9, require the preparation method of described insect microwave drying technology according to right 6, it is characterized in that the use control method of microwave equipment.
Background technology:
The barley worm can be used for industries such as feed, food, health products, cosmetics through processing, for developing one of more resource insect.The protein content of barley worm is in first of all kinds of living animals, can be used as human wholefood, will become the third-largest insect industry behind silkworm, bee raising in China.Its larva is the succulence mollusk simultaneously, can be used as fresh and alive feed and is used to raise the higher special economic animals of value such as some ornamental fishes, bird, the frog, scorpion, snake, tortoise.The barley worm has become the protein feeds pillar of culturing animal for display and economic animal, makes mixed feed with barley worm substituted fish meal, and effect is very good.Its ight soil also can be used as good organic fertilizer, fish and livestock and poultry feed and uses.The barley worm can also be processed into that various nutrition height, mouthfeel are good through multiple modes such as baking, fryings, unique flavor, by high quality food that consumers in general liked.And in recent years, all there is the barley worm dry product outlet of some every year in China.
Handle the barley worm with microwave drying and have many outstanding advantages than conventional method: as shorten greatly process time, control easily, good product quality, color and luster and freshness can both keep, moisture and nutritional labeling loss are less, bacteria containing amount is low, treatment effeciency is high, cost is low, power consumption less, little, the working condition of floor space and environmental sanitation improve etc.Be applicable to the processing such as oven dry, powder process of various insects, barley worm.Flexible operation, temperature is even, puffed degree good, automation is high, control able to programme, runs without interruption in 24 hours.
Microwave processing is the emerging industry of China.For crudy and the industry modernization that improves the barley worm, be necessary already to use new science and technology, and advanced microwave technology has application promise in clinical practice in the oven dry of barley worm in barley worm preliminary working industry and deep processing.Microwave is meant the superelevation electromagnetic wave between radio and light wave at 3OMHz-300000MHz.At present, be applied in the centre wavelength 0.328m (frequency 915MHz) or the 0.1225m (frequency 2450MHz) of the microwave device in the food industry.
One, the application of barley worm microwave drying equipment in barley worm microwave drying
The processing of barley worm all needs to heat the albumen typing to be handled, with the activity of passive oxidation enzyme, and evaporation section moisture, volatilization polypide smell, softening tissue.Produce at present and go up mode of heating commonly used and carry out the albumen typing and handle, also can adopt steam albumen typing mode.
Result of the test shows that the barley worm quality of microwave mode processing is good, no significant difference, but the time of microwave albumen typing is short, can carry out continuously.And steam albumen typing is because steam water content height, and the raw material skin is subjected to temperatures involved, so the barley worm after the albumen typing almost do not have loss of weight, and part chlorophyll is damaged, and part runs off the contained nutriment of raw material with condensed water, and quality is not ideal.
Microwave mainly is the fuel factor of its generation in the application of barley worm microwave drying.When magnetron produces microwave, shine the barley worm to the influence that the polar molecule of barley worm inside is changed by microwave periodic, carry out cyclic activity with microwave.Because the frequency of microwave is very high, makes barley worm interior molecules high velocity impact and produced a large amount of frictional heat and improve material temperature rapidly, thereby reach the effect that is rapidly heated.
Two, the application of barley worm microwave drying equipment in barley worm drying
The material outside is heated in the general hot-air drying process, dry tack free, and heat inwardly transmits, and its direction is opposite with the direction that moisture diffusion is transmitted, and has influenced the outside evaporation of moisture.And microwave is inner heating, and the position that water content is high is heated up very fast.Therefore in microwave drying process, moisture is fast to outer field migration velocity by internal layer, and rate of drying is obviously faster than heated-air drying.The applied microwave drying has the following advantages in barley worm drying: (1) rate of drying is fast; (2) good product quality; Because barley worm surface temperature is not too high, the polypide appearance change is few, the green kingfisher of color and luster and anti-Tibetan, and fragrance loss is few, uniform drying; Simultaneously, form dry product easily because water evaporates speed is fast, dry product individual complete, color and luster is even.
Summary of the invention:
The processing of barley worm live body microwave drying
Embodiment:
At first carry out the quality place and see check, (individual strong active, individuality of insect and color no significant difference change with the raw material that conforms to quality requirements, size evenly), carry out albumen typing processing earlier by special process equipment, then according to the prescription requirement, primary raw materials and basic material are carried out composite, carry out quantitative package after being processed into insect feedstuff, finished process of producing product.
