Description
Technical field
The invention belongs to fruit jelly technical field of drying, be specifically related to a kind of bergamot fruit series of products full-automatic energy-saving dry technology.
Background technology
Bergamot fruit has another name called Fructus Citri Sarcodactylis, for the evergreen dungarunga of Rutaceae.Save in Guangdong, Fujian, river and Jiangsu and Zhejiang Provinces etc. at China's main product.Fructus Citri Sarcodactylis nature and flavor are pungent, bitter, sour, warm, containing plurality of Chinese compositions such as citropten., diosmin, Hesperidin, flavonoid glycoside and active polysaccharides, have the effects such as invigorating the spleen and regulating the stomach, relaxing muscles and tendons to promote blood circulation, activating QI to eliminate phlegm；Bergamot fruit is nutritious, and bergamot fruit is nutritious, and protein (1.2%) and vitamin C (9.45mg/100g) content are high, has sodium low in calories, low and the advantage of high potassium, distinctive Fructus Citri Sarcodactylis Oleum sesami, especially a kind of rare spice.
Start from the Guangdong-style preserved fruits industry of Tang and Song Dynasty, exceeded thousand loads, be China's traditional food with local characteristic.Since the Ming Dynasty, Chaozhou-Shantou region villager just understands to add bergamot fruit and joins several kinds of Chinese medicinal materials, is processed into medicated diet homology fruit jelly goods, its color is glossy pitch-dark, state is continuous such as cream, have long-pending dispel the wind, effect such as regulate the flow of vital energy, act as expectorant of whetting the appetite, can treat for stomachache, abdominal distention, the disease such as vomiting and abundant expectoration cough with asthma；Additionally by fresh bergamot fruit chip drying, can use as excellent medical material.
During fruit jelly produces, being dried is one important operation, its objective is to remove the moisture pickled in rear semi-finished product, in order to further deep processing, transports, store and uses.At present, manufacturer still uses traditional outdoor natural suning method when Fructus Citri Sarcodactylis fruit jelly is dried mostly, although using the method more convenient, energy free consumption, but this method is without facilities such as protection against rodents, flyproof worm, anti-foreign bodies, easily cause product contaminated, also there are the drawbacks such as occupation of land is many, and labor strength is big, simultaneously, this method is affected greatly by weather, cannot be carried out producing completely at rainy weather.It addition, the general scale of out-of-door drying method is smaller, efficiency also ratio is relatively low, it is difficult to industry is run business big and strong.Part producer is had to use oven drying method that the agricultural byproducts such as fruit jelly are dried at present, wherein using more is to be dried in sealing space using steam or electric energy as thermal source, but this method consumes mass energy, operating cost is higher, it is also possible to produce a large amount of fire emission simultaneously, does not meets the theory that Modern Green produces.Ye You producer uses the Green production method that solar energy is dried as thermal source, also there is the Green production method using solar energy drying room to be dried, it is high that solar energy air heat collector adds hot-air efficiency, but have that capacity is little, heat-insulating property is bad, the overcast and rainy and shortcoming that cannot produce night, the labor intensity of workman is big simultaneously；Using water tank to carry out complementary heating at night in solar energy storage mode, but thermal conversion efficiency is low, hot air drying temperature is undesirable.
Solar energy is utilized to produce in the mode of hot blast, air collector is high because of the thermal efficiency, firing rate is fast thus be widely used, but solar energy irradiates and there is intermittence, even if on sunny daytime, the irradiation of the sun also can change, and the most even cloud hides and also there will be the situation that hot blast temperature reduces day, and which is applicable to be dried baking temperature, drying time without the common fruit jelly being strict with.Liquid for heat collection device, generally uses water for adding thermal medium, and hot blast temperature is the most stable, but thermal conversion efficiency is relatively low, and hot air drying temperature is undesirable.Thermal conductance oil homogeneous heating, homoiothermic temperature control is accurate, can the most quickly produce high temperature, and heat-transfer effect is good, can be as good energy storage and heat eliminating medium.
Bergamot fruit is because of its Chinese medicine ingredients and abundant nutrition material, and to hot hypersensitivity, industrialization produces continuously and also has higher requirements hot blast temperature stability, the aromatic odor that bergamot fruit is special simultaneously, should give as far as possible and retain in hot-air drying process.Fructus Citri Sarcodactylis is dried specification and pickles whole fruit, strip, bulk and lamellar four kinds, bergamot fruit type, size, heating surface area, final moisture content are different, useful load, temperature, humidity, wind speed, conveyer belt speed are also differed by the condition being dried, the whole fruit processed such as pin hole, need to slowly be dried at the hot blast that temperature is slightly lower, and block need can rapid draing at relatively high temperatures；Lamellar bergamot fruit needs to be dried to relatively low water content and to product surface outward appearance without being strict with, whole fruit product then overall water content is higher, therefore nebulizer can be closed in dry run, but strip and block then need to make finished product keep suitable moisture and require product surface not occur shrinkage affects product appearance, moisturizing need to be atomized with glycerol；Additionally sealing posterior segment, tunnel to be dried, hot blast humidity should not be the most dry, in order to avoid destroying Fructus Citri Sarcodactylis product quality.
In order to solve the technical problem that above-mentioned bergamot fruit dry run exists, it is necessary prior art is improved with equipment, probe into a kind of PLC full-automatic control system, the hot blast of temperature stabilization is provided, meet equipment and method that many specifications bergamot fruit high-quality is dried, both efficient energy-saving, realizes again health, safety and automated production.
