Description
Technical field
The present invention relates to food preservative technology field, be specifically related to a kind of food fresh keeping vacuum precooling machine.
Background technology
An important indicator of food is exactly freshness, and consumer is also more and more higher for the requirement of its freshness.Normal temperature is preserved can not meet the requirement of people to its freshness.Reducing temperature is a kind of effective ways generally adopted, and now just needs to use vacuum precooling machine.
Vacuum precooling machine (English name: vacuum cooler or vacuum cooling machine) uses vacuum pre-cooling technology, to utilize in vavuum pump extracting vacuum groove air and steam to reduce the cooling process equipment of vacuum chamber internal gas pressure.At low pressure, the boiling point of water reduces, and evaporation latent heat increases, cooled object surface Free water generating gasification phenomenon, takes away self and bad border heat, reaches the effect that cools.
The operation principle of vacuum precooling machine is that the boiling point of water is 100 DEG C, and heat of evaporation is 2256KJ/kg a normal atmosphere pressure; When pressure drop is to 610 handkerchief, the boiling point of water is 0 DEG C, and heat of evaporation is 2500KJ/kg.Along with the reduction of air pressure, the boiling point of water reduces, and the heat that the water of evaporation unit quality consumes increases.Vacuum pre-cooling is exactly under vacuum, makes water indoor with the evaporation of lower temperature in application of vacuum rapidly, in the process, consuming more heat transfer, when not having external heat source, in vacuum chamber, creating refrigeration.Vacuum pre-cooling technology principle is simple, and cooling rate is high, is widely used in agricultural products fresh-keeping, transport and stores.
Vacuum pre-cooling is broadly divided into three phases: vacuumizing phase, cooling stage and press the stage again, in decompression process, i.e. vacuumizing phase, the fruits and vegetables that moisture more easily gasifies, cooling effect is better, because external surface area and the ratio of its volume of fruits and vegetables, the number that is slightly close, free water content of the histological structure of fruits and vegetables own determine its vacuum cooled effect.That is, external surface area is larger with the ratio of volume, and histological structure is more coarse, and free water content is higher, and cooling effect is better, and external surface area is less with the ratio of volume, and its cooling effect is poorer.
During vacuum pre-cooling, the moisture loss of General Requirements fruits and vegetables is no more than 3%, otherwise will cause fresh-keeping product atrophy, in order to make vacuum pre-cooling faster, better effects if, just needs in fruit and vegetable surfaces moisturizing, allow the moisture vaporization of its alternative fruits and vegetables inside, it is sprayed water to fruits and vegetables by the spray equipment in vacuum chamber.Due to fruits and vegetables be generally all into case or become frame be placed in vacuum chamber, like this spray time, just can not ensure that each fruits and vegetables can both spray and obtain moisture.
Summary of the invention
The object of the invention is to the defect for prior art and deficiency, a kind of food fresh keeping vacuum precooling machine that a kind of structure is simple, reasonable in design, easy to use is provided, can uniformly for food carries out moisturizing, to supply the gasification of its moisture when vacuum pre-cooling, effectively avoid the drying loss phenomenon of food, substantially increase the freshness of food.
For achieving the above object, the technical solution used in the present invention is: it comprises vacuum chamber, delivery board, enters, gos out, vacuum pumping pump, spray system; The bottom of vacuum chamber is connected with delivery board by track, and the side of vacuum chamber is provided with enters, and its opposite side is provided with gos out, and the outside of vacuum chamber is respectively equipped with vacuum pumping pump and spray system; It also comprises support, rotating disc, connecting rod, rack, rotating shaft, motor; Delivery board is provided with several support, and support is provided with rotating disc, is connected between rotating disc by rotating shaft, and one end of rotating shaft is connected with motor by conveyer belt, motor is arranged on delivery board, and rotating disc is connected with connecting rod by connector, and the bottom of connecting rod is connected with rack.
Described rack is provided with several air-vent, and when food is laid thereon, breathing freely of instant food, is also conducive to the gasification of food water.
Described glove rack hook is located on connecting rod, carrying food for convenience detach.
Operation principle of the present invention: when food is delivered in vacuum chamber, can be sprayed water to it by spray system, open motor, driven rotary disc spins, thus drive rack to rotate, water can be sprayed on the food in rack by spray system uniformly, this makes it possible to effectively carry out moisturizing to food surface, avoids the not enough drying loss phenomenon caused of stacking moisturizing due to food.
After adopting said structure, beneficial effect of the present invention is: a kind of food fresh keeping vacuum precooling machine of the present invention, can uniformly for food carries out moisturizing, to supply the gasification of its moisture when vacuum pre-cooling, effectively avoid the drying loss phenomenon of food, substantially increase the freshness of food, and have structure simple, arrange rationally, the advantage such as cost of manufacture is low.
