Description
Technical field
The utility model relates to a kind of controlled atmosphere fresh-keeping packing equipment with the vacuum pre-cooling function, belongs to far products and food refrigerated and controlled atmosphere fresh-keeping packing machine tool field.
Background technology
Fresh fruit, particularly berries strawberry, red bayberry etc., it is because of no shell pericarp, and season, joint was short, preserved and generally was no more than two time-of-weeks, and its storage fresh-keeping is very difficult.At present, the berry fruits of similar red bayberry, one of actv. preservation method are the back precoolings rapidly of gathering; Make the fruit temperature reduce to 0-2 ℃ rapidly from external high temperature; Then, realize guaranteeing the quality, protecting look, conformal, guarantor's flavor, prolong its storing and shelf life to carry out controlled atmospheric packing; Simultaneously also can slow down the fall off rate of its soluble solid content and titratable acid content, and can slow down going mouldy of fruit greatly.Yet the berry of similar red bayberry class is not owing to have shell or pericarp, and mechanical damage such as be squeezed when gathering, transporting and storing easily.At present, the pretreatment process of employing as: cleaning, vacuum pre-cooling, controlled atmospheric packing equal segments are carried out, and through just coming into the market after this several roads program, arrive in customer's hand.This treating process; Not only can produce the artificial mechanism damage, and be prone to cause its nutrition leak, the shelf life poor effect that can prolong far products; Particularly behind vacuum pre-cooling owing to need capsule part packing again; More be easy to generate various damages this moment, therefore how optimize its fresh-keeping and storing technology, being still needs to make great efforts improved problem.
About the process of Waxberry preservation, mainly be to adopt to add antistaling agent or adopt bubble chamber method on the rocks at present, these methods are to a certain degree playing the Waxberry preservation effect, but also do not solve the fresh-keeping problem of red bayberry from output to consumption fully.
For red bayberry, because of its collecting period on the occasion of summer high temperature, have field heat and self respiration heat after the harvesting, the back precooling of therefore gathering is more early fast more, its loss of nutritive components can be lacked more, freshness date is long more.The utility model combines the vacuum fast precooling with the low temperature controlled atmospheric packing; Gather in the scene of being applicable to, the scene is precooling and packing directly, when carrying out controlled atmospheric packing, removes the field heat of product; Make the product temperature after the packing drop to predetermined value (like 0-20C) rapidly; For example work as red bayberry and be reduced to about zero degree from the summer temp 30-350C that plucks, respiratory intensity can reduce 80%-90%, can suppress its respiration timely and effectively.Precooling and one step of controlled atmospheric packing are accomplished, reduced the pilot process of precooling and controlled atmospheric packing, can reduce damage effectively, keep nutritional labeling, it is rotten to delay its aging.
The utility model content
For addressing the above problem; The purpose of the utility model is: a kind of refrigeration controlled atmosphere fresh-keeping packing machine that in controlled atmospheric packing, carries out vacuum pre-cooling is provided; The fresh-keeping packaging device that has particularly combined the function of vacuum pre-cooling machine and gas-control packing device can reduce the mechanical damage of cost and pilot process effectively, shortens product and comes into the market processing time in early stage; Look, conformal, guarantor's flavor are guaranteed the quality, are protected in realization, prolong the storage shelf life of fresh fruit of vegetables.
For reaching above-mentioned utility model purpose; The technical scheme of the utility model is following: a kind of controlled atmosphere fresh-keeping packing machine with the vacuum pre-cooling function; Comprise the full-replacement type wrapping machine; Said full-replacement type wrapping machine comprises vacuum chamber, is provided with water vessel behind the said vacuum chamber, and said water vessel connects vacuum pump and refrigerating unit through vacuum-pumping pipeline, muffler, feed tube.
According to the controlled atmosphere fresh-keeping packing machine of the band vacuum pre-cooling function of an embodiment of the utility model, said vacuum chamber top is provided with heat sealing film, mold and vacuum (-tight) housing, and said heat sealing film below is provided with bed die.
According to the controlled atmosphere fresh-keeping packing machine of the band vacuum pre-cooling function of an embodiment of the utility model, said vacuum (-tight) housing is provided with takes out inflation inlet, and said bed die is provided with down takes out inflation inlet.
Controlled atmosphere fresh-keeping packing machine according to the band vacuum pre-cooling function of an embodiment of the utility model also is provided with pressure transformer and cylinder on the said vacuum (-tight) housing.
The utility model is the process equipment that adopts vacuum pre-cooling and controlled atmosphere to process at one time to the fresh fruit of vegetables of gathering.The utility model can be according to conditions such as the precooling requirement of the refrigeration of variety classes fruits and vegetables and controlled atmosphere fresh-keeping packing, packing of product amount, initial temperatures; And the temperature that reaches of fresh-keeping requirement etc. is regulated; In the controlled atmospheric packing operation; Product is cooled to required preservation temperature, thereby can keeps the fresh of fruits and vegetables better.
Maximum precooling amount influence factor mainly comprises the temperature of product after the preceding humiture of packaging product kind, packing box size, Packing Unit, the packing of product, the packing of product and the time of continuous controlled atmospheric packing.
With the controlled atmospheric packing red bayberry is example, calculates required maximum precooling amount, the vacuum precooling device part that designs and mate the utility model according to maximum precooling amount according to the above-mentioned factor that relates to cold.
Vacuum chamber internal volume 0.006m3 adopts 380V.The pre-cooler installed power: (estimate refrigerating capacity q0=Cp*m* (tx-tz), the temperature of red bayberry is made as 300K (270C) before tx-packing to choose condensation unit 4HP; Tz-the temperature of red bayberry after packing is made as 273K (00C), and Packing Unit m gets 500g and calculates; The Cp of red bayberry is less than the Cp value of water; The Cp value 4.2KJ/ (Kg.k) of estimation water intaking calculates, and calculates with the double packing, and the total replacement controlled atmospheric packing is per hour packed 400 boxes and calculated.Gained is the KJ=10206KJ of refrigerating capacity Q0=(4.2*0.5*27*300) per hour, promptly on 4HP), vacuum pump exhaust capacity and evaporator are caught outlet capacity need mate unanimity, and evaporating temperature is-5 ℃, and final vacuum can reach 100Pa, adopts the R134a refrigerant.Water vessel places the vacuum chamber side or behind, water vessel inside adds plate baffle for light pipe, the catching outlet capacity and should confirm of water vessel according to the exhaust capacity of vacuum pump, but receive the influence of its evaporating temperature simultaneously.
