Abstract
The utility model discloses a nitrogen-filled vacuum packaging device capable of prolonging the shelf life of pleurotus eryngii. The nitrogen-filled vacuum packaging device comprises a feeding port and a discharging port, wherein the feeding port is connected with a chiller, the chiller is provided with a rapid cooling chamber, the downstream of the chiller is connected with a packaging machine, and the packaging machine is provided with a packaging film inlet, a sealing device, a nitrogen filling device and a vacuum pumping device and is connected with the discharging port. Metabolic activities of pleurotus eryngii substances can be reduced, external air can be isolated effectively, and the purpose of prolonging the shelf life of the pleurotus eryngii can be achieved. Moreover, the shelf life of the pleurotus eryngii can be prolonged, and the quality and flavor of the pleurotus eryngii are unchanged.
Description
Technical field
The utility model relate to a kind of prolong the pleurotus eryngii freshness date add the nitrogen vacuum packaging equipment.
Background technology
Pleurotus eryngii has another name called eryngo picks up the ears, and is to develop in recent years the rare edible mushroom new varieties edible, medicinal, dietotherapy that integrate of cultivating successfully.The mushroom body has happy almond flavor and such as the mouthfeel of abalone, thereby gains the name.Its meat is plump, and mouthfeel is fresh and tender, and taste delicate fragrance is nutritious, and the pleurotus eryngii bacterial context is plump, and quality is tender and crisp, and particularly stem dense structure, solid, milky white can all eat, be fit to stir-fry, burning, braised, stew, cook soup and hot pot material, also suitable western-style food; Even cook cold vegetable dish in sauce, mouthfeel is all very good, and mouthfeel is crisp, tough after the processing, is white to milk yellow, and outward appearance is good, can cook tens road delicious foods.And stem is called as " flat mushroom king ", " dried scallop mushroom " than the more crisp cunning of cap, tasty and refreshing, is fit to fresh-keeping, processing, and the equal edible of population is firmly got liking of people.
Pleurotus eryngii is nutritious, is rich in the mineral matters such as protein, carbohydrate, vitamin and calcium, magnesium, copper, zinc, can improve immune function of human body, and human body is had the effects such as anticancer, reducing blood lipid, ease constipation stomach and beauty treatment.Pleurotus eryngii also has reducing blood lipid, norcholesterol, promotion gastro-intestinal digestion, strengthens body immunity, strengthens body immunity, prevents the effects such as cardiovascular disease, and the utmost point is liked by people, and the market price is than 5 times of the high 3-of flat mushroom.
The difference of the flat mushroom of pleurotus eryngii and other general kinds, mushroom, coprinus comatus etc. is: the time that tissue tight, high resilience, harvesting are preserved afterwards, more general mushroom will grow.
The post-harvest fresh-keeping technology of pleurotus eryngii is that the pleurotus eryngii after adopting does not have through beating cold just direct packing, then play again cold preservation behind the warehouse-in, fresh food bacterium aqueous ingredients is high, organize tender, metabolic activity does not stop, so freshness date is not long, is generally 3-5 days, and fructification deliquescing, putrefactive phenomenon appear easily, affected quality and the economic benefit of fructification.
The utility model content
The utility model technical issues that need to address just are to overcome the defective of prior art, provide a kind of prolong the pleurotus eryngii freshness date add the nitrogen vacuum packaging equipment, it reduces the metabolic activity of pleurotus eryngii fructification, and effectively isolated outside air, reaches the purpose that prolongs the pleurotus eryngii freshness date.And not only having prolonged freshness date, quality and the local flavor of mushroom do not become.
For addressing the above problem, the utility model adopts following technical scheme:
The utility model provide a kind of prolong the pleurotus eryngii freshness date add the nitrogen vacuum packaging equipment, comprise inlet point and discharging opening, described inlet point is connected with fefrigerator, described fefrigerator is provided with snap-chill cabinet, described fefrigerator downstream connects wrapping machine, described wrapping machine is provided with packaging film import and closing device and is provided with and adds nitrogen device and vacuum extractor, and described wrapping machine connects discharging opening.
Working process of the present utility model is: the pleurotus eryngii after adopting is sent into first the fefrigerator refrigeration, fefrigerator is provided with snap-chill cabinet, the snap-chill cabinet temperature setting is set to-1 to 3 ℃, after pleurotus eryngii entity temperature was down to about 5 ℃, the vacuum of sending into baling line added nitrogen packed device, vacuumized and added nitrogen packed, it is fresh-keeping that pleurotus eryngii after the packing is sent into fresh-keeping warehouse again, preservation temperature-1 is to 3 ℃, and through the pleurotus eryngii fresh goods after this process packing, freshness date can extend to for 2 week.And not only having prolonged freshness date, quality and the local flavor of mushroom do not become.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1, the utility model provide a kind of prolong the pleurotus eryngii freshness date add the nitrogen vacuum packaging equipment, comprise inlet point 1 and discharging opening 2, described inlet point is connected connection with fefrigerator, described fefrigerator is provided with snap-chill cabinet 4, described fefrigerator downstream connects wrapping machine 5, and described wrapping machine is provided with packaging film import 6 and closing device 7 and is provided with and adds nitrogen device 8 and vacuum extractor 9, and described wrapping machine connects discharging opening.
Working process of the present utility model is: the pleurotus eryngii after adopting is sent into first the fefrigerator refrigeration, fefrigerator is provided with snap-chill cabinet, the snap-chill cabinet temperature setting is set to-1 to 3 ℃, after pleurotus eryngii entity temperature is down to about 5 ℃, the vacuum of sending into baling line adds nitrogen packed device, vacuumize and add nitrogen packed, it is fresh-keeping that pleurotus eryngii after the packing is sent into fresh-keeping warehouse again, preservation temperature-1 is to 3 ℃, through the pleurotus eryngii fresh goods after this process packing, freshness date can extend to for 2 week, and had not only prolonged freshness date, and quality and the local flavor of mushroom do not become.
It should be noted that at last: obviously, above-described embodiment only is for the utility model example clearly is described, and is not the restriction to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give all embodiments exhaustive.And the apparent variation of being amplified out thus or change still are among the protection domain of the present utility model.
