gas is slightly larger than atmospheric pressure, and the advantageous leakage for reducing air reduces the generation of the rotten object of grease oxygen.It is baked Moon cake blank is immersed in the protection gas that high pure nitrogen is constituted, and moon cake blank is isolated with air, realizes moon cake blank and oxygen The isolation of gas toasts moon cake blank in nitrogen protection compression ring border, stops when completing until toasting, and the grease in moon cake is difficult Oxidation and metal catalytic hydroperoxidation reaction occurs, the content that the oil in moon cake refers to oxidation deterioration object, the oxygen uptake of moon cake are reduced Ability is greatly reduced.Here, above-mentioned baking process is identified as preceding baking, with subsequent possible roasting procedure phase region Point.

After the completion of baking, control device 60 manipulates apparatus for baking 10 and stops heating, in the protection compression ring border that nitrogen is constituted It is middle to cool down moon cake, it is cooled to technological temperature, such as room temperature.In cooling procedure, control device 60 can manipulate the 1st electromagnetism The movement of valve 51 tunes up valve opening, increases the flow of nitrogen, and moon cake is made to accelerate cooling, can also manipulate the movement of the 1st solenoid valve 51 Valve opening is turned down, the flow of nitrogen is reduced, makes moon cake Slow cooling.Moon cake is cooled to process warm in nitrogen protection compression ring border Degree, such as room temperature.The cooling technique is referred to as preceding cooling, mutually distinguishes with subsequent possible cooling technique.

Further, it needs to carry out coloring treatment to moon cake, makes moon cake golden yellow color, more attractive.In preceding cooling technique, When moon cake is cooled to technological temperature, after specified temperature, manipulation apparatus for baking opens gate 16, the 1st electricity of the manipulation of control device 60 The movement of magnet valve 51 increases the flow of nitrogen input.One layer of colorant is brushed on the surface of moon cake, keeps the thickness of coloring agent layer equal It is even consistent.The moisture evaporation in coloring agent layer for making moon cake surface in protection compression ring border, when the moisture of coloring agent layer is waved completely It is considered that coloring agent layer has been dried after hair, it is suitable for coloring baking.

The gate 16 for manipulating apparatus for baking 10 is closed, and control device 60 manipulates the movement of the 1st solenoid valve 51 and tunes up valve opening, Increase the gas transmission flow of nitrogen, is discharged so that apparatus for baking 10 is quickly baked indoor air, is fed back when based on lambda sensor 41 Measured value when judging that air is discharged entirely, control device 60 manipulates the movement of the 1st solenoid valve 51 and reduces nitrogen flow, and manipulates baking The starting heated baking of roasting device 10 carries out coloring baking to moon cake in nitrogen protection compression ring border.Coloring baking is referred to as After toast, with preceding baking phase region point.

After the completion of toasting afterwards, control device 60 manipulates apparatus for baking 10 and stops heating, by moon cake in nitrogen protection compression ring border It is cooled down.Here, the cooling is cooling after being referred to as.It is similar with preceding cooling, it can be by adjusting nitrogen flow, to change The cooling rate of moon cake.

When food is cooled to preset temperature, control device, which manipulates the 1st electromagnetism valve events, to be stopped conveying to apparatus for baking Protect gas.So far, the baking for completing food obtains edible food.

The toner selects yolk and honey is the mixed liquor that major ingredient is formulated, and wherein the volume accounting of honey is 18-29%, it is preferable that 21-24%, special 23%, the golden yellow color of moon cake and vivider is easily noticeable；The fragrance of moon cake It is denseer, easily cause the edible desire of people.

Further, in order to improve shelf-life of moon cake, a certain amount of coconut oil can also be added in above-mentioned toner, The volume accounting of coconut oil is 5-28%.When the volume accounting of coconut oil is 9%, it is also possible to 7-10%, the shelf-life mentions Ascending effect highly significant, under other same process conditions, the shelf-life of moon cake can improve 0.5-1 times again.

Alternatively, if the wetting that need to improve moon cake is softness, during above-mentioned preceding baking, in nitrogen protection gas Joined a certain proportion of water vapour, experiment shows that the volume ratio for accounting for protection gas when the water vapour being added is 5-18%, In, when the volume accounting of water vapour is 13%, the preceding obtained moon cake that toasts is softer palatable, and edible deutostoma is without very thirsty sense； In addition, soft mouthfeel has significant change to improve when the volume accounting of water vapour is 11-15%.During rear baking, A certain amount of water vapour is mixed into nitrogen protection gas, the volume accounting that experiment shows that be mixed into water vapour accounts for protective gas is 1-7% When, wherein when the volume accounting of water vapour is 2-4%, when special 3%, the cake skin of moon cake is softer palatable, and moon cake surface Coloring layer attachment it is stronger, be not easy to peel off；In addition, in the post-bake process mixed water vapour volume accounting it is excessive When, when such as larger than 25%, the shelf-life that will lead to moon cake is obviously shortened, and is easier to go mouldy.

It should be noted that if baking walnut cake, the stemness such as biscuit firmly crisp food when, do not need to protect in gas in nitrogen and be mixed into one The water vapour of ratio is conducive to shorten cooking time, improves production capacity.
